A mobile radio station for use in a mobile radio network in which the number of monitored neighboring radio base stations can be reduced for power saving purposes without significantly degrading cell reselection performance. A reception field strength of a current cell and of signals transmitted from radio base stations neighboring the current cell is measured. If the reception field strength of a current cell is less than a first threshold that has been previously determined, a rate of decrease of reception field strength of the current cell is determined. If the rate of decrease exceeds a second threshold, the reception field strengths from a maximum number of radio base stations are measured. If the reception field strength of a current cell is over the first threshold and if the rate of decrease is under the second threshold, the reception field strengths of a reduced number of radio base stations are measured. <IMAGE> |
