SYSTEM AND METHOD FOR PROVIDING HANDOVER OF A MOBILE IP TERMINAL IN A WIRELESS NETWORK

摘要

Disclosed is a system for providing handover of a mobile node in a wireless network supporting Mobile IP. The mobile node sends, when handover is needed , a request for neighbor access router information to a first access router currently communicating with the mobile node, and selects, if the neighbor access router information is received, a second access router serving as a target access router using the received neighbor access router information. The first access router exchanges access router information with a neighbor access router, provides neighbor access router information to the mobile nod e upon receiving the neighbor access router information request from the mobil e node, and redirects data to be delivered to the mobile node to the second access router to which the mobile node will be handed over. The second acces s router forwards data to be delivered to the mobile node to the corresponding mobile node.
