Abstract
A position information providing system of the invention, portable telephones A and B are connectable to a service center. The telephone A has a GPS processing circuit for measuring its own position and a control circuit. The circuit prepares position information based on the measurements obtained by the GPS processing circuit, also prepares a list comprising the numbers of a plurality of telephones in response to an input manipulation by the user, and transmits the prepared list data to the center. When an information request signal is supplied from the telephone B to the center, the server transmits the position information as to the telephone A to the telephone B only when the number of the telephone B is not included in the list data. Thus, the system realized is adapted to reliably protect the privacy of the person carrying the telephone A.
