Dynamic Distribution In An Offline Charging System

A distributor unit for an Offline Charging System (OFCS) of a telecommunications network, the distributor unit comprising:

• a memory for storing instructions and data and a processor configured to execute the instructions and process the data, wherein the one or more instructions, when executed by the processor, configure the processor to:
• distribute Diameter messages associated with a plurality of Diameter sessions to a plurality of Charging Data Function (CDF) units of the OFCS in accordance with distribution weights associated with each of the plurality of CDF units, such that Diameter messages associated with a same Diameter session are distributed to a same CDF unit;
• receive Diameter response messages from the plurality of CDF units in response to the distributed Diameter messages;
• calculate measured metrics for each the plurality of CDF units based on the distributed Diameter messages and the received Diameter response messages;
• and,
• adjust the distribution weights used for distributing Diameter messages for new Diameter sessions to the plurality of CDF units based on the measured metrics.
