<p>A system, an apparatus, and a method for user service handover are provided. The handover system includes a Packet Switched (PS)-domain Access Network (AN), a Mobile Switching Center (MSC), a User Equipment (UE), a packet access unit, and optionally, a Circuit Switched (CS)-domain AN. The packet access unit sets up a signaling channel between the PS-domain AN in the PS domain and the MSC in the CS domain, and manages the bearer between the UE and the MSC. The PS-domain AN processes the handover to the CS-domain area or the PS-domain area. The CS-domain AN processes the handover to the CS-domain area or the PS-domain area. The MSC processes the handover from the PS-domain AN or the handover to the PS-domain AN. Through the present invention, the service handover is enabled under control of the MSC; when the user performs a call, the service handover is enabled between a PS-domain area and a CS-domain area, and therefore, the operators can fully use the PS-domain network coverage to provide more continuous services for the user, and improve the network utilization efficiency.</p> |
