Description of the Related Art In recent years, communication terminals have been able to simultaneously perform a video communication function and a data communication service function, in particular, a data communication service in a packet service format, while evolving into a 3G (Generation) WCDMA (Wideband Code Division Multiple Access) environment. Accordingly, when receiving a video call while performing a data communication service, a received video call can be connected while performing a data communication service. Alternatively, the data communication service can be performed while the video call is connected.

However, when the video call function and the data communication service are performed at the same time, the network load may be caused and the video call or data communication service may not be performed smoothly.

An object of the present invention is to provide a communication terminal capable of effectively performing a video call function and a data communication service and a method of controlling the operation thereof.

Also, the communication terminal can store the identification information of the video call received in the receiving step (S620) in the memory (160). Here, the identification information may include a telephone number, a name set in the telephone number, a reception time, and the like.

In step S620, the communication terminal 100 determines whether there is data to be transmitted to or received from the network using the data communication service in the connection step S610 S630).

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

Herein, a state in which there is no data transmitted / received through a traffic channel for a predetermined time while the network and the data communication service are connected may be referred to as a preservation state.

Therefore, the communication terminal 100 can determine whether it is in the current reservation state in the determination step (S630).

The communication terminal 100 may reject the video call received in the receiving step S620 in operation S640. If there is data to be transmitted / received, the communication terminal 100 may reject the video call received in operation S620.

The rejection step S640 will now be described with reference to FIG. 7A. When the communication terminal 100 receives the video call from the second communication terminal 510 (S707) The call can be rejected (S709). This is because, even if a video call is received, it can be assumed that the current user desires to transmit / receive data using the data communication service.

Of course, although not shown in the drawing, even when the mobile terminal is not in the pre-reservation state, it can 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 video call and data communication service at the same time or only one of them.

Then, the communication terminal 100 can notify that the video call is rejected through the output unit 150 as the video call is rejected in the rejecting step (S640) (S650).

If it is determined that there is no data to be transmitted or received (or in the case of the pre-reservation state), the communication terminal 100 receives the video call in the receiving step S620 and is connected in the connecting step S610 The data communication service can be terminated (S660).

7B, the communication terminal 100 is judged to be in a state of being in the pre-presence state when receiving the video call from the second communication terminal 510, (S710). As a result, the data communication service with the network 520 can be terminated (S712). This is because, when the video call is received, it can be assumed that the user is no longer willing to use the data communication service.

The communication terminal 100 can connect the video call received in the receiving 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 the video call from the second communication terminal 510 (S708) (S714). As a result, the video call can be connected to the second communication terminal 510 (S716).

Of course, although not shown in the drawings, the video call may be rejected or the data communication service may not be terminated, depending on the user's selection, even in the case of a pre-reservation state. That is, the user may select whether to connect video call and data communication service at the same time or only one of them.

In step S660, the communication terminal 100 can notify that the data communication service is terminated through the output unit 150 as the data communication service is terminated in step S660.

Hereinafter, with reference to FIG. 8A to FIG. 8E, a screen configuration at the time of receiving a video call will be described in a case where it is not in the pre-reservation state.

The communication terminal 100 can receive a video call while downloading data using the data communication service (Fig. 8A) (Fig. 8B).

The communication terminal 100 can request the user to reject the video call because the communication terminal 100 is not currently in a state of being in the reservation state (FIG. 8C).

Of course, if the communication terminal 100 determines that the video call is not in a state of being in a reservation state when receiving a video call, the video call can be rejected irrespective of whether the user selects the video call.

When the video call rejection ("Yes") is selected in FIG. 8C, the communication terminal 100 can output a message informing that the video call is rejected because the data communication service is being performed (FIG.

8D is selected, the communication terminal 100 can display the rejected video call identification information (e.g., telephone number, setting name, receiving time, etc.) on the screen (Fig. 8E).

Alternatively, the communication terminal 100 can store the identification information of the rejected video call in the memory 160, and when the "telephone record inquiry" function is selected by the user in the future, Can be displayed. Alternatively, it may be displayed together with an indicator indicating that the video call is rejected in the data communication service.

Hereinafter, with reference to Figs. 9A to 9D, the screen configuration at the time of receiving a video call in the case of the pre-reservation state will be described.

The communication terminal 100 can request the user to terminate the data communication service since the video communication terminal 100 is in the state of being in the pre-reservation state (FIG. 9A) when the video call is received in a state where there is no data transmitted / .

Of course, the communication terminal 100 can end the data communication service irrespective of whether or not the user selects it, when the video communication terminal 100 is judged to be in the state of being in the reservation state when receiving the video call.

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

Then, the communication terminal 100 can display the user image and the internal image according to the connection of the video call on the screen (Fig. 9D).

Further, according to the embodiment of the present invention, the above-described operation control method can be implemented as a computer-readable code on a medium on which a program is recorded. The computer readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of the computer-readable medium include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, and also implemented in the form of a carrier wave (for example, transmission over the Internet) . In addition, the computer may include a control unit 180 of the communication terminal 100. [
