    • A user equipment (UE) communicating with a radio access network (RAN) sends to a network entity (e.g., an MSC/SGSN) a request for periodic reporting of the UE location to a client entity. After the request is approved, the MSC/SGSN sends to the RAN signaling to initiate periodic location reporting for the UE. The RAN may request a positioning center (e.g., a SAS) to send assistance data to the UE. The RAN may coordinate and control the periodic location reporting or may pass the control over to the positioning center. For each location reporting, the UE sends location information (e.g., measurements made by the UE or a location estimate computed by the UE) to the RAN. The SAS computes a location estimate if the UE sends measurements. The RAN then sends the location estimate for the UE to the MSC/SGSN, which forwards the location estimate toward the client entity.
    • 与无线电接入网络(RAN)通信的用户设备(UE)向网络实体(例如,MSC / SGSN)发送用于向客户端实体定期报告UE位置的请求。 在请求被批准之后,MSC / SGSN向RAN发送信令以发起针对UE的周期性位置报告。 RAN可以请求定位中心(例如,SAS)向UE发送辅助数据。 RAN可以协调和控制周期性位置报告,或者可以将控制传递给定位中心。 对于每个位置报告,UE向RAN发送位置信息(例如由UE进行的测量或由UE计算的位置估计)。 如果UE发送测量,则SAS计算位置估计。 RAN然后将UE的位置估计发送给MSC / SGSN,MSC / SGSN将位置估计转发给客户实体。
