(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
- 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,
- 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
- 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.

implementation as appropriate
