The present invention relates to an update file providing apparatus, a method thereof, an update file downloading apparatus using the same, and a method thereof, and a computer-readable recording medium recording a program for realizing the method. The server provides an update file for each unit file by breaking the existing version (file group) update file providing method, and the update information downloaded from the update file providing server by the update file downloading terminal (for example, a personal computer). (Xm file) compared to the pre-installed files, if there is a difference unit file corresponding to the update file providing server to download the update file by requesting the corresponding file, when updating (file updating) resources (update Improve the efficiency of the use of time, network resources, etc.) Relates to an update file providing apparatus and method using the same, and update file downloading apparatus and method, and a computer-readable recording medium recording a program for realizing the method for Pointing.

Today, the update file (update file) is used in various ways for the purpose of improving the function of the existing program or to maintain security.

Here, an update file downloading process (existing file updating process) currently used generally will be described with reference to FIG. 1.

1 is a flowchart illustrating a method for transmitting / receiving an update file for each version (by file group) according to the prior art.

Currently, a server for providing an update file and a client (eg, a personal computer) attempting to update the file are connected through a wired / wireless communication network.

First, the client requests (101) the server to download an update file for any program.

The server then transmits (102) a text file for the update file currently registered for the program. At this time, version information is recorded in the text file.

Upon receiving the text file, the client compares (103) the version information of an existing program and the version information recorded in the text file with each other to update the version-specific update file (program execution file) to be installed. Downloads sequentially from the server (104). At this time, a plurality of update files are all downloaded, from the low update file to the latest update file.

Then, the client installs the downloaded version-specific update file in turn (depending on the version) (105). More specifically, the update file for each version is extracted and executed after copying to the storage space.

That is, the method of providing update files for each version according to the prior art has a problem in that all of them are sequentially downloaded from a low version update file to a high version update file. This is caused by transferring version information using a text file, which causes a lot of inconvenience and waste of resources such as time.

In addition, most version-specific update files are compressed files, which themselves include a number of files (ie, each update file is a kind of file group). However, when each update file is downloaded for each version as shown in FIG. 1, even though the versions of each update file are different, they often include the same file, so that some files are repeatedly downloaded. There is this.

For example, a 1.0 update file (which is a compressed file) contains a, b, and c files, and a newly released version 1.1 update file (which is a compressed file) is upgraded compared to a, b files (version 1.0). Files), if the two versions of files are downloaded sequentially, a and b files are downloaded in duplicate. That is, since the client first installs version 1.0 and then installs version 1.1, there is a problem of causing various resources (eg, unnecessary network traffic) due to double downloading.

In addition, in the prior art, the client is to install the update file for each version (for example, the update file of the 1.0 / 1.1 version) in order to perform this sequentially, so that you have to wait a long time until all procedures are completed There was a problem. That is, by sequentially decompressing and copying the update file for each version and executing the entire process sequentially, there is a problem in that the file installation time is lengthened.

The present invention has been proposed to solve the above problems, and there may be a difference by comparing the update information registered in the update file providing server (xm file) and the files already installed in the update file downloading terminal when updating the file. In this case, by downloading the corresponding unit file as an update file, an update file providing device and a method thereof and a method for using the same to avoid updating the file providing method according to the version comparison and to update the file more efficiently An object of the present invention is to provide an update file downloading apparatus and a method thereof, and a computer-readable recording medium recording a program for realizing the method.

That is, the present invention enables the update file downloading terminal to provide update information currently registered in the update file providing server by using an XX (eXtensible Markup Language), which is a standard language of data management and exchange. By downloading the corresponding unit file corresponding to the pre-installed file to be updated according to whether there is a difference between the file pre-installed in the downloading terminal and the update information (x-M-L file) as an update file, update by version An update file providing device and a method thereof, an update file downloading device using the same, and a method for realizing a method for updating a file more efficiently than a file providing method, and a computer recording a program for realizing the method. To provide a readable recording medium There is a purpose.

In addition, the present invention downloads and installs each unit file selected as an update target from an update file providing server in order, and uses various threads to process each unit file using a multithread, that is, a downloading process and By performing the decompression process and the copy process in parallel, an update file downloading apparatus and method for reducing the file installation time during file updating, and a computer for recording the program for realizing the method are read. The purpose is to provide a recording medium that can be used.

That is, according to the present invention, when an update file downloading terminal (eg, a personal computer) updates a file, each thread generates a thread for each processing process (eg, a downloading process and a decompression / copying process) to generate a plurality of unit files. It is an object of the present invention to provide an update file downloading apparatus and method for reducing file installation time and a computer-readable recording medium having recorded thereon a program for realizing the method by processing in parallel.

