That is, even when the content file processor other than the web viewer requests the predetermined content file, the login session information is transmitted so that the content providing server can perform normal authentication processing.

In addition, the web viewer server compares the extension of a predetermined content file included in a hyperlink format on an Internet page, as well as a method for determining mime type information of a header of a response signal received from the content providing server. Even in the case of a content file whose extension is not revealed, an Internet link address of the corresponding content file is extracted and provided so that the browsing terminal can properly receive the corresponding content file through the content 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 comprises a browsing terminal 100, a web viewer server 200, a content conversion server 400, a content providing server 300 as shown in FIG. do.

Here, the content providing server 300 provides an internet page and a content file. An internet page includes a web page composed of text pages written in, for example, a markup language, and the markup language includes predetermined marks such as HyperText Markup Language (HTML), eXtensible Markup Language (XML), and Wireless Markup Language (WML). Anything that uses up tags to represent the content and structure of the document is included.

The content providing server 300 may be configured as a kind of web server, and as described below, a pre-stored Internet page (for example, a web page) or a request from the web viewer server 200 or the content conversion server 400 may be used. Provide a content file.

Here, the content file is processed in a specific application driven in the browsing terminal 100. For example, when the application driven in the browsing terminal 100 is a pdf document viewer program, the content file may correspond to a document file in pdf format. Can be.

When the web viewer server 200 receives the Internet page request signal from the browsing terminal 100, the web viewer server 200 accesses the content providing server 300 using the Internet page address included in the received Internet page request signal, and the content providing server 300. Parsing and temporarily storing the Internet page received from the Internet page, and generating and transmitting image data corresponding to the Internet page to the browsing terminal 100 based on the analysis result.

That is, the web viewer server 200 is provided between the communication terminal of the browsing terminal 100 and the content providing server 300 to convert the Internet page received from the content providing server 300 into an image to the browsing terminal 100. It is to perform the function of delivering.

At this time, the process of interpreting the Internet page includes the process of parsing and rendering the markup tag included in the Internet page, and the processed analysis result is temporarily stored and used as data in response to a request of the browsing terminal 100 later. do.

That is, when a link view request signal is received from the browsing terminal 100, the web viewer server 200 may interpret, for example, an internet link address corresponding to a predetermined coordinate value included in the link view request signal. Determining and extracting from the result, and transmitting the extracted Internet link address to the browsing terminal 100. A more detailed description of the link view request signal will be given later.

In this case, the web viewer server 200 includes a file extension list including predetermined file extensions in advance, and the above-described method is described only when the file extension of the extracted internet link address is the same as any of the extensions included in the file extension list. As described above, the extracted internet link address may be transmitted to the browsing terminal 100 as it is.

If the file extension of the extracted Internet link address is not the same as any of the extensions included in the file extension list, after accessing to the content providing server 300 and according to the access response signal received from the content providing server 300. The Internet terminal may transmit an internet link address or image data to the browsing terminal 100. A more detailed description thereof will be described later.

The content conversion server 400 relays the transmission of the content file between the content providing server 300 and the browsing terminal 100 and converts various types of content files into a predetermined specific format.

That is, when only one specific format is set in advance, the content conversion server 400 converts various types of content files received from the content providing server 300 into the set single format and then browses the terminal. Forward to 100.

This is to enable the browsing terminal 100 to process various types of contents of the content providing server 300 even though the browsing terminal 100 has a function of processing only contents of a specific format without having to support various types of formats. to be.

For example, the browsing terminal 100 has a function of viewing a pdf document. The content conversion server 400 converts all documents of various formats received from the content providing server 300 into a pdf format. If it is delivered to (100), the browsing terminal 100 processes all kinds of documents provided by the content providing server 300 regardless of the format (since it has already been converted to pdf format) to the user of the browsing terminal 100 You can have the document read.

The browsing terminal 100 is a terminal for allowing a user to browse an Internet page and use a predetermined content (specific file or game, etc.) included in the Internet page. 100 is an example of a mobile communication terminal such as a mobile phone, PDA (Personal Digital Assistants).

