PBOP: A Design Methodology of Novel Network-based Mobility Management Architecture for Seamless Multimedia Services

PMIPv6 is a network-based mobility management protocol and plays roles for IP mobility management instead of the host. And the elements for IP mobility in a network are responsible for host mobility. This network basis is another approach to solve problems related with IP mobility. PMIPv6 can be seen as the extension of MIPv6 signaling and HA function because it performs mobility management for the mobile nodes connected to the network. However, since PMIPv6 conducts management for mobility as MAG takes MN’s roles, frequent MAG transfers between networks induce packet loss and delay handover time. This article suggests how to treat high-speed handover support among access routers located within the same domain using the IAPP (Inter Access Point Protocol) and also how to support prompt and effective handover using the reverse binding mechanism.
