Abstract:
1. A mobile communication terminal for performing voice communication and data communication, comprising: a display means for displaying an operation state; a manipulation means for receiving input from the user and which has a power key for operating power-off; a communication means for performing voice communication and data communication; a positional information acquisition means for acquiring positional information indicating current location; a power control means for turning off power supplied to at least the display means and the manipulation means when a power-off operation is performed by the power key of the manipulation means; a control means for transmitting positional information acquired by the positional information acquisition means to another terminal or a monitoring unit via a network by the communication means after the supplied power has been turned off by the power control means; and a storage means for storing location positioning duration time information prescribing an amount of time the positional information is acquired and location positioning timing information prescribing the timing for acquiring the positional information; wherein said control means (i) activates said communication means, enters an idle state at a predetermined timing interval during a predetermined duration of time, and reads the location positioning duration time information and the location positioning timing information from the storage means after the supplied power has been turned off by said power control means, (ii) performs the positional information acquisition from said positional information acquisition means when a location positioning request message is received from said other terminal or said monitoring unit during the timing indicated by the location positioning timing information until a location positioning time duration indicated by the location positioning duration time information is reached, and (iii) transmits the acquired positional information to the other terminal or the monitoring unit via the network by said communication means; and wherein said power control means turns off the power supplied to the communication means after lapse of the predetermined duration of time.
