If necessary, the application content can be received through the content relay conversion server.

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

Web content transmission and reception system according to an embodiment of the present invention, as shown in Figure 1 mobile terminal 100, base station 510, mobile communication network 520, content relay conversion server 300, the Internet network 540 ), The content providing server 200 is configured.

Here, the content providing server 200 provides a markup page and application content. A markup page refers to a text page written in a markup language, and a markup language refers to a document using predetermined markup tags such as HyperText Markup Language (HTML), eXtensible Markup Language (XML), and Wireless Markup Language (WML). Anything that represents the content and structure of a is included.

The content providing server 200 may be configured as a kind of web server. The content providing server 200 provides previously stored markup pages or application contents in response to a request from the mobile communication terminal 100 or the content relay conversion server 300 as described below. .

Here, the application content is content processed in a specific application driven in the mobile communication terminal 100. For example, when the application driven in the mobile communication terminal 100 is a pdf document viewer program, the application content is stored in a pdf format document. This may be the case.

The content relay conversion server 300 relays transmission of application content between the content providing server 200 and the mobile communication terminal 100 and converts various types of application content into one single format.

That is, the content relay conversion server 300 converts various types of application content received from the content providing server 200 into a single predetermined format and then transmits the converted content to the mobile communication terminal 100.

The mobile communication terminal 100 may include various types of contents of the content providing server 200 even though the mobile terminal 100 includes only the content processing module 122 capable of processing contents of a specific format without having to support various types of formats. This is for processing in 100).

For example, only the pdf document viewer program is installed in the mobile communication terminal 100. The content relay conversion server 300 converts all documents of various formats received from the content providing server 200 into a pdf format, thereby converting the documents into a pdf format. If delivered to (100), the mobile communication terminal 100 processes all types of documents provided by the content providing server 200 regardless of the format (since it has already been converted to pdf format) to the user of the mobile communication terminal 100 Allows you to view the document.

The mobile communication terminal 100 is a wireless communication terminal device including a mobile phone, personal digital assistants (PDAs), and the like. The mobile communication terminal 100 receives a markup page from the content providing server 200 through the mobile communication network 520 as well as a voice call with the other party. It may be received and displayed on the display unit 150.

In addition, the mobile communication terminal 100 extracts the address of the hyperlink selected by the user from the markup page displayed on the display unit 150 and displays the corresponding hyperlink based on the file extension included in the extracted hyperlink address. If it is determined that the hyperlink corresponding to the preset application content, the content relay conversion server 300 requests the transmission of the application content.

For example, when the hyperlink selected by the user of the mobile communication terminal 100 is <a href=http://aaa.bbb/test.pdf>, the mobile communication terminal 100 is an address of the hyperlink, that is, Extracts "http: //aaa.bbb/test.pdf" and determines whether the corresponding hyperlink corresponds to the preset application content based on the file extension "pdf" from the extracted address, that is, the URL (Uniform Resource Locator). do.

For example, the mobile communication terminal 100 has a file extension of 'pdf', 'doc', 'hwp', 'xls', 'ppt', 'dot', 'gul', or 'txt'. It is determined that the content is the content of the document format. In this case, the content of the document format corresponds to the application content.

That is, the mobile communication terminal 100 may determine that only the content of the document format is the application content, or may determine all kinds of contents other than the markup page such as html, for example, video, image content, etc., as the application content. . Whether the content corresponds to the application content may be determined based on setting information preset in the mobile communication terminal 100.

As described above, the mobile communication terminal 100 communicates with the content providing server 200 and the content relay conversion server 300. The content providing server 200 communicates with the base station 510, the mobile communication network 520, and the router 530. Communication through the Internet network 540 and the content relay conversion server 300 through the base station 510 and the mobile communication network 520, and the communication through the base station 510 and the mobile communication network 520. And, since the communication process to the Internet network 540 is only a known technique, a detailed description thereof will be omitted.

In the present embodiment, the content relay conversion server 300 is provided as a mobile communication network 520 as an example, but the content relay conversion server 300 may be provided in the Internet network 540 together with the content providing server 200. Of course.

2 schematically illustrates a communication flow between the mobile communication terminal 100, the content providing server 200, and the content relay conversion server 300.

