Abstract

La présente invention concerne un procédé et un dispositif de transmission de données. Ledit procédé comprend les étapes au cours desquelles : en fonction d'informations d'authentification d'un équipement utilisateur, une passerelle de réseau local (LGW) attribue une adresse IP à l'équipement utilisateur et mémorise la corrélation de l'adresse IP, les réseaux locaux auxquels ladite adresse IP peut accéder et la qualité de service lorsqu'elle accède auxdits réseaux locaux ; et, en fonction de ladite qualité de service, la LGW transmet des données entre l'équipement utilisateur et le réseau local correspondant à l'adresse IP dudit équipement utilisateur. La présente invention règle les problèmes, sans solution dans l'art antérieur, se posant lorsque différents utilisateurs accèdent à différents réseaux locaux et lorsque différents utilisateurs accèdent à différents réseaux locaux en fonction d'adresses IP attribuées.
