Description

A reformatting system and method for wireless internet site

The present invention relates to a system and a method for content repetition of a wireless site, and in particular, to define a meta tag based on XML considering a site construction tag for each wireless protocol, and wirelessly based on the wireless internet or a meta tag The present invention relates to a content referencing system of a wireless site and a method for converting the tag into an appropriate tag according to the browser type of the wireless terminal connected to the site.

Recently, wireless site construction has been active. However, since there are various wireless protocols supported by network operators or terminals, building a wireless site requires a lot of time and cost because each protocol must be constructed to support them. .

In other words, the existing method of building a wireless site can be divided into three types. First, there is a method of separately building each content for each protocol, and second, an existing website is built using an automatic conversion software. There is a method of converting to a wireless site, and the third method is to build a wireless site using software that automatically converts only a desired portion of a semi-automatic pre-built website.

Looking at the problems of the existing wireless site construction method as described above are as follows.

1) When building individual sites for each protocol

The method of building an individual site for each protocol can construct the most suitable site for each protocol, but the disadvantage is that the development period is n times longer. Even though the actual process part is taken in common, it takes n times as much to process the interface, and it is necessary to have an expert for each protocol because it needs to know exactly about each protocol.

In addition, in terms of maintenance, when a change occurs, each site that has been individually constructed has to be modified separately, so it takes more time and money, and there is a disadvantage that 100% of the unification of the modification cannot be guaranteed. .

2) When using automatic conversion software

Existing websites and wireless sites could not convert 100% of the screen size and the amount of content, images and sound. In addition, in recent years, websites using flash and the like are continuously increasing, and this also serves as one of the factors that cannot be automatically converted.

This method has the advantage of not having to build a wireless site separately, but it has a big disadvantage in that it is not possible to build a site as desired and that a website must be built.

3) When using semi-automatic conversion software

Semi-automatic conversion is a method of constructing a wireless site by extracting only the desired part from an existing website. However, since there is a clear difference between wired and wireless in terms of content content, sites that are inferior in quality in terms of screen display are inevitably present, and sites built by flash and the like cannot be converted. The disadvantage is that it must be.

In order to solve the above problems, the present invention defines an XML-based meta tag considering a site construction tag for each wireless protocol, and based on this, a browser of a terminal accessing a wireless site made of wireless internet or a meta tag. It is an object of the present invention to provide a content referencing system and method for a content site of a wireless site that converts and transmits an appropriate tag according to a type.

In addition, after performing a step of checking whether or not the grammar of the meta tag according to the DTD document is correct, the method further includes the step of sending an error message if it is written in the wrong format and skipping to the conversion process if it is written correctly.

Referring to the accompanying drawings with respect to the operation of the present invention made of a configuration as described above are as follows.

First, prior to explaining the present method in order to help the understanding of the process of the content referencing method according to the present invention, the function of each component of the content referencing system 16 according to FIG. 1 will be described.

The system 16 is mainly installed in an Internet server, and the message receiving unit 10 located at the front end of the system receives a message for the first time from a wireless terminal such as a cellular phone or PCS.

In this case, the message includes information on which web page the wireless terminal calls, information on a browser mounted on the terminal, and arguments sent to the web page, for example, a query string and a form parameter.

For reference, Query String is a method of passing arguments between pages by adding '?' After the page name. For example, http://www.where.com/list.htm?page=1&user=anybody In the section, the page after '?' And user are the argument names, and 1 and anyboby are the values of each argument. As shown in the example, if there are multiple arguments, separate each argument with the symbol '&'.

Also, Form Parameter is another way to pass arguments between pages on the web. It uses form element, which is usually entered by the user, such as in the text field or by selecting one of several options. It provides a means for input and is a way to pass this value as an argument.

And when passing argument in Form, it is passed by GET or POST method. Query String described above is a kind of GET method. The POST method is commonly used to pass large arguments.

