A method and apparatus for minimizing the amount of time that a mobile station is to be out of communication with an “origination” base station while searching for a suitable system to which to perform a mobile station assisted hard handoff. After being directed to search for pilot signals in an alternate frequency band, the mobile station tunes to that alternate frequency and samples the incoming data, storing those samples in memory. When a sufficient number of samples have been stored, the mobile station retunes to the origination frequency. The forward link data is again received by the mobile station, and reverse link data can be successfully transmitted to the origination base station. After retuning to the origination frequency, a searcher in the mobile station will subsequently be employed to search for pilot signal offsets utilizing the stored data collected from the alternate frequency.
