Abstract

La présente invention concerne un procédé, une station de base, un équipement utilisateur et un point d'accès de fidélité sans fil, destinés à la gestion de ressources sans fil. Le procédé comprend : en tant que partie composante d'un réseau cellulaire, un premier dispositif réseau reçoit un premier message, le premier message étant utilisé pour refléter le statut du canal sans fil d'un premier point d'accès (AP) de fidélité sans fil (WiFi) ; sur la base du premier message, le premier dispositif réseau réalise une détermination de gestion de connexion sans fil sur un premier équipement utilisateur (UE) et le premier AP WiFi et obtient un résultat de la détermination de gestion de connexion sans fil ; le premier dispositif réseau envoie le résultat de la détermination de gestion de connexion sans fil au premier UE à des fins de signalement. Grâce à la présente invention, il est possible d'éviter que l'UE accède à un réseau WiFi surchargé ou à un réseau WiFi ayant une mauvaise qualité de canal, afin d'améliorer l'expérience de l'utilisateur.
