Abstract
A mobile terminal position information display system which detects accurate information on a position between a radio controller and a radio telephone and displays the position and locus of movement of the radio telephone. The system includes one or more mobile terminals which make communication by radio to output signals indicative of their positions; one or more mobile terminal control units for transmitting/receiving a signal to/from a mobile terminal, at least one exchange to which a mobile terminal control unit is connected, and an output processor including an analyzer for analyzing the signal indicative of the position of the mobile terminal from the reporting unit to output information on the position of the mobile terminal. The mobile terminal control units each include a detector for detecting a signal indicative of the position of a mobile terminal. Each exchange includes a reporting unit for providing to the output processor a signal indicative of the position of the mobile terminal detected by the detector.
