Description

Web browser system of mobile communication terminal using proxy server {A WEB BROWSER SYSTEM USING PROXY SERVER OF A MOBILE COMMUNICATION TERMINAL}

The present invention relates to a technology for improving the speed of a web browser for a mobile communication terminal, and in particular, a proxy for improving the speed of a web browser using a proxy server when accessing Internet information through a web browser in a mobile communication terminal. A web browser system of a mobile communication terminal using a server.

In recent years, the web browser in mobile communication terminals such as mobile phones has become an essential tool for accessing the Internet from the terminal, and its importance is further increased thanks to the activation of the wireless Internet. Recently, the supply of smartphones equipped with an operating system (OS) capable of implementing complex functions, such as increasing the screen size of the mobile communication terminal, improving the performance of the central processing unit (CPU), and implementing complex functions is greatly increased. It is increasing. Accordingly, there is an increasing demand for users who want to use complex web sites such as PCs using the HTML standard, as well as web sites dedicated to very simple mobile phones using the existing WAP standard.

In the existing web browser method applied to mobile communication terminals such as mobile phones, a method such as Internet Explorer, iPhone Safari, Opera Mobile, etc. is mainly used by a terminal. This independent web browser has the advantage of simple system implementation, but when accessing complex web pages larger than 1MB, 8 seconds or more is required for data transmission in the wireless network under the current wireless bandwidth of 1Mbps. As a result, the overall processing speed of the web browser is greatly reduced.

Recently, in order to make up for this drawback, a method of installing a proxy server between a mobile communication terminal and a web content server to be finally accessed and processing information using the same has been proposed. As a representative example of this, there is a "WebView" method such as "Logic Plant". The web view method is a method of greatly improving the speed of viewing a web page on the terminal by transmitting a browser result processed in a proxy server to the terminal as a small data size image.

However, such a web view method is difficult to process a video since it is based on a simple image. In addition, when accessing an interactive web application using AJAX, information is processed based on a proxy image, and thus, the response speed is significantly reduced. In addition, since the proxy server handles all of the web browser functions, there is a problem in that the cost burden is greatly increased because the proxy server must be greatly expanded in response to the increase in the number of terminal users using these functions.

Therefore, a fast and effective web browser in a mobile communication terminal is required to compensate for the shortcomings of the conventional independent web browser and the proxy web browser until the bandwidth of the wireless network and the performance of the terminal are greatly improved. have.

In addition, web pages frequently visited by users have more than 100 files. Therefore, how fast a large number of files composing a web page to a terminal is an important factor in determining the web browser performance of a wireless terminal with limited network bandwidth. Therefore, in order to improve the web browser speed of a mobile communication terminal having a large speed difference from a PC browser, a technology for quickly delivering a file constituting a web page to a terminal is required.

Accordingly, an object of the present invention is to improve the processing speed of a web browser of a mobile communication terminal by reducing the amount of wireless transmission data by using binary encoding of a proxy in the mobile communication terminal.

Still another object of the present invention is to improve the web browser processing speed of a mobile communication terminal by quickly obtaining files of a web page to be accessed and transferring them to the mobile communication terminal using a prefetching technique in a proxy server.

The objects of the present invention are not limited to the above-mentioned objects. Other objects and advantages of the invention will be more clearly understood by the following description.

The present invention for achieving the above object,

And a web server for transmitting a file constituting a web page such as HTML, CSS, JavaScript, an image file, etc. to the proxy server according to the access command received from the proxy server.

Another invention for achieving the above object is,

And a proxy server for transmitting a file of the web page pre-fetched when the web browser requests a previously requested web page again.

And a web server for transmitting a file constituting a web page such as HTML, CSS, JavaScript, an image file, etc. to the proxy server according to the access command received from the proxy server.

