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.

Abstract: An example method can include receiving information identifying a quality of service (QoS) flow for a communication session involving a user equipment (UE). The information can include a QoS profile and a QoS flow identifier (QFI). The method can include identifying, from a QoS profile, a QoS configuration identifier associated with the QoS flow and selecting a data radio bearer (DRB) for the communications associated with the QoS flow. The DRB can be selected based on a mapping of a plurality of DRBs to a plurality of QoS flows, and the mapping can be based on corresponding QoS configuration identifiers of the plurality of QoS flows. The method can include assigning the QoS flow to the selected DRB by adding the QFI of the QoS flow to the mapping relative to the selected DRB and causing the communications associated with the QoS flow to be transmitted using the selected DRB.
