Abstract:
1. A method for generating call detail records (CDRs) in a communications network environment that supports number portability, the method comprising: (a) passively copying a plurality of signaling messages relating to a plurality of different calls or transactions; (b) automatically correlating signaling messages that relate to the same call or transaction to produce a CDR usable by a plurality of different network data collection applications; (c) determining whether number portability processing is required for the CDR; (d) in response to determining that number portability processing is required for the CDR, querying a network number portability database using information contained in one of the received signaling messages; (e) incorporating information returned from the network number portability database into the CDR; and (f) delivering the CDR to a downstream system.