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

The present invention allows not to provide an update file for each version (that is, for each file group) but to download each file for each objectized unit file, but uses update information (file name, file) by using eXensible Markup Language. Size, last modified date, file contents, etc.), allowing you to selectively download each unit file that needs updating. In other words, by updating an object to be compressed, transmitted / received, and decompressed for each unit file, it is possible to reduce waste of various resources due to duplicate processing.

In addition, in the present invention, in the update file downloading terminal which downloads the update file for each unit file, the update file is processed in parallel by different threads for each detailed process (eg, downloading process, decompression and copying process). By doing so, the file installation time is reduced.

In the following embodiment, the case where the update file providing server 10 and the update file downloading terminal 20 transmits / receives various signals and files through the Internet will be described as an example.

First, referring to FIG. 2, the components of an update file providing server for providing an update file for each unit file are as follows.

2 is a diagram illustrating an embodiment of an update file providing server for each unit file according to the present invention.

As shown in FIG. 2, the update file providing server for each unit file according to the present invention includes an update request receiving unit 11 and update information for receiving an update request signal and a download request signal for each unit file from the outside. File transmission unit 12 for transmitting the update file generated for each unit file to the outside, and the file information generated by XML (stores the file name, file size, last modified date, encrypted file content, etc. for each unit file) File storage unit 13 for storing the update file objectized for each unit file, and the update request signal from the external update file downloading terminal 20 through the update request receiving unit 11. By transmitting the update information (an XL file) stored in the storage unit 13 to the update file downloading terminal 20 A controller 14 for selecting an existing installation file to be updated and transmitting the corresponding unit file to the update file downloading terminal 20 in response to receiving a download request signal for each unit file corresponding thereto. ).

At this time, the control unit 14 performs the overall control of the update file providing server 10, and at the same time, performs a function for providing an update file for each unit file according to the present invention. In other words, instead of providing the entire file group corresponding to each version for each version as an update file, update information generated by using XML is provided so that it can be selectively downloaded for each unit file. For example, if the prior art provided a, b, and c files as one file group in version 1.0 and a and b files as a new file group in version 1.1, the present invention provides a, b, and c files. Is provided as a unit file.

Looking at each operation of the controller 14 in more detail, the current file storage unit 13 includes a file name, file size (size), last modified date, file contents (encrypted), etc. for each unit file. It stores the update information (XM file) and the update file for each unit file. The uploading of the update file for each unit file will be described later.

The control unit 14 receives the update request signal from the external update file downloading terminal 20 through the update request receiving unit 11, and transmits the update information stored in the file storage unit 13 to the file transmitting unit 12. ) To the update file downloading terminal 20. That is, the update file downloading terminal 20 may compare the existing installation file and the update information and select an existing installation file to be updated.

Subsequently, the control unit 14 receives a download request signal for each unit file through the update request receiving unit 11, and searches for a corresponding unit file (compressed file) from the file storage unit 13 to obtain a file. The transmission file 12 is transmitted to the update file downloading terminal 20. That is, by allowing the corresponding unit file selectively requested by the update file downloading terminal 20 to be downloaded, an existing installation file (an existing installation file selected as an update target) can be updated.

Meanwhile, the file storage unit 13 stores various system programs, application programs, file systems, and the like. In addition, the file storage unit 13 stores the update information generated by the XML and the update file objectized for each unit file.

At this time, the update information includes various metadata such as a file name, file size (size), last modified date, file content (encrypted), etc. for each unit file. Accordingly, the update information allows the external update file downloading terminal 20 to select a target file to be updated from existing installation files. A comparison and analysis process between the update information performed by the update file downloading terminal 20 and the existing installation file will be described later in more detail with reference to FIGS. 3, 5, and 6.

Here, the update file for each unit file stored in the file storage unit 13 may be uploaded by a separate management server (not shown) located outside. That is, the external management server compresses each unit file according to an input signal from the service provider and uploads it to the update file providing server 10. In this case, the update file providing server 10 may be implemented according to a content delivery network technology.

3 is a diagram illustrating an embodiment of an update file downloading terminal according to the present invention.

