A system for providing position information of a target mobile communication terminal whose position is to be found out. The system comprises a first mobile communication terminal and a second mobile communication terminal. The system further comprises a mobile communication server for generating AASA information using radio waves, transmitting the generated AASA information to the first mobile communication terminal and second mobile communication terminal upon receiving a position tracking signal transmitted from the first mobile communication terminal, and transferring second individual position information transmitted from the second mobile communication terminal to the first mobile communication terminal. The first mobile communication terminal calculates correlative position information between it and the second mobile communication terminal on the basis of the first individual position information and second individual position information at intervals of a predetermined time and outputs the calculated correlative position information to a screen.
