DefinitionÂ
Charging Function (CHF) is defined using the Charging architecture and principles outlined by 3GPP TS32.240 (Ref 1) as the baseline. It is constructed as a set of capabilities to facilitate charging for telecom network connectivity services delivered by the CSP using 5G stand-alone networks (5GC), characterized by, and limited to:
- Interoperability with the 5G Service Based Architecture
- The ability to define and terminate the Nchf interface, via reference points N28 (SMF <-> CHF) and N40 (PCF <-> CHF)
- The ability to register as a CHF with the Network Repository Function (NRF) via the Nnrf API
- Interoperability with Charging Domain components
- Integration and call-flow orchestration between the CHF, Account Balance Management Function (ABMF), and Rating Function (RF) via a supported interface
- Interoperability with the Charging Gateway Function (CGF) via a supported interface, in order to facilitate CDR generation and data flow to downstream Billing Domain (BD) systems