Accordingly, the browsing terminal 100 communicates with the web viewer server 200 and the content conversion server 400 through a wireless communication interval. The communication process through the base station, the mobile communication network, etc. of a predetermined mobile communication terminal is well known, so it is more detailed. Description is omitted. However, the web viewer server 200 and the content conversion server 400 may also be provided in the internet network like the content providing server 300.

The browsing terminal 100 according to the present invention does not have a parsing and rendering function for markup tags, and merely processes and displays the changed Internet page on the display unit 150. Accordingly, the browsing terminal 100 may be manufactured much simpler than a browsing terminal that performs parsing and rendering functions.

In particular, in the case of a portable wireless communication terminal such as a mobile phone, having only an image data processing function for processing an Internet page, such as the browsing terminal 100 according to the present invention, helps to reduce the size of the entire wireless communication terminal device.

In addition, the browsing terminal 100 generates a link view request signal according to a user's request and transmits it to the web viewer server 200. The link view request signal includes, for example, a browsing terminal in which a user displays an image of an Internet page. The click information (clicked coordinate value) clicked on the display of 100 may be included.

That is, when the Internet page in the form of an image received from the web viewer server 200 is displayed on the display unit of the browsing terminal 100, since the hyperlink on the displayed Internet page is also only pixel information in the form of an image, the browsing terminal For example, the user may not immediately extract hyperlink information of the clicked position, for example, and transmit the coordinate value of the clicked position to the web viewer server 200. Thereafter, an internet link address (ie, a hyperlink address) corresponding to the coordinate value of the position clicked by the user may be received from the web viewer server 200.

The browsing terminal 100 transmits a content file request signal including an internet link address received from the web viewer server 200 to the content conversion server 400, and from the content conversion server 400 according to the content file request signal. The received content file is processed and displayed on the display unit.

An example of the configuration of the browsing terminal 100 (that is, the mobile communication terminal) that performs the above function is illustrated in FIG. 2.

As shown in the figure, the browsing terminal 100 according to an embodiment of the present invention includes a communication interface 110, a control unit 120, a storage unit 130, a key input unit 140, and a display unit 150. It is configured to include.

The communication interface unit 110 is a component that enables wireless communication through a base station (not shown). The communication interface unit 110 transmits a signal generated by the control unit 120 to the base station, receives a predetermined signal from the base station, and controls the control unit 120. ) Function.

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.

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 web viewer 121 and a content file processor 122.

The web viewer 121 is a kind of image processor, and its main function is to process and display an Internet page made of image data on the display unit 150.

That is, the web viewer 121 displays the Internet page in the form of an image received from the web viewer server 200 on the display unit 150, and upon receiving a link viewing command from the user, requests the web viewer server 200 to view the link. Send a signal.

For example, the user may issue a link view command by clicking on the display unit 150 of the browsing terminal 100. The browsing terminal 100 detects this and then displays the clicked display unit 150. The link view request signal including the location information is transmitted to the web viewer server 200.

That is, as described above, the web viewer 121 does not have a function for processing markup tags by itself, and the displayed internet page is also only image data (ie, tag information is not included). Even if a certain content is included in a link structure on an Internet page in the form of an image, the link view request signal including the location information clicked on by the user is not immediately extracted by the user's click. To the web viewer server 200 to request the Internet link address of the content.

When the Internet link address is received from the web viewer server 200, the web viewer 121 delivers the Internet link address received from the web viewer server 200 while calling and executing the content file processor 122. In this case, predetermined session information may be received from the web viewer server 200. The session information is information necessary for authentication processing in the content providing server 300, as will be described later.

Here, the web viewer 121 and the content file processor 122 are types of programs that operate independently, and any one of them is not included in a module form in the other but can be executed independently. That is, the content file processor 122 may be executed independently and process the content file supported by the user regardless of whether the web viewer 121 is executed according to the user's selection.

