Abstract

A method and apparatus for a bonding process in a user terminal having a Bluetooth module. The method includes recognizing a barcode of a Bluetooth device to be connected using a camera module, acquiring bonding information of the Bluetooth device from the barcode, performing pairing with the Bluetooth device using the acquired bonding information, and establishing a connection between the user terminal and the Bluetooth device after performing pairing. The bonding information may also be acquired using a secure cable in another embodiment.

Claims

1. A method for a bonding process in a user terminal having a Bluetooth module, the method comprising the steps of:

recognizing a barcode of a Bluetooth device to be connected using a camera module;

acquiring bonding information of the Bluetooth device from the barcode;

performing pairing with the Bluetooth device using the acquired bonding information; and

establishing a connection between the user terminal and the Bluetooth device after performing pairing.

2. The method of claim 1, wherein the bonding information includes an address of the Bluetooth device.

3. The method of claim 1, wherein the step of performing pairing comprises the steps of:

requesting a Personal Identification Number (PIN) code from the Bluetooth device and receiving a user-input PIN code from the Bluetooth device, if the user terminal is in a security mode; and

determining that authentication is successful if the received PIN code is correct if the user terminal is in the security mode, and link keys are exchanged with the Bluetooth device.

4. The method of claim 3, wherein the link keys are a common link key assigned according to the PIN code.

5. A method for a bonding process in a user terminal having a Bluetooth module, the method comprising the steps of:

connecting to a Bluetooth device using a secure cable;

acquiring Bluetooth information of the Bluetooth device and providing bonding information of the user terminal through the secure cable;

performing pairing with the Bluetooth device using the acquired bonding information; and

establishing a connection between the user terminal and the Bluetooth device after performing pairing.

6. The method of claim 5, wherein the bonding information includes an address of the Bluetooth device.

7. The method of claim 5, wherein the step of performing pairing comprises the steps of:

requesting a Personal Identification Number (PIN) code from the Bluetooth device and receiving a user-input PIN code from the Bluetooth device, if the user terminal is in a security mode;

determining that authentication is successful if the received PIN code is correct if the user terminal is in the security mode, and link keys are exchanged with the Bluetooth device.

8. The method of claim 7, wherein the link keys are a common link key assigned according to the PIN code and are exchanged through the secure cable.

9. An apparatus for a bonding process in a user terminal having a Bluetooth module, the apparatus comprising:

a controller for recognizing a request from a user for a connection to a Bluetooth device using a barcode system;

a camera module for sensing a barcode of the Bluetooth device under the control of the controller;

a barcode recognizing unit for analyzing the barcode sensed by the camera module and acquiring bonding information of the Bluetooth device; and

the Bluetooth module for performing pairing with the Bluetooth device using the acquired bonding information of the Bluetooth device.

10. An apparatus for a bonding process in a user terminal having a Bluetooth module, the apparatus comprising:

a controller for recognizing a request from a user for a connection to a Bluetooth device using a secure cable;

a cable connection unit for recognizing the secure cable connected to the Bluetooth device under the control of the controller, acquiring bonding information of the Bluetooth device through the secure cable, and providing bonding information of the user terminal; and

the Bluetooth module for performing pairing with the Bluetooth device using the acquired bonding information.

11. The apparatus of claim 10, wherein the secure cable includes a Universal Asynchronous Receiver/Transmitter (UART) receiver, a UART transmitter, and a ground line.
