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:
Duplication of work
Revolution from IP infrastructure 3G
and Beyond
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 Operator Inputs
Inter-system mobility management
End user experience consistency
SSG
Key future core network characteristics
Q.2 & Q.6/SSG Mobility Mgmt &
Harmonization
For consideration by:
Q.1/SSG Vision
Operator
Inputs
Q.3/SSG ID Systems
Q.7/SSG Convergence
Q.5/SSG Handbook
Globalize regional solutions
Leveraging infrastructure
Q.8/SSG Procedures
Work completed, passed to TSAG
Helping the decision process
Q.4/SSG Interworking
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 documents handled:
230 (220 delayed) contributions to SSG meetings
1006 TDs at SSG meetings (excluding revisions)
552 documents at Rapporteur Meetings

13. Statistics (III) 9 new 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-term vision of network aspects for systems beyond IMT-2000”
ITU-T Rec. Q.1703 “Service and Network Capabilities Framework of 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, 5 of 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 harmonization of 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
Promote convergence 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, mobility need to be strongly connected and coordinated
opportunity for WTSA to set up structure and mandates to support success of NGN studies