As shown in the figure, the mobile communication terminal 100 receives the markup page directly from the content providing server 200, and the content relay conversion server 300 for the application content included in the markup page in the form of a hyperlink. Receive through.

In order to explain specific functions of the mobile communication terminal 100, a functional block of the mobile communication terminal 100 is illustrated in FIG. 3.

As shown in the figure, the mobile communication terminal 100 includes a communication interface 110, a storage 130, a controller 120, a key input 140, and a display 150.

The communication interface unit 110 is a component that enables wireless communication through the base station 510. The communication interface unit 110 transmits a signal generated by the control unit 120 to the base station 510 and receives a predetermined signal from the base station 510. To perform the function of transmitting to the control unit 120.

The storage unit 130 is a place where predetermined setting information or temporary data is stored, and may be configured as a flash memory to prevent setting information from being erased even when the power is turned off. In particular, the storage unit 130 stores a file extension list. The file extension list corresponds to a set of file extensions corresponding to the application content.

The display unit 150 is a place where a predetermined image is displayed and may include a liquid crystal display (LCD) with low power consumption.

The key input unit 140 is a user interface for a user to view a screen displayed on the display unit 150 and make a menu selection or predetermined data setting. The key input unit 140 may include at least one key button.

The controller 120 includes a markup page processing module 121 and a content processing module 122.

The markup page processing module 121 parses and renders the markup page received from the content providing server 200 and displays the markup page on the display unit 150, and displays the markup page on the display unit 150 to the user. Extracts the address of the hyperlink selected by the processor, and determines that the hyperlink is a hyperlink corresponding to the application content, based on the file extension included in the extracted hyperlink address, the content processing module 122 for processing the application content; Drive it.

That is, the markup page processing module 121 determines that the hyperlink corresponds to the application content when the file extension included in the extracted hyperlink address is the extension included in the file extension list stored in the storage unit. It drives the content processing module 122 for processing the application content.

After the content processing module 122 is operated by the markup page processing module 121 as described above, the content processing module 122 transmits to the content relay conversion server 300 based on the hyperlink address received from the markup page processing module 121. The application content is transmitted, the application content received from the content relay conversion server 300 is processed, and the content of the corresponding application content is displayed on the display unit 150.

For example, if the address of the hyperlink selected by the user on the markup page received from the content providing server 200 is "http: //aaa.bbb/test.pdf", the markup page processing module 121 Determines that the hyperlink selected by the user corresponds to the application content in the document format, and executes the application content processing module 122-for example, a pdf document viewer-and executes the address of the hyperlink. To pass). In this case, the markup page processing module 121 may transmit pre-stored login session information to the content processing module 122 through communication with the content providing server 200.

Here, the login session information is authentication related information transmitted from the content providing server 200 while the mobile terminal 100 logs in to the content providing server 200, and the content providing server 200 receives a predetermined content request. If so, it is determined whether the content request is a request from a terminal having a legitimate authority by checking the login session information.

As such, the login session information is information necessary for authentication processing in the transmission and reception of predetermined content after the login process is performed, and when the predetermined content is requested to the content providing server 200, the login session information must be transmitted together.

The login session information will be described in more detail as shown in FIGS. 4A to 4C.

First, FIG. 4A illustrates an example of data transmitted when a user inputs a user ID and password to log in at www.kipo.go.kr. That is, such data may be transmitted from the mobile communication terminal 100 to the JPO web site server. In this embodiment, the case of using the HyperText Transfer Protocol (HTTP) is taken as an example.

4B illustrates an example of data transmitted from the JPO Web site server to the mobile communication terminal 100 according to the login transmission as shown in FIG. 4A.

As shown in the figure, the JPO web site includes cookie information, that is, login session information, in the cookie setting header 153 after the login process, and transmits the cookie information to the mobile communication terminal 100. As described above, the login session information transmitted to the mobile communication terminal 100 is included in the cookie header 154 when the KIPO web site is accessed as shown in FIG. 4C, and thus the KIPO web site is logged in based on the cookie or session information. Perform the authentication process.

That is, according to whether there is login session information from the mobile communication terminal 100, the JPO site server determines whether to provide content requested from the mobile communication terminal 100.

