Abstract

La présente invention concerne un procédé, un dispositif et un équipement de terminal de commutation de réseau. Le procédé consiste : à détecter une puissance de signal de réseau correspondant à un identifiant de l'ensemble du service (SSID) faisant actuellement l'objet d'un accès ; si la puissance de signal de réseau est inférieure à un seuil de commutation prédéterminé, à trier les puissances de signal de réseau correspondant à d'autres SSID dont les utilisations sont autorisées pour acquérir le résultat trié ; et à commuter un réseau correspondant au SSID ayant fait actuellement l'objet d'un accès vers un réseau correspondant à un autre SSID dans le résultat trié selon le résultat trié. L'équipement de terminal, par utilisation de ce procédé de commutation de SSID intelligent, peut prévenir le problème selon lequel un signal d'un SSID auquel l'équipement de terminal est connecté s'affaiblit ou la connexion réseau est même interrompue lorsque la distance de la source de SSID connectée augmente au cours du déplacement de l'équipement de terminal en raison du fait que l'équipement de terminal peut se connecter automatiquement à un SSID ayant des signaux puissants, permettant ainsi d'offrir une meilleure expérience de réseau à l'utilisateur.