Another invention for achieving the above object is,

For web browsing of the embedded web browser, HTML and CSS binary files received from the proxy server are decoded and parsed, JavaScript byte code is executed, and image files are decoded and rendered for each of these results. A mobile communication terminal having a local prefetching module and previously transmitted before executing a file prefetched to a proxy server;

Receives a main file from a web server corresponding to the web address received from the mobile communication terminal and transmits the main file to the mobile communication terminal, and receives a file linked to the main file from the web server and transmits the file to the mobile communication terminal. And a proxy server for transmitting a file of the web page pre-fetched when the web browser requests a previously requested web page again.

And a web server for transmitting a file constituting a web page such as HTML, CSS, JavaScript, an image file, etc. to the proxy server according to the access command received from the proxy server.

The present invention allows the proxy server to perform functions such as grammar recognition based encoding of HTML / CSS, JavaScript bytecode conversion, image file quality conversion, etc., thereby greatly reducing the amount of data transmitted from the mobile communication terminal. Accordingly, the browser speed in the mobile communication terminal using the limited wireless bandwidth is greatly improved.

In addition, since only the grammar interpretation and file conversion are performed by the proxy server and all other browser functions are performed by the mobile terminal, the cost of the proxy server is reduced, and video playback and web application using AJAX can be easily performed. .

In addition, the pre-fetching method of receiving web page files to be accessed in a limited wireless network bandwidth environment using a proxy server and supplying them to the web browser of the mobile communication terminal improves the processing speed of the web browser of the mobile communication terminal. do.

In addition, by compressing and caching a file in the proxy server and delivering the file to the mobile communication terminal, the storage device of the proxy server is reduced and the file can be delivered more quickly through the wireless network, thereby improving the performance of the web browser.

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

FIG. 1 is a block diagram of a web browser system of a mobile communication terminal using a proxy server according to the present invention. As shown in FIG. 1, the mobile communication terminal 110, a proxy server 120, and a web server 130 are provided.

First, when a user inputs a web address to be accessed on a web browser of the mobile communication terminal 110, it is transmitted to the proxy server 120 through a wireless network and the Internet.

The proxy server 120 receives the web address from the mobile communication terminal 110 and transmits an access command of the web page to the web server 130 of the address. The access command is a command following the HTTP protocol.

In response to the access command received from the proxy server 120, the web server 130 stores a file constituting a web page such as HTML, Cascading Style Sheet (CSS), JavaScript, or an image file. To be sent).

The proxy server 120 receives HTML, CSS, JavaScript, image files, etc. from the web server 130 to perform HTML grammar recognition binary encoding, CSS grammar recognition binary encoding, JavaScript bytecode generation, and image quality conversion functions. do. Thereafter, the proxy server 120 transmits the converted contents to the mobile communication terminal 110 through a wireless network.

In this case, the HTML, CSS, and image files may be continuously transmitted to the mobile communication terminal 110 while being converted by the proxy server 120. Therefore, the mobile communication terminal 110 can receive and process data during conversion of the HTML, CSS, and image files, thereby reducing the processing time of the web browser.

The web browser of the mobile communication terminal 110 performs decoding, parsing, and rendering on the HTML and CSS binary files transmitted from the proxy server 120, and performs image processing (engine) and rendering on the received image files. The received JavaScript bytecode is executed by the JavaScript bytecode execution engine, and the image file is executed by the image file decoding engine. The results thus processed are displayed on the display device of the mobile communication terminal 110.

Preferably, the network connecting the web server 130 and the proxy server 120 is a network having a very high transmission speed having a wired broadband bandwidth, and a network connecting the proxy server 120 and the mobile communication terminal 110. Is a wireless network such as mobile communication, Wi-Fi, or WLAN, which has a relatively slow transmission speed.

However, the proxy server 120 converts web page elements such as HTML, CSS, images, and JavaScript files into files having a smaller capacity than the original file, and transmits them to the mobile communication terminal 110 through a narrow bandwidth wireless network. . Accordingly, it is possible to obtain substantially the same effect as extending the bandwidth of the wireless network.

For example, the Naver website “http://www.naver.com”, one of the most visited websites in Korea, has a total file size of about 1MB. The 1MB file consists of about 200KB of HTML, about 50KB of CSS, about 250KB of JavaScript, and about 500KB of image files.

