  • Methods and systems for automated analysis of signaling link utilization
    Patent number: 7301910
    Abstract: Methods and systems for automated analysis of signaling link utilization are disclosed. A method for automatically analyzing signaling link utilization includes displaying signaling link utilization data to a user via a computer display device. User input regarding a portion of the link utilization data that the user desires to analyze is received. Signaling message data corresponding to the selected link utilization data is automatically extracted from a database. The signaling message data may be used to determine the cause of signaling link utilization problems.

  • Database driven methods and systems for real time call tracing
    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.

  • Methods and systems for collecting and processing signaling system 7 (SS7) message signal units (MSUs)
    Patent number: 6327350
    Abstract: A system for collecting and processing SS7 message signaling units (MSUs) includes a network interface for copying MSUs from an SS7 signaling link or a TCP/IP signaling link. A call detail record generator communicates with the link interface to receive the copied MSUs and parse the MSUs to extract desired parameters from the MSUs. An application interface kit received commands from an application to control the flow of MSU parameters to the application in real time.
