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 power condition information related to a first alternative carrier, and first connection information for the first alternative carrier;

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 power condition information related to a second alternative carrier, and second connection information for the second alternative carrier; and

transmitting a third handover response message containing alternative carrier information to the first device or the second device,

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

2. The method of claim 1,

wherein each of the first handover response message and the second handover response message includes at least one of 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.

3. The method of claim 1,

wherein the first alternative carrier and the second alternative carrier have an inactive status until a specific alternative carrier for the communication link is determined.

4. The method of claim 1,

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

5. The method of claim 1,

wherein each of the first handover response message and the second handover response message includes at least one of auxiliary data reference count information or an auxiliary data reference,

wherein the auxiliary data reference indicates NDEF (NFC Data Exchange Format) 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 reference.

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

7. The method of claim 1, wherein each of the first handover request message, the first handover response message, the second handover request message and the second handover response message includes flags indicating a beginning and an ending of a message.

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

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

wherein the first handover response message includes first power condition information related to a first alternative carrier and first connection information for the first alternative carrier, and

wherein the second handover response message includes second power condition information related to a second alternative carrier and second connection information for the second alternative carrier;

a transmitter that transmits a first handover request message to the first device and a second handover request message to the second device,

wherein the transmitter transmits a third handover response message containing alternative carrier information to the first device or the second device; and

a controller that determines the alternative carrier information,

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

9. The third device of claim 8, wherein each of the first identification information and the second identification information includes at least one of an alternative carrier type format, an alternative carrier type length, an alternative carrier type, or alternative carrier data.

10. The third device of claim 8, wherein each of the first handover response message and the second handover response message includes at least one of 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.

11. The third device of claim 8, wherein the first alternative carrier and the second alternative carrier have an inactive status until a specific alternative carrier for the communication link is determined.

12. The third device of claim 8, wherein the first power condition information and the second power condition information includes at least one of active status information, inactive status information, activating status information or unknown status information.

13. The third device of claim 8,

wherein each of the first handover response message and the second handover response message includes at least one of auxiliary data reference count information or an auxiliary data reference,

wherein the auxiliary data reference indicates NDEF (NFC Data Exchange Format) 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 reference.

14. The third device of claim 8, wherein each of the first handover request message, the first handover response message, the second handover request message and the second handover response message includes flags indicating a beginning and an ending of a message.
