Abstract

La présente invention concerne un procédé de gestion de compte lors d'une interaction de réseau local sans fil (WLAN)/réseau fixe, faisant appel : à l'envoi, par un contrôleur d'accès (AC), d'un message de notification d'utilisateur en ligne à une passerelle de réseau à large bande (BNG) après le rattachement au réseau réalisé avec succès d'un équipement d'utilisateur (UE); à l'envoi simultané, par l'AC, d'un message de requête de gestion de compte à un serveur d'authentification, d'autorisation et de gestion de compte (AAA); et à l'exécution, par le serveur AAA, de la gestion de compte de l'UE après la réception du message de requête de gestion de compte. L'invention concerne également un système de gestion de compte lors d'une interaction de WLAN/réseau fixe et un procédé ainsi qu'un système d'attribution d'adresse d'utilisateur lors d'une interaction de WLAN/réseau fixe. En adoptant la présente invention, l'accès au réseau de l'UE peut être efficacement commandé sous l'architecture d'interaction de WLAN/réseau fixe.