In addition, due to the nature of the Http protocol, header information delivered with a message includes information indicating the language type supported by the terminal, such as the browser name or the Mime type supported by the browser. Through this, the language supported by the terminal is checked and stored.

Currently, the wireless Internet language can be classified into four types, WML, HDML, mHTML, and sHTML, and the header part of the Http protocol indicates which language the terminal supports.

For reference, like the protocol used to send and receive data on the web, the wireless Internet uses these protocols. The data transmitted is divided into a header part and a body part, and the header part includes a data type (Mime) or a browser. It includes the type, IP address of the user, etc. The body part contains the actual data part.

Next, the external process communication unit 12 plays a role of exchanging information with the external processor 11, which is a practical module for generating content in the wireless Internet.

That is, it determines which page of the messages transmitted to the message receiving unit 10 is called, calls the corresponding external processor 11, and receives the result of the called external processor 11 again.

For reference, the external processor 11 may be regarded as a program that actually configures content. The external processor 11 is configured in the form of a common gateway interface (CGI) used in the existing web.

In other words, after performing business processes such as database access and returning the result to the HTML language according to the screen configuration, the external processor 11, which is referred to here, does not output the HTML for the predefined remapping. The only difference is that they are organized by language.

In addition, the external processor 11 may perform a function of collecting specific data from a database according to the nature of the web page, or may simply pass information previously prepared.

At this time, if a factor is included in the message received from the message receiving unit 10, this factor is also passed to the external processor 11 as well. In addition, the external processor 11 performs a unique task, and configures the result according to a predefined referencing language, and then passes the result back to the external process communication unit 12.

Next, the message checker 13 verifies whether the information provided from the external processor 11 is configured and delivered according to a predefined language.

That is, the content delivered from the external processor 11 goes through a process of confirming that the content is correctly configured before being converted by the referrer 14 through the external process communication unit 12. This is done by examining whether the content conforms to the defined DTD according to the defined DTD.

If the content is improperly configured, an error message can be immediately output without going through the conversion process.

Next, the referrer 14 converts a content composed of a meta tag, which is a predefined language, into a language supported by the terminal.

That is, upon receiving the content configured in the predefined language, the target language is set according to the supported languages of the previously examined wireless terminals, and the content is converted according to the target language through a predefined style sheet for each language.

The stylesheet is defined for the XSLT format, which is a subset of XML.

That is, the style sheet may be referred to as a document defining what types of tags will be finally converted to meta tags defined according to XML.

Finally, the message transmitter 15 transmits the received content to the wireless terminal. That is, the content received from the ripper meting unit 14 is finally delivered to the wireless terminal requested through the message transmitter 15.

An example of a content referencing method implemented through a content referencing system having configurations having such a function will be described with reference to the flowchart of FIG. 2.

When a wireless Internet user looks up new announcements from a community that is subscribed to a community site search, he requests to display the second page of the announcement through the wireless terminal.

The message receiving unit 10 located at the front end of the referrer system 16 receiving the request signal determines which language the terminal used by the user supports. To this end, a message sent by a browser mounted on the wireless terminal It is necessary to extract the browser type and MIME type from the information contained in the header by analyzing the.

For example, if the information extracted from the header is 011 user, the wireless terminal is supported by WML, and if the user is 017, 019, the terminal is supported by HDML. If the user is 016 and 018, the terminal is supported by mHTML. Is supported.

As described above, when the user requests the second page of the announcement, the message receiving unit 10 receives the message and determines the terminal protocol type as described above, and then sends a predetermined signal to the external process communication unit 12 again. The processor communication unit 12 sends a predetermined signal to the external processor 11 to call the requested information.

That is, the external processor communication unit 12 sends the requested second page argument to the external processor 11 and is thus provided with a list of announcements among the processes previously prepared from the external processor 11.

Looking at this process in more detail, once called, the external processor 11 gets a list of the titles of the announcements from the database (not shown in the figure). The 11th through 20th lists are retrieved, arranged according to the predefined screen specifications, and the document is created in the predefined Meta Tag format and passed the result value.

