Abstract

A system and method for monitoring service quality using Call Detail Records (CDR) in a communications network, such as a Signaling System No. 7 (SS7) network, is disclosed. Network monitors capture substantially all signaling units in the SS7 network generate a complete record for all calls, transactions and other communications over the network. Users configure CDR profiles that are used to filter the records. A CDR application filters the records by parsing out signaling unit components that have been selected by the user in the CDR profile. The selected message components are then formatted into a CDR record, which is sent to an external system that generates certain statistics for the message records and stores the statistics to a database. A report application recalls the statistics from the database and presents statistics in a reporting format configured by the user. The reports indicate the statistical performance of network providers for selected called or calling telephone numbers or for selected services. The CDRs and statistics are available to a user either in real-time or in response to a query of historical CDR data. The network quality monitoring system is separate and independent from the network monitoring equipment.
