A method and system that enables faster acquisition of the 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 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 subsequently transmitted in the neighbor lists by the base stations.

[ We claim:] [1.]1. A method for establishing a handoff of a wireless mobile station from a serving base station to an asynchronous target base station comprising the steps of:evaluating a timing error associated with the asynchronous target base station;estimating a search window for use in searching for an asynchronous pilot code based on said timing error; andsearching for the asynchronous pilot code within said search window.
