The present invention relates to wireless Internet technology, and more particularly to a portable terminal for providing a wireless Internet service.

With the widespread use of the Internet, the rapid development of portable terminal performance and network speed, mobile communication services provide not only simple voice calls but also wireless Internet services such as ringtone download, image download and network game.

For the wireless Internet service, the portable terminal has a built-in browser, and the user accesses a web server using a browser embedded in the portable terminal to receive wireless internet services such as ringtone download, image download, and network game as described above. .

However, the screen display unit of the portable terminal has a small absolute size in accordance with the pursuit of portability of the terminal, and there is a limit to displaying various information on one screen. For example, when using wireless Internet content such as news or newspaper article as a browser of the portable terminal, the screen display unit of the portable terminal is small enough to display a large amount of text content such as the news or newspaper article on one screen. The text content should be viewed by moving the page with the up / down keys or the up / down scroll keys.

However, when the page is moved using the page up / down key or the up / down scroll key in the portable terminal, the text data is displayed by being moved by about half a page. Accordingly, there is a problem in that each time the page is moved, the user has to repeatedly find out where the previously viewed contents are located in the moved page.

In order to solve this problem, a technology for displaying scroll information in the form of a scroll bar displaying a current position when displaying text data on a screen display unit of a portable terminal has been developed.

1 is a diagram illustrating an example of displaying scroll information on a screen of a portable terminal according to the prior art. When text data is displayed on a screen display of a portable terminal, as shown in FIG. Which position of the full text data is displayed via the scroll bar 101.

However, the method of displaying the position of the text data through the scroll bar 101 only indicates the extent of the text data range currently displayed, but only when the page moves based on the half page as described above. It doesn't tell you exactly where you are on the page you're viewing.

The present invention has been proposed to solve the above problems, and provides a portable terminal and a method for automatically classifying and displaying pages so that the position of the data viewed immediately before the page movement of the data displayed on the screen can be easily identified. There is this.

Other objects and advantages of the present invention can be understood by the following description, and will be more clearly understood by the embodiments of the present invention. Also, it will be readily appreciated that the objects and advantages of the present invention may be realized by the means and combinations thereof indicated in the claims.

According to an aspect of the present invention, there is provided a portable terminal for providing page division when outputting data, comprising: display means; Storage means for storing data; A browser application for reconfiguring the data selected by the user to fit the screen size of the display means and moving the page; And page dividing means for finding the last token of the previous page in the moved page and displaying an identifier for distinguishing the page at the corresponding position when the page of the data is moved.

In addition, the present invention provides a method for providing page classification when outputting data by a browser application in a portable terminal, wherein the data selected by the user is reconfigured to fit the screen size of the portable terminal and output on the screen, A first step of storing the last token; A second step of receiving an input for page movement from a user; And a third step of page shifting the data being output on the current screen. And a fourth step of searching for the last token stored in the first step in the moved page and displaying an identifier for distinguishing a page at a corresponding position.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings, whereby those skilled in the art may easily implement the technical idea of the present invention. There will be. In addition, in describing the present invention, when it is determined that the detailed description of the known technology related to the present invention may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a block diagram of a portable terminal according to an embodiment of the present invention. As shown in FIG. 2, the portable terminal according to the present invention includes an RF unit 200, a key input unit 220, a handset unit 240, The memory 260 includes a display unit 270 and a control unit 290. Such portable terminals include PDAs, cellular phones, PCS phones, GSM phones, W-CDMA phones, DMB (Digital Multimedia Broadcasting) phones, and the like.

The RF unit 200 transmits / receives an RF signal, and converts the RF signal received from the base station through an antenna (not shown), down-converts the frequency signal, demodulates it into a digital signal, and transmits the baseband signal transmitted from the control unit 290. The signal is modulated and converted into an analog signal, and then frequency-converted and transmitted to the base station as an RF signal.

At this time, when the user uses the wireless Internet service using the portable terminal, the base station connects the web server for providing the wireless Internet service with the portable terminal according to the present invention to enable the wireless Internet service. Wireless internet content transmitted from a web server, for example, text data such as news and newspaper articles, is received through the RF unit 200 and stored in the memory unit 260.