The content file processor 122 driven according to the call of the web viewer 121 transmits a content file request signal including the Internet link address and session information received from the web viewer 121 to the content conversion server 400. A content file of a specific format received from the content conversion server 400 is processed and displayed on the display unit 150.

Here, the content file processor 122 may process only files of a specific format. For example, the content file processor 122 may be configured to process only document files in pdf format. In this case, if the content conversion server 400 converts various types of content files received from the content providing server 300 to pdf format and delivers them to the content file processor 122, the content file processor 122 is the content providing server. Regardless of the type of content file transmitted from 300, all of them can be processed.

Therefore, the user of the browsing terminal 100 can actually view various types of content files provided by the content providing server 300 using the browsing terminal 100 having a simple program capable of processing the pdf format. .

Meanwhile, as described above, the web viewer 121 and the content file processor 122 are independent programs, and session information of the content providing server 300 is shared between the web viewer 121 and the content file processor 122. Through the content conversion server 400 may be authenticated that the content providing server 300 has a legitimate right related to the content request.

If session information is not shared between two programs, for example, a content file included in web mail may not be properly received by the content file processor 122.

Here, the session information will be described in more detail as follows.

The session information is information provided by the content providing server 300 and may be generated, for example, after a login process is performed. That is, the content providing server 300 provides the session information to the corresponding terminal in order to maintain the connection of the terminals that log in to the terminal, and the terminal receiving the session information provides the session information to the content providing server 300 at a later connection. ) To prove that the device was successfully logged in before.

3A to 3C illustrate examples of packets generated during communication using a HyperText Transfer Protocol (HTTP) to explain a process of using session information.

First, FIG. 3A illustrates an example of data transmitted when a user inputs a user ID and password to log in to the JPO web site (www.kipo.go.kr), which is an example of the content providing server 300. That is, such data may be generated in the web viewer server 200 based on the information transmitted from the browsing terminal 100 and transmitted to the JPO web site server.

Although the browsing terminal 100 according to the present invention does not parse and render markup tags in web browsing but merely processes Internet pages converted into images in the web viewer server 200, a login ID and password An input field for inputting predetermined information such as may be displayed on the display unit 150. To this end, the web viewer server 200 may transmit a control signal for displaying the input field in the browsing terminal 100 when such an input form is present when the internet page is interpreted.

3B illustrates an example of response data transmitted from the JPO website server to the web viewer server 200 according to the login transmission as shown in FIG. 3A.

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 web viewer server 200. As such, the session information transmitted to the web viewer server 200 is included in the cookie header 154 when transmitted to the subsequent JPO website as shown in FIG. 3C, so that the JPO website is logged in based on the cookie or session information. Perform the process.

That is, the JPO site server determines whether to provide the requested content according to whether there is login session information.

As such, the login session information is information necessary to maintain a connection with the content providing server 300 that provides Internet pages and content files such as a web site on the Internet.

Hereinafter, a control process of a system for transmitting and receiving a content file connected to an internet page in a link structure according to an embodiment of the present invention will be described in detail with reference to FIG. 4. In the present embodiment, an internet page transmitted to the content providing server 300 is an example of a web page composed of markup tags. In addition, since the web viewer 121 and the content file processor 122 included in the browsing terminal 100 perform distinct functions, the sharing of login session information between the two is one feature of the present invention. The description will be divided into two.

First, the web viewer 121 transmits an internet page request signal to the web viewer server 200 according to a user's request (step S1). The request of the user may be, for example, an internet connection command including an internet address.

The web viewer server 200 accesses the content providing server 300 using the internet address included in the internet page request signal of the web viewer 121 (step S3). For example, the web viewer server 200 may access the content providing server 300 using the Internet address "http: //aaa.bbb/test.html".

The content providing server 300 performs a login process (step S5) and transmits an Internet page (that is, a test.html file) and login session information to the web viewer server 200 (step S7).

Here, in order to process the login in the content providing server 300, a process of providing a login page first and allowing a user to input the corresponding login page should be preceded.

