Motivation

A major goal associated with the evolution of implemented networks is to facilitate the convergence of networks and services. This is a complex process and as a result there is a continued need to coordinate ITU-T activities related to the evolution of existing networks, in particular the development of implementation guidelines and standards to facilitate the evolution of current networks.

In the 2005-2008 study period, an NGN coordination and release planning function was established and a number of Recommendations supporting this process were developed with many more under way, including development of basic communication capability sets, called capability set 1 of NGN release 1, based on the concept of release planning.

Requests to work on new areas such as IPTV, and future networks, other than NGN, have emerged, and additional such requests may be anticipated even if their particular content is currently unknown. While it has become clear that it is too complex to continue the concept of release planning in an environment where networks are evolving to next generation networks, ubiquitous networks, etc. it is recognized that there is an even greater need for a coordination and planning function to support the ongoing evolution of networks.

This Question is intended to address the needs associated with the ongoing support of this coordination and planning function.
Recommendations under responsibility of this Question include: Y.2006, Description of capability set 1 of NGN release 1; Supplement 1 to Y-series – ITU-T Y.2000 series: Supplement on NGN release 1 scope; Supplement 5 to Y-series – Y.1900 series: Supplement on IPTV service use cases; draft Supplement to Y-series – ITU-T Y.2000 series: Supplement on NGN release 2 scope

Question

Study items to be considered include, but are not limited to:

• Ensuring that all elements required for interoperability and network capabilities to support applications globally across the networks are addressed by ITU-T standardization activities
• Coordination of the future development of the networks in cooperation with the ITU-T study groups and with other standards development organizations (SDOs) e.g. the IETF
• Coordination required for interoperability of satellite with NGN and/or future networks and to enable a continuing and full integration of the satellite transmission medium in public networks, taking account of emerging technologies and services
• Collaboration as appropriate with other SDOs to avoid duplication of standardization work and identification of additional work necessary.
  What enhancements to existing Recommendations are required to provide energy savings directly or indirectly in information and communication technologies (ICTs) or in other industries? What enhancements to developing or new Recommendations are required to provide such energy savings?

Tasks

Tasks include but are not limited to:

• Developing plans which allow for coordination of evolutions of networks in an orderly fashion.
• Ensure communication and cooperation amongst study groups and fora related to NGN and future networks to achieve the planned results in an official and timely manner.
• Regular updating of the NGN and future networks project management database
• Publishing reports on progress
• Support workshops and other activities as appropriate to increase awareness of the ITU-T work on NGN and future networks.
