<p><P>PROBLEM TO BE SOLVED: To provide a mobile communication terminal device capable of appropriately reducing power consumption. <P>SOLUTION: A mobile communication terminal device comprises: a baseband processing part 3; a power supply means 11 for supplying power to the baseband processing part 3; and an out-of-radius detection means 4 for detecting whether or not a mobile communication terminal device 100 is out of the radius. A power supply control means 10 is provided for controlling the on/off of power supply from the power supply means 11 to the baseband processing part 3. If the duration of a state that an out-of-radius is detected by the out-of-radius detection means 4 becomes equal with or longer than a predetermined time, the power supply control means 10 turns off the power supply from the power supply means 11 to the baseband processing part 3. Thus, a communication function of the mobile communication terminal device 100 is automatically stopped, thereby reducing power consumption. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
