Abstract

L'invention concerne un procédé d'information d'un utilisateur de l'échec d'un appel. Après l'envoi d'une demande d'appel par un utilisateur mobile, et avant l'établissement d'un canal vocal, lorsqu'un appel échoue et qu'aucun rappel provenant de l'utilisateur mobile est reçu dans un temps prédéterminé dans le centre de commutation mobile (MSC), ledit MSC envoie un message d'erreur à l'utilisateur mobile. L'invention concerne également un dispositif et un MSC pour informer l'utilisateur de l'échec d'un appel. La mise en oeuvre de l'invention, lorsque l'utilisateur mobile est l'appelant, et dans le cas où le canal vocal n'est pas établit, permet au côté réseau d'envoyer un message d'erreur à l'utilisateur au moyen de mots, de sons vocaux, de mots et de sons vocaux, etc., ce qui rend le système plus convivial.
