A method and system for transferring a user equipment (UE) in a mobile communication system are provided. The method includes the following steps. A source core network (CN) element determines to transfer the UE that it serves and sends a transfer instruction carrying UE transfer restriction information to the UE. The UE sends a transfer request according to the restriction information carried in the received transfer instruction. An access network selects a target CN element which is not the source CN element for the UE and transfers the UE to the target CN element. The method and system provided by the present invention are applicable to user transferring between CN entities in any communication network, for example, in an evolved network, universal mobile telecommunication system (UMTS) network, post-evolved network, network where a UMTS network and an evolved network coexist, and coexistence network in other forms. The method and system of the present invention are initiated by the network side, and a more preferred serving CN element is selected for the user according to a certain mechanism, so as to provide a better service for the user of the UE. |
