1 illustrates a system configuration for authenticating a Bluetooth device in a portable terminal according to the present invention. In the following description, it is assumed that the mobile terminal A 100 is a real user of the Bluetooth device 104.

Referring to FIG. 1, the portable terminal A 100, which is an actual user of a specific Bluetooth device, may use a pin to authenticate the specific Bluetooth device 104 to the communication server 102 in order to use the specific Bluetooth device 104. The code is requested using the additional service string (step 110). Here, the supplementary service string requesting the pin code of the Bluetooth device 104 may include address information or a manufacturing number of the Bluetooth device 104.

The communication server 102 that receives the supplementary service string requesting the pin code of the specific Bluetooth device 104 stores information on the Bluetooth devices by using the address information or the manufacturing number included in the supplementary service string. The PIN device and the actual user information of the specific Bluetooth device 104 are requested to the Bluetooth device management database 106 (step 112). As shown in FIG. 5, the Bluetooth device management database 106 includes a manufacturing number of a Bluetooth device, a Bluetooth device address, a pin code, and actual user information. The serial number, address, and pin code of the Bluetooth devices are registered when the Bluetooth devices are manufactured, and the real user information is registered when the user purchases the Bluetooth device, and the user is a real user.

The Bluetooth device management database 106 retrieves the pin code and the real user information of the Bluetooth device 104 requested from the communication server 102 and transmits it to the communication server 102 (step 114).

The communication server 102 compares the real user information provided from the database 106 with the user information of the portable terminal A 100 included in the pin code request supplementary service string.

If the two user information match, the communication server 102 transmits the pin code obtained from the Bluetooth device management database 106 to the portable terminal A 100 using an additional service string (step 116).

Thereafter, the portable terminal A 100 performs pairing with the specific Bluetooth device 104 using the pin code obtained from the communication server 102.

If the mobile terminal B 108 requests the communication server 102 to use a specific service string to request a pin code for authenticating with the specific Bluetooth device 104 (step 118). The communication server 102 having received the supplementary service string requesting the pin code from the portable terminal B 108, pins of the specific Bluetooth device to the management database 106, as in steps 112 and 114 described above. The code and the real user information are requested (step 112) to obtain the pin code and the real user information (step 114).

Thereafter, the communication server 102 compares the obtained real user information with user information of the portable terminal B 108 included in the pin code request additional service string.

If the two user information does not match, the communication server 102 checks the additional service setting state of the specific Bluetooth device. Here, the additional service setting state, when a user other than the actual user of the Bluetooth device requests a pin code of the Bluetooth device, the activation of the setting so that the Bluetooth device can be used after receiving the permission from the actual user (Activation ) And a deactivation state in which the Bluetooth device can be used without permission of the real user.

If the additional service setting state is the activation state that requires permission from the real user, the communication server 100 transmits the mobile terminal B 108 to the mobile terminal A 100 which is the real user. In step 120, a message asking whether to allow the use of the Bluetooth device 104 is transmitted.

Receiving the permission message, the mobile terminal A 100 determines whether to allow the mobile terminal B 108 to use the specific Bluetooth device 104 to provide a message containing the permission or not as an additional service. The string is transmitted to the communication server 102 (step 122).

The communication server 102 that receives the supplementary service string containing permission from the portable terminal A 100 checks whether the Bluetooth device 104 is used or not. If the portable terminal A 100 permits the use of the specific Bluetooth device 104 of the portable terminal B 108, the communication server 102 uses the retrieved pin code as a supplementary service string. It transmits to the terminal B 108 (step 124).

If the portable terminal A 100 does not allow the portable terminal B 108 to use the specific Bluetooth device 104, the communication server 102 tells the portable terminal B 108 the specific Bluetooth device. Notify that there is no right to use 104 (step 124).

On the other hand, if the additional service setting state is the deactivated state that does not require permission from the real user, the communication server 100, the communication server 102 uses the retrieved pin code using the additional service string in the portable terminal And transmits to B 108 (step 124).

Thereafter, the mobile terminal B 108 displays the message when the permission message of the specific Bluetooth device 104 is received from the communication server 102, and uses the pin code when the pin code is received. In step 126, the device performs pairing with the specific Bluetooth device 104.

For example, the digital data provided from the controller 200 is converted into an analog voice signal and output to the outside through the speaker, and the voice signal applied from the microphone is converted into digital data and provided to the controller 200. do.

