Abstract
The present invention provides a method, device, and system for processing reverse single radio voice call continuity. The method includes, before handing over a voice service from a CS domain network to a PS domain network, preconfiguring, in the PS domain network by a UE, information about resources needed for the voice service handover; and in the process of handing over, by the UE, the voice service from the CS domain network to the PS domain network, establishing a forwarding channel between a first network element of the PS domain and a second network element of the CS domain by using the preconfigured information about resources, where the forwarding channel is configured to forward voice service data between the UE and a peer UE after the UE accesses the PS domain network.
