Cellular mobile radio system

摘要

In a method of selecting one of a number of dedicated control channels which are transmitted from a number of base stations (B1 -B21) where the mobile station has an equalizer to compensate for the multipath propagation characteristics of the radio medium between the mobile station and a certain base station, the signal quality of the dedicated channel (DCCH1) which has the greatest signal strength is measured without the equalizer. If the signal quality is not acceptable, a new detection is made with the use of the equalizer. If the signal quality then is acceptable another detection is made without equalizer on the dedicated control channel which has the next strongest signal and if this detection revealed an acceptable signal quality the base station (B2) transmitting this control channel is selected by the mobile station for the futher call progress. Power consumption by the equalizer is thereby reduced.
