Communication speed adaptive file transfer system

The present invention relates to a communication speed adaptive file transfer system.

In more detail, when the information generated between the information provider and the client moves in a general-purpose communication network such as the Internet, a normal mode for normal information transmission and information controlled automatically according to the communication speed Communication speed adaptive file transfer system that enables users to transfer the desired information more quickly and efficiently through various modes such as communication speed adaptation mode for user and user selection mode for information transmission according to the selected communication speed. will be.

In general, information providers convert and store various types of information in the form of text or images, and store the information through communication networks such as the Internet, a local area network (LAN), and a wide area network (WAN). According to the user's request to use the text file or image file is transmitted.

That is, when the user selects the information in the form of a conversation after connecting with the information provider through the communication network, the information provider provides the user with a file containing the corresponding information selected by the user.

1 is a view for explaining a communication network connection type between a general information provider and a user as described above.

As shown, the information provider 10 converts and stores various types of information into a text / image file, and stores and stores the information connected to the general-purpose communication network 20 to be described later. To be available).

The general purpose communication network 20 is a LAN, WAN, Internet, general communication service provider network, etc. which allow a plurality of information providers 10 and a user terminal 30 to be described later to connect and exchange information with each other.

The user terminal 30 may select and view various types of information from the information provider 10 having desired information after connecting with the general purpose communication network 20, and if desired, view the corresponding information through the general purpose communication network 20 in the form of a file. Received by

As described above, information transmission between the information provider 10 and the user terminal 30 through the universal communication network 20 is performed as follows.

Characterized in that configured as a user terminal receiving.

Hereinafter, with reference to the accompanying drawings will be described in detail the transmission rate adaptive file transfer system of the present invention.

Here, the communication speed adaptive file transfer system of the present invention is used in all the communication networks of FIG. 1 describing the communication network connection form of the information provider and the user, and the configuration of FIG. 1 is applied as it is.

The information provider 10 stores a plurality of converted files having different sizes according to the communication speed in response to the original file or the original file selected by the user, and the original file or the plurality of converted files according to the user's file or file transfer mode selection. Any one of the files is transmitted to the user terminal 30 to be described later.

The information provider 10 and the user terminal 30 described later are provided with a communication speed detecting means (not shown) for detecting the current communication speed, the user terminal 30 detects the current communication speed. In the case of transmitting the information to the information provider 10, the information provider 10 applies the current communication speed transmitted from the user terminal 30 in preference to the current communication speed detected within the user.

The above-described file transfer mode includes a normal mode for transmitting the original file regardless of the current communication speed, a communication speed adaptation mode for transmitting a file having a size corresponding to the communication speed detected by the communication speed sensing means described below; It consists of three modes: user selection mode, which transmits a file of a size corresponding to the communication speed selected by the user among the original file and the plurality of converted files.

In addition, the information provider 10 transmits a file of a corresponding size corresponding to the detected current communication speed to the user terminal 30 to be described later when the communication speed adaptation mode is selected among the file transfer modes by the user.

The user terminal 30 selects a file or a file transfer mode by the user, and receives a file transmitted from the information provider 20 through the universal communication network 20 according to the file or file transfer mode selection.

The user terminal 30 is also equipped with display means (not shown) for informing the user of the detected current communication speed and the selectable file or file transfer mode.

FIG. 2 is a flowchart illustrating an operation of file transfer according to a communication speed of the present invention in detail. A first process in which a user connects to the information provider 10 through the universal communication network 20 through the user terminal 30 (S100). And a second step (S200) in which the user selects a file transfer to receive a file from the information provider 10, and if the file transfer is selected by the user, a file in a normal mode, a communication speed adaptation mode, and a user selection mode. A third step (S300) of displaying the transfer mode on the screen (S310) and determining which file transfer mode is selected by the user among the displayed file transfer modes (S320), and the third process (S300) described above. Through one of the normal mode (S410), the communication speed adaptation mode (S420), the user selection mode (S430) according to the file transfer mode selected by the user to transfer any one of the original file and a plurality of converted files through The fourth process consists of (S400).

The normal mode (S410) of the file transfer mode of the fourth process (S400) described above comprises the step (S411) of selecting the original file regardless of the current communication speed among a plurality of files stored in the information provider 10, The selected original file is transmitted to the user terminal 30 (S412).

In the file transfer mode of the fourth step (S400), the communication speed adaptation mode (S420) detects a current communication speed of the user terminal 30 when a file transfer is selected by the user (S421) and detects the user. Transmitting the current communication speed and communication speed selection menu (S422), determining whether the current communication speed detected through the above-described step S422 is selected by the user (S423), and If the current communication speed detected as a result of the determination in step S423 is selected by the user, selecting a file having a size corresponding to the selected current communication speed from among a plurality of files stored in advance (S424), and the above-described step If the current communication speed detected as a result of the determination in S423 is not selected by the user, it corresponds to the communication speed selected by the user according to the communication speed selection menu among a plurality of stored files. Selecting a file having a size (S425), and the step (S426) and the step (S426) for transmitting the selected file to the user terminal 30 through the step (S425).

