Question 2/19
Mobility Management
- Motivation
With the convergence of fixed and wireless networks, the convergence of telecommunication
and information technologies, and the foreseen ultimate migration to interoperable and
harmonized network architectures, there is an industry requirement to provide global roaming
and seamless mobility for the users of different access technologies and/or different operators
so that they can enjoy seamless services while moving within or across networks.
- Question
Study items to be considered include, but are not limited to:
What is needed to support global roaming and seamless mobility and delivery of services within or across networks for both systems beyond IMT-2000 and the NGN?
What mechanisms are required in this context to insure the support of services of public interest such as emergency call handling and lawful interception?
- Tasks
Tasks include, but are not limited to:
Identify or define the user and operator’s perspective of mobility management capabilities for both systems beyond IMT-2000 and the NGN
Develop the functional requirements for mobility management capabilities for both systems beyond IMT-2000 and the NGN
Develop the architecture (interrelationship) and definition of the functional entities required to provide mobility management capabilities for both systems beyond IMT-2000 and the NGN.
Develop the information flows and the timing of the flows between functional entities to provide the necessary mobility management capabilities for both systems beyond IMT-2000 and the NGN.
Develop the actions of the functional entities upon receiving an information flow necessary for mobility management capabilities for both systems beyond IMT-2000 and the NGN.
Allocate the functional entities to physical entities in order to determine which interfaces can use existing protocols or enhancements to existing protocols and which interfaces need protocol development for mobility management capabilities for both systems beyond IMT-2000 and the NGN.
For those interfaces requiring enhancements to existing protocols, provide the functional requirements to the standards body that develops the protocol.
For those interfaces requiring new protocols, determine the appropriate body for the protocol development, provide the functional requirements to that standards body, and if necessary develop the protocol under this question.
