Meeting at ITU headquarters in Geneva, ITU-T Study Group 11 – Protocols and test specifications – received 72 participants from 22 countries, representing a 53 per cent increase over the participation numbers recorded for its previous meeting in June 2012.

The meeting saw substantial progress made in ITU’s collaboration with the Open Geospatial Consortium (OGC) and also advanced the group’s ongoing work on software-defined networking (SDN) and conformance and interoperability (C&I) testing. Read news on the meeting's C&I achievements here

OpenGeoSMS is a standard maintained by OGC, originally developed by the Industrial Technology Research Institute (ITRI). Study Group 11 continues to collaborate with OGC with a view to formalizing OpenGeoSMS as an international standard (ITU-T Recommendation). The standard uses Short Message Service (SMS) to exchange location-based information and is considered particularly important in providing relief to individuals affected by natural disasters.

Expanding and accelerating standardization work on software-defined networking (SDN) was one of the key directives issued by ITU’s membership at last November’s World Telecommunication Standardization Assembly (WTSA-12) in Dubai.

In the interests of greater speed and flexibility in routing instructions, security and energy management of network equipment such as routers and switches, SDN proposes to decouple the control and data planes and allow for programmable interfaces to these planes; letting software do the job traditionally performed by the control plane.

ITU’s standardization work on SDN started in ITU-T Study Group 13 – Future networks including cloud computing, mobile and next-generation networks. SG 13 standardizes SDN’s functional requirements and architectures, and SG 11 thus works closely with SG 13 as it builds on this work by developing SDN’s signaling requirements and protocols.

SG 11’s recent meeting in Geneva received contributions calling for new SDN work items, including:

  • Scenarios and signaling requirements for software-defined BAN (SBAN)
  • Framework of signalling for SDN
  • Scenarios and signalling requirements of unified intelligent programmable interface for IPv6

The next meeting of SG 11 is scheduled to take place in Uganda, 6-15 November 2013, in collocation with the next meeting of SG 13 to strengthen the collaboration between these groups.

ITU-T Study Group 13 – Future Networks including Cloud Computing and NGN – has approved new standards offering a definition of the Internet of Things (IoT), characterizing the emerging IoT environment, and outlining the functional requirements of machine-oriented communication applications in an NGN context:
 
- Recommendation ITU-T Y.2060 “Overview of the Internet of Things”
- Recommendation ITU-T Y.2061 “Requirements for support of machine-oriented communication applications in the NGN environment”

ITU-T Y.2060 marks ITU members’ approval of a definition of IoT, terming it: “A global infrastructure for the Information Society, enabling advanced services by interconnecting (physical and virtual) things based on, existing and evolving, interoperable information and communication technologies.”

Recommendation ITU-T Y.2060 provides an overview of the Internet of Things (IoT), clarifying the concept and scope of IoT, identifying its fundamental characteristics and high-level requirements, and offering adetailed description of the IoT reference model. Additionally, the standardpresents an informative appendix discussing the IoT ecosystem and the business models of which it will be composed.
 
The definition is accompanied by a qualification which notes that, from a broad perspective, IoT can be perceived as a vision with technological and societal implications; which will, through the exploitation of identification, data capture, processing and communication capabilities, make full use of "Things" to offer services to all kinds of applications, whilst ensuring that security and privacy requirements are fulfilled.
 
Recommendation ITU-T Y.2061 provides an overview of machine-oriented communication (MOC) applications in next-generation network (NGN) environments; covering the NGN extensions, additions and device capabilities required to support MOC applications. Additionally, the standard’s appendices describe the actors in an MOC ecosystem and the roles they are to play, as well as a number of use cases relevant to the study of MOC applications in an NGN environment. 
 
 SG 13 has also approved Recommendation ITU-T Y.2080, Functional architecture of distributed service networking, and  has consented the approval of another fourteen new standards, the most noteworthy being Recommendations ITU-T Y.2069, Terms and definitions of the Internet of Things; Y.2705, Minimum Security Requirements for Interconnection of Emergency Telecommunications Service (ETS); Y.2027, Functional Architecture of Multi-connection; and Y.2063, Framework of Web of Things.

An international experiment deploying ITU-standardized IPTV technologies has taken place 6-8 February 2012. IPTV services were used to live-stream scenes from the Sapporo Snow Festival in Japan and to provide supporting Video-on-Demand (VoD) segments.

ITU Headquarters in Geneva received the stream from the head-end server in Japan, participating alongside organizations from Japan, Singapore and Thailand in what is the first transcontinental broadcast of a live event using IPTV technology standardized end-to-end by ITU. The connection uses native IPv6 from ITU Headquarters to Japan.

Proprietary IPTV services have hampered the growth of this exciting new market, and such experiments - together with ITU IPTV Interoperability events – are important steps towards broadening the IPTV market through globally-interoperable services. Standardized IPTV will lead to a whole new market for innovation, and ITU standards will ensure this market remains open, competitive and accessible to all.

First approved in 2009, Recommendation ITU-T H.762, a “Lightweight Interactive Multimedia Environment” (LIME) for IPTV services, is the standard with which Sapporo’s live-stream IPTV application complies. Hokkaido Television Broadcasting (HTB) developed this application, and is one of many broadcasters, manufacturers and research institutes involved in the IPTV experiments. The experiments have been organized by Japan’s National Institute of Information and Communications (NICT) and are being conducted over its IPv6 research network, Japan Gigabit Network-eXtreme (JGN-X).

Other ITU-T IPTV standards also formed part of the infrastructure: H.770 IPTV Service discovery, H.721 IPTV terminal for VoD and Linear TV, H.701 IPTV Error correction, H.750 IPTV Metadata and the Primetime Emmy Award winning H.264 Video compression codec. The experiments also used Openflow, PCE/VNTM and sa46t.

ITU-T’s Study Group 13 has consented new standards underpinning central elements of Future Networks (FNs); multiple virtual networks enabling a wide range of network services, and energy saving capabilities superior to those offered by traditional network technologies.
 
Future Networks (FNs) will provide revolutionary capabilities, facilities and services which will be difficult to support using existing network technologies. The number and range of network-based services is expected to explode in the near future, and a single network architecture will struggle to satisfy the requirements unique to each of these new services. Forming multiple physical networks will demand large outlays of capital for their installation, operation and maintenance. FNs thus need to realize diverse services through the creation of heterogenous network architectures overlaying a common physical network.

The new standards are Recommendation ITU-T Y.3011, “Framework of Network Virtualization for Future Networks”, and Recommendation ITU-T Y.3021, “Framework of Energy Saving for Future Networks.”

Recommendation Y.3011 provides a framework of network virtualization technology, a means allowing multiple virtual networks called Logically Isolated Network Partitions (LINPs) to coexist in a single physical network. Network Virtualization will create isolated, flexible networks supporting a broad range of network architectures and services. Their isolation will allow the satisfaction of services’ unique requirements, but also presents the opportunity to create experimental networks or test-beds where developers, providers and users can design and evaluate new services. The flexibility of these virtual networks is another key feature of Y.3011’s design, allowing the reconfiguration of networks to reflect the evolving characteristics of FN services and applications as they mature.

Environmental awareness is one of the fundamental objectives of FNs and energy-saving technologies form a crucial part of their development. Through their creation of network architectures for smart energy grids and ubiquitous sensor networks, FNs will do much to improve the energy efficiency of other non-ICT industry sectors. Their proliferation will however also increase the volume of energy demanded by FNs themselves. Y.3021 thus provides a framework to minimize the energy consumption of network facilities such as routers, switches and servers, as well as a method to manage the total energy consumption of FNs at all stages of their lifecycle.

ITU has given first stage approval (consent) to a new standard that enables an IPTV end user to locate and subscribe to content coming from different, independent service providers.

The standard will enable a greater deal of choice for end-users and will help service providers offer a more competitive package.

Recommendation ITU-T H.770 - Mechanisms for service discovery and selection for IPTV - describes the mechanisms for service provider discovery, service discovery and selection. Services such as linear TV and video-on-demand are addressed with metadata that describes programming and delivery protocols detailed.

ITU has given first stage approval (consent) to two new standards on fixed-mobile convergence (FMC). Operators offering FMC will be able to provide both services with a single phone, switching between networks on an ad hoc basis.

Experts say that the standards are an important step in the ongoing study and development of next generation network (NGN) mobility support and FMC service and network capabilities.

Recommendation ITU-T Y.2018 describes a mobility management and control framework and architecture for NGN. The architecture supports IP-based mobility for user devices in the NGN transport stratum. Y.2018 defines a new component called MMCF (Mobility Management and Control Functions) which includes support for handling mobile location management and handover decision and control as well as the interaction with other existing NGN functional components such as NACF (Network and Attachment Control Functions), RACF (Resource and Admission Control Functions), service control functions and transport functions.

Recommendation ITU-T Y.2808 describes principles, service and network capabilities, and architectures for IP Multimedia Subsystem (IMS) based FMC. The Recommendation describes a network architecture that uses IMS to provide the same set of services to user terminals regardless of the use of fixed or mobile access network technologies, and ensures service continuity when the point of attachment of the terminal changes between different access network technologies.

A workshop on Overlay Networking will be held on Friday, 15 May at ITU headquarters in Geneva. The event is jointly organised by ITU-T’s Future Networks and NGN Study Group (SG13) and the IEEE Next Generation Service Overlay Network (NGSON) Working Group.

Overlay networking provides the ability to customize a network via a virtual communications structure laid over the physical network. Overlay networking techniques have been proposed for various purposes, including as a way to improve Internet routing and to enhance content delivery capabilities.

The workshop will act as a way for the two groups to exchange information on their respective ongoing and planned activities in the Overlay Networking area, with a view to future collaboration.

Session topics will include: an overview of the Next Generation Service Overlay Network (NGSON) framework and status of related standards activities; the business vision behind NGSON; NGN services and capabilities and NGN architecture, and information about current and planned activities for an advanced service infrastructure from both services/capabilities and architecture perspectives.

Over 150 delegates from 25 countries met last week in Colombo, Sri Lanka to discuss standardization and regulatory issues relating to next generation networks (NGN).

The event, jointly-organised by the International Telecommunication Union (ITU) and the Commonwealth Telecommunications Organisation (CTO), and hosted by the Telecommunications Regulatory Commission (TRC) of Sri Lanka, constitutes a major step in engaging with industry stakeholders in the region and beyond on NGN standardization issues.

Participants at the event agreed to invite the ITU to establish a web-based NGN Gateway, linking NGN activities in the three ITU sectors (standardization, radiocommunication and development).

The NGN Gateway would act as an NGN information sharing point particularly aimed at developing countries and give resources such as:

  • NGN Tutorials
  • Standardization pointers
  • Governmental issue guidelines
  • Regulatory guidelines
  • Case studies on migration to NGN
  • Conformance and interoperability guidelines

NGNs are packet-based networks able to make use of multiple broadband, transport technologies, and in which service-related functions are independent from underlying transport-related technologies. Networks built on NGN technology have the potential to offer significantly lower service delivery costs, deliver a greater range of services and applications, and at the same time, support seamless and generalised mobility which will allow consistent and ubiquitous provision of services to end-users.

Various operators in the region have started the migration of their networks to NGN, however there is a pressing need to agree on a set of global standards on a range of issues, including interconnection and interoperability between networks, QoS, mobility, and IPv6.

The ITU and CTO joined forces to ensure the widest participation from Asia and beyond. Present at the event were leading operators, regulators and manufacturers including NTT, BT, Ericsson, Motorola, and ZTE.

“This is a historic event. Not only is it the first ITU-T event in Sri Lanka, it is the first joint event between ITU and CTO”, said Malcolm Johnson, Director of the Telecommunication Standardization Bureau, ITU during his welcome address.

“Sri Lanka was pleased to host this event. We are committed to such collaborative arrangements with the ITU and the CTO, as we see the ICT sector as a driving force of our economy”, Priyantha Kariyapperuma, Director-General of Sri Lanka TRC added.

ITU-T’s work on IPTV standards has progressed significantly in recent weeks with a raft of new specifications agreed.

The work has moved on from the foundation documents containing high-level architectures and frameworks to more detailed specifications. Experts say that this is an important milestone that will allow manufacturers to start implementing the specifications in their products.

A standardized IPTV environment could mean an end to walled-garden approaches where subscribers are limited to content from a particular service provider. It would for example make it easier for ex-pat subscribers to consume content from their countries of origin.

Among standards consented or approved recently include Recommendation ITU-T H.720 which gives the overview of the architecture and functional components of an IPTV terminal device and provides a high-level description of functionality necessary to support IPTV services. Also key is ITU-T H.721 which describes and specifies the functionalities of IPTV terminal devices such as set-top boxes and digital TV sets for IPTV basic services. The Recommendation also takes into consideration such conditions on content delivery as QoS.

Below is a list of recent ITU standards approved or ‘consented’ by ITU-T’s Study Group 16:


 - Rec. H.701 - Content Delivery Error Recovery for IPTV services
 - Rec. H.721 - IPTV Terminal Device: Basic Model
 - Rec. H.760 - Overview of Multimedia Application Frameworks for IPTV
 - Rec. H.761 - Nested Context Language (NCL) and Ginga-NCL for IPTV
 - Rec. H.720 - Overview of IPTV terminal devices and end systems
 - Rec. H.750 - High-level specification of metadata for IPTV services
 - Rec. H.622.1 - Architecture and functional requirements for home networks supporting IPTV services

In addition a Technical Paper has been approved that addresses the use of audio coding in services delivered over IPTV

See also New IPTV standard supports global rollout.

Membership of ITU-T gives exclusive rights to access working documents of standards under development – tomorrow’s ICTs. The vast majority of all Recommendations are available in electronic (PDF) form free of charge to all once a final editing process is complete.

ITU together with the Commonwealth Telecommunications Organisation (CTO) will hold a Forum on Next Generation Network (NGN) Standardization, in Colombo, Sri Lanka, 7 - 10 April 2009.

The event will examine the latest developments in NGNs including architecture, service requirements, network capabilities and migration. Case studies will allow attendees to learn from existing and ongoing NGN deployments from Asia-Pacific and beyond. Participants will also be kept up-to-date on recent changes to ITU-T working methods and its new mandate relating to IPv6.

Sessions will additionally focus on cybersecurity, ICTs and climate change, traffic accounting principles and QoS. There will be discussion of policy, regulatory and developmental issues related to NGNs and a report on the main results of the World Telecommunication Standardization Assembly (WTSA-08).

NGN growth in Asia-Pacific is in different stages of development. In a climate of many complex economic, technological, strategic and operational considerations, including the cost of implementation, changing marketplaces, complex migration scenarios and regulatory uncertainties, the role and importance of standardization is highlighted more than ever before.

By leveraging on the experiences of renowned experts in the ICT field, the conference aims to allow participants to explore a wide spectrum of NGN standardization and related topics, with a special focus on the Asia-Pacific region.

A new ITU group has been set up to collect and identify visions of future networks, based on new technologies.

The move to set up the Focus Group on Future Networks (FG-FN) follows a request from members to push forward study in this area and strong interest expressed by the academic community during the ITU-T Kaleidoscope event in May 2008.

The term Future Networks has come to encompass such projects as IRTF (International), GENI/FIND (US), FP7/FIRE (EU), CNGI (China), AKARI/NwGN (Japan), FIF (Korea) as well as standardization works in ISO/IEC JTC1/SC6.

Experts say that taking into consideration the importance of global connectivity and interoperability between devices, networks, services and applications, global harmonization between these different activities is extremely important and necessary to build up globally interoperable future ICT infrastructures.

Given ITU-T’s role as a global ICT standards organization, it is in the best position to support the development of global and harmonized frameworks (e.g. requirements, functional architectures and protocols) collaborating with all relevant entities and activities.

The provisional dates and venue for the first meeting of the group are 6-10 July, Geneva.

A major milestone for providing global IPTV has been reached with the approval of a new ITU standard, giving requirements for the support of IPTV services.

Experts say that standards are essential for the rollout of global IPTV services. While we have already seen a first generation of IPTV services, a second generation may see a change in regulation or market demand that will require interoperation between service and/or network providers. A potential outcome of this will be that a customer can go into a shop, buy an IPTV box, call their network operator and sign-up, and then access services from a range of third party service providers. It is to meet needs such as this the value of ITU’s work on standardization will be realised.

IPTV, defined by ITU-T as “multimedia services such as television/video/ audio/text/graphics/data delivered over IP-based networks managed to support the required level of quality of service (QoS)/quality of experience (QoE), security, interactivity and reliability”, is one of the most significant business cases and drivers for the deployment of next generation networks (NGN).

