Telecommunications system and method

摘要

A telecommunications system provides mobile internet protocol related communications services to mobile nodes via a plurality of access networks that each include an access gateway, a mobility manager operable to receive link quality messages from the mobile nodes providing an indication of a currently available link quality from an access network with which the mobile node is currently affiliated. The mobility manager is also operable to receive application server messages from the application server for managing the communications service with respect to the communications session level. The mobility manager directs a change of affiliation of a first mobile node between one of a first of the access networks and a second of the access networks to the other of the first and second access networks, or a change of communications session level of the first mobile node.
