Location positioning setting information is read from a setting storage section when the user depressed a power key. The location positioning setting information comprises setting information, such as the maximum duration time of the location positioning operation and the operation timing when a power-off event has been generated. A control section turns off the power of a display section, a speaker, a microphone, etc., excluding a communication function for transmitting location positioning and positioning results. In this state, a location positioning section acquires the positional information of the mobile communication terminal. Then, a wireless communication section transmits the location positioning information of the positioned mobile communication terminal to a predetermined monitoring server which manages the positional information of the mobile communication terminal.