The standard, Recommendation ITU-T Y.1901, specifies high level requirements for the support of IPTV services, including requirements concerning service offering, QoS/QoE, service and content protection, middleware, content, network and end system aspects. Y.1901 and previously approved Recommendation ITU-T Y.1910, “IPTV functional architecture”, plus various other IPTV related ITU-T Recommendations, constitute an initial set of IPTV standards enabling equipment vendors, including consumer electronics suppliers, to roll-out standardized IPTV products. Deployment of ITU-T compliant products will enable service providers to offer value added services like traditional (linear) TV, video on demand (VoD) and interactive TV over IP-based managed networks such as NGN.

Y.1901 has been developed with a truly international effort at ITU-T IPTV-GSI (IPTV Global Standards Initiative) events, with the active participation of administrations, service providers and equipment vendors from a large number of countries, including, but not limited to Canada, China, France, Japan, Korea, United Kingdom and United States.

ITU-T standardization activities related to IPTV continue in various ITU-T Study Groups, in cooperation with relevant standard developing organizations, forums and consortia, including ATIS IPTV Interoperability Forum, ETSI TISPAN, Broadband Forum, Digital Video Broadcasting project and Home Gateway Initiative.

A key standard – ITU-T Recommendation – on identity management (IdM) has been approved by the ITU-T.

Entitled “NGN Identity Management Framework,” the Recommendation (Y.2720) specifies a structured approach for designing, defining, and implementing interoperable identity management (IdM) solutions for next generation networks (NGN).

The term IdM is understood as "management by providers of trusted attributes of an entity such as a subscriber, a device, or a provider." IdM promises to reduce the need for multiple user names and passwords for each online service used, while maintaining privacy of personal information. Global IdM solutions will help diminish identity theft and fraud. Further, IdM is one of the key enablers for a simplified and secure interaction between customers and services such as e-commerce.

ITU-T Y.2720 results from a truly international effort involving governments, operators and equipment vendors from various countries, including China, Japan, Korea, the United States, and United Kingdom.

In a heterogeneous, converged environment such as NGN, the assurance, security and management of identity information faces unique challenges, including:

  • End users are increasingly using multiple identities
  • These identities may be associated with differing contexts and service privileges
  • The identities may only partially identify the end user
  • The identities may be used anywhere, anytime
  • The identities may not be interoperable between providers

Y.2720 addresses these challenges and identifies a set of functions and capabilities (e.g., administration, discovery, communication exchanges, correlation and binding, policy enforcement, authentication and authorization) to allow:

  • Assurance of identity information (e.g., identifiers, credentials, and attributes)
  • Assurance of the identity of an entity (e.g., users/subscribers, user devices, service providers, and network elements)
  • Enablement of business and security applications.

The framework defined in Y.2720 provides a holistic view of IdM in NGN. It lays the foundation for developing specific aspects of IdM, including detailed requirements, mechanisms and procedures which will form the next stage of work for ITU-T experts.

The first global standard offering an in-home, high-speed network capable of delivering room-to-room HDTV has been agreed by ITU. The standard, published under the G.hn banner, promises high quality multimedia over power, coaxial, phone and other home wiring. It will give up to 20 times the throughput of existing wireless technologies and three times that of existing wired technologies.

The specifications will be used by chip manufacturers to build transceivers that can be incorporated into set-top boxes, residential gateways, home computers, home audio systems, DVD players, TVs or any other device that might be connected to a network now or in the future. Experts say that silicon companies will immediately start incorporating the specifications into transceivers, implying that G.hn-compliant products could be on the market as early as 2010.

Joyce Putscher, Principal Analyst at market research firm In-Stat, said, “Service operators have been looking for an international standard that encompasses multiple existing-wire mediums for video distribution. G.hn meets that requirement and it seems clear that with significant industry backing from service providers, semiconductor and equipment vendors, and the fast rate at which the process is moving to achieve a standard, we will see first equipment by 2010.”

“There’s a clear market need for a unified networking approach,” said Malcolm Johnson, Director of ITU’s Telecommunication Standardization Bureau. “With G.hn, every wire in every home around the world can become part of a home entertainment network. This will enable seamless communication between computers, HDTVs and telephones over existing wires. I expect that this exciting new technology will also foster innovations such as energy efficient smart appliances, home automation and telemedicine devices.”

Work on G.hn was started at the instigation of service providers looking to extend broadband and video services in the home. As well as its offer of greater speed, it may be bundled as complementary to Wi-Fi where G.hn offers greater coverage, extending, for example, to areas of a house where Wi-Fi does not reach.

The standard has achieved remarkable industry backing even before its publication. An industry group — the HomeGrid Forum — has been formed specifically to back G.hn. The goal of HomeGrid Forum is to market G.hn worldwide and to create a compliance and interoperability programme to ensure that products based on the standard will operate in any home around the world.

Other industry analysts backing the standard include Michael Wolf, Research Director at ABI Research. “If G.hn sees integration into carrier devices by 2010, we expect that some 42 million G.hn-compliant nodes will ship in 2013 in devices such as set-top boxes, residential gateways and other service provider CPE hardware,” Wolf said.

“A single, unified technology for multimedia networks over power lines, coaxial cable, and phone lines has the potential to enable a simple, easy-to-use means of networking devices in the home,” said Kurt Scherf, analyst with market analyst firm Parks Associates. “We believe ITU’s work is an important step towards eliminating fragmentation in the industry and in achieving the vision of a networked home.”

Recommendation ITU-T G.9960 focuses on the physical or PHY layer, giving the data bit rate and quality of service necessary for triple-play residential services as well as business-type services delivered over xDSL, PON, or other access technology. In step with ITU guidelines on new standards development, several power saving modes have been incorporated. Ongoing work is focused on the media access control (MAC) layer.

The seventh in a series of ITU-T Technology Watch Briefing Reports covers next generation networks (NGN) and energy efficiency.

The report examines the relationship between climate change and NGN by analyzing energy efficiency and applications.

NGNs are seen by many as the new network architecture that will unify today’s fixed, mobile and broadcast networks. This innovative technology is expected to bring about greater energy efficiency than legacy networks by, for example, reducing the number of switching centres and increased temperature tolerance within those centres. NGNs are expected by some commentators to reduce energy consumption by 40 per cent compared to today’s public switched telephone network (PSTN).

This report presents an overview of the main characteristics of NGN and looks at how NGN can minimize the power consumption of the network, transmission and end-user equipment and in data centres. It examines the energy savings that can be indirectly obtained from greater NGN usage, such as remote collaboration and ITU-T standardization work on NGN and climate change.

ITU-T has issued a call for papers for its Kaleidoscope 2009 event - Innovations for Digital Inclusion - to be held in Mar del Plata, Argentina, 31 August – 1 September 2009. The event is the second in a series of peer-reviewed academic conferences that aims at increasing the dialogue between experts working on the standardization of information and communications technologies (ICT) and academia.

The first Kaleidoscope event – Innovations in NGN - was held in Geneva, 12-13 May 2008.

Kaleidoscope 2009 is calling for original academic papers offering innovative approaches to digital inclusion. Prizes totalling USD 10k will be granted to the best papers, as judged by the organizing and programme committees. In addition a young author recognition certificate will be granted to authors presenting papers who are pursuing their studies and do not – at the time of the event - have a PhD. Accepted papers will be presented during the event, published in the proceedings and made available through IEEE Xplore. The best papers will be evaluated for potential publication in IEEE Communications Magazine.

Kaleidoscope-2009 will analyze technologies, services and applications five years and beyond that will capitalize on NGN infrastructure and promote digital inclusion. The event will cover multidisciplinary aspects, including regulatory and societal challenges as well as analysis of standardization needed.

Innovative technologies will help bring the benefits of ICTs to all segments of the population, in particular those in underserved communities and developing countries.

ITU-T NGN expert, Seungyun Lee, from the Korean Electronics and Telecommunications Research Institute (Korea) will make a presentation at the upcoming Telemanagement Forum’s (TMF), Service Delivery Summit. Lee’s presentation is entitled Towards a SOA/WS enabled NGN Open Service Environment - ongoing developments in ITU-T SG13.

His abstract:

“Across the telecom industry, much work is underway to separate the communications capabilities in today’s networks from the networks themselves and to make those capabilities available for integration into the applications in the IT industry. This effort is making possible a rich menu of modular building blocks that can be easily mixed and matched with building blocks from the IT industry to form wholly new kinds of multimedia services and automated business processes that marry the rich content, data applications, and business processes of the IT world with the intelligent, real-time, in-the-network functions of the telecom domain.

Key to this effort at the core of future multimedia service architectures are the SOA (Service Oriented Architecture) and the WS (Web Services) frameworks. ITU-T SG13 has started the development of specifications towards the integration of SOA and WS technical approaches in the NGN context. In line with approved and ongoing ITU-T recommendations, this presentation, building over the basic concept of NGN capabilities, will introduce some key requirements and capabilities for the support of an advanced open service environment in NGN. The integration of SOA and WS in NGN will be then examined, including some achievements and current challenges for the standards community.”

The event focuses on the drive to create an open, industry owned blueprint of how new and exciting services can be created and delivered across complex value chains. It examines standardization of key elements of service delivery platforms (SDPs), which will open up the ability of partners to add end-user value by working seamlessly together to deliver novel services, created and delivered in a fraction of the time and cost it takes today, while dramatically cutting integration costs and avoiding vendor lock-in.

A recent meeting of ITU-T’s Study Group 12 saw consent – first stage of the approval process - on two key new standards for IPTV.

The first ITU-T Recommendation defines user requirements for Quality of Experience (QoE) for IPTV services.

Quality of Experience (QoE) is defined thus: The overall acceptability of an application or service, as perceived subjectively by the end-user.

The new Recommendation (ITU-T Rec. G.1080) defines QoE requirements from an end user perspective, agnostic to network deployment architectures and transport protocols. They are specified as end-to-end and information is provided on how they influence network transport and application layer behaviour. QoE requirements for video, audio, text, graphics, control functions and meta-data are provided.

The second ITU-T Rec. (ITU-T Rec. G.1081) consented defines performance monitoring for IPTV. The goal of this is to provide higher QoS/QoE to customers by identifying, localizing and quantifying service and network issues. IPTV performance monitoring can be software based, hardware based, or a hybrid.

Monitoring parameters, monitoring points and monitoring methods are defined that allow the service provider/network operator to monitor the performance of the service delivery to the end user.

Successful deployment of IPTV services requires performance to be monitored at the customer premise (e.g. set-top-box), key aggregation points such as DSL Access Multiplexer (DSLAM) or cable modem termination system (CMTS) and at interconnect points between disparate network domains. Performance monitoring can help:

  • Find errors in an end-to-end system (system debugging)
  • Check the resource utilization and the work load of system components
  • Compare values (metrics) regarding performance of different system deployments
  • Provide a base for modelling the system
  • Find system bottlenecks
  • Optimize IPTV network deployment
  • Ensure that system performance does not degrade with time.

IPTV standards are progressing rapidly through ITU-T's IPTV Global Standards Initiative (GSI). With successful first generation IPTV services offered by many service providers worldwide standards are seen as vital to boost next generation services where a customer may go into shop, buy an IPTV box, call their network operator and sign-up and then access services from a range of third party service providers. More Recommmendations are expected to be consented at the upcoming IPTV-GSI meeting 23-27 June in Geneva.

ITU-T and IEEE Communications Society (Comsoc) have signed a memorandum of understanding (MoU) aiming to better collaboration between academia and the standards world.

The document was signed during the first ITU-T Kaleidoscope conference, Innovations in NGN - Future Network and Services by Malcolm Johnson, Director of the ITU Telecommunication Standardization Bureau, and Alexander D. Gelman, Director of Standards, IEEE ComSoc.

The objective of the MoU is to increase cooperation particularly in the area of events (e.g. workshops, seminars, symposia, forums and academic conferences) and publications.

The conference was the first in a series that aims at increasing the dialogue between academia, research institutes and ITU experts working on the standardization of ICTs. Held in Geneva, 12-13 May, it was attended by more than 220 participants.

Organized by ITU-T with IEEE ComSoc as Technical Co-Sponsor and supported by Cisco, Intel, the International Communications Foundation of Japan) and Sun Microsystems, the conference brought together the best academic minds from around the world to present their future visions for Next-Generation Networks (NGN).

Among over 140 papers submitted. 53 papers were presented and the best three were awarded prizes totaling $10,000 kindly donated by Cisco. These papers will be included in a future special edition of the IEEE Communications Magazine.

The winning papers were:

  • Architecture and business model of open heterogeneous mobile network, Yoshitoshi Murata; Mikio Hasegawa; Homare Murakami; Hiroshi Harada; Shuzo Kato.
  • Differential phase shift quantum key distribution, Hiroki Takesue; Toshimori Honjo; Kiyoshi Tamaki; Yasuhiro Tokura.
  • Open API standardisation for the NGN platform, Catherine Mulligan.

In addition to the prize pool 16 entrants received a Young Author Recognition Certificate, a recognition ITU will continue to give in future.

The conference highlighted technologies, services and applications that will capitalize on the NGN infrastructure as well as looking beyond NGN. It covered multidisciplinary aspects related to the deployment of NGN, including analysis of regulatory and societal challenges.

Attendees agreed on the the importance of strong collaboration between ITU-T, academia, and research institutes, which would be to the benefit all. The many academics in attendance expressed the importance of the role of universities in the standardization process. One issue discussed was the lowering of the ITU membership fee for such organizations, a topic that will likely be discussed at the coming WTSA-08 .

Building on the success of the first Kaleidoscope event, a second conference is planned for 2009.

ITU-T IPTV experts Ghassem Koleyni and Simon Jones will lead a live web seminar (webinar) on IPTV standardization, May 7 at 1600 CET.

Click here to register, for the webinar hosted by industry analyst Heavy Reading. By registering you will be able to listen to and take part in discussion as well as view presentation slides.

Koleyni and Jones will present standardization from an ITU perspective with experts from other standards bodies, including the DSL Forum and ATIS, explaining how they have worked with ITU to produce the first set of global IPTV specifications, available here. Malcolm Johnson, Director ITU Telecommunication Standardization Bureau said: “I encourage anyone involved in the deployment of IPTV services at any level to take this opportunity to learn about this important set of standards as well as quiz our experts on the topic.

We have already seen first generation IPTV services and as these mature we may see a change in regulation or market demand that will require interoperation between service and/or network providers. A potential outcome of this will be that a customer can go into shop, buy an IPTV box, call their network operator and sign-up and then access services from a range of third party service providers. It is to meet that need that the value of ITU’s work on standardisation will be realised. ”

An ITU event will bring together the best academic minds from around the world to present their future visions for next generation networks (NGN). The three best papers will be awarded from a prize fund donated by Cisco totaling $10,000.

Innovations in NGN, 12-13 May, Geneva is the first in a series of conferences under the banner ‘Kaleidoscope’ that will bring closer ties between ITU, academia and research organizations. The event, technically co-sponsored by the IEEE Communications Society attracted around 140 contributions with its initial call for papers. From this, 54 of the most visionary papers have been selected by a review panel of 140 experts from around the world for presentation at the conference. The event will also host the signing of a memorandum of understanding (MoU) between ITU and IEEE Communications Society.

Innovations in NGN will highlight technologies, services and applications five years and beyond that will capitalize on the NGN infrastructure and lead to the ubiquitous network society in which information can be accessed anywhere and anytime by anyone and anything. It will also cover multidisciplinary aspects related to the deployment of NGN, including analysis of regulatory and societal challenges.

Malcolm Johnson, Director of the Telecommunication Standardization Bureau: “Technology is a critical determinant of sustainable growth and poverty reduction. And, education is key to the accelerated development of information and communications technologies (ICT) and contributes to the increased use of these technologies all over the world. Without the involvement of the world’s universities and other academic and research institutions we would not have reached the level of innovation that we see today. The Kaleidoscope series is an excellent innitiative to capitalize on the fruitful relationship that we already have with academia and take it to another level.”

ITU has a long history of collaboration with academia and many standards (ITU-T Recommendations) have been developed with academic input. Some leading Study Group positions are held by university professors. The Kaleidoscope initiative will encourage a new type of engagement along the lines of an academic conference. Authors whose works are selected for the event’s proceedings will gain extra academic recognition by being published online by IEEE. The standards world will profit from new ideas for possible future development.

Innovations in NGN is to inspire contributions towards a kaleidoscopic view of communication habits for the future. We know what NGN is in terms of the underlying technology, but we don’t know what services will emerge, how NGN will affect the marketplace for ICT, and how society will be affected. This, first in the series of Kaleidoscope conferences is free for anyone to attend and will shed light on some of these questions as well as inspire debate and future work on the future of ICT and ICT standardization. Please register at www.itu.int/ITU-T/uni/kaleidoscope/.

