Abstract

A mobile terminal and a method for displaying user information when the mobile terminal is missing are provided so that a finder can get in touch with the owner of a lost mobile terminal. If a user accesses a communication service server using another terminal as the user finds his mobile terminal missing, the communication service server provides a voice mail service mode to the user(S300). Then the communication service server confirms whether the user inputs a specific character(S310). If the user inputs the specific character, the communication service server provides an input announcement to the user(S320). If the user inputs a number according to the provided announcement, the communication service server confirms whether the inputted number is the resident registration number of a user(S330). If it is confirmed that the inputted number is matched with the user's resident registration number, the communication service server requests the user to input a password(S340). If it is confirmed that an inputted password is matched with a stored password(S350), the communication service server sends a loss short message to the lost mobile terminal(S360).

The present invention relates to a mobile communication terminal control when lost, and more particularly, to a mobile communication terminal and a method of displaying a part of information including a user's contact information and preventing others from using the terminal by using a text message when lost. .

In general, a mobile communication terminal is mainly intended for making phone calls or text messages, but is equipped with various functions for users. For example, due to various multimedia and additional services, personal privacy information is stored in the terminal. For example, privacy information may include account numbers, passwords, and important notes.

  However, if a mobile communication terminal containing such important information is lost, information leakage occurs, so that a lock function method using a text message is used to prevent this. That is, the mobile communication terminal is locked or the terminal information is deleted by transmitting a text message including the control sentence to the mobile communication terminal.

However, this conventional method has a number of problems. Pointing out only a few of these, firstly, there was a concern that an arbitrary user would delete information of a terminal using a password of a voice message.

Secondly, if the lock is performed, there is no way for the learner to contact the loser. Therefore, in the worst case, a situation may occur in which the terminal may be discarded.

Lastly, when the terminal is initialized, important information stored in the terminal is lost even when the terminal is found.

SUMMARY OF THE INVENTION The present invention has been made in an effort to provide a mobile communication terminal and a method in which a learner can contact a lost person when the terminal is lost.

Hereinafter, with reference to the accompanying drawings will be described in detail an embodiment according to the present invention.

1 is a conceptual diagram showing a system for displaying limited user information when lost according to an embodiment of the present invention.

1, a mobile communication terminal 100 for receiving a lost text message and executing a lost mode, a communication service server 120 for sending a lost text message to the mobile communication terminal 100, and this communication service server ( And a second communication terminal 140 for sending the lost text message.

The mobile communication terminal 100 executes the set lost mode when receiving the lost text message. Of course, the process of setting a lost mode and storing it is required first. When the lost text message is received after the setting process is performed, the lost mode is performed. 2 is a view showing the structure of the mobile communication terminal 100 for this purpose.

Referring to FIG. 2, the mobile communication terminal 100 includes a control unit 200, a key input unit 210, a display unit 220, a message detection unit 230, a memory unit 240, an audio conversion unit 250, and a wireless device. Has a circuit portion 260.

The controller 200 controls functions implemented in the mobile communication terminal 100 and processes data and signals with other components. Particularly, in one embodiment of the present invention, when the user sets the lost mode, the user stores the lost mode message and receives the lost text message to execute the lost mode. In addition, if there is a request for canceling the lost mode, it is performed to restore the original mode. 4 is a diagram illustrating such a lost mode execution process. In addition, a diagram showing a lost mode release process is shown in FIG. Detailed description thereof will be described later in the corresponding drawings.

The key input unit 210 is a digit button (0-9), a special key button (*, # ....) used as an input from the mobile communication terminal 100, a letter key button engraved with the Korean alphabet or alphabet, Consists of a function key button to perform a function, and serves as an interface for transmitting a user's instruction to the controller 100. Of course, in the present invention, a key button for setting or releasing the lost mode may be separately configured. On the other hand, it is also possible to set or cancel the menu screen using a general key button without configuring a separate key button.

The key input unit 210 includes a lost shortcut key (not shown in the drawing) which can only be used to send a phone call or send a text message to the lost contact phone number. By selecting this lost shortcut key, you can make a phone call or send a text message to the loser's contact phone number so that you can easily contact the loser. At this time, if the contact number of the loser is a number may be a number of shortcut keys.

The display unit 220 may be formed of a display device such as a liquid crystal display (LCD), an organic light emitting diode (OLED), or the like, and may be controlled by the user of the mobile terminal according to the control of the controller 200. Displays the selected menu screen, the execution screen, and the result screen.

