1. A method of handling a communication session, comprising:

  • at a wireless mobile communications device;

    receiving an indication of current signal strength of an access point for a wireless local area network (“

    WLAN”

    );

    retrieving a signal strength threshold associated with said access point;

    if said communication session is currently carried by a cellular network and said current signal strength exceeds said signal strength threshold, attempting to switch said communication session from said cellular network to said WLAN;

    if said attempting to switch fails, adjusting a failure rate associated with said access point and selectively decreasing said signal strength threshold if said failure rate is below a minimum threshold for said failure rate;

    wherein said failure rate is based on an average switch failure rate, at said wireless mobile communications device, from said cellular network to said access point of said WLAN within a predefined time window.