3 illustrates a procedure for authenticating a Bluetooth device in a portable terminal according to an embodiment of the present invention.

Referring to FIG. 3, in step 301, if the controller 200 is in a Bluetooth device use mode for using a Bluetooth device in the vicinity, the controller 200 proceeds to step 303 to obtain a service discovery profile (SDP). Check whether a specific Bluetooth device is selected among the found peripheral Bluetooth devices.

When the specific Bluetooth device is selected, the controller 200 proceeds to step 305 and transmits an additional service string requesting a pin code for the selected specific Bluetooth device to the communication server.

For example, when requesting a pin code for a specific Bluetooth device from the server, the pin code is transmitted by sending an additional service string in a format of * # SI * [A] * [B] * [C] #SEND to the communication server. You can request Here, the SI represents a service identifier, and A represents a factor for distinguishing whether B represents address information or a manufacturing number of a Bluetooth device. In addition, B represents address information or a manufacturing number of the Bluetooth device according to the A value, and C represents whether the information to be requested is a pin code or user information.

In operation 307, the controller 200 determines whether a message is received from the communication server. When the message is received from the communication server, the controller 200 proceeds to step 309 and checks whether the received message is a pin code message of the specific Bluetooth device.

4 is a flowchart illustrating an operation procedure of a server for authenticating a Bluetooth device in a portable terminal according to an embodiment of the present invention.

Referring to FIG. 4, first, when the controller of the communication server receives the supplementary service string requesting the pin code of the Bluetooth device from the terminal in step 401, the controller of the server proceeds to step 403 to correspond to the received supplementary service string. Check the Bluetooth device information (e.g. pin code storage address, serial number, etc.) of the Bluetooth device and the requester's information (e.g. UID (Unique Identification), name, phone number, etc.).

After checking the information of the corresponding Bluetooth device and the requester information in the received additional service string, the controller of the server proceeds to step 405 by using the identified information of the Bluetooth device in the database for managing the information of the Bluetooth devices. Check the pin code of the Bluetooth device and the user's information (e.g. UID, name, phone number, etc.).

For example, when the communication server receives the PIN code request additional service string of which the manufacture number of the Bluetooth device is 'ADE05313' and the requester information is 'name: Hong Gil-dong and phone number: 010-000-0000', The Bluetooth device with the serial number 'ADE05313' is searched for in the Bluetooth device management database having the data as follows. The communication server finds that the pin code of the Bluetooth device to be used by the requester is '1947218' and the actual user information is 'UID: A32CC, name: Hong Gil-dong, and telephone number: 010-000-0000'. Can be.

After confirming the pin code of the identified Bluetooth device and the information of the real user, the controller of the server proceeds to step 407 to check whether the information of the real user and the pin code requester information match.

If the information of the real user and the pin code requester information match, the controller of the server proceeds to step 419 and transmits the identified pin code of the Bluetooth device to the requester. Terminate the algorithm.

On the other hand, if the information of the real user and the information of the pin code requester does not match, the controller of the server proceeds to step 409 and checks the additional service setting state so that the requester of the actual user to use the Bluetooth device Check whether permission is required or not.

If the permission of the actual user is not necessary, the controller of the server transmits the PIN code of the Bluetooth device to the requester by transmitting to step 419.

On the other hand, if the permission of the real user is required, the control unit of the server proceeds to step 411 and transmits an additional service string to the real user asking whether the requestor allows the use of the Bluetooth device.

In step 413, the control unit of the server checks whether an additional service string including permission from the real user is received. When the additional service string containing the usage permission is received from the real user, the control unit of the server proceeds to step 415 and checks whether the real user permits the requester to use the Bluetooth device.

If the real user does not allow the requester to use the Bluetooth device, the controller of the server proceeds to step 421 and transmits a message indicating that the requester is not authorized to use the Bluetooth device. Terminate this algorithm.

On the other hand, if the requester permits the use of the Bluetooth device, the controller of the server proceeds to step 417 and transmits the pin code of the Bluetooth device to the requester.

After that, the control unit of the server ends the present algorithm.

In the above description, the value-added service string may set whether to use the value-added service for managing the pin code of the Bluetooth device, in addition to setting whether the permission of the actual user of the Bluetooth device is required, and setting the value-added service. The status may be checked and the setting status of the additional service may be cancelled.
