The controller 270 performs overall control of the mobile communication terminal 200 and may include the data processor 220 described above.

In the present embodiment, when there is a request for simultaneous execution of a voice call and a messenger service from the input unit 250, the controller 270 sets a messenger Tx flag in a specific field of the voice call connection signal.

In addition, when a messenger Tx flag is present in a specific field of the voice call connection signal received through the wireless transceiver 210, the controller 270 may allow a user to select a voice call or a simultaneous voice call and messenger service. The menu screen is controlled to be displayed on the display unit 260.

3 is a flowchart illustrating an operation of an originating mobile communication terminal for performing a method of simultaneously executing a voice call and a messenger service according to an embodiment of the present invention.

Referring to FIG. 3, the user of the calling mobile terminal 200a requests simultaneous voice call and messenger service using the input unit 250 (S310). More specifically, the user of the calling mobile terminal 200a selects a hot key provided in the mobile terminal 200a or enters a menu item to select a specific menu for requesting simultaneous voice call and messenger service. By selecting, it requests to perform voice call and messenger simultaneous service.

When there is a request for simultaneous voice call and messenger service from the input unit 250, the controller 270 sets a messenger Tx flag on the voice call connection signal. The controller 270 transmits the voice call connection signal with the messenger Tx flag set to the receiving side mobile communication terminal 200b through the wireless transceiver 210 (S320).

In the present embodiment, setting the messenger Tx flag in the voice call connection signal means setting specific predefined data containing a request to use a messenger service simultaneously with a voice call in a specific field of the voice call connection signal. do.

As such, the voice call connection signal transmitted through the wireless transceiver 210 is transmitted to the receiving mobile communication terminal 200b through the mobile communication network 10.

When the user of the receiving mobile terminal 200b accepts the simultaneous voice call and messenger service request, the receiving mobile terminal 200b sets the messenger Rx flag in a specific field of the ACK signal, which is a response signal, to the mobile communication network. Transmit to the calling mobile terminal 200a through (10).

The control unit 270 of the calling mobile terminal 200a checks whether there is an ACK signal with the messenger Rx flag set among the signals received through the mobile communication network 10.

More specifically, the controller 270 checks whether a messenger Rx flag is set in a specific field of signals received through the mobile communication network 10 and checks whether an ACK signal having a messenger Rx flag is received (S330).

When it is confirmed that the ACK signal set with the messenger Rx flag is received (S330: Y), a message server access signal for automatically connecting to the messenger server 20 is generated. The control unit 270 transmits the generated messenger server access signal to the messenger server 20 through the wireless transceiver 210, whereby the calling mobile terminal 200a connects to the messenger server 20 to log in. It becomes (S350).

At this time, when the receiving side mobile communication terminal 200b is also connected to the messenger server 20 to log in, the calling side mobile communication terminal 200a and the receiving side mobile communication terminal 200b may not only provide a voice call but also a messenger service. It can be done.

4 is a flowchart illustrating an operation process of a receiving side mobile communication terminal for performing a method of simultaneously executing a voice call and a messenger service according to an embodiment of the present invention.

Referring to FIG. 4, the receiving side mobile communication terminal 200b receives a voice call connection signal transmitted from the calling side mobile communication terminal 200a through the wireless transceiver 210 (S410).

The controller 270 of the receiving mobile terminal 200b checks a specific field in the voice call connection signal received from the calling mobile terminal 200a to determine whether the messenger Tx flag is set (S420).

When the messenger Tx flag is set in the received voice call connection signal, the controller 270 recognizes that the user of the calling mobile terminal 200a requests to execute the messenger service simultaneously with the voice call connection request.

As such, when the messenger Tx flag is set in the received voice call connection signal (S430: Y), the controller 270 displays a menu screen on the display unit 260 for selecting types of voice calls and messenger services. It is controlled to (S440).

5 is a menu screen for selecting types of voice calls and messenger services according to an embodiment of the present invention.

Referring to FIG. 5, the menu screen 500 includes a first 'call + messenger' menu, a second 'call' menu, and a third 'end' menu.

The user of the receiving mobile communication terminal 200b may select the first 'call + messenger' menu to communicate with the user of the calling mobile communication terminal 200a using a messenger as well as a voice call. In addition, the user may select the second 'voice call' menu when only the voice call is desired. In addition, if not even a voice call, the user may select the 'end' menu three times.

When the user of the receiving mobile terminal 200b selects the 'call + messenger' menu No. 1 (S450: Y), the controller 270 sends a message in a specific field of the ACK signal, which is a response signal for the voice call connection signal. The Rx flag is set to generate an ACK signal in which the messenger Rx flag is set (S460).

In addition, when the user of the receiving-side mobile communication terminal 200b selects the 'call + messenger' menu No. 1 (S450: Y), the controller 270 generates a messenger server access signal for accessing the messenger server (S470). ).

The controller 270 transmits the generated ACK signal to the calling mobile terminal 200a and simultaneously transmits a messenger server access signal to the messenger server 20 through the wireless transceiver 210 (S480).

As a result, the receiving mobile terminal 200b performs a voice call with the calling mobile terminal 200a and simultaneously connects to the messenger server 20 to log in. The receiving mobile terminal 200a and the messenger service are connected. It becomes possible to use (S490).

In addition, when the calling mobile terminal 200a receives the ACK signal with the messenger Rx flag set, the calling mobile terminal 200a receives the simultaneous execution request for the voice call and the messenger service. ) To be accepted.

In the above-described embodiment, when the user selects the 'call' menu twice, the controller 270 of the receiving-side mobile communication terminal 200b transmits an ACK signal without setting the messenger Rx flag. In this case, only the voice call is executed between the calling mobile terminal 200a and the receiving mobile terminal 200b.

In the above description of the preferred embodiment of the present invention, the present invention is not limited to the above-described specific embodiment, it is common in the art to which the invention belongs without departing from the spirit of the invention claimed in the claims. Various modifications can be made by those skilled in the art, and such changes are within the scope of the claims.

As described above, according to an embodiment of the present invention, the users of the mobile communication terminal has an advantage that can communicate with each other using a messenger service at the same time the voice call is connected. Therefore, as in the related art, there is an advantage in that the user can avoid the hassle of using a messenger service through a separate dedicated key or menu operation during a voice call.
