This document describes a mechanism that enhances Mobile IP protocols to smoothly manage handovers for MNs equipped with multiple interfaces and moving across different links. For this purpose, the document provides precise indications on how to use the link layer events information to accelerate IP movement detection and optimize vertical inter-technology handovers. Experimentation results on vertical handovers between WLAN and GPRS networks are also given.
