Abstract

L'invention concerne un procédé et un appareil de contrôle d'accès d'un groupe à un réseau sans fil. Différents groupes d'informations de contrôle de politique de groupe sont sauvegardés dans un serveur d'abonnés résidentiel. Lorsqu'un équipement utilisateur figurant dans un groupe accède à un réseau sans fil, le serveur d'abonnés résidentiel fournit, à une entité de gestion de mobilité, des informations de contrôle de politique de groupe de l'équipement utilisateur. L'entité de gestion de mobilité répond à un message de requête d'accès d'un équipement utilisateur figurant dans le groupe conformément aux informations de contrôle de politique de groupe. En conséquence, un équipement utilisateur figurant dans un groupe est effectivement soumis à un contrôle d'accès à un réseau sans fil conformément à des exigences d'accès de différents groupes.
