Abstract
L'invention concerne un procédé et un dispositif de mise en œuvre de transfert intercellulaire dans un système de réseau mobile, et support de stockage. Par exemple, lorsqu'il est déterminé qu'un UE doit effectuer un transfert intercellulaire d'un réseau central d'un premier réseau central à un second réseau central sans changer l'emplacement physique d'une station de base, un RAN peut envoyer un message de requête de transfert intercellulaire à un dispositif de gestion, le message de requête de transfert transportant des informations d'instruction de transfert intercellulaire, de telle sorte que le dispositif de gestion achève le transfert intercellulaire et similaire conformément aux informations d'instruction de transfert intercellulaire. L'application de la solution de la présente invention permet de s'assurer que, lorsqu'un UE doit effectuer un transfert intercellulaire d'un réseau central d'un premier réseau central vers un second réseau central sans changer l'emplacement physique d'une station de base, le transfert intercellulaire est effectué sans à-coups.
