超高站覆盖范围广，对周边基站形成广泛的重叠覆盖，对于同频组网的TD-LTE网络，意味着同频干扰、速率下降。但是在实际建网过程中，由于种种原因已建成了大量超高站，如果将已建成的超高站全部关闭，重新选址建站，则会带来巨大的成本。提出了一种评估超高站对网络性能影响的方法，基于路测数据，量化一个超高站对网络性能的影响程度，并结合实际案例对现网中的超高站进行了评估，根据评估结果来决定对超高站的处理方式，不仅改善了网络性能，而且降低了建网成本，提高优化效率。

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.
