Abstract

Dans ses modes de réalisation, la présente invention se rapporte à un procédé et à un dispositif de contrôle de règles. Le procédé selon l'invention consiste : à être informé du fait qu'un équipement d'utilisateur (UE, User Equipment) entre dans un état d'attente au niveau d'un eNodeB domestique (HeNB, Home eNodeB) ; en se basant sur le fait que l'UE entre dans un état d'attente au niveau du HeNB, à transmettre une indication d'invalidation de données de tunnel à une fonction de règles de stratégie et de contrôle (PCRF, Policy Control and Rules Function) de telle sorte que la PCRF prenne une décision de stratégie et de contrôle sur la base de l'indication d'invalidation de données de tunnel, ladite indication d'invalidation de données de tunnel étant utilisée pour informer la PCRF que les données de tunnel entre le HeNB et une passerelle de sécurité ne sont pas valides. Dans les modes de réalisation de la présente invention, quand l'UE entre dans un état d'attente, la PCRF est informée, par l'indication d'invalidation de données de tunnel, que les données de tunnel entre le HeNB et la passerelle de sécurité ne sont pas valides. Par voie de conséquence, des ressources correspondantes sont libérées et l'efficacité d'utilisation des ressources du système est accrue.
