  • Patent number: 8254939
    Abstract: System and method for combining call records for different protocols into a single combined call record during a call. An embodiment comprises correlating messages having multiple protocol formats, comprising correlating messages complying with a first protocol into a first call record using a first correlation key, correlating messages complying with a second protocol into a second call record using a second correlation key, detecting a key message complying with the first protocol, the key message having a fetch key parameter associated with messages complying with the second protocol, combining data from the second call record into the first call record to create a combined call record, and creating a pointer linking the second call record to the first call record.

  • Patent number: 6633555
    Abstract: A system and method for correlating messages from A interface links is disclosed. When an initial connection message for a new call connection is detected, a new anchor record and call record are created to capture messages for that call. When an initial handover connection is detected, a handover pending record is created to collect messages related to the handover connection. When either a handover-from or handover-to connection is detected, a handover connection reference record is sent to a rendezvous processor. Handover-to and handover-from connection reference records are correlated in the rendezvous processor by matching data keyed to the specific handover event. Once a handover pending record is paired to an existing anchor record, the handover pending record is converted to a routing record to route messages to the anchor record.
