Systems and methods for determining the home network carrier associated with a mobile station and authorizing the provision of services to the mobile station using centralized storage of mobile station and home network information. In one embodiment, when a roaming mobile station attempts to access services, identifying information for the mobile station is used by a local server to query a centralized DNS server that stores a mapping of mobile station identifying information to corresponding home networks. The centralized DNS server returns an identification of the home network of the roaming mobile user, and the home network then determines whether to grant or deny the mobile station access to the local network. The mobile station identifying information may comprise an MSID such as an MIN, IRM or IMSI, which may serve as part of the address for the query to the centralized DNS server.

L'invention porte sur des systèmes et sur des procédés de détermination du support de réseau domestique associé à une station mobile et d'autorisation de la fourniture de services à la station mobile au moyen d'une mémoire centralisée de station mobile et des informations du réseau domestique. Selon un mode de mise en oeuvre, lorsqu'une station mobile itinérante tente d'accéder à des services, les informations d'identification contenues dans la station mobile sont utilisées par un serveur local pour interroger un serveur DNS centralisé qui stocke une table des informations d'identification de la station mobile dans des réseaux domestiques correspondants. Le serveur DNS centralisé renvoie une identification du réseau domestique de l'utilisateur du mobile itinérant, et le réseau domestique détermine ensuite s'il faut accorder ou refuser l'accès au réseau local de la station mobile. Les informations d'identification de la station mobile peuvent comprendre un MSID tel qu'un MIN, IRM ou IMSI qui peuvent servir en partie d'adresse pour l'interrogation du serveur DNS centralisé.
