Abstract

La présente invention concerne un procédé et un dispositif pour la transmission et l'ordonnancement de paquets de données. Le procédé de transmission comprend les étapes suivantes : un dispositif passerelle de réseau mobile obtient, en fonction d'informations de bande passante garantie correspondant à un flux de service, un premier paquet de données et un deuxième paquet de données du flux de service, le premier paquet de données ne dépassant pas la bande passante identifiée par les informations de bande passante garantie et le deuxième paquet de données dépassant la bande passante identifiée par les informations de bande passante garantie; le dispositif passerelle de réseau mobile marque le premier paquet de données et/ou le deuxième paquet de données; le dispositif passerelle de réseau mobile transmet le premier paquet de données et le deuxième paquet de données à un dispositif passerelle de réseau fixe de sorte que ce dernier procède à l'ordonnancement du premier paquet de données lorsque le réseau est encombré, en fonction de la marque du premier paquet de données et/ou de la marque du deuxième paquet de données. L'invention permet ainsi que la bande passante du flux de service ne soit pas inférieure à celle identifiée par les informations de bande passante garantie, correspondant au flux de service, et assure ainsi le fonctionnement normal du service correspondant au flux de service.
