  4. ITU-R Working Party 8F • WP8F, replacing TG 8/1, is the global focal point for the continuing vision of next generation wireless services and systems, acting as a forum for user requirements and as a catalyst for translating those requirements into technical reality. • WP8F has the challenging task of supporting the near term needs of the IMT-2000 marketplace while exploring where we might go in the wireless world of the future. • Chairman • Mr. Stephen BLUST, USA • Vice-Chairpersons: • Mrs. Shumin CAO, China • Mr. Stuart COOKE, UK • Mr. Kyu-Jin WEE, Korea

  5. ITU-R WORKING PARTY 8F • WP8F’s charter is to: • be responsible for the overall system aspects of IMT-2000 • continue the global development of IMT-2000 • working with proponent organizations, partnership projects and standards development organizations • develop the vision of IMT beyond IMT-2000 • focus on terrestrial components • coordinate with ITU-R WP8D re satellite; and also with ITU-T and ITU-D • Included in the work assigned to WP8F are issues such as: • spectrum needs • higher data rate capabilities • Internet Protocol (IP)-based service needs of mobile systems • developing country needs

  12. ITU-T Special Study Group Vision Activities

  13. ITU-T Special Study Group on IMT-2000 and Beyond ITU-T Special Study Group on IMT-2000 and Beyond Liaison to/from ITU-R WP8F Working Party 1 Service and Interface Requirements for IMT-2000 and Beyond Working Party 2 Application and Inter-Working of IMT-2000 Working Party 3 Harmonization and Convergence of IMT-2000 Question 1 Service and network capability requirements and network architecture Question 2 Network-to-network interface (NNI) mobility management protocol Question 5 Participate in the preparation of a handbook on IMT-2000 (in cooperation with ITU-T and ITU-D) Question 7 Convergence of fixed and existing IMT-2000 systems • Notes: • Q.3 produces recommendations that are the network equivalents to ITU-R Recommendation M.1457 (RSPC) • The work of Q.1 is the network equivalent of the ITU-R WP8F Vision Working Group Question 3 Identification of existing and evolving IMT-2000 systems Question 6 Harmonization of existing IMT-2000 systems Question 4 Inter-working functions to be used with existing and evolving IMT-2000 systems

  14. Some Key Drivers from an ITU-T Special Study Group Perspective • Network-to-Network Interface • Mobility Management • Protocol requirements • Protocol development

  15. Network-to-Network Interoperability (NNI) CN - Core Network; core network may be IP-based IWF - Interworking Facility

  16. Specific Vision Activities of ITU-T SSG • Vision Report:Develop and maintain a long-term (focused around year 2010) vision in conjunction with ITU-R WP8F for future mobile service and network capabilities requirements 1st release of the document – 4Q 2001 • Gap analysis:Conduct and review a gap analysis between this vision and ongoing work in internal and external organisations towards this vision, in order to identify areas, if any, where the SSG can apply its expertise • Survey: Conduct a survey of external organizations: Questionnaire - Service and Network Capability Requirements

  17. Collaborative Efforts in Developing A Long-Range Vision for Systems Beyond IMT-2000 Including Wireless Multimedia and IP Requirements

  18. IMT-2000 Became and Is Now a Global Partnership • ITU-R ensures a global perspective on IMT-2000 for the developmental and evolution vision, for worldwide compatibility, for international roaming, for user needs, for baseline requirements, for core specifications, and fosters global consensus. • Partnership Projects ensure a global perspective on the technology developments and are a primary developer of the radio interface technical specifications. • SDO’s ensure regional and local suitability and applicability of the global core specifications. Their efforts result in IMT-2000 standards that are based upon the technical specifications produced by the Partnership Projects. • Recommendation ITU-R M.[RSPC] reflects this partnering of organizations and the division of work and responsibility. • Formal business arrangements between ITU-R and external organizations reflect the responsibilities and roles and ensure the integrity of ITU-R IMT-2000 standards and ITU processes.

  19. Organizations and Process for International Partnering in Development of IMT Requirements, Specifications, Standards, and Recommendations Market Organizations ITU-R Working Party 8F Vision Working Group CDMA Development Group UWCC UMTS Forum Operator Harmonization Group Content Providers Others Long-Term Perspectives IMT Concepts and Principles (ITU-R Recommendations) Market Research Mid-Term Perspectives Market Requirements and Drivers IMT Framework Concepts, Principles, and Requirements Externally Recognized Organizations (ITU-R Frameworks & Requirements Recommendations) Technology Proponents ( Partnership Projects and Others) IMT Radio Technology Working Group Specifications Proposal, Evaluation and SDOs Consensus Building Process IMT Standards ITU-R Recommendations Global Perspective with Regional and National Specifics Global Recognized Coordinated Standards Documents Global Perspective

  21. Collaborative ITU-R/ITU-T Work in Development of a Common ITU Vision for Systems Beyond IMT-2000 • There is agreement in both ITU-R WP 8F and ITU-T that there should be a single ITU vision of systems beyond IMT-2000. • ITU-T is working on developing material that is consistent with the ITU-R WP 8F Vision PDNR outline. • Publication mechanism for the joint vision of systems beyond IMT-2000 has not been decided.

  22. An Example of Why Collaboration is Needed: Current IMT-2000 IP-based Core Network Standardization Landscape TTA CWTS CWTS ETSI ITU-T Note: The fora identified in this diagram are not intended to be all inclusive. Other fora such as ETSI TIPHON, HYPERLAN, etc., are not shown but are not excluded. 3GPP 3GPP2 ARIB/ TTC TIA TTA T1 ARIB/ TTC cdma 2000 Evolution GPRS/UMTS/GERAN Evolution TMF Other Fora TeleManagement Forum 3G.IP Forum MWIF Standards Influencing Forums IETF Mobile Wireless Internet Forum Assertion: Network operators want, ideally, a common IP-based network architecture. However, there will not likely be such a common IP architecture in the near term, therefore operators want easilyinteroperable IP-based networks. Problem: Many fora are addressing IP-based core network requirements. Unfortunately, these fora are not addressing an IP-based internetworking solution.

  23. Operators Harmonization Group Request to ITU-T Special Study Group • OHG believes that a single global all IP network standard for IMT-2000 will provide maximum benefits to our customers such as global roaming and affordable handsets. • Even if both PPs agreed to have the same all-IP architecture, the systems will not be compatible unless the same protocols are used. • Levels of mobility: • Air interface mobility • Link-level mobility • Network-level mobility • The only organizations that can resolve the specific differences are the Partnership Projects themselves. • OHG recognizes that the SSG has responsibility for long term harmonization. • Recommends that OHG assist SSG in facilitating a meeting between the two PPs. Air interface and link level mobility my be hard to achieve because of the need to achieve backward compatibility

  24. Summary and Some Topics for Open Discussion • Collaborative work with external organizations is the norm for both ITU-R and ITU-T with the use of normative references. • Wireless Standards Development - A New Paradigm for the ITU. • Collaborative work on vision for systems beyond IMT-2000 between ITU-R and ITU-T has begun. • Increased collaboration with external organizations on multimedia and IP: • Formal liaisons • E-mail reflectors • Workshops • Joint experts group meetings • Other?? • Role of content providers - should there be one? • Need to “think outside the box” • ITU role in harmonization and convergence of multimedia services definitions and IP systems and networks
