Abstract
A network management system (100) has a communications interface (110), a memory (104), and a controller (102). The controller is programmed to retrieve (202) a plurality of call detail records (CDRs), reconstruct (208) call paths from attributes in the plurality of CDRs, and generate (210) extended CDRs from reconstructed call paths.
Claims20
A network management system coupled to a communications network, comprising:
- a communications interface;
- a memory;
- and
- a controller programmed to:
- retrieve a plurality of call detail records (CDRs);
- reconstruct call paths from attributes in the plurality of CDRs;
- generate extended CDRs from reconstructed call paths;
- monitor patterns in the extended CDRs;
- and
- alert a service provider when an anomalous pattern is detected;
- wherein the anomalous pattern comprises at least one among a frequency of call transfers, a frequency of multi-trunk usage, a frequency of single-trunk usage, and a frequency of agent-to-agent communications at select call centers or a combination thereof.
A computer-readable storage medium, the storage medium being embedded with computer instructions for causing a computing device to perform the steps of:
- retrieving a plurality of call detail records (CDRs);
- reconstructing call paths from attributes in the plurality of CDRs;
- generating reformatted CDRs from reconstructed call paths;
- monitoring patterns in the extended CDRs;
- and
- alerting a service provider when an anomalous pattern is detected;
- wherein the anomalous pattern comprises at least one among a frequency of call transfers, a frequency of multi-trunk usage, a frequency of single-trunk usage, and a frequency of agent-to-agent communications at select call centers or a combination thereof.
A method, comprising the steps of:
- retrieving a plurality of call detail records (CDRs);
- retrieving caller identification numbers from the CDRs;
- reconstructing call paths according to the caller identification numbers;
- generating extended CDRs from the reconstructed call paths;
- monitoring patterns in the extended CDRs;
- and
- alerting a service provider when an anomalous pattern is detected.
