Question 5/19
Convergence of evolving IMT-2000 networks with evolving fixed networks
- Motivation
The work on Fixed / Mobile core network convergence which has been performed since WTSA-2000 should continue and include all aspects required for this convergence including a vast range of terminal/access network interfaces (both wired and wireless) so that seamless operation of services is achieved.
This Question shall be responsible for the Q.176x series of Recommendations.
- Question
Study items to be considered include, but are not limited to:
What new Recommendations or enhancement of existing (or new) Recommendations are required to specify a core network and its interfaces that can utilise various wired and wireless terminals so as to provide delivery of access independent services to the end users?
What new Recommendations or enhancement of existing (or new) Recommendations are required to ensure the support of services of public interest such as emergency call handling and lawful interception?
- Tasks
Tasks include, but are not limited to:
Taking into account work progressing under Question 3/19, identify and study the degree of the convergence of evolving IMT-2000 networks with evolving fixed networks and NGN in relation to seamless provisioning of services and document these.
This task will be repeated regularly as new information is made available and for as long as there is a need.
Develop convergence proposals for evolving IMT-2000 networks with evolving fixed networks in relation to seamless provisioning of services and document these for consideration by SDOs as part of their evolution plans.
This task will be repeated regularly as new information is made available and for as long as there is a need.
Identify and study architectural and network interface issues relating to converged core networks consistent with the long term network architecture as delivered by Question
1/19 to ensure capture of the convergence requirements, and document these
This task will be repeated regularly as new information is made available and for as long as there is a need.
An up-to-date status of work under this Question is contained in the SG 19 Work Program (http://www.itu.int/itudoc/itu-t/com19/workprog/05-08/sg19wprg.html)
