towards systems beyond IMT-2000 - Long term common IP-based architecture
- Near term IP-based internetworking
- Overview road map
- Interworking functions, if not done elsewhere
29Summary of Mandate of ITU-T SSG (2 of 2)

- Harmonization of IMT-2000 Family members as they
evolve beyond IMT-2000 - Evolution of network aspects utilizing IMT-2000
RTTs as FWA - Network aspects of convergence of fixed and
wireless networks - Standardization of IMT-2000 interfaces where

applyingIMT-2000 - Collaborate with ITU-R 8F (radio) and 8D
(satellite) - Strong cooperative relations and complementary
programs with SDOs, 3GPPs - May develop and approve Recommendations
- may investigate and make proposals to TSAG on
alternative types of output and associated
approval process, e.g., normative technical

38Draft ITU-T Strategic Plan for 2003-2006Strategie
s/Processes - continued
- working with ITU-D with special attention to
telecommunication development in developing
countries, including supporting ITU-Ds efforts
to improve access to the Information Society in
developing countries, - offering an organization that is attractive to
industry entities as a place to do their
standardization development work, and - willingness to change.
39Draft ITU-T Strategic Plan for 2003-2006Relations
hip with other standardization bodies
- foster awareness within ITU-T of the work done by
other bodies (such as SDOs, forums and
consortia), - coordinate and cooperate with such groups in
order to reduce duplication, avoid
inconsistencies, and assure that ITU-T work
provides added value, - continue to participate in appropriate
coordinating bodies, - coordinate and cooperate with the
Radiocommunication and Telecommunication
Development Sectors, and with the General
Secretariat and officials of the Union.
