Referring to FIG. 1, the mobile communication terminal 100 includes a key input unit 110 for selecting a file to be transmitted to a counterpart and a size of a file selected by the key input unit 110 exceeds a reference value. After dividing the file into a certain size, the split information is included in the header of the split file and transmitted, and when the file is received through a short range wireless communication method, it is determined whether the received file is the split file. A control unit 120 that receives and generates a single file, and stores various terminal information of the mobile communication terminal, and stores a random program and a split program for dividing a size of a file exceeding a reference value ( 130, a display unit 140 that provides an external display window and / or an internal display window, a voice processing unit 150, a microphone 160, a speaker 170, and a ground. Is configured, including as a local area wireless communication unit 180 for performing radio signal processing with wireless communication, mobile communication terminals such as the cellular communication section 190 that performs signal processing for wireless communication.

The control unit 120 controls the overall operation of the mobile communication terminal and selects a file to be transmitted to the other party, and when the size of the selected file exceeds a reference value, the controller 120 selects a predetermined file through a divided program stored in the memory 190. And the split information is included in the header of the split file and transmitted through the short range wireless communication unit 180. At this time, the terminal of the other party is provided with a short range wireless communication module for performing short range wireless communication, and performs communication through a short range wireless communication method.

In addition, when receiving a file through a short-range wireless communication method, the controller 120 analyzes the header of the received file and determines that the file is a split file. When the split file is received based on the split information of the split file, the controller 120 receives the split file. Create a file using the files. Here, the split information refers to a type of a file to be transmitted, a number of files to be transmitted, an index of a split file to be transmitted currently, a number of split files, and the like.

In addition, when an error exists in the received split file, the controller 120 stores the index of the split file included in the header of the split file in the error index library. Accordingly, the controller 120 determines whether the error index list exists in the error index storage box, and if the error index list exists, transmits the error index list to re-receive the corresponding split files to correspond to the re-received split file. Insert the index to finish creating the file.

Here, the index of the partition is an order value of the currently transmitted split file among all the split files when the file is divided and transferred, the split file is file data divided into a predetermined size among the entire files for split transfer, and the error index list is Refers to a list of split file indexes where an error occurs due to various causes during transmission and reception.

The short range wireless communication unit 180 converts a signal output from the control unit 120 into a short range wireless communication type radio signal to communicate with a terminal of a counterpart in a short range wireless communication section. In addition, the short range wireless communication unit 180 converts the short range wireless communication type wireless signal received from the terminal of the other party in the short range wireless communication section into a desired signal and outputs the converted signal.

Here, the short range wireless communication unit 180 is described as performing communication in an IrDA communication method, but is not limited thereto and may perform communication in an RF communication method and an ultra-wide band (UWB) communication method.

The cellular communication unit 190 is controlled by the controller 120 and converts a signal output from the controller 120 into a wireless signal. In addition, the cellular communication unit 190 converts the radio signal received through the antenna ANT into a desired signal and outputs it.

The voice processing unit 150 modulates the voice signal input from the microphone 170 and converts the voice signal into voice data, and converts the voice data input from the cellular communication unit 190 and voice data stored in the memory 130 into voice signals. The demodulator outputs the voice through the speaker 160.

The key input unit 110 includes a plurality of numeric keys, a menu key, and a function key for performing various functions, and outputs key data to the controller 120 by an external operation. In this case, the key input unit 110 selects a directory in which a file to be transmitted to the counterpart is stored, and selects a corresponding file from the selected directory.

Accordingly, the controller 120 reads the menu from the memory 130 according to the user's menu display request by the key input unit 110 and displays the menu on the display unit 140. That is, the key input unit 110 is a conventional user information input means, and has a plurality of keys suitable for a mobile communication terminal to be applied, such as a plurality of numeric keys and function keys, and if there is an input of each of the provided keys, Therefore, by outputting the corresponding unique key data to the control unit 120, through the key input operation of the key input unit 110 is entered into the menu display mode and selection of the menu is made. Then, the controller 120 reads the menu according to the corresponding key input from the memory 130 and displays the menu on the display unit 140.

The display unit 140 is a display device such as a liquid crystal display (LCD). The display unit 140 displays the state of the mobile communication terminal or the progress of the program under the control of the control unit 120. That is, the overall state of the mobile communication terminal and input user information are displayed.

In the memory 130, an operation program and a system program of the controller 120 are stored, and the operation program or system program is stored in a ROM region which is normally included and can be erased as necessary. Electrically erasable ROMs include EEPROM and flash memory. The memory 130 also includes a RAM that temporarily stores data generated during execution of various operating programs.

