ITU-T Special Study Group IMT-2000 and Beyond

This study group is focused on network aspects of IMT-2000 and beyond, including wireless internet, mobility management, and mobile multimedia functions. It aims to collaborate with various organizations, enhance existing ITU-T recommendations, and facilitate global cooperation. The group's achievements include establishing strong relationships with ITU-R, ITU-D, 3GPP, and OMA, as well as contributing to long-term visions and frameworks for future network development. The study group also emphasizes globalizing regional solutions and promoting efficient cooperation among stakeholders in the telecommunications industry.

  3. Terms of Reference - General • WTSA-2000 Res. 2 - General Areas of Study: • Responsible for studies relating to network aspects of IMT-2000 and beyond, including wireless Internet, convergence of mobile and fixed networks, mobility management, mobile multimedia functions, internetworking, interoperability and enhancements to existing ITU T Recommendations on IMT-2000.

  4. Terms of Reference - Lead SG • WTSA-2000 Res. 2 - Lead Study Group: • IMT-2000 and beyond • Mobility

  5. Terms of Reference - Guidance • WTSA-2000 Res. 2 - Points of guidance: • Collaborate with ITU R WP 8F • Assist developing countries in consultation with ITU-D • Investigate and recommend modifications to Provisional Working Procedures (Rec. A.9) • Maintain strong cooperative relations with external SDOs and 3GPPs to allow for normative referencing in ITU T Recs. of mobile network specifications developed by those organizations • 4 Questions assigned but recognized as needing re-work within SSG

  6. Applying the Res. 2 Guidance EMPHASIS ON: • Collaboration • Cooperation • Partnering BUT NOT: • Duplicationof work Revolution from IP infrastructure and Beyond 3G Evolution from 2G systems 2G Revolution from subscriber service expectations

  7. SSG Management Team • Larger than usual • Strength in diversity: • viewpoints from vendors, operators and regulators • viewpoints from developed and developing countries

  8. SSG Management Team

  9. Study Group Organization • SSG originally met as three WPs: • WP 1: Service and Interface requirements for IMT 2000 and Beyond (2 Questions) • WP 2: Application and Interworking of IMT 2000 Systems (3 Questions) • WP 3: Harmonization and Convergence of IMT 2000 Systems (2 Questions) • Nov 2002: discussed efficiency • flatten organization: no WPs and Rapporteurs to report directly to the closing plenary • Q.8/SSG always met separately

  10. SSG Work Structure: 8 Qs End user experience consistency Inter-system mobility management SSG Key future core network characteristics Q.2 & Q.6/SSGMobility Mgmt & Harmonization For consideration by: Q.1/SSGVision Operator Inputs Q.3/SSGID Systems Q.7/SSGConvergence Q.5/SSGHandbook Leveraging infrastructure Globalize regional solutions Q.8/SSGProcedures Work completed, passed to TSAG Helping the decision process Q.4/SSGInterworking No inputs

  11. Statistics (I) - Documents • 8 SG meetings and 1 WP meeting • 32 Rapporteurs meetings • 10 face-to-face • 16 electronic • 6 conference calls • Approx. 1800 documents handled: • 230 (220 delayed) contributions to SSG meetings • 1006 TDs at SSG meetings (excluding revisions) • 552 documents at Rapporteur Meetings

  12. Statistics (II) - Participation Dec 2000 Geneva May 2001 Geneva Aug 2001 Rio de Janeiro May 2002 Ottawa Nov 2002 Geneva Jun 2003 Geneva Nov 2003 Geneva Apr 2004 Moscow

  13. Statistics (III) • 9new Recommendations approved • 4 Questions assigned by WTSA-2000 • 8 new or revised Questions developed during study period • 5 Questions proposed for next period • continuation of established work • no inputs: drop topic • recommend any future work on working procedures, types of deliverable, etc., be assigned to TSAG, not a technical study group

  14. Highlights of achievements (I) • Overcame early resistance to taking any substantive role in 3G mobile networks • Established strong relationships: • ITU-R WP 8F • ITU-D BDT and Q.18/2 • 3GPP and its OPs • 3GPP2 and its OPs • initiated ITU relationship with OMA

  15. Highlights of achievements (II) • ITU-R WP 8F: coordinated and consistent vision for future: • ITU-R Rec. M.1645 “Framework and overall objectives of the future development of IMT-2000 and systems beyond IMT-2000” • ITU-T Rec. Q.1702 “Long-termvision of network aspects forsystems beyond IMT-2000” • ITU-T Rec. Q.1703 “Service andNetwork Capabilities Frameworkof Network Aspects for Systems Beyond IMT-2000”

  16. Highlights of achievements (III) • ITU-D Q.18/2 • Close cooperation with BDT on Handbook on “Deployment of IMT-2000 Systems” • Supported Q.18/2 work on development of “Guidelines on the Smooth Transition of Existing Mobile Networks to IMT-2000 for Developing Countries”

  17. Highlights of achievements (IV) • Globalization of 3G • 3GPP: ITU-T Recs. in Q.1741-series:“IMT-2000 references to release 99, 4, 5of GSM evolved UMTS core network” • 3GPP2: ITU-T Recs. in Q.1742-series:“IMT-2000 references (approved as of mid-2002, 2003, 2004) to ANSI-41 evolved core network with cdma2000 access network”

  18. Highlights of achievements (V) • OMA • SSG initiated relationship with ITU-T • IPR policy issue for referencing under Recs. A.4, A.5 resolved: • OK to reference all OMA specifications approved after 31 Dec 2004 • will need to do case-by-case consultation to verify referencing for earlier specifications

  19. Workshops & Seminars • Seminar: “IMT-2000 and Beyond Systems” • 6 Sep 2001 / Rio de Janeiro / ~180 participants • Seminar: “IMT-2000 and Systems Beyond” • 28 May 2003 / Ottawa / ~300 participants • Workshop: "Next Generation Networks: What, When and How? Encompassing Services, Transport Convergence, mobility issues and more...” (with SGs 11, 13) • 9-11 Jul 2003 / Geneva / ~177 participants

  20. Future Work (I) • Mobility is a key dimension of future telecommunications • mobile subscribers outnumber fixed subscribers • technology advances mean more capability at less cost than ever before • Promote harmonizationof IMT-2000 Family members • mobility management a key area and opportunity • increased interoperability and compatibility

  21. Future Work (II) • Continue globalization of regional efforts • through effective cooperation and collaboration • Promoteconvergence of mobile and fixed networks as part of NGN studies • mobile no longer just another access technology • Support for developing countries • Handbook, Guidelines, Seminars, Workshops

  22. Conclusion • SSG has re-established ITU-T as a 3G player, but there is more to be done • ITU-T future: Next Generation Networks • must address all dimensions to achieve implementable and deployable results • architecture, signalling, mobilityneed to be strongly connected and coordinated • opportunity for WTSA to set up structure and mandates to support success of NGN studies
