A method and apparatus for caching mobile station (110) location information comprising a gateway packet switch node (150) for receiving and transmitting data packets between a plurality of visiting packet switch nodes (130) and at least one communication network (175) and a cache memory (165) located within the gateway packet switch (150) for caching location information received with a data packet from a transmitting mobile station (110). A communication packet, containing information pertaining to the location of a transmitting mobile station (110) is received (230) by the gateway packet switch node (150). The location information is extracted (250) from the received communication packet and cached (260). When an incoming data packet is received (300) by the gateway packet switch node (150), a determination is made (310) as to whether the location information for the destination mobile station (110) is stored within the cache (165). If the location information is stored within the cache (165) the location information is retrieved (340) from the cache (165) and the data packet is routed (350) to the mobile station (110). Otherwise, the location information is retrieved (320) from a home location register (197) and the data packet is routed (330) to the mobile station (110).
L'invention concerne un procédé et un dispositif permettant de mettre en antémémoire une information de localisation de station mobile (110). On utilise un noeud de commutation de paquets passerelle (150) pour la réception et la transmission de paquets de données entre plusieurs noeuds de commutation de paquets visiteurs (130) et au moins un réseau de communication (175) et une antémémoire (165) située dans le commutateur de paquets passerelle (150), ce qui permet de mettre en antémémoire l'information de localisation reçue avec un paquet de données depuis la station d'émission mobile (110). Un paquet de communication contenant l'information de localisation de la station d'émission mobile (110) est reçu (230) par le noeud de commutation de paquets passerelle (150). L'information de localisation est extraite (250) du paquet de communication reçu et mise en antémémoire (260). Lorsqu'un paquet de données entrant (300) est reçu par le noeud de commutation de paquets passerelle (150), le système détermine (310) si l'information de localisation pour la station mobile de destination (110) est mise en antémémoire (165). Si tel est le cas, l'information de localisation est extraite (340) de l'antémémoire (165), et le paquet de données est acheminé (350) vers la station mobile (110). Sinon, ladite information est extraite (320) d'un enregistreur de localisation nominal (197), et le paquet de données est acheminé (330) vers la station mobile (110).