ITU-T is seeking sponsors to join Cisco, ICF and Sun Microsystems and help fund the various activities connected to the event including publication of proceedings, coffee-breaks and reception. For more details contact kaleidoscope@itu.int.

When you enter a modern office building, such as ITU-T’s office in Geneva, it is quite common for the glass doors to open automatically and for lights to come on as you enter a darkened room. This “magic” is achieved by motion sensors. But entering a building in the future, you might be welcomed by name with a personal greeting and given security access suitable to your status (e.g., employee, delegate, newcomer). To do this without human intervention would require not only intelligent sensors but also perhaps ID tags and readers and interaction with a database.

In a new Technology Watch briefing report from ITU-T, the term “Ubiquitous Sensor Networks” (USN) is used to describe networks of intelligent sensor nodes that could be deployed “anywhere, anytime, by anyone and anything”. The technology has huge potential as it could generate applications in a wide range of civilian and military fields, including ensuring safety and security, environment and habitat monitoring, real-time healthcare, landmine detection and intelligent transport systems (ITS).

Sensor nodes may vary enormously in size, cost and complexity. Their characteristics are highly application-specific. Depending on the sensor type, the links between sensors may be provided by either wired or wireless communication. Energy-efficient operation is an important requirement for scenarios where sensor nodes are deployed in hazardous or inaccessible environments.

The variability of USN poses a challenge to researchers and a number of different standards development organizations (SDOs) are already engaged int this field. Within ITU-T, USN standardization is being carried out under the auspices of the Next-Generation Network Global Standards Initiative (NGN-GSI). The new report, the fourth in a series of ITU-T Technology Watch Briefing Reports, describes the different components of USN, notes the standardization work currently going on in ITU-T, and gives an overview of the different fields of applications of USN in both, developed and developing countries.

A new report from ITU-T shows how Information and communications technologies (ICTs) contribute to global warming, but also how they can be used to monitor climate change, to mitigate its effects, to improve energy efficiency and to reduce carbon emissions in other sectors of the economy. The report -- ICTs and Climate Change -- is the third in the new series of Technology Watch Briefing Reports, launched by ITU-T in October 2007. It has been submitted to TSAG for further discussion at its upcoming meeting, 3-7 December. It is planned that an ITU symposium on this topic will be held in 2008.

Since 1970, the production of greenhouse gases has risen by more than 70 per cent, and this is having a global effect in warming the planet, causing changing weather patterns, rising sea-levels, desertification, shrinking ice cover and other worrying long-term effects. The UN Intergovernmental Panel on Climate Change (IPCC) foresees a further rise in average global temperatures of between 1.4 and 5.8 degrees centigrade by 2030. Climate change is a concern for all of humanity and requires efforts on the part of all sectors of society, including the ICT sector. Although ICTs contribute only an estimated 2.5 per cent of total greenhouse gases, this share is set to grow as usage of ICTs expands globally, growing at a faster rate than the general economy.

ICTs are thus part of the cause of global warming, but they can also be part of the solution, for instance through the promotion of carbon displacement technologies. ICTs are also vital in monitoring the spread of global warming. One specific contribution ICTs can make is through the substitution of travel by electronic forms of communication, such as telephone calls, email or video-conferencing, all of which benefit from ITU-T¡¯s standardization work. In particular, high-performance video-conferencing, or telepresence (the topic of the second Technology Watch Briefing Report), can give the impression of 'being there, without going there'. Furthermore, ITU-T itself is also contributing to a greener future through its decision to make ITU-T Recommendations freely available online. In the mid 1990s, more than one million publications were printed by ITU but, with free Recommendations now available in electronic form, this has been cut to just a few thousand that are still printed, and carbon emissions from transport of printed copies and CD-ROMs has been greatly reduced.

Do you remember your last video conference? Blurry faces on tiny screens, with sound that doesn’t quite synchronize with the stilted movement of the lips. After the laborious setup of cameras and microphones, you seem to spend more time worrying about technical problems than talking about the topic at hand, with repeated loss of connection. As frustration grows, and attention wanders, it is difficult to avoid the feeling that you should have arranged a face-to-face meeting instead.

 

A new set of technologies – referred to as Telepresence – will give users the illusion of sitting on the opposite side of the remote party’s conference table. High-definition (HD) video images and audio are transmitted via packed-based Next-Generation Networks (NGN), connecting conference rooms around the world, and covering distances of thousands of miles with zero latency. While the network infrastructure remains transparent to the user, vendors equip conference rooms with high-end displays, cameras, loudspeakers and furniture to enhance the conferencing experience. Telepresence-systems are already available on the market, and involved companies go as far as identifying the technology as a potential billion dollar market, for solution vendors as well as for network service providers (NSP).

 

A new ITU-T Briefing Report on Telepresence has been released as part of the Technology Watch function, which evaluates the market potential and different fields of application of Telepresence solutions in both, developed and developing countries. The report notes the standardization work currently going on in ITU, including the consideration of migrating currently used multimedia protocols, such as H.323 and SIP into a new generation of multimedia protocols, called H.325 or Advanced Multimedia Systems (AMS), that takes into consideration special aspects of security, flexibility, QoS, and support for mobile devices. This report is the second of a new series of Technology Watch Briefing Reports looking at emerging new technologies.

Study Group 9 consented Recommendations on IPTV and advanced HDTV proposals during meetings held Oct. 29 - Nov. 2, Louisville, Colorado.

The meeting saw participation from all around the world with several delegates from developing countries including Kenya, India and Trinidad and Tobago.

Recommendation J.700 - IPTV Service Requirements and Framework for Secondary Distribution - defines service level requirements and an architectural framework for telecommunication networks to provide new services based on IPTV. It refers to "secondary distribution" which means use of a transmission channel for distribution of video/audio programs to users at large, for example by an over-the-air broadcast channel or by means of a fiber or cable network.

The Recommendation is extensive and includes requirements for network elements as well as customer premises equipment (CPE), including middleware application interfaces which consist of software libraries that provide uniform access to system services. It leverages existing deployed technologies, such as MPEG, DOCSIS, GEM (Globally Executable MHP), and IPCablecom to provide a smooth path for operators to integrate IPTV technology into their networks. While in the process of developing this Recommendation considerable liaison with other Study Groups and the IPTV Focus Group was carried out.

In addition to the IPTV work, Recommendations relating to second - and third - generation IPCablecom were consented. Equipment based on IPCablecom Recommendations, such as modems, set-top boxes, signalling equipment, interactive television application platform interfaces, digital program insertion, and others have had widespread implementation in networks in Asia, Europe, and North America.

The new Recommendations add to a suite of more than 25 which have been developed for cable and hybrid networks primarily designed for television and sound program delivery to the home.

Large screen digital imagery (LSDI) is a family of digital imagery systems that includes very large screen presentation of programmes similar to the non-digital IMAX and OMNIMAX systems. LSDI is described as an optimal approach to the presentation of high-definition television (HDTV) programmes, to a collective audience on cinema-like screens in a cinema-like environment. An earlier approved Recommendation J.600 addresses use of a broadband service or channel for transferring audio or video information to a production center where post-production processing may take place before subsequent distribution. At this meeting work towards a new Recommendation - Network Service Operator's Requirements for Real-time Transmission of exLSDI Signals under Parallel Processing Functionality - was significantly progressed. This Recommendation is related to the transport of program signals conforming to the higher levels of the LSDI expanded hierarchy as used for contribution and primary distribution. The term contribution means use of a broadband service or channel for transferring audio or video information to a production center where post-production processing may take place before subsequent distribution. Primary distribution is the use of a transmission channel for transferring audio and/or video information from a production center to one or several destination points; for example, to a broadcast transmitting center or the headend of a cable distribution network. Work on LSDI takes place with interactions between ITU-T Study Group 9, ITU-R Study Group 6, and other bodies external to the ITU.

Imagine a future in which cars will be able to foresee and avoid collisions, navigate the quickest route to their destination, making use of up-to-the-minute traffic reports, identify the nearest available parking slot and minimize their carbon emissions. Indeed, imagine a future where cars can largely drive themselves, leaving their passengers to use the free time to watch the sports game on live TV.

All of these possibilities already exist within the laboratories of car manufacturers and some are already available commercially. But they rely on communications links that must be increasingly high-capacity and long range to deal with the full range of requirements of future transport users. The generic technology they use is called Intelligent Transport Systems (ITS). The requirement for future standards in the ITS field is to be able to provide multiple services, over multiple different platforms, that will work in different countries (as vehicles can easily cross borders), while maintaining a simple-to-use interface that requires minimum intervention from the driver.

This, then, is the rationale behind an ongoing effort, launched by the International Organisation for Standardization (ISO) in 2003, under the auspices of Working Group 16 of ISO Technical Committee 204, and promoted by the more recently created industry association - The CALM Forum - to develop a new family of ITS standards with the overall branding of Continuous Air-interface, Long and Medium range (CALM).

A new ITU-T Briefing Report on CALM has been released as part of the Technology Watch function, which evaluates its potential as a new area for ITU standardization work (for instance, integrated with Next-Generation Networks) and its likely implications for developing countries. The report notes the work currently going on in ITU on ITS, including the forthcoming Fully Networked Car III workshop, to be held on 3-5 March 2008 in Geneva. It is planned that this will be the first of a series of new Briefing Reports looking at emerging new technologies.

The government of Rwanda generously hosted ITU’s first ever global Forum on Bridging the ICT standardization and development gap between developed and developing countries, in Kigali, Rwanda, 2-4 October. Participants welcomed the recent establishment of a special fund for voluntary contributions from world governments and industry to address the issue.

The ICT standardization gap refers to the shortage of human resources in developing countries, relative to developed ones, in terms of being able to participate effectively in the standards-making and implementation process. Standards are an essential tool in bridging the digital divide, in reducing costs, and bringing vital aid to developing countries in building their infrastructure and encouraging economic development.

Over 160 participants from 38 countries took part in the meeting, with several countries being represented at government Minister or company CEO level. The conclusions of the Forum, outlining the importance of addressing the standardization gap, will be provided as input to the upcoming Connect Africa summit to be held in Kigali, 29-30 October.

The Forum was formally opened by H.E. Albert Butare, Minister of State in charge of Energy and Communications. He drew attention to the country’s National Information and Communications Infrastructure (NICI) Plan where the aim is to focus on the benefits of ICTs for national development and prosperity so that by 2020 Rwanda will have achieved middle-income status as a knowledge-based economy. The Minister welcomed the support being given by ITU and the international community in helping Rwanda to achieve its goals.

Mr. Malcolm Johnson, Director of the ITU Telecommunication Standardization Bureau, speaking in Kigali at the opening of the Forum, said: “The significance of the standardization gap is that it contributes to the persistence of the wider digital divide in ICTs. That is because one of the underlying causes of the digital divide is unequal access to technology and the ability to implement and use that technology. The process of technology transfer and implementation will happen much faster when African engineers can participate in standards development, particularly at the requirements-gathering stage, and are familiar with the relevant standards.”

Meeting participants agreed that a sustained commitment to raising standards awareness and to capacity-building is of particular importance and the meeting called on the ITU to step up its efforts, welcoming ITU’s organisation of a Global Standardization Symposium to address the issue. This will be held on 20 October 2008 just ahead of the next World Telecommunication Standardization Assembly (WTSA-08), planned for South Africa.

A chairman’s report from the Forum is available online as well as a full set of presentations: here.

ITU is holding a workshop - Making accessibility a reality in emerging technologies - at the second meeting of the Internet Governance Forum (IGF) in Rio de Janeiro, 13 November, 1430-1600.

ITU’s standardization arm - ITU-T - has a long history of providing standards in the field of accessibility. It started in the early 90's with the international text telephone standard, ITU-T Recommendation V.18, which ties together text telephone protocols allowing different textphone types to communicate.

ITU-T’s accessibility experts have helped to incorporate accessibility needs into standards for multimedia, network interoperability, multimedia service descriptions and multimedia conferencing.

The latest work has focused on taking accessibility needs into account in the development of all standards. For this reason an ‘Accessibility Checklist’ has been created for the makers of standards to ensure that they are taking into account the needs of those to whom accessibility to ICTs are restricted, the deaf or hard-of-hearing for example. Experts say that such a list will help to ensure that accessibility needs are taken into account at an early stage, rather than ‘retrofitted’.

An area of current intensive standardization activity is that on the next generation network (NGN). Accessibility features have been included at the first stage of standards work where requirements are defined. However it is important that these needs are taken into account as work progresses.

This workshop, organized by ITU, as part of the Internet Governance Forum brings together experts from around the world to examine how best to take into account accessibility needs in emerging technologies.

Standards produced by ITU — ITU-T Recommendations — are now available without charge. The announcement follows a highly successful trial conducted from January−October 2007, during which some two million ITU-T Recommendations were downloaded throughout the world.

The experiment’s aim was to “increase the visibility and easy availability of the output of ITU-T”. Offering standards for free is a significant step for the standards community as well as the wider information and communication technologies (ICT) industry. Now, anyone with Internet access will be able to download one of over 3000 ITU-T Recommendations that underpin most of the world’s ICT. The move further demonstrates ITU’s commitment to bridging the digital divide by extending the results of its work to the global community.

Director of ITU’s Telecommunication Standardization Bureau (TSB) Malcolm Johnson, presenting the results of the trial to the 2007 meeting of ITU’s Council, said that not only had the experiment been a success in raising awareness of ITU-T, it would also attract new members. Most importantly, he noted, it had helped efforts to bridge the “standardization gap” between countries with resources to pursue standardization issues and those without. “There has been very positive feedback from developing countries,” said Johnson. “Last year exactly 500 ITU-T Recommendations had been sold to developing countries; this year, after allowing free access, they have downloaded some 300 000.”

ITU-T Recommendations are developed in a unique contribution-driven and consensus-based environment by industry and government members, with industry providing the most significant input. A strong focus of current standards work is providing the foundations for the so-called next-generation network (NGN). Other key areas include IPTV, ICT in vehicles, cybersecurity, quality of service, multimedia, emergency communications and standards for access, such as VDSL 2 — very high speed digital subscriber line 2, the newest and most advanced standard of DSL broadband wireline communications.

IEEE Communications Society has been announced as Technical Co-Sponsor of the International Telecommunication Union’s upcoming Innovations in Next Generation Networks event to be held in Geneva, Switzerland May 2008. The partnership means that IEEE Communications Society will encourage members to respond to a call for papers issued by ITU.

The call for papers is to inspire contributions towards a kaleidoscopic view of communication habits for the future. We know what NGN is in terms of the underlying technology, but we don’t know what services will emerge, how NGN will affect the marketplace for ICT, and how society will be affected. Innovations in NGN is the first in a series of events, under the banner “Kaleidoscope Conferences”, that aims at increasing the dialogue between academia and experts working on the standardization of information and communications technologies (ICT).

By viewing technologies through a kaleidoscope, these forward looking conferences will also seek to identify new topics for standardization. Innovations in NGN will bring together visionary ideas on the future of NGN. It will highlight technologies, services and applications five years and beyond that will capitalize on the NGN infrastructure and lead to the ubiquitous network society in which information can be accessed anywhere and anytime by anyone and anything. The event will also cover multidisciplinary aspects related to the deployment of NGN, including analysis of regulatory and societal challenges.

ITU-T’s multimedia Study Group 16 met in Geneva, July, with over twenty standards entering the final stage of ITU-T’s approval process. The ITU secretariat says that the meeting saw record numbers of participants and contributions. Work on the use of tag-based identification (including RFID) for multimedia in particular saw great interest and progress.


Key achievements of the meeting include the setting up of new Questions – ITU-T’s term for work area - to advance work on the third generation multimedia system that will replace the currently used H.323 and SIP multimedia protocols and a second Question on multimedia application platforms and end systems for IPTV. See separate stories – Third gen multimedia system work accelerates and Question on multimedia application platforms and end systems for IPTV.

A new Question – ITU-T’s term for work area - to advance work on the third generation multimedia system that will eventually replace the currently used H.323 will start work pending formal approval at the next meeting of Study Group 16.

H.323 is the ITU standard for interoperability in audio, video and data transmissions over IP. It is the most widely used voice over IP (VoIP) communication protocol worldwide. It is estimated that systems using H.323 carry billions of voice minutes each month. The rollout of the next generation network (NGN) will bring with it in a new era of multimedia communications and with it the need for a new protocol.