The key input unit 220 includes a plurality of keys for inputting various commands or dialing by a user, and generates and transmits key data according to the key input to the controller 290.

The handset 240 is a circuit for a voice call, and includes a microphone and a speaker, and converts and outputs an electrical signal into an audible sound or converts and outputs a voice signal into an electrical signal.

The memory unit 260 stores a control program, a mobile platform, various applications, and various data for controlling the overall operation of the portable terminal. The memory unit 260 preferably includes a read only memory (ROM), a random access memory (RAM), and an electrically erasable programmable read only memory (EEPROM). The browser application 261 for browsing the wireless Internet is preferably stored in a read-only memory (ROM) in which stored data is not deleted / changed even when power is not supplied. Of course, the browser application 161 may be implemented in hardware circuitry.

On the other hand, the temporarily downloaded data, such as the content downloaded from the web server is preferably stored in a random access memory (RAM) in which the stored data is deleted when the power is not supplied, the read-only memory reads the downloaded content according to the user's command (ROM) can be stored. Content stored in read-only memory (ROM) can be viewed again until deleted by the user.

The browser application 261 stored in the memory unit 260 connects to a wireless Internet web server according to a user command input through the key input unit 220, and contents, for example, text contents such as news and newspaper articles, or The image content is downloaded and displayed on the display unit 270. In addition, the display unit 270 displays content previously stored in the memory unit 260 according to a user command input through the key input unit 220.

In this case, the read-only memory (ROM) of the memory unit 260 stores identifiable user interface elements such as lines and bars for dividing the pages of the downloaded content. When the downloaded content is displayed on the display unit 270, the page division module 262 implemented in the browser application 261 displays the user interface element in the last content portion of the previous page so that the user can move the page. Make sure the location of the content you are currently viewing is clearly recognizable.

That is, the browser application 261 parses the content downloaded from the web server and temporarily stored in the random access memory (RAM), or the content previously stored in the read-only memory (ROM) of the memory unit 260. In other words, a source such as a programming language describing the content is interpreted according to a predetermined grammar. For example, in the case of content described in HTML, each tag is parsed by classifying the syntax described in the HTML document, in particular, all tags (including image tags) by referring to the HTML Document Type Definition (DTD). The browser application 261 renders the parsed content to fit the screen size of the display unit 270. That is, the content is reconstructed according to the screen size of the display unit 270 using the parsed content and the location information file (for example, CSS and HTML tags) and displayed on the display unit 270.

However, in general, since the data size of the content is larger than the screen size of the display unit 270, the user inputs a scroll key to view the contents of the content by gradually descending the page. When the user inputs a scroll key, the browser application 261 scrolls down about half a page and displays it on the screen. In this case, the page separator module 262 implemented in the browser application 261 remembers the last token of the content displayed on the screen before scrolling down, finds the last token in the scrolled content, and locates the corresponding location. Identifies user interface elements such as lines and bars. When the user finds only the user interface elements on the screen, the user can easily determine the location of the content to be viewed on the currently displayed screen. The user interface element for page division may hinder the user from viewing the content. Therefore, it is preferable to activate and disappear for about 1 second.

FIG. 3 is a diagram illustrating an example of displaying a UI element capable of identifying a page at the end of a previous page. FIG. 3A illustrates a previous page screen, and FIG. 3B illustrates FIG. 3A. ) Scrolls down the screen by half a page and displays the last page by using a line, and FIG. 3C shows a screen displaying the last page by using a bar unlike FIG. 3B. Indicates.

As shown in (a) of FIG. 3, a user who views all the text documents displayed on the display unit 270 of the portable terminal inputs a scroll down key to view the next text document. Then, the browser application 261 scrolls down the currently displayed text document by about half a page and subsequently displays the next text document at the bottom of the text document being displayed on the screen. In addition, the page separator module 262 displays a line 301 as shown in FIG. 3B between the last line of the existing text document and the first line of the next text document which is scrolled down and displayed on the screen. The last line of the text document viewed at is displayed as a bar 302 (eg, shaded) of a different color from the background screen, so that the user can easily locate the text document viewed before scrolling down.

4 is a diagram illustrating another example in which a page divider line is displayed at the end of a previous page, and a portable terminal downloads news from a web server and displays an example on the screen.

