Abstract
Method for improving hand-off performance in a code-division multiple access (CDMA) cellular telephone system. A preferred embodiment comprises the analysis of saved hand-off information to minimize the size of neighbor lists for each base station in the cellular telephone system. If a requested base station (for example, base station 618) is listed in any neighbor list of any base station (for example, base stations 605, 617, and 620) involved in the hand-off, then the requested base station is not added to any neighbor list. If the requested base station is not the neighbor lists of any of the base stations involved in the hand-off, then it is added to an initial base station's neighbor list (base station 605).
