The present invention relates to a mobile communication terminal, and to a mobile communication terminal capable of function control at a remote location.

Recently, a widely used mobile communication terminal has functions such as a telephone call function, a wireless Internet access function, a phone book, and the like. Users can use the mobile communication terminal to make a phone call with a receiver located at a remote location while moving, and send and receive messages.

In such mobile communication terminals, cases of loss caused by owners' mistakes are frequently generated. The owner who has lost the mobile communication terminal should report the loss to the mobile communication provider to prevent unauthorized use of the acquirer.

In addition, the mobile communication terminal may be returned from the acquirer of the lost terminal by attempting a telephone call to the lost mobile communication terminal without reporting the loss.

However, in the case of a malicious learner, an unfair use fee may be transferred to the owner by unauthorized use of the acquired mobile communication terminal without returning it to the owner.

In order to prevent this, conventionally, a method of restricting only a calling function of a lost mobile communication terminal or allowing a locking function to be executed by default has been used.

However, if only the calling function is limited, the recent generalized toll charge type phone call cannot be suppressed. In addition, there remains a problem in that the payment of an unfair communication fee is forced on the owner.

In addition, in the case of limiting the reception function in order to suppress a telephone call of the toll charge type, there is a problem that the owner cannot attempt to make a telephone call to the lost mobile communication terminal. That is, when both the calling function and the receiving function are restricted, the owner who loses the mobile communication terminal may be unable to recover the mobile communication terminal itself. As such, if the lost owner cannot recover the mobile communication terminal, not only waste of unnecessary resources but also increase in the total amount of royalties provided to prominent overseas companies may be caused.

Accordingly, an object of the present invention for solving the above problems is to provide a mobile communication terminal having an unauthorized use suppression function capable of suppressing unauthorized use by a learner's malice even if the mobile communication terminal is lost.

1 is a block diagram showing the configuration of a mobile communication terminal having an unauthorized use suppression function according to an embodiment of the present invention.

Referring to FIG. 1, a mobile communication terminal 100 according to an exemplary embodiment of the present invention includes an antenna unit 110, a wireless circuit unit 115, an audio processor 120, a handset 125, and a display 130. , A key input unit 135, a memory unit 140, a message analyzing unit 145, a mode processing unit 150, and a control unit 155. It is apparent that some components of the mobile communication terminal 100 (eg, the message interpreter 145, the mode processor 150, etc.) may be implemented in the form of a software program. In addition, it is apparent that some components (eg, the message interpreter 145, the mode processor 150, etc.) may be implemented in an integrated form.

The antenna unit 110 transmits a transmission signal (for example, a user's voice signal, a telephone call request, a message transmission request, a wireless Internet access request, etc.) received from the wireless circuit unit 115 to a mobile communication service system (not shown). And a radio signal (for example, a voice signal of another user, a message reception request, etc.) is received from the mobile communication service system and transferred to the radio circuit unit 115.

The wireless circuit unit 115 receives a voice signal, a message, and the like from the mobile communication service system through the antenna unit 110 and transmits it to the controller 155, and inputs it through the handset 125 under the control of the controller 155. The voice signal, a phone call request, a message, etc. input through the key input unit 135 are transmitted to the antenna unit 110.

The audio processor 120 processes the voice input by the user of the mobile communication terminal 100 through the handset 125 as data and transmits the data to the controller 155, and transmits the voice signal received through the antenna unit 110. Processing to output the analog voice through the handset 125.

The handset 125 may include a handset such as a microphone and a handset such as a speaker. The microphone is a means for receiving a voice of the user of the portable terminal 100, and the speaker is a voice signal of another user received from the mobile communication service system through the antenna unit 110, and any key button provided in the key input unit 135. It is a means for outputting a sound or the like corresponding to the selection.

The display unit 130 displays an operation state, time information, a received message, and the like of the portable terminal 100. The display unit 130 may be, for example, a liquid crystal display.

