name: CDF
full_form: Charging Data Function
context: The Ga reference point supports interaction between a CDF and a CGF. The following information may flow across this reference point: - CDRs are sent from the CDF to the CGF; - Acknowledgements for these CDRs are returned from the CGF to the CDF. The protocol(s) crossing this reference point shall support the following capabilities: - Near real-time transactions; - Send one or more CDRs in a single request message; - Changeover to secondary destinations (alternate CGFs) in case of the primary CGF not being reachable; - Provide its own reliability mechanisms, e.g. retransmission of charging events, to run also on unreliable transport. This interface application is defined in TS 32.295[ Telecommunication management; Charging management; Charging Data Record (CDR) transfer ]  [54]. The content of the CDRs, and the CDR trigger conditions, are specific to the domain / subsystem / service and are detailed in the middle tier TSs.
description: The Charging Data Function (CDF) is a network function responsible for collecting and processing charging data records (CDRs) within the telecommunication network. It interacts with other network functions, such as the Charging Gateway Function (CGF), through reference points like Ga, to exchange CDRs and acknowledgments in near real-time transactions.
explanation: CDF is classified as a Network Function because it plays a crucial role in managing charging data records within the telecommunication network. It handles tasks such as sending CDRs to CGFs, receiving acknowledgments, and ensuring reliable transmission of charging events, aligning with the 3GPP's specifications for efficient charging management operations.
