Recently, with the rapid development of mobile communication, mobile phones are widely used as mobile communication terminals, and various types of information can be shared by accessing the wireless Internet through such mobile phones.

When a mobile web server is used to access a wireless web server and a desired web page is provided, the mobile phone displays the information of the web page on the screen according to a default font set at the time of manufacture or a font acquired and set later by the user. .

Therefore, in the related art, only a font almost uniformly expressed in a wireless web page can be accessed by a user through a mobile phone. Therefore, there is a limit in expressing the personality of the wireless web page even when constructing a wireless web page.

Accordingly, the present invention has been made to solve the above-described problems of the prior art, and even when the font of the web page is not supported by the mobile communication terminal when accessing the web page automatically downloads the font of the web page font. The purpose of the present invention is to provide an adaptive web font service system for displaying a web page, a method of providing the service, and a mobile communication terminal applicable to the service.

In order to achieve the above object, the adaptive web font service system according to the present invention is operated by a web browser according to a user's operation, and receives and displays a desired web page through a communication network, wherein the web browser receives the provided web page. If the font is not supported by the font of the web page, the web page font resource is requested to be provided through the communication network to the font providing server, and the font resource is provided from the font providing server. A mobile communication terminal displaying a page; After compressing and converting various types of font resources into a format for downloading, and having web pages constructed on the basis of various types of font resources guaranteed through the quality assurance process, the web pages requested from the mobile communication terminal Wireless web server provided to the terminal; After compressing and converting various types of font resources into a format for downloading, storing various types of font resources guaranteed through the quality assurance process, and receiving a predetermined web page font resource request from the mobile communication terminal, the corresponding font resources are applied. Characterized in that the mobile communication terminal comprises a font providing server provided through a communication network.

In order to achieve the above object, the adaptive web font service method according to the present invention comprises: a first step of compressing and converting various types of fonts into a format for download in a font providing server and storing the fonts as font resources; A second step of the web browser analyzing the web page provided as the web browser is driven by the user's operation and connected to a predetermined web server through a communication network to request a desired web page; A third step of requesting, through a communication network, a font providing server to provide a font resource of the web page when the font of the web page is determined to be a font not supported by the mobile communication terminal in the second step; A fourth step of providing a corresponding font resource to a corresponding mobile communication terminal through a communication network when a request for providing a predetermined web page font resource is received by the font providing server; And a fifth step in which the web browser displays the web page using the font resource provided from the font providing server in the mobile communication terminal.

In order to achieve the above object, a mobile communication terminal according to the present invention includes a key input unit; A communication module for communicating data through a wireless network; A memory in which an operation program including a web browser program and a data including a control program and font data are stored; Display means; And control means for controlling various operations according to an operation signal from a key input unit and controlling a web page provided by accessing a web server through a communication module to be displayed through a display means by driving a web browser. Come on in; The control means receives a desired web page by accessing a web server through a communication network by driving the web browser according to a user's web browser driving request from the key input unit, and analyzing the received web page by the web browser. If the font of the web page font is not supported font resource requests to provide the font resource of the web page through the communication module to the font providing server through the communication network, the web using the font resources provided from the font providing server And control a page to be displayed on the display means.

Hereinafter, an adaptive web font service system, a service providing method thereof, and a mobile communication terminal applicable to the service will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the adaptive web font service system of the present invention includes a mobile communication terminal 10, a wireless web server 20, and a font providing server 30.

The mobile communication terminal 10 has at least a function of driving a web browser to access the web server 20 through a communication network to receive and display a desired web page. The mobile communication terminal 10 analyzes the web page provided from the web server 20 by the web browser, and the font providing server when the font constituting the web page is a font resource not owned by the web browser. 30) to provide a corresponding web page font resource through a communication network, and displays the web page using the font resource provided from the font providing server 30.

Here, the web page is Hypertext Markup Language (HTML) and / or eXtensible Hypertext Markup Language (XHTML) and / or mobile Hypertext Markup Language (mHTML) and / or Wireless Markup Language (WML), and the font name and Font file providing account information (ie, font providing server account information) may be included in the following format.

First, the format using "CSS (Cascaded Style Sheet)" is as follows.

<style type = "text / css">

<!-

    @ font-face {font-family: font name;

src: url (http: //fontfileprovider/webfont.utf);}

    body {font-family: font name; font-size: 9pt; line-height: 150%;}

    td {font-family: font name; font-size: 9pt; line-height: 160%;}

->

</ style>

And second, the format of using "basefont TAG" is as good as it looks.

