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 user equipment corresponding to the IMSI sent by the source SGSN. The device includes an MSC server, an SGSN, an MME, and a BSC/RNC. The method and apparatus according to embodiments of the present invention, by applying for context information from a source SGSN by using an MME determined by an MSC server, are capable of ensuring that, in an rSRVCC handover process, the MSC server and the SGSN interact with the same MME, thereby avoiding a handover failure 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.
