SYSTEM, METHOD AND APPARATUS FOR ROUTE-OPTIMIZED COMMUNICATION FOR A MOBILE NODE NESTED IN A MOBILE NETWORK

摘要

To overcome the routing sub-optimality problem arising in the heterogeneous protocol scenario where end-to-end route optimization protocol such as the Access Router Option protocol and Hierarchical Mobility Management protocol are implemented in the mobile hosts and mobile routers, this invention presents three methods. The first method is such that when visiting mobile node or mobile router wants to perform access router option based route optimization with some node, it will use its local care-of address as its care-of address. The second method is such that when visiting mobile node or mobile router decides to use hierarchical mobility management with some node, it will use regional care-of address as its care-of address. The third method is such that when there is legacy mobility anchor point in architecture, mobile router does not send the mobility anchor point option in its router advertisement.
