ABSTRACT:
The invention relates to a method for avoiding interferences in cellular CDMA radio networks caused by defective mobile stations. To this end, the radio network is provided with a monitoring unit that compares an actual receive power arriving from a mobile station with a predetermined nominal receive power and initiates predetermined follow-up actions depending on the result of this comparison. Alternatively or additionally thereto, the monitoring unit is provided with at least one counter that is capable of detecting commands for power control of the mobile station that are transmitted individually for every mobile station from the base station to the mobile station and to initiate predetermined follow-up actions depending thereon.
