Abstract: Aiming to the need of proactive monitoring and performance prediction in 3G networks, it proposes a prediction method of the Gaussian regression model based on the median filter, integrates the Gaussian regression model with the median filtering method, pretreats the sample data with median filtering, and then the processed data is done to the Gaussian regression prediction, the prediction results are as the prediction curve of the active alarm mechanism. Simulation results show that compared to other prediction algorithms, the Gaussian process based on median filtering predicts more effectively and generates more accurate prediction curves. It provides a theoretical basis for proactive monitoring in 3G and above network to determine an effective threshold.
