Abstract:
Embodiments of this application provide a CSFB method and apparatus. The method includes: learning, by a source access network device, that CSFB needs to be performed on a terminal, where performing the CSFB on the terminal includes moving the terminal from a first standard network to a second standard network; determining, by the source access network device before completing moving of the terminal from the first standard network to the second standard network, that a serving cell handover needs to be performed on the terminal in the first standard network; and performing, by the source access network device, the serving cell handover on the terminal, where the source access network device sends CSFB information to a target access network device in a process of the serving cell handover.

Claim (Index 16):
The apparatus according to  claim 14 , wherein:\n the first interface is further configured to: after the first interface sends the response message to the mobility management network element, and before the processor determines that the serving cell handover needs to be performed on the terminal in the first standard network, send a first handover request message to the mobility management network element, the first handover request message for triggering a packet switched (PS) handover on the terminal; and the processor is further configured to terminate the PS handover on the terminal after determining that the serving cell handover needs to be performed on the terminal, or the first interface is further configured to: after the first interface sends the response message to the mobility management network element, and before the processor determines that the serving cell handover needs to be performed on the terminal in the first standard network, send a first handover request message to the mobility management network element, the first handover request message for triggering a single radio voice call continuity (SRVCC) handover on the terminal; and the processor is further configured to terminate the SRVCC handover on the terminal after determining that the serving cell handover needs to be performed on the terminal.
