Abstract

A multi-step prediction method for mobile communication traffic, which relates to the field of mobile communication traffic prediction, which solves the low prediction accuracy of existing mobile communication traffic using autoregressive moving average series models and blindness in the process of using wavelet decomposition sex. Its specific implementation process is: using the results of Fourier spectral analysis as prior knowledge, guiding the decomposition process based on the maximum overlapping discrete wavelet transform, and extracting the detail items and trend items corresponding to the Fourier spectral components . In view of the increase of algorithm complexity brought by wavelet decomposition, the prior knowledge of Fourier spectrum is used to streamline and integrate the wavelet sub-layer, and the integrated trend item and period item are respectively predicted by the product seasonal summation autoregressive moving average model, Add up the predicted results to get the predicted value. The method of the invention is also applicable to the prediction of actual multi-period time series such as resident tap water flow, city bus flow, elevator passenger flow and network flow.

Description

technical field [0001] The invention relates to the field of mobile communication traffic prediction, in particular to an ARMA series model prediction algorithm and a priori knowledge-based maximum overlap discrete wavelet transform decomposition and integration algorithm. Background technique: [0002] Now the number of mobile communication users and the volume of traffic maintain a momentum of rapid growth. The long-term and stable operation of mobile networks depends on timely and effective network planning and optimization. When the mobile communication traffic exceeds a certain capacity, it is very easy to cause the switching system to be overloaded, causing network congestion, causing irreparable losses to mobile communication operators and users. Therefore, predicting the changing trend of mobile communication traffic based on traffic statistics and other business information can provide decision support for issues such as peak warning, base station configuration, and...
