A dynamic identification method and its device for normal fluctuation range of performance normal value

Abstract

The invention discloses a dynamic confirming method for performance index value normal fluctuating range, comprising following steps: obtaining a historical value of the network performance index, and dynamically obtaining the latest historical sample data; processing pre-treatment to obtain a normal sample data; processing phase space re-construction to obtain a training sample data; processing training modeling to take residual error white noise as condition of selecting the optimal supporting vector machine model; using the optimal supporting vector machine model to predict the data on the to-be predicted time point, and calculating the confidence interval of the predicted value to obtain the performance index value normal fluctuating range; detecting whether the optimal supporting vector machine model is suitable for the next prediction of the to-be predicted time point; if the model is not suitable, processing re-training. The invention also discloses a device for the dynamic confirmation performance index value normal fluctuating range. The invention significantly enhances the precision of the performance dynamic early warning, and reduces wrong report and missing report of the performance warning.

Description

technical field [0001] The invention relates to the field of telecommunication network management, in particular to a method for real-time monitoring of telecommunication network performance, and in particular to the prediction of the fluctuation range of the telecommunication network performance index. Background technique [0002] With the increasingly fierce competition in the communication market, major telecom operators have successively proposed strategic transformation. Traditionally, the operation and maintenance management operated by the support department of the telecom operator has always belonged to the background part of the business process, directly oriented to the management of the network and equipment, and has no direct relationship with the market and customers. With the increasingly fierce market competition, improving customer satisfaction with network services has gradually become an important aspect for telecom operators to enhance market competitiven...
