Abstract:
A method for evaluating the effect of channel reassignment and/or a change in parameter settings on the interference quality in a cellular system, wherein said cellular system being evaluated may be an entire cellular system or a portion of a cellular system, comprising the steps of:identifying a plurality of likely servers for a plurality of corresponding known positions in a cellular telephone system; comparing additional signals received at said plurality of known positions in said cellular telephone system to determine the potential interference of each of said additional signals with said plurality of likely servers; and determining a quality value for each of said likely servers at each of said corresponding known positions, based upon the interactive probability of interference from said additional signals, for a first set of planned channel assignments and parameter settings; dividing said cellular system into a plurality of sectors, each of said sectors including a plurality of said known positions; determining an interference quality value for each of said sectors based upon the quality values for the known positions within each of said sectors; determining a first quality score for said cellular system based upon said interference quality values for said sectors of said cellular system; determining the effect on said potential interference from one or more of said additional signals which would occur as a result of changing one or more parameters and/or channel assignments of one or more of said additional signals; redetermining said quality values for each of said known positions effected by said change in said additional signals; redetermining said sector interference quality values for each sector effected by said redetermination of said quality vales for said each of said known positions; determining a second cellular system interference quality score based upon said redetermined sector interference quality values; and evaluating the system interference score quality effect of said changes by comparison of said first system interference quality score with said second system interference quality score.
