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 SMPC. The mapping server may also receive a location response message from the S-MPC and may forward the message to the H-MPC.

L'invention concerne des techniques permettant de supporter des services de localisation pour une station mobile itinérante. La station mobile peut communiquer avec un centre de commutation mobile de desserte (MSC) dans un réseau de desserte. Un réseau de fournisseurs de service itinérant (RSP) peut établir une correspondance entre une identité de MSC réelle (MSCID) du MSC de desserte et une MSCID générique et peut transmettre la MSCID générique à un réseau domestique. Un centre de positionnement de mobile domestique (H-MPC) peut établit une correspondance entre la MSCID générique et une adresse de protocole Internet (IP) d'un serveur de correspondance dans le réseau RSP et peut envoyer un message de demande de localisation contenant une identité de station mobile (MSID) au serveur de correspondance. Le serveur de correspondance peut déterminer un centre de positionnement de mobile de desserte (S-MPC) sur la base de la MSID et peut transmettre le message au SMPC. Le serveur de correspondance peut également recevoir un message de réponse de localisation du S-MPC et peut transmettre le message au H-MPC.
