Question: In a 5G System (5GS), what is the primary mechanism for achieving Network Slice Performance and Analytics Charging?
Option 1: Real-time monitoring of User Equipment (UE) behavior without subscription to specific metrics.
Option 2: Subscription to specific performance metrics or analytics information of a designated network slice, reported to the Charging Function (CHF).
Option 3: Periodic audits of network resource allocation for post-service charging adjustments.
Option 4: Dynamic adjustment of Quality of Service (QoS) based on inferred user experience.
Explanation: This option correctly identifies the primary mechanism outlined in the context, emphasizing the importance of subscription to specific metrics or analytics of a network slice for charging purposes. This approach enables targeted and efficient billing based on the performance and analytics of a particular network slice, aligning with the principles of Network Slice Performance and Analytics Charging in 5GS.
