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:

transmitting an inquiry message to a neighboring terminal;

receiving an inquiry response message from the neighboring terminal;

determining whether the main terminal overlaps the neighboring terminal; and

when the main terminal overlaps the neighboring terminal, automatically performing paging with respect to the neighboring terminal and establishing pairing between the main terminal and the neighboring terminal.

2. The method as claimed in claim 1, further comprising 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 the 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 determining whether the main terminal overlaps the neighboring terminal comprises:

detecting a signal output from a 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 4, wherein the touch sensor operates in an Electromagnetic Resonance (EMR) scheme, and the signal output from the 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 5, wherein determining whether the main terminal overlaps the neighboring terminal further comprises outputting a signal emitted from an external pen and the signal output from the touch sensor of the neighboring terminal, in such a manner as to distinguish the signal emitted from the external pen and the signal output from the touch sensor of the neighboring terminal, from a signal in a form of an electromagnetic wave received from an outside.

7. The method as claimed in claim 6, wherein outputting 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:

generating first screen data to be displayed by the main terminal and second screen data to be displayed by the neighboring terminal; and

transmitting the second screen data to the neighboring terminal.

9. The method as claimed in claim 8, wherein the first screen data and the second screen data represent images, into which an image corresponding to one application window is divided.

10. The method as claimed in claim 8, wherein the first screen data and the second screen data are generated based on a position of the overlap of the main terminal and the neighboring terminal.

11. A non-transitory machine-readable storage medium for performing wireless communication between terminals and storing a program, which when executed implements the steps of:

transmitting an inquiry message to a neighboring terminal;

receiving an inquiry response message from the neighboring terminal;

determining whether the main terminal overlaps the neighboring terminal; and

when the main terminal overlaps the neighboring terminal, automatically performing paging with respect to the neighboring terminal and establishing pairing between the main terminal and the neighboring terminal.

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

a communication unit for transmitting an inquiry message to a neighboring terminal, and receiving an inquiry response message from the neighboring terminal;

a controller for determining whether the apparatus overlaps the neighboring terminal, and when the apparatus overlaps the neighboring terminal, automatically performing paging with respect to the neighboring terminal and establishing pairing between the apparatus and the neighboring terminal.

13. The apparatus as claimed in claim 12, wherein the controller determines whether the inquiry response message comprises a recognition code indicating that the apparatus overlaps the neighboring terminal, and

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

14. The apparatus as claimed in claim 12, wherein the controller controls a display unit to display, to the 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.

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

detect a signal output from a 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.

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

17. The apparatus as claimed in claim 16, further comprising at least one filter for outputting a signal emitted from an external pen and the signal output from the touch sensor of the neighboring terminal, in such a manner as to distinguish the signal emitted from the external pen and the signal output from the touch sensor of the neighboring terminal, from a signal in a form of an electromagnetic wave received from an outside.

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

generate first screen data to be displayed by the apparatus and second screen data to be displayed by the neighboring terminal; and

transmit the second screen data to the neighboring terminal.

19. The apparatus as claimed in claim 18, wherein the first screen data and the second screen data represent images, into which an image corresponding to one application window is divided.

20. The apparatus as claimed in claim 18, wherein the first screen data and the second screen data are generated based on a position of the overlap of the apparatus and the neighboring terminal.
