Methods and systems for automatically and accurately generating call detail records for calls associated with ported subscribers

摘要

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.
