•NGN has become a major aspect of the work ofthe ITU-T, reinforced by the positive outcomesof a number of ITU-T workshops and by thegrowing interest and involvement in NGN workin the Study Groups
•Study Group 13 responded by the setting up ofan NGN-2004 Project and by initiating intensivework on the definition of NGN and preparation ofa set of ‘foundational’ Recommendations onNGN

The ITU-T NGN ProjectThe ITU-T NGN Project
The aim of the NGN Project is to identify andcoordinate all ITU-T activities related to theestablishment of implementation guidelinesand standards for the realisation of a NextGeneration Network. A major task of theProject is to ensure that all elements requiredfor interoperability and network capabilitiesto support applications globally across theNGN are addressed by ITU-T standardisationactivities.

ITU-T Definition of a Next GenerationNetworkITU-T Definition of a Next GenerationNetwork
A Next Generation Network is a packet-based network able to provide servicesincluding Telecommunication Services andable to make use of multiple broadband,QoS-enabled transport technologies andin which service-related functions areindependent from underlying transport-related technologies.

It offers unrestricted access by users todifferent service providers.
It supports generalised mobility whichwill allow consistent and ubiquitousprovision of services to users.

An NGN is characterised by thefollowing fundamental aspectsAn NGN is characterised by thefollowing fundamental aspects
•Packet-based transfer
•Separation of control functions amongbearer capabilities, call/session, andapplication/ service
•Decoupling of service provision fromnetwork, and provision of openinterfaces
GSC-9, Seoul
•Support for a wide range of services,applications and mechanisms basedon service building blocks (includingreal time/ streaming/ non-real timeservices and multi-media)
•Broadband capabilities with end-to-end QoS and transparency
•Interworking with legacy networksvia open interfaces
GSC-9, Seoul
•Generalised mobility
•Unrestricted access by users todifferent service providers
•A variety of identification schemeswhich can be resolved to IP addressesfor the purposes of routing in IPnetworks
•Unified service characteristics for thesame service as perceived by the user
GSC-9, Seoul
•Converged services betweenFixed/Mobile
•Independence of service-relatedfunctions from underlying transporttechnologies
•Compliant with all regulatoryrequirements, for example concerningemergency communications andsecurity/privacy

Future activitiesFuture activities
•Further work on the NGN foundationalRecommendations in Study Group 13 andon specific NGN Recommendation in theother Study Groups
•Further development of the NGN Project toinclude all required new standards andrelease plans and to take account of anyrestructuring of the ITU-T Study Groups
GSC-9, Seoul
•Study Groups will include NGN issues intheir new questions for the new studyperiod
•Collaboration with other SDOs andregional standards organisations toensure harmonisation and globalisationof NGN through the focus of the ITU-T
GSC-9, Seoul
•Consideration of additional ways toconcentrate NGN standardisation effortsand to respond to the needs of industrye.g.
–setting up of one or more ‘Focus Groups’ onNGN
–increased project working in the ITU-T

Discussions with the OCAFDiscussions with the OCAF
•Initial contact with Open Communications Architecture Forumad hoc group (11 March) - ITU-T offers to host the Forum as aFocus Group
•Discussions with Study Group 13 chairman and TSB directorlead to a formal request to the ITU-T to host the OCAF (26March)
•ITU-T representatives attend meeting with the OCAF (5 & 6April) to clarify working arrangements and OCAF charterissues with the objective to finalise the arrangements by endof April