The proxy server 120 recognizes the grammars of the HTML and CSS and encodes them into a binary file, thereby reducing the size of the file to the original 1/4 level. The proxy server 120 interprets the JavaScript and generates bytecode accordingly, thereby reducing the capacity of the original JavaScript file to a quarter level. The proxy server 120 lowers the image quality of the image file so that its capacity is reduced to a quarter of that of the original.

By doing so, the 1MB file transmitted to the proxy server 120 is converted into 250KB, which is 1/4, and transmitted to the mobile communication terminal 110.

When the mobile communication terminal 110 uses a network of 1 Mbps wireless bandwidth, it takes 8 seconds to transfer a 1 MB file to the mobile communication terminal 110.

On the other hand, when the 1MB file is transmitted to the mobile communication terminal 110 through the proxy server 120 and the network, the capacity of the file is reduced to 250KB through the above process, and the transfer time is also original 1 Decrease to 2 seconds of 4

Thus, substantially the same effect as the wireless bandwidth is increased by four times. As a result, the processing speed of the web browser on the mobile communication terminal 110 is improved accordingly.

In addition, since the web browser of the mobile communication terminal 110 processes the web content files processed as described above in the proxy server 120, the processing speed is improved due to the following reasons.

Since the web browser uses a binary encoding scheme based on grammar recognition for HTML and CSS files, there is no need to perform a function for recognizing grammar of HTML and CSS files as in the prior art. In the case of JavaScript, since it is already interpreted in the proxy server 120 and transmitted to the web browser in the form of bytecode, it can be executed immediately without the need for interpretation in the mobile communication terminal 110. Since the image file is reduced in image quality and transmitted to the mobile communication terminal 110, the processing speed of the image file decoding engine is improved.

In general, the proxy server 120 has a central processing unit that is very excellent in performance compared to the mobile communication terminal 110. In view of this, the proxy server 120 performs functions such as grammar analysis, thereby reducing the load of the web browser of the mobile communication terminal 110.

In a conventional information processing method such as WebView, all internal functions of the web browser are performed by the proxy server, and only the result is transmitted to the mobile communication terminal. Therefore, it is difficult to play a video at a normal speed, and has a fatal flaw such as increased response time when accessing a web application using AJAX (Asynchoronous JavaSrcipt and XML). In contrast, in the proxy method of grammar recognition binary encoding according to the present invention, since only the grammar interpretation and file conversion are performed in the proxy server 120 and all other browser functions are performed in the mobile communication terminal 110, the brother and sister play and AJAX are performed. It does not have the problem of accessing the web application used.

2 is a detailed block diagram of a web browser in the mobile communication terminal 110. As shown therein, the HTML binary decoder 211 and the HTML parser 212, the CSS binary decoder 221, and the CSS parser ( 222, a JavaScript bytecode execution engine 231, an image file decoding engine 241, and a renderer 251.

The HTML binary, CSS binary, JavaScript bytecode, image file, etc. received by the mobile communication terminal 110 from the proxy server 120 through the wireless network are processed by the corresponding block as described below.

The HTML binary decoder 211 decodes the grammar recognition encoded HTML binary and restores the original HTML. The HTML parsing unit 212 parses the restored HTML to be suitable for the rendering process.

The CSS binary decoder 221 decodes the grammar recognition encoded CSS binary and restores the original CSS. The CSS parsing unit 222 parses the restored CSS to be suitable for the rendering process.

The JavaScript bytecode execution engine 231 receives the JavaScript bytecode and executes it.

The image file decoding engine 241 receives the image file and executes it.

The rendering unit 251 renders the HTML, CSS, JavaScript, and image files executed as described above and outputs them to the display device in the mobile communication terminal 110.

Here, the HTML binary decoder 211 performs the opposite function of the HTML grammar recognition binary encoding performed by the proxy server 120. Since the grammar interpretation for HTML has already been performed in the proxy server 120, the lexing ( Lexing can be omitted.

