2 is a flowchart illustrating a process of releasing lock and executing a quick function in a mobile terminal according to a first embodiment of the present invention.

Reference is made to FIG. 2, which is shown in steps 201 to 205 of the unlocking and quick function execution processing in the portable terminal according to an embodiment of the present invention. In step 201, which is a locked state in which the input of the key button of the portable terminal is restricted, the controller 110 determines that the lock / release key button is input. Proceeding to step 201, the locked state of the mobile terminal is maintained. However, when the lock / unlock key button is input, the controller 110 determines whether a predetermined key button is input except for the locked / unlock key button in step 203. When a predetermined key button other than the locked / release key button is input in step (203), the controller 110 releases the lock of the portable terminal and performs a specific function corresponding to the input key button (204). Proceed to step). For example, when the lock / release key button is input and a menu key button for displaying a menu of the portable terminal is input within a predetermined time, a menu screen is displayed on the portable terminal simultaneously with unlocking of the portable terminal.

In addition, if a predetermined key button other than the locked / release key button is not input within a predetermined time in step (203), the controller 110 releases only the locked function of the portable terminal.

3 is a flowchart illustrating a process for unlocking and executing a quick function through fingerprint recognition in a mobile terminal according to a second embodiment of the present invention.

Referring to FIG. 3, in the mobile terminal according to the second embodiment of the present invention, the unlocking and quick function execution processing through fingerprint recognition are shown in steps 301 to 311. In step 301, which is a locked state in which the input of the key button is restricted, the controller 110 receives the fingerprint in step 302 when the lock / release key button having the fingerprint pad on the upper side is input. Judge perception. In step 302, if there is no input of the lock / release key button having the fingerprint recognition unit 170 above and a fingerprint input, the controller 110 proceeds to step 301 to lock the mobile terminal. Maintain state. The controller 110 determines whether a predetermined key button other than the locked / release key button is input within a predetermined time after the input of the lock / release key button and the fingerprint. If a predetermined key button other than the locked / release key button is input within a predetermined time, the control unit 110 detects this in step 303 and controls the authentication unit 130 to proceed to step 304. do. In step 304, the authenticator 130 compares and determines whether the authenticated fingerprint of the user stored in the memory 140 matches the input fingerprint. If the user's authenticated fingerprint stored in the memory 140 and the input fingerprint coincide with each other according to the determination result in the step 304, the controller 110 releases the lock of the mobile terminal and simultaneously enters the input key button. The operation proceeds to step 306 by performing the corresponding specific function.

However, if it does not match in step 305, the controller 110 cancels input of a predetermined key button except for the locked / release key button in step 307, and returns to step 301.

If a predetermined key button other than the locked / release key button is not input within a predetermined time in step 303, the controller 130 detects this and controls the authentication unit 130 to proceed to step 308. do. In operation 308, the fingerprint of the user stored in the memory 140 and the input fingerprint are compared with each other to determine whether the input fingerprint matches. The controller 110 releases the lock of the portable terminal when the authenticated fingerprint of the user stored in the memory 140 and the input fingerprint match according to the determination result in step 308. Proceed to step) to maintain the locked state of the mobile terminal.

In another embodiment of the present invention, if a predetermined key button other than the locked / release key button is a numeric key button, if the numeric key button is input for a predetermined time or more, the controller 110 returns to the telephone number specified by the input number. I can send it.

Accordingly, when a user simultaneously inputs a lock / release key button and a function key button or a lock / release key button and a numeric key button, the controller 110 releases the locked state and accesses a desired menu or switches to a desired mode. In addition, when the fingerprint recognition pad is mounted on the lock / release key button, the control unit 110 may perform security authentication when the user simultaneously inputs the lock / release key button and the function key button or the lock / release key button and the numeric key button. To unlock and access the desired menu or switch to the desired mode.

Meanwhile, in the above description of the present invention, specific embodiments have been described, but various modifications may be made within the scope of the present invention. In particular, the present invention is an example of a mobile terminal having a lock / release key button, but if there is a device that functions as a lock / release key button without having a separate lock / release button, the present invention can be applied. have. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined by the equivalents of the claims and claims.

As described above, since the present invention performs the unlocking step and the user's desired function execution step at the same time, it is possible to execute the desired function faster than when each step is performed in order. In addition, according to an embodiment of the present invention, if the fingerprint pad is mounted on the upper side of the lock / release key button, the user can perform the authentication step through the fingerprint recognition, the unlocking step, and the step of executing the desired function at the same time. Can be used conveniently.
