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

release of the document – 4Q 2001
•
Gap analysis: Conduct and review a gap analysis between this

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 IMT2000 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 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.

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.
