Abstract  Abstract

A method and system that enables faster acquisition of the forward link signal of a target base station in a mixed network of synchonous and asynchronous base stations is disclosed. The serving base station transmits in a neighbor list an estimated timing error (417) between the serving base station and a target base station. By utilizing the timing information a mobile station estimates the relative time offset (408) between forward link signals received from the serving base station and signals received from the target base station. Timing information acquired during handoff enables accurate updating of the estimated timing error (417) subsquently transmitted in the neighbor lists by the base stations.
