Abstract

L'invention concerne un procédé et un dispositif d'établissement d'une connexion WLAN entre un équipement utilisateur et un point d'accès Wi-FI, qui permettent qu'une station de base se substitue à un UE pour réaliser un processus d'authentification d'un point d'accès Wi-Fi, évitant le retard d'accès et, en même temps, que la station de base puisse également commander l'UE pour qu'il sélectionne un point d'accès Wi-Fi approprié pour l'accès, améliorant la qualité de service.
