    • Techniques for supporting location services with roaming are described. A mobile station interacts with a home mobile positioning center (H-MPC) in a home network for location services even when roaming. The mobile station communicates with a visited network for a data session and receives a request for its location. The mobile station sends first information (e.g., SID and NID) indicative of its current network location to the H-MPC. The H-MPC determines a serving mobile positioning center (S-MPC) in the visited network based on the first information. The S-MPC determines a serving position determining entity (S-PDE) in the visited network based on the first information. Depending on the selected positioning method, the H-MPC may receive an S-PDE address or a position estimate of the mobile station from the S-MPC and may forward this information to mobile station. The mobile station may communicate with the S-PDE for positioning using the S-PDE address.
    • 描述了用于支持漫游的位置服务的技术。 即使在漫游时,移动台也与归属网络中的家庭移动定位中心(H-MPC)进行交互以进行定位服务。 移动台与受访网络进行数据会话通信,并接收对其位置的请求。 移动台向H-MPC发送指示其当前网络位置的第一信息(例如,SID和NID)。 H-MPC基于第一信息确定被访问网络中的服务移动定位中心(S-MPC)。 S-MPC基于第一信息确定访问网络中的服务位置确定实体(S-PDE)。 根据选择的定位方法,H-MPC可以从S-MPC接收移动台的S-PDE地址或位置估计,并将该信息转发到移动台。 移动台可以使用S-PDE地址与S-PDE通信进行定位。