The web viewer server 200 receiving the Internet page and login session information from the content providing server 300 parses and renders the markup tag of the received Internet page (step S9) and temporarily stores the processing result (step S9). S11) On the basis of the processing result, image data corresponding to the Internet page is generated (step S13).

The web viewer server 200 transmits the generated image data to the web viewer 121 (step S15). At this time, the web viewer server 200 may transmit the login session information to the web viewer 121, but since it is not necessary at this time, it is preferable to temporarily store it for later transmission.

The web viewer 121 receiving the image data from the web viewer server 200 processes the received image data and displays the received image data on the display unit 150 (step S17).

An example of a screen displayed on the understanding display unit 150 in the web viewer 121 is illustrated in FIG. 5A. As shown in the figure, a user of the browsing terminal 100 may view an e-mail using the web viewer 121.

Here, the screen illustrated in FIG. 5A is a screen converted into an image by the web viewer server 200 as described above. Therefore, the web viewer 121 does not know what content files are linked to the Internet page displayed on the display unit 150.

However, the user can only confirm as an image that there is an attached file on the screen.

When the user selects (eg clicks) the attachment to confirm the attachment attached to the e-mail, the web viewer 121 detects the user's link view command (step S19) and sends it to the web viewer server 200. The link viewing request signal is transmitted (step S21).

The link view request signal may include a coordinate value on the image screen clicked by the user.

The web viewer server 200 extracts the internet link address using the coordinate value included in the link view request signal (step S23). That is, the web viewer server 200 compares the Internet page interpretation result stored in step S11 with the user click position received from the web viewer 121 to know which link the user clicked, and the address of the clicked link. To extract it.

If it is determined that the file extension of the extracted internet link address is a file extension included in the preset file extension list (step S25), the web viewer server 200 transmits the extracted internet link address to the web viewer 121. (Step S33).

For example, if the previously stored file extension list includes "pdf, doc, hwp, gul", the web viewer server 200 has the extracted Internet link address "http: //aaa.bbb/bestpractices." doc ", the file extension of the Internet link address is 'doc', and the file extension in the file extension list is determined, and the extracted Internet link address" http: //aaa.bbb/bestpractices.doc "is displayed in the web viewer (121). To send).

In this case, the web viewer server 200 may transmit the temporarily stored login session information together with the Internet link address.

The web viewer 121, which has received the internet link address from the web viewer server 200, transfers the internet link address to the content file processor 122, which also transmits the login session information (step S35).

For example, when using the HTTP, the web viewer server 200 transmits an internet link address using a 'Location' header, that is, "Location: http: //aaa.bbb/bestpractices.doc". The web viewer 121 that detects the Location 'header detects that an internet link address for the content file is received from the web viewer server 200 and transfers the corresponding internet address to the content file processor 122.

Since the web viewer 121 does not have a function for processing a content file, a separate program (hardware or software) with a content file processing function is driven, and the login session information for the Internet address of the content file and the authentication process are provided. To convey.

In this embodiment, it is assumed that the content file processor 122 has a function of processing a pdf document file of a specific format, for example, Adobe.

As an example in which login session information is shared between the web viewer 121 and the content file processor 122, the web viewer 121 stores the login session information in a specific location of the preset storage unit 130 and the content file processor. When the request for driving 122 is performed, the driven content file processor 122 may read the specific location of the preset storage 130 to obtain login session information.

The content file processor 122 that receives the Internet link address (ie, the Internet address of the content file) and the login session information from the web viewer 121, sends a content file request signal including the received Internet link address and the login session information. The transfer is sent to the content conversion server 400 (step S37).

The content conversion server 400 requests the content providing server 300 to transmit the content file based on the Internet link address included in the content file request of the content file processor 122 (step S39). At this time, the content conversion server 400 delivers the login session information together.

