The interference of mobile communication network optimization system is mainly for the intra system
inter system and short external interference.GPS interference in TD-LTE system has the characteristics of high interference intensity and concealment.If not combined with indicator statistics with field tests
other types of interference may be considered.This paper describes the types of interference that may occur in TD-LTE systems.On this basis
the characteristics of GPS interference and its impact on users are pointed out.At the same time
from the example of GPS interference in the process of monitoring the indicators and monitoring and analysis
as well as local base station GPS after the failure of monitoring methods and optimization analysis.
