One Fault Diagnosis Method of Telecommunications Network

Abstract:

Telecommunications network fault location process of the root cause is the fault diagnosis process, there are mature products in general is the use of rule-based approach, rule-based approach is not suitable because of its inherent defects in the application of large-scale telecommunications networks, Thought about the uncertainty and incomplete of telecommunications networks events in nature, this article applied Bayesian network method to solve the information uncertainty and incomplete of telecommunications networks events, taking on the Bayesian reasoning method, proposed three optimization methods, namely, narrow range method, pretreatment method and the results of validation and verification method. with experiment on an actual existing network, these tree methods can effectively improve the telecommunications network fault diagnostic accuracy, lower false alarm rate.
