Abstract: Methods and systems for generating accurate call detail records in networks that utilize number portability are disclosed. A number portability reconciliation (NPR) monitoring system receives signaling messages relating to different calls or transactions. The signaling messages may be copied from a network monitoring location upstream from where a number portability database lookup occurs for a call. The monitoring system automatically correlates messages relating to the same call or transaction into a call detail record usable by a plurality of different network monitoring applications. The NPR monitoring system determines whether number portability processing is required, and, in response, the NPR monitoring system queries a number portability database. The NPR monitoring system receives a response from the number portability database and updates the call detail record based on the response.

Abstract: Methods and systems for detecting and mitigating call routing arbitrage in a telecommunications network are disclosed. A network routing node, such as a signaling gateway (SG), intercepts call setup signaling messages. An arbitrage detector/processor examines parameters contained in an intercepted message to identify the presence of call routing arbitrage. For messages that indicate the presence of call routing arbitrage, the arbitrage detector/processor may perform a mitigating action, including redirecting the call to an interactive voice response (IVR) node, blocking the call, and/or inserting missing information in the call setup message and completing the call.

Abstract: Methods and systems for identifying calls connected without answer supervision and for automatically generating billing information for these calls are disclosed. A monitoring device copies signaling messages associated with calls. The signaling messages are correlated into call detail records. The call detail records are analyzed to identify calls connected without answer supervision. In one implementation, calls that exceed a predetermined duration and for which no answer message was returned from the terminating end office are identified as calls without answer supervision. For these calls, billing records may be generated and forwarded to a network billing center.

Abstract: A method and system for generating and providing existing and new message accounting records in a standard format using call data obtained from switching and/or signaling networks is disclosed. A system for providing augmented billing messages includes a message accounting record creation apparatus being in communication with a signaling network and a switching network. The message accounting record creation apparatus receives call records from the signaling network and message accounting records from the switching network and outputs augmented message accounting records. Each of the augmented message accounting records is generated using one of the signaling network call records and one of the switching network message accounting records.
