Question 25/13 – Coordination, Planning, and Terminology
(Merger of Qs 1/13 and 2/13)

A major goal associated with the evolution of networks is to facilitate the convergence of networks and services. This is a complex process and as a result there is a 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.

Requests to work on new areas such as IPTV, smart networks, ubiquitous, networks, future networks, etc. have emerged. It is recognized that there is a great need for coordination and planning function to support the ongoing evolution of networks.

Furthermore, as IP based networks and IP-based applications gain importance in the industry, there is a growth of new terminology used in the developing standards. ITU-T will define its own terminology and elaborate on the definitions of current terminology. In order to establish common language for the industry, in which the ITU plays a key role, it is essential to ensure to the extent possible that each concept, architectural element, protocol action, pieces of equipment, etc. is assigned a unique term. For the cases where several such terms have already been defined, it is important to indicate all synonyms pertinent to a particular notion.

This Question is intended to address the needs associated with the ongoing support of this coordination and planning function, and for consolidation and elaboration of terminology.

Regarding Coordination and Planning, Recommendations under responsibility of this Question include: Y.2006, Description of capability set 1 of NGN release 1; Y.2007, NGN capability set 2; 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; Supplement 7 to Y-series – ITU-T Y.2000 series: Supplement on NGN release 2 scope

Regarding terminology, Recommendations under responsibility of this Question include: Y.101, Y.2091, Y.1991

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.
    Definitions of concepts, architectural elements, protocol actions, pieces of equipment, etc. that have been identified in the IETF standards-track requests for comments (RFCs), ITU-T Recommendations, ISO standards, and normative output of other organizations recognized by ITU-T.
  • Terms identifying such concepts, architectural elements, protocol actions, pieces of equipment, etc. It is essential to establish consensus on as few terms as possible (preferably, only one term) for a unique notion.
  • Updating of existing terminology Recommendations (i.e. Recommendations Y.101, Y.1991and Y.2091).
  • Produce new terminology Recommendations or other documents as required.
  • 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 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, smart, ubiquitous, and future networks to achieve the planned results in an official and timely manner.
  • Regular updating of the NGN, smart, ubiquitous, and future networks road maps and project management database
  • Publishing reports on progress
  • Support workshops and other activities as appropriate to increase awareness of the ITU-T work on NGN, smart, ubiquitous, and future networks.
  • The consolidated definition and terminology should be published in new and revised ITU-T Recommendations, which should be re-issued on an on-going basis as the terminology develops.
Recommendations: Y-series and all future network related Recommendations

Questions: All NGN, smart, ubiquitous, and future network related Questions

Study groups: ITU-T, ITU-R and ITU-D study groups involved in the NGN, smart, ubiquitous, and future networks standardization work

Standardization bodies, fora and consortia: Liaison with SDOs and other bodies involved in NGN, smart, ubiquitous, and future networks standardization and implementation as appropriate
