In addition, the communication terminal may store the identification information of the video call received in the reception step S620 in the memory 160. Here, the identification information may include a telephone number, a name set for the telephone number, a reception time, and the like.

In addition, as the communication terminal 100 receives the video call in the reception step S620, the communication terminal 100 determines whether there is data transmitted / received between the network and the network using the data communication service connected in the connection step S610 ( S630).

In the determination step (S630), the communication terminal 100 may determine whether there is data transmitted / received for a predetermined period (for example, 1 minute, 10 minutes, 30 minutes) by using a data communication service. have.

Herein, a state in which data transmitted / received through a traffic channel for a predetermined time while a network and a data communication service are connected may be referred to as a preservation state.

Therefore, the communication terminal 100 may determine whether it is in a preservation state at step S630.

If there is data to be transmitted and received as a result of the determination (or not in the preservation state), the communication terminal 100 may reject the video call received in the reception step S620 (S640).

Referring to FIG. 7A, the rejection step (S640) will be described. When the communication terminal 100 receives a video call from the second communication terminal 510 (S707), it is determined that it is not in a preservation state. The call may be rejected (S709). This is because even if a video call is received, it can be assumed that the current user wants to transmit and receive data using a data communication service.

Of course, although not shown in the figure, even if the state is not in the preservation state, it is possible to connect the received video call or terminate the connection of the data communication service according to the user's selection. That is, the user may select whether to connect the video call and the data communication service at the same time or only one of the two.

In addition, as the video call is rejected in the rejection step (S640), the communication terminal 100 may notify that the video call is rejected through the output unit 150 (S650).

On the other hand, if there is no data transmitted or received as a result of the determination (or in the preservation state), the communication terminal 100 receives the video call in the reception step (S620), connected in the connection step (S610) The data communication service may be terminated (S660).

Referring to FIG. 7B, the termination step S660 is described. When the communication terminal 100 receives a video call from the second communication terminal 510, the communication terminal 100 determines that it is in a preservation state. The connection request of the communication service may be stopped (S710), and as a result, the data communication service with the network 520 may be terminated (S712). This is because the user can no longer use the data communication service if he is in the preservation state when receiving the video call.

In addition, the communication terminal 100 may connect the video call received in the reception step S620 through the wireless communication unit 110, in particular, the mobile communication module 112 (S670).

Referring to FIG. 7B, the connection step S670 will be described. When the communication terminal 100 receives a video call from the second communication terminal 510 (S708), the communication terminal 100 determines that the video call is in a preservation state. In operation S714, as a result, the second communication terminal 510 may be connected to the video call in operation S716.

Of course, although not shown in the figure, even in the preservation state, the video call may be rejected or the data communication service may not be terminated according to the user's selection. That is, the user may select whether to connect the video call and the data communication service at the same time or only one of the two.

In addition, as the data communication service is terminated in the termination step S660, the communication terminal 100 may notify that the data communication service is terminated through the output unit 150 (S680).

Hereinafter, with reference to FIGS. 8A to 8E, the screen configuration when receiving a video call when not in a preservation state will be described.

The communication terminal 100 may receive a video call while downloading data using a data communication service (FIG. 8A) (FIG. 8B).

Since the communication terminal 100 is not currently in a preservation state, the communication terminal 100 may request the user whether to reject the video call (FIG. 8C).

Of course, if it is determined that the communication terminal 100 is not in a preservation state when receiving the video call, the communication terminal 100 may reject the video call regardless of whether the user selects it. Therefore, the screen of FIG. 8C is not necessarily required.

When the rejection of the video call (“Yes”) is selected in FIG. 8C, the communication terminal 100 may output a text indicating that the video call was rejected because the data communication service is being performed (FIG. 8D).

When the "confirmation" area of FIG. 8D is selected, the communication terminal 100 can display identification information (eg, a phone number, a setting name, a reception time ...) of the rejected video call on the screen. (FIG. 8E).

Alternatively, the communication terminal 100 may store the identification information of the rejected video call in the memory 160, and the identification information of the rejected video call as a missed call when the user selects the "call record check" function later. Can be displayed. Alternatively, the display may be displayed together with an indicator indicating that the video call is rejected during the data communication service.

Hereinafter, with reference to FIGS. 9A to 9D, a screen configuration when receiving a video call in the preservation state will be described.

If the communication terminal 100 receives a video call in a state in which there is no data transmitted or received for a predetermined time (FIG. 9A), the communication terminal 100 may request the user whether to terminate the data communication service because it is in a preservation state (FIG. 9B). .

Of course, if it is determined that the communication terminal 100 is in a preservation state when receiving a video call, the communication terminal 100 may terminate the data communication service regardless of whether the user selects it.

When the end of the data communication service (“Yes”) is selected in FIG. 9B, the communication terminal 100 may output a phrase indicating that the data communication service is terminated in order to receive a video call (FIG. 9C).

In addition, the communication terminal 100 may display a user image and an inner image according to the connection of the video call on the screen (FIG. 9D).
