Abstract

La présente invention porte sur un procédé et un appareil pour déclencher un équipement utilisateur. Le procédé consiste à : transmettre à l'équipement utilisateur un message de strate non d'accès (NAS) qui véhicule une adresse de déclenchement utilisée pour la communication entre un serveur et l'équipement utilisateur (S110) ; recevoir un message de déclenchement dont l'adresse IP de destination est l'adresse de déclenchement (S120) ; transmettre le message de déclenchement à l'équipement utilisateur par l'intermédiaire d'une passerelle de desserte (SGW), de façon à établir, selon le message de déclenchement, la connexion de communication avec le serveur par l'équipement utilisateur (S130). L'appareil comprend un premier module de transmission, un module de réception et un second module de transmission. Grâce au procédé et à l'appareil de l'invention, par configuration, pour l'équipement utilisateur, d'une passerelle de réseau de données par paquets et de l'adresse de déclenchement du serveur pour la communication entre le serveur et l'équipement utilisateur, lorsqu'il est nécessaire de déclencher l'équipement utilisateur pour une communication, le serveur peut déclencher l'équipement
