Abstract
Techniques to support location services for a roaming mobile station are described. The mobile station may communicate with a serving mobile switching center (MSC) in a serving network. A roaming service provider (RSP) network may map an actual MSC identity (MSCID) of the serving MSC to a generic MSCID and may provide the generic MSCID to a home network. A home mobile positioning center (H-MPC) may map the generic MSCID to an Internet Protocol (IP) address of a mapping server within the RSP network and may send a location request message containing a mobile station identity (MSID) to the mapping server. The mapping server may determine a serving mobile positioning center (S-MPC) based on the MSID and may forward the message to the S-MPC. The mapping server may also receive a location response message from the S-MPC and may forward the message to the H-MPC.
