Abstract

There is provided a route optimization method in a mobile Internet Protocol (IP) system using a mobile Internet Protocol. When a mobile host (MH) moves over the Internet and is assigned to a care-of-address (CoA) corresponding to a changed point of attachment to the Internet, it sends a registration request message containing the care-of address to a home agent (HA) via a foreign agent (FA). The home agent stores the care-of address in relation to a domain name of the mobile host in an internal domain name server database. Upon receipt of a query about the mobile host by domain name from a correspondent node (CN), the home agent sends the care-of address corresponding to the domain name of the mobile host together with caching prevention information to the correspondent node. The caching prevention information is set to prevent the correspondent node or another domain name server from caching the care-of address of the mobile host. The correspondent node communicates with the mobile host using the care-of address.

Description

technical field [0001] The present invention relates generally to communication systems, and more particularly to mobile Internet Protocol (IP) systems and routing optimization methods therefor. Background technique [0002] The Internet today is a popular medium for many different types of multimedia information services. The Internet is a large group of interconnected computer networks, including commercial networks (.com), military networks (.mil), education-related networks (.edu), and other networks (eg, .org and .net). Generally, people utilize a World Wide Web (WWW) browser to access information and services available on the Internet. [0003] The increasing demand for multimedia services is motivating the widespread rollout of high-speed ATM-based networks for Wide Area Networks (WAN) and Local Area Networks (LAN) such as those used in schools and research institutes. Nevertheless, Internet services are still the most popular. [0004] Therefore, the Internet Engi...