In addition, the memory 130 stores a segmentation program for dividing an arbitrary file (for example, an image file, a music file, a video file, a text file, etc.) and a file size exceeding a preset reference value. .

Referring to FIG. 2, the controller 120 may include a mobile communication processor 120a, a file selector 120b, a comparison determiner 120c, and a division processor, which perform signal processing for performing a mobile communication service. 120d), the transmission processing unit 120e, the retransmission processing unit 120f, the reception processing unit 120g, the header analyzing unit 120h, the error determining unit 120i, the storage processing unit 120j, and the file generation Section 120k, error file processing section 120l, and the like.

The mobile communication processing unit 120a is a module for performing a mobile communication service using a radio resource in a mobile communication terminal, and is configured and operated using a known mobile communication technology.

The file selection unit 120b selects a preset transmission menu item for transmitting a file to the counterpart using a short range wireless communication method (for example, IrDA communication method), and transmits a file from a directory provided through the selected menu item. Select

The comparison determination unit 120c compares the size of the file selected by the file selection unit 120b with a reference value (for example, 2,048 KB) to determine whether the reference value is exceeded. At this time, if the size of the selected file does not exceed the reference value, the selected file is transmitted.

The division processing unit 120d divides the file into a predetermined size (for example, 2,048 KB) when the size of the file selected by the file selection unit 120b exceeds the reference value as a result of the determination by the comparison determination unit 120c. It plays a role. Here, the predetermined size is the size of the file having the optimal error rate.

In addition, the division processing unit 120d includes the division information in the file divided into a predetermined size. In this case, the split information included in the divided split file is a type of a file to be transmitted, a number of files to be transmitted, an index of a split file to be transmitted currently, a number of split files, and the like.

The transmission processing unit 120e transmits the divided file divided by the division processing unit 120d to the terminal of the other party through the short range wireless communication unit 180. In this case, the file not exceeding the reference value, which is not subjected to the division process by the division processing unit 120d, is also transmitted to the terminal of the other party through the short range wireless communication unit 180.

In addition, when all of the divided files are transmitted, the transmission processing unit 120e transmits the file transmission completion signal and then completes the transmission procedure. Similarly, a file transmission completion signal is also transmitted in the case of a file which is not a divided file and does not exceed a reference value.

When the retransmission processing unit 120f receives the error index list from the terminal of the other party, the retransmission processing unit 120f retransmits the split file corresponding to the received error index list. In this case, the error index list refers to the index of the current split file to be transmitted.

The reception processing unit 120g performs a function of receiving a file through a short range wireless communication method.

The header analyzer 120h analyzes the header of the file received by the reception processor 120g to determine whether the header file is a split file.

The error determining unit 120i determines whether an error exists in the received split file when the header analyzing unit 120h identifies the split file.

If there is no error in the split file received by the error determining unit 120i, the storage processor 120j stores the received split file in the split index library, and stores the error in the split file received by the error determining unit 120i. If exists, stores the index of the received split file in the error index library.

The file generator 120k generates one file by using the normal split file stored in the partition index library. In other words, one file is created by using split file operations stored in the partition index library. In this case, the generated file is stored and managed in the memory 130.

The error file processor 120l determines whether the index of the split file exists in the error index library, and if the index of the split file exists in the error index library, requests the retransmission of the error index list to re-receive the corresponding split file. . At this time, if an error does not exist in the re-received split file, it is stored in the above-mentioned partition index library. If an error exists in the re-received split file, the error index list is retransmitted again to re-receive the corresponding split file.

In addition, when an error exists in the received file, the error file processing unit 120l re-receives split files corresponding to the corresponding error index list for which retransmission is requested, and inserts the re-received split file into the corresponding index position. If there are no more errors in the split file, one file is finally created.

In this way, a file exceeding a reference value is divided into a predetermined size, and file information is included and transmitted in the divided file to reduce a reception failure rate during transmission and reception.

A method of transmitting and receiving a file in a mobile communication terminal according to an embodiment of the present invention configured as described above will be described.

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

Referring to FIG. 3, the control unit 120 of the mobile communication terminal 100 previously stores, in the memory 130, a division program for dividing an arbitrary file and a file exceeding a preset reference value into a predetermined size (S101). ).

The file selector 120b of the controller 120 selects a file to be transmitted to the counterpart (S103). At this time, the method of selecting a file selects a preset transfer menu item and selects a corresponding file from a directory provided through the selected menu item.

The comparison determination unit 120c of the control unit 120 determines whether the size of the selected file exceeds a reference value (S105).

As a result of the determination in step S105, when the size of the selected file does not exceed the reference value, the transmission processor 120e of the controller 120 causes the selected file to be transmitted to the terminal of the counterpart through the short range wireless communication unit 180 (S106). ). Thereafter, the process moves to step S111.

