Description

TECHNICAL FIELD [0001] The present invention relates to a Bluetooth communication method and a Bluetooth device and system supporting the Bluetooth communication method.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a Bluetooth communication method using a Bluetooth device, a Bluetooth device and a system supporting the Bluetooth communication method, and more particularly to a Bluetooth communication method capable of quickly connecting a Bluetooth communication device with a target Bluetooth device using information transmitted / And a Bluetooth device and system supporting the same.

Generally, Bluetooth refers to a standard that enables real-time communication in a bidirectional manner by wirelessly connecting computers, mobile terminals, household appliances, etc. located in a short distance. Bluetooth uses a 2.45-MHz ISM (Industrial Scientific Medical) band radio frequency (RF), which does not require a wireless license, to send and receive voice and data without physical cables to various digital devices. Support.

On the other hand, a device equipped with a Bluetooth module supporting Bluetooth communication (hereinafter referred to as a 'Bluetooth device') searches neighboring Bluetooth devices located within a transmission distance to connect with another Bluetooth device. At this time, the procedure of searching for another Bluetooth device is performed by an inquiry process and a name discovery process.

First, the Bluetooth device switches the mode of the Bluetooth module to 'Inquiry Mode' according to 'Inquiry Command' and then transmits an inquiry message through the Bluetooth module And broadcasts them so that nearby Bluetooth devices can receive them.

Then, the neighboring bluetooth devices receiving the inquiry message broadcasted by the Bluetooth device transmit an inquiry result message to the Bluetooth device in response to the inquiry message. The Bluetooth device having received at least one inquiry result message in response to the inquiry message from the peripheral Bluetooth terminals collects and interprets at least one inquiry result message transmitted from at least one peripheral Bluetooth device, To the Bluetooth device user through the display unit.

Next, the discovery process will be described. After performing the above-described inquiry process, a name discovery process for searching for the names of the neighboring bluetooth devices searched through the inquiry process is performed. In this case, the name discovery process transmits a 'Name Request' message to the neighboring Bluetooth devices searched through the inquiry process, receives the device name from the neighboring bluetooth device in response to the 'Name Request message' And provides it to a Bluetooth device user.

In general, the device name of a Bluetooth module mounted on a Bluetooth device is set to an arbitrary value (for example, Anycall, CYON, SKY, Curitel, etc.) for each manufacturer.

Accordingly, when a plurality of Bluetooth devices of the same type or the same manufacturer exist in the periphery, the device name searched by the Bluetooth device search procedure frequently occurs in the same device name.

Therefore, the Bluetooth device displays the device name of the searched Bluetooth device together with the address of the Bluetooth device (in particular, the BD_ADDR of the Bluetooth module) obtained through the inquiry process, considering the case where the searched device name is the same. However, the user of the Bluetooth device has a problem that it is difficult to know exactly which device is the target Bluetooth device to which the Bluetooth communication is to be connected with only the device name and the BD_ADDR. In order to solve such a problem, the Bluetooth terminal user has the same trouble to directly inquire the BD_ADDR of the Bluetooth device to the user of the Bluetooth device to connect.

In addition, the Bluetooth device user has the inconvenience of memorizing the 48-bit BD_ADDR, which is the unique address of the Bluetooth module mounted on the own device, or recording the BD_ADDR in the separate recording means.

Accordingly, the Bluetooth device may provide a menu that can determine a Bluetooth mode of operation in response to a user request, as shown at reference numeral 110. Then, the user can set the Bluetooth execution mode to either the calling mode 120 or the receiving mode 160 through the menu.

The calling mode 120 indicates a mode in which the Bluetooth device selects a target Bluetooth device that is a subject of Bluetooth communication and requests a Bluetooth connection directly. That is, the calling mode 120 indicates an active mode in which the Bluetooth device requests a Bluetooth communication connection to a target Bluetooth device. The receiving mode 160 is a mode in which the Bluetooth device transmits its identification information to a target Bluetooth device that desires to communicate with Bluetooth and the target Bluetooth device requests a Bluetooth communication connection to the Bluetooth device based on the identification information . That is, the receiving mode 160 may be a passive mode in which the Bluetooth device receives a Bluetooth communication connection from a destination Bluetooth device. Therefore, the Bluetooth device can perform the Bluetooth communication connection operation corresponding to the Bluetooth execution mode set as described above.

