Abstract: The present invention relates to technology that allows a user to interface more conveniently when executing a web browser in a mobile communication terminal mounted with a touch screen, using polygonal static icons and dynamic icons. A zoom icon, an other page view icon, a move icon, a favorite icon, and an others icon are displayed as basic menu icons on a side of a touch screen, and sub menus of the menu icon selected from the basic menu icons are displayed on the touch screen in a specified pattern so as to allow a user to easily execute a web browser. Also, polygonal context menus are displayed around a point touched by a user on a touch screen, and operation of deploying corresponding sub menus in several directions in response to a touch to a certain menu by a user is implemented.

Abstract: A target advertisement method in a mobile communication terminal includes a first step of, in a web browser, transmitting keywords having high probability indexes among previously stored keywords, to an advertisement server via the Internet in an initially driven state; a second step of, in the advertisement server, selecting advertisements appropriate for the keywords transmitted from the web browser and transmitting the selected advertisements to the web browser via the Internet; a third step of, in the web browser, displaying the advertisements transmitted from the advertisement server on a first screen of the web browser; and a fourth step of implementing an information searching function or a web surfing function in conformity with a user's desire.

Abstract: A web browser system includes a mobile communication terminal configured to implement decoding and parsing for HTML and CSS binary files, execute a JavaScript bytecode, decode an image file, and implement rendering for respective results, for web browsing of a web browser built therein; a proxy server configured to, in correspondence to a web address transmitted thereto, transmit a page access command to a web server of the corresponding web address via a wired network, implement grammar indentifying binary encoding for HTML and CSS transmitted from the web server to decrease capacity, convert quality for an image file to decrease capacity, compile JavaScript into a bytecode to decrease capacity, and transmit those files to the mobile communication terminal via a wireless network; and a web server configured to transmit files constituting a web page including the HTML, CSS, JavaScript and image files, to the proxy server.

Abstract: An advertisement linkage system of a mobile communication terminal, using a proxy server, includes a mobile communication terminal configured to be inputted with a web address from a user on a web browser built therein, transmit the web address to a proxy server via a wireless network, and display web contents and an advertisement received from the proxy server on a display; the proxy server configured to receive the web address from the terminal, transmit a web page access command to a web server via a wide bandwidth wired network, extract keywords from web contents received from the web server, transmit extracted keywords to an advertisement server, and transmit the web contents and an advertisement received from the advertisement server to the terminal; and the advertisement server configured to search an advertisement most appropriate for the keywords received from the proxy server, and transmit the advertisement to the proxy server.
