[0021] It should be noted that in the following description, only the parts necessary for understanding the embodiments of the present invention will be described, and the description of other parts will be omitted to the extent that it does not deviate from the gist of the present invention.

[0022] The terms and words used in the following specification and claims should not be interpreted as being limited to their ordinary or dictionary meanings, but should be interpreted as meanings and concepts that correspond to the technical ideas of the present invention based on the principle that the inventor can appropriately define the concepts of terms to best describe his / her invention. Therefore, the embodiments described in this specification and the configurations shown in the drawings are merely preferred embodiments of the present invention and do not fully describe the technical ideas of the present invention, so it should be understood that there may be various equivalents and modifications that can replace them at the time of filing this application.

[0023] Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings. First, a system for downloading large amounts of data according to an embodiment of the present invention will be described. Fig. 1 is a diagram for explaining a system for downloading large amounts of data according to an embodiment of the present invention. Fig. 2 is a diagram for explaining a configuration of a terminal device for downloading large amounts of data according to an embodiment of the present invention.

[0024] Referring to FIG. 1, a system for downloading large amounts of data according to an embodiment of the present invention includes a server device 100 and a terminal device 200.

[0025] The server device 100 is basically an entity existing on a network, which stores data having information required by the terminal device 200 and provides the corresponding data in response to a request from the terminal device 200.

[0026] The terminal device 200 is basically a device used by a user. Representative examples of the terminal device 200 include a personal computer and a notebook computer. The terminal device 200 can connect to the server device 100 via a network and download data corresponding to user input.

[0027] According to an embodiment of the present invention, when the terminal device 200 receives a download request through the browser, the terminal device 200 transmits the download request to an agent, generates a new thread through the agent, and performs downloading from the generated thread in a socket manner, thereby allowing the user to use the browser for other tasks.

[0028] Meanwhile, referring to FIG. 2, the terminal device 200 includes a terminal communication module 210 , a browser module 220 , a download agent 230 and an export module 240 .

[0029] The browser module 220 is a module for controlling the browser handle, the browser interface, and the browser process. The browser module 220 can receive a request to download data by a user input (e.g., a link selection for download data). Then, the browser module 220 determines whether the download request matches a predetermined event condition.

[0030] According to one embodiment, the event condition may be that the amount of data corresponding to the download request is equal to or greater than a predetermined amount, i.e., the browser module 220 acquires the amount of data corresponding to the download request, and if the acquired amount of data is equal to or greater than a predetermined amount, it may determine that the condition is met.

[0031] According to another embodiment, the event condition may be that the download speed at the time of the download request is less than a predetermined speed. The browser module 220 may estimate the download speed and determine that the condition is met if the estimated download speed is less than the predetermined speed.

[0032] According to another embodiment, the event condition may be a case where the download time required based on the data volume according to the download request and the download speed at the time of the download request is equal to or longer than a predetermined time. The browser module 220 derives the volume and download speed of the data to be downloaded, estimates the download time required from the derived data volume and download speed, and determines that the condition is met if the estimated download time is equal to or longer than a predetermined time.

[0033] If the download request does not match a predefined event condition, the browser module 220 downloads the corresponding data. The browser module 220 performs downloading in an HTTP manner. On the other hand, if the download request matches a predefined event condition, the browser module 220 transmits a download request to the download agent 230. In this case, the browser module 220 can transmit the download request to the download agent 230 by providing download information corresponding to the download request to the download agent 230. Here, the download information includes a link, a data name, a file format for export, etc.

[0034] The download agent 230 is for performing downloading in a socket manner. Each time a download request is transmitted from the browser module 220, a thread corresponding to the download request is allocated. Also, the download process is performed in a socket manner through the allocated thread. In this way, the download agent 230 can simultaneously download multiple data as shown in FIG. 5 by allocating a thread each time a download request is transmitted and performing a download process in a socket manner through the allocated thread.

[0035] The export module 250 processes the downloaded data into a predetermined file format and exports it. The file format can be selected from a variety of formats, such as HTML, JSON, CSV, Excel, Hangul, MS-word, and PPT.

