La présente invention concerne un procédé et un système d'inhibition de tempête de signalisation. Le procédé consiste en ce qui suit : un élément de réseau de commande identifie si un terminal se connectera bientôt au réseau fréquemment ou si le terminal se connecte au réseau fréquemment en surveillant le flux de service du terminal ; l'élément de réseau de commande transmet des paquets de contexte au terminal par la voie de service correspondant au flux de service lorsqu'il identifie que le terminal se connectera bientôt au réseau fréquemment ou que le terminal se connecte au réseau fréquemment ; l'élément de réseau de commande compte le trafic réel du terminal tout en continuant de transmettre les paquets de contexte au terminal, et arrête de transmettre les paquets de contexte au terminal quand le temps persistant pendant lequel le trafic réel du terminal est nul dépasse un temps de seuil prédéfini. La présente invention permet au terminal de diminuer la fréquence de lancement actif de la libération de la connexion de service, évitant ainsi que le terminal ne génère activement la tempête de signalisation et optimisant également ainsi le problème de la tempête de signalisation du terminal intelligent.
