First Claim
1. A tracking method comprising the steps of:
- (A) establishing in a mobile terminal a landmark database that contains location data of a plurality of predetermined landmarks;
(B) enabling the mobile terminal to periodically receive a position information signal that contains position information of the mobile terminal; and
(C) enabling the mobile terminal to generate a location information signal that is subsequently transmitted to a locating party through a wireless telecommunications network, the location information signal being generated with reference to the landmark database and the position information of the position information signal received in step (B), and indicating one of the landmarks in the landmark database that is closest to the mobile terminal.
