Abstract
The present invention discloses a method and a device for handover to a serving network. The method includes: receiving a first Handover Request sent by a BSC/RNC; sending a second Handover Request to a target MME according to the first Handover Request, where the second Handover Request includes an IMSI and first information for determining a source SGSN so that the MME sends a Context Request message including the IMSI to the source SGSN and receives context information of a UE that corresponds to the IMSI and is sent by the source SGSN. Thereby avoiding a handover failure which is caused because the MSC server and the SGSN select different MMEs, and further synchronizing PS and CS handover processes, improving handover accuracy and efficiency, and enhancing user experience.
