Abstract
A handover method includes an evolved mobile switching center (eMSC) that receives a relocation request from a first network and forwards the relocation request to a second network requesting the second network to establish its own media plane association. The eMSC establishes a media plane association with the second network. The eMSC instructs a user equipment (UE) to access the second network. With the handover method, the UE may be handed over between different networks by using the eMSC. A method for reattaching a UE to the eMSC is also provided so that the UE can be reattached to a target eMSC when the eMSC to which the UE is attached is changed. A handover apparatus and a handover system are also provided.
