Abstract

The present invention relates to an electronic device and a method of operating the same. The electronic device and the method of operating the electronic device may effectively form a connection between two or more electronic devices by allowing a relaying device to transfer connection information between the electronic devices to a counterpart.

Claims

1. A method of operating a third device to establish a communication link between a first device and a second device, the method comprising:

transmitting a first handover request message to the first device;

receiving a first handover response message from the first device, wherein the first handover response message includes first alternative carrier information comprising first power condition information, and

wherein the first power condition information is related to a first alternative carrier corresponding to the first alternative carrier information;

transmitting a second handover request message to the second device;

receiving a second handover response message from the second device, wherein the second handover response message includes second alternative carrier information comprising second power condition information, and

wherein the second power condition information is related to a second alternative carrier corresponding to the second alternative carrier information; and

transmitting third alternative carrier information to the first device or the second device,

wherein the third alternative carrier information is determined based on at least the first alternative carrier information or the second alternative carrier information.

2. The method of claim 1, wherein each of the first alternative carrier and the second alternative carrier have an inactive status until a specific alternative carrier for the communication link is determined.

3. The method of claim 1,

wherein the first power condition information and the second power condition information include at least active status information, inactive status information, activating status information, or unknown status information.

4. The method of claim 1, wherein the first alternative carrier information sequentially includes information on a plurality of alternative carriers supported by the first device according to priorities.

5. The method of claim 1, wherein the receiving the first handover response message further comprises establishing a first communication link between the first and third devices, wherein the first communication link is different from the communication link.

6. The method of claim 5, wherein the transmitting the third alternative carrier information further comprises transmitting the third alternative carrier information to the first device through the first communication link.

7. The method of claim 1, wherein the transmitting the second handover response message further comprises establishing a second communication link between the second and third devices, wherein the second communication link is different from the communication link.

8. The method of claim 7, wherein the transmitting the third alternative carrier information further comprises transmitting the third alternative carrier information to the second device through the second communication link.

9. The method of claim 1,

wherein each of the first handover response message and the second handover response message includes at least first version information or second version information, and

wherein each of the first version information and the second version information indicates information related to a backward compatibility.

10. The method of claim 1,

wherein each of the first alternative carrier information and the second alternative carrier information includes at least auxiliary data reference count information or an auxiliary data reference,

wherein the auxiliary data reference indicates Near Field Communication (NFC) Data Exchange Format (NDEF) record providing additional information on the first alternative carrier or the second alternative carrier, and

wherein the auxiliary data reference count information includes a number of the auxiliary data references.

11. A third device establishing a communication link between a first device and a second device, wherein the third device comprises:

a receiver that receives a first handover response message from the first device and receives a second handover response message from the second device,

wherein the first handover response message includes first alternative carrier information comprising first power condition information,

wherein the first power condition information is related to a first alternative carrier corresponding to the first alternative carrier information,

wherein the second handover response message includes second alternative carrier information comprising second power condition information, and

wherein the second power condition information is related to a second alternative carrier corresponding to the second alternative carrier information;

a transmitter that transmits a first handover request message to the first device and transmits a second handover request message to the second device, the transmitter further transmitting third alternative carrier information to the first device or the second device; and

a controller that determines the third alternative carrier information based on at least the first alternative carrier information or the second alternative carrier information.

12. The third device of claim 11, wherein each of the first alternative carrier and the second alternative carrier has an inactive status until a specific alternative carrier for the communication link is determined.

13. The third device of claim 11, wherein the first power condition information and the second power condition information include at least active status information, inactive status information, activating status information, or unknown status information.

14. The third device of claim 11, wherein the first alternative carrier information sequentially includes information on a plurality of alternative carriers supported by the first device according to priorities.

15. The third device of claim 11, wherein the controller establishes a first communication link that is different from the communication link.

16. The third device of claim 15, wherein the controller causes the transmitter to transmit the third alternative information to the first device through the first communication link.

17. The third device of claim 11, wherein the controller establishes a second communication link that is different from the communication link.

18. The third device of claim 17, wherein the controller causes the transmitter to transmit the third alternative carrier information to the second device through the second communication link.

19. The third device of claim 11,

wherein each of the first handover response message and the second handover response message includes at least first version information or second version information, and

wherein each of the first version information and the second version information indicates information related to a backward compatibility.

20. The third device of claim 11,

wherein each of the first alternative carrier information and the second alternative carrier information includes at least auxiliary data reference count information or an auxiliary data reference,

wherein the auxiliary data reference indicates Near Field Communication (NFC) Data Exchange Format (NDEF) record providing additional information on the first alternative carrier or the second alternative carrier, and

wherein the auxiliary data reference count information includes a number of the auxiliary data references.
