However, the present invention is not limited to the contents described below, it should be noted that it can be applied to various embodiments based on the following embodiments.

3 is a diagram illustrating a tracking method of a mobile terminal according to an exemplary embodiment of the present invention.

Referring to FIG. 3, first, as shown in step S301, the SIM card is mounted through the interface unit of the portable terminal. When the portable terminal is powered on in step S303, the controller of the portable terminal performs step S305. In step S307 after extracting the SIM card information on the SIM card mounted through the interface unit, comparing the extracted SIM card information with the SIM card information set in the memory unit. Here, in steps S301 to S303, the present invention does not necessarily operate by the above-described procedure, and it is obvious that the SIM card may be mounted after the power is turned on.

In addition, the embodiment of the present invention may further include determining whether to activate or deactivate the mobile terminal tracking function before step S305. As a result of the determination, when the portable terminal tracking function is activated, the process proceeds to step S305. When the determination result, the portable terminal tracking function is deactivated, the procedure may be omitted and the procedure proceeds to step S309. That is, according to an embodiment of the present invention, a setting menu may be set to enable or disable the tracking function for the portable terminal when the SIM card is mounted for convenience of the portable terminal. This allows the mobile terminal tracking function to be activated or deactivated arbitrarily according to the user's convenience in preparation for the loss of the mobile terminal.

Next, as shown in step S307, if the extracted sim card information and predetermined sim card information match, the process proceeds to step S309 and the controller performs a normal booting procedure of the portable terminal. For example, the controller controls loading of the phone book information stored in the SIM card into the memory unit. In detail, when booting the portable terminal, the controller reads a SIM card through an interface unit to which the SIM card is connected, and checks SIM card information (eg, ICCID) for the SIM card. If the SIM card information does not match the previously stored SIM card information, the SIM card is recognized as a change. If the SIM card information matches the SIM card information, the phone book information is read and the phone book information is stored in the memory unit. Load.

On the other hand, if the extracted SIM card information and the preset SIM card information do not match as shown in step S307, the process proceeds to step S311 to extract the setting information stored in advance in the memory unit along with the normal booting of the mobile terminal. That is, the controller controls the tracking function of the mobile terminal if the SIM card information does not match the preset SIM card information, and extracts the setting information stored in the memory unit for generating and transmitting a text message.

Next, the controller generates a text message in step S313 based on the setting information extracted in step S311, and transmits the generated text message to the recipient's telephone number according to the setting information. In this case, according to an embodiment of the present invention, when the sim card information extracted in step S307 and the preset sim card information do not match, the use of the portable terminal may be restricted based on a user setting. In addition to the use restriction of the mobile terminal, it is also possible to transmit a text message set as in steps S311 to S313.

The text message may also include preset caller information and message contents, including SIM card information on a SIM card currently installed in the mobile terminal, and identification information (eg, IMEI) assigned to the mobile terminal to uniquely identify the mobile terminal. Etc.) may be further included.

4 is a diagram illustrating a process of setting a tracking function in a mobile terminal according to an embodiment of the present invention, and FIGS. 5 to 7 are diagrams illustrating an example of a function setting screen for tracking of a mobile terminal according to an embodiment of the present invention. .

In FIG. 4, the procedure of installing the SIM card in the portable terminal will be omitted. Therefore, in FIG. 4, a case where the SIM card is mounted and the mobile terminal is normally booted as in step S401 will be described as an example. In addition, FIG. 4 illustrates a user interface menu entry and setting process for setting a tracking function (eg, a 'mobile tracker' function) of the mobile terminal according to the present invention as described above.

Referring to FIG. 4, first, after normal booting of the mobile terminal in step S401, the controller performs setting for a tracking function (hereinafter, referred to as a "tracking function") of the mobile terminal from the user as shown in step S403. If there is no request signal, the operation proceeds to step S405 and the operation according to the normal booting and the corresponding operation requested by the user. When the request signal for setting the tracking function is input, the operation proceeds to step S407.

In step S407, the controller determines whether the tracking function setting request is an initial setting. For example, the 'initial setting' is as follows. For example, a user may purchase the portable terminal and the SIM card, and set the tracking function in preparation for the loss of the portable terminal. In this case, when the user enters a menu for setting a tracking function and activates the tracking function (for example, when the mobile tracker is turned on as shown by reference numeral 620 of FIG. 6), the controller is mounted on the portable terminal. Sim card information for the first user sim card may be stored in a memory unit. As described above, the initial setting indicates that SIM card information regarding a user SIM card is initially set in the portable terminal. This is only an embodiment of the present invention and the present invention is not limited thereto. In addition, through any user authentication procedure, the SIM card information of various SIM cards desired by the user may be stored in advance in the memory unit.

