Abstract

La présente invention concerne un procédé, un système et un appareil de génération d'une règle de politique. Dans le procédé : si des informations de description de flux de réseau privé mappées par un convertisseur de protocole (PC) ou une fonction de commande d'accès d'application (AAC) d'après des informations de description de flux de réseau public dans deux éléments ou plus d'informations de description de service de réseau public fournies par un réseau privé sont identiques, le PC ou l'AAC fournissent des informations de description de service de réseau privé à une PCRF, les informations de description de flux de réseau privé et des informations de bande passante de demande cumulées sont acheminées, et les informations de bande passante de demande cumulées sont générées d'après des informations de bande passante de demande dans les deux éléments ou plus d'informations de description de service de réseau public ; et, d'après les informations de description de flux de réseau privé et les informations de bande passante de demande cumulées, la PCRF génère une règle PCC. L'invention résout le problème lié au fait qu'une réservation et un contrôle de ressources d'un terminal d'utilisateur pour une pluralité d'accès de service initiée simultanément pour un service sont incorrects. L'invention permet ainsi d'exécuter une réservation et un contrôle de ressources d'un terminal d'utilisateur pour une pluralité d'accès de service initiée simultanément pour un service.