On the other hand, the document created in the meta tag format as described above is examined whether the message check unit 13 correctly written according to the grammar of the meta tag according to the DTD document predefined for the format of the meta tag. If it is written as an error message is immediately shown, and if written correctly, the written document is transferred to the following repermitting unit 14.

In addition, before performing the conversion process in the referrer 14, after checking the target protocol of the wireless terminal and loading the corresponding style sheet according to the definition of the identified target protocol, the language used in the wireless terminal is If WML is used to load WML stylesheets, if the language used is HDML, it will load HDML stylesheets. If the language used is mHTML, it will load mHTML stylesheets. If the language used is sHTML, it will load sHTML stylesheets.

Subsequently, the referrer 14 converts the content defined by the XML-based meta tag received from the message checker 13 according to the target protocol based on the style sheet loaded in the previous step.

Through this step, the result of the content corresponding to the language that can be identified by the browser of the wireless terminal is obtained as a result, and the finally obtained content is re-transmitted to the wireless terminal which originally requested. Thus, the user can view the second list of announcements, the desired information, with his wireless terminal.

Meanwhile, in the referencing method as described above, a process of converting a message composed of a predefined XML-based meta tag to a current Internet language may be added to be received by any wireless terminal.

To this end, as shown in FIG. 3, the referrer 24 additionally configures a part for converting an input message into an XML-based meta tag (hereinafter, referred to as 'MML') and a part for converting an MML into a target output message. Just do it.

The function of the added part will be described in detail with the process of FIG. 4 as follows.

The external processor 21, which receives the argument from the external process communication unit 22, goes through an internal process such as DB access and statistical calculation, and outputs the result content in one of the Internet languages such as WML, HDML, mHTML, and sHTML. Pass it back to.

The received content checks whether the message checker 23 follows the grammar of each language based on the DTD for each language defined in advance, and if an error occurs, transmits an error message to the terminal.

Next, we analyze the header of the message to see what language the content is written in. The language supported by the wireless terminal can be known by analyzing the contents of the Http header transmitted from the browser embedded in the terminal. Normally, you can check the contents of the header by the supported content type or browser name.

In other words, after checking whether the content is written according to the protocol through the content type of the header, if it is the same as the protocol supported by the wireless terminal, it is sent to the wireless terminal without going through the conversion process. Going through.

The conversion process can be broadly divided into two processes. First, a process of converting the content transferred from the external processor 21 into an MML form and a process of converting the converted MML content into a form that can be recognized by a wireless terminal.

In other words, in order to replace the content transferred from the external processor 21 to MML, a style sheet for converting the protocol of the content into the MML form is loaded. Next, we load the stylesheet that replaces the MML with the terminal-side content and perform the conversion.

The completed content is retransmitted to the wireless terminal that was originally requested through the message transmitter 25.

As can be seen from the above description, the present invention provides a message receiving unit 20 for receiving a message transmitted from a wireless terminal, checking and storing a language supported by the wireless terminal, and an external processor 21 for providing contents on the wireless Internet. And an external process communication unit for determining which page of the message received by the message receiving unit 20 is called and calling the corresponding external processor 21 and receiving output data performed by the called external processor 21 ( 22) and a message checker 23 for confirming whether the content transmitted from the external processor 21 is configured and transmitted according to a meta tag which is a wireless internet language or a predefined language, and the message checker 23 Referrer unit for converting the content consisting of the wireless Internet language or meta tag identified by the language supported by the terminal (2 4) and a message transmitter 25 for transmitting the content output in the language converted by the referrer 24 to the first requesting wireless terminal.

By installing it on the server side of the wireless Internet, it can convert the content according to the protocol of the wireless terminal that requested various services, and then transmit the contents.In addition to the existing website and the development of a new wireless specialized site, It is useful to greatly reduce system development time and maintenance cost by simply converting to a protocol suitable for each wireless terminal without building a separate site.
