The present invention relates to a method for enabling access to an internet web page using a mobile communication terminal, and more particularly, compresses an internet web page provided from a web server into a picture file in a snapshot form and then converts the web page into a mobile communication terminal. The present invention relates to a method of accessing an internet web page using snapshot navigation that provides web navigation using the coordinate information of a picture file pointed to by a mobile communication terminal.

Recently, due to the development of mobile communication terminals and mobile communication services, the number of users using mobile communication terminals is continuously increasing every year. In addition, the usage of the mobile communication terminal is enjoying a variety of additional services, such as voice communication, data communication and Internet web page navigation using a variety of content to access the Internet.

A general method for displaying a general Internet web page in a mobile communication terminal, as shown in FIG. 1, is displayed by the mobile communication terminal 10 having a WAP browser that provides a function of displaying an Internet web page. The web page to be requested is requested to the WAP Gateway / Proxy 30 through the base station 20 (or directly connected to the web page server in the case of Proxyless HTTP connection), and the WAP Gateway / Proxy 30 is connected to the Internet 40. Access to the site through the web page information is received, and transmits it to the mobile communication terminal 10 through the base station (20). The WAP browser of the mobile communication terminal 10 parses the received web page information and processes it. In this case, if the web page includes an image, the web page information necessary through the base station 20 is described in the above-described manner. Additional request is made to WAP Gateway / Proxy, and the final web page is composed and shown using the image information received through the response.

However, WAP browsers that have the ability to display Internet web pages, when parsing web pages received through (or directly) through a WAP Gateway / Proxy, have the functionality of a web browser for personal computers (PCs) in addition to the basic HTML tags, There are some cases that deal with tags that do not adhere to HTML syntax that is common in web sites, content that is difficult to process in general WAP browser, etc. In this case, WAP browser generally ignores unprocessable tags or uses error response routines. Only those that can be processed by the WAP browser are marked on the mobile communication terminal.

Because most web contents provided on the Internet are made in consideration of being displayed on the screen of a computer by using a PC web browser, the general mobile communication terminal in all aspects such as the size, type, and required processing power of the contents are required. There was a limit to marking.

In order to overcome these limitations, efforts have been made to improve the function of the WAP browser of the mobile terminal, but it is not possible to display it using the WAP browser of the mobile terminal in a situation where the number of sites requiring new technologies and new plug-ins is constantly increasing. There were many difficulties to solve. These problems were a problem for both the mobile operator and the users of the mobile terminal.

The present invention has been made in view of the conventional technology described above, and an object of the present invention is to specify a mobile communication terminal that has a relatively low processing function and does not support a web browsing function as in the format used in a conventional PC. The purpose is to show the web page of the site.

It is another object of the present invention to perform web navigation in a mobile communication terminal, and there is a difference in parsing and content display capability caused by using a WAP browser having different characteristics and capabilities, and a corresponding routine for a situation in which an exceptional event occurs. It is to solve the disadvantages that appear.

Another object of the present invention is to facilitate the updating, maintenance and repair of the process because the configuration of the web navigation screen to be displayed to the user of the mobile communication terminal in the snapshot web gateway managed by the mobile carrier. .

In order to achieve the above object, the method for accessing an internet webpage using snapshot navigation according to the present invention is connected to a web server on which the specific webpage is driven when the access request for a specific webpage is received from a mobile communication terminal. A first step of receiving contents of a specific web page; A second step of making the contents of the provided web page into a snapshot file; And a third step of transmitting the picture file to the mobile communication terminal.

Hereinafter, with reference to the accompanying drawings will be described an embodiment according to the Internet web page snapshot navigation control procedure in the mobile communication terminal of the present invention in detail.

2 is an explanatory diagram for explaining a web page snapshot navigation operation in a mobile communication terminal according to the present invention.

Referring to FIG. 2, the snapshot web browser provided in the mobile communication terminal 110 is an additional function of a function module or a WAP browser in the mobile communication terminal, and is a snapshot web gateway. In conjunction with 130, the user provides Snapshot Web Navigation.