When the Bluetooth mode 110 is set to the calling mode 120, the Bluetooth device is connected to a coverage area (e.g., a piconet area) of the Bluetooth communication through an inquiry process and a discovery process, And collects information from at least one nearby peripheral Bluetooth device. The information includes identification information to be described later, and the identification information includes a telephone number of the Bluetooth device, a user name of the Bluetooth device, a device name of the Bluetooth module, and a unique address (BD_ADDR) of the Bluetooth module. Particularly, in the present invention, the identification information is at least one of a telephone number and a user name of each Bluetooth device. The user name may be a user name, an alias, or the like as a name given to the device by the corresponding device user. And the identification information may be obtained using a message service. Next, the Bluetooth device requests a Bluetooth communication connection to the target Bluetooth device using the collected information as indicated by reference numeral 140. When the Bluetooth device receives a response corresponding to the Bluetooth connection request from the target Bluetooth device, the Bluetooth device connects the communication with the target Bluetooth device as indicated by reference numeral 150. [ The detailed operation in the calling mode 120 will be described in detail with reference to the following drawings.

In contrast, when the Bluetooth mode 110 is set to the reception mode 160, the Bluetooth device generates a Bluetooth message as indicated by reference numeral 170 in response to a Bluetooth connection request by the user's reception mode, And transmits the message to the destination Bluetooth device by the telephone number obtained from the user. Here, the Bluetooth message includes identification information of the Bluetooth device. The identification information may further include at least one of a user name and a telephone number of the Bluetooth device, a unique address (BD_ADDR) of the Bluetooth module mounted on the Bluetooth device, and the like. Next, the Bluetooth device can receive a Bluetooth communication connection request from the target Bluetooth device, as shown at reference numeral 180. Then, the Bluetooth device transmits a response corresponding to the Bluetooth communication connection request and connects a communication with the target Bluetooth device as indicated by reference numeral 190. The detailed operation in the reception mode 160 will be described in detail with reference to the following drawings.

Hereinafter, the Bluetooth communication method proposed by the present invention and the devices and systems supporting the Bluetooth communication method will be described in detail according to the Bluetooth mode of operation. That is, in the following, a Bluetooth communication method according to the calling mode, a Bluetooth communication method according to the receiving mode, and a device and a system supporting the Bluetooth communication method will be described in detail.

2 is a diagram illustrating a Bluetooth communication connection process between Bluetooth devices according to an embodiment of the present invention. In particular, FIG. 2 is a view for explaining an operation in which the Bluetooth mode of the present invention performs a Bluetooth communication connection based on a reception mode.

2, the first device 100 represents a Bluetooth device that wants to communicate with the second device 200 in response to a user request, and the second device 200 includes a first device 100 The first device 100 transmits a Bluetooth communication request to the first device 100 based on information transmitted from the first device 100.

First, when the first device 100 requests the user to execute the Bluetooth function, the first device 100 may provide a menu related to the Bluetooth function through the display unit. Then, the user of the first device 100 can determine the Bluetooth mode for Bluetooth communication in the related menu. FIG. 2 shows an example of a case where the Bluetooth mode is operated in a reception mode. Accordingly, the user can select, for example, a < BT message generation > menu for generating a Bluetooth message on the basis of the reception information (telephone number, user name, alias, etc.) in the related menu.

Then, the first device 100 may provide an input screen for inputting the reception information in response to the <BT message generation> menu selection. The user can input the reception information of a specific Bluetooth device (for example, the second device 200) that wants to communicate with the Bluetooth on the input screen and generate an input signal for requesting transmission. The reception information may be input in the form of a phone number of the second device 200 or a user name or an alias set in the phone book by the user of the first device 100 as the user information of the second device 200 have. The reception information may include a plurality of pieces of reception information for a plurality of devices.

Next, when the generated input signal is transmitted, the first device 100 generates a Bluetooth message (step 201), and transmits the generated Bluetooth message to the second device 200 based on the received information (Step 203). Here, the received information is transmitted based on a data communication channel by a message service. If the received information is a user name or an alias, the first device 100 may extract the telephone number corresponding to the user name or alias and transmit the extracted telephone number to the second device 200 based on the telephone number. At this time, the first device 100 may generate identification information of the first device 100 when generating the Bluetooth message. The identification information may additionally include a phone number of the first device 100 as well as a unique address of a Bluetooth module of the first device 100 (hereinafter referred to as BD_ADDR). In addition, the first device 100 may include an identifier for indicating that the Bluetooth message is a message including the BD_ADDR of the first device for Bluetooth communication in a header of the message.

