<p>In mobile IP networks, when a mobile node (MN) (151) moves from one cell to another, handover occurs. The result of the handover is that the MN (151) connects to the network through a new access router (AR) (123). The handover may occur between access routers of the same or different administrative domains. In all cases, the information related to the MN (151) has to be transferred from the old AR (101) to the new AR (123) in order to minimize the effect of the change of access routers.</p> |
