Charging and billing architecture for 5G network

Abstract

The charging and billing architecture for 5G and corresponding functions and interfaces supporting this new architecture have changed significantly and are now Service Based. There is now a converged charging interface covering online charging, offline charging and production of data records. This means that the interaction with the billing system now is though the Charging Function (CHF) in a converged charging system. The interface to the billing system has not changed, only been updated.
