Abstract

L'invention concerne un procédé et un dispositif adaptés pour sélectionner un réseau d'accès. Le procédé comprend : l'obtention, par un dispositif de réseau d'accès, d'une politique d'accès à un service d'un équipement d'utilisateur (UE), la politique d'accès à un service étant obtenue sur la base d'une politique de sélection de réseau d'accès fournie pour l'UE par un module de fonction de recherche et de sélection de réseau d'accès (ANDSF) ; et la sélection du réseau d'accès pour le service de l'UE sur la base de la politique d'accès à un service. Dans la solution fournie dans les modes de réalisation de la présente invention, la politique d'accès à un service est générée pour l'UE sur la base de la politique de sélection de réseau d'accès fourni par le module ANDSF. L'UE peut accéder à un réseau sur la base de la politique d'accès à un service. Le procédé dynamique peut sélectionner le réseau d'accès le mieux adapté pour l'UE quand un système d'accès contrôlé par le dispositif de réseau d'accès est en conflit avec la politique fournie par l'ANDSF.