The display unit 220 may include a plurality of lost shortcut keys (604a, 604b, and 604c in FIG. 3c) capable of only making a phone call or transmitting a text message to a contact phone number of a lost person. Since the user selects any one of the plurality of lost shortcut keys (604a, 604b, and 604c in FIG. 3c), the user can make a phone call to a number of contact numbers that can be contacted with the loser or send a text message including pre-stored contact information. It's easy to get in touch.

In particular, an embodiment of the present invention displays a lost mode setting screen and a lost mode screen for setting a lost mode. A diagram showing this is shown in FIGS. 3A-3C.

3A and 3B illustrate screens for setting a lost mode. In FIG. 3A, a user inputs a message 600 and a contact 601 to be displayed on a terminal screen when lost. Of course, in addition to the user's phone number, the contact can also be configured to enter a phone number of family or friends.

In FIG. 3B, the user sets a function that the terminal can perform in a lost state. In other words, in this screen, the user selects only the necessary items as an option so that the function of the terminal can be limited in case of loss. For example, you can set call restriction, allow call, call only to his or her contact, write text or memo only. Of course, you can also set the lock all, and lock all is the default. In other words, if the user does not select an option, the mobile communication terminal 100 basically performs all lock functions.

 3C is a diagram illustrating a loss mode screen showing the loss mode set in accordance with FIGS. 3A and 3B. Also, in FIG. 3C, a plurality of lost shortcut keys (604a, 604b, and 604c in FIG. 3C) and a release menu 610 for releasing the lost mode are configured at the middle of the screen and at the bottom right of the screen.

When the message detector 230 receives the text message, the message detector 230 classifies the message into a general text message and a lost text message and notifies the controller 200 of the text message. Of course, the message detector 230 may be configured in the controller 200, or may be configured separately. The message detector 230 extracts the lost mode control data included in the lost text message and provides the same to the controller 200.

The memory unit 240 may be configured of a flash memory, a RAM, an electrically erasable programmable read only memory (EEPROM), and the like. To explain this, the basic real-time operating system (OS) and the call processing software of the mobile communication terminal are stored in the flash memory, and the variables and states of these programs are loaded from the RAM and operated. The ROM may be configured as an EEPROM, and may store nonvolatile data that may be electrically erased or stored again, and perform input / output according to a command of the controller 200.

In particular, the memory unit 240 stores the setting data if there is a setting for performing the lost mode function, and stores a program and data including an algorithm for executing the lost mode when the lost text message is transmitted.

The audio converter 250 converts the voice data received from the wireless circuit unit 260 into an audible sound through the speaker 251 under the control of the controller 200 and outputs the audible sound from the microphone 252. The voice signal is modulated and converted into digital voice data and transmitted to the controller 200.

The wireless circuit unit 260 receives a telephone call or data sent by an external telephone through the antenna 261 and transmits it to the control unit 200 or transmits data stored in the memory unit 240. That is, transmission and reception of voice or text data and control data are controlled. In particular, in one embodiment of the present invention receives the lost text message from the communication service server 120 and transmits it to the message detection unit 230.

Referring back to FIG. 1, the mobile communication terminal 100 having the configuration of FIG. 2 described above is connected to the communication service server 120 and the wireless communication network through the base station 110. The communication service server 120 is a server operated by a communication service provider and performs a process of transmitting a lost text message to the mobile communication terminal 100.

4 is a diagram illustrating such a transmission process. Prior to this description, a second communication terminal 140 connectable to the communication service server 120 is connected to the communication network 130 in order to transmit the lost text message. Of course, the communication network 130 may be a wired network or a wireless network. In addition, unlike the mobile communication terminal 100, the second communication terminal 140 may be a telephone or a wireless communication terminal which is a wired communication terminal.

That is, when the user loses the mobile communication terminal 100, the terminal requests a lost text message to the communication service server 120 by the phone or the wireless communication terminal to execute the lost mode for protecting the user information.

Referring to the lost text message transmission process in the communication service server 120, first, when the user of the mobile communication terminal 100 loses the terminal, the user using the second communication terminal 140, the communication service server 120 ) And enter the voicemail mode (step S300). That is, when the telephone service provider calls for a voice mail service, the communication service server 120 provides a voice mail mode to the user.

In this voicemail mode, the communication service server 120 checks whether the user inputs a specific character (step S310). That is, it is checked whether the key input is a specific character "0", which means sending a lost character message.

If the check result is a specific character, the communication service server 120 provides the user with input guidance (step S320). In this case, the input guide line will be a line for entering the social security number as an authentication process to confirm whether the user is a legitimate person.

