In FIG. 5B, only the system divided up and down is illustrated, but the present invention is not limited to the system. Meanwhile, when the two divided regions are referred to as the first region 501 and the second region 502 from the bottom, respectively, the first region 501 and the second region 502 may be colored, bordered, Areas can be distinguished in various ways, including in various shapes.

In operation S140, the touch screen of the mobile terminal 100 displays information on the first call and information on the second call on each of the divided first and second areas.

For example, in the first area 501 of the first call connection state, various information such as current call state information, the name of the other party of the first call, a phone number, a picture, a call connection time, and the like may be displayed. In addition, the second area 502 of the second call currently in the call waiting state may display various information such as current call state information, the name of the other party of the second call, a phone number, and call waiting time.

In operation S150, the mobile terminal 100 receives a touch drag operation from the user through the touch screen.

The mobile terminal 100 may receive various touch drag operations from the user on the touch screen. For example, the user may input a touch drag gesture having a constant drag distance in one direction from various positions on the touch screen, a touch drag gesture in various directions, or a touch drag gesture at various speeds. In addition, a touch drag operation having various times may be input.

The present invention has been described with reference to a touch drag operation pattern having a certain drag distance and a touch drag operation pattern having a predetermined number of times starting from a specific region among the touch drag operation patterns, but the present invention is not limited thereto. Can be included.

For example, the pattern according to the difference in the speed of the touch drag operation, the pattern according to the defined various directions of the touch drag operation (for example, upward, downward, leftward, rightward direction, etc.), the specified specific form of the touch drag operation, and the like. Various touch drag gesture patterns such as patterns may be included in the present invention.

In operation S160, when a prescribed touch drag action pattern exists among various touch drag actions of the user, the controller 180 analyzes the pattern of the touch drag action.

6A to 6E, a first embodiment of a touch drag operation pattern will be described.

As an embodiment of the present disclosure, when the starting point of the touch drag operation is started in the second area 502, the controller 180 may classify and analyze the pattern of the touch drag operation as follows.

(1) When the touch drag operation reaches the left and right boundaries of the touch screen display area (FIG. 6A), (2) When the end of the touch drag is the first call control area 601 (FIG. 6B), (3) Touch drag When the end point of the second call control area 602 is (FIG. 6C) and (4) the end point of the touch drag is the third call control area 603 (FIG. 6D), the controller 180 divides and analyzes. do. Here, the call control area means a specific area having a predetermined area in the first area 501. When the end point of the touch drag operation is each call control area, the controller 180 analyzes the motion pattern accordingly. After that, set the call status. In the present specification, for example, the first call control area 601 is 45 to 65% area from the top of the touch screen display area, and the second call control area 602 is 65 to 85% from the top of the touch screen display area. The area, the third call control area 603, may be an 85% or more area. The above figures are exemplary, and the present invention may define the call control area in various values. In addition, the setting of the call control area can be made in various ways and is not limited to the above embodiment.

The mobile terminal of the present invention can visually clearly show that belonging to each call control area on the touch screen. For example, when the end point of the touch drag operation belongs to the first call control area 601, the boundary line between the two areas may be located about 50% from the top of the display area of the touch screen. In addition, when the touch drag operation end point belongs to the second call control area 602, the boundary line may be located about 75% from the top of the display area of the touch screen. In addition, when the end point of the touch drag operation belongs to the third call control area 603, the boundary line may be located at the bottom of the display area of the touch screen. By doing so, the present invention can make the end of the touch drag operation belong to each call control area so that the user can clearly recognize the call state setting.

In operation S170, the controller 180 sets a call state according to the touch drag operation pattern analyzed in operation S160. Here, the touch screen displays the call state of each call according to the call state setting of the controller.

6A to 6D are diagrams illustrating a call state according to a touch drag operation pattern according to an embodiment of the present invention.

