Automatic channel selection in a radio access network
First Claim
1. A method for selecting a radio frequency channel from among a plurality of available channels for use by an access point in a radio access network, comprising the steps of:
- (a) randomly choosing a channel from the plurality of channels;
(b) monitoring the chosen channel for a random interval to determine if the chosen channel is presently carrying traffic; and
(c) claiming the channel for carrying traffic by the access point unless the chosen channel is presently carrying traffic.

Abstract
Within a radio access network (111, 112) an access point (181, 182, 183 and 184) selects a channel by first randomly choosing a channel from those available for use. The Access Point then monitors the channel for a random interval to determine if the channel is presently carrying traffic. The Access Point will select the channel unless the channel is in use by another AP. If so, then the AP will select another channel and commence monitoring for a random interval in order to determine whether the channel is available. The AP will continue to choose channels until a suitable channel is found, or all available channels have been exhausted.

7. A method for selecting a radio frequency channel from among a plurality of available channels for use by an access point in a radio access network, comprising the steps of:
-
(a) determining whether a last used channel is available for use and claiming that channel for use, but if the last used channel is not available, then (b) randomly choosing a channel from among the plurality of available channels;
(c) monitoring the chosen channel for a random interval to determine if the chosen channel is presently carrying traffic; and
(d) claiming the channel for carrying traffic by the access point unless the chosen channel is presently carrying traffic. - View Dependent Claims (8, 9, 10, 11, 12)
