context: QoS update charging message flow in PEC charging. Figure 5.2.4.2.8.5-1: Charging for update of Session with QoS - PEC 1) The EAS sends the Session with QoS update request to the EES. 2) The EES updates data session with specific QoS with 3GPP 5G Core Network. 3) The EES sends Session with QoS update response to the EAS: 3ch-a) Charging Data Request [Event]: The EES generates charging data related to Session with QoS update and sends the charging data request for the CHF to process the related charging data for CDR generation purpose. 3ch-b) Create CDR: The CHF stores received information and creates a CDR related to the event. 3ch-c) Charging Data Response [Event]: The CHF informs the EES on the result of the request. 5.2.4.2.8.6 Session with QoS notification charging - PEC Figure 5.2.4.2.8.6-1 describes a Session with QoS notification charging message flow in PEC charging. Figure 5.2.4.2.8.6-1: Charging for Session with QoS notification - PEC 1) The EES detects User Plane event for
description: Post Event Charging (PEC) is a procedure in the 3GPP charging architecture that involves generating and processing charging data after a specific event has occurred, such as a QoS update or a user plane event. This procedure is used to create Charging Data Records (CDRs) for billing purposes.
explanation: The context describes PEC as a process involving multiple steps, including sending charging data requests, creating CDRs, and responding with the result of the request. This indicates that PEC is a sequence of operations or a procedure, which justifies its classification as a Procedure.
