An IP handoff process method and Internet service system are provided. In the IP handoff process method, a registration request message for multiple IP handoff is received from a mobile station having a plurality of Internet protocol (IP) addresses through a currently-moving mobile agent of the mobile station. Then, the registration request for multiple IP handoff is processed according to information included in the received registration request message. A reply message thereof is transmitted according to the result of updating the information to the mobile station through the currently-moving mobile agent. Then, the received registration request message is transmitted to a previous mobile agent of the mobile station before moving and a home agent of the mobile station as it is.

IP handoff process method and system for connection of internet protocols between mobile agents in heterogeneous network

Provided is an Internet protocol (IP) handoff method in a mobile agent platform (MAP). Accordingly, when an IP address of a mobile node (MN) is changed while the MN moves from an MAP to an adjacent MAP, the two MAPs generate border lists so as to share information on the MN, so that it is possible to perform a rapid IP handoff.
