Techniques for supporting location-based services (LBS) by a removable module are described. A set of messages (e.g., commands and events) may be defined to support location-based services by the removable module. In one design, the removable module may send a first message (e.g., a Get Position&#x2014;Request message) to a terminal to request for location information. The first message may be sent for an LBS application running on the removable module. The removable module may thereafter receive a second message (e.g., a Get Position&#x2014;Response message) with the requested location information from the terminal. The removable module may execute a task for the LBS application based on the location information. The task may include reporting the location of the terminal, initiating a voice call, sending an SMS message, displaying a menu on the terminal, sending a report for tracking of the terminal, etc.

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.
