  • Patent number: 7215748
    Abstract: Methods and systems for defining and distributing network data collection rule sets and for filtering messages using the rule sets are disclosed. Message-based filter criteria are automatically deduced from CDR-based filter criteria and downloaded to site collectors. The site collectors implement rule changes on-the-fly using a table-driven system. The message-based rule sets downloaded to the site collectors are supersets of the messages required by multiple different network monitoring applications. As a result, non-redundant, multi-application data streams are sent across the service provider's internal network, resulting in efficient bandwidth utilization.

  • Patent number: 7206394
    Abstract: Methods and systems for dynamic, rules-based peg counting are disclosed. According to one method, a user creates peg counter definitions using a rules-based language accessible via a graphical user interface. The peg counter definitions are downloaded from an administration server to network monitoring site collectors. The site collectors automatically detect the new peg counter definitions and begin using the new peg counter definitions without ceasing existing peg counting. Peg counter software on the site collectors periodically sends peg counter instances to a data gateway server. The data gateway server aggregates the peg counter instances generated by the various site collectors into system wide peg counter instances.

  • Patent number: 6765990
    Abstract: Database-driven methods and systems for database driven real time call tracing are disclosed. Signaling messages are copied from signaling link interface modules. The copied messages are sent to a database. A server located remotely from the database sends a query to the database for a real time call trace. The database is searched for messages that match the search criteria. If no messages are located in the historical data stored in the database, data entering the database is analyzed in real time.
