Simultaneous Binding Extension to Proxy Mobile IPv6 as Service Enabler for Multi-Mode Mobile Devices

摘要

Various standardization development organizations consider network-based mobility management in future mobile communication networks to complement host-based mobility management. Proxy Mobile IPv6 is currently being standardized to suit basic requirements of network-based mobility management, such as no-host involvement in the location update procedure. In this paper, we want to motivate advanced operation of multi-mode mobile terminals, which attach to a Proxy Mobile IPv6 enabled network through multiple network interfaces simultaneously. We propose extensions to Proxy Mobile IPv6 enabled networks to allow simultaneous operation of a device's multiple interfaces, which have the same IPv6 address configured, while being registered with a single mobility anchor. Along with a description of these extensions, this paper comprises results of measurements we could perform in a real test-bed to show the performance gain of two target scenarios for flow distribution and bandwidth aggregation.
