本步骤中, 移动管理网元接收到 UE发送的附着请求消息之后, 为 UE 建立上下文, 记录 UE处于等待寻呼的状态。 上述 UE的上下文可以通过 UE 的国际移动用户识别码( International Mobile Subscriber Identity,简称 IMSI ) 进行标识, 如果无法获取 UE的 IMSI , 则移动管理网元也可以分配一个唯一 的内部索引进行标识。移动管理网元可以在上述 UE的上下文中记录步骤 401 中基站设备上报的 UE的位置信息和移动管理网元接收到步骤 401 中的附着 请求消息之后为 UE分配的临时标识。 具体地, 移动管理网元可以为多个 UE 分配相同的临时标识,例如: 移动管理网元可以为处于相同位置区的所有 U E 分配相同的临时标识; 或者移动管理网元还可以为处于相同位置区一定数量 的 UE (例如: 500个 UE )分配相同的临时标识。 In this step, after receiving the attach request message sent by the UE, the mobility management network element establishes a context for the UE, and records that the UE is in a state of waiting for paging. The context of the UE may be identified by the UE's International Mobile Subscriber Identity (IMSI). If the UE's IMSI cannot be obtained, the mobility management NE may also be assigned a unique internal index for identification. The mobility management network element may record, in the context of the foregoing UE, the location information of the UE reported by the base station device in step 401 and the temporary identifier allocated to the UE after the mobility management network element receives the attach request message in step 401. Specifically, the mobility management network element may allocate the same temporary identifier to multiple UEs, for example: the mobility management network element may allocate the same temporary identifier to all UEs in the same location area; or the mobility management network element may also be in the same location. A certain number of UEs (for example: 500 UEs) are allocated the same temporary identity.
在 UTRAN/GERAN中 , SGSN可以在上述 UE的上下文中记录步骤 401 中基站控制器( Base Station Controller,简称 BSC ) /无线网络控制器( Radio Network Controller, 简称 RNC )上艮的路由区标识( Routing Area Identity, 简称 RAI )和 SGSN为 UE分配的分组临时移动用户标识( Packet Temporary
Mobile Subscriber Identity, 简称 P-TMSI )。 In UTRAN/GERAN, the SGSN may record the routing area identifier of the Base Station Controller (BSC)/Radio Network Controller (RNC) in step 401 in the context of the UE. Area Identity (RAI) and the SGSN group temporary mobile subscriber identity assigned to the UE (Packet Temporary Mobile Subscriber Identity, referred to as P-TMSI).
