Abstract

L'invention concerne un procédé d'utilisation de la commande de politique et de facturation du service de la fonction d'application, qui consiste notamment en ce que lorsque l'équipement utilisateur en itinérance dans le réseau visité demande à utiliser le service de la fonction d'application, selon les informations d'abonnement de l'équipement utilisateur, la capacité du réseau visité et la politique prédéterminée détermine s'il y a lieu ou non d'autoriser ledit équipement utilisateur à utiliser ledit service; et dans l'affirmative, établit la politique correspondante et la règle de facturation et met en oeuvre la commande de politique et de facturation; dans le cas contraire, elle rejette la demande dudit service de l'équipement utilisateur. L'invention concerne également un système utilisant la commande de politique et de facturation correspondante de façon à examiner intégralement la condition d'abonnement de l'équipement utilisateur et la capacité réelle du réseau visité de déterminer s'il y a lieu ou non d'autoriser l'équipement utilisateur à accéder au service de la fonction d'application et de mettre en oeuvre exactement la commande de politique et de facturation du service lorsque l'équipement utilisateur en itinérance dans le réseau visité accède au service de la fonction d'application.