In the mid-1990s, the ITU began work on H.323, which quickly became the dominant protocol for LAN-based videoconferencing, as well as a protocol used for transporting voice calls around the world. H.323 was developed in parallel with the Internet Engineering Task Force’s (IETF) Session Initiation Protocol (SIP), and was effective in facilitating a migration from circuit-switched networks to packet-switched networks. Sharing similar capabilities and similar design philosophies and being produced in the same time period, H.323 and SIP are classified as second generation systems.

Now, more than 11 years since the introduction of second generation systems, ITU-T SG 16 is again looking toward the future of multimedia systems as the ITU-T also undertakes a study to introduce the next generation network (NGN). The NGN holds the promise of revolutionizing communication as we know it and multimedia will be an important part of any new network technology.

Work on the third generation multimedia system will entail the creation of multiple new ITU-T Recommendations that will specify system architecture, system components, and one or more protocols at the service and application layer. The primary objective is to deliver a new advanced multimedia system that operates on NGN, taking advantage of its features, and will also operate on non-NGN packet-switched networks.

This Question will examine technologies such as various IP technologies, wireless technologies, and distributed computing capabilities in order to realize a system that will enable users to communicate using, as examples, voice and audio, video, electronic whiteboard, application sharing, real-time text, and file transfer across one or more communicating devices (e.g. smart phones, TV set-top boxes, game consoles, handheld game/entertainment machines, digital cameras and Internet “appliances”).

Unlike previous generation systems, this new system will enable independent application developers to create system components that are able to seamlessly interface with the system in order to deliver any one or more of the aforementioned modes of communication. There is a strong desire to move away from the “monolithic applications” that were distinctive of second generation systems, to a system that enables components to “plug in” to the system, either locally or remotely using various wired or wireless technologies, to deliver an enhanced user experience. To meet that objective, this Question will study the various interfaces between these components and the technologies that might be used to tie them together.

The study includes among other subjects:

• Downloadable codecs

• System decomposition

• Discovery of services

• Support for transcoding functionality (e.g. text to speech)

• Dynamic device discovery

• Application plug in

• Consideration of various business models

• Integrated QoS, security and mobility functionality

Experts have set deadlines for the Identification of Requirements - Q1/2008, and basic architecture - Q1/2009.

A new Question – ITU-T’s term for work area – on multimedia application platforms and end systems for IPTV will start work pending formal approval at the next meeting of Study Group 16.

Experts say that with the surge of multimedia services such as video streaming and the desire to offer IPTV services, the market is in serious need of standardized interoperable solutions, especially at the multimedia applications layer. Interoperability will provide benefit for all the players in the value-chain, especially at the multimedia applications layer, and encourage growth of this market.

This Question is intended to produce deliverables related to study IPTV platforms, including, but not restricted to middleware, applications, content formats and their uses, which will facilitate effective and interoperable use of the IPTV systems. The Question will be the recipient of a number of documents from the IPTV Focus Group and it will assimilate these into its work program with the intention of generating a number of standards (ITU-T Recommendations).

Study Group 13 the lead for NGN in ITU met in April reached final ‘approval’ stage on two Recommendations and consented a number of others, as well as starting discussions on some new work areas. SG13 met concurrently with SGs 19 and 11 as part of the NGN Global Standards Initiative (NGN GSI).

Among inputs to a special ‘futures’ brainstorming session at the meeting were proposals on Mobile IPTV standardization and a “Future Vision beyond NGN”. Mobile IPTV is described as IPTV to mobile and wireless networks. There was discussion on a possible standard that would be neutral in terms of the wireless technology and would cover architecture for NGN, authentication for user mobility and seamless connectivity for mobility, security, and signaling for scalable delivery of content.

The paper “Future Vision beyond NGN” proposed that the future beyond NGN is next generation ubiquitous networking. Study areas for ITU-T and particularly Study Group 13 could be media, identity and so-called ABC (for accounting, billing and charging) processing; open service environment, service and transport control; extending QoS capabilities for bandwidth, security, mobility, personalization and media; supporting a variety of NGN applications including fixed-mobile convergence (FMC), networked IDs, ubiquitous sensor networks (USN), home networking, IPTV etc. The paper also proposed that this work should be more closely linked with protocol development.

Another important document given the first stage approval known as consent defines the service requirements, service features, service architecture, and implementation scenarios of IMS based real-time conversational multimedia services. These include PSTN/ISDN simulation services. When these real-time conversational multimedia services are provided by using an IMS-based service environment, the implementations will use SIP protocol between the Service Support Functions and the Service Control Functions [ITU-T Y.2012] [ITU-T Y.2021]. IMS based NGNs which meet these service requirements will be capable of supporting real-time conversational multimedia services with new service features as well as allowing for new implementation scenarios.

Also consented were documents charting OAM requirements for T-MPLS based networks and QoS control architecture for Ethernet-based IP access networks.

Study Group 19 meeting at the same time consented a document outlining the general requirements for fixed-mobile convergence – a key application in NGN.

Recognizing that satellite systems could be an important part of emerging Next Generation Networks (NGN), an ITU-T Workshop entitled “Satellites in the NGN?” will take place 13 July 2007 in Montreal, Canada. Following the workshop, the third meeting of the Intersector Coordination Group on Satellite Matters (ICG SAT) will take place.

The objectives of the workshop, hosted by ATIS, include examination of the role of satellite systems in NGN, and development of a perspective on current and future NGN standards. Participation is open to all interested parties.

Sessions will give an overview of NGN, examine QoS and QoE (E for experience), IPTV and mobility support, network management and requirements for disaster relief.

The role of the ICG SAT is to monitor and coordinate the work programmes of the relevant Study Groups in ITU-R and ITU-T in relation to the use of satellites. It aims also to draw the attention of the relevant Study Groups to emerging technologies and perform gap analysis to identify new work areas.

Study Group 11 meeting in Geneva, end April has consented three important documents charting protocols for quality of service (QoS) in NGN. The protocols will ensure interoperability between network elements and systems as well as giving service providers the ability to specify rules for specific communication types.

The announcement marks a significant step forward for ITU-T’s NGN work. Protocol development is seen as the final stage of standards development following identification of the requirements, architecture, services etc. The Recommendations are a crucial part of the NGN standards package and a concrete realization of the functional architecture defined in ITU-T Rec. Y.2111 - Resource and admission control functions in Next Generation Networks.

The protocols agreed at the April meeting will guarantee that when a service request is made QoS needs are transmitted, ensuring that each network element provisions the correct level of bandwith and resources to ensure the class of QoS for that particular application. So – for example – more bandwidth can be allocated and guaranteed for IPTV than for voice.

The three ITU-T Recommendations include the specification of the physical entities involved in resource control signalling, the interfaces across which signalling takes place, and the mapping between these entities and interfaces and the corresponding functional entities and reference points in ITU-T Rec. Y.2111. An Appendix provides a further mapping between the interfaces and the protocol specifications which realize those interfaces.

The Recommendations refer to signalling used in different geographical parts of the world: ITU-T Recommendation H.248/Megaco used in for example Japan, COPS used for example in China and Diameter which is used in North America.

Another three protocols in the field of resource control were consented by Study Group 11 earlier in the year.

A call for papers has been issued for the 10th Asia-Pacific Network Operations and Management Symposium (APNOMS 2007).


The event will be held in Sapporo, Japan from October 10 to 12, 2007 with the theme “Managing Next Generation Networks and Services.”

From the call for papers: “Recently, various convergences in wired and wireless networks, and convergence of telecommunications and broadcastings are taking place for ubiquitous multimedia service provisioning. For example, broadband IP/MPLS wired networks are actively converged with IEEE 802.11e wireless LAN, IEEE 802.16 Wireless MAN, 3G/4G wireless cellular networks, and direct multimedia broadcast (DMB) network. For efficient support of service provisioning for ubiquitous multimedia services on the broadband convergence networks, well-designed and implemented network operations and management functions with QoS-guaranteed traffic engineering are essential.”

“In APNOMS 2007, the topics of interest include, but not limited to, network & service management for broadband convergence networks, business operations & management, service-oriented managements (e.g., SLA/SLS, security, billing), management architecture and technologies, various experiences, and recent standardization activities.”

ITU-T will hold a Workshop on Multimedia in NGN, Geneva, 10-11 September.

Multimedia applications and services are migrating towards a single converged user-centric communications network. The “internet of things” represents one of the key challenges for NGN standardization.

This migration, or evolution, has been recognized in ITU-T and a number of initiatives have started for the development of global standards in specific areas like IPTV, GRID, networked aspects of identification (including RFID aspects), sensor networks and more.

An aim of the NGN is to provide the necessary service capabilities to support present and future multimedia applications and services.

This workshop will contribute to the NGN vision of supporting future multimedia services and applications, and will facilitate experience and knowledge sharing between the NGN community, multimedia service and application experts. The various sessions will identify future developments at the service and application level and their impact on NGN capabilities.

The workshop will investigate future trends driven by technology and business needs in the area of multimedia services and applications, including those resulting from fixed-mobile-broadcast convergence.

Study Group 4 has consented a set of Recommendations on data definitions for terminal users of operational support systems. These definitions will allow operators to communicate more efficiently on operational matters, such as service orders and orders about network routing arrangements.

According to developers of the Global Telecommunications Data Dictionary (GTDD) (ITU-T Recommendations M.1401-10), the data definitions use an approach that is different from current conceptual approaches to define data communication interfaces. The GTDD approach will be more intuitive for end-users, in this case the operations staff in telcos.

The data definitions given in the GTDD may be used to develop XML schemas for exchange of data about telecoms networks and services between network operators. The GTDD defines data for end user interfaces and supports data communication to/from management applications.

Experts said that much of the data needed by NGN is defined not only for management but also for the execution of services. Definition of service management is critical for NGN, because it deals with interfaces that will be used by service platforms like IMS. Another use for GTDD is inventory management experts said.

The first steps towards a globally harmonized approach to identity management (IdM) have been taken during a meeting bringing together, for the first time, the world’s key players in the IdM space.

IdM promises to reduce the need for multiple user names and passwords for each service used, while maintaining privacy of personal information. A global IdM solution will help diminish identity theft and fraud. Further, IdM is one of the key enablers for a simplified and secure interaction between customers and services such as e-commerce.

Experts at the meeting concurred that interoperability between existing IdM solutions will provide significant benefits such as increased trust by users of on-line services as well as cybersecurity, reduction of SPAM and seamless “nomadic” roaming between services worldwide.

Abbie Barbir, chairman of the Focus Group on Identity Management (FG IdM): “Our main focus is on how to achieve the common goals of the telecommunication and IdM communities. Nobody can go it alone in this space, an IdM system must have global acceptance. There was a very positive feeling at the meeting that we can achieve this and crucially we saw a great level of participation from all key players.”

The meeting of the FG IdM brought together developers, software vendors, standards forums, manufacturers, telcos, solutions providers and academia from around the world to share their knowledge and coordinate their IdM efforts. Interoperability among solutions so far has been minimal. One conclusion of attendees is that cooperation is crucial and that players cannot exist in isolation. The spirit of the meeting was that everyone will gain by providing an open mechanism that will allow different IdM solutions to communicate even as each IdM solution continues to evolve. Such a “trust metric” does not exist today experts say.

Work will continue online and during Focus Group meetings in April, May, and July. An analysis of what IdM is used for will be followed by a gap analysis between existing IdM frameworks now being developed by industry fora and consortiums. These gaps should be addressed before the interworking and interoperability between the various solutions can be achieved. The aim is to provide the basis for a framework which can then be conveyed to the relevant standard bodies including ITU-T Study Groups. The document will include details on the requirements for the additional functionality needed within next generation networks (NGN).

ITU-T has a long history of innovation in this field, with key work on trusted, interoperable identity framework standards including Recommendation X.509 that today serves as the primary “public key” technical mechanism for communications security across all telecom and internet infrastructures.

Standards that will ease the wide spread rollout of video over IP networks took a step forward in January.

IPTV architecture and requirements, two fundamentally important areas in standards work were progressed at a recent meeting of the ITU-T Focus Group on IPTV. There was general consensus in the meeting that FG IPTV will successfully develop documents which will accelerate introduction of IPTV to the global market. Setting the architecture and requirements in stone allows the rest of the work to continue with greater ease.

Meeting at the Microsoft conference center, Mountain View California, at the invitation of the Alliance for Telecom Industry Standards (ATIS) the group saw a record number of contributions and experts worked often late to keep up with the workload. Nearly 90 documents were dealt with in the fields of architecture and requirements alone.

Malcolm Johnson, newly elected Director of ITU’s Telecommunication Standardization Bureau said in a message he sent to the event: “The excellent cooperation between ITU-T and ATIS is an example of the spirit of cooperation that I believe now pervades in the standards world... From what I have seen there is a great deal to be satisfied by in terms of the progress that FG IPTV has achieved so far.”

In opening comments, ATIS President & CEO Susan Miller shared with the 200 meeting attendees that IPTV is serving as a “change agent” for the industry, and “as both the business case and principal driver for accelerating deployment of the next generation network.” Miller noted that for North American service providers in particular, “IPTV is a critical ingredient to bundled service offerings that encompass television services, mobile services, Internet access, and much more. We have seen in the last decade, enormous investments in broadband, and fiber deployments to the home and to the premise,” said Miller.

Also important a document outlining terms and definitions in the field was created. While seemingly mundane this work is crucially important in ensuring consistency of comprehension in an area where many standards outlining different aspects of IPTV will co-exist.

Further discussion is expected on whether and how to treat the issue of redistribution of content to a point past an IPTV terminal device, and, in particular, how content protection and content management functions can or should apply in a home network environment.

Other issues examined and progressed were accessibility issues for people with disabilities, AV codecs and content format requirements. Output (and other) documents can be seen here.

The next meeting of FG IPTV will be held from 7 to 11 May 2007 in Bled, Slovenia.

ITU and the IEEE will hold a workshop on carrier-class Ethernet, 31 May- 1 June.

Much work has been done in both organisations to progress Ethernet, developed as an enterprise technology, into a carrier service. The event will focus on opportunities for further collaboration.

Long-recognized as the ubiquitous LAN technology, Ethernet is now seeing increased attention as a carrier-grade service. In part this is due to the convenience of being able to simply provide end-to-end service, but also carriers can realize savings both in terms of capital and operational expenditure.

Ethernet services are becoming popular because they allow carriers to offer considerably improved flexibility to customers through a much simpler and lower cost interface. Ethernet allows users to specify exactly how much bandwidth they want between the 10Mbit/s and 1Gbit/s range currently offered. Further, Ethernet provides reduced operation complexity and improved scalability for carriers. And as operators look to NGN and the use of the Internet Protocol (IP), Ethernet is seen as the best fit, especially given the rise of such services as IP VPNs, VLANs and dedicated Internet access.

The event will start with an overview of the standards work from ITU-T and IEEE and will then drill down into detail with sessions focusing on: Ethernet based and Ethernet capable access networks; Ethernet network transport; Ethernet Bridging architecture; Ethernet OAM and management; Ethernet QoS, timing and synchronization. A closing session will bring together reports from all of the session chairs in order to identify the direction of future work.

ITU-T will hold a Workshop on Digital Identity for NGN Geneva, 05 December 2006.

In the last few years, the need for digital identity has risen as a strong driving force behind network architecture design, service provisioning, and content handling, billing and charging. Digital identity is expected to be a powerful tool for users to access unlimited digital resources via a limited number of trusted relationships, and for providers to offer these resources across the different layers of communication systems, administrative domains and even legal boundaries. However, the lack of a common view on digital identity across these different layers has so far resulted in independently developed and therefore often inconsistent identity management frameworks as well as incompatible applications.

Key challenges towards the development of a more consistent approach are to tackle the conflicting requirements of privacy, identification and security. This workshop, a Joint ITU-T/EU IST Daidalos Project Workshop, intends to investigate different approaches, analyze gaps in today’s standards, identify future challenges and find common goals which will provide direction to the work currently being undertaken in the different projects and standards development organizations (SDOs).

A new tool that will give a unique overview of ITU-T’s next generation network (NGN) work has gone live. The NGN Project Management Tool, was developed with the support of a voluntary contribution from Siemens.

Since the work towards standards for NGN is taking place across a number of different ITU-T study groups and other standards development organizations (SDOs) the ability to coordinate and view all NGN work in one place will be invaluable to the swift and efficient publication of NGN specifications.

Essentially a repository of information from ITU and other SDOs, the system was asked for by members of the various Study Groups working on NGN. Key will be the ability to keep track of the latest versions of Recommendations and provide detailed information for experts and summaries for management.

ITU-T will host the annual Broadband Europe conference 11-14 Dec 2006.

