• NGN has become a major aspect of the work of
the ITU-T, reinforced by the positive outcomes of
a number of ITU-T workshops and by the
growing interest and involvement in NGN work
in the Study Groups
• Study Group 13 responded by the setting up of
an NGN-2004 Project and by initiating intensive
work on the definition of NGN and preparation of
a set of ‘foundational’ Recommendations on
NGN

The ITU-T NGN Project
The aim of the NGN Project is to identify and
coordinate all ITU-T activities related to the
establishment of implementation guidelines
and standards for the realisation of a Next
Generation Network. A major task of the
Project is to ensure that all elements required
for interoperability and network capabilities
to support applications globally across the
NGN are addressed by ITU-T standardisation
activities.

ITU-T Definition of a Next Generation
Network
A Next Generation Network is a packetbased network able to provide services
including Telecommunication Services and
able to make use of multiple broadband,
QoS-enabled transport technologies and
in which service-related functions are
independent from underlying transportrelated technologies.
GSC-9, Seoul
It offers unrestricted access by users to
different service providers.
It supports generalised mobility which
will allow consistent and ubiquitous
provision of services to users.
GSC-9, Seoul
An NGN is characterised by the
following fundamental aspects
• Packet-based transfer
• Separation of control functions among
bearer capabilities, call/session, and
application/ service
• Decoupling of service provision from
network, and provision of open
interfaces
GSC-9, Seoul
• Support for a wide range of services,
applications and mechanisms based
on service building blocks (including
real time/ streaming/ non-real time
services and multi-media)
• Broadband capabilities with end-toend QoS and transparency
• Interworking with legacy networks
via open interfaces
GSC-9, Seoul
• Generalised mobility
• Unrestricted access by users to
different service providers
• A variety of identification schemes
which can be resolved to IP addresses
for the purposes of routing in IP
networks
• Unified service characteristics for the
same service as perceived by the user
GSC-9, Seoul
• Converged services between Fixed/Mobile
• Independence of service-related
functions from underlying transport
technologies
• Compliant with all regulatory
requirements, for example concerning
emergency communications and
security/privacy
GSC-9, Seoul
NGN project status
• Study Group 13 has set up a task force
to speed up the initial phase of the
work: JRG-NGN (next meeting in June)
• Currently working on a set of
foundational Recommendations
(planned for approval in 2004)
• Growing involvement of other Study
Groups
GSC-9, Seoul
Draft Study Group 13 NGN
Recommendations
• Y.NGN–Overview: General overview of NGN
functions and characteristics
• Y.GRM-NGN: General reference model for NGN
• Y.NGN-FRM: Functional architecture model
• Y.NGN-SRQ: NGN service requirements
• Y.NGN-MOB: Mobility management
requirements and architecture for NGN
GSC-9, Seoul
• Y.NGN-MAN: Framework for manageable IP
network
• Y.NGN-MIG: Migration of networks (including
TDM networks) to NGN
• Y.NGN-CON: Regulatory consideration of the
NGN
• Y.e2eqos: End-to-end QoS architecture for IP
networks evolving into NGN
• Y.123.qos: A QoS architecture for Ethernetbased IP access network
GSC-9, Seoul
Future activities
• Further work on the NGN foundational
Recommendations in Study Group 13 and
on specific NGN Recommendation in the
other Study Groups
• Further development of the NGN Project to
include all required new standards and
release plans and to take account of any
restructuring of the ITU-T Study Groups
GSC-9, Seoul
• Study Groups will include NGN issues in
their new questions for the new study
period
• Collaboration with other SDOs and
regional standards organisations to
ensure harmonisation and globalisation
of NGN through the focus of the ITU-T
GSC-9, Seoul
• Consideration of additional ways to
concentrate NGN standardisation efforts
and to respond to the needs of industry
e.g.
– setting up of one or more ‘Focus Groups’ on
NGN
– increased project working in the ITU-T
GSC-9, Seoul
Discussions with the OCAF
• Initial contact with Open Communications Architecture Forum
ad hoc group (11 March) - ITU-T offers to host the Forum as a
Focus Group
• Discussions with Study Group 13 chairman and TSB director
lead to a formal request to the ITU-T to host the OCAF (26
March)
• ITU-T representatives attend meeting with the OCAF (5 & 6
April) to clarify working arrangements and OCAF charter
issues with the objective to finalise the arrangements by end
of April
