Abstract

A system of communicating between first and second electronic devices, comprises, in a first device, receiving from a second device, voice representative information acquired by the second device, and connection information indicating characteristics of communication to be used in establishing a communication link with the second device. The system compares the voice representative information with predetermined reference voice representative information and in response to the comparison, establishes a communication link with the second device by using the connection information received from the second device.

First claim

What is claimed is:

1. A method of communicating between first and second electronic devices, comprising:
receiving, by a communication unit, audio information output by the second electronic device including voice representative information acquired by the second electronic device, and connection information indicating a particular one of a plurality of a short range communication types to be used in establishing a communication link with the second electronic device;
comparing by the first electronic device, the voice representative information with predetermined reference voice representative information to detect whether identifying information included in the voice representative information matches an identifier of the first electronic device; and
in response to detecting that the identifying information matches the identifier of the first electronic device, establishing a radio frequency communication link with the second electronic device that output the audio information, using the particular one of the plurality of a short range communication types indicated by the voice representative information.

2. The method of claim 1 , wherein the communication unit comprises a microphone of the first electronic device.

3. The method of claim 2 , wherein the voice representative information and the connection information of the second electronic device are inserted into at least one of an inaudible range and an audible range of the audio information and are broadcast by the second electronic device.

4. The method of claim 1 , wherein the receiving comprises receiving the voice representative information and the connection information of the second electronic device via at least one of, short range communication and mobile communication.

5. The method of claim 1 , wherein the voice representative information comprises at least one of identification (ID) information of the first electronic device, control information for controlling the first electronic device, and control information for controlling the first electronic device and the second electronic device.

6. The method of claim 1 , wherein the receiving of the voice representative information comprises receiving at least one of a data representing raw voice representative information and voice feature information that is extracted from the raw voice representative information.

7. The method of claim 1 , wherein the comparing comprises determining whether a similarity between the voice representative information and the reference voice representative information is equal to or greater than a predetermined value.

8. The method of claim 7 , wherein, when the similarity is equal to or greater than the predetermined value, the establishing comprises establishing the communication link with the second electronic device, based on the connection information of the second electronic device.

9. The method of claim 7 , further comprising, when the similarity is less than the predetermined value, broadcasting the voice representative information received from the second electronic device.

10. The method of claim 1 , wherein the connection information of the second electronic device further comprises at least one of: capability information of the second electronic device, state information of the second electronic device, and service identification information.

11. The method of claim 10 , wherein when the connection information includes the identifying information, and the service identification information indicates searching for a terminal, the method further comprises:
when the identifying information fails to match the identifier of the first electronic device, outputting the audio information by a speaker.

12. The method of claim 1 , wherein the establishing comprises:
transmitting a connection request to the second electronic device; and
receiving an acceptance message in response to the connection request.

13. The method of claim 1 , further comprising:
receiving, from the second electronic device, control information that is extracted from the voice representative information; and
performing a function in response to the control information.

14. The method of claim 13 , wherein the control information comprises at least one of a control command to acquire content, a control command to transmit content, a control command to transmit position information, a control command to synchronize a plurality of pieces of data, a control command to switch a mode, and a control command to perform screen-mirroring.

15. The method of claim 1 , further comprising, switching a screen lock mode of the first electronic device to a screen unlock mode in response to the comparison.

16. A non-transitory computer-readable recording medium having recorded thereon a program for executing the method of claim 1 , by using a computer.

17. The method of claim 1 , wherein:
if the particular one of the plurality of the short range communication types received by the first electronic device from the second electronic device is Near Field Communication (NFC), establishing the radio frequency communication link comprises establishing an NFC communication link with the second electronic device;
if the particular one of the plurality of the short range communication types received by the first electronic device from the second electronic device is Wi-Fi Direct (WFD), establishing the radio frequency communication link comprises establishing a WFD communication link with the second electronic device; and
if the particular one of the plurality of the short range communication types received by the first electronic device from the second electronic device is Bluetooth, establishing the radio frequency communication link comprises establishing Bluetooth communication link with the second electronic device.

18. A method of communicating between first and second electronic devices, comprising:
acquiring, by the second electronic device, voice representative information;
broadcasting, by the second electronic device, the voice representative information and connection information of the second electronic device indicating characteristics of communication to be used in establishing a communication link;
receiving, by the second electronic device, a communication connection request from the first electronic device that receives the broadcast voice representative information and the connection information,
the first electronic device comparing the voice representative information with predetermined reference voice representative information to detect whether identifying information included in the voice representative information matches an identifier of the first electronic device;

establishing, by the second electronic device and the first electronic device, a radio frequency communication link between the first electronic device and the second electronic device, in response to the connection request and utilizing the characteristics of communication,
the first electronic device establishing the radio frequency communication link in response to detecting that the identifying information matches the identifier of the first electronic device; and

transmitting, by the second electronic device, content displayed on the second electronic device to the first electronic device using the radio frequency communication link.

19. The method of claim 18 , wherein the broadcasting comprises periodically broadcasting a sound signal comprising the voice representative information and the connection information of the second electr
