Abstract

Disclosed are a method and a system for Bluetooth communication. In the Bluetooth system, a Bluetooth device includes: a Radio Frequency Identification (RFID) reader for reading out RFID information from the RFID Tag within an effective transmission and receiving range and outputting the RFID information; a control unit for activating the RFID reader when a request for Bluetooth connection using the RFID is inputted by a user in a Bluetooth communication mode, extracting the bonding information from the RFID information inputted from the RFID reader, and outputting the bonding information; and a Bluetooth module for receiving the bonding information outputted from the control unit, pairing the first Bluetooth device using the bonding information, and performing Bluetooth communication.

Claims

1. A Bluetooth system comprising:

a first Bluetooth device having a Raido Frequency Identification (RFID) Tag that stores bonding information of the device; and

a second Bluetooth device for detecting a i request for Bluetooth connection using an RFID, reading RFID information from the RFID tag, extracting the bonding information from the RFID information to pair the first Bluetooth device, pairing the first Bluetooth device using the bonding information and performing Bluetooth communication.

2. The Bluetooth system according to claim 1, wherein the second Bluetooth device comprises:

an RFID reader for reading out RFID information from the RFID tag within an effective transmission and receiving range and outputting the RFID information;

a control unit for activating the RFID reader when a request for Bluetooth connection using the RFID is inputted by a user in a Bluetooth communication mode, extracting the bonding information from the RFID information inputted from the RFID reader, and outputting the bonding information; and

a Bluetooth module for receiving the bonding information outputted from the control unit, pairing the first Bluetooth device using the bonding information, and performing Bluetooth communication.

3. The Bluetooth system according to claim 2, wherein the second Bluetooth device further comprises an RFID Tag that stores bonding information thereof.

4. The Bluetooth system according to claim 4, wherein the bonding information includes a Bluetooth Device Address and a Personal Identification Number (PIN)( ) Code.

5. The Bluetooth system according to claim 4, wherein said control unit informs the user when the RFID reader is activated.

6. The Bluetooth system according to claim 5, wherein the control unit informs the user when pairing and connection between the first Bluetooth device and the second Bluetooth device are successfully established.

7. A method for performing a pairing procedure for a Bluetooth connection, comprising the steps of:

activating an RFID reader of a Bluetooth device when a request for Bluetooth connection using a Radio Frequency Identification (RFID) is input by a user in a Bluetooth communication mode;

reading RFID information from an RFID Tag within an effective transmission and receiving range by the RFID reader; and

extracting bonding information of a counterpart Bluetooth device detected in the range from the RFID information to pair the counterpart Bluetooth device; and

pairing the first Bluetooth device using the bonding information perform Bluetooth communication.

8. The method according to claim 7, further comprising storing bonding information of the Bluetooth device in an RFID Tag of the device.

9. The method according to claim 8, wherein said bonding information includes a Bluetooth Device Address and a Personal Identification Number (PIN) Code.

10. The method according to claim 7, further comprising informing the user when the RFID reader is activated.

11. The method according to claim 7, further comprising informing the user when pairing and connection between the first Bluetooth device and the second Bluetooth device are successfully established.
