Abstract

L'invention concerne un procédé, un dispositif et un système de contrôle de politique pour un utilisateur, se rapportant au domaine des communications. Dans l'invention, lorsqu'un utilisateur réalise un accès, un enregistreur de localisation nominal (HLR) est appliqué pour évaluer si un PCRF domestique est nécessaire pour réaliser un contrôle de politique sur l'utilisateur, lorsqu'un contrôle de politique ne peut pas être réalisé sur l'utilisateur tant qu'un PCRF domestique correspondant à l'utilisateur est appliqué, un PCRF domestique qui peut réaliser un contrôle de politique pour un service spécial auquel l'utilisateur s'abonne est recherché et déterminé, ce qui diminue la complexité de réseau et rend possible de satisfaire aux demandes de synchronisation de données dans un scénario de déploiement de PCRF multiples.
