Abstract

Un procédé pour rapporter des informations concernant une anormalité de liaison comporte les étapes consistant à : détecter si une liaison entre un contrôleur de station de base (BSC) et une passerelle média (MGW) est normale ou non (s201); si l'anormalité apparaît dans la liaison (102), un message portant l'information concernant l'anormalité de la liaison est envoyé (s202) à un centre de commutation mobile (MSC). L'invention concerne également un contrôleur de station de base, une passerelle média et un réseau de système global de télécommunication mobile (GSM). Dans le réseau GSM de l'invention, lorsque l'anormalité survient dans la liaison entre le contrôleur de station de base et la passerelle média, le message portant l'information concernant l'anormalité de la liaison est envoyé au MSC par le BSC ou la MGW de sorte que le MSC arrête par conséquent d'assigner un processus; on évite ainsi qu'un côté de signalisation soit connecté mais qu'un côté utilisateur ne soit pas connecté.
