    摘要： A method and system for transferring user equipment (UE) in a mobile communication system are disclosed. According to the method, a source core (CN) network determines to transfer a UE that it serves and sends a transfer instruction carrying UE transfer restriction information to the UE; an access network receives a transfer request that is sent by the UE according to the restriction information carried in the transfer instruction; the access network selects a target CN entity that is different from the source CN entity for the UE; and the UE is transferred to the target CN entity. The method and system provided by the present invention are applicable to user transferring between CN entities in any communication network. The transferring is initiated by a network side entity, and a more preferable CN entity is selected for the UE to provide a better service.

    摘要： 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.

    摘要： An emergency call method includes the following blocks: a User Equipment (UE) sends an emergency attach request that establishes an emergency indication to a System Architecture Evolution (SAE) network; the SAE network selects an emergency call service entity for the UE after receiving the emergency indication; the UE sends an emergency call request to the emergency call service entity after getting attached to the SAE network emergently; and the emergency call service entity establishes an emergency voice bearer, whereupon the UE makes an emergency call according to the established emergency voice bearer. Through the method for simulating a Circuit Switched (CS) emergency call by means of an emergency call service entity in the SAE network, the emergency call service can be implemented in the SAE or Long Term Evolution (LTE) packet network.

    摘要翻译： 紧急呼叫方法包括以下方框：用户设备（UE）向系统架构演进（SAE）网络发送建立紧急指示的紧急连接请求; SAE网络在接收到紧急指示后，为UE选择紧急呼叫业务实体; 在紧急连接SAE网络之后，UE向紧急呼叫业务实体发送紧急呼叫请求; 并且紧急呼叫服务实体建立紧急话音承载，由此UE根据建立的紧急话音承载进行紧急呼叫。 通过在SAE网络中通过紧急呼叫业务实体模拟电路交换（CS）紧急呼叫的方法，可以在SAE或长期演进（LTE）分组网络中实现紧急呼叫业务。
