Abstract
A radio network controllerfor controlling a base station in a CDMA or W-CDMA mobile communication system includes a state measurement part, a call control processing part, and a frequency load distribution processing part. The frequency load distribution processing partis provided with a frequency state change processingfor updating each frequency's state dataand next assignment management databy referring a frequency state change notice notified when a state is changed by call control, and frequency assignment control processingfor selecting a frequency by referring to the updated next assignment management data and for returning a frequency assignment response, in response to a frequency assignment request transmitted from the call control processing part. With this constitution, load distribution of multiple frequencies is achieved by deriving a next assigned frequency on the basis of operating states of each frequency.