However, since grammar interpretation and parsing are typically implemented in one block, lexing can be performed along with parsing by restoring the original HTML.

Similarly, the CSS binary decoder 221 may selectively determine whether or not to perform lexing in the same manner as the HTML binary decoder 211.

FIG. 3 is a block diagram of binary encoding of an HTML source based on grammar recognition in the proxy server 120. As shown therein, a data type recognition encoder 311, a tag recognition encoder 321, and a similar URI are shown. It comprises a collector 331 and a file compressor 332, a file compressor 341, a collection and streaming output unit 351.

The HTML source input to the proxy server 120 is composed of data types, tags, URIs, and contents, each of which is encoded and collected according to respective characteristics within the proxy server 120. The collected data may be transmitted in a streaming manner for quick delivery to the mobile communication terminal 110.

The data type recognition encoder 311 recognizes the data type in the input HTML source and encodes the binary code.

The tag recognition encoder 321 recognizes a tag in the input HTML source and encodes the binary code.

The similar URI collection unit 331 collects a similar URI (Uniform Resource Identifier) from the input HTML source. The file compressor 332 compresses the URI collected and transmitted by the pseudo URI collection unit 331 to a file compressor such as GZip having a high compression rate and outputs the binary code.

The file compressor 341 compresses the content data of the input HTML source with a general file compressor such as GZip and outputs the binary data.

The collecting and streaming output unit 351 collects each piece of information output as a binary code through each unit and outputs an HTML binary code in a streaming form.

Meanwhile, the encoding algorithm of the proxy server 120 will be described in more detail through examples.

The data type is data representing numbers, color information, and the like in the HTML source. The data type is encoded and compressed into binary, which is a method for reducing the amount of data by converting a number represented by a character into an integer. For example, in the case where width = “100” representing the width of an image, “100” has 5 characters because it has 5 characters. However, if 100 is expressed as an integer, it is converted into 1 byte information, so 5 byte data can be converted into 1 byte data. In such a case, it is necessary to allocate the amount of bytes needed to represent the size of the number represented by the character.

As an encoding method for the HTML tag, a method of encoding using a subsequent tag according to the preceding tag is used. For example,

<ul>

<li>

If the tag <ul> is followed, only three <li>, </ li>, and </ ul> tags. Therefore, since only 2 bits can be coded for the following <ul>, 4 bytes for <li> can be reduced to 2 bits. On the other hand, if there are a large number of subsequent tags, the probability of a subsequent tag coming out can be known in advance through analysis of several web pages, so specify a short bit for a large number of tags and a long list for a small number of tags. By applying a bit designation method, it is possible to reduce the amount of data for representing a tag.

URI indicating URL / URN mainly indicates external resource address including image file. When the mobile communication terminal 110 obtains an image file from the web server 130, the mobile communication terminal 110 is mainly imported from web servers having similar addresses. For example, if you look at the URI information in the HTML of “http: www.naver.com”,

http://www.naver.com/image/a.jpg

http://www.naver.com/image/b.jpg

http://www.naver.com/image/c.jpg

Most of the address information has similar characteristics. By the way, in the case of the portal site such as http://www.naver.com has a lot of external resources, there is a feature that there is a lot of URI data as described above.

In view of this, in the present invention, as described above, the similar URI collection unit 331 collects similar URIs. Then, the file compressor 332 compresses the URI collected and transmitted by the pseudo URI collection unit 331 to a file compressor 332 having a high compression ratio such as Gzip and outputs the binary code. As a result, a binary having a high compression ratio can be obtained for the URI. In particular, the more similar URIs, the higher the compression rate.

FIG. 4 is a block diagram of binary encoding of a CSS source based on grammar recognition in the proxy server 120. As shown therein, a data type recognition encoder 411, a block recognition encoder 421, a pseudo URI It consists of a collector 431, a file compressor 432, and a collector and streaming output 444.

The data type recognition encoder 411 recognizes the data type in the CSS input from the web server 130 and encodes it into binary code.

