GSC 9/GTSC_007 SOURCE: ITU-T TITLE: ITU-T NGN - Progress and Plans AGENDA ITEM: 5 CONTACT: Brian Moore, Email brian@bwmc. demon. co. uk, Tel/Fax +44 1206 762335 ITU-T NGN - Progress and Plans Brian Moore Lucent Technologies Chairman of ITU-T Study Group 13 GSC-9, Seoul 1

1. 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 2. 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 GSC-9, Seoul

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. GSC-9, Seoul

Role of Study Group 13 in the ITUT NGN project • Requirements and implementation scenarios for services and framework architectures • Generic technical work • Project development and management • Development of Profiles GSC-9, Seoul

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, Qo. S-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

1. 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) 2. Broadband capabilities with end-toend Qo. S and transparency 3. Interworking with legacy networks via open interfaces GSC-9, Seoul

1. Generalised mobility 2. Unrestricted access by users to different service providers 3. A variety of identification schemes which can be resolved to IP addresses for the purposes of routing in IP networks 4. 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. e 2 eqos: End-to-end Qo. S architecture for IP networks evolving into NGN • Y. 123. qos: A Qo. S 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 GSC-9, Seoul
