A portable communication device () is provided with first transceiver circuitry () for sending and receiving signals on a first communication path and second transceiver circuitry () for sending and receiving signals on a second communication path. The portable communication device () also includes a controller () coupled to the first transceiver circuitry () and the second transceiver circuitry () for providing a deregistration message to the second transceiver circuitry () for transmission therefrom in response to determining that the portable communication device () is within signal coverage of the first communication path, activating the first transceiver circuitry () to send and receive signals on the first communication path, deactivating the second transceiver circuitry (), and thereafter activating the second transceiver circuitry () at times separated by a predetermined time interval to monitor at least one housekeeping channel of the second communication path.
