Abstract

La présente invention concerne un procédé et un dispositif de commande d'état de connexion RRC entre un UE et un côté réseau. Lorsqu'une relation de connexion entre l'UE et le côté réseau existe, si l'UE détermine, en fonction d'un paramètre de fonctionnement de l'UE, qu'un service de données devant être exécuté n'existe pas dans un laps de temps correspondant aux informations de durée d'un mode CDRX distribué par le côté réseau, l'UE déconnecte la connexion RRC entre l'UE et le côté réseau. Au moyen de la solution technique de la présente invention, lorsque le temps du service de données devant être exécuté n'existe pas dans la durée du mode CDRX distribué par le côté réseau, l'UE requiert uniquement une simple interaction de signalisation avec le côté réseau, à savoir, l'UE peut être commuté à partir du mode CDRX vers un mode DRX. Du fait que ni la surveillance PDCCH, ni l'interaction de signalisation avec le côté réseau ne sont nécessaires lorsque l'UE se trouve en mode DRX, l'hypothèse de puissance de l'UE est réduite de manière efficace, et l'interaction de signalisation entre l'UE et le côté réseau est réduite, et les performances de réseau sont améliorées.