The key input unit 135 may be composed of a touch screen or one or more key buttons. The key input unit 135 may serve as a medium for transmitting a user's instruction to the control unit 155.

The memory unit 140 may be configured of, for example, a flash memory, a RAM, a ROM, or the like. The flash memory stores a real-time operating system (OS) and call processing software. Variables and states of these programs can be read and operated from RAM. In addition, the flash memory is a non-volatile memory that has a high processing speed and data is preserved, and new software is stored in this part when upgrading the software of the mobile communication terminal 100. The ROM may be configured as an EEPROM, store nonvolatile data, and perform input / output under the control of the controller 155. The ROM may store NAM (Number Assignment Module) parameters, other storage data (eg, phone number, name, text message, etc.) that can be used semi-permanently without being erased.

The message analyzing unit 145 determines whether the message received through the antenna unit 110 is a lost message including a preset format and / or contents, and requests the mode processing unit 150 to perform the lost mode when the message is a lost message. do. The lost message is a message written in a preset format and / or content for performing the lost mode, and the type of the message is not limited to SMS and MMS. For example, the message interpreter 145 may recognize that the message is a lost message if the message includes a preset registration message (eg, “report loss”). Or a message containing a function character (eg, #) to perform an arbitrary function (eg, "lost report #"), the content text corresponding to that function character (ie, lost report) If the extracted character matches the preset registration message, it may be determined as a lost message. In addition, the message interpreter 145 may determine whether the message is a lost message only when the message is received from a preset phone number in order to eliminate the decrease in efficiency for analyzing all received messages. In addition, it is obvious that the message interpreter 145 may further apply various methods for determining whether the received message is a lost message.

The mode processing unit 150 switches the operation mode of the mobile communication terminal 100 to the lost mode when a loss mode execution request is input from the message analyzing unit 145. When the mode is switched to the lost mode, the mode processing unit 150 restricts the use of the transmission, the use of the contents, the use of the personal information or the phone book stored in the memory 140, etc. in order to prevent unauthorized use of the learner. In addition, a general call is also prohibited for the reception function, and the reception is limited only to reception requests from telephone numbers registered by the user and / or telephone numbers registered in the phone book. That is, it is sufficient for the user to register a phone number (for example, a home or work phone number or a friend's phone number) that can be easily attempted to make a phone call to the mobile terminal 100 in preparation for loss. . At this time, the telephone number that can be registered may be one or more. The mode processing unit 150 performs a normal telephone call in response to a request for reception from a registered telephone number, and suppresses unauthorized use of the learner by maintaining a lost mode when the telephone call is terminated.

The control unit 155 is the antenna unit 110, the wireless circuit unit 115, the audio processing unit 120, the transmission unit so that the mobile communication terminal 100 according to the present invention can perform the loss mode to prevent unauthorized use of the learner The sign language unit 125, the display unit 130, the key input unit 135, the memory unit 140, the message analyzing unit 145, and the mode processing unit 150 are controlled.

2 is an exemplary diagram of a user interface (UI) screen for setting a lost mode according to an exemplary embodiment of the present invention.

As illustrated in FIG. 2, a user may set a loss mode using a preset loss mode setting window. The lost mode setting window may be displayed on the display unit 130 using menu items displayed by selection of a menu button. For example, the lost mode setting window may include a message registration item for registering the contents of a lost message, an allowable phone number item for registering a phone number that is allowed to be received in the lost mode, and a password setting item for releasing the lost mode. It may include. Password (ie, password for lost mode setting) authentication may be preceded before display of the lost mode setting window.

When the user selects a message registration item, the message registration window 210 is displayed on the display unit 130. The user may register arbitrary words (hereinafter, referred to as a registration message) for causing the mobile communication terminal 100 to operate in the lost mode using the message registration window 210. If the user does not register any words as a registration message for entry into the lost mode, the words preset in default may function as the registration message.

In addition, when the user selects a reception allowable phone number item, the display unit 130 displays a phone number designation window 215 for registering a phone number to allow reception in the lost mode operation. The phone number designation window 215 is configured to allow a user to designate any phone number and / or phone numbers registered in the phone book as a reception allowable phone number.

