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. If the handover pending record is not paired with an existing anchor record, then it is converted to an anchor record and a new call record is created to collect messages for the handover-to connection. All messages for a particular call on an MSC are correlated from each A interface in to a single call record. The A interface call record is then further correlated with other call and transaction records by a central server or processor.
