Zusammenfassung:PROBLEM TO BE SOLVED: To obtain a satisfactory reception or transmission characteristic by setting frequency deviation information except for the frequency deviation of the cell of a handover destination, when a difference between frequency deviation information of a cell in a present station and frequency deviation information of the cell of the handover destination is larger than a prescribed value. SOLUTION: At handover, frequency deviation information of the cell of a handover destination, which is held in a RAM in a CPU 4 and obtained by the scanning of the adjacent cell is transmitted to a limiter 5 from the CPU 4 at switching of a reception channel. The limiter 5 compares frequency deviation information of the cell of the handover destination with frequency deviation information of the cell, where the mobile communication equipment exists at present. When the difference between them does not exceed a threshold, frequency deviation information of the cell of the handover destination is set in a D/A converter 6, and information obtained by adding the thershold to the frequency deviation information of the present cell is set in the D/A converter 6, when it exceeds the threshold. Thus, a relative frequency deviation with the base station of the cell of the handover destination is corrected.