In addition, when the user selects a password setting item, the display unit 130 displays a password setting window 220 for releasing the lost mode operation. When the mobile communication terminal 100 is switched to the lost mode by the received message, a password specified through the password setting window 220 should be input to release the lost mode. If the user does not specify a password through the password setting window 220, a preset default password (for example, 0000) may function as a password for unlocking.

In addition, the lost mode setting window may further include a phone number input item for setting in advance a phone number to transmit the lost message. By inspecting only the message received from the telephone number input through the telephone number input item, the number of messages to be inspected can be minimized, and as a result, the processing efficiency of the mobile communication terminal 100 can be maximized.

3 is a flowchart illustrating a method of performing a lost mode according to an exemplary embodiment of the present invention.

Referring to FIG. 3, in step 305, the mobile communication terminal 100 receives a message from a mobile communication service system through a communication network. The format of the message may be applied without any limitation as long as it is a message format that may include one or more character and / or numeric data.

In step 315, the mobile communication terminal 100 determines whether the received message is a lost message. Methods for determining whether a received message is a lost message are various in the mobile communication terminal 100. First, a method of searching for the content of a message and determining whether there is a registration message (see 210 of FIG. 2) previously set for switching to a lost mode may be used. Second, determine if there is a function character (e.g., #) set to retrieve the contents of the message to perform an arbitrary function, and if so (e.g., "Report Lost"). A method of extracting a corresponding content text (ie, missing report) and determining whether the text matches a preset registration message may be used. Third, it may be determined whether the received message is a message received from a preset telephone number, and whether the received message is a lost message using the first or second method described above only when the received message is received from the telephone number.

If it is not a lost message as a result of the determination in step 315, the mobile communication terminal 100 stores the message received in step 320.

However, if the received message is a lost message, the process proceeds to step 325 where the mobile communication terminal 100 switches the operation mode to the lost mode. When the lost mode is switched, as described above, a specific function (for example, a calling function, a receiving function for most calling numbers, a wireless Internet function, a personal information reading function, etc.) among the functions of the mobile communication terminal 100 is performed. This is limited.

In step 330, the mobile communication terminal 100 determines whether a call request for any telephone number input from the user is input.

When the originating request is input, the flow proceeds to step 335 and the display unit 130 displays a preset error message (for example, "sending is restricted while the lost mode is being performed.").

However, if the originating request is not input, the flow proceeds to step 340 to determine whether a receiving request from any originator is received from the mobile communication service system. The incoming request is for a phone call request and generally includes the telephone number of the calling party's terminal.

If the reception request is not received, the flow proceeds to step 330 again.

However, when the reception request is received, the process proceeds to step 345 to determine whether the telephone number included in the reception request is a reception permission telephone number (see 215 of FIG. 2).

If it is not the reception permission telephone number, the process proceeds to step 335 and displays a preset error message on the display unit 130. Of course, if it is not the reception permission telephone number, it may not perform any operation (for example, ringtone output, etc.) for reception of the reception request. Through this, it is possible to suppress the call charge attempts that are becoming common recently.

However, in the case of the reception allowable phone number, the flow proceeds to step 350 to perform any general reception operation (for example, outputting a ring tone, initiating a telephone call in response to the learner).

As described above, a mobile communication terminal having an unauthorized use suppression function according to the present invention has an effect of suppressing unauthorized use by a learner's malice even if the mobile communication terminal is lost.

In addition, the present invention has the effect that the owner can easily recover the lost mobile communication terminal.

In addition, the present invention has the effect of facilitating the recovery of the lost mobile communication terminal to suppress waste of unnecessary resources and outflow of foreign currency.

Although the above has been described with reference to a preferred embodiment of the present invention, those skilled in the art to which the present invention pertains without departing from the spirit and scope of the present invention as set forth in the claims below It will be appreciated that modifications and variations can be made.
