Patent ID: 8175607

Claim:
A method in a cell planning tool of determining the correctness of stored parameters associated with a cell site configuration, the method comprising the steps of: importing in-situ signal-strength measurements, SSmeasure, from measuring points located within the coverage area of the cell site; predicting the signal strength, SSpredict, at each of the measuring points utilizing the stored parameters associated with the cell site configuration; calculating the signal-strength difference between the imported in-situ signal-strength measurements and the corresponding predicted signal strength for each measuring point; and estimating a value indicating the correctness of the stored parameters based on the calculated signal-strength differences, wherein the estimating step includes the sub-steps of: dividing the coverage area into a selected number of segments; calculating a first average value, Δaver, for each segment separately, corresponding to the average of the calculated signal-strength differences of the segment; calculating a first standard deviation value, σ1, for each segment separately, corresponding to the standard deviation of said calculated signal-strength differences of the segment; calculating a second average value, σ1aver, corresponding to the average of said calculated first standard deviation values; and calculating a second standard deviation value, σ2, corresponding to the standard deviation of said calculated first standard deviation values.
