Question: In a Multi-Operator Core Network (MOCN) scenario, what is provided by the gNB-CU-CP to facilitate resource sharing among involved gNB-DUs and gNB-CU-UP for broadcast MBS sessions?
Option 1: A list of dedicated F1-U resources for each PLMN
Option 2: Information to identify broadcast MBS sessions for shared RAN resource utilization
Option 3: Configuration for separate multicast services per PLMN
Option 4: gNB-DU capability updates for dynamic resource allocation
Explanation: In the context of MOCN, efficient use of resources is crucial. The gNB-CU-CP plays a key role in optimizing resource utilization by identifying which broadcast Multicast/Broadcast Services (MBS) sessions can share RAN resources among multiple gNB-DUs and the gNB-CU-UP. This approach ensures resource efficiency without compromising service delivery across different Public Land Mobile Networks (PLMNs). Option 2 correctly highlights the provision of specific information by the gNB-CU-CP to enable this shared resource utilization for broadcast MBS sessions.
