Abstract: front page image
(EN)This disclosure provides a method and for determining WLAN channel in a base station which supports both WLAN access and cellular network access, and a first WLAN channel is allocated for its WLAN access. According to this disclosure, if frequency space between the first WLAN channel and frequency range occupied by the cellular network access is not larger than a threshold, the base station detects available WLAN channels which are not occupied by surrounding WLANs. If the frequency space between the available WLAN channels and the frequency range occupied by the cellular network is not larger than the threshold, the base station changes its WLAN channel from the first WLAN channel to a second WLAN channel occupied by one of the surrounding WLANs. The frequency space between the second WLAN channel and the frequency range occupied by the cellular network access is larger than the threshold, thus interference between the cellular network and the WLAN is reduced or eliminated. This disclosure also provides a base station.
(FR)L'invention concerne un procédé de détermination de canal WLAN dans une station de base prenant en charge un accès WLAN et un accès cellulaire, un premier canal WLAN étant alloué pour l'accès WLAN. Selon l'invention, si un intervalle de fréquence entre le premier canal WLAN et une plage de fréquences occupée par l'accès cellulaire ne dépasse pas un seuil, la station de base détecte des canaux WLAN disponibles qui ne sont pas occupés par des WLAN alentour. Si l'intervalle de fréquence entre les canaux WLAN disponibles et la plage de fréquences occupée par l'accès cellulaire ne dépasse pas le seuil, la station de base change son canal WLAN en passant du premier canal WLAN à un second canal WLAN occupé par l'un des WLAN alentour. Comme l'intervalle de fréquence entre le second canal WLAN et la plage de fréquences occupée par l'accès cellulaire dépasse le seuil, une interférence entre le réseau cellulaire et le WLAN est réduite, voire éliminée. L'invention concerne également une station de base.
