Abstract

L'invention concerne un procédé de commande de facturation de politique, un convertisseur de protocole, et un appareil de règle de facturation de politique. Le procédé comprend les étapes suivantes : un PC reçoit un message BTA transmis par une PCRF, le message BTA portant des politiques de prise de décision de transmission; après la réalisation d'une conversion de protocole sur le message BTA, la transmission d'un message de réponse de politique de transmission à une SCEF, le message de réponse de politique de transmission portant un identifiant de la PCRF; à recevoir un message de notification de politique de transmission transmis par la SCEF, le message de notification de politique de transmission portant l'identifiant de la PCRF et une politique de transmission sélectionnée parmi les politiques de transmission; et la transmission, à la PCRF, du message de notification de politique de transmission après la conversion de protocole.
