Abstract:
1. An apparatus for generating call information data for calls of long duration occurring between an originating network endpoint and a destination network endpoint, the apparatus comprising: a plurality of call sensors distributed across a telecommunications network for detecting call messages, correlating call messages relating to the same call and for storing information, relating to those call messages, including at least one of the network endpoints for the call, in an at least partial correlated call record; a time detection module for determining which network endpoints are located in a time standard that has just passed, or is about to pass, a predetermined time; a call record controller for providing a control signal instructing at least some call sensors to determine whether any of the correlated call records relate to a call that includes one of the determined network endpoints and that started more than a predetermined time period prior to the predetermined time; wherein the call sensors generate an interim call data record (CDR) for each of the determined correlated call records and transmit the interim CDR for storage.
