Due to this mobility, the number of wireless communication subscribers has increased exponentially, and in recent years, wireless communication terminals are widely used by the general public.

A general wireless communication terminal has a function of "locking" in order to prevent damage caused by unauthorized use of another person (toll charge). In other words, the lock setting means that a predetermined number of passwords (for example, four digits) are set in advance for menus such as call origination, message inbox confirmation, and wireless Internet access. It is a function that can be used normally only when a password is entered and matched.

However, after the user locks, such a user often loses a password set by himself, and thus, functions such as call origination, message receipt check, and wireless Internet access may not be properly used. Conventionally, in order to solve this problem, a password of an administrator level that can release all lock settings apart from a password set by a user has been stored in a wireless communication terminal.

However, since the password of the administrator level is the same for all wireless communication terminals of the same type, there is a problem in that anyone can unlock the wireless communication terminal lock setting if only one password is known. As a result, even if the wireless communication terminal is lost when the lock is set, there is a problem in that it is not possible to effectively prevent damage caused by unauthorized use of other persons (call charge).

The present invention has been proposed to solve the above problems, the administrator-level password for releasing the lock setting set by the user in the wireless communication terminal to the unique number (IMEI) and time information of the wireless communication terminal It is an object of the present invention to provide a wireless communication terminal and a method having a password generation function for unlocking to effectively prevent unauthorized use of other people and to enhance security.

As shown in FIG. 1, the wireless communication terminal having a password generation function for unlocking according to the present invention includes a wireless transmission / reception apparatus 11, a central processing unit (MSM) 12, and a codec 13. , A storage device 14, a voice output device (speaker) 15, a display device (LCD) 16, an input device (keypad) 17, and a voice input device (microphone) 18.

The radio transceiver 11 wirelessly transmits and receives a signal with a base station through an antenna.

The central processing unit (MSM) 12 drives and controls the wireless communication terminal and, in particular, uses a unique number (IMEI: International Mobile station Equipment Identity) and time information of the wireless communication terminal to unlock the password. Create At this time, the password generated by the central processing unit (MSM) (12) is generated separately from the lock password set by the user, the administrator level that can be unlocked in the case of losing the lock password previously set by the user The same purpose as the password.

Conventional administrator-level passwords are the same for all wireless communication terminals of the same type, and were stored in advance when the wireless communication terminal is released. In contrast, the wireless communication terminal according to the present invention generates an administrator-level password in real time using its own unique number (IMEI) and time information. At this time, the unique ID (IMEI) of the wireless communication terminal is a 15-digit unique number embedded in the wireless communication terminal. Therefore, a general user who does not know the unique number (IMEI) of the wireless communication terminal does not release the lock setting.

Referring to FIG. 2, the CPU 12 generates a password for unlocking using a unique number (IMEI) and time information of the wireless communication terminal.

1) Add the top 1 digit and the top 2 digits of the unique number (IMEI).

2) The added value is the remainder operation (%, modula 10).

3) The result of the remaining operation and the time of 12 hour format are "OR" operation.

4) The result of the "OR" operation is the remainder operation (%, modula 10).

5) The result of the remaining operation is determined as the first digit of the password.

The same is true for the top 3 digits and top 4 digits, the top 5 digits and top 6 digits, and the top 7 digits and top 8 numbers. By performing the process, the second digits, the third digits, and the fourth digits of the password are generated, respectively, to generate a total of four digit administrator level passwords. At this time, each number and time is 4 bits, and the time uses the "hour" value among "hour", "minute", and "second".

 Hereinafter, a process of generating an administrator-level password will be described in more detail with an example where the unique number (IMEI) of the wireless communication terminal is "353591000652512" and the current time is 3:00.

1) Add the top 1 digit and the top 2 digits of the unique number (IMEI).

3 + 5 = 8

2) The added value is the remainder operation (%, modula 10).

8% 10 = 8

3) The result of the remaining operation and the time of 12 hour format are "OR" operation.

1000 (8 binary representation) | 0011 (3 binary representation)

     = 1011 = 11 (in decimal)

4) The result of the "OR" operation is the remainder operation (%, modula 10).

11% 10 = 1

5) The result of the remaining operation is determined as the first digit of the password.

1st digit of admin level password = 1

In this way, the second, third, and fourth digits are 1, 3, and 3. Therefore, the final administrator level password is "1133".

That is, the central processing unit (MSM) 12 outputs a screen through which the password can be input according to the lock release request signal received through the input device (keypad) 17 through the display device (LCD) 16. A password is input through the input device (keypad) 17. Then, it is checked whether or not the input password matches a user password previously stored in the storage device 14, and if it matches, the lock is released to use the corresponding menu (function).

On the other hand, if the received password does not match the user password previously stored in the storage device 14 generates a manager level password in real time using the unique number (IMEI) and time information of the wireless communication terminal. In addition, if the generated administrator-level password and the input password is compared and matched, the lock is released to enable the corresponding menu (function). Maintain to block the use of the menu (function). At this time, the administrator-level password can be generated using a program installed in a computer (PC) in a service center or the like. As such, each wireless communication terminal generates a different password in real time so that no one can unlock it.

On the other hand, the codec 13 converts the signal received from the wireless transmitting and receiving device 11 into voice under the control of the central processing unit 12 and outputs it to the voice output device (speaker) 15. The voice input from the voice input device (microphone) 18 is converted into a signal and transmitted to the central processing unit 12 so as to be transmitted through the wireless transmitting and receiving device 11.

The storage device 14 stores a program and a file system (image, character, icon) for driving the wireless communication terminal, an unlock password set by the user, and a unique number (IMEI) of the wireless communication terminal. have.

The voice output device (speaker) 15 outputs the voice received from the codec (13), and the voice input device (microphone) 18 receives the voice and the codec (13) To pass.

The display device (LCD) 16 outputs a screen (including a password input screen) according to the control of the CPU 12.

The input device (keypad) 17 receives a telephone number, a menu selection signal, a password, and an unlock request signal through a button.

The overall operation of the present invention will be described in more detail with reference to FIG. 3.
