Patent ID: 8509199

Claim:
A method of detecting a duplicate service set identifier in a wireless local area network, the method comprising: generating a probe request packet by inserting a service set identifier of a service access point in the probe request packet in response to a scan request; transmitting the probe request packet to neighbor access points; receiving probe response packets; detecting service set identifiers included in the probe response packets; determining, by the service access point, a presence of a neighbor access point having a service set identifier that is the same as the service set identifier of the service access point in response to at least one of the detected service set identifiers of at least one of the neighbor access points being the same as the service set identifier of the service access point; receiving beacons transmitted from the neighbor access points; scanning the neighbor access points to acquire information of the neighbor access points; detecting service set identifier fields of the received beacons; determining whether any of the detected service set identifiers of the beacons is the same as the service set identifier of the service access point; and transmitting a result of the determining to a user.
