Abstract

Provided are methods and apparatuses for performing pairing. A method of performing pairing between a coordinator and a peer device includes: if a second coordinator of a second network relays first pairing information indicating that a first coordinator of a first network is a device to perform pairing, from the first coordinator to a peer device of the second network, disassociating, by the peer device, from the second network, associating with the first network, and then transmitting, to the first coordinator, the first pairing information and second pairing information indicating that the peer device is a peer device to perform pairing.

First claim

What is claimed is:

1. A method of performing pairing between a first device of a first network and a peer device of a second network, the method being performed by the peer device, the method comprising:
receiving first pairing information indicating that the first device is a coordinator of the first network, from the first device through a coordinator of the second network;
determining the first device as the coordinator of the first network based on the first pairing information;
disassociating from the second network;
associating with the first network; and
broadcasting second pairing information indicating that the peer device is a peer device to perform pairing, to the first device.

2. The method of claim 1 , wherein the disassociating from the second network comprises:
transmitting, to the coordinator, a disassociation request to disassociate from the second network; and
receiving a disassociation response that approves the disassociation request from the coordinator.

3. The method of claim 1 , wherein the associating with the first network comprises:
transmitting, to the first device, an association request to associate with the first network; and
receiving an association response that approves the association request from the first device.

4. The method of claim 1 , wherein:
the first pairing information comprises at least one of first Push Button Configuration (PBC) information indicating that a button for instructing to perform pairing has been pushed in the first device, and a media access control (MAC) address of the first device; and
the second pairing information comprises at least one of second PBC information indicating that a button for instructing to perform pairing has been pushed in the peer device, and an MAC address of the peer device.

5. The method of claim 4 , wherein the first pairing information further comprises at least one of an identifier of the first network and coordinator role information indicating that the first device is a coordinator of the first network.

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

7. The method of claim 1 , wherein the second pairing information is broadcasted with the first pairing information to the first device.

8. A method of performing pairing between a first device of a first network and a peer device of a second network, the method being performed by a coordinator of the second network, the method comprising:
relaying, from the first device to the peer device, first pairing information indicating that the first device is a device to perform pairing;
receiving a disassociation request from the peer device; and
transmitting a disassociation response to the peer device,
wherein the peer device is disassociated from the second network and associated with the first network and
wherein the first device is determined as the coordinator of the first network, by the peer device, based on the first pairing information.

9. The method of claim 8 , further comprising:
relaying the first pairing information and second pairing information indicating that the peer device is a peer device to perform pairing from the peer device to the first device.

10. A method of performing pairing between a first device of a first network and a peer device of a second network, the method being performed by the first device, the method comprising:
broadcasting first pairing information indicating that the first device is a coordinator to perform pairing; and
receiving second pairing information indicating that the peer device is a peer device to perform pairing,
wherein the first pairing information is relayed from the first device to the peer device through a coordinator of the second network, and
wherein the peer device is disassociated from the second network and associated with the first network and
wherein the first device is determined as the coordinator of the first network, by the peer device, based on the first pairing information.

11. The method of claim 10 , the method further comprises:
receiving a failure message from the coordinator when the first paring information is not received by the peer device within a predetermined amount of time,
wherein the failure message is relayed from the peer device to the first device via the coordinator.

12. The method of claim 10 , wherein the second pairing information is received with the first pairing information to the first device.

13. A method of performing pairing between a first device of a first network and a peer device of a second network, the method being performed by the first device, the method comprising:
broadcasting first pairing information indicating that the first device is a coordinator of the first network to perform pairing;
receiving the first pairing information, and second pairing information indicating that the peer device is a peer device to perform pairing, from a coordinator of the second network;
transmitting, to the coordinator, an association request to associate with the second network;
receiving an association response that approves the association request from the coordinator; and
associating with the second network,
wherein the first device is determined as the coordinator of the first network, by the peer device, based on the first pairing information.

14. The method of claim 13 , further comprising:
transmitting to a device that belongs to the first network, a handover request to hand over a coordinator role of the first network;
receiving a handover response that approves the handover request from a device that receives the handover request; and
disassociating from the first network.

15. The method of claim 13 , further comprising:
transmitting to a device that belongs to the first network, a movement request to move to the second network; and
receiving a movement response that approves the movement request from a device of the first network that receives the movement request,
wherein the device that receives the movement request is associated with the second network.

16. A peer device of a second network configured to perform pairing, the peer device comprising:
a memory configured to store at least one program; and
a processor,
wherein, when the at least one program is executed by the processor, the peer device is configured to:
receive first pairing information indicating that a first device is a coordinator of the first network, from the first device through a coordinator of a second network, the peer device being associated with the second network;
determining the first device as the coordinator of the first network based on the first pairing information;
disassociate from the second network;
associate with the first network; and
broadcast second pairing information indicating that the peer device is a peer device to perform pairing to the first device.

17. The peer device of claim 16 , wherein, when the at least one program is executed by the processor, the peer device is further configured to:
disassociate from the second network when the peer device transmits, to the coordinator, a disassociation request to disassociate from the second network and receives, from the coordinator, a disassociation response that approves the disassociation request.

18. The peer device of claim 16 , wherein, when the at least one program is executed by the processor, the peer device is further configured to:
disassociate from the second network by:
transmitting, to the coordinator, a disas