As shown in FIG. 3, the update file downloading terminal according to the present invention includes a transmitter / receiver 21 for updating / transmitting various signals via an external device and the Internet, and file updating (that is, updating a program). Update request for an input unit 22 for receiving a signal related to data), a storage unit 23 for storing various operation programs, a system program, a file system, and the like and an arbitrary program selected through the input unit 22 The signal is transmitted to the external update file providing server 10 through the transmitting / receiving unit 21, and as a result of receiving the update information (an SMS file), the received update information and the selected program Compare and analyze the existing installation file and if there is a difference, a download request signal for the corresponding unit file is transmitted through the transmitter / receiver 21 File installation for performing the installation process for each unit file in parallel as the unit 24 receives the update file for each unit file from the update file providing server 10 through the transmitting / receiving unit 21. And a portion 25.

Here, looking at each operation process of the comparison analysis unit 24 in more detail, the comparison analysis unit 24 receives a signal related to the update for any program (eg game program) through the input unit 22 Accordingly, the update request signal for the corresponding program is transmitted to the update file providing server 10 through the transmitter / receiver 21.

Subsequently, as update information (an XL file) is received from the update file providing server 10, the update information and the existing installation file for the update target program are compared.

As a result of the comparison, if there is no difference, the program updating process is terminated. In practice, the update target program can be executed immediately. For example, when the update target program is an online game program, the update target program may be directly connected to the corresponding game server.

On the other hand, if there is a difference as a result of the comparison, the download request signal for the corresponding unit file is transmitted to the update file providing server 10. That is, the download request signal for the unit file corresponding to each of the existing installation files selected as the update target is transmitted to the external update file providing server 10 through the transmitter / receiver 21. The comparison process will be described later in more detail with reference to FIG. 6.

On the other hand, look at the operation of the file installation unit 25 in more detail, the file installation unit 25 is to download and process each unit file in turn through the transmission / reception unit 21 from the update file providing server 10 In addition, the downloading process and the decompression and copying process for each unit file are performed in parallel. For example, when a and b files are downloaded in order from the update file providing server 10, first, a decompression and copying process for the downloaded a file and a downloading process for the b file are performed in a parallel manner. can do. Here, the operation process of the file installation unit 25 may be implemented using multithread. This will be described later with reference to FIG. 8.

Then, the file installation unit 25 installs each file as the copying process for each decompressed unit file is completed.

The update file downloading terminal 20 described above refers to various terminals having a computing function, such as a personal computer, a notebook computer, a wireless communication terminal, and the like.

4 is a flowchart illustrating a method of transmitting an update file in an update file providing server according to the present invention.

Currently, in the file storage unit 13, update files uploaded from an external management server are stored for each unit file. Here, the meta data for each unit file is stored in the update information (an XL file).

First, the control unit 14 receives the update request signal from the update file downloading terminal 20 through the update request receiving unit 11 (401), and transmits the update information stored in the file storage unit 13 to the file transmitting unit. In step 402, the update file downloading terminal 20 transmits the update file to the downloading terminal 20. At this time, the update information is an XML file and includes a file name, file size (size), last modified date, file contents, and the like for each unit file.

Subsequently, as a download request signal for each unit file is received through the update request receiver 11 (403), the file unit 13 retrieves the corresponding unit file that has been requested to be downloaded from the file storage unit 13. Transmit via 404. That is, the unit file selectively requested by the update file downloading terminal 20 is transmitted as the update file. At this time, each unit file is in a compressed state.

5 is a flowchart illustrating an embodiment of a method for receiving an update file in an update file downloading terminal according to the present invention.

First, the comparison and analysis unit 24 receives a signal related to updating an arbitrary program (for example, a game program) through the input unit 22 (501), and transmits an update request signal for the corresponding program. The transmission unit 20 transmits the update file providing server 10 through the receiving unit 21 (502).

Then, as the update information is received from the update file providing server 10 (503), the comparison analysis unit 24 compares the received update information with the existing installation file (504).

As a result of the comparison (504), if there is no difference, the updating process is terminated (then, the program which is requested to update can be executed immediately), and if there is a difference, a request for downloading the corresponding unit file is found. The signal is transmitted to the update file providing server 10 through the transmitter / receiver 21 (505). In addition, after the file installation unit 25 performs a process for each unit file sequentially downloaded from the update file providing server 10 through the transmitting / receiving unit 21 (506), each file ( Each program executable file) is installed (507).

Here, a comparison process between the update information performed by the comparison analysis unit 24 and the existing installation file, and parallel processing for each unit file performed by the file installation unit 25 are shown in FIGS. 6 and 7, respectively. Looking in more detail with reference to the following.

FIG. 6 is a detailed flowchart illustrating a comparison process between existing information and update information for receiving an update file for each unit file in the update file downloading terminal of FIG. 5.

First, the comparison analyzer 24 receives update information from the update file providing server 10 through the transmitter / receiver 21 (601).