[0036] Next, a method for downloading large amounts of data according to an embodiment of the present invention will be described. Figure 3 is a flow chart for explaining a method for downloading large amounts of data according to an embodiment of the present invention. Figures 4 and 5 are examples of screens for explaining a method for downloading large amounts of data according to an embodiment of the present invention.

[0037] 3, the browser module 220 may receive a download request for data through a user input in step S110. When receiving such input, the user may select a file format for exporting the downloaded data, as shown in FIG.

[0038] Accordingly, in step S120, the browser module 220 determines whether the previously received download request (S110) satisfies a predetermined event condition.

[0039] According to one embodiment, the event condition may be that the amount of data corresponding to the download request is equal to or greater than a predetermined amount. That is, the browser module 220 adds the attribute “Range:bytes=0-1” to the HTTP header, and then acquires the amount of data corresponding to the download request using the HTTP GET method. If the acquired amount of data is equal to or greater than a predetermined amount, the event condition may be met.

[0040] According to another embodiment, the event condition may be a case where the download speed at the time of the download request is less than a predetermined speed. The browser module 220 may estimate the download speed by transmitting a beacon signal to a test server (not shown) for testing and receiving a response signal from the server. That is, the download speed may be estimated based on the round trip time (RTT) of the beacon signal and the response signal. Thus, the browser module 220 may determine that the condition is met if the estimated download speed is less than the predetermined speed.

[0041] According to another embodiment, the event condition may be a case where the amount of data requested for download and the download time required based on the download speed at the time of the download request are equal to or longer than a predetermined time. The browser module 220 may derive the amount of data to be downloaded and the download speed in the above-described manner, and then estimate the download time required from the derived amount of data and download speed. In addition, the browser module 220 may determine that the condition is met if the estimated download time is equal to or longer than a predetermined time.

[0042] If it is determined in step S120 that the download request does not match the predetermined event condition, the browser module 220 downloads the corresponding data in step S160. In step S160, the browser module 220 downloads the data in the HTTP format.

[0043] Meanwhile, if it is determined in step S120 that the download request meets a predetermined event condition, the browser module 220 transmits the download request to the download agent 230 in step S130. In this case, the browser module 220 can transmit the download request to the download agent 230 by providing download information corresponding to the download request to the download agent 230.

[0044] The download agent 230 that has received the download request can download the data according to the download information.

[0045] To this end, the download agent 230 allocates a thread whenever a download request is received in step S140, and then performs a download process in a socket manner through the allocated thread in step S150.

[0046] In this manner, the download agent 230 can simultaneously download multiple pieces of data as shown in FIG. 5 by allocating a thread each time a download request is transmitted and performing a download process in a socket manner through the allocated thread (51).

[0047] When the download is complete, the export module 250 processes the data in accordance with a predetermined file format previously (S110) and exports the downloaded data (Export) in step S170. For example, as shown in Fig. 5, the export module 250 can process the data into an Excel file and export it (53).

[0048] The method according to the embodiment of the present invention described above may be realized in the form of a program readable by various computer means and recorded on a computer-readable recording medium. Here, the recording medium may include program instructions, data files, data structures, and the like, alone or in combination. The program instructions recorded on the recording medium may be specially designed and configured for the present invention, or may be known and available to those skilled in the art of computer software. For example, the recording medium may include magnetic media such as hard disks, floppy disks, and magnetic tapes, optical media such as CD-ROMs and DVDs, magneto-optical media such as floptical disks, and hardware devices specially configured to store and execute program instructions, such as ROMs, RAMs, flash memories, and the like. Examples of program instructions may include not only machine language codes such as those produced by a compiler, but also high-level language codes that can be executed by a computer using an interpreter, etc. Such hardware devices may be configured to operate as one or more software modules to perform the operations of the present invention, or vice versa.

[0049] Although the present invention has been described above using several preferred embodiments, these embodiments are illustrative and not limiting. As such, it is understood that those skilled in the art can make various changes and modifications according to the doctrine of equivalents without departing from the spirit of the present invention and the scope of rights presented in the appended claims.
