Abstract: In view of the limitation that a single prediction model cannot accurately characterize the evolving law of wireless communication traffic，and considering its diversity，this paper presents a combined prediction with optimal weight for wireless communication traffic based on Self-Organizing Maps（SOM） neural network.This method firstly makes use of the SOM neural network to realize the automatic clustering of wireless communication traffic.Then for each class，the corresponding combined prediction with optimal weight is determined to provide the prediction values.The experimental results show that the proposed method not only can improve the prediction accuracy，but also enhance the prediction stability.
