Abstract

L'invention concerne un procédé de contrôle d'accès et un appareil, le procédé consistant : à obtenir une valeur d'indicateur de puissance de signal reçue (RSSI) envoyée par un équipement utilisateur (UE) et des informations d'identification envoyées périodiquement par l'UE et utilisées pour identifier l'UE ; à déterminer, selon la valeur de RSSI, une distance entre l'UE et un dispositif monté dans un véhicule s'il est déterminé, selon les informations d'identification, que l'UE est connecté au dispositif monté dans un véhicule ; et à contrôler un accès à un réseau de l'UE selon la distance déterminée. L'invention résout un problème dans l'état de la technique associé dans lequel chaque équipement utilisateur ne peut pas être contrôlé séparément lorsque l'équipement utilisateur accède à un réseau, et obtient un contrôle séparé sur un équipement utilisateur individuel lorsque l'équipement utilisateur accède à un réseau, améliorant l'expérience d'utilisateur.
