The controller 120 receives a search keyword of content data to be searched for from a user in the content data search mode according to an exemplary embodiment of the present invention. Then, the control unit 120 generates the search information for the content data and transmits it to one or more other mobile communication terminals of the piconet through the Bluetooth module 130. Thereafter, the controller 120 determines whether there is content data corresponding to the search information transmitted through a response message received from another mobile communication terminal. Therefore, when receiving the response message, the controller 120 controls to download the searched content data and store it in its own terminal.

Accordingly, the user can receive and use all of the content data that matches the search keyword regardless of the type of the content data from another mobile communication terminal. For example, if the user sets the search keyword to 'sea', the image is set to 'sea' if the search keyword is matched regardless of the type of content data such as image, music, ringtone, icon, etc. All content data can be downloaded.

In addition, in another embodiment of the present invention, the type of the content data may be set in advance as well as the search keyword of the content data. That is, when the user wants to download only content data having a desired format and not all content data having a search keyword, the type of content data may be selected.

The Bluetooth module 130 forms a Bluetooth connection wirelessly with other Bluetooth modules to enable short-range communication. That is, the Bluetooth module 130 wirelessly establishes a Bluetooth connection with another mobile communication terminal to enable transmission and reception of content data according to the present invention.

In addition, an interface called an HCI (Host Control Interface) is defined between the Bluetooth modules, and a control packet and its result and content data are transmitted and received by exchanging message packets corresponding thereto. The HCI packet is divided into a command, an event, and a data packet. Among them, the command packet provides various commands for variously utilizing the Bluetooth module. Provides a command for.

In addition, the memory 150 connected to the controller 120 includes a read only memory (ROM), a random access memory (RAM), and a voice memory for storing a plurality of programs and information necessary for controlling the operation of the mobile communication terminal. And so on. In addition, according to an embodiment of the present invention, the memory 150 stores various content data such as a ring tone or an image made according to a user's taste so as to be shared with the other party. In addition, under the control of the controller 120, the searched content data may be downloaded and stored in the memory 150.

The user interface 110 includes a plurality of numeric keys and function keys, and outputs input data corresponding to a key selected by the user to the controller 120. This user interface 110 may be a general key matrix or touch screen. When the user interface 110 is implemented as a touch screen, a plurality of numeric keys, function keys, direction keys, etc. displayed on the touch screen may be selected or input by an input tool such as a stylus pen.

Subsequently, the display unit 140 receives and displays display data on key input data input from the user interface 110 under the control of the control unit 120, or displays an operation state and a plurality of information of the mobile communication terminal as icons and text. Display. In addition, the display unit 140 allows the user to visually know the state in setting or driving a required function under the control of the controller 120. Accordingly, the display unit 140 according to an embodiment of the present invention displays a message indicating that there is content data corresponding to the search information input by the user under the control of the controller 120 and a download result of the content data. The display unit 140 may include a liquid crystal display (LCD), a thin film transistor (TFT), an organic electroluminescence (EL), and the like.

As described above, in order to download the content data desired by the user using the Bluetooth module according to the present invention, a Bluetooth module is mounted on each of the master and the slave so as to perform content data transmission and reception using Bluetooth between the master and the slave. do.

Hereinafter, a process for downloading desired content data by searching for desired content data from mobile communication terminals that are slaves in a user terminal, that is, a master terminal, according to an embodiment of the present invention will be described. To this end, reference is made to FIG. 3, which is an operation control flowchart of a master terminal for downloading content data according to an embodiment of the present invention.

First, when the content data search mode is executed, the controller 120 determines whether a search keyword for searching for desired content data is input from the user in step 300. Then, when a search keyword is input, the controller 120 determines whether a type of content data is selected by the user in step 310. If the type of content data is selected in step 310, the controller 120 proceeds to step 320 to generate search information for the content data including the input search keyword and the type of the selected content data, and then executes other mobile communication. Send to the terminal. In this case, the type of content data is for allowing a user to select a format of the content data.

