ABSTRACT:
A wireless device capable of wireless local area network (WLAN) communications and cellular network communications stores profiles of wireless local area networks. The device identifies in which cell of a cellular network the device is currently located, and then scans more frequently for wireless local area networks matching profiles to which, previously, the device has connected while located in the cell, than for wireless local area networks matching other profiles.
