Designing Improved Traffic Control in Network-based Seamless Mobility Management for Wireless LAN

Authors:
Takeshi Usui

Keywords: Network-based seamless mobility management; Wireless LAN; QoS; VoIP

Abstract:
Seamless mobility management which prevents packet loss when mobile terminals (MTs) move is an indispensable feature for future mobile networks. Proxy Fast Mobile IPv6 (PFMIPv6) has been standardized to reduce packet loss of user data in network-based mobility management. By predicting the movement of MTs, it can minimize packet loss by forwarding user data from the previous mobile access gateway (MAG) to the new MAG where MT makes a handoff, and by buffering the forwarded data at the new MAG until the MT is attached to it. When shared wireless access technology (e.g., wireless LAN) is employed as a wireless access network, the released packets from the buffer in the new MAG degrade the communication quality of the other (resident) MTs already attached to the wireless access network. In this paper, we propose a MAG design treating the buffered packets to prevent degradation of the communication quality of all MTs (resident MTs and MTs making handoffs). Using a packet-based simulation, we investigate the communication quality and show the proposed method’s validity.
