Providing a set of services to a multi-mode wireless mobile station that is able to operate over packet-switched and circuit-switched access networks

摘要

A set of services is from a multimedia network to a multi-mode mobile station that is able to operate over a packet-switched access network and a circuit-switched access network. Packet-switched call control messages are communicated between a node in the multimedia network and the multi-mode mobile station through the packet-switched access network when the multi-mode mobile station is attached to the packet-switched access network, where the packet-switched call control messages communicated through the packet-switched access network are used to provide the set of services. Packet-switched call control messages are communicated between the node in the multimedia network and the multi-mode mobile station through the circuit-switched access network when the multi-mode mobile station is attached to the circuit-switched access network, where the packet-switched call control messages communicated through the circuit-switched access network are used to provide the set of services.
