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.

Method for avoiding interferences in cellular CDMA radio networks caused by defective mobile stations

Switching network for high-frequency signals

A mobile repeater for relaying radio signals between mobile stations and base station of a digital cellular radio network as the repeater moves from cell to cell. The mobile repeater includes a downlink branch for receiving from the base station and retransmitting to the mobile stations, an uplink branch for receiving from the mobile stations and retransmitting to the base stations, and an intelligent control unit for supporting the transition of the relay connection as the repeater moves from one cell to an adjacent cell. The intelligent control unit measures the repeater receiving field intensity of base station radio signals, monitors signalizing traffic, controls the signal output level to force transition to a new base station, and tunes the repeater frequency channels to those used by the new base station.
