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.

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 8 F 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 8 F Vision PDNR outline. • Publication mechanism for the joint vision of systems beyond IMT-2000 has not been decided.

An Example of Why Collaboration is Needed: Current IMT-2000 IP-based Core Network Standardization Landscape ETS I CWTS ARIB/ TTC 3 GPP ITU-T T 1 GPRS/UMTS/GERAN Evolution Problem: TTA ARIB/ TTC 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. TMF Other Fora Assertion: TIA 3 GPP 2 cdma 2000 Evolution CWTS TTA Note: Tele. Management Forum 3 G. IP Forum MWIF IETF Mobile Wireless Internet Forum Standards Influencing Forums 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 easily interoperable IP-based networks. Many fora are addressing IP-based core network requirements. Unfortunately, these fora are not addressing an IP-based internetworking solution.

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 Air interface and link level mobility my be hard to achieve because of the need to achieve backward compatibility – 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.

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