In addition, the Snapshot Web Gateway 130 is a function process of an additional function or an independent device of the WAP gateway, and is snapped to the user by the mobile terminal by interworking with the snapshot web browser provided in the mobile terminal. Enable shot web navigation.

Here, the screen configuration of the snapshot web browser operates in a zoom out mode and a zoom out mode as shown in FIGS. 3A to 3D. For each mode, the user can enter a key of the mobile communication terminal. You can set the number of dots to move when you press the up, down, left, or right keys provided on the operation panel. According to an embodiment of the present invention, when the user of the mobile communication terminal further moves the keys up, down, left, and right from the top, bottom, left and right ends of the current LCD display screen, the screen of the mobile communication terminal shows the scrolled screen in the corresponding direction. Lose.

When the LCD display screen of the mobile communication terminal enters the reduced mode in the enlarged mode illustrated in FIG. 3D, the LCD display screen of the mobile communication terminal enters the reduced mode in which the area of the selected screen is drawn 1: 1. The reduced mode is a mode for showing the overall screen configuration of a web page and reducing the burden on screen scrolling due to the characteristics of a mobile communication terminal and allowing a user to quickly move to a desired area. In this case, the user may determine the enlargement multiple of X2, X3, X4, etc. according to the size or preference of the LCD of the mobile communication terminal.

The reduced mode is a mode in which a web page is drawn 1: 1 on an LCD display screen of a mobile communication terminal. In this mode, a user clicks a link of an exact position of a desired item as shown in FIG. 3A, or shown in FIG. 3B. As can be done, it is possible to click on an edit item.

In addition, the user can set the snapshot angle function, as shown in Figure 3c, which does not receive the full screen of the web page of the specific URL from the mobile communication terminal in order to save data communication costs, the specific portion of interest Used to request to send only

When the mobile terminal user uses this snapshot angle function on a specific screen and designates the rectangular area of the LCD display screen of the mobile terminal by specifying the up, left, down, and right points in the reduction or enlargement mode, the snapshot The web browser stores the exact URL of this screen, but the next time this web page is opened, the next time this web page is opened, it sends the request information to the snapshot web gateway 130 and sends the region information to the snapshot angle data in the request packet. Send and notify, and the snapshot web gateway 130 may reduce the snap. The function described above can be freely set and released according to the intention of the user of the mobile communication terminal.

In addition, the core function of the snapshot web gateway 130 shown in FIG. 2 is equipped with a browsing function of a general PC, processing of tag parsing, script processing, plug-in, etc. contained in a real web page, and as a result Actually, the screen to be displayed on the PC browser screen is made into a compressed picture file such as JPEG and transmitted to the mobile terminal.

In addition, after receiving the pointing input from the user, the browser is floating on the snapshot web gateway, and when the link is clicked as if the corresponding coordinate is clicked, the link is received and the snapshot is made and transmitted to the mobile communication terminal again. Receiving the result at the edit position, it is as if the browser is floating on the snapshot web gateway 130, and receives the result screen as if the input to the edit item to take a snapshot and transmit it to the mobile communication terminal.

In this manner, the snapshot web gateway 130 acts as a medium for web navigation that receives and processes the user's input from the mobile communication terminal while actually operating a browser in the middle of the user's mobile communication terminal and the corresponding website.

In addition, in addition to the basic operations described above, the snapshot web gateway 130 receives and applies a cookie stored in the mobile communication terminal of the user, and applies the set snapshot to the snapshot web gateway 130. ) Requests the user's mobile communication terminal to store the cookie data of the content.

In addition, the snapshot web gateway 130 receives the snapshot angle information, creates a snapshot data of a region and size desired by the user for the corresponding page, and performs an operation in accordance with other user's snapshot settings.

