<p><P>PROBLEM TO BE SOLVED: To provide a remote locking system capable of further rapidly and surely performing remote locking to a stolen mobile communication terminal such as a cellular phone or a stolen information processing terminal having a communication function. <P>SOLUTION: In this remote locking system, when making a position registration request to a communication network side including a base station 51, the mobile communication terminal 2 determines whether remote locking instruction information is included in a signal received from the communication network side in an authentication phase. If included, a function of accessing user data 31 and the function of an input/output section are stopped. Upon receiving the position registration request from the mobile communication terminal 2, the communication network side refers to a subscriber information database 46 to transmit remote locking instruction information when a locking instruction is set in the mobile communication terminal 2. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
