Abstract

L'invention concerne un procédé pour accéder à un sous-réseau qui consiste : à faire déterminer, par un dispositif de sélection de sous-réseau, qu'un accès à un sous-réseau doit être déclenché pour une unité d'UE ; à déclencher un accès à un sous-réseau pour l'unité d'UE. Dans un autre mode de réalisation, l'invention concerne un procédé pour accéder à un sous-réseau qui consiste : à faire déterminer, par une unité d'équipement utilisateur (UE), une requête d'accès comprenant des informations d'identificateur d'UE et/ou des informations pertinentes de service ; à transmettre la requête d'accès à un dispositif de sélection de sous-réseau, de telle sorte que le dispositif de sélection de sous-réseau demande, pour l'unité d'UE, des informations associées à un premier sous-réseau devant faire l'objet d'un accès et déclenche un accès à un sous-réseau pour l'unité d'UE. L'invention concerne également un dispositif associé et un support de stockage lisible par ordinateur.