BBEurope is an annual event which was initiated by the FP6-BREAD-project (broadband for all in Europe: a multi-disciplinary approach), part of the "BroadBand for All"-strategic objective of the European Commission.

Peter Van Daele, Project Leader BREAD: “The concept of “Broadband For All” refers to a situation in which broadband is not only available to every citizen, but is actually used by all of them. In that respect it is a more demanding concept than the traditional universal service obligation in telephony, which merely stipulates the availability, at certain conditions, of a given service. The usage of information and communication technologies via broadband infrastructures by all citizens is a policy objective because it is considered to be a key component of transforming Europe into a knowledge-based society, thus enhancing economic growth and increasing employment.”

The BREAD project has amongst its objectives to develop a holistic vision encompassing technical, as well as economical and regulatory aspects. Another important aspect is of identifying roadblocks on European, national/regional level and share visions and best practices on national level to EU level.

BBEurope brings together on an international level all the BroadBand players, researchers, service providers, content providers, operators, manufacturers, policy makers, standardisation bodies, professional organisations.

A diverse agenda will cover topics including NGN, IPTV, wireless access, powerline, security, QoS, and broadband in rural areas. The event will conclude with a panel discussion titled: Future Perspectives in Broadband. A ‘full preliminary’ programme is available from the event’s website, with the call for papers ending November 10 when a programme committee will make a final selection of the papers.

John MacDonald, a member of the ITU team that created the new VDSL 2 standard, will take part in an upcoming Webinar on this topic, Tuesday, November 21. The Webinar, the second on the topic that ITU has contributed to, will outline what VDSL2 is, which are its competitive differentiators and benefits, and how it allows service providers to compete with cable and satellite operators - by enabling the delivery of enhanced voice, video and data services over a standard copper telephone cable.

ADSL (Asymmetric Digital Subscriber Line) is a product of ITU-T, ITU’s standardization arm, and is the world's most widely deployed broadband access technology. It has enhanced users' experience of the Internet, provided access to digitized content, and fuelled the delivery of streaming video and the development of online gaming by offering downstream data rates of up to 8 Mbit/s. Today, service providers must ensure their DSL offerings can compete against other market options from cable operators. One way to do so, is by offering services over VDSL2 (ITU-T Recommendation G.993.2) - very high-speed DSL - a new version of DSL, which gives service providers the ability to deliver even higher bandwidth and more enhanced services to consumer and business customers.

Delivering up to 100 Mbit/s both up and downstream, a tenfold increase over ADSL (Asymmetric DSL) VDSL2 provides for so-called fiber-extension, bringing fiber-like bandwidth to premises not directly connected to the fiber optic segment of a telecom company’s network. By deploying VDSL2 operators expect to be able to offer services such as high-definition TV (HDTV), video-on-demand, videoconferencing, high-speed Internet access, and advanced voice services. Importantly VDSL 2 offers carriers a solution that is interoperable with the DSL equipment many already have in place. In addition, VDSL 2 will work with both legacy ATM networks and next generation IP-based networks.

With the second meeting of the IPTV Focus Group (FG IPTV) seeing a record number of participants and contributions, experts have declared satisfaction that work towards a set of standards for IPTV is well on track.

A recent report from industry analyst Gartner says that the number of households around the world subscribing to IPTV services offered by telecom carriers will reach 48.8 million in 2010. Buoyed by new service launches, IPTV subscribers will more than double in 2007 from an expected 6.4 million in 2006 to 13.3 million according to Gartner.

Experts agree that it is imperative that standards needs are met if these impressive figures are to be achieved.

A key achievement at the FG IPTV meeting in Korea was progress towards an standardized IPTV architecture: The group agreed that IPTV architecture shall allow for both NGN and non-NGN approaches to IPTV, and within the NGN-approach, include both IMS and non-IMS based approaches.

Ghassem Koleyni, chair of the group: “I am particularly happy that we have achieved so much progress in Working Group 1 (service requirements and architecture). The level of participation in this group is growing and progress is overall good. But requirements and architecture are of such fundamental importance that getting a fix on these points, at this stage, is very satisfying. In order to gain momentum here we will convene an electronic meeting looking specifically at requirements and architecture, 18-21 December.”

The Korea meeting agreed on the following definition of IPTV: “IPTV is defined as multimedia services such as television/video/ audio/text/graphics/data delivered over IP based networks managed to provide the required level of QoS/QoE, security, interactivity and reliability.”

The next face-to-face meeting of the FG IPTV is scheduled for 22-26 January 2007 at the Microsoft facilities , Mountain View, California, USA (Silicon Valley) at the kind invitation of Alliance for Telecommunications Industry Solutions (ATIS).

The FG IPTV meeting was preceded by an ITU-T workshop. The event attended by over 400 and held in Seoul provided a view and examination of IPTV standardization, political and regulatory aspects, business models and various case studies as well as technical developments and service provider’s operational aspects. A roundtable discussion at the event concluded that global standardisation and interoperability are key for further development of IPTV worldwide. Other issues that might be further discussed at an international level, according to the roundtable’s twenty participants, include digital rights management (DRM).

ITU-T Recommendation Y.2111, a new standard emerging from the July NGN-GSI meetings addresses a key area of concern in NGN, the ability to offer end-to-end QoS. Crucially it also addresses the need to be able to differentiate multiple services running over the same network.

The Recommendation deals with resource and admission control functions (RACF) which will help enable operators to guarantee end-to-end quality for multimedia services in NGN, for example VoIP and IPTV. Key to the approach is the ability for an operator to specify rules to specific communication types in order that they can better allocate network resources.

With most IP networks today operating under a best-effort system, network congestion can significantly undermine the quality and reliability of more advanced multimedia applications. RACF meets the demand for more intelligent control of packet-based network infrastructures.

The Recommendation defines the related requirements and functional architecture covering aspects such as resource reservation, admission control and gate control, Network Address Port Translation (NAPT) and firewall control, and Network Address Translator (NAT) traversal.

 

 

Monday, October 02, 2006 9:50:01 AM (W. Europe Standard Time, UTC+01:00)  #     | 

Recommendation Y.2012 consented at the July SG 13 meeting describes the functional architecture of the NGN.

The NGN architecture described supports the delivery of services such as multimedia services, conversational services, and content delivery services (eg video streaming and broadcasting).

NGN functional architecture shall incorporate the following principles according to the Rec.:

·          Support for multiple access technologies: The NGN functional architecture shall offer the configuration flexibility needed to support multiple access technologies.

·          Distributed control: This will enable adaptation to the distributed processing nature of packet-based networks and support location transparency for distributed computing.

·          Open control: The network control interface should be open to support service creation, service updating, and incorporation of service logic provision by third parties.

·          Independent service provisioning: The service provisioning process should be separated from transport network operation by using the above-mentioned distributed, open control mechanism. This is intended to promote a competitive environment for NGN development in order to speed up the provision of diversified NGN services.

·          Support for services in a converged network: This is needed to generate flexible, easy-to-use multimedia services, by tapping the technical potential of the converged, fixed-mobile functional architecture of the NGN.

·          Enhanced security and protection: This is the basic principle of an open architecture. It is imperative to protect the network infrastructure by providing mechanisms for security and survivability in the relevant layers.

·          Functional entities should incorporate the following principles:

o         Functional entities may not be distributed over multiple physical units but may have multiple instances.

o         Functional entities have no direct relationship with the layered architecture.  However, similar entities may be located in different logical layers.

 
Along with a new architecture, NGN will bring an additional level of complexity beyond that of existing networks. In particular, support for multiple access technologies and mobility results in the need to support a wide variety of network configurations. Some examples of configurations are provided to provide put in context the architecture description.

Although the scope of the Rec. is primarily NGN architecture, it also takes into account legacy PSTN/ISDN terminals and/or interworking with the PSTN/ISDN which is clearly is an important consideration with respect to NGN deployment. Three additional Recommendations were consented in this area Y.2031, Y.2261 and Y.2271.

One of the most important ITU-T Recommendations emerging from the SG 13 meeting specifies the high level requirements and associated capabilities for NGN. Defining requirements is a fundamental and essential part of the standards making process. The document outlines the basic foundations necessary for NGN work to progress and, in particular, for supporting the service objectives of NGN Release 1.

So, for example: “The NGN transport stratum [Y.2012] shall use the IP protocol for general, ubiquitous, and global public connectivity. The IP protocol may be carried over various underlying transport technologies in the access and core portions of the transport stratum (eg. xDSL, ATM, MPLS, Frame Relay, OTN) according to the operator’s environment.”

Aligned with the general goals and objectives captured in the ITU’s definition of NGN published in Recommendation Y.2001 the proposed Recommendation (Y.2201), as well as other documents finalized in July, is an updated version of an output from the Focus Group on NGN (FG-NGN), November 2005.

Experts say that it is important to note that NGN standards authors will have used the requirements text agreed in November 2004 as a basis for their work. Publication as an ITU-T Recommendation will give legal (normative) status and has enabled some general refinement as well as updating particularly in the area of regulatory requirements.

ITU-T Study Groups meeting under the auspices of the NGN Global Standards Initiative (NGN-GSI), July, finalized a substantial body of work. Sixteen new standards went into the final stages of the ITU approval process in areas including requirements, architecture, QoS and security. Around 650 documents were considered by the lead SG on NGN, Study Group 13, alone. Study Group management reported high levels of participation and good progress.

Two rather fundamental documents describing requirements for NGN and describing the functional architecture of the NGN will be published as ITU-T Recommendations after formal approval. Also, QoS, a crucial element as networks move to an environment inherently more susceptible to delay, interference etc. was a key focus, one new Recommendation was consented in this field.

Experts also point to the importance of a Recommendation (ITU-T Rec. Y.2021) describing how the IP multimedia subsystem (IMS) as specified by the 3rd Generation Partnership Project (3GPP) and the 3rd Generation Partnership Project 2 (3GPP2) can be used in the NGN context. A Rec. from Study Group 19 on mobility management was also highlighted, see story here.

ITU-T is hosting a workshop NGN and Grids in collaboration with the Open Grid Forum (OGF) in Geneva, 23-24 October 2006.

Grid computing enables organizations to pool IT resources across departmental and organizational boundaries in a secure, highly efficient manner in order to solve massive computational problems.

Next generation networks (NGN) offer increased quality and service features for users, independent of the underlying transport technology. ITU-T’s Global Standards Initiative on Next Generation Network (NGN-GSI) is well under way and is responding to urgent market needs for global NGN standards.

The workshop will explore how Grids will work in an NGN environment by bringing together experts from both communities.

The telco community is eyeing Grid development with interest. Telcos could use grids internally, for billing and simulations for example but new revenue streams can be foreseen in areas such as managed grid services.

One panel discussion and Q&A will pose the question: “What can Grids do for Telcos and what can Telcos do for Grids?” Other panel discussions will examine NGN management and security.

From a telecoms perspective there are some challenges such as QoS, how to control the network, how to manage dynamic provisioning and how to provide collision-free addresses (IPv4 <-> NAT). It is expected that all of these topics and more will be addressed.

A key result of the event will be a gap analysis of standards in the field and a better understanding of how grids can be catered for in ITU-T’s NGN Release 2. An action plan outlining what work needs to be done, and where can then be developed.

The ITU-T Study Group dealing with mobile telecommunication and fixed mobile convergence together with the lead Study Group on NGN has published a standard that describes what is needed to give users the ability to access the same set of services irrespective of change in location.

Mobility is a crucial part of the service capabilities within the next generation network (NGN) concept. The ITU-T Recommendation notes: “… with the massive growth in the number of users and the continuing deployment of heterogeneous systems the demand to provide seamless services to the NGN users gets stronger…”.

The Recommendation - Q.1706 - describes the requirements for providing ‘mobility management’, that is the set of functions used to provide mobility. These functions include authentication, authorization, location updating, paging and download of user information. The aim of this work is to build on the current mechanisms in cellular telephone systems and the internet and to move toward homogeneity in handling mobility across the converging telecommunication and computing environments.

The next step for SG 19 will be a Recommendation describing the framework for achieving mobility management based on these requirements. SG management suggests that this work is progressing well and will probably be achieved in time for the next round of approvals targeted to be initiated at a meeting in April 2007.

SG 19 also consented a Recommendation that charts further detail in the evolution within the IMT-2000 Family member using an ANSI-41 core network with cdma2000 access network. Recommendation Q.1742.5 references 3GPP2 work.

Study Group 13 will publish a Recommendation that acts as an umbrella to progress work on all aspects of multiprotocol label switching (MPLS) management. 

MPLS is seen as an important way to simplify traffic engineering in NGN. ITU-T Recommendation Y.1714 provides a framework for management and operation administration maintenance (OAM) in MPLS. OAM mechanisms facilitate network operation and troubleshooting. Standards-based OAM features that will allow for interoperability between different vendors are seen as a requirement for carriers adopting MPLS.

Referring to the telecommunication management network (TMN) model developed by ITU-T’s Study Group 4, the Recommendation’s scope is limited to those components and interfaces that interface between network elements (user and control plane), and between network elements and element management system (EMS) and network management system (NMS).

Introduction

At the kind invitation of the Tanzania Communications Regulatory Authority (TCRA), the International Telecommunications Union - Standardization Bureau (ITU-T) and the International Telecommunication Union - Development Bureau (ITU-D) are jointly organizing a Workshop on “Next Generation Networks” which will take place from 3-5 October 2006 inclusive, at the Markham Suites Hotels, Dar-Es-Salaam, in the United Republic of Tanzania.

The objectives of the seminar are twofold: first, to discuss the current trends, status and future evolution of Next Generation Networks technology and standardization, as being addressed by the ITU-T and share the experiences of NGN design, development and deployment. Central to these are: what areas of technology innovation hold the greatest promise for NGNs; what are the most innovative applications and services possible with NGNs? To this effect, issues revolving around NGN architecture, NGN technology and quality of service requirements, as well as evolution will be explored. Second, as NGNs are a major departure from the network today - these developments will likely change the ways of the telecommunication sector operates, NGN regulatory and policy issues for developing countries to exploit its full potential for development will also be discussed.

ITU-T’s work on IPTV took a significant step forward following a meeting Geneva, July 10-14.

IPTV is being explored by media companies and service providers around the world as a way to add value to their existing offerings, and globally accepted standards are seen as essential in order that – for example – a broadcaster in one part of the world can easily distribute content in another.

The meeting of the IPTV Focus Group (FG IPTV) attracted over 150 delegates from the world’s key ICT companies, over 100 input documents were considered, and the first drafts of various output documents agreed. All documents can be viewed on the group’s webpage.

A key output document drafted at the meeting shows the requirements for standardization in IPTV. Establishing this list is an essential part of the standards making process. Also dealt with by the group, and equally as important is outlining what standards already exist.

The meeting approved the establishment of six working groups:

  • Architecture and Requirements
  • QoS and Performance Aspects
  • Service Security and Contents Protection
  • IPTV Network Control
  • End Systems and Interoperability Aspects
  • Middleware, Application and Content Platforms
The next FG IPTV meeting will take place in Busan, Korea, 16-20 October, 2006.

ITU-T’s Study Group 12 has consented a new Recommendation (Y.1542) that gives the groundwork for service providers to realize end-to-end network performance for services like VoIP and IPTV. The work goes some way to satisfying a key challenge for next generation networks (NGN), which need to provide QoS across multiple network operators, and in some cases, unusual topologies and distances.

The Recommendation points out that compared to the circuit switched environment, networks based on: “…IP pose distinctly different challenges for planning and achieving the end-to-end performance levels necessary to adequately support the wide array of user applications.”

Complementary work was completed previously in the form of Recommendations Y.1540 and Y.1541 which give network performance objectives for IP-based services, and QoS classes with more stringent packet loss performance, needed for example for commercial video applications.  

Using the QoS classes defined in Y.1541, the new Recommendation explores different approaches to realize end-to-end QoS depending on the type of service. Each class is designed to support a group of applications, VoIP, or IPTV for example.

One key area to be addressed is the development of an end-to-end QoS signalling mechanism that will allow the deployment of such classes.
 
The new Recommendation, Y.1542, is a framework towards a methodology for satisfying end-to-end objectives and gives guidance intended to accelerate the planning, deployment and management of networks and systems that can interoperate with a goal of supporting the end-to-end performance objectives detailed in Y.1541.

The guidance provided in Y.1542 should "...facilitate network design and operation capable of nearly always meeting the desired levels of performance". According to experts it will also act as a contribution by SG12 to the ITU-T's Joint Coordination Activity on NGN.

