A method in a mobile communication device adapted to operate in a wireless wide area network "WWAN" and a wireless local area network "WLAN", the method comprising the acts of: providing operation for communications via the WLAN with use of a WLAN transceiver portion; performing one or more scanning operations with use of a WWAN transceiver portion for identifying a set of cell site identifications corresponding to a plurality of base stations of one or more WWANs available in a coverage region of the WLAN; storing the set of cell site identifications in association with a WLAN profile of the WLAN; while traversing the coverage region of the WLAN, regularly updating the stored set of cell site identifications with additionally-received cell site identifications that do not already exist in the stored set, as the base stations that are available in the coverage region of the WLAN change depending on which area of the coverage region the mobile communication device is located; while operating for communications via a WWAN with use of the WWAN transceiver portion: performing one or more scanning operations with use of the WWAN transceiver portion for identifying a current set of cell site identifications, the current set of cell site identifications corresponding to a serving base station of the WWAN and one or more neighboring base stations of the mobile communication device; comparing cell site identifications of the current set with cell site identifications of the stored set; if, based on the comparison, it is identified that the percentage of matching cell site identifications of the current and stored sets meets or exceeds a predetermined threshold which is set to be less than 100%, indicating that the WLAN has an increased probability of being found, then enabling operation of the WLAN transceiver portion for communications via the WLAN; and otherwise, if it is identified that the percentage of matching cell site identifications of the current and stored sets fails to meet or exceed the predetermined threshold which is set to be less than 100%, then refraining from enabling operation of the WLAN transceiver portion for communications via the WLAN. providing operation for communications via the WLAN with use of a WLAN transceiver portion;