Next, the second device 200 parses the Bluetooth message when receiving the Bluetooth message from the first device 100 (step 205). Thus, the second device 200 can acquire the BD_ADDR of the first device 100. At this time, when the second device 200 receives the specific message from the first device 100, the second device 200 may analyze the message and perform step 205 corresponding to the type of the message. For example, the second device 200 may check the header of the message and if the identifier exists, recognize that the message is the Bluetooth message, the second device 200 may perform the above-described parsing operation.

Next, when the second device 200 acquires the BD_ADDR of the first device 100 from the Bluetooth message, the second device 200 transmits a Bluetooth connection request signal to the first device 100 based on the BD_ADDR (step 207 step). At this time, the Bluetooth connection request signal is transmitted based on the Bluetooth communication channel.

Next, when the first device 100 receives the Bluetooth connection request signal from the second device 200, the first device 100 transmits a Bluetooth connection response signal corresponding to the Bluetooth connection request signal to the second device 200 (Step 209). At this time, the Bluetooth connection response signal is transmitted based on the Bluetooth communication channel. The first device 100 and the second device 200 form a Bluetooth communication channel to perform Bluetooth communication according to a user's request (step 211).

3 is a diagram illustrating a Bluetooth communication method performed in a device according to an embodiment of the present invention based on a receiving mode.

Referring to FIG. 3, FIG. 3 illustrates a Bluetooth communication method of a device that receives a Bluetooth connection request signal when the Bluetooth mode of the present invention is Bluetooth communication based on a reception mode. For example, FIG. 3 may be a Bluetooth communication method corresponding to the first device 100 of FIG.

First, the first device 100 activates the Bluetooth mode in a use state in response to a user request and provides a menu related to the Bluetooth function (step 301). At this time, if the first device 100 is already in the Bluetooth mode activation state, the activation process may be omitted.

Next, the first device 100 may determine whether a <BT message generation> menu is selected in the related menu (step 303). If the < Create BT message > menu is not selected (No in step 303), the first device 100 can perform a corresponding operation according to a user request (step 305). For example, the first device may perform an operation for Bluetooth communication, disable the Bluetooth mode, or perform an operation corresponding to a general Bluetooth communication procedure in a calling mode as described later.

On the other hand, if the < Create BT message > menu is selected (Yes in step 303), the first device 100 executes the Bluetooth message generation mode (step 307). For example, the first device 100 may provide an input screen for inputting reception information. The input screen may be provided in a form similar to a general message creation screen, but only a field for inputting the contents of a message body may be omitted. That is, in the case of the Bluetooth message, the first device 100 transmits the BD_ADDR of the first device 100, and the first device 100 automatically configures the BD_ADDR as the contents of the body in the Bluetooth message configuration The field for inputting the content of the main text can be omitted.

Next, the first device 100 may input at least one reception information corresponding to an input signal generated by the user (step 309). Herein, the reception information may be input in the form of a phone number of the target Bluetooth device to which the Bluetooth communication connection is desired, a user name or a nickname registered in the phone book as the target Bluetooth device user information by the user of the first device 100 . The reception information may include a plurality of pieces of reception information for a plurality of different devices.

Next, the first device 100 extracts a BD_ADDR of the first device 100 when an input signal for requesting Bluetooth message transmission is generated after the reception information is input (step 313). Specifically, the first device 100 can extract the BD_ADDR, which is a unique address of the Bluetooth module, from the storage unit of the first device 100 or the storage unit of the Bluetooth module. That is, the BD_ADDR of the Bluetooth module may be stored in at least one of the storage unit of the first device 100 and the storage unit of the Bluetooth module.

Next, the first device 100 generates a blue pitcher message having the BD_ADDR as the main content of the message (step 315). At this time, the first device 100 may configure the BD_ADDR of the first device 100 in the payload area of the Bluetooth message when generating the Bluetooth message. The first device 100 may include an identifier indicating that the message type is a Bluetooth message in the Bluetooth message header area. Also, the first device 100 may include its own phone number in the Bluetooth message.

Next, the first device 100 transmits the Bluetooth message based on the received number (step 317). At this time, the first device 100 can transmit the Bluetooth message based on the message service. Accordingly, the first device 100 forms a data communication channel for the message service and transmits the Bluetooth message on the basis of a message service through the data communication channel.

