Internet access device and method for providing full browsing service in mobile communication terminal {Internet browser to provide full internet service for mobile equipment}

The present invention relates to an internet access device and a method for providing an internet environment similar to that of a PC in a mobile communication terminal using an internet browsing server.

Recently, due to the development of mobile communication terminals, the use of the Internet in mobile communication terminals has become commonplace. However, the CPU or memory used in the mobile terminal is relatively smaller than the CPU or memory used in the PC and the storage space is smaller, making it difficult to use the Internet browser used in the PC as it is. This has been. In addition, Internet browsers such as Internet Explorer and Mozilla, which are widely used at present, are not only large but also support too many kinds of plug-ins such as active axe. In addition, most domestic web environments are optimized for MS Explorer, and the full Internet browser for mobile communication terminals (Full Internet Browser: There have been many limitations in creating a browser for a mobile terminal that supports all the features of an Internet browser on a PC. For this reason, the Internet browser currently used in the mobile communication terminal uses a text-based Internet browser different from the image-based Internet browser used in the PC.

The present invention is to solve the inconvenience of the text-based Internet browser used in the mobile communication terminal as described above. That is, the present invention provides a full browser capable of providing a hypertext environment to a user by analyzing an HTML document such as an Internet browser used in a PC, and is fast and secure in a mobile communication terminal having a relatively small amount of calculation and a small memory. An object of the present invention is to provide an internet access device and a method for providing an internet full browsing service for a mobile communication terminal for operation.

In order to solve the above problems, the present invention includes an Internet browsing server that can be accessed from a mobile communication terminal through a wireless Internet network, the Internet browsing server can communicate with the mobile communication terminal through the terminal communication manager, rendering Through the agent, you can access the wired internet network.The user receives the internet address you want to access from the mobile communication terminal through the wireless communication network through the terminal communication manager, and assigns a rendering agent to send the internet address to the rendering agent. After the agent downloads an Internet page using a wired Internet network, the agent converts the entire downloaded page into a chunked image and transmits it to the mobile communication terminal. In addition, the rendering agent cuts and transmits the screen image in chunks when the screen image is transmitted to the mobile communication terminal, and may periodically transmit the entire screen image, transmit the full screen image only once, and then only the changed chunk image. have. In addition, the mobile communication terminal may transmit only the chunk image displayed in the screen window, or may change only the chunk image changed among the chunk images displayed in the mobile communication terminal. These various chunk image transmission forms may be selected according to the user's Internet usage pattern. In addition, since an anchor existing in the HTML document is separately analyzed by the rendering agent and only its coordinate values are converted into metadata and transmitted to the mobile communication terminal, a smaller amount of data is transmitted than the entire HTML document is transmitted. Can provide a hypertext environment.

As described above, the present invention not only provides an image-based internet, but also a text-based internet, in a mobile communication terminal, and can be used in a mobile communication terminal similarly to using an HTML-based Internet page in a PC. Provided are an internet access device for providing a browsing service and a method thereof. In addition, since a single page of the Internet is generated as a single image, it is converted into a chunk image unit and transmitted to the mobile communication terminal, and after the initial transmission, only the chunk image of the changed part in the chunk image unit is transmitted. Since the anchor in HTML document is converted into meta data and transmitted to the mobile communication terminal, the mobile communication terminal and the rendering agent are always synchronized, so the hyperlink function supported by the Internet browser running on the PC is supported.

FIG. When zoomed in, the process of displaying the entire image by enlarging the chunk images is illustrated. FIG. 9 shows a user assigning a priority to the chunk images most likely to be requested by the user next to the Internet page currently displayed on the screen in order to effectively provide a full browser function to the user. It shows a chunk image comparison scheduling method that downloads in advance when not in use and provides a service quickly to a user. 10 is a chunk for transmitting only the changed chunk image to the mobile terminal by comparing the image displayed on the screen of the mobile terminal with the image generated by the rendering agent in chunk image units in updating the chunk image at regular time intervals. A video transmission method is shown. FIG. 11 illustrates an updated chunk image determination method of determining whether or not to update a chunk image by comparing only a part of the chunk image in order to shorten a comparison time when comparing changes in the chunk image.

