REPORTING PERFORMANCE DATA AND CONTROLLING MOBILITY BETWEEN DIFFERENT RADIO ACCESS TECHNOLOGIES

A method and system for reporting performance and controlling mobility between multiple different radio access technologies are disclosed. According to one aspect, a controller in a network collects performance data concerning at least a first network operating according to a first radio access technology, RAT, and a second network operating according to a second RAT, the first RAT being different from the second RAT. The controller includes a performance monitoring collector, PMC, configured to collect performance data from at least a node of the first RAT and from at least a node of the second RAT. The collected performance monitoring data is analyzed to trigger selection of at least one serving radio cell for a user equipment, UE, connection based on the analysis.
