<p>Processing of call data records is disclosed. Data packets captured from a monitored telecommunications network are obtained (202), decoded (206), and sessions are identified (208). The decoded data packets and the identified sessions are filtered (210) with a dynamic filter determining adjustable conditions for the protocol attributes and the session attributes such that the decoded data packets and the identified sessions fulfilling the adjustable conditions are kept in order to get attribute-filtered decoded data packets and attribute-filtered identified sessions. Dynamic call data records are generated (212) such that their structure and contents are determined dynamically on the basis of the attribute-filtered decoded data packets and the attribute-filtered identified sessions. The dynamic call data records are stored (214).</p> |