If it is determined in step S407 that the tracking function setting request is not the initial setting, the controller proceeds to step S417 and requests a password input. When the requested password is input in step S417, the controller proceeds to step S419 to compare a preset password with the input password and determine whether there is a match.

If the result of the determination in step S419 matches, the process proceeds to step S411 to display a tracking function setting screen and receives input of setting information (eg, activation / deactivation setting of the tracking function, modification of setting information, or additional information) requested by the user. A screen embodiment thereof is shown in FIG. 6, which will be described later.

If the result of the determination in step S419 does not match, the process proceeds to step S421 to display a warning message indicating that the password does not match. Thereafter, the controller may request a password input request more than a predetermined number of times, and if the password does not match for more than the predetermined number of times, the controller may restrict entry to the tracking function setting menu. That is, the controller may perform a password input re-request or a security operation as in step S423.

A screen embodiment for entering a menu for setting the tracking function and a corresponding authentication process (for example, the password input request, comparison, and a proceeding procedure thereof) is shown in FIG. 5. As illustrated in FIG. 5, when a menu selection signal (eg, a 'mobile tracker' menu indicated by reference numeral 510) for setting a tracking function of a portable terminal is input from a user at reference numeral 510, the controller refers to reference numeral 520. A password input screen is displayed to request password input. Thereafter, when an arbitrary password is input from the user, the controller determines whether the previously stored password matches the input password as shown by reference numeral 530. At this time, if the password does not match, a random warning message is displayed as shown by reference numeral 540, and when the password is matched, a setting screen for setting the tracking function of the mobile terminal is displayed as shown by reference numeral 550. FIG.

Next, if it is determined in step S407 that the tracking function setting request is the first setting, the controller proceeds to step S409 to extract sim card information (eg, ICCID) for the installed SIM card and The extracted SIM card information is stored in the memory unit.

On the other hand, Figure 4 is described as an example of automatically setting the SIM card information when the tracking function is activated, but the present invention is not limited thereto. For example, the user may further include setting SIM card information for his SIM card. Therefore, the controller provides a menu for setting the SIM card information according to the user's request, extracts the SIM card information mounted in the portable terminal based on a signal selected / input from the user in the menu, and extracts the SIM card information. It can be set in the memory section.

In addition, although not shown in FIG. 4, if it is determined as the first setting in step S407, the controller may request a password input before proceeding to step S409. In this case, the password input request step is a process for user authentication according to the entry of the tracking function by initial setting, and the set password compared to the input password may be a basic password provided when the portable terminal is manufactured. Therefore, the user can check the password requested in the process at the time of purchase of the portable terminal, and when the password input request is made, the user can input the confirmation password to perform user authentication. Also, after the user authentication, a process of changing the user's desired password may be performed. This process is not necessarily included in the present invention, which may be optionally performed.

Thereafter, the control unit proceeds to step S411 to display the tracking function setting screen and receive input of setting information (eg, activation / deactivation setting of the tracking function, recipient phone number, caller information, message content, etc.) requested from the user. A screen embodiment thereof is shown in FIG. 6, which will be described later.

Next, the controller determines whether the function setting is completed in step S413. That is, in step S413, the controller determines whether a completion signal for setting the function is input.

If it is determined in step S413 that the function setting is not completed, the process proceeds to step S411 to perform a setting information input process. When the determination result function setting is completed in step S413, the controller proceeds to step S415 and stores the received setting information in the memory unit.

6 to 7 illustrate screen examples of steps S411 to S413. As shown in FIG. 6, when the input password matches, the controller displays a tracking function (eg, 'mobile tracker') setting screen of the mobile terminal as shown by reference numeral 610. In this case, when an input signal for activating / deactivating the tracking function is generated through an input unit on the function setting screen displayed as indicated by reference numeral 610, the controller crosses the screen such as reference numeral 620 or 610. In this case, when the tracking function setting of the reference numeral 620 is the initial setting as described above, the controller extracts the SIM card information (eg, ICCID, etc.) of the mounted SIM card and stores it in the memory unit.

Next, when the receiver information input field is selected based on the user's selection signal, the controller activates the receiver information input field as shown by reference numeral 630, and thereafter, when the selection signal for the activated receiver information input field is generated, Likewise, the subfield of the receiver information input field is displayed. For example, the form may be input by a user directly through an operation of the input unit or by a search method in a receiver information input field such as the reference numeral 630.
