Mobile communication terminal and terminal control method |
摘要 |
An object of the present invention is to surely and readily prevent unauthorized use of a noncontact IC function incorporated in a mobile communication terminal, even in a state in which no signal can be sent through mobile communication to the mobile communication terminal. A mobile communication terminal 10 has a noncontact IC module 12 incorporating an IC chip 11; a slot 13 in which a UIM 20 is to be loaded, the UIM 20 storing connection information to be used for connection between the host terminal 10 and a mobile communication network; a memory unit 15 for storing information to identify UIM 20; an acquiring unit 16 for acquiring information to identify UIM 20 loaded in the slot 13; a comparing unit 17 for making a comparison between the information to identify the UIM 20, stored in the memory unit 15, and the information to identify the UIM 20, acquired by the acquiring unit 16; and a control unit 18 for controlling access to the IC chip 11, based on a result of the comparison by the comparing unit 17. |
