Geometric Recognitions Models of Fault Characteristics in Mobile Core Network

This article main researches the methods for recognizing fault points in mobile core network. In the light of the abnormal phenomena of the network systems that the TRAU data suddenly decline to zero due to the reasons of the network faults, it defines the data down burst event. And aiming at the class of the data down burst event, it defines doubted fault point and alerted type of fault points respectively. It also proposes two criterions of the sufficient and necessary conditions in order to identifying the doubted fault point and the alerted type of fault point respectively. Meanwhile, it gives the strict proofs in Mathematics.