Next, the first device 100 forms a Bluetooth communication channel with at least one specific Bluetooth device (e.g., the second device 200) corresponding to the reception number after transmitting the Bluetooth message (step 319) Bluetooth communication with a specific Bluetooth device can be performed (Step 321). That is, when the first device 100 receives a Bluetooth connection request signal from the specific Bluetooth device, it transmits a Bluetooth connection response signal corresponding to the Bluetooth connection request signal to form a Bluetooth communication channel between the first and second devices. The first device 100 may perform Bluetooth communication corresponding to a user request with the specific Bluetooth device through the Bluetooth communication channel.

4 is a diagram illustrating a Bluetooth communication method performed in a device according to an embodiment of the present invention based on a receiving mode.

Referring to FIG. 4, FIG. 4 illustrates a Bluetooth communication method of a device for transmitting a Bluetooth connection request signal when the Bluetooth mode of the present invention is Bluetooth communication based on a reception mode. For example, FIG. 4 may be a Bluetooth communication method corresponding to the second device 200 of FIG.

In operation 403, the second device 200 may analyze a type of the received specific message when receiving the specific message in operation 401 (S403). The second device 200 can analyze the type of the specific message by checking the header of the specific message when receiving the specific message. Here, the specific message is transmitted based on a data communication channel by a message service.

Next, in step 405, the second device 200 determines whether the received specific message type is a Bluetooth message for Bluetooth communication. If the type of the specific message is not the Bluetooth message (No in step 405), the second device 200 may perform a normal message processing operation according to a setting method or a user request (step 407).

On the other hand, if the type of the specific message is the Bluetooth message (Yes in step 405), the second device 200 parses the Bluetooth message (step 409), thereby extracting the BD_ADDR included in the Bluetooth message 411). Here, the BD_ADDR may be a BD_ADDR of the first device 100 that transmitted the Bluetooth message.

Next, in step 413, the second device 200 may output a pop-up window having a predetermined format when extracting the BD_ADDR. At this time, the second device 200 may provide the BD_ADDR, user information about the first device 100, Bluetooth connection guide information, and the like when the pop-up window is output. For example, the second device 200 may inform that the Bluetooth communication is desired from the first device 100 having the BD_ADDR. Accordingly, the second device 200 may provide the BD_ADDR of the first device 100, the user information of the first device 100, and the guide information in the pop-up window. Here, the user information may be a phone number of the first device 100. If the phone number of the first device 100 is a phone number registered in the phone book of the second device, the user information may be provided in the phone book as a user name or alias set corresponding to the phone number. In addition, the second device 200 may additionally generate an effect sound or vibration set at the time of outputting the pop-up window.

Next, the second device 200 checks whether there is a connection request to connect the Bluetooth communication from the user or according to the setting method (step 415). For example, when the second device 200 is set as an automatic operation upon reception of the Bluetooth message, the second device 200 can process the connection request when a predetermined time elapses after the pop-up window is output. Alternatively, in the case of the automatic method, the pop-up window output step may be omitted and the connection request may be checked immediately and the connection request may be generated when a predetermined time elapses. In addition, when the second device 200 is set as a manual operation mode upon reception of the Bluetooth message, the second device 200 can wait for the user to generate an input signal after outputting the pop-up window. When an input signal for requesting a connection request is generated from the user, the connection request can be processed as being generated.

If the connection request is not received (No in step 415), the second device 200 may perform a corresponding operation requested by the user (step 417). For example, the second device 200 may store the BD_ADDR and the telephone number of the first device 100 obtained based on the Bluetooth message. If the BD_ADDR and the telephone number of the first device 100 are not registered in the phone book of the second device 200, the storage may be stored according to the user's selection. Alternatively, the second device 200 may store the Bluetooth message in a predetermined area (e.g., a message area) in response to a user request and enter the pre-reception step.

The second device 200 forms a Bluetooth communication channel with the first device 100 based on the extracted BD_ADDR (step 415) when there is a Bluetooth communication connection request (step 415) The Bluetooth communication with the first device 100 can be performed (Step 421). That is, when the second device 200 transmits a Bluetooth connection request signal for requesting a Bluetooth communication connection to the first device 100 and receives a Bluetooth connection response signal from the first device 100 in response thereto So that a Bluetooth communication channel can be formed between both sides. Specifically, the second device 200 generates a Bluetooth connection request signal in response to the connection request of the user, and transmits the Bluetooth connection request signal to the first device 100 based on the extracted BD_ADDR. Here, the Bluetooth connection request signal is transmitted based on a Bluetooth communication channel. When the second device 200 receives the Bluetooth connection response signal corresponding to the Bluetooth connection request signal from the first device 100, the second device 200 forms a Bluetooth communication channel with the first device 100, It is possible to perform corresponding Bluetooth communication.

