1. A method of performing a hand-off of a mobile node into a foreign network, the method comprising:
- receiving, at an access point of the foreign network, identification information from a router serving the access point, the identification information including information of the router and unique access point information assigned to the access point;
receiving, at the access point, mobile node information about the mobile node entering the foreign network;
combining the mobile node information, with the identification information to generate a mobile Internet Protocol (IP) address for the mobile node; and
transmitting the mobile IP address to the mobile node.

Abstract
A method and apparatus for minimizing hand-off time using mobile node information. In the method of minimizing hand-off time using mobile node information, identification information is received that includes information about a router and unique information about an access point. Information about a mobile node connected to a network, which is controlled by the access point, is combined with the identification information, thus generating a mobile IP address of the mobile node. The mobile IP address is then transmitted to the mobile node.
