ITU-T Workshop on "Telecommunication Management and Operations Support System"
Beijing, China, 22-23 May 2006

An ITU-T workshop on Telecommunication Management and Operations Support System will take place at the XinYuan Hotel in Beijing, China, from 22 to 23 May 2006 inclusive, at the kind invitation of Beijing University of Posts and Telecommunications (BUPT). The workshop will be held prior to ITU-T Study Group 4 meeting which will be held at the same venue from 24 May to 2 June 2006 inclusive.

As the lead Study Group on telecommunication management, ITU-T Study Group 4 is responsible for studies regarding the management of telecommunication services, networks, and equipment, including support for next generation networks (NGN) and the application and evolution of the telecommunication management network (TMN) framework. Additionally, it is responsible for other telecommunication management studies relating to designations, transport-related operations procedures, and test and measurement techniques and instrumentation.

Joint ITU-T Workshop and IMTC Forum 2006 on "H.323, SIP: is H.325 next?"
San Diego, California, USA, 9-11 May 2006

The rollout of NGN will bring with it in a new era of multimedia communications and with that a need to consider updating or replace the currently used H.323 and SIP multimedia protocols.

The question is whether to pursue development of a new protocol and a new generation of multimedia communication systems, or define new multimedia capabilities and functionality for existing protocols. Perhaps some consideration needs to be given to service control interface specifications. With work already underway in ITU on a new protocol dubbed H.325, the industry must decide whether to invest more time and resource into this pursuit.

A revision to a commonly used ITU-T Recommendation will extend use of fibre previously used mainly in core networks to metropolitan or regional networks. Crucially it also has the potential to greatly reduce operating costs for network providers.

G.655 for non-zero dispersion-shifted fibre (NZDSF) was originally designed to support DWDM long distance core, it was designed to reduce a phenomenon called four wave mixing (an interaction between wavelengths that generates additional optical channels). The impressive improvement in dispersion profiles afforded by G.655 fibre together with the development of the G.692 standard for optical interfaces for multichannel systems with optical amplifiers led to an explosion in the market for DWDM systems experts say.

Reduced dispersion allows sending signals over greater distances without dispersion compensation, meaning that operators will be able to avoid using a compensator and amplifier as well as the costs associated with this; power, protection, housing and security.

The revision to G.655 (full title, Characteristics of a non-zero dispersion-shifted single-mode optical fibre and cable) deals with chromatic dispersion, a phenomenon which at low levels counteracts distortion, but at high-levels can make a signal unusable. The management of chromatic dispersion is crucial as the number of wavelengths used in WDM systems increases. ITU has a history of providing the specifications that allow operators to most efficiently handle this. The revision allows more efficient use of the properties of chromatic dispersion by more stringently defining its existence. It defines chromatic dispersion in two new categories that can be exploited by systems designers as necessary.

The need for the work stemmed from systems' designers want to better understand dispersion. And a result is that experts saw a use for G.655 cable in metro or regional networks where it had previously only been used in core networks.

"ITU can play an important role in furthering international standardization efforts (for networked RFID) in addition to raising awareness about the challenges and opportunities of this exciting new technology." That was a conclusion of attendees representing standards bodies, telecoms service providers, vendors and academia at a recent workshop Networked RFID: Systems and Services.

Participants agreed that standardization in the field is essential in order to roll out the technology on a global scale. Experts agree that standards so far have developed in a fragmented way; one example is the to-date weak coordination between different regional bodies. Event steering committee chairman, Pierre-Andre Probst, said that many new work areas have been identified for ITU as a result of the workshop, giving further momentum to work already started in some ITU-T Study Groups. Contributions on RFID are expected in the Study Group meetings taking place in April (Korea, Switzerland and Japan) and based on the outcome of discussions here an action plan will be developed in May.

Radio frequency identification (RFID) is a key part of the so-called Internet of Things, or as one session chair put it: "RFID is part of a larger vision of future technological ubiquity".

Object-to-object communication has the potential to revolutionise commerce, with many areas of business already benefiting from the use of RFID. But there are wide ranging applications for this new technology beyond just making money. For example in Japan there have been trials to use RFID to track children on the way to school, making sure they get safely to their destination. In European ski resorts, RFID ensures that skiers don't have to fish around in their pockets with cold hands for their ski passes now that RFID equipped passes have become widely adopted. A more serious upshot of this application is that now resort managers know how many people are on the slopes at any given time, crucial information in an emergency.

As the technology takes off, increasingly complicated applications are envisaged. RFID systems are moving from closed reader and tag systems to systems where there is a need for a network to share data. While now incipient, presenters at the workshop forecast that the message traffic will increase exponentially over the next 10 years, which will have an impact on existing and future communication infrastructure. And this is where the need for standards becomes more of an imperative.

The 'Internet of things' it was said will lead to a new set of network requirements and capabilities as potentially billions of tags start to transmit data. Network requirements and capabilities for more-complicated services that include sensors must also be taken into account. Sensors can monitor environmental variables. Their combination with RFIDs will not only identify people or objects, but also provide in addition to location other dynamic attributes such as temperature, movement and acceleration.

Specifically ITU expects to examine network and service architecture, requirements for machine-to-machine communication, security, information service protocols, interoperability, data format, radio frequency spectrum allocation, network performance and quality of service in its technical study groups.

As far as security is concerned, consumer protection, namely privacy and data protection, has hindered user acceptance and so addressing this area is seen as a prerequisite for public acceptance. ITU has much experience in this field, particularly in the important area of alignment with policy and regulatory issues.

Global frequency harmonization is a hindrance according to some experts towards achieving supply chain efficiencies and security. This is a topic expected to be raised at the upcoming World Radiocommunication Conference (WRC), Geneva, 2007, and workshop participants suggested the need to establish RFID as a Primary Service.

ITU is also expected to help coordinate ongoing standards work in the field in order to avoid work duplication. Among the groups operating in the area are ISO, ETSI, IEEE, EPCglobal and Near Field Communication Forum.

A new Recommendation identifies the needs required to give end-to-end visibility of client services carried across multi-carrier networks. Without this ability carriers have often had to wait for customers to report problems before they can begin to address them.

The Recommendation - G.8601 - identifies the requirements for the next stage of work which will focus on methodologies to address this issue. Study group experts report that contributions to this end have already
been received.

G.8601 defines architectural requirements for the edge-to-edge management of client services transported over various transport network topologies and technologies. The services for which such management capabilities are required are also included.

The requirements for the transference of the management data between the edge points are described along with the requirements for accessibility to management information at some point in the network, other than the end point.
