Abstract

La présente divulgation appartient au domaine technique des communications. La présente divulgation concerne des procédés et des appareils de commande de communication et un support de stockage. Un procédé comprend l'étape suivante : un terminal envoie des premières informations à un dispositif de réseau, les premières informations étant utilisées pour déterminer le nombre de filtres de paquets, le nombre de filtres de paquets étant appliqué à une règle de qualité de service dérivée (QoS dérivée), et les filtres de paquets étant utilisés pour filtrer des paquets de données. La solution de la présente divulgation permet au dispositif de réseau d'obtenir le nombre de filtres de paquets pris en charge par la règle de QoS dérivée, de sorte que le dispositif de réseau n'utilise pas la QoS réfléchissante du nombre de filtres de paquets qui n'est pas pris en charge par le terminal, ce qui permet de résoudre le problème selon lequel la QoS réfléchissante des terminaux ne peut pas être complètement prise en charge.
