name: CHF
full_form: Charging Function
context: The 5G data connectivity charging solution includes the applicable options in converged charging architecture: Figure 5.6.4.1-1 It also defines the following functionalities: - Flow Based Charging (FBC) based on PCC Rules, and associated triggers in SMF for interaction with CHF. - Qos Flow Based Charging (for roaming QBC) based on associated triggers in SMF for interaction with CHF. - CHF capability to enable/disable SMF triggers. - CHF CDR generation mechanisms for FBC and roaming QBC. - Charging information specific to 5G data connectivity (for PDU session FBC and roaming QBC) are specified on top of generic charging information for: - Converged charging behavior across Nchf - CHF CDRs content.

description: The Charging Function (CHF) is a network component responsible for managing and processing charging information in the 5G system architecture. It interacts with other network functions, such as the Session Management Function (SMF), to enable flow-based charging, QoS flow-based charging, and converged charging behavior.
explanation: The context explicitly mentions CHF as a functional entity within the 5G system architecture, highlighting its role in charging and billing processes. This classification is justified by the description of CHF's interactions with other network functions and its capabilities in generating charging data records (CDRs) and enabling/disabling SMF triggers.
