| Abstract | |
The present work is focused in the area of fault detection in communications systems using billing tickets archives as base of information. In most of the cases, these archives are used by the telecommunication carriers only for billing purposes. The thesis presents algorithms for fault detection and consequence alarms generation. The algorithms are analyzed and classified according to their performance. The main objective of the fault detection with a bigger efficiency is to diminish the deficiencies in system¿s QoS, reducing economic losses and improving customers satisfaction. Market indicators show that from 3% to 15% of Telecommunication companies gains are lost for system failures. The algorithms search efficient ways to detect faults in the elements of a communication system (AU) | |
