Abstract

A method and an electronic device for establishing, at a first electronic device, a communication link between the first electronic device and at least one other electronic device in a Near Field Communication (NFC) network are provided. The method includes setting up an underlying Media Access Control (MAC) link; sending a Parameter Exchange (PAX) command for exchanging parameters concerning a Logical Link Control Protocol (LLCP) to at least one other electronic device; receiving a response PAX command for exchanging parameters concerning the LLCP from at least one other electronic device; and establishing the communication link between the first electronic device and the at least one other electronic device based on the received response PAX command.

Claims

1. A method for establishing, at a first electronic device, a communication link between the first electronic device and at least one other electronic device in a Near Field Communication (NFC) network, the method comprising:

sending, to the at least one other electronic device, after setting up an underlying Media Access Control (MAC) link between the first electronic device and the at least one other electronic device, a Parameter Exchange (PAX) command for exchanging parameters concerning a Logical Link Control Protocol (LLCP) link to be established with the at least one other electronic device;

receiving, from the at least one other electronic device, in response to the PAX command, a response PAX command for exchanging parameters concerning the LLCP link; and

establishing the LLCP link between the first electronic device and the at least one other electronic device based on the response PAX command,

wherein the PAX command comprises a parameter list of at least one service registered in the first electronic device.

2. The method of claim 1, wherein the PAX command comprises a service discovery request for returning a parameter list of at least one service registered in the at least one other electronic device.

3. The method of claim 2, wherein the PAX command comprises at least one of a type of service, a length of parameter information, a parameter type identifier, a parameter negotiation field, a service discovery operation identifier, and an announcement operation identifier.

4. The method of claim 2, wherein the response PAX command comprises the parameter list of the at least one service registered in the at least one other electronic device.

5. The method of claim 4, wherein the response PAX command comprises at least one of a type of service, a length of parameter information, a parameter type identifier, a parameter negotiation field, a service discovery operation identifier, and an announcement operation identifier.

6. The method of claim 1, wherein establishing the LLCP link comprises:

matching a parameter list of at least one service registered in the at least one other electronic device and the parameter list of the at least one service registered in the first electronic device; and

setting up a communication channel based on the matching result.

7. An electronic device for establishing a communication link between the electronic device and at least one other electronic device in a Near Field Communication (NFC) network, the device comprising:

a transceiver for sending, after setting up an underlying Media Access Control (MAC) link between the electronic device and the at least one other electronic device, a Parameter Exchange (PAX) command for exchanging parameters concerning a Logical Link Control Protocol (LLCP) link to be established between the electronic device and the at least one other electronic device, and receiving, from the at least one other electronic device, in response to the PAX command, a response PAX command for exchanging parameters concerning the LLCP link; and

a processor for controlling the transceiver to establish the LLCP link between the electronic device and the at least one other electronic device based on the response PAX command,

wherein the PAX command comprises a parameter list of at least one service registered in the electronic device.

8. The device of claim 7, wherein the PAX command comprises a service discovery request for returning a parameter list of at least one service registered in the at least one other electronic device.

9. The device of claim 8, wherein the PAX command comprises at least one of a type of service, a length of parameter information, a parameter type identifier, a parameter negotiation field, a service discovery operation identifier, and an announcement operation identifier.

10. The device of claim 8, wherein the response PAX command comprises the parameter list of the at least one service registered in the at least one other electronic device.

11. The device of claim 10, wherein the response PAX command comprises at least one of a type of service, a length of parameter information, a parameter type identifier, a parameter negotiation field, a service discovery operation identifier, and an announcement operation identifier.

12. The device of claim 7, wherein the processor matches a parameter list of at least one service registered in the at least one other electronic device and the parameter list of the at least one service registered in the electronic device and controls the transceiver to set up a communication channel based on the matching result.

13. A method for establishing, at a first electronic device, a communication link between the first electronic device and at least one other electronic device in a Near Field Communication (NFC) network, the method comprising:

receiving, from the at least one other electronic device, after setting up an underlying Media Access Control (MAC) link between the electronic device and the at least one other electronic device, a Parameter Exchange (PAX) command for exchanging parameters concerning a Logical Link Control Protocol (LLCP) link to be established between the electronic device and the at least one other electronic device;

sending, to the at least one other electronic device, in response to the received PAX command, a response PAX command for exchanging parameters concerning the LLCP link; and

establishing the communication LLCP link between the first electronic device and the at least one other electronic device,

wherein the PAX command comprises a parameter list of at least one service registered in the at least one other electronic device.

14. The method of claim 13, wherein the PAX command comprises a service discovery request for returning a parameter list of at least one service registered in the first electronic device.

15. The method of claim 14, wherein the PAX command comprises at least one of a type of service, a length of parameter information, a parameter type identifier, a parameter negotiation field, a service discovery operation identifier, and an announcement operation identifier.

16. The method of claim 14, wherein the response PAX command comprises the parameter list of the at least one service registered in the first electronic device.

17. The method of claim 16, wherein the response PAX command comprises at least one of a type of service, a length of parameter information, a parameter type identifier, a parameter negotiation field, a service discovery operation identifier, and an announcement operation identifier.

18. An electronic device for establishing a communication link between the electronic device and at least one other electronic device in a Near Field Communication (NFC) network, the device comprising:

a transceiver for receiving, from the at least one other electronic device, after setting up an underlying Media Access Control (MAC) link between the electronic device and the at least one other electronic device, a Parameter Exchange (PAX) command for exchanging parameters concerning a Logical Link Control Protocol (LLCP) link to be established between the electronic device and the at least one other electronic device, and sending, to the at least one other electronic device, in response to the received PAX command, a response PAX command for exchanging parameters concerning the LLCP link; and
