Abstract

Le mode de réalisation de la présente invention concerne un procédé, un système et un équipement de rapport d'un résultat de mise en œuvre de politique. Un nœud d'accès (AN) exécute la politique pour un service, conformément aux informations de politique correspondant au service, et envoie le message de rapport comprenant un résultat de mise en œuvre de politique à une passerelle de réseau à large bande (BNG). La BNG peut ensuite recevoir un résultat de mise en œuvre de politique et rapidement optimiser la capacité du réseau. En outre, lorsque la mise en œuvre de politique obtient un résultat d'échec, le messagede rapport peut comprendre la raison pour la simultanéité du résultat d'échec ; la BNG peut analyser la raison et ajuster la capacité du système. La BNG peut aussi construire une communication des couches d'application avec un équipement des locaux d'abonnés (CPE) conformément au serveur d'application, puis envoyer un résultat de mise en œuvre de politique et la raison d'échec au CPE et amener l'utilisateur à connaître le résultat de mise en œuvre de politique et à ajuster l'opération dans le temps conformément à l'échec provoqué par sa propre mauvaise opération.