The content providing server 300 determines whether the request is an authorized request for the corresponding content file based on the login session information received from the content conversion server 400 (step S41). The transfer is performed to the conversion server 400 (step S43). For example, when the Internet link address that the content conversion server 400 accesses is 'http: //aaa.bbb/bestpractices.doc', the content providing server 300 may refer to a corresponding content file, that is, 'bestpractices.doc'. Deliver Word document files from Microsoft Corporation.

The content conversion server 400 that receives the word document file from the content providing server 300 converts the file into a specific single predetermined format (step S45). For example, when the preset format is 'pdf', 'bestpractices.doc' Convert Word document files to Adobe's pdf document files.

Of course, the specific format preset in the content conversion server 400 is not limited to the 'pdf' format.

Meanwhile, after converting to pdf format, the content change server transmits the converted file, for example, the bestpractices.pdf file, to the content file processor 122 (step S47).

In the present embodiment, the content file processor 122 may process a file in pdf format, and thus, the content file processor 122 that receives the bestpractices.pdf file from the content conversion server 400 processes the file, and thus, FIG. It may be controlled to be displayed on the display unit 150 as well (step S49).

Accordingly, the browsing terminal 100 according to the present embodiment includes a web viewer 121 for simply processing an Internet page in the form of an image and a content file processor 122 for processing a pdf file. There is no inconvenience in browsing the Internet pages it contains.

Hereinafter, a control flow of a transmission / reception system of a content file connected to an internet page in a link structure according to another embodiment of the present invention will be described with reference to FIG. 6.

Since this embodiment is similar in many respects to the previous embodiment with reference to FIG. 4, detailed description of the similar contents is omitted.

Steps S1 'to S23' correspond to steps S1 to S23 of FIG.

Subsequently, the web viewer server 200 determines whether the file extension of the extracted Internet link address is included in the preset file extension list (step S25 '). For example, in the preset file extension list, "pdf, doc, hwp, gul "and the extracted Internet link address is 'http: //aaa.bbb/test.php', the extension 'php' of the file 'test.php' is added to the preset file extension list. Since it is not included, the web viewer server 200 first connects to the content providing server 300 with the address 'http: //aaa.bbb/test.php' (step S27).

The php file is a kind of server script file, and the content providing server 300 interprets the script content of the self-stored file called test.php to generate a new internet page or content file, and generates the Internet as a response signal to the image viewer server. The page or content file is transferred (step S29).

The web viewer server 200 determines whether it is an Internet page or a content file transmitted from the content providing server 300 as a connection response signal (step S31). The connection response of the content providing server 300 is determined as the determination method. You can check the Multipurpose Internet Mail Extensions (MIME) type of the header included in the signal.

For example, if the http header includes a content that knows the mime type of "Content-Type: application / msword", the web viewer server 200 receives the data received from the content providing server 300 from Microsoft's ms. It is determined that the file is in word format.

In this case, the web viewer server 200 blocks the connection with the content providing server 300 and transmits the extracted address "http: //aaa.bbb/test.php" and login session information to the web viewer 121 ( Step S33 ').

Since the following process, that is, the browsing terminal 100 receives the file converted into the pdf format from the content providing server 300 through the content conversion server 400 using the Internet link address is the same as the previous embodiment Omit the description.

On the other hand, the web viewer server 200 is received from the content providing server 300, when the "Content-Type: text / html" is included in the header of the connection response signal received from the content providing server 300. Since it corresponds to a general Internet page, the Internet page may be parsed and rendered as in steps S9 'to S15', the result may be stored, changed into an image, and transmitted to the web viewer 121.

In the above embodiments, the content file is a document content (pdf, doc, etc.) as an example, but the present invention is not limited thereto, and may be variously changed by setting the type of the extension corresponding to the content file. Accordingly, the content file processor 122 is not limited to the pdf document viewer but may be a multimedia execution module.

If the browsing terminal 100 is an apparatus for processing an Internet page, the browsing terminal 100 is not limited to a wireless terminal such as a mobile phone, and may include various devices.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention. If such changes and modifications fall within the scope of the appended claims, it will be apparent that they are included in the present invention.
