Abstract

The availability of multiple technologies, with
micro and macro wireless cells, for network access combined
with terminals capable of exploiting such diversity in wireless
access requires the development of new mechanisms for
optimized handover procedures. Appealing solutions should
support network controlled handovers through heterogeneous
technologies, preferably combined with a cross-layers two/three
design. The IEEE 802.21 working group is currently
standardizing the methods and the protocol potentially able to
provide such a solution. In this paper we analyze the impact of
signaling timing on network controlled handovers execution and
performance in this environment. Through an extensive
simulation study, we obtain results, that can be exploited in both
terminal and handover procedure designs.
