Question 6/SSG - Harmonisation of evolving IMT-2000 systems

Reasons for study

A mission of the ITU-T SSG is to facilitate harmonization of evolving IMT-2000 systems. The SSG should provide a forum for open discussion of issues related to the global harmonization of IMT-2000 systems, which include interface and protocol requirements including:

  • Service Provisioning
  • Mobility Management (covered in Q.2/SSG and input to this Question)
  • Session Control (e.g. call control), and
  • Bearer Control (e.g. circuit mode, packet mode)

and issues not being addressed by external organizations (e.g., SDOs, etc.)

A major objective of the harmonization of IMT-2000 networks is the development of common network solutions that can facilitate cost-effective IMT-2000 network deployments based on the standardized open interfaces, stimulate the commercial uptake of IMT-2000 services, and foster global roaming across all evolving IMT-2000 systems.

Question

What is needed for harmonization of evolving IMT-2000 systems?

To provide seamless global roaming for IMT-2000 future Capability Set services that will include voice, high speed packet data, multimedia, and IP-based services, what are the network solutions that would facilitate harmonization of evolving IMT-2000 systems?

Task objectives

Specific task objectives include:

1) Establish co-operative working arrangement with external organisations (e.g. SDOs, etc.) to ensure that work under this question in ITU-T does not overlap with external organisations.

Expected Completion: On-going

2) Taking into account work progressing under Questions Q.3/SSG and Q.4/SSG, identify and study the degree of the harmonisation of existing IMT-2000 networks and document these in an appropriate manner.

First deliverable: 4Q2001

This task will be repeated regularly as new information is made available and for as long as there is a need.

3) Based on the output of Questions Q.3/SSG and Q.4/SSG, identify and study appropriate harmonisation issues of the existing IMT-2000 systems where harmonisation may be desired, and document these in an appropriate manner.

First deliverable: 2Q2002.

This task will be repeated regularly as new information is made available and for as long as there is a need.

4) Ensuring consistency with the ongoing work of Question Q.1/SSG, develop harmonisation proposals for evolving IMT-2000 systems, and document these in an appropriate manner for consideration by the Partnership Projects and SDOs as part of their evolution plans. This may include protocol aspects as deemed appropriate in the areas of:

  • Service Provisioning
  • Session Control (e.g. call control), and
  • Bearer Control (e.g., circuit mode, packet mode)

First deliverable: 4Q2002.

This task will be repeated regularly as new information is made available and for as long as there is a need.

Relationship to other IMT-2000 standardization activities in ITU-T and ITU-R

  • Signalling for IP-based services and BICC. - ITU-T SG 11
  • IMT-2000 and their evolution - (ITU-R)
  • The handbook being produced under Q.5/SSG in cooperation with ITU-D
  • ITU-T SGs 13 and 16, and others as appropriate

Relationship to other standardisation bodies outside ITU

  • Relevant SDOs, IETF.
