Abstract

A wireless communication method, and a wireless communication apparatus and wireless communication system using the same. The wireless communication method includes pairing with a specific device, extracting a media access control (MAC) address of the specific device, and communicating with the specific device. Accordingly, even when a MAC address of a counterpart device is not known, pairing with the counterpart device can be performed without interference with other devices.

Claims

1. A wireless communication method of a device, the method comprising:

pairing the device with a counterpart device by transmitting a unique address of the device to the counterpart device using a shared address and by receiving a unique address of the counterpart device from the counterpart device; and

communicating with the counterpart device using at least one of the unique address of the device and the unique address of the counterpart device.

2. The method according to claim 1, wherein the pairing comprises:

transmitting a request for pairing to the counterpart device; and

receiving approval for pairing from the counterpart device.

3. The method according to claim 2, wherein in the transmitting the request, pairing with the counterpart device is requested by wirelessly transmitting a message including a password to the counterpart device using the shared address.

4. The method according to claim 1, wherein the pairing comprises:

receiving a request for pairing from the counterpart device; and

transmitting approval for pairing to the counterpart device.

5. The method according to claim 4, wherein in the transmitting approval, pairing with the counterpart device is approved by wirelessly transmitting a message including a password to the counterpart device using the shared address.

6. The method according to claim 1, wherein in the pairing, the device is paired with the counterpart device by setting a first shared address selected from a plurality of shared addresses to be an address for transmission and setting a second shared address selected from the plurality of shared addresses to be an address for reception.

7. The method according to claim 1, wherein in the pairing, the device is paired with a plurality of counterpart devices by receiving unique addresses of the plurality of counterpart devices.

8. The method according to claim 1, wherein in the pairing, if pairing is initially performed, the device is paired with the counterpart device by wirelessly transmitting a message including a password input by a user to the counterpart device.

9. The method according to claim 1, wherein in the pairing, if pairing is not initially performed, the device is paired with the counterpart device by wirelessly transmitting a message including a pre-stored password to the counterpart device.

10. A wireless communication apparatus, comprising:

a storage unit which stores a shared address;

a transmission/reception unit which pairs with a counterpart device by transmitting a unique address of the wireless communication apparatus to the counterpart device using a shared address and by receiving a unique address of the counterpart device from the counterpart device; and

a control unit which communicates with the counterpart device using at least one of the unique address of the wireless communication apparatus and the unique address of the counterpart device.

11. The wireless communication apparatus according to claim 10, wherein the transmission/reception unit transmits a request for pairing to the counterpart device, and receives approval for pairing from the counterpart device.

12. The wireless communication apparatus according to claim 11, wherein the transmission/reception unit requests pairing with the counterpart device by wirelessly transmitting a message including a password to the counterpart device using the shared address.

13. The wireless communication apparatus according to claim 10, wherein the transmission/reception unit receives a request for pairing from the counterpart device, and transmits approval for pairing to the counterpart device.

14. The wireless communication apparatus according to claim 13, wherein the transmission/reception unit approves pairing with the counterpart device by wirelessly transmitting a message including a password to the counterpart device using the shared address.

15. The wireless communication apparatus according to claim 10, wherein the transmission/reception unit is paired with the counterpart device by setting a first shared address selected from a plurality of shared addresses to be an address for transmission and setting a second shared selected from the plurality of shared addresses to be an address for reception.

16. The wireless communication apparatus according to claim 10, wherein the transmission/reception unit is paired with plurality of counterpart devices by receiving unique addresses of the plurality of counterpart devices.

17. The wireless communication apparatus according to claim 10, wherein if pairing is initially performed, the transmission/reception unit is paired with the counterpart device by wirelessly transmitting a message including a password input by a user to the counterpart device.

18. The wireless communication apparatus according to claim 10, if pairing is not initially performed, the transmission/reception unit is paired with the counterpart device by wirelessly transmitting a message including a pre-stored password to the counterpart device.

19. A wireless communication system, comprising:

a first device which transmits pairing request data, including a password, using a shared address; and

a second device which receives the transmitted pairing request data, and if the password of the received pairing request data is the same as a stored password, transmits pairing approval data including the password using the shared address.

20. A wireless communication system, comprising:

a first device which wirelessly transmits pairing request data and first pairing data, using a shared address; and

a second device which wirelessly transmits pairing approval data and second pairing data, using the shared address, based on information included in the pairing request data and the first pairing data.

21. A wireless communication system, comprising:

a first device which performs pairing by wirelessly transmitting data, including a password and a first media access control (MAC) address, using a shared address; and

a second device which performs pairing by wirelessly transmitting data including the password and a second MAC address, using the shared address.
