Abstract

A method, an apparatus, and a system for implementing User Equipment (UE) handover are disclosed. A Mobility Management Entity (MME) obtains address information of a serving Interworking Function (IWF) by interacting with a function entity in a network and notifies the IWF to process handover according to the obtained IWF address information, so that the MME is capable of obtaining the address information of the serving IWF. Therefore, the normal proceeding of a UE handover procedure in a Circuit Switched over Packet Switched (CSoEPS) scenario is ensured.
