Patent

CA 2301674

In connection-oriented switching of packet data in known mobile communications systems, resources of the transmission path between the serving node (SGSN) and the radio network subsystem (RNS) and memory resources of the radio network subsystem are reserved unnecessarily due to the burst-like nature of packet data. Thus the transmission network's limited address space and the radio network subsystem's management resources are consumed. The invention concerns such connection management in a mobile communications system, which is suitable for packet-switched data transmission. The method according to the invention is characterized in that the logical connection between the serving node (SGSN) and the radio network subsystem (RNS) is released, so that the logical connection between the serving node (SGSN) and the mobile station (MS) remains, and the released logical connection is reconnected, when relaying of user data starts.

Dans les systèmes de télécommunication à commutation par paquets en mode connecté connus, les ressources de la voie de transmission entre le noeud de service (SGSN) et le sous-système du réseau de radiocommunication (RNS) sont réservées inutilement en raison de la nature des paquet de données, dont l'émission se fait par rafales. Ceci entraîne l'utilisation de l'espace adresse limité du réseau de transmission et des ressources de gestion du sous-système du réseau de radiocommunication. L'invention concerne un procédé de gestion de connexion dans un système de radiocommunication mobile qui convient pour la transmission à commutation par paquets. Ce procédé est caractérisé en ce que la connexion logique entre le noeud de service (SGSN) et le sous-système du réseau radio (RNS) est libérée de manière que la connexion logique entre le noeud de service (SGSN) et la station mobile (MS) est maintenue, et la connexion logique libérée est reconnectée lorsque la transmission des données utilisateur démarre.
