| 摘要 |
User equipment (UE), for communicating wirelessly with communication networks, is disclosed, the UE being adapted so as to be capable of voice communication with communication networks via a plurality of mechanisms, the plurality of mechanisms comprising at least one packet-switched (PS) mechanism and at least one circuit-switched (CS) mechanism. The UE is further adapted, when at a location at which the UE is able to communicate wirelessly with a particular communication network, to communicate with the network to determine which voice communication mechanisms the network is adapted to use. The UE is further adapted to select a voice communication mechanism according to a result of the determination and according to said plurality of mechanisms the UE is adapted to use, and to provide voice communication with the network via the selected mechanism. A corresponding method is disclosed. |
