Abstract

La présente invention concerne un procédé et un système de commande de politique et un dispositif de commande de politique. Selon le procédé, un dispositif de commande de politique reçoit un message (101) de demande de ressources, puis il détermine, en fonction du seuil enregistré d'un quota de ressources, si la valeur de toutes les ressources autorisées après la réception de la demande de ressource est supérieure au seuil du quota (102) de ressources; si la valeur de toutes les ressources autorisées est supérieure audit seuil, alors le dispositif de commande de politique applique un nouveau quota de ressources à un réseau de transmission, puis il actualise le seuil du quota de ressources d'après un résultat d'attribution reçu pour le quota (103) de ressources. L'utilisation de ce procédé, du système et du dispositif de commande de politique selon l'invention, permet de solutionner le problème de surcharge de la signalisation d'une commande de politique dans le cas où la charge de la station de base domestique évoluée ou lorsque le service d'un équipement utilisateur (UE) change relativement fréquemment, ce qui garantit une meilleure expérience pour l'utilisateur.
