Referring to FIG. 2, in a method of setting a remote lock function of a mobile communication terminal according to an embodiment of the present invention, a subscriber who has lost the mobile communication terminal 1 uses a web client 3 to perform a communication service provider network 2. The terminal reports the loss of the terminal by accessing the web server of the terminal, or directly accesses the communication provider network 2 by using the telephone to report the loss of the terminal directly.

At this time, the subscriber may apply for the remote lock function with the loss report of the terminal to the base station in the telecommunications network, and the base station stops the transmission of the mobile communication terminal 1 after receiving the loss report and the remote lock function request from the subscriber. The general page message (GENERAL PAGE MESSAGE) is transmitted to the mobile communication terminal 1 as a service option (SERVICE OPTION 18/19).

As a method for distinguishing each terminal, the base station uses a mobile identification number (MIN), an electronic serial number (ESN), an international mobile station identity (IMSI), and a broadcast (BROADCAST) according to an address type. Use separately.

The base station makes a call to the mobile communication terminal 1 using an address type and a page message type, and a general page message can call a number of terminals using MIN, ESN, IMSI, and BROADCAST. Message.

In this way, when a traffic channel is established between the mobile communication terminal 1 and the base station, the base station transmits an OTAPA request message (REQUEST MESSAGE) to the mobile communication terminal 1 (S2).

When receiving the OTAPA request message, the mobile communication terminal 1 starts the OTAPA connection by transmitting an OTAPA response message (RESPONSE MESSAGE) to the base station (S2).

When the base station transmits a VALIDATION REQUEST message for network authentication to the mobile communication terminal 1, the mobile communication terminal 1 receiving the verification request message transmits a VALIDATION RESPONSE message to the base station. (S3)

When the network authentication is completed, the base station transmits a lock function request OTA message instructing the user lock function setting to the mobile communication terminal 1, and the mobile communication terminal 1 receiving the lock function request OTA message is software-owned. The lock function is set (S4).

The mobile communication terminal 1 notifies the base station of the lock function request result OTA message, which is a result message for the success / failure of the setting of the lock function.

By doing so, the subscriber of the mobile communication terminal 1 does not need to enter a separate password, and can set a remote terminal lock function through an authenticated communication network regardless of whether a lost terminal is found by another person.

Meanwhile, in the method of releasing the remote lock function of the mobile communication terminal according to an embodiment of the present invention, when the user finds the lost mobile communication terminal again, the lock function may be released by inputting a password through the keypad of the mobile communication terminal. .

In this case, since the locking function of the mobile communication terminal is released but is stopped by the base station, the user can normally use the mobile communication terminal only by applying for the release of the stop.

Alternatively, when the user finds the lost mobile communication terminal and requests the base station to cancel the stop transmission and release of the terminal lock function for the mobile communication terminal, the lock function request OTA message / lock function of the terminal in step S4 of FIG. Instead of the request result OTA message, the base station transmits the lock function release OTA message to the mobile communication terminal, and the mobile communication terminal transmits the lock function release result OTA message to the base station after releasing the lock function.

In this way, when the transmission stop and lock functions of the mobile communication terminal are released, security can be increased while maintaining user convenience.

The drawings and detailed description of the invention are merely exemplary of the invention, which are used for the purpose of illustrating the invention only and are not intended to limit the scope of the invention as defined in the appended claims or claims.
