Spread spectrum communication system and handover method therein

摘要

A spread spectrum communication system comprises at least one mobile station (105) and a plurality of base stations (101, 103) for communicating with mobile stations in sites thereof by a spread spectrum scheme,
each of said base stations including: accumulation means for accumulating a reception timing difference indicating a difference in reception timing between a transmission signal from a mobile station in a base station in an adjacent site and a transmission signal from said mobile station in a self-station; and calculation means for obtaining a reception timing of the transmission signal from said mobile station in the self-station by using a reception timing difference between the self-station and a handover source base station in an adjacent site, which is accumulated in said accumulation means, when the self-station become a handover destination base station upon handover of said mobile station between adjacent sites.