FIG. 4A illustrates a first part of news displayed on a screen of a portable terminal. A user who reads all the news displayed in FIG. 4A enters a scroll down key and receives a scroll down key. The browser application 261 scrolls down the page by about half a page. In this case, the page division module 262 of the browser application 261 memorizes the last line of the news shown in FIG. 4 (a). When the news article is scrolled down as shown in FIG. A line 401 for separating pages is displayed at the position of the line. When the user who has read all the news articles in FIG. 4B again inputs a scroll down key, the browser application 261 scrolls down the page by about half a page again. In this case, the page division module 262 also stores the last line of the news, that is, the "Multimedia CN" line shown in (b) of FIG. On the scrolled down screen, a line 402 for separating pages is displayed below the memorized line. Thus, when turning a page of a text document, an identifier for distinguishing a page is displayed on the last line of the text document that was previously displayed on the screen, so that the page is moved irregularly so that the user can relocate the text where he or she has seen. It solves the hassle of having to read from the line again.

5 is a flowchart illustrating a page classification method in a portable terminal according to an embodiment of the present invention.

As shown in FIG. 5, first, a browser application 261 of a portable terminal accesses a web server providing a wireless Internet service (S501), and downloads wireless Internet content from a web server according to a user's input (S503). ).

Next, the browser application 261 of the portable terminal parses the content downloaded from the web server and reconstructs the parsed content according to the screen size of the portable terminal and displays it on the screen (S505).

The page separator module 262 implemented in the browser application 261 of the portable terminal stores the last token of the content currently displayed on the screen of the portable terminal (S507).

Since the size of the content downloaded from the web server, for example, a text document such as news, is larger than the screen size of the portable terminal, the user enters a scroll key to move the page to view all the contents.

Accordingly, the browser application 261 of the portable terminal scrolls down the content currently displayed on the screen by about half a page according to the user's scroll key input (S509). For example, a user who views all of the text data displayed on the screen of the portable terminal as shown in FIG. 4A inputs a scroll key, and thus the browser application 261 reads the text document as shown in FIG. 4B. Scroll down to display half a page.

Subsequently, the page classification module 262 implemented in the browser application 261 of the portable terminal finds the last token stored in the step S507 in the content displayed on the screen by scrolling down in the step S509 and displaying a line, a bar, or the like at the corresponding position. An identified user interface element is displayed (S511). For example, the last line of the text data displayed as shown in FIG. 4A is stored, and the last line stored while scrolling down and displaying the next page as shown in FIG. 4B according to a user's scroll key input. Displays page breaks at the position of.

In addition, the page separator module 262 implemented in the browser application 261 of the portable terminal stores the last token of the content displayed on the screen in step S511 again, and the user's scroll key is input again to the browser application 261. When the page is scrolled down, the last token memorized is found in the content displayed on the scrolled down screen, and the identifiable user interface elements such as lines and bars are displayed at the corresponding positions. This process is repeated until the user sees all the downloaded content, so that even if the page is moved, the location of the currently viewed content can be quickly recognized. In this case, the identifiable user interface elements are preferably displayed for about 1 second and then disappear automatically so as not to disturb the user from viewing the content.

In this case, the portable terminal accesses a web server through a wireless Internet and describes how to display the downloaded content by displaying a page. However, the contents previously stored in the memory unit 260, for example, a tent document and an image, are described. Etc. can be displayed on a page separated page. In this case, the browser application 261 of the portable terminal parses the content selected by the user among the contents previously stored in the memory unit 260, and reconfigures the parsed content according to the screen size of the portable terminal and displays it on the screen. Then, the steps S507 to S511 are performed.

As described above, the method of the present invention may be implemented as a program and stored in a recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.) in a computer-readable form. Since this process can be easily implemented by those skilled in the art will not be described in more detail.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the technical spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited by the drawings.

The present invention as described above, by displaying an identification element that can be identified between the previous screen and the next screen when displaying wireless Internet content such as a text document on the small screen of the portable terminal, the content displayed on the screen of the portable terminal It is effective to increase the activation of the wireless Internet service to increase the convenience of the user.
