Fault judgment method and device

Abstract

The embodiment of the invention provides a fault judgment method and device. The method comprises the following steps: acquiring current transmission parameters of a target cell, wherein the transmission parameters comprise transmission round trip time RTT time delay and a transmission control protocol TCP retransmission rate; obtaining a preset judgment model corresponding to the geographical location information according to the geographical location information of the target cell; wherein the preset judgment model comprises RTT time delay and a corresponding relationship between a TCP retransmission rate and a fault type, and the fault type comprises a wireless fault and a non-wireless fault; and determining the fault type of the target cell according to the transmission parameters andthe preset judgment model. According to the embodiment of the invention, the fault type in the end-to-end problem is quickly judged only through the wireless RTT time delay, the TCP retransmission rate and the preset judgment model, the processing efficiency of the end-to-end problem in network optimization work is improved, and the difficulty of network optimization personnel in end-to-end problem troubleshooting work is reduced.