In addition, the user selection mode (S430) of the file transfer mode of the fourth step (S400) is a user indexes corresponding to files of different sizes used for the transmission stored by the information provider 10 when the user selects a file transfer A step S431 of transmitting to the terminal 30, a step S432 of arbitrarily selecting by the user according to the index transmitted to the user terminal 30 through the step S431, and the step S432 described above. In step S433, the user selects a file corresponding to the index selected by the user, and transmits the selected file to the user terminal 30 (S434).

Next, the operation of the communication speed adaptive file transfer system according to the present invention configured as described above will be described in detail.

First, unlike the conventional method, the information provider 10 stores not only the original file but also a plurality of converted files smaller in size than the original file, and the original file stored according to the user's file transfer request. Any one of a plurality of converted files is selected and transmitted to the user terminal 30.

For example, when the information provider 10 converts and stores any one color image into a file, the information provider 10 uses the original file that preserves the color image as it is, and the color to make the size smaller than the original file. You will save several files of different sizes, such as ones that are reduced or saved in gray.

Therefore, when the communication speed is slow or when the file needs to be checked within a short time, users can greatly reduce the time when the small size of the file stored by the information provider 10 is transmitted. If you try to play after receiving a smaller file, the original color cannot be reproduced.

In addition, the information provider 10 names each file in a predetermined order to distinguish files having different sizes of the same contents.

For example, if the name of the file is ABC_PN_SN.EXT, ABC is the name set by the information provider 10 to distinguish multiple files, PN is the page number, SN is the baud rate number, and EXT is img, gif. file extension, for example, txt. At this time, the communication speed classification number is a number assigned to each communication speed when the information provider 10 stores the file divided into communication speeds according to two or more steps such as normal speed, high speed, and ultra-high speed (and, in the user selection mode described later) Index provided to the user). Therefore, if a user wants to receive 10 pages of ABC image files at high speed (for example, assumes a normal speed of 1, a high speed of 2, and an ultra high speed of 3), the information provider 10 reads ABC_10_2.IMG among several stored files. The file is selected and transmitted to the user terminal 30. The file name setting by the information provider 10 as described above may be performed in a manner other than the above-described manner.

Now, after a plurality of users are connected to the information provider 10 through the communication network (20) (S100), when requesting the provision of information, that is, file transfer, the user transmits the file displayed on the screen of the user terminal 30. The button is pressed (S200).

When the file transfer is selected by the user as described above, the information provider 10 requests the user to select a normal mode, a communication speed adaptation mode, or a user selection mode.

That is, a button for a normal mode, a communication speed adaptation mode, and a user selection mode is displayed on the screen (S310), and it is determined which file transfer mode is selected by the user among the displayed file transfer modes (S320).

As a result, when the user selects the normal mode (S410) at the time of file transfer, the information provider 10 selects the original file regardless of the current communication speed among several files stored (S411) and then selects the selected original file. It is transmitted to the user terminal 30 (S412).

When the user selects the communication speed adaptation mode (S420) at the time of file transmission, the user detects the current communication speed of the user terminal 30 (S421), and selects the current communication speed and communication speed selection menu detected by the user. The user terminal 30 transmits the data to the user terminal 30 (S422). At this time, when the information provider 10 detects the communication speed of the user terminal 30, it is calculated using a counter provided in the information provider 10. It is determined whether the current communication speed detected through the above-described step S422 is selected by the user (S423), and when the detected current communication speed is selected by the user, the current communication selected from a plurality of files stored in advance. A file of a size corresponding to the speed is selected (S424). However, if the current communication speed detected as a result of the determination in step S423 is not selected by the user, a file having a size corresponding to the communication speed selected by the user according to the communication speed selection menu among a plurality of stored files is stored. Select (S425). In this way, the selected file is transmitted to the user terminal 30 through the above-described steps S424 and S425 (S426).

In addition, when the user selects the user selection mode (S430) when transmitting a file, the information provider 10 is stored in files of different sizes stored by the information provider 10 according to the communication speed when selecting a file transfer by the user. The corresponding index is transmitted to the user terminal 30 (S431). When the user selects one index according to the index transmitted to the user terminal 30 through the above-described step S431 (S432), after selecting a file corresponding to the index selected by the user (S433), The file is transmitted to the user terminal 30 (S434).

Meanwhile, although not shown in FIG. 2, the user may change the file transfer mode by the user's selection while receiving the file from the information provider 10 according to the normal mode, the communication speed adaptation mode, the user selection mode, or the like. In this case, the current file transfer is performed according to the previously selected file transfer mode, but subsequent file transfers are performed according to the newly changed file transfer mode.

In addition, in the present invention, the file transfer mode is selected by the user to select the file transfer mode as an example, but the present invention is not limited thereto. In addition, when the user accesses the information provider through the user terminal, a plurality of previously stored files are displayed Of course, it can be configured to transmit the file selected by the user among the plurality of files displayed.

As described above, according to the communication speed adaptive file transfer system of the present invention, when each user connected to the information provider requests the provision of information or while the file transfer is being performed, the user can freely change the information transmission mode according to the communication speed. Because of the choice, it is possible to maximize the efficiency of the communication channel as well as quick information retrieval and information transmission.

In addition, even in the information provider, although the burden of increasing the storage capacity is increased, the efficiency of the communication channel is increased, which can be used by more users and has the advantage of providing information to users smoothly.
