Method of detecting damaged cellular telephone facilities

Abstract

A method for detecting inequality in path balance in a cellular telephone system including the steps of providing data describing measured signal strength of signals received at a mobile unit and at a cell site in the absence of interference at a plurality of points describing the entire system; providing data describing measured signal strength of signals transmitted from each cell and from the mobile unit in the cellular telephone system; accumulating and averaging the data describing measured signal strength of signals received at the mobile unit and at the cell site to eliminate path loss variances between points and the cell site; selecting data describing measured signal strength of signals received at a mobile unit with path loss variances eliminated, data describing measured signal strength of signals transmitted from the mobile unit, data describing measured signal strength of signals received at a cell with path loss variances eliminated, data describing signal strength of signals transmitted from each cell for each point of the system; utilizing the selected data for each point to provide measures of the difference between the strength of signals on each path between each point and each cell; comparing the difference on each path between a point and a cell to other differences between the point and the cell; and changing cell characteristics where a difference on any path between a point and a cell is significantly different than any other difference between the point and the cell.