5 is a flowchart illustrating a procedure in which an Internet web page is displayed in a mobile communication terminal using snapshot navigation according to the present invention.

When the user of the mobile communication terminal wants to execute the web navigation function, the user of the mobile communication terminal drives a snapshot web browser provided in the key input unit of the mobile communication terminal (S101).

Subsequently, the user can allow pop-ups through the setting menu of the mobile communication terminal, whether to receive additional data in the scrolled area (eg, Naver or Yahoo newsbox), whether to send additional content types, or save / delete cookies. A web navigation condition such as whether or not is set (S102), and a snapshot web gateway 130 is requested through the base station 20 to open a web page of a specific URL through selection of a bookmark menu or input of a URL (S103).

At this time, the mobile communication terminal determines whether the user has set the snapshot angle function to the URL. As a result, when the snapshot angle function is set, the snapshot angle information is inserted into the data field of the open request message and transmitted to the snapshot web gateway 130.

Also, it is determined whether cookies are used among setting information of the snapshot web browser. As a result of the determination, when the use of cookies is set, the list of cookies currently stored in the mobile communication terminal is inserted into the data field of the open request message and transmitted to the web gateway 130.

In addition, the user determines whether there is a setting different from the default value defined in the snapshot web gateway 130 among the setting information of the snapshot web browser. If it is determined that there is a setting different from the default value, the details are also inserted into the data field of the open request message and transmitted to the snapshot web gateway 130.

4 shows a block diagram of the data frame of the open request packet generated by this process, and the packet is delivered to the snapshot web gateway 130 through a specific port number.

At this time, the snapshot web gateway 130 receives the URL open request message and allocates one process to manage the connection session (S104).

Subsequently, the process allocated by the snapshot web gateway 130 interprets the request of the opening request message, so that the setting condition information, the cookie list information, and the corresponding URL snapshot angle information of the snapshot web browser of the mobile communication terminal are shown in FIG. 4. It is determined whether it is included in the field of the data frame shown in (S105). As a result of the determination in step S105, when there is the setting condition information, the cookie list information, and the snapshot angle information, the process stores this as local data in the memory (S106).

Then, the process opens an HTTP session of the requested web page URL and transmits an open request message (Open Request) to the web server 150 via the Internet 140 (S107).

The process then searches the cookie list to determine if there are any cookies with domains and paths that match the requested URL. As a result of the determination, if there is cookie information, the cookie data is requested to the mobile communication terminal. The mobile terminal transmits the requested cookie data to the process, and the process stores the received cookie data in a local cookie cache and inserts it in a cookie header to transmit it to the web server 150.

Subsequently, the web server 150 transmits the web page requested by the processor of the snapshot web gateway 130 and the contents thereof to the processor of the snapshot web gateway 130 (S108).

The process of the snapshot web gateway 130 parses and renders the received contents (S109), and determines whether the snapshot angle function is set in the corresponding URL by referring to the setting conditions of the snapshot web browser (S110). ).

If it is determined in step S110 that the snapshot angle function is set, the process of the snapshot web gateway 130 reconstructs the screen of the web page according to the snapshot angle (S111), which is a compressed picture such as a JPEG of 1: 1 scale. Create a file (S112).

Subsequently, the process of the snapshot web gateway 130 allocates a unique page identifier (ID) to the compressed picture file and transmits it to the mobile communication terminal (S113).

The mobile communication terminal receives the picture file transmitted from the snapshot web gateway 130, and displays the received picture file in the enlarged mode of the multiple set by the user on the LCD display window (S114).

At this time, the displayed picture file shows the area to be displayed when the user enters the reduced mode, so that each time the user clicks by using the left and right arrow keys or other pointing device, the set dot can be moved.

For example, when the user moves the direction key of the mobile terminal and clicks to select the reduction mode, the process displays a 1: 1 scale picture corresponding to the corresponding position.

In addition, the user can click the control button by using the direction keys of the front and rear, left and right or by moving the pointer to click a link, edit, or other control button (for example, a radio button, a check button, a push button, and the like).

