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

摘要

In a future scenario where end to end route optimization protocol such as the Access Router Option protocol and Hierarchical Mobility Management protocol are implemented in the visiting mobile nodes, mobile routers and the mobility anchor points, routing sub-optimality may occur when visiting mobile node that is nested is trying to communicate with the correspondent node. To overcome such routing sub-optimality arising in this heterogeneous protocol scenario, this invention presents a primary mechanism where the registration at the mobility anchor point is such that the local care-of address associated with visiting mobile node and local care-of addresses associated with upstream mobile routers of the visiting mobile node can be obtained using a single access router option protocol type of recursive tracing mechanism. Such tracing is achieved by embedding a different type of address in the access router option based binding registration at the mobility anchor point.
