5 is a flowchart illustrating a preferred embodiment of a method for controlling the operation of a mobile phone according to an SMS message received according to the present invention. First, the controller 110 determines whether an SMS message is received by the receiver 180 through an antenna (S110). If it is determined that the SMS message is not received, the control unit 110 maintains the operation standby mode of the mobile phone (S120).

If it is determined that the SMS message is received, the control unit 110 determines the type of the received message through the header code of the received SMS message (S130). Accordingly, the controller 110 determines whether the received SMS message is a control message (S140). According to the determination result, if it is determined that the SMS message is only 10,000 SMS messages, the controller 110 performs processing of general SMS messages such as displaying the received SMS message on the display unit 130 and storing the received SMS message in the storage unit 140. (S150).

If it is determined that the received SMS message is a control message, the controller 110 detects an access code for access to a code set for controlling the mobile phone from the SMS message, and the detected access code is stored in the storage 140. The comparison unit 150 is controlled to check whether the code matches (S160). The controller 110 determines whether the access codes match according to the comparison result of the comparator 150 (S170). If it is determined that each access code does not match, the controller 110 discards the SMS message because it is impossible to control the mobile phone by the received SMS message (S180).

If it is determined that the access codes match, the control unit 110 reads the code value from the preset lookup table, detects the control code value from the SMS message, and sets the matched code value as the control code value (S190). When the control code value is set, the controller 110 detects control data corresponding to the control code value set from the lookup table and controls the operation of the mobile phone according to the detected control data (S200).

Therefore, as the control message for controlling the operation of the mobile phone is received by the SMS message to the mobile phone away from the user, the operation of the mobile phone can be remotely controlled by the user by controlling the operation of the mobile phone through the received control message. .

First, the controller 110 determines whether an SMS control message for controlling the operation of the mobile phone is received (S310). If it is determined that the SMS control message is not received, the control unit 110 maintains a standby mode waiting for the operation of the mobile phone (S320).

If it is determined that the SMS control message has been received, the controller 110 determines whether the received SMS control message is a lost control message according to the loss of the mobile phone (S330). If it is determined that the received SMS control message is not the lost control message, the controller 110 controls the operation according to the type of the message (S340).

If it is determined that the received SMS control message is a lost control message, the controller 110 switches the operation mode of the mobile phone to the SMS reception function mode for receiving only the SMS message (S350). In addition, the controller 110 switches the operation mode of the mobile phone to the software download lock mode for suppressing software download (S360).

When the operation mode of the mobile phone is switched to the SMS receiving function mode and the software download lock mode, the controller 110 performs a hardware reset for rebooting the mobile phone (S370). At this time, the power is turned off when the hardware is reset. When the mobile phone is reset and the power is turned off, the controller 110 determines whether the preset power supply operation mode of the mobile phone is an automatic power on mode for automatically reapplying power after the power is turned off (S380).

If it is determined that the mode is not in the automatic power on mode, the controller 110 maintains the power off (OFF) to maintain the off state without supplying power to the mobile phone (S390). If it is determined that the automatic power-on mode, the controller 110 resets and reapplies the power to the mobile phone that is powered off to automatically turn on the power (S410). At this time, when the power is turned on again and the mobile phone is initialized, the controller 110 maintains the operation mode of the mobile phone in the lost control mode (S420). In this case, the loss control mode is a control mode in which the mobile phone performs only a function of receiving an SMS while the mobile phone is in operation and suppresses the mobile phone from downloading software.

If a control message for releasing the loss control is received while the cellular phone maintains the loss control mode, the cellular phone switches the lost control mode to the lost release mode to perform the operation of the general cellular phone.

Therefore, by recognizing that the user lost the mobile phone and transmitting a loss control message to his mobile phone, it is possible to prevent the use of the mobile phone by others due to the loss of the mobile phone.

According to the present invention, the control code corresponding to the restriction list and the restriction list for controlling the operation of the mobile phone is edited and updated to a look-up table, so as to remotely control the control code on its own mobile phone using a communication terminal such as another mobile phone. You can control your phone by sending an SMS.

In addition, by receiving a control message for controlling the operation of the mobile phone by SMS message to the mobile phone away from the user by controlling the operation of the mobile phone through the received control message, the operation of the mobile phone can be controlled by the user remotely. .

In addition, by recognizing that the user lost the mobile phone and transmitting a loss control message to his mobile phone, it is possible to prevent the use of the mobile phone by others due to the loss of the mobile phone.