ITU-T Recommendation M.3343 consented at the Beijing meeting of Study Group 4 outlines the requirements and protocol neutral information model necessary to communicate trouble tickets in a multi-service provider NGN environment.

NGN according to the Recommendation introduces new reporting needs to address new service types expected.

The Recommendation describes a trouble in a communications network as a problem that has an adverse effect on the quality of service perceived by network users. Management of trouble tickets is necessary to ensure that they receive attention and that the trouble is cleared to restore the service.

At the time of a trouble, a network may have been inter-working with another network to provide a service. Therefore a standardized way of exchanging trouble management information between management systems across interfaces is necessary.

Study Group 4 saw the consent of a Recommendation (M.3342) which provides the means to document service level agreements (SLA) between a service customer and a service provider.

The Rec. takes into account the fact that NGN demands QoS guarantees for services. SLAs are considered an effective way of solving the problems of QoS guarantee between customers and providers. The Recommendation describes the detailed classification of SLA content, provides guidelines and instructions for the definition and composition of ‘SLA representation templates’ in order to manage QoS and service guarantees more effectively. It also includes instructions on how to complete the templates.

The NGN Management Focus Group (NGNMFG) is seeking more input from service providers and network operators in order to build a more accurate roadmap of needs and existing specifications for NGN management. The group presenting version 2 of its roadmap at the May meeting of Study Group 4, in Beijing, changed its terms of reference to reflect the need.

While roadmap V1 identified NGN management specifications from ITU-T as well as other standards making organizations, V2 provides gap analysis and pinpoints areas that can benefit from better harmonization. Recognizing a gap in managing new functions tying the NGN transport stratum to the service stratum, V2 sees the addition of management of IMS (IP multimedia subsystem) and NGN transport technologies like ASON (automatic switched optical network) and Ethernet.

The roadmap can be found here.

ITU-T is hosting a workshop NGN and Grids in collaboration with the Global Grid Forum (GGF) in Geneva, 23-24 October 2006.

ITU-T’s Global Standards Initiative on Next Generation Network (NGN-GSI) is well under way and is responding to urgent market needs for global NGN standards. NGN offers increased quality and service features for users, independent of the underlying transport technology.

Grids have been widely used in the scientific community. Increasingly, Grids are being deployed within commercial settings. The Global Grid Forum is actively reaching out to communities such as the Telco community to advance Grid adoption, interoperability and scalability. Different scenarios for Telcos can be envisioned: Telcos may 1) specialize in network SLAs that are optimally suited to Grids; 2) use Grids for their IT internal needs; and/or 3) offer Grids as a managed service to customers.

The Security Assertion Markup Language (SAML) and Extensible Access Control Markup Language (XACML) authored by OASIS (Organization for the Advancement of Structured Information Standards) have been consented as internationally recognised ITU-T Recommendations. The announcement is the first result of the formal relationship between the standardization sector of ITU and OASIS.

The standards (ITU-T Recommendations X.1141 (SAML) and X.1142 (XACML)) address the concern of how to allow safe single sign-on, a system that enables a user to authenticate once and gain access to the resources of multiple software systems. While solutions existed in this space, all were proprietary, and therefore not addressing the problem on a global level.

SAML and XACML are designed to control access to devices and applications on a network. The need for standards in this area has become more of an issue as business networks increasingly use the public Internet.

SAML addresses authentication and provides a mechanism for transferring authentication and authorization decisions between cooperating entities, XACML leverages this information to determine access to resources by focusing on the mechanism for arriving at those authorization decisions.

An additional feature of SAML is that it allows organizations to communicate information without any change to their own internal security architectures.

SG16 completed work on a new scalable voice codec - G729.1 - that will significantly improve voice quality in VoIP calls by offering wideband quality. Wideband telephony gives more natural sounding voice and greatly improves intelligibility and listening comfort.

G.729.1 extends the ITU-T G.729 speech coding standard widely used in VoIP systems and is fully interoperable with it. It will allow smooth transition from narrow band (300-3400 Hz) "PSTN" quality telephony to high quality wideband (50-7000Hz) telephony over IP and efficient deployment in existing infrastructures.

G.729.1 can operate at 12 bit rates from 32 kbit/s down to 8 kbit/s with wideband quality above 14kbit/s to dynamically provide the optimum voice quality according to service and network constraints: The bit rate can be adjusted "on-the-fly" during a call by simple truncation of the "embedded" bitstream at any point of the communication chain such as gateways or other devices combining multiple data streams. This highly flexible bit rate adaptation will avoid network congestion and the dropping of packets that severely impair the overall quality.

A new standard extending support of a key communications tool for the deaf and hard of hearing to IP-based networks was consented at a recent meeting of ITU-T’s Study Group 16. The continued support of textphones (TTYs) as operators increasingly shift to IP is important for the many thousands of users of these systems.

The announcement marks a key milestone in the development of what ITU terms Total Conversation, that is the convergence of voice, video and text telephony.

The new standard known as ITU-T Recommendation V.151 relates to text over IP (ToIP). ToIP is the transport of real-time text over IP networks. It differs from instant messaging in that ToIP systems transmit bi-directionally, one character at a time. This gives the user the feel of real-time communication, just like voice or video systems that transport streaming media over IP.

ToIP services are available using a legacy textphone (TTY) which has long been the preferred tool of the deaf and hard of hearing, an enabled IP phone or a PC-based client.

V.151 has an important role to play in the protection of text quality when transported through IP networks, also offering the potential to enable communication between earlier incompatible textphones from different regions.

ITU will take the lead in international standardization for IPTV with the announcement that it is to form a Focus Group on IPTV (IPTV FG).

The announcement, while acknowledging that standards work is ongoing in many different places, including ITU, is a reaction to an industry call for ITU to push forward and coordinate global standardization effort in the field.

IPTV is a system where a digital television service is delivered to consumers using the Internet protocol over a broadband connection. It will help pave the way for players, many of whom are already moving to IP-based NGN infrastructure, to offer a triple-play of video, voice and data.

Standards are necessary in order to give service providers, whether traditional broadcasters, ISPs or telecoms service providers, control over their platforms and their offerings. Standards here will encourage innovation, help mask the complexity of services, guarantee QoS, ensure interoperability and ultimately help players remain competitive.

The mission of IPTV FG is to coordinate and promote the development of global IPTV standards taking into account the existing work of the ITU study groups as well as SDOs, fora and consortia.

The group was launched following a decision taken at a public consultation meeting attended by around 120 experts from the world’s ICT companies. Attendees agreed that all players in the IPTV value chain will benefit from worldwide standards, that there is a lot of work to be done and that rapid progress is necessary in order to avoid market fragmentation. The Focus Group mechanism was seen as the most effective way of addressing this. Inputs to the meeting as well as a webcast can be found here.

Houlin Zhao, Director of the Telecommunication Standardization Bureau of ITU: “We have seen a desire to expedite and accelerate a global focus on standards for IPTV. There has been extraordinary consensus that ITU must lead this work and I am pleased that – again - ITU is seen as the right place to develop and harmonize this international standardization work, as well as identify and help fill gaps where there is still a standardization need.”

Bilel Jamoussi, Director Strategic Standards, Nortel, said: “Industry applauds ITU’s initiative to create this Focus Group and will contribute to its success.”

The FG will build upon existing work. Its scope will include architecture and requirements, QoS, security, network and control aspects, end system aspects – terminals etc., interoperability, middleware and application platforms.

John McDonald, a member of the ITU team that created the new VDSL 2 standard, will take part in an upcoming Webinar on this topic, Monday, April 03. The Webinar hosted by Light Reading will look at this development and explore the significance and implications of the new standard for both operators and the enormous installed base of DSL subscribers.

ITU’s new VDSL 2 (Very High-Speed DSL 2) standard (ITU-T Recommendation G.993.2) delivers up to 100 Mbit/s both up and downstream, a tenfold increase over ADSL (Asymmetric DSL). By doing so, it provides for so-called fiber-extension, bringing fiber-like bandwidth to premises not directly connected to the fiber optic segment of a telecom company’s network.

VDSL 2 will allow operators to compete with cable and satellite providers by offering services such as high-definition TV (HDTV), video-on-demand, videoconferencing, high-speed Internet access, and advanced voice services, over a standard copper telephone cable.

As well as addressing fast-growing consumer demand for high-speed multimedia services, VDSL 2 offers carriers a solution that is interoperable with the DSL equipment many already have in place, expediting migration of customers to new VDSL 2-based products. In addition, VDSL 2 will work with both legacy ATM networks and next generation IP-based networks.

The Director of ITU's Telecommunication Standardization Bureau (TSB), Houlin Zhao, has convened a meeting 4-5 April 2006 in Geneva to explore standardization in Internet Protocol Television (IPTV).

IPTV rollout is expected to grow at a brisk pace in the coming years. 

Many of the world's major telecommunications providers are exploring IPTV as a new service. It is increasingly seen by operators as an important part of a triple play package of voice, video and data services. Standardization is key if service providers are to offer good quality, and provide the value-adds such as video on demand services which will inevitably drive the market. 

Zhao is convinced that standardization in the field is an urgent need. “IPTV is becoming an increasingly important service in the market, and more and more ITU-T Members have said that they are facing challenges from technical as well as regulatory issues,” said Zhao. “We have received a number of proposals to strengthen our work on IPTV standardization in order to meet the needs of market players and users. I encourage ITU members and ITU partners to provide contributions and to participate at the meeting. I am confident that this will be a very productive and successful meeting.”

The meeting will examine; the situation and challenges of IPTV service at the national level; the situation and challenges of IPTV service at the regional/global levels; the actions and development of IPTV-related service by SDOs; technical and regulatory challenges and the ITU’s role and expected actions in IPTV standardization.

Study Group 15 has consented a Recommendation that will address a key concern in the evolution to next generation networks (NGN).

With the proposed move to packet switched networks, carriers, mobile operators and system integrators all have a need to support time-division multiplexing (TDM) over packet networks. TDM, experts say, today forms all of the transmission network and a good part of the access network.

The role of this Rec - G.8261 - is to outline the requirements for the support of a crucial part of TDM's operation in packet networks. The Recommendation's authors say that without proper synchronization, applications such as mobile telephony simply will not work.

G.8261 analyses synchronization aspects in packet networks, with particular focus on the Ethernet, and outlines the minimum requirements for the synchronization function of network elements. In particular it focuses on the transport of synchronization information required for the transport of TDM signals over packet networks. The transport of SDH signals is for further study.

January saw a gathering of hundreds of NGN experts in Geneva for the first NGN-GSI (global standards initiative) event. Good progress was reported in several key areas particularly in the important area of functional architecture and requirements for resource and admission control functions (RACF) in NGNs. The Recommendation covering RACF is said to be stable and is expected to be consented at the July GSI event.

The January event comprised three full Study Group meetings (11, 13 and 19). Experts from various other Study Groups were in attendance for this first meeting of the GSI following its launch in November, 2005.

Study Group 13, the lead for NGN work, alone saw over 250 contributions, many a result of the work of the Focus Group on NGN. SG 13 saw three new Recommendations consented, see separate stories (Y.1731, Y.1452, Y.1453).

Study Group 11 reported that 50 contributions were received and launched work on an NGN Protocol Set. According to SG documents ITU-T NGN-Protocol Set 1 will define protocols for the support of:

· Network to Network Interface (NNI) session control;

· User to network Interface (UNI) session control;

· Resource Control Interfaces;

· Network Attachment Interfaces.

Protocol Set 1 is targeted for completion by the end of 2006.

The chair of Study Group 19 reported good progress in the area of FMC (fixed-mobile convergence).  

It is expected that many other of the outputs of the Focus Group on NGN will be consented at this July meeting. Among them will be a Recommendation dealing with performance, management and measurement, another key area in NGN. See the work programmes for the various Study Groups involved in NGN for a full list.

Study Group 13 has consented a new Recommendation that will give support for a widely deployed network technology in IP-based NGNs.

The Recommendation Y.1453 addresses required functions for network interworking between time division multiplexing (TDM) and IP networks.

TDM is a way to transmit multiple subscribers’ calls along the same transmission medium at the same time. Given that is a very widely used technology in existing telecommunications networks its continued support in NGN is imperative.

Y.1453 addresses "user plane internetworking mechanisms, connection multiplexing and procedures (for interworking)".

Study Group 13 will start work on a new topic (Question) relating to commercial off-the-shelf software (COTS).

COTS solutions are seen as an efficient way to reduce operating costs, but a lack of standards has kept costs high for licensing, adapting and integrating these components.

The title of the new Question will be Requirements and framework for enabling COTS components in an open environment. The aim is to outline the open interfaces and standards required to deploy COTS solutions in NGNs.

According to the text of the Question: “Guidance is required to ensure that COTS components will allow for creation of open and integrated communications platforms consistent with open (public and non-proprietary) standards  such that they will accelerate deployment of NGN infrastructure and services. It is necessary to define a common approach that helps to navigate through the appropriate interfaces and options to deliver an open and integrated communications platform using these standards.”

The Question was set up following a proposal from the Focus Group, The Open Communications Architecture Forum (OCAF). A Rapporteur, Johannes Prade, has been provisionally appointed to lead this work.

A review by the Telecommunication Standardization Advisory Group (TSAG) is necessary to complete the formal approval of the Question at the next Study Group 13 meeting in July 2006, but work in the area is ongoing and will continue as normal.

At the same meeting of SG 13, OCAF submitted two draft Recommendations, The carrier grade open environment reference model and Carrier Grade Open Environment Components. It is expected that these will be sent for consent at SG 13’s next meeting.

A new ITU-T standard (Recommendation) will allow operators offering Ethernet services to use operations, administration, and maintenance (OAM) mechanisms to facilitate network operation and troubleshooting.

Given that performance management has been cited as a major concern of operators looking at Ethernet as an end-to-end solution, and that OAM features are not standard in Ethernet, it is seen as crucial to provide this facility. Standards-based OAM features that will allow for interoperability between different vendors are seen as a requirement for carriers adopting Ethernet on a wide scale. Experts say that operator deployments may start in 2007.

Ethernet services are becoming popular because they allow carriers to offer considerably improved flexibility to customers through a much simpler and lower cost interface. Ethernet allows users to specify exactly how much bandwidth they want between the 10Mbit/s and 1Gbit/s range currently offered. Further, Ethernet provides reduced operation complexity and improved scalability for carriers.

And as operators look to NGN and the use of the Internet Protocol (IP), Ethernet is seen as the best fit, especially given the rise of such services as IP VPNs, VLANs and dedicated Internet access. Equally this OAM functionality may be deployed in a local area network (LAN).

The ITU-T Recommendation, Y.1731 consented at the recent meeting of Study Group 13, identifies the OAM functions which are needed to allow fault management (fault localization, defect detection, etc.) and performance monitoring (error counts, delay measurement, etc.) in an Ethernet network. With regards to performance monitoring, the Recommendation only addresses point to point connectivity today, says Gilles Joncour, ITU-T Rapporteur for the Recommendation, (multi)point to multipoint will be the next step.

Joncour gives some more detail: ‘’Y.1731 also specifies the so called OAM PDUs (protocol data units) which constitute the payload of the Ethernet OAM frames. The content (fields) of the PDUs vary according to the function(s) they correspond to. Y.1731 does not specify the processes associated to the sending, reception and analysis (of the content) of the OAM frames/PDUs. This will be part of another Recommendation (G.8021), from Study Group 15. Y.1731 specifies methods for measuring sample values of parameters identified for monitoring the performance of Ethernet networks. It does not deal with the integration of those values over a period of time and the use of such results, when applicable for defect detection. This will also be done in G.8021.”

Recommendation Y.1713 gives user-plane OAM functionality in Ethernet networks. The architectural basis for this Recommendation is the Ethernet specification G.8010. A previous Recommendation Y.1730 served as a prelude to Y.1731 outlining the OAM requirements of operators. Joncour says that Y.1731 was developed in close collaboration with the Institute of Electrical and Electronics Engineers (IEEE) group 802.1. This group is also preparing a standard (802.1ag - Connectivity Fault Management) devoted to Ethernet OAM aspects. IEEE 802.1ag defines a subset of the functions/PDUs described in Y.1731. Regular communications between the two groups ensured alignment of the description of the common features.

With the next phase of ITU-T's work on next generation networks (NGN) underway a new webpage as been unveiled giving access to a variety of NGN resources.

The new page will act as a portal for those people participating in NGN study but also to those new to NGN. Features include a live news feed, a short introduction to NGN, links to official documents, the Release 1 set of NGN specifications, presentations and important dates for your calendar.  

