Patent ID: 8731509

Claim:
A method in a mobile communication device configured to operate for communications over a communication channel of a wireless local area network (WLAN), the method comprising: receiving, at the mobile communication device, signals over the communication channel of the WLAN; sampling, at the mobile communication device at a rate R, a received signal strength indication (RSSI) of the signals received over the communication channel; obtaining at the mobile communication device a measurement M of velocity or acceleration of the mobile communication device; repeating the acts of receiving, sampling, and obtaining; in response to the measure M≦M 1 , setting the rate R=R 1 at the mobile communication device; in response to the measure M>M 1 , setting the rate R=R 2 at the mobile communication device, where R 2 >R 1 ; determining at the mobile communication device a signal quality estimate of the communication channel based on a plurality of samples received from the sampling of the RSSI at the rate R; and providing an indication to permit handover to a wireless wide area network (WWAN) based on the signal quality estimate.
