Override of distribution algorithms for an offline charging system

摘要

Systems and methods that override CDF distribution algorithms for offline charging. One embodiment comprises a distributor unit that connects to a plurality of Charging Data Functions (CDFs) of an offline charging system. The distributor unit receives a Diameter request from a Charging Trigger Function (CTF) for a Diameter session, and determines whether the Diameter request includes an override parameter indicating a destination CDF for the Diameter session. When the Diameter request includes the override parameter, the distributor unit sends the Diameter request to the destination CDF if the destination CDF is available. When the Diameter request does not include the override parameter, the distributor unit selects the destination CDF based on a distribution algorithm, inserts the override parameter in the Diameter request indicating the destination CDF, and sends the Diameter request to the destination CDF.
