Abstract: A method for enabling a first terminal of a packet-based network to communicate with a second terminal connected to a remote access server includes the steps of: registering the aliases and IP addresses of the first terminal and the remote access server in the gatekeeper; letting the first terminal to send a message to the gatekeeper for requesting a connection with the second terminal; causing the gatekeeper to request the remote access server to connect with the second terminal even when the second terminal is not registered with the gatekeeper; causing the remote access server to request the second terminal to register its alias and IP address in the gatekeeper; and, establishing communication between the first and second terminals through the gatekeeper.

Abstract: A method starts with submitting an internet protocol address to a web search engine so that the location of a user can be determined. Then, a user inputs one or more keywords that can be used by the web search engine to compare with all of its generated indexes. After searching various indexes, the web search engine may find multiple uniform resource locators that identify various servers that contain information that may be relevant to the user's search. Then, the web search engine uses an internet protocol mapping table, that is generated by the web search engine along with other data regarding various uniform resource locators prior to performing the requested search, to correlate the uniform resource locators with the geographical address of the server. Afterwards, the web search engine is able to sort the results of the search using the distance between the uniform resource locators and the user.

Abstract: A method for providing information placed in the specific location after analyzing the locations of the information is disclosed. Web search function to search information placed in the specific location comprises the steps of inputting the keywords and the locations of the desired information on the web browser by the web searcher, searching the indexes according to the keywords and the locations by the web search server, finding the URLs (Uniform Resource Locator) of the searched indexes by the web search server, comparing the URLs with the inputted locations, and transmitting the compared results to the web searcher. The present invention reduces the amount of the transmitting data, transmitting time, the amount of the data to be stored in the computer of the web searcher, and prevents the web searcher from sorting the searched pages case by case.
