Abstract

A method and an apparatus are provided for performing wireless communication between terminals. An inquiry message is transmitted to a neighboring terminal. An inquiry response message is received from the neighboring terminal. It is determined whether the apparatus overlaps the neighboring terminal. When the apparatus overlaps the neighboring terminal, paging is automatically performed, without intervention of a user of the apparatus, and pairing between the apparatus and the neighboring terminal is established.

Claims

1. A method for performing wireless communication between terminals, by a main terminal, the method comprising the steps of:

presenting a screen in a display of the main terminal;

detecting an overlap of a portion of a neighboring terminal and a portion of the main terminal based on a signal which is output from a touch sensor of the neighboring terminal;

in response to detecting the overlap of the portion of the neighboring terminal, automatically paging the neighboring terminal and connecting the neighboring terminal by a wireless communication;

providing, to the neighboring terminal for presenting in a display of the neighboring terminal, a portion of the screen being displayed on the main terminal connected with the neighboring terminal; and

presenting another portion of the screen in the display of the main terminal while the portion of the screen provided from the main terminal is presented in the display of the neighboring terminal.

2. The method as claimed in claim 1, further comprising:

transmitting an inquiry message to the neighboring terminal;

receiving an inquiry response message from the neighboring terminal; and

determining whether the inquiry response message comprises a recognition code indicating that the main terminal overlaps the neighboring terminal,

wherein the main terminal automatically performs the paging with respect to the neighboring terminal when the inquiry response message includes the recognition code.

3. The method as claimed in claim 1, further comprising displaying, to a user, a list of terminals, which are capable of being paired with the main terminal and include the neighboring terminal, when the main terminal does not overlap the neighboring terminal.

4. The method as claimed in claim 1, wherein detecting the overlap of the portion of the neighboring terminal and the portion of the main terminal comprises:

detecting the signal output from the touch sensor of the neighboring terminal; and

determining whether the detected signal has a voltage value greater than or equal to a threshold,

wherein it is determined that the main terminal overlaps the neighboring terminal, when the detected signal has the voltage value greater than or equal to the threshold.

5. The method as claimed in claim 1, wherein the touch sensor of the neighboring terminal operates in an Electromagnetic Resonance (EMR) scheme, and the signal output from the second touch sensor corresponds to a signal in a form of an electromagnetic wave for detecting a position of a pen input.

6. The method as claimed in claim 1, wherein detecting the overlap of the portion of the neighboring terminal and the portion of the main terminal comprises:

detecting a signal emitted from an external pen and the signal output from the touch sensor of the neighboring terminal; and

distinguishing the signal emitted from the external pen and the signal output from the touch sensor of the neighboring terminal.

7. The method as claimed in claim 6, wherein distinguishing the signal emitted from the external pen and the signal output from the touch sensor of the neighboring terminal is performed by at least one filter.

8. The method as claimed in claim 1, further comprising:

determining an overlap direction of the portion of the main terminal and the portion of the neighboring terminal; and

dividing the screen being displayed on the main terminal into the portion of the screen and the another portion of the screen in the determined overlap direction.

9. A non-transitory machine-readable storage medium storing a program, which when executed implements a method for performing wireless communication between terminals by a main terminal, the method comprising the steps of:

presenting a screen in a display of the main terminal;

detecting an overlap of a portion of a neighboring terminal and a portion of the main terminal, based on a signal which is output from a touch sensor of the neighboring terminal;

in response to detecting the overlap of the portion of the neighboring terminal, automatically paging the neighboring terminal and connecting the neighboring terminal by a wireless communication;

providing, to the neighboring terminal for presenting in a display of the neighboring terminal, a portion of the screen being displayed on the main terminal connected with the neighboring terminal; and

presenting another portion of the screen in the display of the main terminal while the portion of the screen provided from the main terminal is presented in the display of the neighboring terminal.

10. The non-transitory machine-readable storage medium as claimed in claim 9, wherein the method further comprises:

determining an overlap direction of the portion of the main terminal and the portion of the neighboring terminal; and

dividing the screen being displayed on the main terminal into the portion of the screen and the another portion of the screen in the determined overlap direction.

11. An apparatus for performing wireless communication between terminals, the apparatus comprising:

a communication unit;

a touch screen for displaying images and sensing an input on the touch screen;

a controller for;

presenting a screen on the touch screen;

detecting an overlap of a portion of a neighboring terminal and a portion of the main terminal, based on a signal which is output from a touch sensor of the neighboring terminal; and

in response to detecting the overlap of the portion of the neighboring terminal, automatically paging the neighboring terminal and connecting the neighboring terminal by a wireless communication;

providing, to the neighboring terminal for presenting in a display of the neighboring terminal, a portion of the screen being displayed on the main terminal connected with the neighboring terminal; and

presenting another portion of the screen in the display of the main terminal while the portion of the screen provided from the main terminal is presented in the display of the neighboring terminal.

12. The apparatus as claimed in claim 11, wherein the controller is configured to:

transmit an inquiry message to the neighboring terminal;

receive an inquiry response message from the neighboring terminal;

determine whether the inquiry response message comprises a recognition code indicating that the apparatus overlaps the neighboring terminal; and

automatically performs the paging with respect to the neighboring terminal when the inquiry response message includes the recognition code.

13. The apparatus as claimed in claim 11, wherein the controller controls the touch screen to display, to a user, a list of terminals, which are capable of being paired with the apparatus and include the neighboring terminal, when the apparatus does not overlap the neighboring terminal.

14. The apparatus as claimed in claim 11, wherein the controller is configured to:

detect the signal output from the touch sensor of the neighboring terminal;

determine whether the detected signal has a voltage value greater than or equal to a threshold; and

determine that the apparatus overlaps the neighboring terminal, when the detected signal has the voltage value greater than or equal to the threshold.

15. The apparatus as claimed in claim 11, wherein the touch sensor of the neighboring terminal operates in an Electromagnetic Resonance (EMR) scheme, and the signal output from the second touch sensor corresponds to a signal in a form of an electromagnetic wave for detecting a position of a pen input.

16. The apparatus as claimed in claim 11, further comprising at least one filter for distinguishing a signal emitted from an external pen and the signal output from the touch sensor of the neighboring terminal.

17. The apparatus as claimed in claim 11, wherein the controller is configured to:
