ABSTRACT:
A mobile communication terminal stores positioning information including global positioning system signals and base station information required by a position server in a communication network to calculate the terminal position. When the position server calculates the terminal position based on these positioning unit information, the position information is not reported to the user if the indefinite information equivalent to a positioning error contained in the average value calculated for the terminal position information exceeds a predetermined threshold value. When the average processing count exceeds a maximum positioning count, that average value is reported to the user.
