Abstract

Un mode de réalisation de la présente invention concerne un procédé et un dispositif pour détecter le résultat de repli d'un repli à commutation de circuits (CSFB), et un support de stockage informatique, le procédé comprenant : lors de l'initiation d'un CSFB sur la base d'informations d'instruction ordonnant à un terminal d'effectuer un service vocal au moyen d'une solution d'optimisation de CSFB prédéfinie, détection si un terminal accède à une première cellule du système mondial de communications mobiles (GSM) au sein d'une période prédéfinie, le terminal accédant à la première cellule GSM étant déclenché sans réponse lorsque le terminal initie une procédure de CSFB de façon à accéder à une deuxième cellule GSM, et des deuxièmes informations de point de fréquence de cellule GSM sont transportées dans une instruction de redirection qui est envoyée par une station de base LTE ; en utilisant le résultat de la détection, détermination si un repli du CSFB est réussi. Les informations d'instruction sont transportées dans un message d'acceptation de rattachement qui est envoyé au terminal par la station de base LTE, et le message d'acceptation de rattachement est envoyé par la station de base LTE après que le terminal envoie un message de demande de rattachement à la station de base LTE. Le processus de CSFB est déclenché et exécuté lorsque le terminal reçoit un message de radiomessagerie qui est envoyé par la station de base LTE.
