A method and system are disclosed for identifying one or more sources of co-channel interference within a selected cell in a mobile telecommunications network. The system includes data collecting devices which measure and store interference levels within the selected sell and traffic levels within a plurality of candidate cells, any of which may potentially contribute to the interference. The system further includes a processing element which, for each candidate cell, determines a partial correlation coefficient between the stored interference levels and the stored traffic levels for the candidate cell. The processing element additionally determines the multiple correlation coefficient between the stored interference levels and the stored traffic levels for all of the candidate cells. Based upon the partial and multiple correlation coefficients, the processing element is capable of accurately identifying the candidate cells which contribute to the co-channel interference in the selected cell.
