1. A mobile communication terminal for communicating with base stations forming a communication network comprising:

  • means for collecting at least positioning information containing base station information of the base stations;

    means for sending the positioning information on the communication network as information required for calculating a terminal position;

    means for acquiring terminal position information calculated for the communication network based on the positioning information;

    means for checking whether uncertain information equivalent to a position calculation error contained in the terminal position information is within a predetermined threshold; and

    means for controlling an output of the terminal position information to a terminal user, the controlling means enabling and disabling the output of the terminal position information when the uncertain information is less than and more than the predetermined threshold, respectively, and causing the collecting means and the sending means to collect and send the positioning information again to the communication network for positioning calculation when the uncertain information is more than the predetermined threshold.
