A Method to Support Multiple Interfaces Mobile Nodes in PMIPv6 Domain

摘要

In this paper, we propose a method to support handover between heterogeneous access technologies to multiple interface (MIF) mobile node (MN) in the Proxy Mobile IPv6 (PMIPv6) domain. PMIPv6 enables network-based mobility for a regular IPv6 mobile(MIPv6) with no mobility management protocol. But, there have been some issues identified with supporting a host with multiple interfaces attaching to the PMIPv6 domain. So we propose the method using NAT (Network Address Translation) in MAG (Mobile Access Gateway) which can continuously delivery packets although handover between heterogeneous access technologies occur. This paper analyzes the reduction of handover signaling cost in the proposed MAT (MAG Address Translation) method. It compares the handover signaling cost with PMIPv6 assisted by IEEE 802.21(MIH) and with the proposed method (i.e. PMIPv6-MAT) to show how much handover signaling cost reduction can be achieved.