As a result of the determination in step S105, when the size of the selected file exceeds the reference value, the division processing unit 120d of the control unit 120 divides the file into a predetermined size (for example, 2,048 KB), and the header of the divided file. Include the split information in (S107).

Here, the split information included in the header of the file is as shown in FIG.

Referring to FIG. 6, Item_Type is a type of a file to be transmitted (such as a phone book, a schedule, a picture, a message, a V card, etc.), Num_Of_Item is the number of data when there are several data to be transmitted, and Part_Num_Of_File is divided into 2,048KB. The index of the split file to be transferred among files, and Total_Num_Of_File is the number of split parts when the data to be transmitted is divided into 2,048 KB.

For example, if one picture file having a size of 4000KB is transmitted, the file is divided into 2,048KB, which is a certain size, and the split information is included in the headers of the two split files. The header of the first split file is 2,1, 1,2, 'L', 'G', 'M', 'o', 'b', 'i', 'l', 'e', and the header of the second split file is 2,1,2, 2, 'L', 'G', 'M', 'o', 'b', 'i', 'l', 'e'.

Next, the transmission processor 120e of the controller 120 transmits the split file including the split information in the header of the split file to the terminal of the counterpart through the short range wireless communication unit 180 (S109).

Next, when the transmission of the corresponding file is completed, the transmission processor 120e transmits a transmission completion signal (S111).

After that, the retransmission processing unit 120f of the control unit 120 determines whether an error index list has been received (S113).

As a result of the determination in step S113, if no error index list is received, the process ends.

As a result of the determination in step S113, when the error index list is received, the retransmission processor 120f retransmits the split file corresponding to the error index list to the corresponding receiver through the short range wireless communication unit 180 (S115).

By doing this, even if the file is large, it is possible to reduce the reception failure rate by dividing the transmission to a certain size.

4 is a flowchart illustrating a file transmission / reception method in a reception mode in a mobile communication terminal according to an embodiment of the present invention.

Referring to FIG. 4, the reception processor 120g of the controller 120 receives a file through a short range wireless communication method (S201).

Next, the header analyzer 120h of the controller 120 analyzes the header of the received file to determine whether the file is a split file (S203).

As a result of the determination in step S203, if it is not a divided file, the reception processing unit 120g receives a transmission completion signal transmitted from the transmission side (S204).

Next, the storage processor 120j of the controller 120 stores the received file in the memory 130 (S206).

As a result of the determination in step S203, in the case of a split file, the error determiner 120i of the controller 120 determines whether an error exists in the received split file (S205).

As a result of the determination in step S205, if an error exists in the received split file, the storage processor 120j stores the index of the split file in the error index storage box (S208).

As a result of the determination in step S205, when no error exists in the received split file, the storage processor 120j stores the split file in the split index library (S207).

Next, the reception processing unit 120g receives a transmission completion signal (S209). At this time, the transfer completion signal is a signal indicating that the transfer of the divided file (for example, the normal divided file or the error divided file) or the undivided file is completed. Accordingly, it can be seen that there is no split file to receive when there is no error split file.

Thereafter, the error file processing unit 120l of the controller 120 determines whether an error index list exists in the error index storage box (S211). Here, the error index list refers to the index list of the split file where the error occurs.

As a result of the determination in step S211, when the error index list does not exist in the error index storage box, the error file processing unit 120l transmits a reception completion signal to the transmitting side (S213).

As a result of the determination in step S211, if the error index list exists in the error index storage box, the error file processing unit 120l transmits the error index list to the transmitting side (S212). Thereafter, the process moves to step S201 to receive the corresponding split file in the error index list through the short range wireless communication unit 180.

Next, the file generator 120k of the controller 120 generates one file using the split file stored in the partition index library (S215). At this time, the error index list is transmitted to re-receive the corresponding files, and the re-received file is inserted into the corresponding index position to generate a file. The file generated as described above is stored and managed in the memory 130.

By doing this, when an error exists in the divided file received by dividing to a certain size, only the divided file in which the error exists can be re-received to increase the reception efficiency.

The present invention is not limited to the embodiments described above, and various modifications and changes can be made by those skilled in the art, which are included in the spirit and scope of the present invention as defined in the appended claims.

According to the present invention as described above it is possible to reduce the error occurrence rate and reception failure rate during transmission and reception by transmitting the file information included in the divided file by dividing the file exceeding the reference value to a certain size.

In addition, according to the present invention as described above, when there is an error in the divided file received by dividing to a certain size, there is also an effect of re-receiving only the split file in which the error exists to greatly increase the transmission and reception efficiency.
