  1. PMIP Based DMM Approach Dapeng Liu (China Mobile) Jun Song (ZTE) WenLuo (ZTE) July. 2011

  2. Motivation • Current IP mobility approaches all rely on a central anchor point (HA，LMA)， which are considered as centralized mobility management approaches. • Limitations of centralized approached have already been studied by the team detailly • Researching and developing a DMM approach by using existent PMIP protocol with some extensions • http://datatracker.ietf.org/doc/draft-liu-dmm-pmip-based-approach

  3. Extensions • Local Mobility Anchor • Extended to support the query for the IP address of a MN’s MAG based on this MN’s HoA • Mobility Access Gateway • Extended to support the establishment of MAG to MAG tunnel for an optimized routing between MN and its CN • Extended to support the MN’s mobility when a MAG to MAG tunnel is enabled for this MN

  4. Data Deliver Approaches 2. Query (CN’s HoA) CN’sCoA LMA 3. Response (CN’s CoA) 4. Store CN’s HoA-CoA relation locally 5. Establish a tunnel MAG MAG MN’sCoA 1. Uplink Data (Src: MN’s HoA; Des: CN’s HoA) CN MN

  5. Handoff Approaches LMA 2. Update MN’s HoA-CoA relation MAG pMAG 1. downlink Data nMAG CN MN
