Abstract

A mobile terminal communication method, which includes activating a touch screen of the mobile terminal, entering into an inactive touch screen mode preventing information from being entered on the touch screen of the mobile terminal while a function is executed on the terminal, receiving an input signal through a specified key arranged on the terminal during a time when the inactive touch screen mode is entered, and entering into an active touch screen mode allowing information to be entered on the touch screen in accordance with the received input signal.

Claims

1. A mobile terminal communication method, comprising:

activating a touch screen of the mobile terminal;

entering into an inactive touch screen mode preventing information from being entered on the touch screen of the mobile terminal while a function is executed on the terminal;

receiving an input signal through a specified key arranged on the terminal during a time when the inactive touch screen mode is entered; and

entering into an active touch screen mode allowing information to be entered on the touch screen in accordance with the received input signal.

2. The method of claim 1, wherein the function corresponds to a phone call being connected.

3. The method of claim 1, further comprising:

re-entering the inactivation touch screen mode when information is not input onto the touch screen for a predetermined amount of time after the active touch screen mode has been entered.

4. The method of claim 1, wherein when the active touch screen mode is entered, the method further comprises displaying a keypad on the touch screen and including touch buttons that may be touched to input information.

5. The method of claim 4, wherein the displaying step further displays a display window for displaying information input using the keypad.

6. The method of claim 4, wherein the displaying step further comprises displaying a function button that may be touched to perform a specified function and a call button that may be touched to connect another party to the phone call that is connected.

7. The method of claim 1, wherein when the active touch screen mode is entered, the method further comprises displaying a list of functions that may be touched and selected including at least one of a camera function, a music function, a video function, an electronic-book function and a web-search function.

8. The method of claim 4, wherein the displaying step further displays an input mode selection window including at least one input mode touch button that may be touched to designate an input characteristic of the touch buttons included in the keypad.

9. The method of claim 8, wherein the input characteristics of the touch buttons included in the keypad include at least one of a language input, a character input, a numeral input, and a sign input.

10. The method of claim 8, wherein the at least one touch button in the input mode selection window includes a single button that changes the input characteristics of the touch buttons included in the keypad, said single button changing the input characteristics based on a length of time the single button is touched or a number of times the single button is successively touched.

11. The method of claim 8, wherein the at least one touch button in the input mode selection window includes a plurality of touch mode buttons, each touch mode button corresponding to a different input mode characteristic.

12. The method of claim 1, wherein when the active touch screen mode is entered, the method further comprises displaying a writing input window on the touch screen allowing information to be written on the writing input window.

13. The method of claim 12, wherein the displaying step further displays a display window on the touch screen for displaying the information written on the writing input window.

14. The method of claim 12, wherein the displaying step further comprises displaying a memo function button that may be touched to save the information writing on the writing input window as a memo, and a call button that may be touched to connect another party to a call that is connected.

15. A mobile communication terminal, comprising:

a touch screen;

a first key button; and

a control unit configured to enter into an inactive touch screen mode preventing information from being entered on the touch screen of the mobile terminal while a function is executed on the terminal, to receive an input signal through the first key button during a time when the inactive touch screen mode is entered, and to enter into an active touch screen mode allowing information to be entered on the touch screen in accordance with the received input signal.

16. The mobile communication terminal of claim 15, wherein the function corresponds to a phone call being connected.

17. The mobile communication terminal of claim 15, wherein the control unit re-enters the inactivation touch screen mode when information is not input onto the touch screen for a predetermined amount of time after the active touch screen mode has been entered.

18. The mobile communication terminal of claim 15, wherein when the active touch screen mode is entered, the control unit displays a keypad on the touch screen and including touch buttons that may be touched to input information.

19. The mobile communication terminal of claim 18, wherein the control unit further displays a display window for displaying information input using the keypad.

20. The mobile communication terminal of claim 18, wherein the control unit further displays a function button that may be touched to perform a specified function and a call button that may be touched to connect another party to the phone call that is connected.

21. The mobile communication terminal of claim 15, wherein when the active touch screen mode is entered, the control unit displays a list of functions that may be touched and selected including at least one of a camera function, a music function, a video function, an electronic-book function and a web-search function.

22. The mobile communication terminal of claim 18, wherein the control unit further displays an input mode selection window including at least one input mode touch button that may be touched to designate an input characteristic of the touch buttons included in the keypad.

23. The mobile communication terminal of claim 22, wherein the input characteristics of the touch buttons included in the keypad include at least one of a language input, a character input, a numeral input, and a sign input.

24. The mobile communication terminal of claim 22, wherein the at least one touch button in the input mode selection window includes a single button that changes the input characteristics of the touch buttons included in the keypad, said single button changing the input characteristics based on a length of time the single button is touched or a number of times the single button is successively touched.

25. The mobile communication terminal of claim 22, wherein the at least one touch button in the input mode selection window includes a plurality of touch mode buttons, each touch mode button corresponding to a different input mode characteristic.

26. The mobile communication terminal of claim 15, wherein when the active touch screen mode is entered, the control unit further displays a writing input window on the touch screen allowing information to be written on the writing input window.

27. The mobile communication terminal of claim 26, wherein the control unit further displays a display window on the touch screen for displaying the information written on the writing input window.

28. The mobile communication terminal of claim 26, wherein the control unit further displays a memo function button that may be touched to save the information writing on the writing input window as a memo, and a call button that may be touched to connect another party to a call that is connected.
