Abstract

L'invention concerne un procédé et un système pour traiter des informations de localisation. Une passerelle résidentielle (RG), servant de client 802.1x, lance une requête d'authentification (510). Un nœud d'accès (AN), servant de dispositif d'authentification 802.1x et de client RADIUS (Remote Authentication Dial In User Service - service d'authentification distante des utilisateurs entrants), insère les informations de localisation de la RG dans la demande d'authentification reçue et envoie la demande d'authentification à un serveur d'authentification, autorisation et comptabilisation (AAA) (520) auquel on se référera pour les authentifications ultérieures. Au moyen de la technologie de traitement d'informations de localisation de la présente invention, un équipement d'utilisateur dont les informations de localisation ont réussi l'authentification n'a pas besoin d'être à nouveau authentifié lors d'un traitement de communication ultérieur, ce qui évite de répéter l'authentification de l'équipement d'utilisateur et simplifie le processus de communication. De plus, étant donné que les informations de localisation d'une RG sont associées au moment où a lieu l'authentification, la sécurité de l'authentification s'en trouve encore renforcée, ce qui permet de résoudre encore mieux les problèmes tels que ceux des accès illégaux.