Here, the update information is an XML file and includes metadata about each unit file such as a file name, file size (size), last modified date, file contents, etc. for each item (including version information as metadata). May be). At this time, the file contents may be encrypted to prevent hooking by an illegal user or the like.

Thereafter, the comparison analysis unit 24 compares existing installation files and update information, and compares each item one by one (602) and determines whether there is an existing installation file in which one or more items that do not match exist (603). . That is, the existing installation file that has any difference is selected by comparing the file name, file size, last modified date, and file contents of each unit file (each unit file in which the update file is object) recorded in the update information. Determine whether or not it was done.

As a result of determining whether there is a difference 603, if there is no existing installation file having a difference from the update information, the updating process is terminated. In other words, since there is no existing installation file to update, the update process ends. Then, for example, when attempting to update the online game program, access to the game server.

Meanwhile, as a result of determining whether there is a difference (603), and if there is an existing installation file having a difference with the update information, a download request signal for the corresponding unit file corresponding to the existing installation file is transmitted through the transmitter / receiver 21. Transmit (604). In other words, it selectively finds existing installation files that need updating and downloads each unit file correspondingly. This results in more efficient use of network resources (e.g. less network traffic) than version-by-version (by filegroup) update file delivery, and avoids double downloads, resulting in time-consuming operations (compression and decompression). Time required for downloading, downloading time, etc.) can be shortened.

Here, a detailed operation process of downloading and processing the update file from the update file providing server 10 will be described in more detail with reference to FIG. 7 below.

7 is a detailed flowchart illustrating an update file processing process using multi-thread in an update file downloading terminal according to the present invention. Here, the thread is generated for each detailed processing.

First, the file installation unit 25 starts to download each unit file (program execution file) in order from the update file providing server 10 via the transmission / reception unit 21 (701). At this time, each unit file is in a compressed state.

Then, the file installation unit 25 generates a thread for each detailed processing, for example, each of the downloading process and the decompression / copy process, so that each detailed process is performed in parallel ( 703). For example, in case of downloading three program execution files a, b, and c from the update file providing server 10 in sequence, the file b is downloaded after the file a is downloaded and decompressed and copied. Each detailed processing is performed in parallel, such as by performing a downloading process for the b file, performing a decompression and copying process for the b file, and a downloading process for the c file. As a result, the work required time can be reduced as compared with sequentially performing each detailed processing process.

Of course, instead of creating a thread for the downloading process and the decompression and copying process, the process can be further divided into parallel processing.

Thereafter, the file installation unit 25 executes the downloaded program executable files. In other words, it updates the existing installation file that has been selected for updating.

8 is a diagram for explaining an embodiment of an XML file including update information according to the present invention. Here, update information for updating an installation file associated with a game will be described as an example.

As shown in FIG. 8, the update information according to the present invention is an XML file and includes metadata about a plurality of files. That is, the file name, file size (size), last modified date, and the like for each unit file are recorded. Of course, the file may be implemented to be compared with the file pre-installed in the update file downloading terminal 20 based on various criteria.

Here, since the metadata of the numerous files is recorded in the update information and the latest program execution file is generated and modified from time to time, it is preferable to manage the data using a separate tool for generating the XML file.

The present invention described above provides information on each unit file (the update file is each unit file in which the update file is an object) by using an XX (eXtensible Markup Language) standard language for data management and exchange. By selectively downloading the corresponding unit file corresponding to the existing installation file required, there is an effect of providing an update service more efficiently.

In addition, in performing various processing operations to install each program executable file, by using a multi-thread (multithread) in parallel, there is an effect that can reduce the installation time.

That is, the present invention has the effect of reducing the waste of resources when updating files and shortening the waiting time of the user to increase service satisfaction.

As described above, the method of the present invention may be implemented as a program and stored in a recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.) in a computer-readable form. Since this process can be easily implemented by those skilled in the art will not be described in more detail.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the technical spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited by the drawings.

The present invention as described above, by providing the update information by using the XML file, by comparing the update information and the existing installation file to be updated for each unit file, it can provide an update service more resource-efficient It works.

That is, the present invention selectively transmits / receives each unit file instead of transmitting / receiving the entire file group, thereby reducing download time and preventing time wasted due to unnecessary compression and decompression of files. There is. In addition, there is an effect that can reduce the waste of network resources for the transmission / reception of unnecessary files.

In addition, the present invention has the effect of reducing the file installation time by performing a variety of detailed processing for installing the update file in parallel using a multi-thread.
