Abstract

L'invention concerne un procédé, un dispositif et un système de traitement de nom de point d'accès (APN), le procédé comprenant : la transmission à un serveur d'authentification, d'autorisation et de comptabilité (AAA), par une passerelle de données paquets évoluée (ePDG), d'informations d'indication servant à indiquer le type d'adresse d'un équipement utilisateur (UE) ; la réception, par l'ePDG, du contexte APN de passage de contrat sélectionné par le serveur AAA conformément aux informations d'indication ; et, en fonction du contexte APN de passage de contrat sélectionné, l'exécution par l'ePDG d'une opération d'accès de l'UE à l'ePDG. La présente invention aborde le problème qui, selon les techniques connexes, oblige une ePDG à refuser l'accès d'un utilisateur lorsque l'UE ne porte pas d'APN et que le type de PDN porté ne correspond pas au type de PDN dans le contexte APN de passage de contrat par défaut, et elle permet donc d'améliorer l'expérience utilisateur.
