The objective of FMIPv6 is to reduce the amount of packet loss during the L3 handover. In spite of FMIPv6's objective, it could not always guarantee the successful fast handover if moving speed of mobile node is very fast. Since the L3 handover of MIPv6 is controlled by mobile node on a connectionless packet radio network, several messages should be exchanged among nodes to control handover process. And, handover process of FMIPv6 tightly depends on L2 triggering. These two features can derive possibility of failure because the trigger does not consider the state of mobile node's L3 and delivers triggers only based on variable wireless signal state. So, minimizing the L2 dependency of FMIPv6 should be accomplished for mobile nodes to provide guaranteed QoS to real-time services such as VoIP, IP-TV and video conferencing in fast moving environment. Most previous enhancement of L3 handover have been focused on how can make a reliable L3 anticipation. In this paper, we propose a new mode of FMIPv6 called adaptive early binding FMIPv6 that considers moving speed and L2 dependency. The proposed adaptive early binding FMIPv6 can provide QoS to real-time services by loosely depended L3 fast handover on L2 triggers and early binding update for mobile node's new COA when a mobile node moves very fast.
