Abstract
To handle a communication session at a wireless mobile communications device, after receiving an indication of current signal strength of an access point for a wireless local area network ('WLAN') a signal strength threshold associated with the access point is retrieved. If the communication session is currently carried by a cellular network and the current signal strength exceeds the signal strength threshold, the communication session is switched from the cellular network to the WLAN. A metric is then adjusted based on timing of the switch relative to any switch of the communication session from the WLAN to the cellular network over a preceding time window associated with the access point. Based on the metric, the signal strength threshold associated with the access point is selectively adjusted.