An upcoming feature will be an NGN Roadmap, that will provide an overview of the NGN work going on across the standardization world. Essentially, it will act as a repository of NGN information from ITU and other SDOs. A key feature of the tool will be the ability to track work progress and see the latest versions of documents.

The announcement (18 November) that ITU’s Focus Group on NGN (FGNGN) has completed work on the first set of standards for next generation networks (NGN) marks a significant step towards a fundamental reworking of the world’s information and communications technologies networks. With NGN, network operators hope to replicate the level of service and reliability that customers have come to expect in telecommunication systems across all ICT networks.

The milestone reached with the launch of the Release 1 set of specifications has been achieved in a very short time by members of ITU’s Focus Group on NGN (FGNGN). FGNGN is made up of representatives of the world’s telecoms service and network providers, manufacturers and governments.

Telecoms companies around the world are starting to make the move from the traditional circuit switched networks that have essentially been in place since the earliest days of telecommunications to an Internet Protocol (IP) based system that will create cost efficiencies and allow a much greater level of diversity for service providers. Release 1 will serve as an invaluable tool to facilitate this rollout.

Contained within the 900 pages of ‘deliverables’ are some of the high-level architecture and frameworks for NGN. ITU’s next phase of NGN work – to be called the NGN-GSI (for global standards initiative) - will focus on the detailed protocols necessary to offer the wide range of services expected in NGN. It is also expected that the GSI will aim to harmonize different approaches to NGN architecture in different parts of the world.

Houlin Zhao, Director of the Telecommunication Standardization Bureau, ITU said: “Industry is backing NGN to the tune of billions of dollars. And ITU is very proud that the world’s manufacturers of telecoms equipment, network and service providers and administrations have entrusted us with this work. They understand that global standards will stimulate innovation and superior technology and enable interoperability, protecting current and future investment. ITU is the only body in the world that will be able to offer the necessary convergence between different NGN platforms on a global basis if they emerge.”

Since extending the reliability of telecoms networks into Internet Protocol based systems is key to the success of NGN, quality of service (QoS) specifications have been a strong focus of NGN work. Additionally, security aspects, universal access and the separation of services from the underlying network have been important topics covered.

The NGN-GSI will build on the momentum generated over the past year. The period 2004-2005 has seen meetings and workshops progressing work on NGN around the world. Participation in and contributions to this work are continuing to increase.

The next phase of ITU-T NGN work will see a significant re-organization of work schedules to ensure that experts from different Study Groups are able to meet at the same time. The meeting schedule has also been designed to maintain the brisk pace established during the first phase of the NGN work, and to meet members’ demands.

Three new Recommendations related to IP Performance have been consented by ITU-T's Study Group 12.

G.1030 - provides a framework of tools to estimate end-to-end IP network performance for some user applications. User perception of application performance in packet networks is dependent on many factors, including network end-to-end performance, performance of terminals and other devices beyond the purview of the network operator. The application’s dependency on the communications network, and the user’s task and the extent of user interaction with the application need also to be taken into account.

All these factors are used to estimate end-to-end performance levels. At this stage, the framework includes a perceptual model for web browsing. Future versions will focus on multimedia conferencing and other applications. The Recommendation is designed to be helpful for people designing networks, enabling them to know what applications can be realistically supported. 

G.1040 - defines a new performance metric in IP networks for short transactions, such as trading of stocks, automated banking, and credit card point of sale transactions. The nature of such exchanges is that they need to be quick and reliable.

This Recommendation gives the ability for the network provider to either flag a problem based on their network measurements interpreted with this metric, or to say that – if a problem exists – it isn’t attributable to the network. The Recommendation allows the network service provider to see how much of the transaction time can be attributed to the network. The metric can also be useful in drawing up service level agreements.

G.1050 - addresses Network Model for Evaluating Multimedia Transmission Performance Over Internet Protocol. The need for such a model is driven by new challenges for multimedia applications in IP. Impairments that in typical data transfers are of little consequence may be much more serious in video or VoIP for example. The model is based on statistical models of a broad range of known deployed network configurations. This way a manufacturer of networking testing solutions can avoid speculation in configuring test scenarios.

A roadmap identifying NGN management specifications has been published on the ITU-T SG 4 website.

The roadmap will provide an insight into how NGN management will differ from the management of traditional telecommunication. And as specifications are added this picture will become clearer, experts said.

The NGN Management Specification Roadmap is an output of the NGN Management Focus Group, a group sponsored by ITU-T SG 4. The document identifies the various existing, or work-in-progress specifications relevant to NGN management. These specifications are not all ITU-T Recommendations, but also come from other standards making bodies with expertise in defining management interfaces. For example, the roadmap tags the 3GPP (3rd Generation Partnership Project) specs for mobile telephony relevant to the IMS (IP Multimedia Subsystem) management. IMS is expected to be a key building block for NGN specifications.

An additional and important feature of the document is that it provides gap analysis, identifying areas where standards are still needed, and also identifies overlapping specifications requiring harmonization.

The aim is for the roadmap to be a living document at this time, which is part of the reason that it hasn’t been turned into an official ITU document – like a Recommendation. Another reason for not giving the document ‘normative’ status is so that non-members can enjoy free access to it.

What: ITU together with sponsors BT, Cisco, Lucent Technologies, Motorola, Nortel and Siemens is holding a one day event to mark a new milestone in ITU's work on next-generation networks (NGN). The event will present an overview of NGN work so far, details on future direction and some of the business drivers for NGN. In addition to announcing this completion of work on the Release 1 standards for NGN by ITU-T's Focus Group on Next-Generation Networks (FGNGN), the event will communicate the next phase of NGN work to be progressed under the banner of the NGN Global Standards Initiative (NGN-GSI).

Morning sessions will focus on technical aspects of the NGN work, while the afternoon will be devoted to market/business drivers. Registration is
required.

When: 18 November, 2005

Where: Hilton, Gatwick, London, UK

Why: Operators from around the globe are implementing NGN strategies and plan to invest billions of dollars in the eventual rollout of new packet-based networks. Their involvement in global standards stimulates innovation and superior technology; enables interoperability allowing multi-vendor product offering; and protects current and future investment.

The operators, systems vendors and governments that have driven this standardization work see NGN as delivering substantial cost savings due to the economies of scope inherent in a single converged network. They believe that standards will facilitate an open market for systems, lowering costs and allowing a mix and match approach to implementation, while also allowing interoperability on a global scale. NGN will see consumers benefit from innovative new services, greater control and personalisation, ease of migration between services as well as offering continuity for existing services.

Work on a standard (ITU-T Recommendation) that updates telecommunication management principles for NGN has been completed in Study Group 4.

Standards here are essential according to SG experts in order to ensure that management solutions support NGN, a network based on the separation of service and transport capabilities.

The work focusing on the interfaces between management systems was mostly led by service providers and is important in order for the dynamic provisioning of services in NGN. The document will also allow for easier planning, installation, maintenance, operation and administration experts say.

The Recommendation - M.3060 - was consented with input from other standards bodies including 3GPP, ATIS, ETSI and the Telemanagement Forum (TMF). It presents the telecommunication management principles, including requirements and four architectural views for managing NGN based on service-oriented architectural concepts.

Study Group 19 was among the three Study Groups meeting in Geneva September. The group that focuses on mobile telecommunications and fixed-mobile convergence reached the first stage of approval (known as consent) on a Recommendation that charts further detail in the migration from GSM (second generation mobile telephony) to UMTS (a member of the 3G family).

Also known as 3GPP Release 6, the Recommendation (Q.1741.4, IMT-2000 family member GSM evolved UMTS Core Networks) combines and associates relevant standards from a number of standards development organizations (SDOs) - ARIB, CCSA, ETSI, ATIS, TTA, TTC - into a globally applicable ITU-T Recommendation.

The SG19 meeting also saw some discussion on the core network architecture of next-generation mobile networks or 4G.

Study Group 4 meets this week in Geneva. The Study Group looks at the interfaces that sit between management systems and network elements, as well as interfaces between management systems.

Dave Sidor, Chairman of SG 4 said prior to the meeting, a key focus will be progressing NGN related specifications and also harmonization of standardization efforts across different standards making bodies. Sidor said that it’s important to identify the overlaps between these bodies in order to avoid duplication of work and ensure that industry’s best needs are served. In this way he said industry ends up with one rather than multiple solutions.

One area that will be discussed in terms of this harmonization is the charging and billing for services in next-generation networks (NGN). Another is in the area of specifications for management of Ethernet based networks.

For possible consent at the meeting is M.3060, a proposed ITU-T Recommendation covering the principles of NGN management.

Also at the meeting the NGN Management Focus Group will report on its activities in particular on the NGN management specification roadmap, a document which identifies the various existing, or work-in-progress specifications for NGN management. These specifications are not necessarily ITU-T Recommendations, but could come from any other standards making body.

September has got off to a flying start as far as next-generation networks (NGN) work in ITU is concerned. The important milestone of the Release 1 set of standards is on track for November and sufficient momentum has been achieved to ensure that the next stages of NGN work will be carried out with similar efficiency.

The continuation of the NGN study by ITU will be re-branded the NGN-Global Standards Initiative (NGN-GSI).

Houlin Zhao, Director of TSB, ITU-T’s secretariat said: “I am very pleased with the progress and the results achieved by the Focus Group on next-generation networks (FGNGN). These first results will provide the building blocks on which the world’s systems vendors and service providers can start to make this monumental shift to NGN. We have the momentum, the tools and the will to continue this significant and important work.”

Agreement on a future plan is clear and the Focus Group on next-generation networks (FGNGN) has been putting the finishing touches to Release 1 before formally submitting it into the Study Group system.

The FGNGN met in Geneva 24 August – 2 September alongside meetings of Study Groups 11, 13 and 19, themselves all having elements of NGN work. Each FGNGN meeting has seen increased participation and contributions according to management.

The group chaired by Chae-Sub Lee of Korea is expecting to see completion of its Release 1 set of standards, at its November 2005 meeting in London, UK. A one day briefing session following that meeting will serve as an overview of the work, as well as an opportunity to promote future direction and business drivers.

The first draft of an allocation table for the distribution of work following the November meeting was also agreed. This type of activity as well as the development of a prototype project management tool, is seen as important in order to keep NGN work, that cuts across the study groups, aligned, coherent and consistent.

According to FGNGN chairman Lee, an important focus of the work at this Geneva meeting are the quality of service (QoS) aspects that will allow – for example – services like IPTV to be offered with the same broadcast quality as traditional TV. The Focus Group expects that there will be more than ten deliverables on QoS that will be submitted into the Study Group system for approval as ITU-T products such as Recommendations. Additionally the topic of fixed-mobile convergence saw much discussion in the meeting according to Lee.

FGNGN also saw the document that describes the scope for NGN standards in ITU reaching near maturity, an important step, according to meeting insiders. The document that gives an overview of what Release 1 is expected to cover in terms of services, capabilities and high level objectives was described in the meeting’s report as ‘very stable’. Additionally much progress was made on another crucial document describing Release 1 requirements.

Recommendation H.460.20 consented at the last Study Group 16 meeting solves the problem of how to provide location information in calls generated to/from H.323 systems. The Recommendation allows these systems – such as VoIP or videoconferencing – to convey information that could be a URL, an e-Mail, a postal code, or a mobile telephone number. This is much more than can be achieved with a traditional public switched telephone network (PSTN) call.

Currently calls generated or terminated in H.323 systems do not carry - end-to-end – details of where that call is coming from. This information is needed by the public switched telephone network (PSTN) for emergency services, more accurate billing and for routing the call. Additionally it is useful, for instance, in applications such as telemarketing where calls can be routed according to their origin. 

Technically H.460.20 gives H.323 the ability to convey the location number present in ISUP – the system that determines the set-up, co-ordination and taking down of calls. Without this ability location information is lost at the interworking edge between the IP network and the PSTN. An additional benefit is that it simplifies interworking with the session initiation protocol (SIP).

ITU-T has agreed to a revision of a Recommendation that experts say is an important step towards solving the problem of lengthy call setups in 3G video telephony. Seen as a key issue to address, the resolution of this issue may help accelerate the market for 3G. 

According to SG 16 sources the standard has been successfully tested in products and many mobile operators and handset manufacturers have started implementation.

The revised ITU-T Recommendation H.324 speeds the initiation of 3G video sessions through the streamlining of the call set-up signalling that is necessary to establish the connection between two handsets and between a handset and a media server.

Previously setting up a typical video session required each end to send up to ten messages to the other terminal, each time waiting for a message to be received and acknowledged before sending the next one. And, if a message was not received, the sending device had to wait and finally time out before retransmitting. The delay introduced in this process led to long video call set-up times.

The new method eliminates the message queuing and time out issues. Now, all signalling is sent as a single batch to be processed by the receiving device. Missed messages, due for example to network errors, are immediately detected by the receiving device and retransmission requests are spontaneously generated. This leads to much quicker call setup times, bringing video connectivity close to the same level of service as traditional telephony.

Key for many operators is that implementation will not require manufacturers to recall phones, also meaning that services may work on existing devices. Other advantages of the new approach include the fact that it is protocol and network independent, enabling connectivity with any other device, even if it is IP-based (e.g. IP video streaming server or a PC-based video terminal) and meaning that it does not interact with underlying network protocols or codecs, enabling devices using the standard to operate even when roaming in other mobile networks.

A suite of ten new standards that provide security for IP media communications such as VoIP or videoconferencing got an update at the last meeting of ITU-T’s Study Group 16

The security framework outlined in the H.235 series of ITU-T Recommendations provides the protocols necessary for these media to be authorised and routed. Equipment using these standards can deliver connectivity without compromising security. 

With the help of the Recommendations, users communicating through IP media are authenticated and authorized so that their communications are protected against various security threats. Real-time multimedia encryption adds a further layer of security, protecting against call interception. The security countermeasures are designed to thwart service fraud, avoid service misuse and detect malicious message tampering. H.235 also gives the ability to provide a greater level of security using public key infrastructure (PKI) certificates. 

Additionally, two new security profiles were added to provide [H.235.8] key exchange using the secure real-time transport protocol (SRTP) in H.323 networks and [H.235.9] to allow discovery of security gateways in the signalling path between communicating H.323 entities, in order to preserve signalling integrity and privacy.

The Focus Group on next-generation networks (FGNGN) has recently completed a technical report that will hand back some elements of network management to the customer.

The document is an approved deliverable of the group that will be submitted to FGNGN’s parent within ITU-T, Study Group 13, for further consideration as a candidate ITU-T product (e.g. Recommendation, supplement, handbook, etc.). It outlines a framework for customer manageable IP networks (CMIP).

CMIP will give end users the ability to manage network elements and resources, such as bandwidth and storage.

Using a menu driven system CMIP will allow end-users to split bandwidth, dedicating, for instance, 1 Mbps to file sharing, .5 Mbps to instant messaging and e-mail, and .5 Mbps to web browsing.

Service providers will benefit by being able to offer this ability as value-add to their Internet service offerings, and will also be able to better provision network resources for services, such as web browsing, VoIP, and peer to peer (P2P), given the increased knowledge of exactly how users are using their bandwidth.

The standardization sector of ITU (ITU-T), together with its development sector (ITU-D) are staging a seminar in Tashkent, Uzbekistan on Standardization of the NGN and ICT Services Development, 5-7 July.

The event follows the invitation of the Communications and Information Agency of Uzbekistan which has also collaborated in the organization of the event.

The objectives of the seminar are to discuss the current trends, status and future evolution of next generation network (NGN) standards, as being addressed by the ITU-T. Central to this discussion will be to ask what areas of technology innovation hold the greatest promise for NGNs and what are the most innovative applications and services possible? Issues revolving around NGN architecture, NGN technology and quality of service requirements and evolutions will also be explored.

A call for presentations has been issued for the upcoming workshop, Mobile Communications & Fixed/Mobile Convergence - the realities going forward. The event is to be held in Kiev, Ukraine, 12 - 14 September 2005 and will look at the current status of fixed-mobile convergence and examine what the future holds.

There are now more mobile users than fixed users globally. In many countries, the ratio of mobile to fixed users is heavily in favour of mobile. This demographic shift requires an essential re-examination of the relationship between fixed and mobile networks. ‘Mobility’ plays a key role in the development of next generation networks (NGN).

It is anticipated that case studies illustrating examples of convergence from around the world will help to identify the needs and action plans for the region that this event is being held in.

Presentations should highlight ongoing work in ITU and elsewhere on mobile telecommunications networks, in particular the work on IMT-2000, fixed mobile convergence and guidelines on the transition of existing mobile networks to IMT-2000 / NGN.

The deadline to submit abstracts (maximum 400 words) and biographies (maximum 200 words) is 31 July 2005. Submissions may be sent via e-mail to: tsbworkshops@itu.int.