Referring to FIG. 6A, the call drag operation is started in the second area 502 to indicate a call state when the touch drag operation reaches the left and right boundary of the display area of the touch screen ((b) of FIG. 6A). Although the figure shows only the case to the right outside, the case to the left outside is also included in the present invention. In this case, the controller 180 terminates the call state of the second call and maintains the call state of the first call in a call connection state. In Fig. 6A (c), the existing call is maintained and the newly received call is terminated. According to a setting signal of the controller 180, the touch screen provides only information of a call that is currently connected to a call. In (c) of FIG. 6A, the touch screen displays information of the first call, which is a call currently connected to an existing call.

In FIG. 6C (c), the touch screen shows the first area 501 and the second area 502, which are mutually changed in size, and the touch screen displays the current call state information in the second area 502, of the second call. Information on the other party's name, phone number, picture, call connection time, and the like is shown, and information on the current call state information, name of the first party's name, phone number, picture, waiting time and the like is displayed on the first area 501.

 According to another embodiment of the present invention, when the call state is mutually changed in accordance with the change setting of the call state of the first call and the second call, the call state of the second call and the first call may be reversely changed. For example, the call state is changed and set when the touch drag operation is started in the first area 501 and the end points of the touch drag operation are the call control areas of the second area 502. The controller 180 may change and set the call state according to the first call back to the call connection state and change and set the call state according to the second call to the call waiting state. Here, the call control areas of the second area 502 can be set similarly to the call control areas 601, 602, and 603 in the first area, having a certain area from the top of the second area 502. It may be a specific area.

Referring to FIG. 6D, the touch drag operation is started in the second area 502 and the call drag operation is shown in the case where the end point of the touch drag operation is the third call control area 603 ((b) of FIG. 6D). As the touch drag operation proceeds, the boundary between the first area 501 and the second area 502 is moved according to the degree of the touch drag operation. The controller 180 may terminate the call state by the first call and set the call state by the second call to the call connection state. In FIG. 6D (c), the touch screen displays information on the second call on the touch screen display area according to a setting signal of the controller. For example, the information on the second call may include current call state information, the name of the other party of the second call, a phone number, a picture, a connection time, and the like.

6E illustrates another embodiment for setting a call state to a conference call connection state. When the user rotates clockwise while touching two points on the touch screen using two pointers (see (b) of FIG. 6E), the controller 180 sets the call state to the conference call connection state. . For example, the other party of the first call, the second party of the newly received second party, and the user of the mobile terminal of the present invention are in a state of talking together. According to the setting signal of the controller 180, the touch screen provides information related to the conference call to the display area. In FIG. 6E (c), the touch screen displays information related to the conference call. For example, the information related to the conference call may provide current call state information, names of participants in the conference, connection time of the conference, photos of the participants, phone numbers of the participants, and the like. In addition, although not shown in the drawings, rotation in the counterclockwise direction is also included in the present invention.

Returning to step S160, when the mobile terminal receives another touch drag operation pattern defined during various touch drag operations of the user, the controller analyzes the pattern of the touch drag operation.

With reference to FIGS. 7A-7D, a second embodiment of a touch drag operation pattern will be described.

According to the second embodiment of the present invention, the touch drag operation pattern may be analyzed according to the number of touch drag operations. In this case, the controller 180 can classify and analyze as follows.

In operation S170, the controller 180 sets a call state according to the touch drag operation pattern analyzed in operation S160. Here, the touch screen displays the call state of each call according to the call state setting of the controller.

7A to 7D are diagrams illustrating a call state according to a touch drag operation pattern according to a second embodiment of the present invention.

Referring to FIG. 7A, the call drag operation is started in the second area 502 to indicate a call state when the touch drag operation reaches the left and right boundary lines of the touch screen display area (FIG. 7A (b)). In this case, the controller 180 terminates the call state of the second call and sets the call state of the first call to the call connection state. Retains the existing connecting call and terminates the newly received call. According to the setting signal of the controller, the touch screen provides only the information of the existing call connection. In FIG. 7A (c), the touch screen displays information of the first call, which is the call currently being connected. For example, the information of the first call includes current call state information, the name of the other party of the first call, a phone number, a picture, a connection time, and the like.