The mobile communication terminal calculates the position in the 1: 1 mode by summing the dots moved in the zoomed-out mode and the zoomed-out mode in the zoomed-out mode, making them pointing information, together with the page ID, to the snapshot web gateway 130. send.

When the process of the snapshot web gateway 130 receives the pointing information, it determines whether the page identifier and the page that was just taken by the snapshot and transmitted before are the same. As a result, if it is determined that the page and the page identifier are not the same, it is determined whether the previously transmitted page and the page identifier are the same.

As a result of the determination, if it is determined that the page and the identifier of the page previously transmitted, the process of the snapshot Web gateway displays a screen as if the user clicked the corresponding position of the page in the Internet browser.

However, since the interaction with the user actually occurs in the mobile communication terminal, for example, when the user clicks the editor, the user must receive the user input from the mobile communication terminal. The user should receive the user's input at the mobile communication terminal by sending a request. (In this case, if there is format information of the editing, the process is included in the field promised in the edit input request message and transmitted to the mobile communication terminal.)

For example, when receiving an edit input request message from the user, the snapshot web browser of the mobile communication terminal displays an edit corresponding to the edit format information and displays an edit input response message asking whether the user inputs the input. To the snapshot web gateway 130. The snapshot web gateway 130 receives the edit input response message, and operates as if the edit item is input in the Internet browser.

In this case, when only the screen is updated, the process updates the screen to send a screen update request message (Screen Update Request) to the mobile communication terminal together with the coordinates of the uppermost left end point and the size of the changed area. After updating only the corresponding part of the page, the mobile communication terminal sends a screen update request message to the snapshot web gateway 130.

In addition, when moving to a new page due to editor input, a new page identifier and a snapshot are created and transmitted to the mobile communication terminal in the same order as the new URL is requested.

At this time, if the link is clicked, it operates to fetch the hyperlinked URL page as described above, and even if the user clicks a control other than editing, the screen is only updated or moved to a new page. It works as described.

If the user clicks on a place where there is no content, it is preferable to send a pop-up in the snapshot web browser to inform the mobile communication terminal that the empty space is clicked. In this way, the user may be able to distinguish the case where the pointing information is lost in the wireless section.

This will enable basic web browsing. Of course, the actual Internet web pages are implemented with various contents such as CGI, various scripting languages, Flash, etc., but in each case, as in the above methods, parsing is performed at the snapshot web gateway 130 by user input. Can be implemented in an appropriate manner by the same principle as in the snapshot web browser of the mobile communication terminal.

Commonly regarded as a snapshot of a web page, Naver, etc. Newsbox (first, first, second, third, and last article links, depending on the time, and later, links to articles 4, 5, 6, etc.) Is implemented by showing only the link to the article at the time the snapshot was taken.

When parsing a document, if there is a newsbox, it takes the main snapshot as a whole webpage, assigns a page identifier, and randomly arranges the article links (or photo links) in the newsbox on a blank webpage. You also create a page to take a snapshot of this page and assign it a page identifier.

In addition, the main page and the subordinate page become respective page items to form and transmit an opening response message which is a response to the opening request message. At this point, the snapshot web browser can distinguish between the main page and the dependent page by looking at the content type field value, and knows which subordinate page will be displayed when the user clicks the main page in the page area field of the dependent page item. Can be.

In addition, the snapshot web browser that receives the data shows the main page to the user, and when the user clicks on the main page, the snapshot web browser does not necessarily make the pointing information and transmit it to the snapshot web gateway 130. Then, it is determined whether the clicked point belongs to the subordinate region. As a result of the determination, when belonging to the dependent region, only the dependent page is opened and displayed to the user.

In addition, since the snapshot web gateway 130 transmits the identifier and the click information of the dependent page when a specific location is clicked in the dependent page, the snapshot web gateway 130 subordinates the click to the page identifier. You can see that it happened within the page.

