Abstract:
1. An apparatus comprising: a distributor unit configured to connect to a plurality of Charging Data Functions (CDFs) of an offline charging system; the distributor unit comprising a processor configured to receive a Diameter request from a Charging Trigger Function (CTF) for a Diameter session, and to determine 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 is configured to send 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 is configured to select the destination CDF based on a distribution algorithm, to insert the override parameter in the Diameter request indicating the destination CDF, and to send the Diameter request to the destination CDF.
