The present invention relates to a mobile communication terminal with a copy protection function and a control method thereof. In particular, the mobile station and the base station store the current call records separately and simultaneously, and when the new call is requested, the base station transfers the previous call records to the terminal. The present invention relates to a mobile communication terminal having a copy protection function which transmits and compares these call records with each other and displays the copy externally to determine whether the call is duplicated.

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 Figure 1, the base station (71, 72) for wirelessly processing function signals, for example, call signals or SMS messages transmitted from a plurality of terminals 70, and MSC (73) for controlling the transmission function of the call signal or SMS message input via the base station (71, 72). Here, the base station 71, 72 authenticates the electronic serial number (ESN) of the terminal 70 in its cell, and then processes the call signal requested by the terminal.

On the other hand, referring to the operation of the conventional mobile communication terminal as described above, first, when the user of the terminal 70 opens the folder 74 and presses the telephone number signal through the keypad 75, the telephone number signal is the LCD panel ( At the same time as displayed on the 76, the radio signal is processed by the terminal 70 and transmitted to the base station 71. The base station 71 authenticates the ESN information input from the terminal 70 and then transmits the corresponding call signal to the MSC 73. Then, the MSC 73 analyzes the input call signal data to recognize the destination telephone number and transmits the call signal to the base station 72 of the corresponding destination. Accordingly, the destination base station 72 relays the transmitted call signal and connects the call to the counterpart terminal 77. At this time, when the call is formed by the above process, the terminal 70 executes a normal call with the counterpart terminal 77.

In addition, when the user of the terminal 70 sets a specific function such as a wake-up call function or an MP3 file playback function through the keypad 75, the terminal 70 displays a corresponding menu screen on the LCD panel 76. . Here, when the user of the terminal 70 sets a wake-up call function, for example, the user of the terminal 70 sets the time and ring tone information while viewing the corresponding menu screen displayed on the LCD panel 76. Then, the terminal 70 stores the input morning call information and then emits the morning call signal to the outside when the corresponding time is reached. Therefore, the user of the terminal 70 hears the morning call signal and wakes up from the seat.

However, the conventional mobile communication system as described above is a method in which the base station processes all call signals only if the base station authenticates the ESN of the terminal. Therefore, this ESN can be used without restriction as if the terminal owned by the original owner. The use of the duplicated terminal was imposed on the owner of the terminal such as a huge amount of financial damage to the owner of the terminal as well as the user of the terminal can not find out quickly and effectively there was a problem that significantly reduces the security of the terminal accordingly.

Accordingly, the present invention has been invented to solve the above-mentioned conventional problems, and the user of the actual terminal checks the difference between the base station displayed on the terminal and the call record on the terminal, and determines whether the terminal is duplicated. Therefore, the object of the present invention is to provide a mobile communication terminal with a copy protection function and a control method thereof, which can significantly improve the security of the terminal.

 Another object of the present invention is to provide a mobile communication terminal and a method of controlling the same with a copy protection function, which allows the user to quickly check whether the terminal is duplicated without adding a complicated circuit configuration. To provide.

The present invention for achieving the above object is a mobile communication terminal for performing a call processing function, which is installed on a part of the body of the mobile communication terminal received the previous call record received from the base station system unit and the corresponding call record of the terminal An LCD panel unit for displaying and an MSM unit for displaying a call record of a call signal processed by the mobile communication terminal and a call record received from a base station system unit on the LCD panel unit so that a user can compare with each other; According to the storage control signal of the MSM unit provides a mobile communication terminal having a copy protection function including a memory unit for storing the call record after the call execution.

Another feature of the present invention is the step of executing a first call function to receive a call from the base station system unit when the call function is set in the mobile communication terminal to process a call signal and to store the processed call record in a memory; A second call function execution step of receiving a call from a base station system unit to process a call signal and storing the processed call record in a memory when another second call function is set in the current terminal after the call function execution step; Copy protection comprising a copy discrimination information display step of displaying on the display a record of the first call made immediately before the second call after the second call function execution step and a record of the second call received from the base station corresponding thereto; Provided is a control method of a mobile communication terminal having a function.

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

The apparatus of the present invention is installed in a part of the body of the mobile communication terminal 1 as shown in FIG. 2 and displays the previous call log received from the base station system unit 8 and the call log of the terminal corresponding thereto. LCD panel 2 for displaying various information signals processed by the outside, call records of call signals processed by the mobile communication terminal 1, and call logs received from the base station system unit 8 corresponding thereto. Are displayed on the LCD panel 2 so that the user can compare with each other, the mobile station modem (MSM) (3) and the storage control of the MSM (3) to control the overall function of the mobile communication terminal (1) Memory unit 4 for storing the call record after the call is executed according to the signal and the analog voice signal inputted through the handset 5 according to the call connection control signal of the MSM unit 3 is converted into a digital signal or Digital audio signal And a codec unit 6 for converting and outputting the analog signal.

