Abstract

L'invention concerne un procédé, un dispositif et un système de communication VoLTE. Le procédé comporte les étapes consistant à: faire établir par un terminal une procédure de signalisation de protocole d'ouverture de session avec une station de base LTE, la station de base LTE étant une station de base LTE à laquelle le terminal accède actuellement; interdire au terminal d'envoyer un compte rendu de mesure à la station de base LTE; déterminer que le terminal obtient un support dédié ou passe en continuité d'appel vocal radio unique (SRVCC); et annuler l'interdiction faite au terminal d'envoyer le compte rendu de mesure à la station de base LTE. Le procédé peut éviter l'interruption d'une procédure de signalisation de protocole d'ouverture de session et ainsi un échec d'appel qui en résulte, causés par le fait qu'une station de base LTE fasse passer directement un terminal d'un réseau LTE à un réseau 2G/3G au moyen d'une redirection de cellule ou d'une commutation de cellule en raison du fait que le terminal signale un compte rendu de mesure pendant la procédure de signalisation de protocole d'ouverture de session.
