Question: In a 5G System (5GS), what triggers the generation of a Charging Data Function (CHF) Call Detail Record (CDR) for Network Slice-Specific Authentication and Authorization charging?
Option 1: Expiration of a predefined time interval since the last CDR was generated
Option 2: Completion of a User Equipment (UE) session, regardless of the network slice
Option 3: Receipt of a specific number of chargeable events from any network function
Option 4: Receipt of a Charging Data Request [Event] by the Charging Data Function (CHF)
Explanation: In the context of Network Slice-Specific Authentication and Authorization charging in a 5GS, the generation of a CHF CDR is directly triggered by the receipt of a Charging Data Request [Event] by the CHF. This ensures that charging information for specific events is accurately captured and recorded, highlighting the importance of event-driven charging management in 5G networks.
