Abstract
Systems and methods described herein enable distribution of a Charging Function group identifier (“CHF-Group-ID”) and other CHF selection data to CHF consumers during Protocol Data Unit (PDU) session establishment in a 5G network. A Unified Data Repository (UDR) is provisioned with CHF-Group-ID details for each subscriber of the network. In one aspect, during PDU session establishment, CHF consumers obtain CHF-Group-ID information as part of a subscriber profile that is provided to all CHF consumers. No additional step or hop is needed for the CHF consumers to obtain the CHF-Group-ID. Thus, regionally segmented CHFs can be implemented without replication of data between CHFs in different regional segments and without additional signaling between network functions.
