Abstract

La présente invention concerne un appareil et un procédé de synchronisation d'informations d'enregistrement, ainsi qu'un dispositif et un support. Le procédé peut s'appliquer à un terminal et comprend les étapes suivantes : lorsqu'un terminal est commuté d'un premier système de communication à un second système de communication, envoyer un premier message de demande de mise à jour de zone de suivi à un dispositif de réseau du second système de communication, le premier message de demande de mise à jour de zone de suivi comprenant un premier GUTI du terminal dans le premier système de communication ; recevoir un message d'acceptation de mise à jour de zone de suivi en provenance du dispositif de réseau, le message d'acceptation de mise à jour de zone de suivi comprenant un second GUTI, qui est configuré pour le terminal ; et lorsqu'il est déterminé que l'envoi d'un message d'achèvement de mise à jour de zone de suivi échoue, déclencher un temporisateur défini pour démarrer une synchronisation jusqu'à l'expiration du temporisateur défini, puis envoyer un second message de demande de mise à jour de zone de suivi au dispositif de réseau, le second message de demande de mise à jour de zone de suivi comprenant le second GUTI. Le procédé est utilisé pour améliorer la possibilité d'une synchronisation d'informations d'enregistrement réussie dans un scénario de synchronisation d'informations d'enregistrement.
