Mobile communication terminal apparatus, method of controlling power consumption of mobile communication terminal apparatus, and recording medium

摘要

A first position information generation unit (130) generates, based on a first radio signal received by a first wireless communication unit (110), first position information representing a position where the first radio signal is received. A second position information generation unit (140) generates, using the first position information, second position information representing a position where a second wireless communication unit (120) can receive a second radio signal. A wireless communication operation determination unit (150) determines, based on the generated first and second position information, whether the operation by the second wireless communication unit is possible. A power supply control unit (160) executes power supply control of the second wireless communication unit in accordance with a determination result. This allows to uniquely determine the position information of a mobile communication terminal apparatus by simple signal processing at a low cost and implement power supply control of wireless communication functions based on the position information.

主权项

1. A mobile communication terminal apparatus comprising:
a first wireless communication unit configured to transmit and to receive a first radio signal; a second wireless communication unit configured to transmit and to receive a second radio signal to and from a second wireless communication base station; a first position information generation unit configured to generate, based on the first radio signal received by said first wireless communication unit, first position information representing a position where the first radio signal is received; a second position information generation unit configured to generate, as second position information representing a position where wireless communication is possible between said second wireless communication unit and the second wireless communication base station, the first position information generated by said first position information generation unit when said second wireless communication unit is transmitting or receiving the second radio signal, and is further configured to store the second position information in a storage unit; a wireless communication operation determination unit configured to determine, based on whether the first position information generated by said first position information generation unit matches with the second position information stored in the storage unit, whether a wireless communication operation by said second wireless communication unit is possible; and a power supply control unit configured to perform power supply control of said second wireless communication unit in accordance with a determination result of said wireless communication operation determination unit.
