Abstract

L'invention, dans des modes de réalisation, concerne un procédé, un dispositif de réseau et un équipement utilisateur pour sélectionner une passerelle d'accès non-3GPP (3rd-Generation-Partnership-Project). Ledit procédé consiste en ce que le côté réseau détermine des informations de passerelle d'accès non-3GPP selon les informations d'emplacement de l'équipement utilisateur (UE), et la correspondance, auto-configurée ou configurée, sur le serveur de système des noms de domaines (DNS), entre les informations d'emplacement de l'UE et les informations de passerelle d'accès non-3GPP ; et le côté réseau transmet lesdites informations de passerelle d'accès non-3GPP à l'UE. L'invention concerne la sélection d'une passerelle d'accès non-3GPP dans un scénario de déploiement à grande échelle pour des réseaux d'accès non-3GPP.
