METHOD AND SYSTEM FOR HANDOFF BETWEEN AN ASYNCHRONOUS CDMA BASE STATION AND A SYNCHRONOUS CDMA BASE STATION

摘要

A method and system for enabling rapid acquisition of a forward link signal of a target base station in a mixed network of synchronous and asynchronous base stations is disclosed. The serving base station transmits an estimation timing error 417 between the serving base station and the target base station in the neighbor list. By using this timing information, the mobile station estimates the relative time offset 408 between the forward link signal received from the serving base station and the signals received from the target base station. The timing information obtained during handoff enables precise updating of the estimated timing error 417 transmitted sequentially to the neighbor list by the base station.
