Title
(EN) METHOD FOR MANAGING MOBILITY IN A TELECOMMUNICATIONS NETWORK, AND MOBILITY SERVER THEREFOR
(FR) PROCEDE DE GESTION DE MOBILITE DANS UN RESEAU DE TELECOMMUNICATIONS, ET SERVEUR DE MOBILITE POUR LA MISE EN OEUVRE DU PROCEDE
Abstract
(EN) The invention concerns a network comprising several sub-networks (11-13) equipped with mobility servers (8) operating in accordance with an application layer signalling protocol. For a specific mobile user, one of the sub-networks (11) constitutes a nominal sub-network (9) containing a first information locating the user. When the mobile user is located with an access point (7) connected to a visited sub-network (12), the first locating information designates the mobility server of said visited sub-network, the sub-network mobility server holds in a register of visitors (10) a second information locating the mobile user, enabling him to transmit data through said access point, and each flow of information addressed to or originating from the mobile user, in the context of communication with a remote correspondent, is addressed to the visited sub-network mobility server.
(FR) Le réseau comporte plusieurs sous-réseaux (11-13) équipés de serveurs de mobilité (8) fonctionnant selon un protocole de signalisation de couche application. Pour un utilisateur mobile donné, l'un des sous-réseaux (11) constitue un sous-réseau nominal et est équipé d'un registre nominal (9) contenant une première information de localisation de l'utilisateur. Lorsque l'utilisateur mobile est localisé auprès d'un point d'accès (7) relié à un sous-réseau visité (12), la première information de localisation désigne le serveur de mobilité de ce sous-réseau visité, le serveur de mobilité du sous-réseau visité tient dans un registre de visiteurs (10) une seconde information de localisation de l'utilisateur mobile, permettant de lui transmettre des informations à travers ledit point d'accès, et chaque flux d'information destiné à ou provenant de l'utilisateur mobile, dans le cadre d'une communication avec un correspondant distant, est adressé au serveur de mobilité du sous-réseau visité.
