Method and system to optimize capacity of a CDMA cellular communication system

Abstract

A method and system for optimizing system capacity and allocation in a CDMA cellular communication system obtains a current call volume and associated call characteristics for each of a plurality of cell sites in the system, and estimates effective boundaries for each of the plurality of cell sites to minimize the weighted sum of powers received at selected base stations. Selection of base stations can include highly loaded sites and adjoining cell sites. System parameters are then controlled to effect the estimated cell site boundaries. Thus, the present invention allows for dynamic shrinking and enlarging of cell boundaries to enhance the system capacity advantages of CDMA while maintaining contiguous coverage and avoiding coverage holes.