The block recognition encoder 421 recognizes a script block in CSS input from the web server 130 and encodes it into binary code.

The similar URI collection unit 431 collects a similar URI in CSS input from the web server 130. The file compressor 432 compresses the URI collected and transmitted by the pseudo URI collection unit 431 into a general file compressor and outputs the binary code.

The collection and streaming output unit 441 collects each piece of information output as a binary code through each unit, and outputs a CSS binary code in a streaming form.

The CSS grammar recognition binary encoding structure of FIG. 4 is similar to the structure of binary encoding of the HTML source of FIG. 3 based on grammar recognition except that the syntax is different and there is no content.

Files such as flashes other than HTML, CSS, JavaScript, and image files are transmitted to the mobile communication terminal 110 without modification in the proxy server 120 or compressed and transmitted through a conventional file compressor. In contrast, the web browser of the mobile communication terminal 110 receives and processes the transmitted file.

5 is a prefetching block diagram of a terminal web browser using a proxy server according to another embodiment of the present invention. As shown in FIG. 5, a mobile communication terminal 510, a proxy server 520, and a web server 530 are configured. do.

The mobile communication terminal 510 includes a web browser 511 and is connected to the proxy server 520 through a wireless network.

The proxy server 520 includes a prefetching module 521 and is connected to the web server 530 through a broadband wired network.

The web server 530 embeds contents such as a web page.

The proxy server 520 receives the web address from the mobile communication terminal 510 and transmits a web page access command to the web server 530 of the corresponding address. In response, the web server 530 transmits the main HTML file of the web page to the proxy server 520. Accordingly, the proxy server 520 receives the main HTML file and transmits the main HTML file to the web browser 511 of the mobile communication terminal 510. In addition, the proxy server 520 analyzes the main HTML file and transmits a corresponding command to the web server 530 to receive the linked file. In this regard, the web server 530 transmits the linked file to the proxy server 520, and the proxy server 520 immediately delivers the file to the mobile communication terminal 510 to be processed by the web browser 511. Do it.

Prefetching in the proxy server 520 is associated with caching and compression. The files received from the web server 530 may be cached by the proxy server 520. Therefore, when the web browser 511 requests the proxy server 520 the same web page as the web page previously requested, the file cached in the proxy server 520 may be immediately used.

In this case, the proxy server 520 compresses the file of the prefetched web page by binary encoding and transmits the file to the web browser 511 through a wireless network, thereby reducing the capacity of the transmitted file. As a result, the processing performance of the web browser 511 is improved, and the capacity of a storage device such as a hard disk can be reduced.

For example, the NAVER website http://www.naver.com, one of the most visited websites in Korea, has about 200 total files that the web browser 511 should receive. to be.

When a user enters the http://www.naver.com address in the web browser 511 of the mobile communication terminal 511, the proxy server 520 receives the address and the web page is transmitted from the web server 530. Send the access command. Accordingly, the web server 530 transmits the main HTML (main.html), main JavaScript (main.js), and main CSS (main.css) files of the web page to the proxy server 520.

At this time, the proxy server 520 transmits mail.html, main.js, and main.css files to the mobile communication terminal 510, and analyzes the files to find the addresses of the linked files, Send the file access command to the web server to receive 200 linked files. The proxy server 520 transmits the received file directly to the web browser 511 of the mobile communication terminal 510 to be executed.

Accordingly, the waiting time is significantly reduced compared to that of the web browser 511 requesting and receiving the files from the proxy server 520.

The proxy server 520 analyzes and changes the JavaScript code that does not affect the HTML page layout to be located behind the HTML, thereby reducing the initial page rendering time of the page in the mobile communication terminal 510. . This improves the user's haptic responsiveness.

For example, it takes about 4 seconds to encrypt the user password at the mobile terminal 510 when logging in to the NAVER site. During this process, the web browser 511 cannot perform other layout tasks. Therefore, the time taken for the user to first check the contents of the page is increased by about 4 seconds. Similarly, you can change JavaScript code that acts on HTML elements that are invisible before the user enters it, or code that is common to all pages but not used on the current page. As an example, there are tool functions used to implement controls such as web editors, and encryption codes for user login are included in this class.