As such, the login session information is information necessary to maintain a connection with the content providing server 200 providing markup data and content such as a web site on the Internet.

Meanwhile, the driven application content processing module 122, that is, the pdf document viewer, requests the content relay conversion server 300 to transmit the application content.

At this time, the pdf document viewer transmits the application content address and the login session information received from the markup page processing module 121 to the content relay conversion server 300.

The pdf document viewer interprets the pdf format file received from the content relay conversion server 300 and displays the file in the display unit 150. At this time, even if the application content requested by the pdf document viewer to the content relay conversion server 300 is not a pdf format but is, for example, a PowerPoint format, that is, a format having an extension of 'ppt', the content relay conversion server 300 Since the contents of the ppt format are converted into the pdf format and transmitted, the pdf document viewer can always receive the application contents of the pdf format from the content relay conversion server 300.

Meanwhile, when determining that the hyperlink selected by the user is not a preset application content, the markup page processing module 121 requests the content providing server 200 to directly transmit the content.

At this time, by analyzing the header of the content received from the content providing server 200, if the MIME (Multipurpose Internet Mail Extensions) type of the header includes information that the content corresponds to the application content, markup page processing The module 121 stops communication with the content providing server 200 while driving the content processing module 122 and delivering the address of the application content and the login session information to the content processing module 122 as described above to process the content. The operation of the module 122 allows the corresponding application content to be received.

Hereinafter, a control process of a web content transmission and reception system according to an embodiment of the present invention will be described in detail with reference to FIG. 5.

First, when the markup page processing module 121 of the mobile communication terminal 100 detects a markup page request command according to the user's key input unit 140 (step S1), the markup page processing module 121 marks up the content providing server 200. The page request signal is transmitted (step S3).

The content providing server 200 extracts and sends the requested markup page from the mobile communication terminal 100 (step S5).

The markup page processing module 121 receiving the markup page from the content providing server 200 parses and renders the received markup page (step S7) and displays it on the display unit 150 (step S9).

Subsequently, the login session information is transmitted and received along with the login process between the markup page processing module 121 and the content providing server 200 according to the user's ID and password input (step S11). Since the process of inputting information (ID and password) is a well-known technique, a detailed description thereof will be omitted.

After the login is made, the markup page processing module 121 stores the login session information received from the content providing server 200 (step S13).

In this state, if the hyperlink selection on the markup page is detected by the user (step S15), the markup page processing module 121 extracts the selected hyperlink address (step S17) and the file extension of the extracted address is preset. It is determined whether the extension corresponds to the application content (step S19).

For example, when the user selects a hyperlink 151 representing an attachment on a webmail screen as shown in FIG. 6A, the markup page processing module 121 includes a file including an address of a hyperlink selected by the user. Extract the extension of. In the example of FIG. 6A, the extension of the extracted file corresponds to pdf.

If extensions such as pdf, doc, hwp, xls, ppt, dot, gul, and txt have been previously set as the extension corresponding to the application content, the markup page processing module 121 displays the hyperlink address and the login session information as the content processing module. Transfer to step 122 (step S29). In this case, the markup page processing module 121 may first control the content processing module 122 to process the application content to be driven.

The driven content processing module 122 requests the application content from the content relay conversion server 300, and transmits the hyperlink address and the login session information together (step S31).

The content relay conversion server 300 transmits the login session information to the content providing server 200 and requests the transmission of the application content (step S33), and the content providing server 200 receives the login session information received from the content relay conversion servo. The login session authentication process is performed based on the step S35.

That is, it is determined whether there is an application content request authority based on the received login session information.

If the login session authentication is made (step S35), the content providing server 200 transmits the requested application content to the content relay conversion server 300 (step S37), and the content relay conversion server 300 is the content providing server ( The application content received from 200 is converted into application content of a single format (step S39).

That is, when the single format is previously set to the pdf format, the content relay conversion server 300 is configured to download all the application content of various formats having an extension of doc, ppt, hwp, xls, etc. received from the content providing server 200 in pdf format. To.

In this embodiment, since the application content requested by the mobile communication terminal 100 corresponds to a pdf file, a separate content conversion process may not be necessary.

