Apparatus and method for generating call information data for calls on long duration

摘要

An apparatus for generating data for long duration calls includes: call sensors distributed across a network for detecting call messages, correlating call messages relating to a call, and for storing call message related information, including at least one of the call network endpoints 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; and a call record controller for providing a control signal instructing at least some call sensors to determine whether any 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. The call sensors generate and transmit for storage an interim call data record (CDR) for each of the determined correlated call records.
