Abstract

A system and method of identifying sources of downlink interference among cells in a telecommunications network (10). Initially, call events (80) occuring in offending cells (72) are recorded. In conjunction, the disturbance events (78) occuring in a cell of the telecommunications network (10) are recorded. The recorded call events (80) with recorded disturbance events (82) are then correlated. At least one cell experiencing disturbance (78) on the downlink (134) is then identified. Next, the uplink disturbance source offending a cell is determined utilizing Call Event Recording (CER) (80) and Radio Disturbance Recording (RDR) (82) correlations. Finally, reciprocity is applied in order to identify downlink sources of interference within a cell causing disturbances (78) in other cells.
