Abstract

La présente invention concerne un procédé de sélection de réseau mobile terrestre public visité (VPLMN). Selon l'invention, une passerelle de réseau de données en paquets (P-GW) d'un réseau domestique fait l'acquisition d'un identificateur de VPLMN (ID de VPLMN) à partir d'un serveur d'authentification, d'autorisation et de comptabilisation (AAA) ou d'un équipement d'utilisateur (UE) du réseau domestique (201); et la P-GW du réseau domestique envoie l'ID de VPLMN à une entité à fonction de règles de politique et de facturation de réseau domestique (H-PCRF), et la H-PCRF reçoit l'ID de VPLMN (202). L'invention concerne également un système de sélection d'un VPLMN et d'une P-GW. La solution selon la présente invention permet à une H-PCRF de connaître un VPLMN où se trouve un mandataire de serveur AAA d'un VPLMN sélectionné lorsqu'un UE accède à une authentification, de façon à obtenir la garantie du fait qu'une V-PCRF sélectionnée par la H-PCRF et qu'un mandataire AAA d'un VPLMN sélectionné par un serveur AAA de forum à large bande (BBF) se trouvent dans un seul et même VPLMN.
