3 is a front view of a mobile terminal for explaining an operation state of the mobile terminal according to the present invention.

Various types of time information can be displayed on the display unit 151. [ These pieces of information can be displayed in the form of letters, numbers, symbols, graphics, or icons.

At least one of the letters, numbers, symbols, graphics, or icons may be displayed in a predetermined arrangement for inputting such information, thereby being implemented as a keypad. Such a keypad may be called a so-called " soft key ".

3 illustrates receiving a touch applied to a softkey through the front of the terminal body.

The display unit 151 may operate in an entire area or may be operated in a divided manner. In the latter case, the plurality of areas can be configured to operate in association with each other.

For example, an output window 151a and an input window 151b are displayed on the upper and lower portions of the display unit 151, respectively.

4 is an example illustrating a Bluetooth function setting procedure of a mobile terminal according to an embodiment of the present invention.

Prior to using the Bluetooth function, the user activates the Bluetooth function of the mobile terminal 100. The controller 180 of the mobile terminal 100 sets or releases a Bluetooth function according to a user input.

For example, when the user manipulates the user input unit 130 and selects a Bluetooth menu among the menus, the controller 180 enters a Bluetooth menu for performing Bluetooth setting / release and device addition and registration according to the user input. . When the controller 180 enters the Bluetooth menu, the controller 180 displays a Bluetooth management screen on the display unit 151. The Bluetooth management screen is divided into a status display area 210 for displaying a state of a terminal and an information display area 220 for displaying information. The status display area 210 displays whether the Bluetooth is set, whether the Bluetooth device is connected, the signal strength, whether the message is received, whether the alarm is set, the battery remaining amount, and the time. The information display area 220 displays a result according to the operation of the terminal and information output according to the progress. That is, the management screen is displayed on the information display area 220.

When the Bluetooth setting / release toggle icon is selected on the management screen, the controller 180 activates or deactivates the Bluetooth function according to the selection input. For example, when the Bluetooth on / off toggle icon is touched, the sensing unit 140 detects the touch and transmits a control signal corresponding thereto to the controller 180. The controller 180 alternately sets the Bluetooth setting and the release each time the control signal is input. In other words, when a touch is detected on the Bluetooth on / off toggle icon while the Bluetooth function is inactive, the controller 180 switches the Bluetooth function to an active state. Subsequently, when a touch is again detected on the Bluetooth setting / release toggle icon, the controller 180 switches the Bluetooth function from an active state to an inactive state.

In addition, when the Bluetooth function is activated, the controller 180 displays a Bluetooth indicator 230 indicating that the Bluetooth is in use in the status display area 210. Meanwhile, when the Bluetooth function is inactivated, the controller 180 causes the Bluetooth indicator 230 displayed on the status display area of the display screen to disappear.

Hereinafter, a case in which the Bluetooth function of the mobile terminal 100 is active will be described as an example.

5 is a flowchart illustrating a data transmission method of a mobile terminal according to an embodiment of the present invention.

Referring to FIG. 5, when a specific event occurs, the controller 180 executes a specific function according to the generated event and displays an execution screen (hereinafter, a specific function screen) of the specific function on the display unit 151 ( S101). In this case, the specific event includes user input and message reception. The specific function includes a phone book, calendar / scheduler, message, memo, music (sound source), video, image, and the like.

When a drag input occurs on the display screen displaying the specific function screen, the sensing unit 140 detects the drag input and transmits a control signal corresponding thereto to the controller 180 (S102). For example, when a touch is detected at a first point on a specific function screen, the controller 180 selects specific data corresponding to the touch point. The specific data may be all or part of data currently displayed on the display screen. Then, if the touch is released after the touch point is moved to the second point while the touch is maintained, the sensing unit 140 detects this and notifies the controller 180.

The controller 180 checks whether the point at which the drag input is released overlaps with the Bluetooth indicator (S103). For example, the controller 180 checks whether the second point where the touch is released is on the Bluetooth indicator.

When the drag input is released on the Bluetooth indicator, the controller 180 searches for a Bluetooth device located nearby (S104). The controller 180 transmits an inquiry signal in the form of a broadcast through the short-range communication module 114 previously driven. Thereafter, the controller 180 receives the response signal of the peripheral device in response to the inquiry signal and searches for the peripheral Bluetooth device (wireless device). This search operation may proceed in the background.

When the Bluetooth device is found, the controller 180 displays a list of the found Bluetooth devices (S105). Here, the controller 180 displays the device name and device type of the found Bluetooth device.

If at least one device from the searched Bluetooth device list is selected, the controller 180 performs a connection setup with the selected device (S106).

When the connection setting is completed, the controller 180 transmits the information displayed on the specific function execution screen to the selected Bluetooth device (S107). Here, the information may be data selected by the user or data being executed.

On the other hand, if the drag is not released from the Bluetooth icon in step S103, the controller 180 performs an input by the input drag (S108). For example, if a drag is input while displaying one of the photos registered in the album by executing the album function, the controller 180 displays the previous picture or the next picture based on the picture list according to the drag input.

The controller 180 executes the multimedia player and displays a music playback screen on the display screen (c). The controller 180 can sequentially play the sound sources registered in the play list in a predetermined order or play only the selected specific sound source.

The controller 180 transmits the reproduced sound source to the headset through the short range communication module 114. In this case, the controller 180 displays the indicator 240 according to the currently connected Bluetooth device on the display screen. In other words, the controller 180 displays an indicator 240 indicating the type of the currently connected Bluetooth device.

8 illustrates an example of transmitting a sound source to be reproduced by a mobile terminal according to an embodiment of the present invention and transmitting the sound source to another device.

The controller 180 controls the multimedia module 181 to play the sound sources in the playlist. The controller 180 transmits the playback sound source output from the multimedia module 181 to another device through the short range communication module 114. For example, the controller 180 transmits the reproduced sound source to the headset, and the headset outputs the received sound source to the outside.

If at least one sound source in the playlist is selected according to a user input while transmitting the reproduced sound source to the headset, and the selected sound source is dragged to the Bluetooth indicator 230, the controller 180 may perform the sensing unit 140. Detect drag input. For example, when a long touch is input to any one item of a playlist, the controller 1800 recognizes that the item is selected.

Also, when the drag is released on the Bluetooth indicator 230, the controller 180 searches for a Bluetooth device located nearby. In this case, the Bluetooth device currently connected to the mobile terminal 100 may be excluded from the search. The controller 180 displays a list of the found Bluetooth devices.

When any one of the searched Bluetooth devices is selected, the controller 180 transmits the selected sound source to the selected device.
