Abstract

L'invention concerne un procédé, un dispositif, une passerelle et un système d'attribution d'adresse IP. Le procédé comprend les étapes suivantes : une passerelle de desserte de données par paquets à haut débit (HSGW) acquiert une adresse IP d'une entité fonctionnelle de commande de paquets évoluée (ePCF) à laquelle un équipement d'utilisateur appartient ; la HSGW lie un message PBU mis à jour via un proxy et transmet une adresse IP de l'ePCF à une passerelle de réseau de données par paquets (PGW) ; la HSGW acquiert l'adresse IP de l'équipement d'utilisateur, de la PGW, et la transmet à l'équipement d'utilisateur ; l'adresse IP de l'équipement d'utilisateur est attribuée, par la PGW, à l'équipement d'utilisateur, d'après l'adresse IP de l'ePCF.
