Abstract

L'invention concerne des procédés, des systèmes et des dispositifs destinés aux communications sans fil. Les techniques décrites prennent en charge l'authentification et l'autorisation (AA) pour divers services fournis par un réseau et pris en charge par un équipement utilisateur (UE). Un équipement utilisateur peut transmettre un conteneur à une première entité de réseau demandant une authentification et autorisation pour un premier service. Le conteneur peut comprendre un indicateur du premier service, et l'indicateur peut indiquer ou distinguer le premier service parmi une pluralité de services. La première entité de réseau peut interroger une troisième entité de réseau sur la base de l'indicateur du premier service pour découvrir une deuxième entité de réseau prenant en charge une authentification et autorisation pour le premier service. La première entité de réseau peut ensuite transmettre un indicateur du premier service à la deuxième entité de réseau, et la deuxième entité de réseau peut sélectionner une quatrième entité de réseau prenant en charge une authentification et autorisation pour le premier service.
