It is very important to find out abnormal calls and take effective control measures, but most of the current solutions are passive processing technology and lack active detection methods. Based on the existing telecom big data, through the statistical analysis of abnormal telephone behavior, the salient features which could represent the abnormal telephone were found. Then the the active detection method of abnormal telephone was designed based on the Ranking SVM sorting learning machine learning method. The experimental results on real datasets show that the proposed method can achieve higher accuracy under different sample sizes.
