Method and device for determining WLAN channel
First Claim
1. A method for determining WLAN channel in a base station, wherein the base station supports both WLAN access and cellular network access, and a first WLAN channel is allocated for the base station'"'"'s WLAN access, the method comprising:
- detecting available WLAN channels that are not occupied by surrounding WLANs, in response to a determination that frequency space between the first WLAN channel and frequency range occupied by the cellular network access is not larger than a threshold;
changing WLAN channel of the base station from the first WLAN channel to a second WLAN channel occupied by one of the surrounding WLANs, in response to a determination that frequency space between each of the available WLAN channels and the frequency range occupied by the cellular network is not larger than the threshold, wherein frequency space between the second WLAN channel and the frequency range occupied by the cellular network access is larger than the threshold.

Abstract
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.

8. A base station supporting both WLAN access and cellular network access, and a first WLAN channel being allocated for its WLAN access, the base station comprising a processing circuit and a memory circuit, the memory circuit storing program instructions executable by the processing circuit and configured to cause the base station, when the program instructions are executed by the processing circuit, to:
-
detect available WLAN channels which are not occupied by surrounding WLANs, in response to a determination that frequency space between the first WLAN channel and frequency range occupied by the cellular network access is not larger than a threshold; and change WLAN channel of the base station from the first WLAN channel to a second WLAN channel occupied by one of the surrounding WLANs, in response to a determination that frequency space between each of the available WLAN channels and the frequency range occupied by the cellular network is not larger than the threshold, wherein frequency space between the second WLAN channel and the frequency range occupied by the cellular network access is larger than the threshold. - View Dependent Claims (9, 10, 11, 12, 13, 14)
