The present invention relates to a mobile communication terminal equipped with an unlocking function using an external mobile communication network and a method of controlling the same. Particularly, in the case where the password is lost while the lock function is set in the terminal, the wireless unlocking signal using the external mobile communication network is used. The present invention relates to a mobile communication terminal equipped with a unlocking function using an external mobile communication network for releasing a locking function of a terminal and a control method thereof.

In general, wireless data communication refers to a communication function of wirelessly transmitting and receiving various data such as letters, numbers, and images through a base station system using a portable terminal capable of wireless transmission and reception. For example, it is a mobile communication system that exchanges or retrieves data in both directions while moving by using various terminals such as a cellular phone, a portable computer, a facsimile, and a credit card inquiry machine. Especially in the early 1980s, mobile phones divided the service area into hexagonal cells of several km to several ten kilometers in diameter in North America, and then repeatedly used the same frequency channel in geographically separated cells. As a result, cellular phones that implement radio channel switching between cells have grown rapidly for the first time.

Then, referring to the conventional mobile communication system as described above with reference to FIG. 1, a base station 71 for wirelessly processing function signals transmitted from a plurality of terminals 70, for example, a call signal or an SMS message, and the base station ( 71, an MSC 72 for controlling a transmission function of a call signal or an SMS message input through the SMS signal, and an SMS server 73 connected to the MSC 72 to provide an SMS message to the terminal 70. .

On the other hand, referring to the operation of the conventional mobile communication system as described above, when the user of the terminal 70 presses the telephone number signal for the call, the telephone number signal is wirelessly signaled by the terminal 70 and the base station ( 72). Then, the base station 71 transmits the call signal of the input terminal 70 to the MSC 72. Then, the MSC 72 analyzes the input call signal data to recognize the destination telephone number and transmits the call signal to the base station 74 of the corresponding destination. Accordingly, the base station 74 relays the transmitted call signal and connects the call to the counterpart terminal 75. At this time, when a call is formed by the above process, the terminal 70 executes a normal call with the counterpart terminal 75.

Here, the conventional terminal 70 as described above is normally provided with a lock function, when setting the lock function of the terminal 70, calling the lock setting menu and entering the corresponding password, the terminal 70 authenticates this password. To execute the locking function of the terminal 70. In this case, when the lock function is set in the terminal 70, the radio call signal transmitted from the outside may be received, but the calling function is limited.

However, the conventional mobile communication terminal as described above does not release the lock function until after the password is authenticated in the menu even when the lock function is set and released after authentication by entering a password in the corresponding menu when setting the lock function. Because of this method, if the user loses the password of the terminal, there is considerable difficulty in using the calling function of the terminal. Also, in order to use the calling function again, there is a method of initializing all the inactive areas in which the password of the terminal is stored. When using this method, all information embedded in the terminal, for example, phone number or other data information, must be lost, which causes a problem of significantly deteriorating the stability of the internal information of the terminal.

Accordingly, the present invention has been invented to solve the above-mentioned conventional problems, even if the user loses the password in the state that the lock function is set in the terminal releases the lock function of the terminal through an external mobile communication network without any initialization. Therefore, the object of the present invention is to provide a mobile communication terminal equipped with a unlocking function using an external mobile communication network capable of maximizing the usability of the terminal and a control method thereof.

Still another object of the present invention is that even if the password for the terminal lock function is lost, it is not necessary to initialize all the inactive areas of the terminal, so that the information stored in the terminal does not need to be lost, thereby ensuring the stability of the built-in information of the terminal. The present invention provides a mobile communication terminal having a lock release function using a communication network and a control method thereof.

The present invention for achieving the above object is a mobile terminal equipped with a terminal lock function, the LCD is installed on a part of the body of the mobile terminal to display a message screen indicating the state that the lock function is released by the mobile communication network A panel unit, an MSM unit for wirelessly receiving and authenticating a wireless authentication signal for releasing the lock function, and releasing the lock function; and storing a password for releasing the lock function in an inactive area according to a storage control signal of the MSM unit. Provided is a mobile communication terminal equipped with an unlocking function using an external mobile communication network including a memory unit.

According to another aspect of the present invention, when a wireless call signal is received in a mobile communication terminal, a lock function release step of confirming whether the currently received wireless authentication signal is a signal for requesting release of the lock function, and confirming the wireless authentication signal release, the lock function release function. If the currently received wireless authentication signal is a signal for requesting the release of the lock function, the inactive area initialization step of initializing the inactive area of the memory unit of the terminal in which the existing password is stored, and after the inactive area initialization step Since the terminal has the password deleted, the control method of the mobile terminal equipped with the unlock function using the external mobile communication network consisting of the unlocking step of releasing the currently set lock function and displaying the unlock function fact on the display. to provide.

