Abstract When it is determined that the hand-over is necessary, a pilot strength measurement message is generated and transmitted to a base station BSa, under the hand-over request control. Arrival of an acknowledgement response from the base station BSa is monitored. If the acknowledgement response is not sent back before a timer times out, the receiving strength of a pilot channel PNa2 in the established synchronization and the receiving strengths of pilot channels PNb1 to PNb3 and PNc1 to PNc3 from neighboring base stations BSb, BSc and remaining base stations are re-measured, and the pilot strength measurement message including the latest measurement values obtained from the re-measurement is retransmitted to the base station BSa.
