The signal of high station travels far away and overlaps adjacent station. Because LTE is made by same frequency

this means the same frequency interference and the decline of rate. But in reality

due to various reasons

lots of high stations have been built. It will bring huge cost if all these high stations are closed and rebuilt. This paper has provided the evaluation method of high station effect on TD-LTE network performance

combining with lots of driver test data to quantize high station effect on network performance. Then we have combined with the actual case to evaluate the high stations in the existing network

and according to the evaluation results to determine the handling methods. This method has improved the network performance

reduced the cost

and improved the optimization effi ciency.
