The present invention improves the data transmission speed of the swap type wireless Internet. In particular, since the image data of the HTML document is received from the WAP gateway and converted into binary data for streaming, the web document image data is transmitted to improve the rendering speed. The present invention relates to a speed improvement system and an operation method.

In general, WIRELESS APPLICATION PROTOCOL (WAP) technology is called a wireless application protocol and accesses the Internet in mobile communication systems such as CELLULAR communication or pager (PAGER), such as e-mail, web, news and IRC. Is a standardized communication protocol for standardizing the way a mobile communication terminal can access the Internet in a mobile state, and has compatibility and interoperability between WAP-enabled devices and service systems. will be.

LAYER operating in WAP includes Wireless Application Environment (WAE), Wireless Session Layer (WSL), Wireless Transport Layer Security (WTLS), and Wireless Transport Layer (WTP).

HTTP or HTTPS stands for Secure Hypertext Transfer Protocol, developed by Netscape, and is a web protocol implemented in a web browser that encrypts and decrypts the user's pages and the pages returned by the web server.

HTTP supports the use of digital certificates from servers, so users can trust the sender.

Also, HYPERTEXT MARKUP LANGUAGE (HTML) is a set of code included in a markup symbol or file for displaying information on a web browser, and is defined by the W3C.

MARKUP is a way of telling a web browser how to display characters or images within a web page, and HTML is an open format based on SGML (STANDARD GENERALIZED MARKUP LANGUAGE). Text can be created and edited. The title, paragraph, list, hyperlink, etc. of the web document all use tags, and the tags begin with a "<" mark and end with a ">" mark. For example, to display a hyperlink: <A HREF = "hyperlink address">, and to adjust the text size: <h1> South Korea </ h1>, and to insert an image: <img src = "related.gif "width =" 235 "height =" 14 ">, and so on.

In order to use the Internet's swap service as a terminal, the HTTP protocol is used. Web documents are created by HTML.

Hereinafter, with reference to the accompanying drawings will be described the Internet web document download method by the swap of the terminal according to the prior art.

1 is a functional configuration of a swap system according to the prior art, wherein the terminal 10 is freely moved in a service area constantly formed by the mobile communication network 20 and wirelessly connected to a desired counterpart to communicate with a voice signal and a data signal. Or, access the web server of the Internet, search and download the web document including text, image and video, download and check, upload the created document and upload the web server. Post to.

The mobile communication network 20 forms a service area through which the terminal 10 can freely move and communicate while wirelessly connecting. When the call connection request is made, the mobile communication network 20 sets the communication path to be switched to connect.

The WAP GATEWAY 30 provides a path through which the terminal 10 and the web server 40 of the Internet (INTERNET) are connected under the control of the mobile communication network 20, and the protocol PROTOCOL is in a consistent state. Convert it as much as possible.

The web server 40 provides a variety of information composed of HTML. The web server 40 connects at the request of the terminal 10, downloads and provides a searched web page or web document, or posts a web document uploaded by the terminal.

Referring to FIG. 2, a signal flow state of the conventional swap system is described. The terminal 10 is connected to the swap gateway 30 connected to the mobile communication network 20 with the web server 40. When requesting to open a session (SESSION) for data communication (S10), the swap gateway 30 searches for resources and allocates the session if there is a session to allocate, and sends a response signal (S20).

After confirming that the session is allocated, the terminal 10 requests the swap gateway 30 to download the retrieved HTML document from the designated web server 40 (S30). The received swap gateway 30 receives the request from the designated web server. The user accesses 40 to download the searched HTML document (S40).

The web server 40 returns the retrieved HTML document to the swap gateway 30, and the swap gateway 30 returns the terminal 10 to the mobile communication network 20.

The terminal 10, which has received the retrieved HTML document, parses the HTML document (S70).

The terminal 10 parses the HTML document in this way, classifies it into an image including text and video, and converts the text into a corresponding format and displays it on the display unit of the terminal.

As an example, it is assumed that as a result of parsing an HTML document, it is confirmed that two images are included.

Since the image is recorded as a separate URL address, the terminal accesses the swap gateway 30 and requests the image 1 (S80) for the verified image 1, and the swap gateway 30 receives the request again. Access to the web server 40 requests the image 1 (S90), the web server 40 returns the data of the retrieved image 1 to the swap server 30 (S100).

The swap gateway 30 that has received the image 1 in this manner transfers the data of the image 1 that has been returned to the terminal 10 (S110).

In addition, the terminal 10 accesses the swap gateway 30 using the URL address of the image 2 to request data of the image 2 (S120), and the swap gateway 30 accesses the web server 40 to the image 2 Request (S130).

The web server 40 returns the retrieved image 2 data to the swap gateway 30 (S140), and the swap gateway 30 transmits the data of image 2 to the terminal 10 (S150).

Since the terminal 10 checks all the contents of the webpage to be searched, the terminal 10 requests the swap gateway 30 to close the allocated session CLOSE (S160), and the swap gateway 30 checks the contents of the session. The response signal is returned with the end process (S170).

Therefore, in the conventional technology of such a configuration, since the terminal parses the HTML of the web document and accesses the URL address of the included image again and requests the corresponding image, the procedure becomes very complicated and time-consuming when there are many images. At the same time, there is a problem that the load on the terminal increases.

