Current
wireless access operational scenario is no longer based on a single
Radio Access Technology (RAT): 3G cells and WLAN hot spots are partially
overlapping the extensive coverage provided by 2G/2.5G systems. It is
then quite obvious to investigate how to optimally exploit the plurality
of RAT in order to efficiently use the radio resources guaranteeing at
the same time a good QoS level to users. This research area is usually
identified with the term CRRM Common Radio Resource Management. During
the last few years this problem has been widely investigated,
especially, from theoretical point of view. Nevertheless, some CRRM
aspects related to practical implementations and feasibility still need
further investigations, especially by taking into account procedures and
functionalities offered by standardization as well as, when possible,
techno-economic issues. Also the revisions of previous studies in the
light of new features made available in the latest release of the
standards could provide new interesting results.
