Research and Application of Business Fault Diagnosis of IMS Network Based on Fault Tree and Knowledge Base
摘要
Abstract
With the gradual application of IMS technology in power communication network,regardless of the complexity of the core network equipment and access side devices or the mutual coupling is becoming more and more complex. Fault diagnosis ac?cording to a single device in the past has been unable to meet the demand,so real time monitoring of the running state of the equip?ment from the entire IMS business level is necessary,and this paper proposes a fault diagnosis method of the IMS service based on fault tree and knowledge base. The construction method of fault tree is put forward based on the characteristics of IMS service,and the process of fault diagnosis and treatment is obtained based on calculation of the minimum cut sets and the analysis of important de?gree of them. Combining with the fault knowledge base,fault tree implementation rules will be updated and the current fault will be given specific suggestion. The simulation results and the practical application results show that the method can locate the fault accu?rately and effectively,make the operation and maintenance personnel find and deal with it in time,so as to improve the reliability of the power communication network and the management level of communication operation and maintenance.关键词
