Description

System and Method for Web Accelerating Service Using Cache for Subscriber}

The present invention relates to a web acceleration service system and method using a cache for each subscriber to enable a high-speed loading of cached files by managing a cache list in the server for each subscriber of a mobile communication terminal using a full browser.

In general, a web page data provided from a remote web server can be wirelessly transmitted to a mobile communication terminal using a mobile communication network and a wireless internet network so that the web page data can be displayed on the screen of the mobile communication terminal. Web browsing service is being applied.

The web browsing service through the wireless communication network receives a web document data of a specific URL from a web server on the internet network in a mobile communication terminal, and analyzes the web document through data rendering and parsing to format the web document. As a result, a full browser method for displaying on a screen is used.

That is, when a mobile terminal requests a web page of a specific URL to a proxy server through a full browser, the proxy server requests a web page and related files from a web server of the corresponding URL through an internet network, and the web server When the web page and the related file are received from the web server, file compression is performed on the text file using the web acceleration function of the proxy server, and compression is performed by reducing the image quality of the image file and provided to the mobile communication terminal.

In a full browser of a mobile communication terminal, a web browsing screen may be implemented on a screen by decompressing a compressed file received from a proxy server, parsing and rendering.

Meanwhile, in order to improve the loading speed of web pages and reduce unnecessary network transmission, the mobile communication terminal is capable of allocating and storing cache space in the memory of the terminal for cacheable file items.

When the file can be stored in the cache space allocated to the memory in the mobile communication terminal, the time for file transfer of the network is reduced and the loading speed of the web page can be partially improved.

However, since the current mobile communication terminal has a limited memory capacity, it is impossible to secure as much cache space as desired, so that it is difficult to cache many files. Therefore, only a limited number of web pages can be cached or cached. There is a problem in that it is difficult to expect visible results in shortening the network transmission time and improving the web page loading speed because the amount of content files that can be limited.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, and an object thereof is to store a cache file for each subscriber of a mobile communication terminal through a separate cache server and manage it through a cache list for each subscriber. It provides a web acceleration service system using a cache and a method thereof.

According to the system of the present invention to achieve the above object, in a web acceleration service system for receiving a web page file requested from a full browser of a mobile communication terminal from a web server for web acceleration processing, the full browser of the mobile communication terminal The web page file requested from the web server is compressed and converted, the converted file is transmitted to the cache server to be cached, and the cache list is generated and managed for each user of the mobile communication terminal. If the file requested from the full browser of the mobile terminal is cached in the cache server, the web accelerator server for receiving the converted file from the cache server and transmits to the mobile communication terminal, and the web compressed from the web accelerator server Cache the page file as well as caching By generating and managing a content cache list for the storage file, and receiving a cached file request from the web accelerator server, the cache server for each subscriber, comprising a cache server for providing the cache storage file to the web accelerator server Provide web acceleration service system.

According to the method of the present invention to achieve the above object, if a web page file of a specific URL is requested from the full browser of the mobile communication terminal, requesting the file to the cache server in the web accelerator server, and in the cache server Search whether the request file is cached based on a content cache list, and if the file is cached, transmit the file to the web accelerator server. If the file is not cached, the result is sent to the web accelerator server. In the transmitting, when the web accelerator server receives the file from the cache server, the file is transmitted to the mobile communication terminal. However, when the web accelerator server receives the result indicating that the file is missing, the file is received from the web server of the URL and compressed. Converting and transmitting the converted data to the mobile communication terminal; Updating a user cache list set for each user for the converted file received from a web server, transmitting the converted file to the cache server, and storing the converted file in the cache server and managing each cache file. It provides a web acceleration service method using a cache for each subscriber, characterized in that it comprises the step of updating the content cache list.

As described above, according to the present invention, it is possible to cache the file of the web page for each user of the mobile communication terminal through a separate cache server, and to manage the cached file through the user-specific cache list, It is possible to cache large amount of webpage files that user wants without being limited to the storage capacity, and the file transfer is not smooth due to the trouble of foreign website or line that takes a long time to receive the file from the web server. In this case, it is possible to smoothly provide a file of a web page, thereby improving the loading speed of the web page.

In addition, by allowing the cache server to cache the files that have been compressed and converted already, the web accelerator can save the time required for file conversion because the user does not have to convert the desired file at each time. As well as improving the loading speed of the web page, the user can feel the speed of using the Internet.

Hereinafter, the present invention configured as described above will be described in detail with reference to the accompanying drawings.

That is, FIG. 1 is a diagram showing the overall configuration of a web acceleration service system using a subscriber-specific cache according to the present invention.

As shown in FIG. 1, a web acceleration service system using a subscriber-specific cache according to the present invention includes a mobile communication terminal 10, a mobile communication network, a web accelerator server 20, and a cache server 30. , The Internet network, and a plurality of web servers A1 to An.

The mobile communication terminal 10 requests the web accelerator server 20 for web pages and related files desired by the user through a full browser, and compresses the compressed web page file provided from the web accelerator server 20. It releases it, parses it, and renders it to display the web browsing screen.

