A method in a mobile communication device adapted to operate in a wireless area network, WWAN, and a wireless local area network, WLAN, the method comprising: operating for communications via the WLAN with use of a WWAN transceiver portion; performing one or more scanning operations with use of a WWAN transceiver portion for identifying a set of cell 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 identifications in association with a WLAN profile of the WLAN; while operating for communications with use of the WWAN transceiver portion: maintaining the WLAN transceiver portion in a low power state comprising setting of a substantially reduced scan rate of the WLAN transceiver portion; performing one or more scanning operations with use of the WWAN transceiver portion for identifying a current set of cell identifications, the current set of cell identifications corresponding to a serving base station of the mobile communication device and one or more neighboring base stations of the mobile communication device; comparing cell identifications of the current set with cell identifications of the stored set; and when the number or percentage of matching cell identifications of the current and stored sets meets or exceeds a predetermined threshold, exiting the WLAN transceiver portion from the low power state and enabling operation of the WLAN transceiver portion for identifying the WLAN for communications via the WLAN. operating for communications via the WLAN with use of a WWAN transceiver portion; performing one or more scanning operations with use of a WWAN transceiver portion for identifying a set of cell 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 identifications in association with a WLAN profile of the WLAN; while operating for communications with use of the WWAN transceiver portion: maintaining the WLAN transceiver portion in a low power state comprising setting of a substantially reduced scan rate of the WLAN transceiver portion; performing one or more scanning operations with use of the WWAN transceiver portion for identifying a current set of cell identifications, the current set of cell identifications corresponding to a serving base station of the mobile communication device and one or more neighboring base stations of the mobile communication device; comparing cell identifications of the current set with cell identifications of the stored set; and when the number or percentage of matching cell identifications of the current and stored sets meets or exceeds a predetermined threshold, exiting the WLAN transceiver portion from the low power state and enabling operation of the WLAN transceiver portion for identifying the WLAN for communications via the WLAN. maintaining the WLAN transceiver portion in a low power state comprising setting of a substantially reduced scan rate of the WLAN transceiver portion; performing one or more scanning operations with use of the WWAN transceiver portion for identifying a current set of cell identifications, the current set of cell identifications corresponding to a serving base station of the mobile communication device and one or more neighboring base stations of the mobile communication device; comparing cell identifications of the current set with cell identifications of the stored set; and when the number or percentage of matching cell identifications of the current and stored sets meets or exceeds a predetermined threshold, exiting the WLAN transceiver portion from the low power state and enabling operation of the WLAN transceiver portion for identifying the WLAN for communications via the WLAN.