The Internet access device of the present invention initially transmits an authentication code to the terminal communication manager 310 included in the Internet browsing server through a wireless network, and the terminal communication manager renders when the transmitted authentication code matches the user terminal. Assign agent 320. The rendering agent is generated every time the mobile communication terminal accesses the Internet. When a plurality of mobile communication terminals simultaneously access the Internet, a plurality of rendering agents are generated. After the rendering agent is allocated 220, a navigator command is transmitted from the mobile communication terminal to the terminal communication manager. The navigation command includes URL information, and the terminal communication manager transmits the navigation command to the rendering agent. The rendering agent receives the navigator command and generates meta information including a screen image for receiving the Internet page corresponding to the URL through the wired internet network and transmitting the screen image to the mobile communication terminal and anchors present in the Internet page. . The rendering agent includes an internet browser and an HTML analyzer, and transmits the screen image and the meta information to the mobile communication terminal through the terminal communication manager, and the mobile communication terminal and the rendering agent continuously maintain the screen image and the meta information even after the initial transmission. To synchronize. The meta information includes coordinates of an anchor existing in an HTML document, a URL connected to the anchor, a title of an internet page, and a sub-nail image of a screen image. In addition, the control information is information on the change (cursor, focus, screen display direction, zoom in / out) of the mobile communication terminal in order to exactly match the screen displayed on the Internet browser included in the rendering agent with the screen displayed on the mobile communication terminal. And server changes (new window, window switch, mime opening other than HTML, window size change, error status), and the control information always has the same appearance as the Internet browser and mobile terminal included in the rendering agent. Synchronized to output. When the rendering agent transmits the screen image to the mobile communication terminal, the rendering agent is divided into chunk images (block-shaped small images) and transmitted. The rendering agent cuts the screen image into chunk image units when transmitting the screen image, and transmits the entire screen. The image may be transmitted periodically or the full screen image may be transmitted only once, and only the changed chunk image may be transmitted thereafter. In addition, the mobile communication terminal may transmit only the chunk image displayed in the screen window, or may change only the chunk image changed among the chunk images displayed in the mobile communication terminal. In order to calculate whether the chunk image has changed in the rendering agent, the past chunk image and the current chunk image are compared with each other. The sampling interval is variably applied according to the enlargement / reduction ratio of the chunk image output to the mobile communication terminal. In addition, the order of comparing the converted chunk images is determined based on the position of the cursor (hereinafter, 'phone cursor') of the mobile communication terminal as shown in FIG. 9, and first compares the chunk images located around the phone cursor, and then the mobile communication. Compare the remaining chunk images displayed on the terminal and compare the chunk images of areas not displayed on the screen of the mobile communication terminal. If a user moves or clicks the phone cursor in the middle of comparing multiple chunk images, the comparison order is reset from the beginning to determine whether the chunk image near the phone cursor has been updated. It has a feature that can be updated when it occurs. In addition, the size of the chunk image may be a single size of each chunk image, as shown in Figure 4, each chunk image may have a variable size, each chunk image is the same size but multiple chunk images It can also be bundled and processed as a single chunk image.

The mobile communication terminal reconstructs the chunk image to be transmitted and displays it on the screen of the mobile communication terminal, and changes the shape of the cursor when the cursor moves within the coordinate value of the hyperlink received from the rendering agent using meta information. In addition, when the user clicks the button of the mobile communication terminal in the hyperlink coordinate area, the mobile communication terminal transmits the clicked hyperlink coordinate value and the click event to the rendering agent by using the control information, and the rendering agent transmits the received hyperlink. The Internet page corresponding to the address of the hyperlink existing in the coordinate value is downloaded through the wired Internet network, converted into a chunk image, and transmitted to the mobile communication terminal through the terminal communication manager. When the user moves the Internet page currently displayed on the mobile terminal in one of up, down, left, and right directions, the mobile terminal transmits the screen movement event, the moving direction, and the size to the rendering agent by using the control information. The terminal generates a list of chunk images necessary for moving and reconfiguring the screen and transmits the chunk images to the mobile communication terminal through the terminal communication manager. When the user enlarges / reduces the size of the screen in the mobile terminal, when the screen can be reconstructed using the chunk image stored in the mobile terminal, the mobile terminal does not request an additional chunk image from the rendering agent. Each chunk image is enlarged / reduced and displayed on the screen, and when zooming in / out is required, if the chunk image is not stored in the mobile terminal, the mobile terminal transmits the chunk list required for the rendering agent, and the rendering agent corresponds to the corresponding chunk. The image is transmitted to the mobile communication terminal, and the mobile communication terminal enlarges / reduces the chunk image and displays it on the screen of the mobile communication terminal. In addition, the mobile communication terminal according to the present invention ranks the chunk images that have not yet been transmitted by the rendering agent based on the screen displayed on the current screen at the idle time when the user is not performing any action. Chunk image transmission scheduling method that can update the screen without spending time to receive the chunk necessary to reconstruct the screen when the user moves the screen in one of the up, down, left, and right directions because it is transmitted to the communication terminal in advance. Doing.

The above embodiment is only a preferred embodiment of the present invention, the technical spirit of the present invention can be changed or adjusted in various forms by those skilled in the art. If such change or adjustment uses the technical idea of the present invention, it is within the scope of the present invention.
