Definition 

Online Charging Function (OCF) 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 characterized by, and limited to:

  • Interoperability with the core network
    • The ability to interoperate with network elements via the Diameter Ro and Gy interfaces
  • Interoperability with Charging Domain components
    • Integration and call-flow orchestration between the OCF, 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
  • Commercial Models and purposes
    • Direct B2C connectivity 
    • Direct B2B connectivity
    • Telecom network inbound roaming
