PMIPv6 Multi-homing Support for Handovers across Heterogeneous Networks

摘要

It is getting common that a mobile terminal such as a smartphone has multiple interfaces with different access types and multi-homing is therefore becoming one of the essential mobile technologies. In this paper, we analyze the lack of multi-homing support in the Proxy Mobile IPv6 specification that has become the standardized mobility management protocol in 3 GPP and WiMAX Forum, and then propose a multi-homing support scheme based on multiple IPv6 address allocation to maintain application session continuity between two interfaces of a mobile node during an inter-technology handover. The proposed scheme is validated using QualNet simulator.
