This annex provides the information about the role of CAPIF in charging service API invocations. The common architecture for charging is illustrated in clause 4 of 3GPP TS 32.240 [6]. There are two charging mechanisms – offline charging and online charging. The role of CAPIF in both these charging mechanims is illustrated for informational purpose in this subclause.

The API invocations are subjected to charging (online, offline) as illustrated in figure C.1-1.

NOTE: As there are no impacts on CAPIF’s role in charging due to deployment of 3^rd party trust domain, it is not illustrated in the figures.
