PPP Migration: A Technique for Low-Latency Handoff in CDMA2000 Networks
In current CDMA2000 standard, a Packet Data Serving Node (PDSN) acts as an IP gateway to the Internet. Mobile Nodes (MN) connect to a PDSN using a Point-to-Point (PPP) session and IP packets are tunneled over the PPP session from the client to the PDSN which then routes the packets onto a packet network. A CDMA2000 network is a hierarchical network where packets from an MN to the PDSN are transported over a Radio-Access Network (RAN). An MN could move from one RAN to another and still be anchored under the same PDSN; it is also possible that when an MN moves from one RAN to another, the anchor PDSN itself becomes different. In the latter case, there are two ways to handle mobility: (i) tear down the PPP session from the MN to the old PDSN and establish a new PPP session from the MN to the new PDSN, and (ii) use the fast-handoff mechanism as specified in the CDMA2000 standard where a P-P (PDSN to PDSN) tunnel is established to tunnel PPP frames from the old PDSN to the new PDSN and the...
