Abstract

The present invention relates to an electronic device and a method of operating the electronic device. There are provided an electronic device and a method of operating the electronic device that may more effectively resolve handover request collisions by using a specific field value included in a handover request message.

Claims

1. A method performed by an audio device for establishing a communication link between the audio device and an electronic device, comprising:

transmitting to the electronic device an NFC handover request message for establishing communication between the audio device and the electronic device using an alternative carrier for at least one alternative communication link, wherein the NFC handover request message includes a provision for collision resolution information; and

receiving an NFC handover select message from the electronic device, wherein the NFC handover select message includes a provision for power state information.

2. The method of claim 1, wherein the alternative carrier is Bluetooth.

3. The method of claim 1, wherein the alternative carrier is Wi-Fi.

4. The method of claim 1, wherein the handover request message comprises information associated with the alternative carrier supported by the audio device.

5. The method of claim 4, wherein the information associated with the alternative carrier includes a provision for at least one of auxiliary data reference information and auxiliary data reference count information.

6. The method of claim 1, wherein the collision resolution information comprises a number.

7. The method of claim 6, wherein the number is a random number.

8. The method of claim 7, wherein the alternative carrier is Bluetooth.

9. The method of claim 7, wherein the alternative carrier is Wi-Fi.

10. The method of claim 7 further comprising receiving an NFC handover request message from the electronic device, wherein the received NFC handover request message comprises collision resolution information including a random number.

11. An audio device comprising:

an NFC communication module configured to transmit to an electronic device a handover request message for establishing communication between the audio device and the electronic device using an alternative carrier for at least one alternative communication link, wherein the handover request message includes a provision for collision resolution information;

the NFC communication module also configured to receive a handover select message from the electronic device, wherein the handover select message includes a provision for power state information; and

an alternative communication module configured to establish the communication between the first audio device and the electronic device using the alternative carrier.

12. The audio device of claim 11, wherein the alternative carrier is Bluetooth.

13. The audio device of claim 11, wherein the alternative carrier is Wi-Fi.

14. The audio device of claim 11, wherein the handover request message comprises information associated with the alternative carrier supported by the audio device.

15. The audio device of claim 14, wherein the information associated with the alternative carrier includes a provision for at least one of auxiliary data reference information and auxiliary data reference count information.

16. The audio device of claim 11, wherein the collision resolution information comprises a number.

17. The audio device of claim 16, wherein the number is a random number.

18. The audio device of claim 17, wherein the alternative carrier is Bluetooth.

19. The audio device of claim 18, wherein the alternative carrier is Wi-Fi.

20. The audio device of claim 11, wherein each of the handover request message and the handover select message includes a provision for version information.
