Patent ID: 7454214

Claim:
A method of selecting at least an optimal channel for use by an access point (AP) having at least an operating channel, the method comprising: determining a plurality of candidate channels for use by the AP; selecting from the plurality of candidate channels a channel used for a new operation channel by performing the following optimization channel selection process: computing predicted channel utilization for all of the candidate channels; selecting from the plurality of candidate channels a channel with the lowest channel utilization; determining if the selected channel with the lowest channel utilization is different from a current operating channel; determining whether the channel utilization of the current operating channel is greater than the channel utilization of the selected channel with the lowest channel utilization by at least a predefined threshold, if the selected channel with the lowest channel utilization is different from the current operating channel; and ending the optimization channel selection process if the selected channel with the lowest channel utilization is the same as the current operating channel, or if the channel utilization of the current operating channel is not greater than the channel utilization of the selected channel with the lowest channel utilization by at least a predefined threshold; determining whether there are any wireless transmit/receive units (WTRUs) associated with the AP through the current operating channel, if the channel utilization of the current operating channel is greater than the channel utilization of the selected channel with the lowest channel utilization by at least a predefined threshold; and disassociating all of the associated WTRUs.
