1. A method of selecting a target cell for handing off a subscriber unit in a cellular communication system, said system having a plurality of transceivers projecting cells upon the earth, said method comprising the steps of:

  • (a) procuring a list of at least one control channel for evaluation within said subscriber unit;

    (b) measuring a signal quality as received at said subscriber unit for one of said at least one control channel;

    (c) extracting a location data of said at least one control channel having sufficient signal quality;

    (d) retaining said location data for said at least one control channel in a group of candidate cells when said signal quality exceeds a signal quality threshold value;

    (e) repeating steps (b) thru (d) for each of said at least one control channel;

    (f) ordering said group Of candidate cells according to a range rate derived from said location data; and