In the above description, the Bluetooth communication method and the devices and systems supporting the Bluetooth communication mode in the Bluetooth mode of the present invention have been described. Hereinafter, a Bluetooth communication method and a device and a system supporting the Bluetooth communication method in a Bluetooth mode of the present invention will be described.

FIG. 5 is a diagram illustrating a Bluetooth communication connection process between Bluetooth devices according to an embodiment of the present invention. Referring to FIG. In particular, FIG. 5 is a view for explaining an operation of the Bluetooth execution mode of the present invention performing a Bluetooth communication connection based on a calling mode.

5, the first device 100 responds to a user request by sending a request to a second device 200 (e.g., a second device 200 to a fourth device 400) of a plurality of peripheral Bluetooth devices The second device 200, the third device 300 and the fourth device 400 indicate peripheral Bluetooth devices existing in the vicinity of the first device 100, And the second device 200 among the peripheral Bluetooth devices represents a target Bluetooth device for which the first device 100 desires to perform Bluetooth communication.

First, when the first device 100 requests the user to execute the Bluetooth function, the first device 100 may provide a menu related to the Bluetooth function through the display unit. Then, the user of the first device 100 can determine the Bluetooth mode for Bluetooth communication in the related menu. FIG. 5 shows an example of a case where the Bluetooth mode is operated in the calling mode. Accordingly, the user can select, for example, the < peripheral device search > menu from the related menu.

In response to the < peripheral device search > menu selection, the first device 100 switches the mode of the Bluetooth module to 'Inquiry Mode' and transmits an inquiry message to the neighboring Bluetooth devices , The second device 200 to the fourth device 400) (step 501).

Next, the second device (200) to the fourth device (400) receiving the inquiry message broadcast by the first device (100) transmits an inquiry result message in response to the inquiry message, To the first device 100 (Step 503). At this time, the second device (200) to the fourth device (400) transmit their own BD_ADDR in the inquiry result message.

Next, when the first device 100 receives the inquiry result message from the second device 200 to the fourth device 400, the first device 100 receives the inquiry result message from the second device 200 to the fourth device 400, (Step 505). Here, the transmission may be a multicasting type transmission that is limited to the second device 200 to the fourth device 400 transmitting the inquiry result message. The name request message may be transmitted on the basis of a Bluetooth communication channel or on a data communication channel based on a message service corresponding to the setting method. However, it is preferable that the name request message is transmitted on the basis of the Bluetooth communication channel in connection with charging for using the message service of the first device 100.

Next, when receiving the name request message from the first device 100, the second device 200 to the fourth device 400 transmit a name response message in response to the name request message, To the first device 100 (Step 507). At this time, the second device (200) to the fourth device (400) transmit their own identification information in the name response message.

The identification information may further include a telephone number of each of the second device 200 to the fourth device 400, a user name of each device, a BD_ADDR of each device, a device name of each device, and the like. That is, the identification information included in the name response message is set to a value (e.g., a phone number) that identifies each device on which the corresponding Bluetooth module is mounted, rather than a value set by a manufacturer. Here, the name response message may be transmitted based on a Bluetooth communication channel or may be transmitted based on a data communication channel by a message service corresponding to the setting method. However, it is preferable that the first device 100 be provided with a charge generated when the second device 200 through the fourth device 400 transmit the name response message based on the message service. When the name response message is transmitted based on the message service, the second device (200) to the fourth device (400) transmit an identifier for indicating that the type of the transmitted message is a message including the identification information And can be included in the header of the message.

Next, when the first device 100 receives the name response message from the second device 200 to the fourth device 400, the first device 100 collects the respective identification information included in the name response messages, To the user. For example, the first device 100 may be a Bluetooth device having identification information selected by the user among the identification information of the second device 200 to the fourth device 300, (Step 509 and step 511) to perform Bluetooth communication (step 509).

Specifically, the first device 100 transmits a Bluetooth connection request signal to the second device 200 based on the identification information (step 509). At this time, the Bluetooth connection request signal is transmitted based on the Bluetooth communication channel. If the Bluetooth connection request signal is received, the second device 200 may transmit a Bluetooth connection response signal to the first device 100 in response to the Bluetooth connection request signal (step 511). At this time, the Bluetooth connection response signal is transmitted based on the Bluetooth communication channel. The first device 100 and the second device 200 form a Bluetooth communication channel to perform Bluetooth communication according to a user's request (step 513).