If you can see that this kind of code does not affect the page layout, you can place the code backwards so that the user can see the contents of the page faster. This can be done by analyzing the class and attribute attributes of the HTML tag and the CSS and JS files and JavaScript tags in the HTML file to which the HTML file refers.

For JavaScript code that affects page layout, it is largely 1) code to add or change sub-attributes to style elements of HTML elements, 2) code to add or change class attributes of HTML elements, 3) Create a new element through the createElement function of the document element and add it using the appendChild function of another element, or remove a child item with removeChild of the HTML element. 4) Change the innerHTML attribute of the HTML element. The code can be divided into four categories.

To identify code that performs a lot of calculations without affecting page layout, look for code that does a lot of work on for control statements, while control statements, arrays, or strings that don't fall into the four categories above. Find them together and check that they don't fall into these four categories.

Code commonly included on your site's HTML pages, but not currently used in HTML, is often written in the form of functions, which can be placed backwards if nothing is called. The code for the invisible part can be identified by first identifying the HTML elements whose CSS visible or display properties are hidden / none, and then identifying the code that does not change their visible or display properties.

6 is a block diagram of prefetching processing using local prefetching in a web browser of a mobile communication terminal according to the present invention.

The web browser 511 of the mobile communication terminal 510 embeds the local prefetching module 511A and transmits a command for receiving the prefetched web page file to the proxy server 520 before execution.

Local prefetching in the web browser 511 is performed similar to prefetching in the proxy server 520.

That is, the local prefetching module 511A of the web browser 511 analyzes the main file of the web page to be accessed, recognizes address link information of the file to be transmitted, and accesses based on the recognized address link information. A command is generated and transmitted to the proxy server 520.

Accordingly, the files are transmitted from the caching module 523 of the proxy server 520 to the local prefetching module 511A. The local prefetching module 51A transfers the received files to the web browser 511. To pass).

7 is a block diagram illustrating embedding and merging processing of a picture file using a proxy server.

HTML refers to several pictures using <img> tags or CSS, and the web browser 711 of the mobile communication terminal 710 must receive all pictures referenced in the HTML through a separate HTTP request / response from the browser. Since the wireless network between the mobile communication terminal 710 and the proxy server 720 has a low communication speed, the loading speed decreases as the number of HTTP requests from the web browser 711 increases.

The proxy server 720 includes a small image without duplication in the form of a data URL in the HTML file or combines several pictures into one picture. Accordingly, the number of HTTP requests / responses required for picture display is reduced, and the page loading speed of the web browser 711 of the mobile communication terminal 710 is improved.

As described above, when integrating multiple pictures into a single picture, it is preferable to modify HTML and CSS codes referring to the integrated image so that only the part corresponding to the original image is imported.

8 is a block diagram illustrating automatic detection of HTML encoding using a proxy server.

In general, the web browser 811 at the mobile terminal 810 typically must use an encoding autodetector to correctly display the HTML file for which no encoding is specified. In addition, in order to increase the accuracy of automatic detection, more time should be used for encoding detection, and the web browser 811 of the resource-constrained wireless mobile communication terminal 810 has a limitation in using much time.

In view of this, in the present invention, the encoding server 820 performs encoding automatic detection using the encoding automatic detector 821. By doing so, the rich resources of the proxy server 820 can be used to more accurately detect the encoding in less time. In addition, since the encoding detection function is not performed in the web browser 811 of the mobile communication terminal 810, the usage time of the battery power is extended accordingly.

Although the present invention has been described in more detail with reference to Examples, the present invention is not necessarily limited to these Examples, and various modifications can be made without departing from the spirit of the present invention. Therefore, the embodiments disclosed in the present invention are not intended to limit the technical idea of the present invention but to describe the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments. The protection scope of the present invention should be interpreted by the following claims, and all technical ideas within the scope equivalent thereto should be construed as being included in the scope of the present invention.
