**3. FHMIPV6/MPLS integration**

One of the major problems encountered in the integration HMIPv6/MPLS is the amount of signaling load in Binding Update (BU). Especially in case of a handover. At the time of BU can cause problems of safety and quality of services. With respect to security can be sent or received malicious messages, relative to the quality of services, excessive signaling load can significantly degrade the QoS metrics evaluated.

For this reason, we propose FHMIPv6/MPLS integration as a mechanism that will avoid both these problems. FHMIPv6 has a process of pre and post registration which keeps the communication between the mobile node and access router. FHMIPv6 has a process of pre and post registration which solves the problem observed in HMIPv6/MPLS integration. This we can say based on the work of R. Hsieh. FHMIPv6/MPLS integration has been made in the same manner as HMIPv6/MPLS integration. This integration allows us to compare which is better.

Is important mentioned, Fast Handover for Mobile IPv6 (FMIP) is a mobile IP extension that allows the MN to set up a new CoA before a change of network happens. This is possible because it anticipates the change of the router of access when an imminent change of point of access is detected. This anticipation is important because it minimises the latency during the handover, when the MN is not able to receive packets.

FHMIPv6 had been initially proposed by Robert Hsieh [hsieh03] as a way of integrating Fast Handover and HMIPv6 and shows why this integration is a better option than HMIPv6 alone.
