Description

The method for Automatically locking of Mobile Phone's Keypad}

The present invention relates to a method of automatically locking a keypad of a wireless terminal and a computer-readable recording medium recording a program for realizing the method. More particularly, after a preset time has elapsed after a call, The present invention relates to a method for automatically locking a keypad of a wireless terminal for preventing unwanted calls by operating a locking function and a computer-readable recording medium having recorded thereon a program for realizing the method.

Because of the advantages of wireless handsets, users of early wireless handsets can make mobile calls anytime, anywhere, only paying attention to the quality of service but indifferent to call charges.

However, over time, interest in call charges began to grow as the dominance of the idea that such advantages were not new.

Most users carry their wireless devices in pockets or bags. Because of this, when you are seated on the move or in a chair, you frequently press the keypad button of the wireless terminal without knowing it. Such a call does not talk to the real party and the call charge is continuously added. If a wireless terminal has a speed dial function, the problem is even worse because a call can be made by pressing only one of the keypad buttons.

In general, a method of locking a keypad in a wireless terminal sets a keypad lock function by a user directly pressing a lock function key. After that, when the user wants to call, the user enters a password to log in and then makes a call. Thereafter, when the call is over, the user needs to press the lock function key again.

The present invention has been proposed to solve the above problems, and after the call of the wireless terminal is terminated, set a time limit for receiving a signal for re-call from the keypad to automatically set the time limit after the wireless terminal It is an object of the present invention to provide a method of automatically locking a keypad of a wireless terminal for preventing a call in advance by not receiving a signal from a keypad of the keypad and a computer-readable recording medium recording a program for realizing the method.

The method of the present invention for achieving the above object, the automatic locking method of the keypad of the wireless terminal, the first step of confirming the end of the call; A second step of confirming the automatic lock function setting of the wireless terminal and operating a timer when the call is terminated; A third step of determining that there is no new key input signal during the timer operation; And a fourth step of activating the lock function of the keypad as the set time of the timer is completed without a new key input signal.

On the other hand, the present invention, a wireless terminal having a processor, the first function for confirming the end of the call; A second function of operating a timer by checking an automatic lock function setting of the wireless terminal as the call is confirmed; A third function of determining that there is no new key input signal during the timer operation; And a computer-readable recording medium having recorded thereon a program for realizing a fourth function of activating the lock function of the keypad as the set time of the timer is completed without a new key input signal.

As such, the present invention can automatically lock the function after a certain time even if you do not press the lock (Lock) button to reduce the number of accidentally connected calls.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a configuration diagram of an embodiment of a wireless terminal to which the present invention is applied.

As shown in FIG. 1, a wireless terminal to which the present invention is applied is configured to transmit a signal received from a transmitter 13 to a base station through an antenna or to transmit a signal received from the base station through an antenna to the receiver 12. The duplexer 11, the receiving unit 12 for receiving the signal received by the duplexer 11 under the control of the control unit 18, and the audio unit 14 under the control of the control unit 18 through the interface unit 17. The control unit 18 is controlled by the control unit 18 through the transmission unit 13 and the interface unit 17 for transmitting the modulated signal to the duplexer 11, and modulates the voice signal input through the microphone into a digital signal, the receiving unit 12 Audio unit 14 for demodulating the digital signal received through the E-mail signal and outputting the ring signal generated from the base station through the speaker. In particular, a key input unit 15 for inputting an automatic lock time, a display unit 16 for displaying the input lock time information when the lock time is input, and an input / output between the control unit 18 and peripheral components The interface unit 17 for interfacing the data, the overall operation of the wireless terminal to control, in particular, the controller 18 for checking the time of the timer, the ROM 19 for storing the program for controlling the overall operation of the wireless terminal And a RAM 20 for storing input / output data and various data processed when the wireless terminal operates, and a timer 21 for counting an automatic lock time.

2 is a flowchart illustrating an embodiment of an automatic locking method of a keypad of a wireless terminal according to the present invention.

First, the controller 18 of the wireless terminal checks whether the call has ended (201), and as a result of the check, waits for termination if the call has not ended, and determines whether the automatic lock function is set if the call has ended (202). . As a result of the determination, the automatic lock function is terminated if it is not set, and if it is set, the timer is operated according to the set time (203).

Thereafter, it is determined whether a new key input signal has been received during the timer operation (204). As a result of determination 204, if a new key input signal is received, the timer 21 is reset (206), and then the process proceeds to step 201. On the other hand, if a new key input signal is not received, the operation of the timer 21 currently being operated is maintained (205).

Thereafter, it is determined whether the set time of the timer 21 is completed (207). If it is not completed, the process proceeds to step 204. If it is completed, the lock function of the keypad is activated (208).

As described above, the method of the present invention may be implemented as a program and stored in a recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.) in a computer-readable form. Since this process can be easily implemented by those skilled in the art will not be described in more detail.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.

The present invention as described above, after the call is terminated, the keypad is automatically locked after a certain time through the automatic lock function of the keypad of the wireless terminal, so that unwanted calls are not connected by an accidentally pressed key input. In addition to the effect, there is an effect that makes it easier for others to use when the wireless terminal is lost.