The content processing module 122, which has received the application content from the content relay conversion server 300 (step S41), processes the corresponding application content and displays it on the display unit 150 so that the user can view the corresponding content ( Step S43).

An example in which the application content is displayed on the display unit 150 is illustrated in FIG. 6B.

Hereinafter, a control flow of a web content transmission / reception system according to another embodiment of the present invention will be described with reference to FIG. 7.

In the description of this embodiment, a description of a process overlapping with the embodiment described above with reference to FIG. 5 may be omitted. In particular, in FIG. 7, steps S1 to S7 of FIG. 5 are omitted for convenience of description.

The process from step 9 'displaying the markup page to step S17' extracting the hyperlink address selected by the user corresponds to the process from step 9 to step S17 of FIG.

After extracting the hyperlink address selected by the user (step S17 '), the markup page processing module 121 determines whether the file extension of the extracted hyperlink address is a preset application content corresponding extension (step S19'). This is a process for checking whether the hyperlink selected by the user is application content.

If it is determined that the file extension of the hyperlink address is not the extension corresponding to the application content (step S19 '), the markup page processing module 121 directly corresponds to the content corresponding to the hyperlink selected by the user in the content providing server 200. Request transmission of (step S21).

The content providing server 200 which has performed the login session authentication (step S23) transmits the content requested by the markup page processing module 121 (step S25).

The markup page processing module 121 analyzes the header of the content received from the content providing server 200 to determine whether the mime type included in the header is the application content mime type (step S27).

If the determination result is the application content mime type, the markup page processing module 121 stops the connection with the content providing server 200, executes the content processing module 122, and transmits the application content address and the content processing module 122 to the content processing module 122. The login session information is delivered to request the corresponding application content (step S29 ').

The following process, that is, the process of requesting and receiving the application content from the content relay conversion server 300 in the content processing module 122 is the same as the embodiment described with reference to FIG. 5 and will not be described.

The process from step S19 'to step S29' is described with a specific example as follows.

For example, if the tag content of the hypertext included in the markup page is "<a href=http://aaa.bbb/tmp.php>", then the extension php of tmp.php has the extension corresponding to the preset application content. No (ie, because it is not a format of pdf, doc, etc.), the markup page processing module 121 requests the content providing server 200 to transmit content using the corresponding address (aaa.bbb / tmp.php). do.

In response to the request, the content providing server 200 may transmit another markup page to the mobile communication terminal 100 or may transmit specific application content. In other words, for server script files (i.e. php files), we still don't know what kind of content will be sent.

What kind of content is transmitted is determined by the mime type included in the header of the transmitted content. For example, when using the HTTP (HyperText Transfer Protocol), the mime type "Content-Type: text / html" is a markup page. The mimetype "Content-Type: application / pdf" means a pdf document.

As such, the markup page processing module 121 that determines the type of the content transmitted from the content providing server 200 through the mime type of the header may be parsed and rendered itself if the corresponding content is a simple markup page. If it is determined that the content is an application content such as pdf, the user may request a corresponding application content by executing a pdf document viewer corresponding to the content processing module 122. In addition to the pdf format, the markup page processing module 121 may execute the pdf document viewer even in the case of document contents in various formats.

The pdf document viewer may request the content relay conversion server 300 for document contents of various formats. As described above, the content relay conversion server 300 converts the document contents of each different format into the pdf document format. Because of the transmission, there is no problem for the pdf document viewer to process the application content.

In the above-described embodiment, the application content is document content (pdf, doc, etc.) as an example, but the present invention is not limited thereto, and the application content may be variously changed by setting the type of the extension corresponding to the application content. Accordingly, the content processing module 122 is not limited to the pdf document viewer but may be a multimedia execution module. Also, when the single format converted by the content relay conversion server 300 is jpg format instead of pdf format, the mobile communication terminal Content processing module 122 of 100 may also be configured as an image viewer for processing a jpg image.

On the other hand, the present invention is not limited to the above-described specific embodiments and can be carried out by variously modified and modified within the scope not departing from the gist of the present invention. It will be apparent that such variations and modifications are included in the present invention as long as they belong to the appended claims.
