Network assurance analytic system

A method of detecting revenue leakage in a telecommunications system, the method comprising:

• monitoring telephony service detail records for calling line identities across point codes and routes of the telecommunications system;
• detecting characteristics of non-reconciled telephony service detail records of the monitored telephony service detail records of the telecommunications system;
• generating an absolute value, frequency and proportion for at least one of the detected characteristics;
• and
• generating a model score for the at least one of the detected characteristics, the model score based on the absolute value, frequency and proportion.

A system for scoring traffic of a telecommunications system, the method comprising:

• a network monitor for monitoring telephony service detail records for calling line identities across point codes and routes of the telecommunications system;
• a detector coupled with the network monitor for detecting characteristics of non-reconciled telephony service detail records of the monitored telephony service detail records of the telecommunications system;
• and
• a processor that generates an absolute value, frequency and proportion for at least one of the detected characteristics, the processor further generating a model score for the at least one of the detected characteristics, the model score based on the absolute value, frequency and proportion.