Hereinafter, according to an embodiment of the present invention, a method of operating a web document image data transmission speed improving system will be described. In order to wirelessly connect to the Internet in a mobile state, the terminal 100 moves in a WAP method. The communication network 110 is connected to the swap gateway 120 by the communication path set by the mobile communication network 110.

The terminal 100 requests the swap gateway 120 to open an open session for connecting to the web server 130 of the Internet and communicating data.

The swap gateway 120 opens a session SESSION for data transmission, allocates it to the terminal 100, and notifies the terminal of the processing result in response.

The terminal 100 accesses a designated web server 130 of the Internet in a swap method supported by the swap protocol through a session opened and allocated by the swap gateway 120 and retrieves unlimited information.

The terminal 100 requests the swap gateway 120 to provide the designated HTML web document from the designated web server 130, and the swap gateway 120 accesses the designated web server 130 to provide the designated HTML web document. We ask you to give it back, so we get an HTML web document back.

Since the HTML web document returned as described above is parsed by the WAP gateway 120, the HTML web document is classified into a TEXT document and an IMAGE document. In general, a plurality of image documents are included in one HTML web document. If included, each image is represented by a URL address.

Since the URL address is accessed, the image data can be provided.

The swap gateway 120 accesses the web server 130 by using the corresponding URL address according to a predetermined order in which a plurality of classified images are set, and requests the provision of the image and is provided as a reply.

This process is repeated until all of the image data is returned from the URL addresses for the multiple images classified as parsed by the swap gateway 120.

After all of the image data is returned from the web server 130, the swap gateway 120 performs a packet RESULT process.

In the packet restart process, all text documents included in a specified HTML web document are placed at the beginning of the packet, and an image document is placed at the rear.

Referring to FIG. 5, the structure of the packet stop is shown in detail.

Using the packet reset structure configured as described above provides the text data of the designated HTML web document first, so that the text is displayed first in the terminal 100, and the image data which displays a large amount of data and takes a long time for rendering is displayed. Find time to become a member.

The swap gateway 120 returns the packet request to the terminal 100 through an open session, and thus is output through the corresponding output function unit of the terminal 100.

After checking the desired HTML web document, the terminal 100 requests the swap gateway 120 to terminate the session, so that the session allocated by the swap gateway is recovered and terminated.

The procedure of this process will be described in detail with reference to FIG. 4, and the terminal 100 requests the opening of the session to the swap gateway 120 (S200), and the swap gateway 120 selects and assigns an assignable session. In response to the processing result, the terminal 100 returns a response (S210).

The terminal 100 requests the swap gateway 120 to provide the designated HTML web document (S220), and the swap gateway 120 requests the designated HTML document by accessing the designated web server 130 (S230). In step S240, an HTML document is provided from the web server 130 as a reply.

The HTML document returned in this way is parsed by the swap gateway 120, and thus classified into text TEXT and image IMAGE (S250).

In general, a number of images that have been parsed and classified are described as two in the description of the present invention, and each classified image is composed of a URL address.

The swap gateway 120 accesses the web server 130, requests the corresponding image 1 from the URL address of the image 1 (S260), and receives the reply (S270).

In addition, the swap gateway 120 accesses the web server 130 for the image 2, requests the corresponding image 2 from the URL address of the image 2 (S280), and receives the reply (S290).

If there are many images, this process is repeated until all of the corresponding image data are provided.

The swap gateway 120 performs a packet reset process on the HTML documents classified as described above (S300).

This packet reset process is a method of arranging data classified as text at the beginning of the packet and data classified as images at the rear of the packet, and the arrangement of the data is shown in FIG. .

Since the swap gateway 120 transmits the packet-resolved packet to the terminal 100 through the open session in a streaming manner, the swap gateway 120 processes the reply (S310), and the terminal 100 transmits the streamed HTML document through the corresponding function unit. Output

That is, since the terminal 100 receives and outputs a packet-resolved web document for streaming, processing time and load for rendering an image are reduced in a terminal that lacks resources.

After confirming the contents of the HTML web document, the terminal 100 requests the end of the session to the swap gateway 120 (S320), and the swap gateway 120 recovers the session that has been allocated and opens the processing result. The terminal 100 responds with a reply and ends (S330).

According to the present invention having the above configuration, the terminal 100, which lacks a resource, accesses the URL address of each image, does not convert the provided image into binary data, and converts the binary data from the swap gateway 120 to binary data. Since the image is provided, there is an advantage of reducing the load (LOAD) of the terminal 100.

In addition, since the image is converted into binary data is provided as a packet by accessing the URL address from the swap gateway 120, there is an advantage that the image data is provided quickly.

In addition, since the terminal 100 is provided with the HTML document in a streaming manner, there is an advantage in that playback is quick.

Although the present invention has been described as an embodiment as described above, the present invention is not necessarily limited to such an embodiment, and various modifications can be made without departing from the spirit of the present invention. Therefore, one embodiment disclosed in the present invention is not intended to limit the technical spirit of the present invention but to describe, and the scope of the technical spirit of the present invention is not limited by the one embodiment. The scope of protection of the present invention should be construed according to the following claims, and all technical ideas within the scope of equivalents should be construed as falling within the scope of the present invention.

According to the present invention having the above-described configuration, since the terminal lacking operational resources is provided with the binary data from the swap gateway, the image rendering processing time and load are reduced so that the terminal can be stably operated. Use effect

In addition, by parsing the HTML document by the WAP gateway, accessing the URL address of the classified image, the image data is provided, and delivered in a streaming manner, so that the terminal can quickly display the web document.
