Method and apparatus for supporting location services for a roaming mobile station
First Claim
1. A method of communication comprising:
- obtaining a first address of a first network entity for a first communication protocol;
mapping a second address of a second network entity for a second communication protocol; and
exchanging messages with a third network entity via the second network entity using the second address,wherein the exchanging messages with the third network entity comprises exchanging messages with the third network entity for location services for a mobile station roaming in a serving network different from a home network, and wherein the second network entity resides in a roaming service provider (RSP) network different from the serving and home networks.

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.