In addition to the above implementation method, the first transmission only transfers the main page, and when the subordinate area is clicked, the snapshot web browser transmits only the click information to determine whether the received snapshot web gateway 130 is the newsbox area. It can also be implemented by sending a subordinate page, or by setting it as a setting, it can also be implemented to operate in the way the user wants.

The snapshot web gateway 130 has an idle timer in addition to receiving and ending an end notification message sent by the snapshot web browser in preparation for a sudden battery detachment / out of coverage of the user. For example, if there is no action for a certain period of time, it is desirable to have a mechanism for terminating the process.

At the end of this process, all data related to the session of a specific user that was created during the process is also erased, so that even if a long time is used by many users, system resources are not exhausted.

In the mobile communication terminal according to the embodiment of the present invention described above, the method for controlling the Internet web page snapshot navigation provides the following operational efficiency.

Considering the performance of scrolling and displaying compressed pictures in snapshot web browsers, many mobile communication terminals are equipped with cameras, and the decoding, display and scrolling of compressed picture files such as JPEG can be performed by DSP or separate This is often done by the processor. In this case, there is no problem in speed because the display and scrolling as well as the decoding speed are directly accessed in a very fast way.

Even if the snapshot web gateway does not have a separate processor, most mobile terminal JAVA implementations use a method of directly accessing and displaying the LCD buffer. none.

In addition, even in the zoom mode used in the embodiment of the present invention, since only a fixed multiple zoom mode such as X2 and X3 is used, the image codec algorithm may be better characterized by such characteristics. You can get it.

Looking at the efficiency of traffic volume and intercommunication (transaction) traffic to and from the network, when Naver homepage was saved as page storage in Internet Explorer, it was about 50 files, totaling 160 ~ 170KB. When the web page is encoded and saved in true color JPEG to take a snapshot, it uses basic baseline encoding and has a size of about 230KB at low level and about 280KB at medium level. It is made into an image.

As such, when the image is received instead of the actual content, the size to be transmitted is slightly increased, but this can be further reduced by appropriately applying the number of colors, encoding methods, and image formats. While about 50 transactions are performed in the wireless and wired sections to come, only 50 transactions occur when the content is transmitted as a picture. Therefore, the overhead of packet headers other than the content is considered, and the snapshot angle function is used. Considering that you do not receive additional content (flashes, videos, etc.) on the page, the increase in the transmission amount in the radio section does not really matter.

And, given the reduced number of transactions and the time spent parsing and rendering web pages in WAP browsers, even if some WAP browsers support HTTP pipelining, the amount of time that a snapshot web navigation that does not support them actually waits. May be less.

However, since a transaction needs to receive a large amount of snapshot data as a single transaction, it is fatal to packet loss that can occur in a wireless section. Therefore, in the present invention, communication between the snapshot web browser and the snapshot web gateway supports TCP that supports selective acknowledgment. It is preferable to build using.

As described above, according to the method for controlling Internet web page snapshot navigation in the mobile communication terminal according to the present invention, the following effects are provided.

First, it has a relatively low processing function and can greatly enhance user's service convenience because it can show the web page screen of a specific site to the mobile communication terminal which does not support web browsing function as the format used in the existing PC. You can.

Second, the disadvantages of web navigation in mobile communication terminals are due to differences in parsing and content display capabilities caused by using WAP browsers with different characteristics and performances, and in response to specific exception events. I can get rid of them. Therefore, the mobile communication service provider can reduce the effort to establish standards, reduce the implementation effort of the manufacturer, it is possible to provide a consistent service of the same screen to all users.

Third, since the web navigation screen configuration to be displayed to the user of the mobile communication terminal is performed by the snapshot web gateway managed by the mobile communication service provider, the process can be easily updated, maintained, and repaired. The present invention is not limited to only one embodiment and can be modified and modified without departing from the scope of the present invention, and such modifications and changes should be regarded as belonging to the following claims.
