name: CPCN
full_form: Control Plane data transfer Charging Node (MME, SCEF, IWK-SCEF)
context: The following are high level charging requirements for Control Plane data transfer, derived from requirements in TS 23.682 [243]: - Every PDN connection shall be assigned a unique identity number for billing purposes. (i.e. the Charging Id); - CPCN shall be capable of identifying NIDD submission request events in mobile originated (MO) and mobile terminated (MT) direction; - CPCN shall be capable of identifying data volume per NIDD submission request; - CPCN shall be capable of handling the Charging Characteristics; - CPCN shall be able, based on operator configuration, to collect charging information for the PDN connection in the same PLMN using offline charging; - PDN connection in a different PLMN using offline charging. For the PDN connection, the CPCN shall collect the following information: - usage of the radio interface: the charging information shall describe the amount of data transmitted in MO and MT directions using Control Plane CIoT EPS Optimisation per each NIDD
description: The Control Plane Charging Node (CPCN) is a network function responsible for handling charging-related tasks in the control plane of the Evolved Packet Core (EPC) and 5G Core networks. It collects and processes charging information for PDN connections, including data volume, usage of radio interfaces, and other relevant details.
explanation: CPCN is classified as a Network Function based on its role in managing charging-related tasks within the network, as described in the context from 3GPP TS 32.253.
