The input unit 110 is an input device for receiving selection of data to be transmitted to the counterpart from the user. The user may select one of the data already stored in the first mobile communication terminal 100 through the input unit 110, or input new data into the first mobile communication terminal 100 through the input unit 110. have.

The file encoding unit 120 generates a file of the electronic business card format including the data selected by the input unit 110 and a type identifier indicating the type of the selected data. Here, the type of data may include a phone book (phone book), an image, a sound, an electronic business card, and the like. Meanwhile, the electronic business card format is a format that can define various types of data (phonebook, image, sound, electronic business card, etc.), and may be in accordance with an electronic business card standard (vCard), but the present invention is not limited thereto. .

The controller 130 controls the electronic card format file generated by the file encoding unit 120 to be transmitted to the counterpart mobile communication terminal (second mobile communication terminal 200) through the infrared transmitter 140.

The infrared ray transmitter 140 transmits the file to the second mobile communication terminal 200 through infrared communication under the control of the controller 130. The infrared transmitter 140 may transmit a file according to an IRDAEX (IrOBEX: IrDA Object-Exchange Protocol), but the present invention is not limited thereto.

3 is a diagram illustrating a configuration of a mobile communication terminal according to another embodiment of the present invention. Referring to FIG. 3, a mobile communication terminal (hereinafter referred to as a second mobile communication terminal 200) according to another embodiment of the present invention may include an infrared receiver 210, a file decoder 220, a controller 230, and a memory unit. 240.

The infrared receiver 210 is a device for receiving a file from a counterpart mobile communication terminal (first mobile communication terminal 100).

While the first terminal 100 performs steps S110 to S130, the second terminal 200 drives an infrared receiver to switch to a reception mode (step S14O). 8 and 9 illustrate examples of screens that may be displayed on the second terminal 200 while the second terminal 200 switches to the reception mode. Here, since the reception mode is not divided by data type, the user of the second terminal 200 only needs to select 'switch to the reception mode', and among 'switch to the phonebook reception mode' and 'switch to the image reception mode', etc. There is no need to choose one.

4 and 5 again, the first terminal 100 transmits the file of the electronic business card format generated in step S130 through infrared communication and the second terminal 200 receives the transmitted file (step S150). ). An example of a screen that may be displayed on the first terminal 100 in the process of transmitting a file is shown in FIG. 10. The second terminal 200 extracts the type identifier from the file received in step S150 to obtain data type information (step S160). The second terminal 200 extracts data from the file received in step S150, and decodes the data according to the data type information obtained in step S160 (step S170). Then, the second terminal 200 stores the data decoded in step S170 in a folder matching the data type information obtained in step S160 (step S180). An example of a screen that may be displayed on the second terminal 200 after data storage is completed is shown in FIG. 11. After completing the storage of the data, the second terminal device 200 may transmit a reception completion message to the first terminal 100 (step S190).