When the user inputs a number according to this input guidement, the communication service server 120 checks whether the input number is the user's social security number (step S330).

If the social security number verification result number is identical, the communication service server 120 provides a comment for the user to enter the password again (step S340). In other words, there is a possibility that someone other than the real user may steal, so that an authentication procedure is applied to verify the social security number and password.

When the user inputs a number according to the password message, the communication service server 120 checks whether the input number and the stored password are the same (step S350).

If the password check result numbers match, the communication service server 120 transmits the lost text message to the mobile communication terminal 100 (step S360).

The above process is assumed to be input by a legitimate user, unlike the specific character input step (S310), social security number matching step (S330), password matching step (S350) if the input value is different, the user mistake Since the input value may be different, there is a process of inputting again with a few restrictions (step S311).

  In the embodiment of the present invention, the assumption of limiting to three inputs is made, but this is for understanding of the embodiment and various methods are possible.

Therefore, according to FIG. 4, when input is made within three times, the process proceeds to a specific character input step (S310), a social security number matching step (S330), and a password matching check step (S350) (step S312). On the contrary, if the input is more than three times, the communication service server 120 reports that the other person requests a lost text message instead of a legitimate user and ends the authentication process. Therefore, in this case, the lost text message is not transmitted to the mobile communication terminal.

When the lost text message is transmitted to the mobile communication terminal through the lost text message sending process of FIG. 4, the lost text message is received and executed in the lost mode, which is illustrated in FIG. 5.

The mobile communication terminal 100 receives a text message from the communication service server 120 (step S400). Of course, since the text message and the normal text message and the lost text message is received, the mobile communication terminal 100 checks whether the received text message is a lost text message (step S410).

If the received text message is a lost text message, the mobile communication terminal 100 displays the set lost mode screen (step S420). At the same time, the mobile communication terminal 100 executes the set lost mode (step S430). In other words, the lock function is executed. Of course, the locking function may be all locking functions or may be a limited lock function. This means that it is performed according to the setting selected in the lost mode setting screen as described above with reference to FIG. 2.

At this time, the loser's contact phone is repeatedly used by using a plurality of lost shortcut keys 604a, 604b, and 604c of the key input unit 210 or the display unit 220 capable of only making a phone call or transmitting a text message to the loser's contact phone number. You can send a phone call or text message to the numbers.

On the other hand, in the received text message checking step (step S410), if the received text message is a general text message, the mobile communication terminal 100 recognizes it as a general text message and stores it in the memory (step S411).

 6 is a flowchart illustrating a process of releasing the lost mode when the lost mode is executed in the mobile communication terminal 100 according to the aforementioned FIG. 5. That is, when the mobile communication terminal 100 returns to the user again, it is a flowchart showing a process of releasing a lost mode in which the user is running.

 Of course, for this purpose, it is necessary to have a resident number and password already entered and stored when setting the lost mode of the mobile communication terminal 100. Therefore, it is assumed in FIG. 6 that this process is already set.

When the user selects the termination 610 to terminate the lost mode on the screen of FIG. 3C, a screen for inputting the resident registration number is displayed (steps S500 and S510).

When the user enters the social security number on the social security number input screen, the mobile communication terminal 100 checks whether the stored social security number and the input number match (step S520). In other words, it is an authentication process to confirm whether the user is a legitimate person.

As a result of checking the input number, if the social security number and the input number match, the mobile communication terminal 100 provides a password input screen to the user (step S530).

When the user inputs a number on the input screen, the mobile communication terminal 100 checks whether the input number and the password match (step S540). In other words, in addition to the social security number verification process, there is a password verification process to form a dual authentication procedure.

If the password match check result is the input number and the password is matched, the mobile communication terminal 100 releases the lost mode (step S550). On the contrary, if the passwords do not match, the mobile communication terminal 100 maintains the lost mode. Of course, if the numbers do not match even in the input number confirmation step (S520) of the social security number is maintained in the same mode.

 As mentioned above, although this invention was demonstrated in detail using the preferable Example, the scope of the present invention is not limited to a specific Example, If the person who acquired the ordinary knowledge in this technical field, without departing from the range of this invention, It should be understood that many modifications and variations are possible. Therefore, the protection scope of the present invention will be preferably interpreted by the appended claims.

As described above, according to the present invention, it is possible for the learner to contact the lost person when the terminal is lost.

In addition, since the lost mode is executed, important information of the user is not stolen by others even if the terminal is lost.

In addition, even if the terminal has received the lost text message is lost when the terminal is not initialized.
