A reliable mobile network management scheme based on PMIPv6

Now the challenge for the mobile network in reliability is more and more serious. The traditional mobile network management schemes such as Mobile IPv6 (MIPv6) and Proxy Mobile IPv6 (PMIPv6) have hardly taken this issue into account. In this paper, we make an improvement based on PMIPv6 to propose a network based reliable mobility management scheme called R-PMIPv6. The basic idea of R-PMIPv6 is to split the control and forward plane of traditional mobility anchor and increases the redundancy of forward plane to ensure the function continuity of entity and consistency of services, thus realize the reliable mobile network management effectively. We design the basic architecture and redundancy pool in which failure detection procedure and service switch procedure are detailed. Fault tolerant time and reliability of PMIPv6 are analyzed in mathematics. Finally numerical results are presented.
