ABSTRACT:
A method of 2-way data and voice communication with a user utilizing a portable device having a cellular transceiver module, a GPS module and an emergency call button is disclosed. The method includes determining whether the portable device is in proximity of the base station; powering down the GPS, placing the portable device into sleep mode and sending a signal to the base station indicating that said portable device is in proximity of the base station when the portable device is in proximity to the base station; and activating and fully powering the cellular transceiver module and activating and fully powering said GPS module when the portable device is not in proximity of said base station. When not in proximity, the method also includes collecting an initial GPS location data from the GPS module and storing the location data into a memory location; placing the GPS module into a lower power mode and fully powering the GPS module, acquiring and storing additional GPS location data only at specified intervals to conserve battery life while monitoring the cellular transceiver module for inquiries and monitoring the emergency call button for an emergency signal. Various other steps occur when the emergency button is depressed.
