A method for automatic evaluation of fault effects in the advanced intelligent network
H. Suzuki, Harumi Kawamura, Teruo Akiyama, Narumi Takahashi · 2002
The method described here provides network operators with criteria for deciding the priorities with which services degraded by network faults should be restored. This method consists of four processes: the first lists the unavailable services of customers affected by the fault, the second predicts the mean time needed to repair the fault, the third predicts the traffic trends for the affected services, and the fourth calculates the criteria used to decide the service restoration priorities. This method enables network operators to choose suitable means restoring services and to avoid future congestion due to faults. It also lets them respond more quickly and precisely to customer claims. We are introducing this method into our advanced IN operations systems.>
