In the case of being touched together, there may be a case where the user clamps the terminal body using the thumb and index finger. The one function may be activation or deactivation of the display unit 151 or the touch pad 135, for example.

Hereinafter, a call control method according to the present invention will be described in more detail with reference to the accompanying drawings.

For convenience of explanation, it is assumed that the mobile terminal receives the second call during the call connection according to the first call.

FIG. 4 is a flowchart of a control method when a second call is received during a first call connection of the mobile terminal according to the present invention, and FIGS. 5 to 8C illustrate a method of controlling a call control method of the mobile terminal and the mobile terminal according to the present invention. FIG. 2 is a state diagram of a display screen on which a form is implemented.

Referring to the flowchart of FIG. 4, in step S110, the mobile terminal 100 receives the second call during the call connection by the first call using the wireless communication unit 110. [

It is assumed that the mobile terminal 100 and the first party are in a first call. That is, a call connection for the first call is established between the mobile terminal 100 and the first counterpart terminal. In this case, the second party tries to make a second call to the mobile terminal 100. That is, the second party transmits a call request signal for the second call to the mobile terminal 100. Then, the mobile terminal 100 receives the call request signal through the mobile communication module 113 of the wireless communication unit 110 or the like.

In step S120, the controller 180 of the mobile terminal 100 sets the call state of the first call in the call connection state to the call connection state and sets the call state of the newly received second call in the call waiting state.

As used herein, the term "call connection state" means a state in which a user of a mobile terminal and a user of a counterpart terminal make a voice or video call while a two-way call is connected to the mobile terminal 100. Meanwhile, the term "call waiting state" means a state in which a two-way call is connected to the mobile terminal 100, or a user of the mobile terminal 100 is connected to a user of another terminal and waits for a call.

If a new call is received in step S110, the mobile terminal of the present invention needs to distinguish between a call that is in the current call and a call that is newly received. therefore, In step S120, the control unit 180 sets the call state of the first call in the existing call state to the call connection state, and sets the call state of the newly received second call in the call waiting state.

In step S130, the touch screen of the mobile terminal 100 divides the display area of the touch screen into first and second areas under the control of the controller 180. [

5, when the mobile terminal 100 receives a second call during a call by the first call (FIG. 5A), the touch screen displays the display area of the display unit 151 in the first area (501) and the second area 502 (Fig. 5 (b)).

In this case, the touch screen divides the display area of the display unit 151 at a predetermined ratio. For example, the display area can be divided in various ways such as up / down or left / right at various ratios such as 2: 8, 3: 7, 4: 6. In FIG. 5B, only the upper and lower divided systems are shown, but the present invention is not limited to this system. When two divided regions are referred to as a first region 501 and a second region 502 from the bottom, respectively, the first region 501 and the second region 502 may be color, It is possible to distinguish areas in various ways such as various shapes.

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

For example, in the first area 501 of the first call connection state, various information such as the current call state information, the name of the other party of the first call, a telephone number, a photograph, and a call connection time can be displayed. In addition, the second area 502 of the second call, which is currently in the call waiting state, can display various information such as the current call state information, the name of the other party of the second call, the telephone number, and the call waiting time.

In step S150, the mobile terminal 100 receives the 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 can input a touch drag operation having a predetermined drag distance in one direction at various positions on the touch screen, input a touch drag operation in various directions, or input a touch drag operation at various speeds, Also, it is possible to input a touch drag operation having various times.
