This paper proposes a method based on the base station transmission bandwidth dynamic evaluation model and the base station data link layer indicators to realize the base station transmission bandwidth limitation problem identification. This method calculates the recommended bandwidth of the base station according to the actual service model of each base station

establishes a dynamic transmission bandwidth estimation model of the base station based on the busy time service mode of the base station

and directly extracts the data link layer indicators by using the FE/GE receiving maximum rate peak-to-average ratio as the identification standard. The method performs accurate identification of the problem of limited bandwidth transmission of the base station

can replace the verification method of the traditional stationby-site filling test

to realize the rapid identification and efficient discovery of the limited problem of the transmission bandwidth of the whole network base station

and greatly reduce the human and material resources and the time cost.
