Reasons for the question

Convergence of fixed and mobile networks and ultimately migration to interoperable and harmonised network architectures to provide services transparently to the users across different access arrangements is becoming an industry requirement.

As part of the evolutionary process, the support of mobility is being developing in existing and future fixed networks.

The support of mobility in "IMT2000 and beyond" networks is being considered by a Special Study Group in the ITU-T.

Close co-operation and collaboration between ITU-T and external SDOs and forums will be required to ensure that standardisation work is not duplicated in ITU-T.

Question

What new bearer independent signalling application protocols, or enhancements to existing protocols are needed to support mobility in existing a future fixed networks?

Task objectives

The main tasks are as follows:

1) Examine the signalling protocol requirements produced by the IMT-2000 Special Study Group and the VHE Question 2/11 and identify the mobility features in the fixed network requiring protocol development.

Expected completion: Ongoing.

2) In collaboration with the appropriate requirements questions, define any new protocols or enhancements needed for the fixed network to support the features identified.

Expected completion: Ongoing.

3) Produce the necessary information for Protocol Implementation Conformance Statements (PICS) with the support of the testing question, if required. To assist the test generation the extensive usage of formal description techniques (e.g. SDL, ASN.1) is encouraged.

Expected completion: Ongoing.

NOTE - Task completion dates are in accordance with task requirements.
