The authors exploit a Fast RAT switch solution to improve QoS
metrics of the system by means of efficient RAT
scheduling. Analyses presented here show
a better understanding concerning which system
measurements are most efficient in a mutliple-RAT
scenario. More specifically, they present an analysis
concerning the metrics that should be used as
RAT scheduling criteria and how frequent these
switching evaluations should be done