The deployment of NGNs will create a great opportunity for new services offering, more integrated features, and a more extensible and flexible platform for future applications. NGN is a key area of study for ITU-T study groups. Based upon the Internet Protocol (IP), the convergence between public switched telephone network (PSTN), digital subscriber line (DSL), cable television (CATV), wireless local area network (WLAN) and mobile technologies is a task that many believe would be impossible without the development of global NGN standards.

The NGN concept takes account of a new situation in telecommunications, characterized by many factors: open competition between operators due to the deregulation of markets, explosion of digital traffic, e.g. due to the increasing use of the Internet, the demand from users for new multimedia services requiring higher bandwidth and the new user necessity for a generalized mobility.

ITU-T involvement in NGN started in early 2002. Since that time many workshops have been organized in order to widen the scope of ITU’s work on IP-based networks and later on NGN and explore specific issues that impact both ITU and other standards developing organizations (SDOs). A Joint Rapporteur Group (JRG-NGN) initiated standardization work on NGN in September 2003 and the effort was later strengthened by the establishment of the focus group on NGN, in June 2004. Currently many ITU-T study groups are involved in NGN standardization work and SG13 is the Lead SG for NGN.

In a first for ITU-T, reports from a recent meeting of the Study Group which looks at mobile telecommunication networks (Study Group 19) have been made publicly available on the web. Other SG 19 documents  have also been made available in the experiment and are identified by the words ‘public access’ in red type on the web site.

The trial which will last until the end of 2006, is a result of discussion at the World Telecommunication Standardization Assembly (WTSA) and meetings of the Telecommunication Standardization Advisory Group (TSAG).  

The available reports cover the May 2005 meeting in Geneva and provide both an in-depth look at the week’s proceedings, and give insight into the workings of a typical ITU-T study group.

The meeting report highlights SG 19’s role in the work on NGN, and in particular outlines its work in the area of fixed-mobile convergence.

The aim of the trial is to give interested parties, such as students, analysts and journalists, as well as others interested in contributing to the work of ITU-T, and SG 19 in particular, access to documents that will enable them to better understand both the nature of the technical work and the standardization process.

It will still be necessary, because of commercial, legal and other sensitivities, that some documents are restricted to ITU-T-members-only access.

The Open Communications Architecture Forum (OCAF), a Focus Group operating under the auspices of the ITU-T,
has produced its first official publication. OCAF was created in May 2004 to accelerate the adoption of an ecosystem of open standards components in next generation networks (NGN). The mission of OCAF is to help service providers, equipment and software vendors address the complexity of moving to these new packet-based systems. Selected outputs of OCAF will be submitted for approval as ITU-T Recommendations.

The Carrier Grade Open Environment (CGOE) Reference Document – outlines a framework for the open interfaces and standards required to deploy solutions based on standardized commercial off-the-shelf (COTS) components in NGNs. Available from the OCAF webpage, the CGOE Reference Document is intended for an audience that aims to integrate solutions containing components from multiple, different, COTS software and hardware vendors.
Typically this will include service providers, solution providers and technology providers.

The model is consistent with the concept that technology providers deliver components to solution providers who then subsequently provide solutions to service providers. OCAF members are already using the model to deploy NGN services and promote best-of-breed component reuse and interoperability in a multi vendor environment.

OCAF has also published a white paper, outlining its work. The white paper, also available from OCAF's webpage details the group's raison d'être as well as giving a detailed mission statement.

ITU-T has completed the specifications necessary for telecoms operators around the world to offer a ‘super’ triple play of video, Internet and voice services.

The ITU-T Recommendation for very-high-bit-rate digital subscriber line 2 (VDSL2) will allow operators worldwide to compete with cable and satellite operators by offering services such as high definition TV (HDTV), video-on-demand, videoconferencing, high speed Internet access and advanced voice services including VoIP, over a standard copper telephone cable.

VDSL2 will offer consumers up to 100 Mbps up and downstream, a massive ten-fold increase over the more common ADSL. Essentially it allows so-called ‘fibre-extension’ bringing fibre like bandwidth to premises not directly connected to the fibre-optic segment of a telecoms company’s network.

As well as addressing increasing consumer demands, VDSL2 offers telecom carriers a solution that promises to be interoperable with the ADSL kit that many operators already have in place. This interoperability will make the migration of customers to VDSL2 much simpler. Another important feature of VDSL2 is that it will work in both legacy ATM networks and next generation IP based networks.

VDSL2 is seen by many operators as an ideal accompaniment to a fibre to the premises (FTTP) rollout, where for instance fibre is supplied direct to an apartment block and from there copper cable is used to supply residents with high-speed VDSL2.

Yoichi Maeda, chairman of the Study Group responsible for the work said: “We have leveraged the strengths of ADSL, ADSL2+, and VDSL to achieve the very high performance levels that you will see with VDSL2. It looks set to become an extremely important feature of the telecommunications landscape and is a landmark achievement for our members, many of whom were relying on this Recommendation in order to take their businesses to the next level.”

The publication of standardized specifications in an ITU-T Recommendation (G.993.2) means that operators can avoid being locked into a single vendor. As well as the economic advantages that this may bring it also means that operators can select the best solutions according to their needs.

In between the meetings of two lead technical groups working on image and video compression, ISO/IEC's JPEG and ITU-T's Study Group 16, ITU will host a workshop on Video and Image Coding and Applications (VICA) at ITU headquarters, Geneva, 22 to 23 July. 
Key experts will join users to review the development, assessment and application of video and image coding and to discuss and start work on an action plan and a roadmap for VICA standardization.

Presentations will instigate discussion on how standards work in the field, including how next generation networks (NGN) can support the development of so-called ubiquitous services - any device, anytime, anywhere. Current work on home network environments will also be taken into account.

Also at the event there will be an interoperability demonstration showing various products using related standards.

All interested parties are free to attend.

ITU-T will lend its support for a second time to an event on the topic of wideband speech quality in terminals and networks held by ETSI. The last event concluded that there is a lack of speech quality specifications and adequate tools for assessment and planning of wideband speech communication systems. This is a critical issue as wideband systems are to be one of the driving factors in next generation networks (NGN).

To be held 22-23 June, Mainz, Germany, this workshop will provide an overview of developments since last year's event, including the voice quality prediction tool or e-model designed by ITU-T experts (see previous e-Flash story). Additionally the event will examine in technical detail the general aspects of terminal testing and reference points for wideband terminals, and there will be discussion on the requirements for wideband applications that are specific to wireless and VoIP scenarios.

The joint ITU-T/Internet Engineering Task Force (IETF) workshop on next generation networks (NGN), 1 - 2 May, 2005, Geneva, reported in last month's e-Flash has attracted sponsorship from global networking company, Cisco Systems. 

Cisco has agreed - using ITU's voluntary contribution mechanism for donating funds beyond membership fees - to contribute to NGN activities in general, including this and a future workshop.

Jeff Spagnola, VP Worldwide Service Provider Marketing will deliver an address to the workshop outlining the Cisco vision for NGN. Ahead of the event he said: "Cisco is pleased to provide support for this important event, as well as ongoing NGN activity simply because we believe strongly in the value of standardization for NGN and the emerging definitions that will put us on the road to a truly converged ICT world. Cisco has been very active so far in NGN technology, and Cisco will continue to play a key role in this work as we move forward."

ITU-T will hold a workshop on NGN together with the Internet Engineering Task Force (IETF), 1 - 2 May, 2005, Geneva. The workshop will also serve as an important meeting point for ITU-T and IETF management.

The overall objectives of the workshop are to explore specific NGN issues that impact both the ITU-T and the IETF to better understand the work underway in the two organizations and to identify areas where actions could be taken between the ITU-T and IETF to further coordinate their work.

Six sessions will each be co-chaired by an ITU representative and a representative from IETF. Topics will include requirements and functional architecture; nomadicity and mobility; QoS, control and signalling capabilities; network management; security capabilities and evolution.

The workshop, the second on NGN in 2005, is an example of the way in which ITU-T is seeking to engage all interested parties in work towards the development of worldwide standards for NGN. In this way, industry demands for the efficient and swift completion of the specifications that will define the way that NGNs work will be met.

A recent meeting of Study Group 12 saw progress in the development of QoS-related standards for IP-based networks and services.

QoS is seen as a key area to address in IP-based networks, especially as more carriers announce plans to carry voice traffic using the protocol.

Progress was made on the revision of Recommendation G.1020 which gives performance parameter definitions for quality of speech and other voiceband applications utilising IP networks. The updates will specify voice quality measurements associated with the use of the VoIP management protocol, RTP Control Protocol Extended Reports (RTCP XR). RTCP XR defines a set of metrics that contain information for assessing VoIP call quality and diagnosing problems.

And Y.1541 which gives network performance objectives for IP-based services, is also actively under revision to include new QoS classes with more stringent packet loss performance, needed for example for commercial video applications and certain TCP formats.

Also during its meeting - the first of the new study period - SG12 consented a revision of Recommendation G.107 (the E-model, see previous e-Flash story, to include an improved treatment of bursty packet loss.

ITU-T is to hold an NGN Technical Workshop, 14 - 15 March 2005 at the Lotte Hotel, Jeju Island, Korea, at the kind invitation of the Korean Government. The workshop will serve as a useful review point on the road towards NGN, and precedes a meeting of the Focus Group on NGN (FGNGN).

In May of 2004 study on NGN standards found a home at ITU, with the formation of the FGNGN. Since that time intense work has taken place in this group and across many of ITU-T’s other study groups, towards the development of standards that will define services, network and systems architecture in IP enabled next generation communication systems. Indeed NGN has become a key area of study for ITU-T’s study groups. Study groups 2, 11, 13 and 19 for example have a significant NGN focus (Study Group 13 is the lead Study Group for NGN).

The convergence between internet protocol (IP), public switched telephone network (PSTN), digital subscriber line (DSL), cable television (CATV), wireless local area network (WLAN) and mobile technologies is a task that many believe is impossible without the development of global standards. NGN will offer a richer set of applications to the end user. The work of FGNGN and other ITU-T groups will build on existing fixed/mobile convergence architecture (e.g. 3GPP/3GPP2 IP multimedia subsystem (IMS)) to provide transparency between fixed and mobile networks.

Among many recent achievements in the NGN field are an output relating to IP-QoS signalling for inclusion in the first set of specifications (Release 1), the foundation of a 'joint coordination activity' (NGN-JCA) aiming to see that standards are developed in the most appropriate place and that no duplication of effort occurs and the development of a project management tool that will give a unique overview of the NGN work going on across the standardization world.

A new ITU-T Recommendation from Study Group 16 aims to support the continued use of modems in IP networks by providing interoperability between products that emulate modem signals. A number of products had emerged to provide this functionality, but no standard solution - until now.

Modem signals have traditionally been transported by circuit switched systems and equipment. As service providers increasingly look towards Internet Protocol (IP) infrastructure, more modem signals will be carried over the protocol. The problem is that the basic design constraints of IP networks do not allow for transparent transport of modem signals (voice-band data (VBD)), hence necessitating special protocols to be run on top of IP to ensure the necessary end-to-end high quality of service.

Many thousands of people still use dial-up (modems) to access the Internet, and so the continued support of modems as many telecommunication service providers move to packet based networks is seen as imperative. Without standards that support their continued use, modem users would suffer from a significantly downgraded experience.

V.152 defines procedures for equipment that interconnect traditional circuit-switched networks with IP networks to provide satisfactory, transparent delivery of modulated VBD as encoded audio content over IP (data modems, facsimile terminals and text telephones). The Recommendation complements the functionality in the modem relay Recommendation V.150.1 (see press release).

In its first meeting of the new study period, Study Group 13 started work on a set of activities to speed up the development of, and provide clear direction for NGN standardization work. ITU-T will implement in the first half of 2005 a set of tools that will give a unique overview of the next generation network (NGN) work going on across the standardization world.

Since the work towards standards for NGN is taking place across a number of different ITU-T study groups and other standards development organizations (SDOs) the ability to coordinate and view all NGN work in one place will be invaluable to the swift and efficient publication of the first set of NGN specifications (Release 1).

The tools – essentially a repository of information from ITU and other SDOs – were asked for by members of the NGN Focus Group. Key will be the ability to keep track of the latest versions of documents and provide detailed information for experts and summaries for management.

ITU-T's Study Group 19 has developed and approved a technical report that will facilitate interoperable and harmonized wireless network architectures. This is a key aspect of the overall ITU-T focus on next generation networks (NGN).

The convergence of fixed and wireless networks has become a key topic for forward-looking standardization, especially in NGN. This, together with the convergence of telecommunication and information technologies, and the drive for migration to interoperable and harmonized network architectures, means that there is a requirement to provide global roaming and seamless mobility for the users of the different access technologies used by different operators.

To this end, ITU-T's Study Group 19 is leading the definition of requirements, related architecture framework, and network to network interfaces (NNIs) for mobility management for the next generation mobile networks defined in ITU-T's systems beyond IMT-2000. The technical report by Study Group 19 identifies the requirements that will enable the development of protocols which are essential for the development of next generation mobile networks. It is recommended reading for anyone working in this area as it provides an excellent summary of the requirements and options for meeting them.

A recent meeting of Study Group 13, the lead study group on NGN, saw the establishment of a group that will ensure that work across ITU-T’s study groups is focused on delivering NGN standards in a timely and efficient way. Essentially the group will aim to see that standards are developed in the most appropriate place and that no duplication of effort occurs.

The ‘joint coordination activity’ (NGN-JCA) group initially consists of management representatives of study groups 2, 11, 13 and 19.

The meeting also saw agreement on a draft action plan to support the involvement of developing countries and countries with economies in transition in its work. This follows a mandate given by the world telecommunication standardization assembly (WTSA) to ensure that ITU-T's standardization work continues to address the digital divide between rich and poor countries. In line with Study Groups 15 and 16's recent announcements the move will ensure that developing countries' needs are taken into account in the development of standards.

New specifications ratified by ITU-T Study Group 11 will transfer some of the call control elements of SS7 to the IP world. SS7 is the signalling system used by telecoms operators worldwide to allow the efficient routing of calls, and its worldwide implementation has paved the way for an efficiently operating international telecommunication network.

The new Recommendation - Q.1980.1- defines narrowband signalling syntax (NSS), a flexible text-based syntax that can be used to transfer narrowband signalling information in protocols that cannot inherently transfer such information (eg the session initiation protocol (SIP)).

This NSS solution aims at helping operators reflect the services that they provide in the public switched telephone network (PSTN) in next generation IP based networks. It provides a standardized set of PSTN/ISDN services signalling parameters that can be mapped into the many SS7 ISDN user part (ISUP*) variations, to be transmitted transparently through IP networks. NSS has been designed to enable seamless interworking between the PSTN and IP networks and transition from legacy TDM (time division multiplexing) circuit switched networks to packet-based transport technologies without service degradation or changes.

* ISUP determines the procedures for setting-up, coordinating and taking down calls on an SS7 network. It provides calling party number information, call status checking, and controls tone and announcement delivery.

The NGN Focus Group has delivered its first output for inclusion in the first set of specifications for next generation networks (NGN) - Release 1. The document (a supplement to ITU-T's Q series recommendations, approved at the last Study Group 11 meeting) relates to IP-QoS signalling.

QoS signalling provides a way for network elements to communicate with, or signal, other elements to request special handling of certain traffic. QoS signalling is useful for coordinating the traffic handling techniques provided by other QoS features. It plays a key role in configuring successful end-to-end QoS service across a network.

In this case the document - a technical report - identifies the requirements for signalling information regarding IP-based QoS at the interface between the user and the network (UNI) and across interfaces between different networks (NNI) including access networks.

Identifying these requirements and the signalling information elements will enable the development of signalling protocols which are essential for the development of services based on IP-QoS in NGN.

A new standard approved by ITU provides interworking between two dominant technologies in next generation networks (NGN). Ethernet and MPLS (multiprotocol label switching) are critical components of the evolving broadband architecture.

The standard - ITU-T Recommendation - Y.1415 - is likely to help further Ethernet’s push towards becoming a carrier class service delivery technology, and aid MPLS’ move towards playing a bigger role in NGN.

The ability to offer Ethernet services means that carriers will be able to offer considerably improved flexibility to customers through a much simpler and lower cost interface. It will allow users to specify exactly how much bandwidth they want between the 10Mbit/s and 1Gbit/s range currently offered. MPLS will add the quality of service (QoS) requirements that service providers demand to the Ethernet package. Further, the standards provide reduced operation complexity and improved scalability for carriers.
