Seamless customer data move between source and target charging function elements of a communications system

Abstract

A charging system includes a source charging function element of a communications system. The source charging function element includes at least one processing circuit that is operative to process charge events for network charging related to a customer identifier to write customer data indicating the network charging into a source data partition of a global storage system. Based on receiving an event message, the source charging function element determines the customer identifier based on content of the event message and performs a look up in a translation function to obtain a mapping between the customer identifier and at least data partition that includes the source data partition. When the customer identifier is determined to be mapped by the translation function to the source data partition and to a target data partition, the source charging function element communicates with a target charging function element.
