PROBLEM TO BE SOLVED: To provide a method of registering a mobile node on a home agent in a mobile IP environment and a mobile IP network system using the same. SOLUTION: The method of registering a mobile node on a home agent in a mobile IP environment includes: (a) collecting care-of-address information of foreign agents of subnets adjacent to a first subnet in which the mobile node currently resides; (b) broadcasting messages containing the collected care-of-address information when the mobile node moves from the first subnet to a second subnet adjacent to the first subnet; (c) in the foreign agent of the second subnet, receiving the broadcast messages and extracting the care-of-address information ; and (d) in the foreign agent of the second subnet, transmitting the extracted care-of-address information to a home agent of the mobile node to register the mobile node on the home agent if the extracted care-of-address information is identical to the care-of-address information allocated by the foreign agent.
