Abstract

L'invention concerne un procédé de détection d'un réseau local sans fil, d'un dispositif de réseau d'accès, d'un dispositif de réseau central et d'un point d'accès. Le procédé consiste : à recevoir d'un UE un message de mesure de cellule voisine ; si le message de mesure de cellule voisine porte des informations concernant une cellule virtuelle, à envoyer un message de notification vers un dispositif de réseau central, le message de notification étant utilisé pour indiquer à l'UE d'accéder à une zone de couverture d'un WLAN, afin de permettre au dispositif de réseau central de notifier l'UE que l'UE accède à la zone de couverture du WLAN, la cellule virtuelle étant générée par un point d'accès du WLAN et la zone de couverture de la cellule virtuelle étant identique à celle du WLAN. Dans des modes de réalisation de la présente invention, si des informations concernant une cellule virtuelle générée par un AP sont contenues dans le message de mesure de cellule voisine d'un UE, un dispositif de réseau central est notifié qu'un UE accède à la zone de couverture d'un WLAN par l'intermédiaire d'un dispositif de réseau d'accès, le dispositif de réseau central notifie à l'UE d'accéder à la zone de couverture du WLAN sans que l'UE n'ait à découvrir la zone de couverture du WLAN par l'intermédiaire d'un logiciel client. La perception du WLAN par l'UE peut par conséquent être améliorée.
