LTE indoor distribution network is always difficult to monitor and analyze. This paper proposes a method which is based on characteristics of distribution for measurement report

makes use of multi-dimension performance data to conform the problem of the indoor distribution network. This approach is fast and comprehensively to diagnose the fault of LTE indoor distribution network

and it provides a guide and reference for optimization of LTE indoor cell. This method effectively improved the efficiency of problem finding. The accuracy rate of this method is 80% in the real networks.