<base href = "http: //fontfileprovider/webfont.utf">

<basefont face = "font name">

Third, the format using "special HTML Tag" is as follows.

<webfont face = "font name" src = "url (http: // font file provider / webfont.utf)">

On the other hand, the web browser is preferably a browser that supports at least one of HTML, mHTML, XHTML and WML, the mobile communication terminal 10 by analyzing the web page provided by the wireless web server 20 HTML acquires the font name and font file providing account (i.e., the corresponding font providing server account) included in the mHTML, XHTML and / or WML sentence, and accesses the font providing server 30 using the font file providing account to access the font. Provides the font name and the corresponding web page account to the providing server 30 to request the font of the web page, the font providing server 30 from the wireless web server 20 using the corresponding web page account information Receives a web page, extracts letters and special characters included in the web page, and only corresponding fonts corresponding to the extracted letters and special characters as font resources And transmits it to 10. Accordingly, the mobile communication terminal 10 sets the font received from the font providing server 30 as a temporary font of the terminal, and outputs the web page as the temporary font, according to the user's operation. When the screen display is finished, the temporary registered font is deleted. Here, at the end of displaying the web page, the temporarily registered font may be cached according to a predetermined period or a predetermined rule.

On the other hand, the wireless web server is provided with a myriad of web pages built on the basis of various types of font resources guaranteed through the quality assurance process after compression conversion of various types of font resources into a format for download. Such a web page may be a user homepage, and the user homepage may be configured using a unique font selected by the user. The web page constructed using such a unique font may not be properly displayed by basic font resources mounted at the time of manufacture of a general mobile communication terminal (ie, a mobile phone).

The wireless web server 20 provides a web page requested from the mobile communication terminal 10 to the corresponding mobile communication terminal 10. Here, the web page provides a font name and a corresponding font file constituting the web page by using the "CSS (Cascaded Style Sheet)" method, the "basefont TAG" method, the "special HTML Tag" method, etc. described above by way of example. Contains account information (ie, font-providing server account information).

The font providing server 30 compresses and converts various types of font resources into a format for download and stores and manages various types of font resources guaranteed in the database 35 through a quality assurance process, and the mobile communication terminal 10. When a request for providing a predetermined web page font resource is received from the web server 20, the web server 20 requests the web page to be provided, extracts the characters and special characters included in the provided web page, and the request corresponding to the extracted characters and the special characters. The read font resource is read from the database 35 and provided to the mobile communication terminal 10 through a communication network.

2 is a view for explaining a procedure for building a database of web fonts provided by the service of the present invention.

As shown in the figure, first, various types of fonts are continuously provided from a contents provider (CP) (step 40), and the converted fonts are compressed and converted into a form suitable for download using a font converter. (Step 42).

Here, the font may use bitmap font and vector font. The bitmap font (dot font) can be made in fine detail by expressing it as a single point, but if the font size is increased than the existing setting, it becomes like a square mosaic screen, and the amount of data is large and the size is changed. It's inconvenient to do this, so I usually use only the information of Yoon Kwan-seon to fill the middle of printing. The vector font is a character formation method that generates the direction and position of a line by a mathematical method rather than expressing the character outline as a fixed point, and because the character is created by mathematical logic, the size increases as the screen size increases. Accordingly, the text size is increased by being interlocked, which has the advantage that there is no change in the text image. In the following description, a vector font is used as an example.

Meanwhile, the compression conversion of the font can be implemented using a specific font converter. In this font converter, the input vector font image is divided into Chojung, Neutral, and Jongsung in Korean, and the duplicated images are compressed and stored as one. You can do that. You can store the control point (coordinate information) of the vector in 1 byte and draw the text in a 256 × 256 grid.

Thereafter, a quality assurance (QA) test is performed on the compressed and converted vector font image. In this quality assurance (QA) test, the font is inspected systemically and visually (step 44). In this case, the quality standards of the font to be inspected may be considered as follows. That is, it is possible to consider whether the width of the font is correct, does not cause a problem in the terminal, whether the font identification code is correct, whether a fixed width font (ie, a bitmap font) is included.

Through this quality assurance check, a quality guaranteed font can be obtained (step 46), and the quality guaranteed vector font is stored and managed in the database 35 of the font providing server 30.

Next, the adaptive web font service method according to the present invention will be described in detail with reference to FIGS. 4 and 5.

