Traditional Internet was originally designed for statically located terminals and can hardly meet the new requirements of wireless/mobile networks.This paper proposes a candidate for the mobility management scheme in future Internet

named Identifiers Separating and Mapping Scheme (ISMS)

discusses its basic theory and detailed approaches

and compares it with Mobile IPv6.ISMS is a network-based mobility management scheme which deploys location management and handover management inside of the network.It is also designed to satisfy the needs of faster handover

route optimism

scalability

controllability

location privacy

security and decreasing consumption on wireless links.Analysis shows that the average handoff delay of ISMS is far smaller than that of Mobile IPv6 and can satisfy most of the real-time applications.Experiments performed on a prototype show that ISMS is feasible and effective.
