Abstract

Un mode de réalisation de la présente invention concerne un procédé et un dispositif de détection du résultat de repli d'un repli par commutation de circuits (CSFB), et un support de stockage informatique. Le procédé consiste à : détecter, lors de l'initiation d'un CSFB sur la base d'informations de commande qui commandent à un terminal d'utiliser une solution d'optimisation CSFB prédéfinie pour exécuter un service vocal, si le terminal accède à une première cellule d'un système mondial de communications mobiles (GSM) dans une période de temps prédéfinie; commander le terminal qui accède à la première cellule GSM lorsque le terminal ne parvient pas à initier une procédure CSFB sur la base d'informations de configuration d'une seconde cellule GSM; envoyer des informations de point de fréquence de la seconde cellule GSM dans une instruction de redirection envoyée par une station de base LTE, les informations de configuration comprenant la configuration de deux canaux physiques pour un canal de commande commun; utiliser le résultat de détection pour déterminer si le repli CSFB a réussi, les informations de commande étant contenues dans un message d'acceptation de rattachement envoyé par la station de base LTE au terminal; et envoyer le message d'acceptation de rattachement, par la station de base LTE après que le terminal a envoyé un message de demande de rattachement à la station de base LTE.