First, as described above, various types of fonts are compressed, converted into a format for download, and after quality assurance, they are stored and managed as font resources in the database 35 of the font providing server 30.

As the user manipulates the key input unit 52 of the mobile communication terminal 10, the control unit 54A of the control unit (MCU) 54 drives the wireless web browser program stored in the memory 53 to communicate with the communication module 51. Attempts data communication with the predetermined wireless web server 20 via the request to request a desired wireless webpage connection (step S41).

The web server 20 provides a corresponding web page in response to a request from the mobile communication terminal 10 (step S42). Here, the web page is XHTML (eXtensible Hypertext Markup Language) and / or WML (Wireless Markup Language). As described above, the web page may be a "CSS (Cascaded Style Sheet)" method, a "basefont TAG" method, " The font name constituting the web page and the font file providing account information (that is, the font providing server account information) are included using a special HTML tag.

The control unit 54A of the mobile communication terminal 10 receiving the web page from the web server 20 through the communication module 51 performs a web page analysis by a web browser to configure the font of the web page. The name and font file providing account information (ie, font providing server account information) are extracted and stored in the temporary storage area 54B, and the font corresponding to the extracted font name is stored in the temporary storage area 54B and / or the memory 53. (I.e., check whether the mobile communication terminal 10 supports the extracted font) (step S44).

If it is confirmed in step S44 that the font exists, the flow proceeds to step S51 described later. On the other hand, if it is determined in step S44 that the font does not exist, the control unit 54A of the mobile communication terminal 10 uses the extracted font file providing account information (ie, font providing server account information). Access to the font providing server 30 provides the account information and the font name of the web page, and requests the font providing server 30 to provide the font for the web page (step S45).

The font providing server 30 accesses the wireless web server 20 by using the account information of the corresponding web page provided by the mobile communication terminal 10 and requests the corresponding web page (step S46). The web page is provided from the web server 20 (step S47).

Thereafter, the font providing server 30 extracts characters and special characters included in the web page provided from the wireless web server 20 (step S48), and for each of the extracted characters and special characters, respectively. Fonts corresponding to the font name requested by the mobile communication terminal 100 are extracted from the database 35 and transmitted to the corresponding mobile communication terminal 10 through the communication network (step S49).

Accordingly, the control unit 54a of the mobile communication terminal 10 having received the font through the communication module 51 registers and stores the received font as a temporary font in the temporary storage area 54B. Thereafter, the display driver 55 is controlled such that the web page is displayed and output on the display unit 56 using the font registered as the temporary font (step S51).

Thereafter, the control unit 54a of the mobile communication terminal 10 terminates the temporary font registration setting stored in the temporary storage area 54B when the exposure to the display unit 56 for the corresponding web page is terminated by a user request. The font is deleted (step S53). Here, at the end of displaying the web page, the temporarily registered font may be cached and deleted according to a predetermined period or a predetermined rule.

On the other hand, in the above specific embodiment, the mobile communication terminal 10 analyzes the web page provided from the web server 20 to obtain the font name included in the sentence of the web page and the corresponding font providing server account information, and the font providing server account. Access the font providing server 30 using the information to provide the web page account information and font name, and request the font of the web page, the font providing server 30 by using the web page account information Receives the web page from the wireless web server 20, extracts the characters and special characters included in the web page, and only the corresponding font corresponding to the extracted characters and characters to the mobile communication terminal 10 as font resources. It is supposed to transmit. However, the mobile communication terminal 10 analyzes the web page provided from the web server 20 to obtain the font name included in the sentence of the web page and the corresponding font providing server account information, and uses the font providing server account information to obtain the font. All font resources corresponding to the requested font name among the font resources previously stored and retained are provided by the providing server 30 and providing the acquired font name and the font providing server 30 is stored. May be transmitted to the mobile communication terminal 30. This may be useful when the size of all font resources corresponding to the font is small.

On the other hand, the present invention is not limited to the above-described specific embodiments and can be modified and modified in various ways without departing from the gist of the present invention, which is included in the appended claims. It is obvious that if belonging to the present invention.

As described above, according to the present invention, even when a font of the web page is not supported by the mobile communication terminal when the web page is accessed, the web page font is automatically downloaded so that the web page can be displayed with the font. By providing an adaptive web font service system, a service providing method thereof, and a mobile communication terminal applicable to the service, it is possible to construct a wireless web page so that individual characters can be sufficiently expressed in various fonts.
