摘要:
A method for locating a mobile communication device includes the steps of sensing geocoordinates that represent the telephone's approximate location, comparing the sensed geocoordinates to predefined geocoordinates that represent a home location municipal address, selecting geocoordinates responsive to the comparison, and locating the portable telephone according to the selected geocoordinates. In another embodiment, a cellular telephone includes a positioning receiver for sensing approximate geocoordinates of the cellular telephone, memory for storing home-location geocoordinates, logic for comparing the approximate geocoordinates with the home-location geocoordinates and for selecting a preferred position responsive to the outcome of the comparison; and a radio transmitter for transmitting the preferred position to a public safety answering point.
