Connecting system of Bluetooth device and connecting method of Bluetooth device {CONNECTING SYSTEM FOR BLUETOOTH APPARATUS AND CONNECTING METHOD FOR BLUETOOTH APPARATUS}

The present invention relates to a connection system of a Bluetooth device, and more particularly, to a connection system of a Bluetooth device capable of effectively connecting between Bluetooth devices by improving a connection authentication procedure for a Bluetooth device, a method of connecting a Bluetooth device, and an authentication server and a Bluetooth device. It is about.

Recently, the use of Bluetooth communication technology for the transmission and reception of information through wireless communication in the mobile environment has been increasing. The Bluetooth communication is a communication standard that enables real-time communication in both directions by connecting wirelessly between Bluetooth devices located in a short distance.

Bluetooth devices employing such Bluetooth communication require an authentication procedure for connection between devices in order to wirelessly connect and exchange information therebetween. This authentication process is performed in the process of performing a Bluetooth connection between the Bluetooth devices, briefly described as follows.

First of all, the Bluetooth devices (eg, primary Bluetooth device and secondary Bluetooth device) that the user wants to interconnect with each other are located. Accordingly, the primary Bluetooth device requests a connection to the secondary Bluetooth device. Accordingly, the secondary Bluetooth device requests the PIN code, and as the user inputs the PIN code of the secondary Bluetooth device through the input unit of the primary Bluetooth device, the primary Bluetooth device provides the PIN code requested by the secondary Bluetooth device to the secondary Bluetooth device. . Therefore, if the provided PIN code is justified, the authentication procedure is completed, and the secondary Bluetooth device and the primary Bluetooth device are connected through mutual Bluetooth communication.

As such, a PIN code is uniquely used for authentication between Bluetooth devices, and in general, a Bluetooth device that does not have an interface for inputting a PIN code, such as a hands-free printer or a printer, has a simple fixed PIN code (eg, 0000, 1111, 1234, etc.), and a Bluetooth device having an interface for inputting a PIN code, such as a mobile phone, can arbitrarily set / change a PIN code.

In the conventional authentication procedure as described above, the user must know and input a valid PIN code for the PIN code request of the secondary Bluetooth device through the primary Bluetooth device. Therefore, if a user purchases a Bluetooth device (eg, a headset) legitimately for use, the PIN code described in the manual of the purchased Bluetooth device can be entered during the authentication process, but the PIN code is lost due to the loss of the manual. If the user does not know the difficulty of completing the authentication process of the Bluetooth device. In addition, when a user wants to borrow a Bluetooth device not purchased by the user, there is a hassle of asking and finding the PIN code of the Bluetooth device borrowed from the user who borrowed the Bluetooth device. In addition, when the secondary Bluetooth device has an interface for inputting a PIN code, such as a mobile phone, and any user has changed the PIN code, the user who does not know the changed PIN code at the time of authentication has difficulty in completing the authentication procedure. Will suffer.

Based on the authentication information (for example, authentication information of the first part Bluetooth device 20), it is determined whether to allow connection establishment between the second Bluetooth device (eg, the first part Bluetooth device 20) and the main Bluetooth device 10. It is desirable to. In particular, the server control module 82, the device type information and sharing information and Bluetooth group information of the Bluetooth device that can be connected among the corresponding authentication information retrieved corresponding to the secondary Bluetooth device (for example, the first secondary Bluetooth device 20), On the basis of the device type information and the Bluetooth group information of the primary Bluetooth device 10, it is determined whether to allow the connection setting between the secondary Bluetooth device (for example, the first secondary Bluetooth device 20) and the primary Bluetooth device 10. desirable.

If it is determined that the connection setting is allowed, the server control module 82 returns the authentication information of the secondary Bluetooth device (for example, the first secondary Bluetooth device 20) to the primary Bluetooth device 10. In this case, the server control module 82 preferably returns an authentication response including PIN code information among the authentication information of the secondary Bluetooth device (eg, the first secondary Bluetooth device 20) to the primary Bluetooth device 10. .

For example, when the Bluetooth group A (A) and the Bluetooth group C (C) are stored in the shared information of the first part Bluetooth device 20, the server control module 82 may include the first part Bluetooth device 20. And the connection establishment between the main Bluetooth device 10 in the Bluetooth group A (A) is allowed. In addition, even when the first part Bluetooth device 20 is connected to the main Bluetooth device 40 of the Bluetooth group C (C), the server control module 82 is configured to perform the first part Bluetooth device 20 and the Bluetooth group C ( It will be determined that connection establishment between the main Bluetooth devices 40 in C) is allowed. When the first part Bluetooth device 20 is connected to the main Bluetooth device 60 of the Bluetooth group B (B), the server control module 82 is based on the shared information of the first part Bluetooth device 20. It is determined that the connection setting between the main Bluetooth device 60 in the Bluetooth group B (B) is not allowed, and will return a response indicating that the authentication response is not returned or not allowed to the main Bluetooth device 60.

In addition, if the device type of the main Bluetooth device 10 does not correspond to the connectable Bluetooth device based on the device type information of the connectable Bluetooth device of the first part Bluetooth device 20, the server control module 82 is connected. It will determine that the setting is not allowed and will reply back to the primary Bluetooth device 10 not replying or notifying it is not allowed.

Here, there is a secondary Bluetooth device that can change the PIN code of the third secondary Bluetooth device 40 through the key input unit 45 like the third secondary Bluetooth device 40. Accordingly, the main Bluetooth module 11 is the authentication information of the secondary Bluetooth device (eg, the third Bluetooth device 40) in a state connected to the secondary Bluetooth device (eg, the third Bluetooth device 40) via Bluetooth. If there is changed information (eg, PIN code information or shared information), it is preferable to provide the changed information to the authentication server 100. This changed information will be provided to the main Bluetooth module 11 from the Bluetooth module (eg, the third part Bluetooth module 41) of the secondary Bluetooth device (eg, the third part Bluetooth device 40).

Accordingly, the server control module 82 of the authentication server 100, if the changed information is provided among the authentication information of the secondary Bluetooth device (for example, the third secondary Bluetooth device 40) from the primary Bluetooth device 10, the memory module The authentication information corresponding to the secondary Bluetooth device (for example, the third secondary Bluetooth device 40) may be updated with the changed information.

Alternatively, if there are secondary Bluetooth devices 20, 30, and 40 that are released while the primary Bluetooth module 11 is connected, the primary Bluetooth module 11 of the secondary Bluetooth device (eg, the third secondary Bluetooth device 40) that is disconnected at the time of disconnection is present. It is preferable to provide the authentication information to the authentication server (100).

If it recognizes it requires a connection to the third part Bluetooth device 40 (S30).

Thus, when the main Bluetooth device 10 is connected to the third Bluetooth device 40, the authentication server 100 requests the authentication of the third Bluetooth device 40 (S40). The authentication server 100 that has been requested for authentication retrieves authentication information of the third part Bluetooth device 40 from the authentication related information 82 and provides it to the main Bluetooth device 20 (S50).

Accordingly, the main Bluetooth device 10 that has received the authentication information corresponding to the third part Bluetooth device 40 performs the authentication procedure of the third part Bluetooth device 40 based on the provided authentication information, and performs the third part Bluetooth. Bluetooth connection with the device 40 may be performed (S60).
