Abstract
A first position information generation unit () generates, based on a first radio signal received by a first wireless communication unit (), first position information representing a position where the first radio signal is received. A second position information generation unit () generates, using the first position information, second position information representing a position where a second wireless communication unit () can receive a second radio signal. A wireless communication operation determination unit () 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 () 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.