Referring to FIG. 7B, a call state is shown when a touch drag operation is given once. In FIG. 7B (b), the touch screen indicates with one arrow that a touch drag operation is given once. In this case, the controller 180 sets the call state to the conference call connection state. For example, the other party of the first call, the second party of the newly received second party, and the user of the mobile terminal of the present invention are in a state of talking together. According to a setting signal of the controller, the touch screen provides information related to the conference call to the display area. In FIG. 7B (c), the touch screen displays information related to the conference call. For example, the information related to the conference call may provide current call state information, names of participants in the conference, connection time of the conference, photos of the participants, phone numbers of the participants, and the like.

Referring to FIG. 7C, a call state is shown when two touch drag operations are given. In FIG. 7C (b), the touch screen indicates by two arrows that the long touch drag operation has been given twice. In this case, the controller sets the call state according to the first call to a call waiting state and sets the call state according to the second call to a call connection state. In FIG. 7C (c), the touch screen shows the first area 501 and the second area 502 which are mutually changed in size, and the touch screen shows the current call state information in the second area 502 of the second call. Information on the other party's name, phone number, picture, call connection time, and the like is shown, and information on the current call state information, name of the first party's name, phone number, picture, waiting time and the like is displayed on the first area 501.

Referring to FIG. 7D, a call state is shown when a touch drag operation is given three times long. In FIG. 7D (b), the touch screen indicates with three arrows that the long touch drag operation has been given three times. The controller 180 may terminate the call state by the first call and set the call state by the second call to the call connection state. In (c) of FIG. 7D, the touch screen displays information on the second call in the display area according to a setting signal of the controller. For example, the information on the second call may include current call state information, the name of the other party of the second call, a phone number, a picture, a connection time, and the like.

Meanwhile, when the controller 180 sets the call state, the mobile terminal of the present invention may output the setting notification of the call state through the output unit 150. For example, when terminating the call state by the first call and setting the call state by the second call as the call connection state, the haptic module 154 may generate minute vibration. In addition, the present invention is not limited to the vibration method of the output method, it is also possible to apply a variety of output methods such as using audio, text, images, animation, video, icons, and the like.

According to another embodiment of the present invention, although not shown in the figure, the present invention can be applied even when the conference call connection state is ongoing. For example, the present invention can be applied even when there is a newly received call by a third party C during a conference call with A, B, etc. through the mobile terminal of the present invention. Accordingly, the touch screen of the present invention may be divided into a first area and a second area, designate the first area as a conference call area, and designate the second area as a newly received call. In this case, when receiving a prescribed touch drag operation pattern of the user, the controller may change and set each call state.

8A to 8C illustrate a configuration when a new call is attempted during a conference call according to another embodiment of the present invention. When there is a touch drag operation from the top to the bottom by the user during the conference call, the area boundary line is moved accordingly (FIG. 8A (b)) . In this case, the touch screen displays two areas in the display area of the display unit 151, and the first area 801 displays an indication of “adding a conference call” asking whether to try a new call and join the conference. The second area 802 displays an indication of “new call” asking whether to try a new call that is not related to the conference call (FIG. 8A (c)).

8B and 8C illustrate a case in which a mobile terminal is selected by touching the area from a user.

Referring to FIG. 8B, the user selects by touching “add conference call”. If the user selects “add conference call”, the touch screen displays the dial pad in the display area (FIG. 8B (b)). When the user inputs a new participant's phone number through the dial pad, the user sends a call to the new participant through the mobile communication module 113 of the wireless communication unit. When the call is connected, the controller 180 adds a new participant to the existing conference call, and the touch screen displays information of the new participant in addition to the existing conference participant in the display area (FIG. 8B (c)).

Referring to FIG. 8C, the user selects a new call by touching it. When the user selects "New Call", the touch screen displays the dial pad on the display area (Fig. 8C (b)) When the user enters a new party's telephone number through the dial pad, the wireless communication unit moves. The call is sent to the new participant through the communication module 113. When the call is connected, the controller 180 sets the call state of the existing conference call to the call waiting state, and sets the call state of the new call to the call connection state. In addition, the touch screen divides the display area into two areas and displays information on each call state in each area (FIG. 8C (c)).

Meanwhile, when the display area of the touch screen is divided into areas, the mobile terminal of the present invention may provide a visual quee indicating that the area of the area can be changed by changing the boundary line of each area. .