One end of the MSM unit 3 is connected to a key panel unit 7 for inputting a function setting signal of the user to the MSM unit 3.

Next, a control method of the system having the above configuration will be described.

As shown in FIG. 3, the method of the present invention proceeds from the initial state S1 to the first call function setting checking step S2 to check whether the call function is set in the current terminal. At this time, if the call function is not set in the current terminal as a result of checking during the first call function setting confirmation step (S2), the current step ends and proceeds to the standby state. However, if the call function is set to the current terminal as a result of the check during the first call function setting confirmation step (S2), the process proceeds to the first call function execution step (S3) to process a call signal by receiving a call from the base station system unit. The processed call log is stored in the memory.

Here, in the first call function execution step (S3), the current call is completed, and the terminal stores the call record for the current call, and at the same time, the base station system unit stores the first call record base station storing step corresponding thereto. It further includes.

In addition, after the first call function execution step (S3), and proceeds to the second call request confirmation step (S4) to confirm whether another second call function is currently set in the terminal. At this time, if another second call function is not set in the current terminal as a result of checking during the second call request setting confirmation step (S4), the current step ends and proceeds to the standby state. However, if another second call function is currently set in the terminal as a result of checking during the second call request setting confirmation step (S4), the process proceeds to the second call function execution step (S5) and receives a call from the base station system unit. Processes the call signal and stores the processed call log in memory.

Here, in the second call function execution step (S5), the current call is completed, the terminal stores the call record for the current call, and the base station system unit stores the call record corresponding thereto and also stored the base station system unit. And a second call record base station processing step of transmitting the previous first call record to the corresponding terminal.

On the other hand, after the second call function execution step (S5) proceeds to the duplicate discrimination information display step (S6) to record the first call made just before the second call and the second call received from the base station corresponding thereto The record is displayed on the display.

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 initial state and forms necessary information including the ESN from the memory unit 4 to form the base station system unit 8 ) To execute the initialization process and then to the standby 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 7 and presses a call button, and the user inputs the telephone number to the memory unit 4. In addition to the storage, the system accesses the base station system unit 8 through the access channel, and then transmits an outgoing signal to the corresponding telephone number. Then, the base station system unit 8 processes the outgoing signal sent from the terminal 1 and transmits an incoming call to the counterpart terminal 9 to form a call. That is, when a user of the terminal 1 inputs a voice signal through the handset 5, the codec unit 6 of the terminal 1 signals the voice signal input through the handset 6. Processing is input to the MSM unit 3. In addition, the MSM unit 3 of the terminal 1 wirelessly processes the voice signal input through the codec unit 6 and transmits the voice signal to the counterpart terminal 9 via the base station system unit 8. Is achieved.

In this case, the MSM unit 3 of the terminal 1 stores the call log information for the corresponding call in the memory unit 4, for example, a call start time or a talk time, when the call process ends. . At this time, the base station system unit 8 also stores a call record for the corresponding call when the call of the terminal 1 ends.

On the other hand, when the call (second call) is executed by the user of the terminal 1 again after the first call as described above, the base station system unit 8 stores the current call record (second call). In addition, the call record (first call) stored immediately before the current call is transmitted to the terminal 1. At this time, the MSM unit 3 of the terminal 1 stores the current call record (second call) in the memory unit 4 and the previous call record (first call) received from the base station system unit 8. As shown in FIG. 4, the terminal 1 corresponding to the corresponding call record (first call) is simultaneously displayed on the LCD panel 2.

Accordingly, the user of the terminal 1 can make a call record (first call) of the base station system unit 8 displayed on the LCD panel 2 and the same call record (first call) stored in the terminal 1. If there is no difference after the comparison, it is judged that no piracy was made. However, when the user of the terminal 1 confirms that there is a difference between the call record of the base station system unit 8 and the call record of the terminal 1, that is, it is illegally copied, the user takes appropriate measures.

As described above, according to the present invention, the terminal and the base station simultaneously store the call records currently executed separately, respectively, and then, when a new call is requested, the base station transmits the previous call records to the terminal and compares them with each other in the terminal. By displaying it externally to determine, the user of the actual terminal checks the difference between the base station displayed on the terminal and the call record on the terminal, determines whether the terminal is duplicated, and then takes action based on the result. Has the advantage of significantly improving.

In addition, according to the present invention, since the user can quickly check whether or not the terminal is duplicated without adding a separate complicated circuit configuration, the functionality of the terminal is also significantly improved.
