Description

Web content display apparatus and method in a mobile communication terminal {WEB-CONTENTS DISPLAY APPARATUS AND METHOD IN MOBILE COMMUNICATION TERMINAL SUCH AS PDA}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a web content display apparatus and method, and more particularly, to a web content display apparatus and method in a mobile communication terminal for efficiently displaying web content desired by a user on a display screen of a mobile communication terminal such as a PDA.

Recently, a web service for displaying Internet web contents on a mobile communication terminal such as a PDA or a mobile phone has been provided. As such, in order to provide web content on a mobile communication terminal, 1) a converter method and 2) a thin client method are widely used.

In terms of the converter method, for example, if a mobile phone is attached with a phone gateway for accessing an existing website, and the actual web site is accessed through the phone gateway, the web site may transmit the web content to another protocol such as WAP. After converting the data into a form, the mobile phone analyzes the WAP protocol and browses the web content on the screen.

The thin client approach is to create a screen on the server and send it to the client periodically so that the client sees only the screen that the server sends, allowing the user on the client side to use another computer as if it were a remote computer.

However, the web content providing service using a converter method and a thin client method in a conventional mobile communication terminal such as a PDA or a mobile phone has the following problems.

The converting method converts an existing HTML document into a form that can be viewed by a client. In this conversion process, a large portion of HTML tags are deleted and the shape of the corresponding content is significantly modified. Had to suffer the inconvenience of using the content. In particular, if the converter method is used in a terminal such as a PDA or a mobile phone, the HTML browser becomes very weak due to the above problems, so the user side is about 20% based on the total amount of data of the web content that can be viewed on a general desktop computer. Can only check the data on the terminal. In summary, there is a problem in that the data loss of the original web content is increased in the converter method, and this tendency becomes more serious for web content including many links.

The thin client method is a method of transmitting a portion of a typical desktop computer monitor screen to a mobile communication terminal such as a PDA, and thus a heavy network load. In addition, since the screen size of the displayed web content does not exactly match the LCD size of the terminal, it is not suitable for various PDAs, and thus, the user cannot efficiently use the displayed web content.

In conclusion, conventionally, in displaying web content on a mobile communication terminal such as a PDA or a mobile phone, since the web content is similar to the original image and could not be efficiently reduced / enlarged to fit the LCD size, the user may use a general PC. It was not able to feel the visual identity like this, and the network load is also great in the exchange of information between the necessary web server and the mobile communication terminal, which causes speed degradation and image quality deterioration. In addition, since there is no function of extracting and processing a specific part (ie, a specific text or a video) of the web content that the user specifically wants to enlarge or reduce, it is inconvenient to view the web content with a small terminal.

Therefore, there is an urgent need for a method for displaying web content more conveniently and efficiently in mobile communication terminals including PDAs.

Accordingly, the present invention has been made to solve the above-described problem, and provides a web content display apparatus and method in a mobile communication terminal for efficiently displaying a web content desired by a user on a display screen of a mobile communication terminal such as a PDA or a mobile phone. Its purpose is to.

In the embodiment of the present invention, the client terminal A embeds a separate client program for accessing the Internet 10 and receiving a web service from the server system B. In the case of a mobile communication terminal, the LCD screen size varies according to the product, and since a large program that runs on a general desktop PC does not work, a client program is generally made smaller.

When executed, the client program has a form similar to that of a file browser of a web browser or a window. When the user inputs a desired URL in the URL input window of the terminal while the client program is executed, the user is connected with the server system B. After the initial connection is performed, the SCTP (Scalable Contents-Transformer Platform) returned from the server side is performed. The operation depends on the type of protocol.

SCTP protocol is a protocol required for client terminal A and server system B to exchange data in order to process web pages according to the display screen sizes of various mobile communication terminals. Based. In the present invention, the SCTP protocol performs functions corresponding to the connection request / response section 5 of the client terminal A and the connection request / response section 11 of the server system B.

Next, the server system B according to the present invention will be described in detail.

The server system B is a program for establishing an environment for providing a web content display service on a mobile communication terminal. The server system B includes a web server 12 for transmitting data and processing input data for the web content display service; The connection request / response unit 11 for generating an Internet access request signal or responding to data requested by the client terminal A through the Internet 10, and a web page requested by the client terminal A.

Although not shown in the drawing, the server system B may also include a text input unit for processing a user's input of desired text in a web page displayed on a PDA terminal.

A method for displaying web content on a mobile communication terminal based on the system of FIG. 1 configured as described above is illustrated in FIG. 2 and will be described below. In addition, since a PDA is illustrated as an example of the client terminal A in FIG. 1, the client terminal A is referred to as a PDA terminal for convenience.

The user runs the web browser by executing the SCTP client program through the client terminal A (step S10), and inputs data such as a mouse, a button, or a stylus pen to the URL input window displayed on the PDA screen 2 (4). In step S12, a URL of a desired website is inputted using &quot;

The PDA-CPU 1 of the client terminal A transmits the input URL and its own terminal A information to the server system B via the connection request / response section 5 and the Internet 10 (step) S14). At this time, the information transmitted to the server system B side is URL information, device-specific device information (Deviceinfo: see FIG. 4), and service information (Serviceinfo: see FIG. 4). In particular, device information (Deviceinfo) is the terminal screen width. (width), screen height (height), color (color), and device identification information (ID).

Subsequently, the web server 12 of the server system B checks whether the URL information received by the connection request / response section 11 is the information previously inputted into the cache memory 16 (step S16). If the URL is cached in step S16, the web server 12 proceeds to step S24, withdraws the web page from the cache memory 16 and delivers it to the client terminal A of the user (step S24). After the terminal A displays the web page (step S24), the program ends.

If the URL is not cached in step S16, the web server 12 visualizes the web page requested by the user based on the information transmitted from the client terminal A, which are steps S18, S20 and S22 of FIG. It demonstrates with reference to. First, in step S18, a web page is expressed using a web browser. In detail, the web server 12 of the server system B receives a web page and an image corresponding to a URL, and then parses it in the parser 15. After the parsing process and the rendering operation in the rendering unit 14, the layout unit 13 creates a layout. Subsequently, the web server 12 receives the completed layout from the layout unit 13 and stores it as an image file with the corresponding web page (step S20), and transmits the imaged web page to the server in step S14. After converting the data into a form suitable for the terminal screen size according to the received terminal information, it is stored in the cache memory 16 (step S22).

Then, the web server 12 transfers the web page converted into a form suitable for the terminal screen size to the client terminal A of the user via the connection request / response unit 11 and the Internet 10 (step S24). After the client terminal A displays the web page as shown in FIG. 3 (step S24), the program ends.
