Question: In a shared E-UTRAN/NG-RAN scenario, what information is a Hosting E-UTRAN/NG-RAN Operator required to collect for interoperator accounting with a Participating Operator?
Option 1: Only aggregated network resource usage across all Participating Operators.
Option 2: Network resource usage separately for each Participating Operator, including start and end of service events for their UEs.
Option 3: Detailed UE activity logs without differentiation by operator.
Option 4: General network performance metrics not specific to individual operators.
Explanation: To facilitate accurate interoperator accounting in a shared E-UTRAN/NG-RAN environment, the Hosting Operator must track and differentiate resource usage by each Participating Operator. This includes logging specific events like the start and end of service for UEs belonging to each Participating Operator, ensuring precise billing and accounting can be conducted between operators. This approach supports fair resource monetization and transparency in shared network infrastructures.
