MOBILE COMMUNICATION SYSTEM USING BASE STATION FREQUENCY CORRECTING METHOD

摘要

A mobile communication system equipped with a high-accuracy frequency base station device having a high-accuracy frequency oscillator and a low-accuracy frequency base station device which has a low-accuracy frequency oscillator, receives radio waves of a frequency of prescribed frequency accuracy transmitted from the high-accuracy frequency base station device, and performs transmission/reception of radio waves by controlling the frequency accuracy of the transmission/reception in accordance with the frequency accuracy of the radio waves from the high-accuracy frequency base station. A mobile station device of a mobile station may be provided in the mobile communication system. The mobile station device receives radio waves transmitted from the high-accuracy frequency base station device, controls the reference frequency which is the reference of the own transmission/reception in accordance with the frequency accuracy of the received radio waves from the high-accuracy frequency base station, and performs transmission/reception to/from a base station with the transmission/reception frequencies based on the controlled reference frequency. The low-accuracy frequency base receives radio waves transmitted from the mobile station device, controls the reference frequency which is the reference of the own transmission/reception frequency in accordance with the frequency accuracy of the received radio waves from the mobile station, and transmits radio waves to the mobile station device with the transmission/reception frequency based on the controlled reference frequency.
