Lead SG on IMT-2000 and beyond and for mobility

Primary responsibility within ITU‑T for overall network aspects of IMT‑2000 and beyond

– Work plan

– Migration path from existing IMT-2000 systems 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

29

Summary of Mandate of ITU-T SSG (2 of 2)

• In addition, will study:• 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 needed

• Work with ITU-D to assist developing countries in 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 specifications or interim Recommendations

• Make use of provisional working procedures specific to SSG

Efficiently develop high-quality, global, consensus-based recommendations (standards) in its core competency areas on a market-driven and timely basis

Facilitate the interoperability of networks and services

35

Draft ITU-T Strategic Plan for 2003-2006Mission - continued

Be able to develop recommendations that may have regulatory or policy implications

Be flexible and constantly look for ways to improve

Give appropriate consideration to the particular needs of developing countries

Cooperate and, where appropriate, collaborate with others so as not to duplicate effort

36

Draft ITU-T Strategic Plan for 2003-2006Strategies/Processes

bottom-up mode of operating and production of work (rather than top-down),

flexibility in responding to market demands, ongoing review of the Strategic Plan,

proposing adjustments as needed, through TSAG, monitoring the performance

of the Sector against identified milestones,

37

Draft ITU-T Strategic Plan for 2003-2006Strategies/Processes - continued

development and strengthening of the linkage among financial, strategic, and operational planning,

clear and transparent working methods and processes, to encourage transparency, inclusiveness, and representation of a broad range of participants and views,

an environment in which interested parties can work together in partnership effectively and efficiently,

development and execution of an aggressive plan to communicate the value of the ITU-T, stressing its global recognition and credibility and the high quality of its Recommendations, as well as its willingness to change,

38

Draft ITU-T Strategic Plan for 2003-2006Strategies/Processes - continued

working with ITU-D with special attention to telecommunication development in developing countries, including supporting ITU-D’s 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.

39

Draft ITU-T Strategic Plan for 2003-2006Relationship 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.

40

Possible Items for Consideration

IP-based networks and their interconnection with telecommunication networks;

IP cablecom project; establishment of GII; IMT-2000 and mobility; e-business and e-commerce; reform of accounting rates and tariff studies; MEDIACOM-2004 project and related multimedia activities; security aspects of networks and services; optical transport network; access networks enhancements with xDSL techniques; numbering and routing; network performances and quality of services; protocols for new services and intelligent networks.
