ABSTRACT:
In an inter-station synchronization method establishing frame synchronization for a radio interval between radio base stations via a mobile station in a cellular mobile communication system constituted by a plurality of zones, a time alignment value corresponding to a mobile station which is in communication with a reference station is measured. An adjustment station receives a transmission signal from the mobile station which is in communication with the reference station, and a radio frame phase difference representing an offset between the received signal and a home intra-station radio frame synchronization signal is measured. A radio frame phase control value is obtained on the basis of a radio frame phase difference measured by the adjustment station and the time alignment value measured by the reference station. The phase of the radio frame synchronization signal of the adjustment station is adjusted in accordance with the obtained radio frame phase control value to be matched the phase with a phase of a radio frame synchronization signal in the reference station.
