An offset measuring method according to the present invention accurately measures
a transmitting time offset of a base station. The offset measuring method for receiving
signals from the radio base station and measuring the transmitting time offset
of the radio base station includes the steps of calculating estimated values of
transmitting time offset based on signals received at a plurality of observation
points and selecting a minimum from the estimated offsets to determine the selected
minimum value as transmitting time offset of the radio base station.
