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. A reverse SRVCC handover process in this embodiment is implemented without the need of waiting for completion of an access transfer procedure. This ensures good continuity performance of the voice service in the reverse SRVCC handover and also ensures that the voice service after the handover is capable of achieving good quality of the voice service.
