Abstract:
A method for monitoring the service quality in a communications network, wherein a communication monitoring system generates communication detail records for communications on said network, the method comprising the steps of:capturing, at monitoring units, messages from one or more communication links in the communication network, wherein each message corresponds to a specific one of a plurality of calls or transactions, and wherein a plurality of messages are associated with each of said calls or transactions; identifying a first-detected message for a particular call or transaction; designating a monitoring unit that detected said first-detected message as an anchor monitor for the particular call or transaction; forwarding any other messages associated with the particular call or transaction to the anchor monitor; correlating, at the anchor monitor, all of the messages associated with the particular call or transaction into a call detail record for the particular call or transaction, wherein the call detail record comprises all of the messages associated with the particular call or transaction that have been captured by all monitors from all links in the communications network; transmitting said call detail records directly from said anchor monitor to a quality of service application; filtering said call detail records to generate a historical report of service quality on said network, wherein said call detail records are filtered according to a user configured profile to generate said historical reports; and filtering said call detail records as they are received to generate real-time service quality reports.