In other words, the controller 120 receives a search condition of content data to be downloaded from the user, generates search information using the same, and transmits the search information to other mobile communication terminals. In this case, the search information is generated according to the Bluetooth standard including a search condition for the content data to be searched. At this time, the other slave terminals are located within a radius of the piconet formed around the master terminal.

In the foregoing description, a search keyword for searching the title of the content data and a type of the content data for selecting the format of the content data as an example of the search are described as an example, so that the user can select not only the search keyword but the type of the content data. In another embodiment of the present invention, only the search keyword may be input to download all kinds of content data matching the search keyword.

On the other hand, in step 320, the transmission of the search information for the content data is possible after the connection (connection) between the master terminal and the slave terminal is established. Accordingly, the master terminal performing the Bluetooth communication first establishes a connection with a slave terminal located within a predetermined distance in order to transmit search information for content data.

Subsequently, a content data search process is performed between the master terminal and the slave terminal to which the connection is established, and when the master terminal transmits the search information to the slave terminal, the slave terminal analyzes the search information and matches the search information. Search for the presence of content data. Then, if there is content data corresponding to the search information, the slave terminal transmits a response message indicating that the searched content data exists to the master terminal.

At this time, if there is no response message received from the slave terminal that has transmitted the search information, the master terminal recognizes that there is no corresponding content data. Therefore, when the master terminal releases the connection and there are a plurality of slave terminals located within the piconet radius, the master terminal performs the above-described procedure on each slave terminal to search whether there is corresponding content data in the slave terminal to which the connection is established.

As such, the master terminal may establish a connection with the slave terminal to download the content data and then download the content data from the corresponding slave terminal through wireless communication of Bluetooth. In addition, after establishing a connection with the plurality of slave terminals, the master terminal may perform a function of sequentially searching for content data and downloading the searched content data.

Accordingly, the control unit 120 of the master terminal side determines in step 330 whether a response message indicating that there is content data corresponding to the search information is received from the slave terminal. In other words, the controller 120 may determine whether there is a terminal for transmitting a response message among other slave terminals in response to transmission of the search information.

As a result of the determination, when there is a received response message, that is, when there is a terminal that transmits the response message, the controller 120 downloads the content data from the terminal that transmitted the response message in step 340, and finds the desired content data. The informing screen is displayed on the display unit 140. An example of such a screen is illustrated in FIG. 5A, and FIG. 5A is a screen example of a screen displayed on a display unit when there is content data searched according to an embodiment of the present invention.

Thereafter, the controller 120 proceeds to step 350 to determine whether the download of the content data is completed, and when the download is completed, stores the downloaded content data in step 360. In this case, as shown in FIG. 5B, if the downloaded content data is an image, a message is displayed asking whether to save the image as a base image. In this way, the user can set the downloaded content data as a wallpaper or a ringtone for each format.

Next, operation control in the slave terminal according to the download of the content data using the Bluetooth method according to the present invention will be described with reference to FIG. 4 is an operation control flowchart of a slave terminal for providing content data according to an embodiment of the present invention.

First, the control unit 120 in the slave terminal receives information through the Bluetooth module from the master terminal in step (400). Then, the controller 120 determines whether the information received in operation 410 is information for requesting content data transmission. If the determination result is the information requesting the transmission of the content data, the control unit 120 searches for content data that satisfies the search information for the content data received in step 420. Accordingly, the controller 120 determines whether there is content data found in operation 430. Then, the control unit 120 transmits a response message indicating that there is the searched content data, and then transmits the content data to the master terminal that requested the search in step 440.

Meanwhile, in the above-described case, if there is found content data, the user may immediately receive desired content data regardless of the intention of the other party. Therefore, according to another embodiment of the present invention, after creating a ringtone or an image of your own and storing it in a space such as, for example, a shared folder, you can set whether or not to share it with others. have. Accordingly, the user can set whether or not to share by designating a folder that can be synchronized, and can prevent the other party from randomly taking content data when the user does not set folder sharing.
