Abstract

A Bluetooth device and its pairing method capable of performing an accurate pairing with a user-desired Bluetooth device provide e transmitting an inquiry message for searching for at least one peripheral Bluetooth device, and in response the peripheral Bluetooth device transmits an inquiry response message including predefined pairing acceptance mark data, then upon receiving the inquiry response message including the pairing acceptance mark data, the Bluetooth device transmits a pairing request message for pairing to the peripheral Bluetooth device that forwarded the inquiry response message.

First claim

What is claimed is:

1. A Bluetooth pairing method comprising:
transmitting an inquiry message for searching at least one peripheral Bluetooth device;
receiving an inquiry response message from the at least one peripheral Bluetooth device in response to the inquiry message;
determining whether the receivd inquiry response message includes predefined pairing acceptance mark data;
determining whether the pairing acceptance mark data is set to an ON state, when the received inquiry response message includes the pairing acceptance mark data;
ignoring the received inquiry response message, when the received inquiry response message does not include the pairing acceptance mark data or the pairing acceptance mark data is set to an OFF state; and
transmitting a pairing request message to the at least one peripheral Bluetooth device for pairing, when the received inquiry response message includes the pairing acceptance mark data and the pairing acceptance mark data is set to the ON state.

2. The Bluetooth pairing method of claim 1 , wherein the pairing acceptance mark data is included as Extended Inquiry Response (EIR) data in an EIR of the inquiry response message.

3. A Bluetooth pairing method comprising:
transmitting an inquiry message for searching at least one peripheral Bluetooth device during a preset search time period;
receiving an inquiry response message from the at least one peripheral Bluetooth device in response to the inquiry message;
determining whether the received inquiry response message includes predefined pairing acceptance mark data;
determining whether the pairing acceptance mark data is set to an ON state, when the received inquiry response message includes the pairing acceptance mark data;
ignoring the received inquiry response message, when the received inquiry response message does not include the pairing acceptance mark data or the pairing acceptance mark data is set to an OFF state;
determining the at least one peripheral Bluetooth device that forwarded the inquiry response message as a pairing acceptance mark device, when the received inquiry response message includes the pairing acceptance mark data and the pairing acceptance mark data is set to the ON state;
checking a number of pairing acceptance mark devices which are found during the preset search time period;
transmitting a pairing request message to the pairing acceptance mark device for pairing when only one pairing acceptance mark device found; and
displaying a Bluetooth device list including the found pairing acceptance mark devices marked according to a predetermined format to distinguish the found pairing acceptance mark devices from other Bluetooth devices when more than one pairing acceptance mark device are found.

4. The Bluetooth pairing method of claim 3 , wherein the pairing acceptance mark data is included as Extended Inquiry Response (EIR) data in an EIR of the inquiry response message.

5. A Bluetooth pairing method comprising:
receiving an inquiry message from a Bluetooth device;
checking a pairing acceptance setting;
transmitting an inquiry response message including predefined pairing acceptance mark data which is set to an OFF state to the Bluetooth device, when the pairing acceptance setting is set to an OFF state;
transmitting an inquiry response message including the pairing acceptance mark data which is set to an ON state to the Bluetooth device, when the pairing acceptance setting is set to an ON state;
receiving a pairing request message from the Bluetooth device; and
performing a pairing with the Bluetooth device.

6. The Bluetooth pairing method of claim 5 , wherein the transmitting comprises including a pairing acceptance mark data as Extended Inquiry Response (EIR) data in an EIR of the inquiry response message.

7. The Bluetooth pairing method of claim 6 , further comprising setting the pairing acceptance setting to the ON state when a predetermined motion of a Bluetooth device which checks the pairing acceptance setting is sensed.

8. The Bluetooth pairing method of claim 6 , further comprising setting the pairing acceptance setting to the ON state when a predetermined user input is detected.

9. A Bluetooth apparatus comprising:
a Bluetooth unit for performing Bluetooth communication; and
a controller, coupled to the Bluetooth unit, configured to:
transmit an inquiry message for searching at least one peripheral Bluetooth device,
receive an inquiry response message from the at least one peripheral Bluetooth device in response to the inquiry message;
determine whether the received inquiry response message includes predefined pairing acceptance mark data;
determine whether the pairing acceptance mark data is set to an ON state, when the received inquiry response message includes the pairing acceptance mark data;
ignore the received inquiry response message, when the received inquiry response message does not include the pairing acceptance mark data or the pairing acceptance mark data is set to an OFF state; and
transmit a pairing request message to the at least one Bluetooth device for pairing, when the received inquiry response message includes the pairing acceptance mark data and the pairing acceptance mark data is set to the ON state.

10. The Bluetooth apparatus of claim 9 , wherein the pairing acceptance mark data is included as Extended Inquiry Response (EIR) data in an EIR of the inquiry response message.

11. A Bluetooth apparatus comprising:
a Bluetooth unit for performing Bluetooth communication;
a display for displaying a Bluetooth device list; and
a controller, coupled to the Bluetooth unit and the display, configured to:
transmit an inquiry message for searching at least one peripheral Bluetooth device during a preset search time period;
receive an inquiry response message from the at least one peripheral Bluetooth device in response to the inquiry message;
determine whether the received inquiry response message includes predefined pairing acceptance mark data;
determine whether the pairing acceptance mark data is set to an ON state, when the received inquiry response message includes the pairing acceptance mark data;
ignore the received inquiry response message, when the received inquiry response message does not include the pairing acceptance mark data or the pairing acceptance mark data is set to an OFF state;
determine the at least one peripheral Bluetooth device that forwarded the inquiry response message as a pairing acceptance mark device, when the received inquiry response message includes the pairing acceptance mark data and the pairing acceptance mark data is set to the ON state;
check a number of pairing acceptance mark devices which are found during the preset search time period;
transmit a pairing request message to the pairing acceptance mark device for pairing when only one pairing acceptance mark device is found; and
display a Bluetooth device list including the found pairing acceptance mark devices marked according to a predetermined format to distinguish the found pairing acceptance mark devices from other Bluetooth devices when more than one pairing acceptance mark devices are found.

12. The Bluetooth apparatus of claim 11 , wherein the pairing acceptance mark data is included as Extended Inquiry Response (EIR) data in an EIR of the inquiry response message.

13. A Bluetooth apparatus comprising:
a Bluetooth unit for performing Bluetooth communication; and
a controller, coupled to the Bluetooth unit, configured to:
receive an inquiry message from a Bluetooth device;
check a pairing acceptance setting;
transmit an inquiry response message including predefined pairing acc
