The present invention relates to a method of transferring, converting and displaying a document file.

Conventionally, a document file is transmitted by mail using a document creation program (for example, Korean, Microsoft Word, etc.) or by mail using a document creation tool linked to the mail program.

However, the conventional document file transmission method is only possible through a wired network and does not disclose a method of viewing a document file by transmitting to a mobile communication terminal through a wireless network.

For example, if a mobile user loses documents and wants to explain the project to the customer urgently, he or she can bring the documents directly from the office, use the quick service to receive the documents, or receive the documents by fax nearby. There were ways to receive documents by e-mail and print documents from nearby PCs. In other words, recently, the spread of mobile communication terminals has been spread to about one per adult population, and the performance has been greatly improved. However, it has not been possible to receive documents using mobile communication terminals.

However, as the functions of the mobile communication terminals become more advanced, there has been a demand to utilize the mobile communication terminals for the purpose of receiving, storing, carrying and recycling various documents as well as entertainment.

Therefore, the present invention compresses and converts the file size so that the document file created on the PC can be transmitted to the mobile communication terminal through the mobile communication network, converts the web site set by the user into the document file, and uses the SMS technique to communicate with the other party. Send the file to the terminal and apply the security method to the contents so that important files can only be seen from the received terminal, print the file stored in the mobile communication terminal, and connect the external video device to save the file. It is an object to provide a comprehensive document file transfer, conversion, and display method for viewing.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described.

As shown in FIG. 1, the document file transmission system according to the present invention includes a PC A10, a server A50, and a mobile communication terminal A70.

The PC A10 creates a predetermined document file for transmitting the created document to the counterpart terminal A70 via the server A50. The PC A10 uses a document creation tool linked with a file transfer program or a previously created document file. You can select and send.

In order to transmit the document file created by the user, the user can select the created document file and input the telephone number of the counterpart terminal A70.

The server A50 drives the SMS transmission module to the phone number of the counterpart terminal A70 through the file transfer program through the wireless Internet to the document files delivered from a plurality of PCs, in addition to the PC A10, to the counterpart terminal A70. Sends a callback SMS to get consent to download the document file.

The other terminal A70 downloads the document file through the channel with the server A50 when the callback SMS transmitted from the server A50 is agreed by the user, and stores the document file in the storage unit of the mobile communication terminal A70.

A plurality of document files stored in the storage unit can be checked using a document file viewing software module of the terminal A70 or an external image device (for example, a TV) through an external image device connection terminal installed in the terminal A70. , LCD monitor, beam projector, etc.) to check the contents of the document file.

A document file transmission method according to the present invention will be described with reference to FIGS. 2 and 3. 2 is a flowchart of a method for transmitting a document created in a PC to a mobile communication terminal according to the present invention. As shown in Fig. 2, the user creates a predetermined document using a document creation tool (e.g., Hangul, MS Word, etc.) (S10), and the created document file is the telephone number of the counterpart terminal A70. Enter and transmit (S20). The transmitted document file information and the telephone number information of the counterpart terminal are transmitted to the server A50.

The server A50 receiving the transmitted document file drives the SMS transmission module based on the phone number of the counterpart terminal A70 transmitted together with the document file to inquire the counterpart terminal A70 whether to download the document file. Send a callback SMS (S30).

The callback SMS includes a message for inquiring whether the other party downloads the document file, the file name of the document file, and the name of the creator of the document file. This allows the other party to check the contents of the SMS and to know that there is a document file delivered to him.

Next, when confirming the SMS and approving the document file transmission in order to download the document file sent to him (that is, "Y1" in step S40), the document file is downloaded from the server A50 (S50), The user PC A10 transmits an approval result message indicating that the other party has approved (S60).

The document file downloaded to the counterpart terminal A70 can be checked as shown in FIG. 8 by using its own document file viewer. That is, as shown in FIG. 8, the transmitted document file can be confirmed through the display screen of the terminal A70 as if it were viewed using the document creation tool. In Fig. 8, for example, document contents written in Microsoft Word are displayed. Of course, such a document file can be enlarged (F20) and reduced (F10) using the viewer, full screen view (F60), screen rotation (F70) is also possible. In addition, it is possible to search for a character string to find in the document (F80, F90), and to view only the text portion except the image portion to fit the screen width (F40) to grasp the contents urgently. Even without a separate font in the mobile terminal, the document can be viewed in the same manner as the original (for example, Japanese, Chinese, English, etc.) regardless of the original language (F100, F110).

Of course, the terminal A70 may be connected to an external video device to check the contents of the document file on a large screen.

On the other hand, if the other party does not approve the transmission of the document file (i.e., "N" in step S40), the approval rejection result message is transmitted to the user PC A10 (S70).

In the above description, a method of transmitting a file from a PC to a counterpart terminal has been described. However, instead of a PC, a file may be transmitted by entering a counterpart terminal number and a file by accessing a web site capable of file transfer.

3 illustrates a method of accessing a portal site and sending a document. When there is no separate conversion software in the PC, when the portal site is connected and the document is sent, the portal site server A30 converts the document and transmits the document to the terminal A70. At this time, the conversion software must be installed in the portal site server A30.

Next, FIG. 4 is a flowchart of transferring a file from the PC A80 to the terminal A70 via a USB cable or Bluetooth. Run the file download software installed in the PC (A80), select the file to download to the terminal (A70) in the window to download and convert the file according to the algorithm shown in Figure 6 sent to the terminal (A70) Lose. That is, when converting a file, text and image are first distinguished (T20). After the classification, the text converts the Unicode-compatible font into a vector image, and the general image integrates similar images while reducing the file size by optimizing the loss ratio (T30). This verifies that the total size of the reduced files after conversion is greater than 250 KB. If the size exceeds 250KB, the file is divided in 250KB units, and the file name is ordered. This completes the conversion to a file size that can be transferred from the mobile network.

5 is a flowchart illustrating a method for displaying a file viewed by a terminal to an external video device. It is determined whether the file displayed on the terminal is written in the horizontal direction or in the vertical direction (D10), and allocates an area of memory to be displayed in accordance with the direction and sends it to the graphics memory (D40, D100). When displaying a file with an external video device, the enlargement ratio must be over 150%.

Through the present invention, not only general documents but also various types of files such as materials, drawings, magazines, books, music scores, and bills may be transmitted.

In addition, a description of the method of viewing the contents of the website set by the user as a variation of the document file transmission method of the present invention on the user's portable terminal, first set up the website that the user wants to download from the PC Request to download from communication terminal. Then, the contents of the set website are converted into a document file on the PC and transmitted to the mobile communication terminal for download and viewing through Bluetooth or USB.

When a user sets up on a web server instead of a PC and requests a download from a mobile communication terminal, it converts the contents of the web site into a document file and sends it down to the mobile communication terminal on the network to view the document file on the terminal.

As described above, according to the present invention, since the documents created on the PC can be transmitted to the other party's mobile communication terminal through the mobile communication network regardless of the type of the language in which the original file is written, anytime, anywhere, Any type of document files can be transmitted, so the mobile communication terminal can be used as a ubiquitous terminal.
