摘要:
A domain transferring method for the single radio voice call continuity, a UE accesses via an LTE/SAE network, and sets up an IMS session anchored at a VCC AS with a remote node; when an S-IWF receives a handover request used to transfer the session to make the session access from a CS domain, the method comprises: the LTE/SAE network sends a handover command to the UE, the UE sends a handover complete message to a target access device after receiving the handover command; after the UE sends the handover complete message, or after the S-IWF receives the handover complete message, a release session notification message is sent to a VCC AS; after receiving the session release notification message, the VCC AS releases the session resources of the session.
