Event Based Charging
In the case of event based charging, the network reports the usage or the service rendered where the service offering is
rendered in a single operation. It is reported using the ACR EVENT.
In this scenario, CTF asks the CDF to store event related charging data.
Session Based Charging
Session based charging is the process of reporting usage reports for a session and uses the START, INTERIM & STOP
accounting data. During a session, a network element may transmit multiple ACR Interims' depending on the
proceeding of the session.
In this scenario, CTF asks the CDF to store session related charging data.
