  1. GSC9/GTSC_007 ITU-T NGN - Progress and Plans Brian Moore Lucent Technologies Chairman of ITU-T Study Group 13 GSC-9, Seoul 1

  2. 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 GSC-9, Seoul

  3. 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

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

  5. GSC-9, Seoul

  6. ITU-T Definition of a Next Generation Network A Next Generation Network is a packet-based 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 transport-related technologies. GSC-9, Seoul

  7. It offers unrestricted access by users todifferent service providers. It supports generalised mobility which will allow consistent and ubiquitous provision of services to users. GSC-9, Seoul

  8. 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

  9. 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-to-end QoS and transparency • Interworking with legacy networks via open interfaces GSC-9, Seoul

  10. 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

  11. 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

  12. 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

  13. 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

  14. 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 Ethernet-based IP access network GSC-9, Seoul

  15. 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

  16. 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

  17. 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

  18. 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
