PPP Migration: A Technique for Low-Latency Handoff in CDMA2000 Network
17 July 2005
In this paper, we present a better approach to handling mobility than either of the above two techniques. The method is to migrate the PPP state from the old PDSN to the new PDSN transparent to the MN; once the PPP state migration is completed, the new PDSN will serve as the IP gateway to the MN. We have implemented the PPP migration technique and through experimental measurements show its benefits.
