Abstract
A system for proactive maintenance of a telecommunications network. A database is created containing characteristics of a plurality of valid logs. These valid logs represent alarms within a network which report status and abnormalities in the network and which have been specifically selected by a network domain expert or administrator from a larger group of logs. The characteristics correspond to a pattern of network fault parameters. The network is monitored for occurrences of a valid log. When a valid log is encountered, future occurrence of a fault is predicted based on an analysis of the valid log and the characteristics found in the database. Corrective measures are taken to prevent the fault from occurring.
