Abstract
In a wireless terminal position measuring method for estimating the position of a terminal using signals sent from at least three base stations accommodated by a cellular communication system, position of the terminal is estimates according to the triangulation method by selecting three base stations arbitrarily, a plurality of estimated positions thus calculated are stored in a memory and averaged thereafter to obtain a final estimated position.
