name: CCF
full_form: Charging Collection Function
context: 5.1.2.2.3.1 CCF connection failure When the connection towards the primary CCF is broken, the process of sending accounting information should continue towards a secondary CCF (if such a CCF is configured). For further CCF connection failure functionality, see subclause "Transport Failure Detection" in IETF RFC 3588 [3]. If no CCF is reachable the network element may buffer the generated accounting data in non-volatile memory. Once the CCF connection is working again, all accounting messages stored in the buffer is sent to the CCF, in the order they were stored in the buffer. 5.1.2.2.3.2 No reply from CCF In case an IMS node does not receive an ACA in reply to an ACR, it may repeat the ACR message. The waiting time until a repetition is sent, and the maximum number of repetitions are both configurable by the operator. When the maximum number of repetitions is reached and still no ACA reply has been received, the IMS node executes the CCF connection failure procedure as specified above.
description: The Charging Collection Function (CCF) is responsible for collecting and processing charging information from various network elements. It ensures accurate and reliable data collection and processing for billing and charging purposes.
explanation: The description emphasizes the CCF's role in handling charging data within a network, its interaction with other network elements, and its impact on billing processes. These characteristics align with the definition of a Network Function.
