Hereinafter, referring to FIG. 3, a method of transmitting and receiving data in a mobile communication terminal device according to an embodiment of the present invention will be described in detail.

3 is a flowchart illustrating a data transmission and reception method in an embodiment of a mobile communication terminal according to the present invention.

As shown, in the data transmission and reception method according to the present invention, the transmitting terminal A and the receiving terminal B participate. First, the receiving terminal B is designated by the transmitting terminal A (S2). Before that, both terminals are synchronized via a messenger program or connected to each other via a video call. Alternatively, after designating the receiving terminal, synchronization may be performed (S4). In this state in which the transmitting terminal A and the receiving terminal B are synchronized, the user of the transmitting terminal A selects an image file to be transmitted (S6). Next, the user of the transmission terminal generates a transmission command signal using the user input unit (S8). Then, the control unit of the transmitting terminal generates a preview file of the selected file. For example, if the selected file is a still image file, a thumbnail image is generated. Alternatively, if the selected image is a moving image image file, a video clip file or a captured image is generated. If the selected file is not an image file, a summary file is generated using the additional information of the file. Next, the control unit of the transmitting terminal transmits the preview file generated through the wireless communication unit to the receiving terminal (S12). The control unit of the receiving terminal displays the preview file received through the wireless communication unit on the display unit, and accordingly, the receiving terminal user checks the received preview file (S14). The controller of the receiving terminal checks the type of the original file from the preview file, and confirms whether the file is supported by the receiving terminal (S16). The control unit of the receiving terminal transmits a supportable notification signal indicating whether the support is possible to the transmitting terminal (S18). If the transmitting terminal receives the non-supportable notification signal of the unsupportable file in the receiving terminal, the selected image file is displayed to be distinguished from other image files (S20). On the other hand, if the user of the receiving terminal generates the transmission request signal after checking the preview file, the transmission request signal is transmitted to the transmitting terminal through the wireless communication unit of the receiving terminal (S22). In accordance with this transmission request signal, the original image file is transmitted from the transmitting terminal to the receiving terminal (S24). At this time, if the image file is not supported by the receiving terminal, the control unit of the receiving terminal converts the image file into a supportable file (S26).

In the present embodiment, when a relatively large size data such as an image file is transmitted / received during an instant message or a video call, only the preview file is transmitted first. By doing so, the user can select and transmit only the desired data.

Hereinafter, a mobile communication terminal to which a data transmission / reception method is applied in the mobile communication terminal will be described in detail with reference to FIGS. 4 and 5.

When one image (at least one image) 221 is displayed on the photo album menu screen 220 displayed as the plurality of thumbnails, the controller 180 generates a thumbnail image of the image (may be generated in advance). The thumbnail image is transmitted to the receiving terminal through the wireless communication unit. In addition, the display unit 151 may display a thumbnail transmission notification window 230 indicating this (see FIG. 4D).

Then, upon receiving the original image file transmission request from the receiving terminal, the original image file transmission notification window 240 notifying the original image file is transmitted to the receiving terminal and notifying the display of the original image file (see FIG. 4E). ). The transmission notification window 240 may include a transmission progressive bar 241 indicating the transmission degree of the original image.

On the other hand, although not shown, when receiving a signal that the reproduction of the original image file from the receiving terminal, it can be displayed to distinguish the image file from other files.

In the present embodiment, an example of transmitting a thumbnail image as a preview image of a still image has been described. However, the present invention is not limited thereto. In the case of a video image, a captured image or a video clip image is transmitted in advance, or a general file is summarized using additional information. You can also create an information file and transfer it.

In addition, in the present embodiment, an example of transmitting an image file while executing an instant message service has been described. However, the present invention may be applied to data transmission during video call and data transmission during voice call.

Second Application Example

5 is an image illustrating a second application example of a mobile communication terminal to which a data transmission / reception method is applied in a mobile communication terminal according to an embodiment of the present invention.

In FIG. 5, a method of transmitting and receiving data at a receiving terminal will be described.

5A shows an instant message screen 300. On this instant message screen, a display window 301, an input window 302, a menu icon 303, a transfer icon 304, and a telephone book icon 305 are displayed.

In this state, when the preview image file transmitted from the transmitting terminal is received, it is displayed on the display unit 151. As shown in FIG. 5B, upon receiving the preview file, the display unit 151 displays a reception confirmation message window 312 together with the preview file 311. The preview file may be a summary image generated by using a thumbnail image of a still image, a video clip file or a captured image of a moving image image, or additional information of an original file. Meanwhile, a yes icon 312-1 and a no icon 312-2 are further displayed on the reception confirmation message window 312. If the user selects the no icon 312-2, the original image file is rejected. If the user selects the yes icon 312-1, the transmission request signal for the original image file is transmitted.

Meanwhile, when receiving the preview image file, data indicating the type of the original image file may be received together. Then, the controller of the receiving terminal determines whether the original image file is a file that can be supported. In this case, if it is determined that it is not supported, as shown in FIG. 5C, the unsupported message 320 is displayed on the display unit 151.

This non-supportable message 320 includes a message asking for switching to a supportable file. When the user selects the yes icon 331 here, the file transmitted from the receiving terminal is converted into a file that can be supported. Alternatively, a file conversion request signal is transmitted to convert the file into a file supported by the transmitting terminal. When the user selects the no icon 332, reception of the original file is rejected.

Then, when the original file is received, the original image reception notification window 330 indicating the reception degree is displayed on the display unit 151 (see FIG. 5D). The reception notification window 330 may include a transmission progressive bar 331 indicating a transmission degree of the original image, and the expected end time 331-1 may be displayed on the progressive bar.

In the present embodiment, an example of transmitting an image file while executing an instant message service has been described. However, the present invention may also be applied to data transmission in a video call and data transmission in a voice call.
