Abstract

La présente invention concerne un procédé de contrôle d'accès d'un équipement utilisateur (UE), une entité de gestion de mobilité et un équipement utilisateur. Dans la présente, le procédé de contrôle d'accès de l'UE comprend les étapes suivantes : une demande d'accès initiée par l'UE est reçue dans la zone limitée (S100) ; on juge si l'UE a terminé ou non un service d'urgence avant d'initier la requête d'accès, et si l'UE a terminé le service d'urgence, l'accès de l'UE est autorisé (S102). L'application du procédé fourni par les modes de réalisation de la présente invention permet à l'UE de pouvoir encore traiter le service d'urgence lorsque l'UE se trouve dans la zone limitée et qu'il a terminé le service urgence.