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

The apparatus of the present invention is installed on a part of the body of the mobile communication terminal 1 as shown in Figure 2 to display various information signals therein and to display a message screen indicating a state that the lock function is released by the mobile communication network And a wireless authentication signal for releasing the lock function, for example, an SMS signal or a data burst message, to wirelessly authenticate and release the lock function, and to determine the call connection status of the mobile communication terminal 1. The MSM unit 3 controls the overall information, and stores various information of the mobile communication terminal 1 in accordance with the storage control signal of the MSM unit 3, and stores a password for releasing the lock function in the inactive area. According to the call connection control signal of the memory unit 7 and the MSM unit 3, the analog voice signal input through the handset 4 is converted into a digital signal or the digital voice signal is converted into an analog signal. And a codec unit 5 for outputting the converted code.

One end of the MSM unit 3 is connected to a key panel unit 6 for inputting a function setting signal of the user to the MSM unit 3.

Next, a control method applied to the terminal of the present invention as described above will be described.

As shown in FIG. 3, the method of the present invention proceeds to the radio call signal reception determination step S2 in the initial state S1 to check whether the radio call signal is received from the outside at the current mobile communication terminal. At this time, if the radio call signal is not received at the current mobile communication terminal as a result of the determination during the radio call signal reception determination step (S2), the process proceeds to the general call processing function step (S3) to execute the general call processing function.

That is, when power is applied to the terminal 1 of the present invention, the MSM unit 3 of the terminal 1 proceeds to an initialization state, forms necessary information from the internal memory unit 7, executes an initialization process, and then waits. Proceed to state.

At this time, the MSM unit 3 of the terminal 1 recognizes when the user inputs a telephone number through the key panel unit 6 and presses a call button, and the user inputs the telephone number into the memory unit 7. In addition to the storage, the system accesses the base station 8 through the access channel, and then transmits an outgoing signal to the corresponding telephone number. Then, the base station 8 processes the outgoing signal sent from the terminal 1 and transmits an incoming signal to the counterpart terminal 9 to form a call.

That is, when the user of the terminal 1 inputs the voice signal through the handset 4, the codec unit 5 of the terminal 1 signals the voice signal input through the handset 4 to the MSM unit. Enter (3). In addition, the MSM unit 3 of the terminal 1 wirelessly processes the voice signal input through the codec unit 5 and transmits the voice signal to the counterpart terminal 9 via the base station 8 to make a normal call. do.

However, if the wireless call signal is received at the current mobile communication terminal as a result of the determination during the wireless call signal reception determination step (S2), the process proceeds to the unlocking function of the wireless authentication signal confirmation step (S4) to lock the currently received wireless authentication signal. Check if the signal requires the release of function. At this time, when the lock function release wireless authentication signal confirmation step (S4) is confirmed as a result of the received wireless authentication signal is not a signal requesting the release of the lock function, the current step ends and proceeds to the standby state. However, if the currently received wireless authentication signal is a signal for requesting the release of the lock function as a result of checking during the unlocking function of the wireless authentication signal release step (S4), the process proceeds to the inactive area initialization step (S5) of the terminal that stores the existing password. Initialize the inactive area of the memory section. After the inactive area initialization step (S5), the lock function release execution step (S6) proceeds to the terminal since the password is deleted, the currently set lock function is released and the lock function release fact is displayed on the display.

In other words, when the user of the mobile communication terminal 1 sets the lock function, the corresponding menu is called out through the key panel unit 6 and then a password is input. Then, the MSM unit 3 of the terminal 1 authenticates the password entered through the password located in the inactive area of the memory unit 7 and sets the lock function of the terminal 1 when authenticated. At this time, when the lock function is set in the terminal 1 as described above, it is possible to receive a radio call signal from the outside but can not make a call.

Here, when the user of the terminal 1 loses the password when the lock function is set, when the user of the terminal 1 notifies the fact to the service center of the terminal and is authenticated as the user of the terminal, the terminal 1 In the service center of the) through the base station (8) generates a wireless authentication signal requesting the release of the lock function in the form of an SMS signal or a data burst message and transmits to the terminal (1).

Then, the MSM unit 3 of the terminal 1 checks whether the currently received wireless authentication signal is a signal for requesting the release of the lock function, and if the received wireless authentication signal is a signal for requesting the release of the lock function, Initialize all of the inactive areas of the memory unit 7 of the terminal 1, the password of which is stored. Then, after initializing the password as described above, the MSM unit 3 of the terminal 1 releases the currently set lock function and displays the unlock function release fact on the LCD panel unit 2.

Here, the SMS signal, which is an example of the wireless authentication signals, may be configured as an indicator as a lock number initialization identifier (0 * 1111) or a payload area information as lock number initialization identification information. In addition, the data burst message, which is one example of the wireless authentication signal, may configure order as a lock number initialization identifier (0 * 11) or orderQ as lock number initialization identification information (0 * 11).

As described above, the present invention transmits a wireless unlock signal using an external mobile communication network when the password is lost while the lock function is set in the terminal, thereby releasing the lock function of the terminal. Even if the user loses the password in the state, the terminal unlocks the lock function through the external mobile communication network without any unconditional initialization, and thus has the advantage of maximizing convenience of use of the terminal.

In addition, according to the present invention, even if the password for the terminal lock function is lost, it is not necessary to initialize all the inactive areas of the terminal, and thus it is not necessary to lose the information stored in the terminal, thereby securing the stability of the built-in information of the terminal. have.
