Abstract:

To solve suboptimal routing problem caused by network mobility basic support protocol, a novel route optimization solution is proposed which makes difference between handover inside and outside local mobility domain, modifies localized mobility management framework, extends prefix information option in router advertisement message and adopts corresponding address delegation and movement detection strategies. This solution can provide optimized routing, reduce signaling and latency and shorten tunnel length as well, especially when mobile network moves frequently.

Key words: mobile network, route optimization, localized mobility management, local mobility domain, local mobility anchor