The web accelerator server 20 requests web page information of a specific URL requested from a full browser of the mobile communication terminal 10 to a corresponding web server, receives a related web page and a file, performs compression processing, and moves the web page. It transmits to the communication terminal 10, which requests a file to the cache server 30 on the basis of a subscriber-specific cache list set in advance when a web page file request from the mobile communication terminal 10 is requested. The cache server 30 receives the cached file and transmits the cached file to the mobile communication terminal 10.

Here, if the file requested by the mobile terminal 10 is not cached in the cache server 30, the web accelerator server 20 requests and receives a file from a web server of the requested URL and compresses the file. The file information is updated in the cache list for each subscriber, and the file list and the compressed and converted file are provided to the cache server 30 to be cached.

The cache server 30 caches and stores web page related files included in the subscriber-specific cache list set in the web accelerator server 20, sets and manages a content cache list of cached files. have.

When the cache server 30 receives the file updated in the subscriber-specific cache list of the web accelerator server 20 and the deletion, addition of the file list of the file, the cache server stores the corresponding file and updates the content cache list. Let's go.

The plurality of web servers A1 to An hold web pages according to respective websites, and provide web pages and related files of URLs requested from the web accelerator server 20.

Next, FIG. 2 is a diagram exemplarily illustrating a state in which a cache file is managed through a cache list of a web accelerator server and a cache server according to a preferred embodiment of the present invention.

As shown in FIG. 2, the web accelerator server 20 generates and manages a user cache list for each subscriber of a mobile communication terminal equipped with a full browser, and the user cache list of the mobile communication terminal possessed by the user. Each terminal is managed by phone number, and each user manages URL information of a cached file, file size, expiration date, and last access date.

The cache server 30 generates and manages a content cache list of cached content files, and each cache file is stored in the content cache list using URL information as an index. A reference count is given for.

Here, the reference count adds the count value when there is a request for adding a file from the web accelerator server 20, and subtracts the count value when there is a delete request, and when the count value is "0", the cache is stored. The file will be deleted.

The web accelerator server 20 provides a content file to be cached to the cache server 30, and provides a list of files for deletion and addition of each content file to provide the content cache list. Update and cause the count value of the reference count to increase or decrease.

Next, the operation of the present invention made as described above will be described in detail with reference to the flowcharts of FIGS. 3 and 4.

First, an operation relationship when there is no cached file in the cache server will be described with reference to the flowchart of FIG. 3.

The cache server 30 searches for a file requested by the web accelerator server 20 with reference to a preset content cache list, and if the file is not stored, the cache server 30 notifies that the file is not cached. The web accelerator server 20 transmits to the web accelerator server 20 (step S12), and the web accelerator server 20 requests a file from the cache server 30 to the web server of the corresponding URL (step S13).

Accordingly, the web server transmits the webpage file requested by the web accelerator server 20 (step S14), and the web accelerator server 20 compresses and converts the file received from the web server. If the text file is a compression process according to a conventional compression algorithm, and if the file is an image file, compression is performed using image loss processing to reduce the size of the image (step S15).

The web accelerator server 20 transmits the compressed file to the full browser of the mobile communication terminal 10 (step S16), and decompresses the file in the full browser of the mobile communication terminal 10. Parsing and rendering are performed to be displayed as a web browsing screen (step S17).

Meanwhile, the web accelerator server 20 updates the file information (URL, file size, expiration date, last access date, etc.) of the converted file by adding it to a user cache list. If the capacity of the cache list is exceeded, the oldest cache file information is deleted by determining the expiration date in the list (step S18).

In addition, the web accelerator server 20 transmits the converted file and a list of files to be deleted and added according to the user cache list to the cache server 30 (step S19), and the cache server ( 30) additionally caches the converted file to be transmitted, and updates the content cache list with reference to the file list. If the file list includes file information to be deleted, the corresponding file item of the corresponding content cache list. If the reference count value is reduced, but the reference count value is " 0 ", the corresponding file is deleted (step S20).

Meanwhile, the cache server 30 transmits the result of storing the converted file and updating the content cache list to the web accelerator server 20 (step S21), and the web accelerator server 20 transmits the cache server 30. Then, the user cache list is updated again according to the file processing result from step S22.

Next, the operation in the case where there is a cached file in the cache server will be described with reference to the flowchart of FIG. 4.

First, when a web page file of a specific URL is requested from the full browser of the mobile communication terminal 10 (step S30), the web accelerator server 20 corresponds to the cache server 30 based on a preset user cache list. The web page file is requested (step S31).

The cache server 30 searches for a file requested by the web accelerator server 20 with reference to a preset content cache list, and if it is determined that the file is cached, extracts the file (step S32). The data is transmitted to the accelerator server 20 (step S33).

The web accelerator server 20 transmits the file as it is to the full browser of the mobile communication terminal 10 since the file received from the cache server 30 is a converted file already compressed (step S34), The full browser of the mobile communication terminal 10 decompresses the file and parses and renders it so that it can be displayed as a web browsing screen (step S35).
