PROBLEM TO BE SOLVED: To allow a receiver side to recognize the moving position on a map of a monitor and to display the moving position from a remote place by incorporating into a mobile communication equipment, such as a beeper and a portable telephone set a radio wave transmission function to automatically inform the moving position through remote control. SOLUTION: An instruction signal is sent from a caller side of a monitor so as to activate a transmission switch to a communication equipment, such as a beeper and a portable telephone set incorporating a position transmission function for allowing the communication equipment to transmit a position signal. Then a receiver side receives the position signal sent from the communication equipment to confirm the moving position of the communication equipment on a map of the monitor, so as to recognize where a person carrying the mobile communication equipment is located. |
