Abstract

L'invention concerne un procédé et un appareil permettant de mettre en œuvre un traitement de connexion de liaison. Le procédé comprend les étapes suivantes : lorsqu'une réponse à une demande, provenant d'une couche de signalisation, pour la création d'une liaison reçue par un client, déterminer s'il existe une liaison physique établie entre le client et un serveur ; et lorsqu'il y a la liaison physique établie, le client notifie le serveur à l'aide de la liaison physique établie, de sorte que le serveur forme une liaison de support selon la liaison physique établie. L'invention concerne en outre un autre procédé et un appareil permettant de mettre en oeuvre un traitement de connexion de liaison et un support de stockage informatique associé.
