4 Overview p. 15
4.1 Service architecture p. 15
The Converged Charging Service or Offline Only Charging Service is provided by the CHF to the consumer and shown in the SBI representation model in Figure 4.1.1.
The ConvergedCharging Service (Nchf_OfflineOnlyCharging ) is part of the Nchf service-based interface exhibited by the Charging Function (CHF). The list of NF Service Consumer(s) is provided in Table 5.1-1.

4.2 Network functions p. 15
4.2.1 Charging Function (CHF) p. 15
The CHF is responsible for converged online charging and offline charging functionalities. The CHF provides the following:
- Quota;
- Re-authorisation triggers;
- Notification when Charging Domain determines rating conditions is affected or when CHF determines to terminate the charging service;
- Receiving service usage reports from NF Service Consumer; and
- CDRs generation.
4.2.2 NF Service Consumers p. 15
The NF Service Consumers shall support:
- Requesting and receiving the quota(s);
- Sending service usage reports; and
- Handling quota re-authorisation or abort notifications.
