Abstract

A method, information processing system, and wireless communication system for optimizing neighbor lists. A set of target communication sectors (240, 242) are identified within a given distance threshold from at least one of the base station (106) and a wireless device (134) currently registered with the base station (106). At least one target communication sector (240) is randomly selected from the set of communication sectors (240, 242). An identifier associated with the at least one randomly selected target communication sector (240) is inserted into a base station neighbor list (138). The base station neighbor list (138) is prioritized based on a set of call detail records associated with the at least one randomly selected target communication sector (240).

determining the at least one metric value based on at least one of;

a number of times that a wireless device selected the randomly selected target communication sector for hand-off procedure;

a success rate for attempted hand-offs into the randomly selected target communication sector;

a percentage of successful hand-offs per attempted hand-offs;
