Study Group 2 has recommended the allocation of the international dialing code 888 to the UN for use in disaster relief situations.

It means that in cases where the telecoms infrastructure is down, UN teams can quickly get a communications system up and running for use in coordination. The recommendation was made following a request from the United Nations Office for the Coordination of Humanitarian Affairs (OCHA). The Director of ITU's Telecommunication Standardization Bureau (TSB) will study the recommendation from Study Group 2 to allocate the code.

Study Group 2’s February meeting saw work continue on harmonizing numbering resources for child helplines.

SG 2 is looking at the issue following a request from Child Helpline International (CHI). CHI is a global network of telephone helplines and outreach services for children and young people.

Specifically SG 2 is looking at the logistics of providing a global number. It previously conducted a survey which discovered that a wide range of numbers are in use globally and that there is support in many countries for studying a more harmonized solution.

A review process will be an initial assessment of all of the various options for introducing childrens’ helplines. The fundamental question is whether a single number can be deployed worldwide. Other issues include how regulators will handle migration from existing services and who pays for the services.

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.

A new Recommendation from SG12 acts as a performance planning tool for videophone applications taking into account the effects of video as well as voice quality. The computational model described is for point-to-point interactive videophone applications including dedicated videophone terminals, desktop or laptop PCs, PDAs and mobile phones over IP networks.

Recommendation G.1070 gives an algorithm that estimates videophone quality in terms of quality of experience/quality of service (QoE/QoS). The model is designed to be used by QoE/QoS planners to help ensure end-to-end user satisfaction and to avoid over-engineering at the application, terminal, and network layers.

Study Group 12 consented a new Recommendation that provides a way to give consistency to performance measurements in high layer protocols such as FTP, HTTP etc.

The Recommendation, ITU-T Recommendation Y.1562, may be used by service providers in the planning, development, and assessment of IP service to check that it meets user performance needs; by equipment manufacturers to give performance information that will affect equipment design; and by end users in evaluating higher layer protocol service performance.

A Recommendation that ensures that sound levels between various devices are harmonized in order that listening quality is not degraded was amended at Study Group 12’s January meeting.

The amendment takes into account the transmission characteristics for headsets and hands free terminals. The original Recommendation – P.313 - provides audio performance requirements for portable digital cordless and mobile handsets, headset and loudspeaker terminals.

Specifications for car mounted hands free terminals will be treated in a new Recommendation in progress and also under study in the Focus Group - From/In/To Cars Communication.

A revised workplan for some of the Questions in Study Group 12 will include specific mention of IPTV Quality of Experience (QoE) and Quality of Service (QoS).

The latest meeting of Study Group 12, Geneva, January, also saw agreement on a definition for QoE. This, experts said, is particularly important given the inclusion of QoE in the definition of IPTV agreed by the ITU-T IPTV Focus Group. (See previous story).

Quality of Experience (QoE)

The overall acceptability of an application or service, as perceived subjectively by the end-user.

NOTES

1     Quality of Experience includes the complete end-to-end system effects (client, terminal, network, services infrastructure, etc).

2     Overall acceptability may be influenced by user expectations and context.


Study Group 12 Vice Chair, Chuck Dvorak, said that he expects that IPTV and other multimedia QoS and QoE issues will see increasing attention in SG12 moving forward.

Dvorak also said that he expects that the non-transport aspects of networks and services, for example call processing performance, will also receive more attention. Additionally he says that he expects SG12 will take a closer look at how to better address the needs of developing countries in terms of QoS.

Representatives of the car industry joined with more traditional ITU-T members at the first meeting of the Focus Group From/In/To Car Communication.

The Focus Group meeting in Geneva, January, worked on specifications that will enhance communications in vehicles. Using as a starting point a specification developed by the German Association of the Automotive Industry (VDA) the Focus Group is looking to improve a draft Recommendation – P.Carhft – under development by ITU-T’s Study Group 12. The Focus Group concept allows for non-members, in this case the auto industry to participate.

A first priority is to deal with speakerphone audio quality, aiming to provide a specification that will help to improve the speech- and sound - quality between different devices. Second priority is requirements for headsets including wireless. Chairman of the group, Hans Gierlich of Head Acoustics noted also that a major problem for the car industry is car-to-car communications.

While first concentrating on narrowband speech (3.4kHz), the group will eventually move into better quality - wideband (8kHz). Input is also required in the area of testing for interaction between the network and hands-free terminals. In addition speech recognition will be addressed.

Participating companies included Alcatel-Lucent, Avaya, DaimlerChrysler, France Telecom, Harman/Becker, Head Acoustics, Mitsubushi, Nortel and Volkswagen.

A second FG meeting hosted by HARMAN/BECKER Automotive Systems is planned for March 15 in Ulm, Germany following the ITU, ISO and IEC event, The Fully Networked Car, Information and Communication Technologies in Motor Vehicles. The event taking place at the Geneva Motor Show will review and examine the implications of the latest developments in this fast-moving market. A significant value-add will be an exhibition showcasing the latest technologies in the field.
