Abstract
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.
