Question: In a Shared GERAN or UTRAN setup, as per dynamic capacity negotiation principles, what is a key characteristic of how spare on-demand capacity can be allocated by the Hosting RAN Operator to a Participating Operator?
Option 1: Exclusively through manual intervention based on predefined static policies.
Option 2: Based on real-time traffic demand but only after approval from regulatory bodies.
Option 3: Through a bidding process among all Participating Operators.
Option 4: Automatically, based on agreed policies and without human intervention.
Explanation: This correct answer reflects the automation and policy-driven nature of dynamic capacity negotiation in shared RAN environments. The ability to allocate spare capacity automatically (without human intervention) based on predefined policies is crucial for efficient and rapid response to changing network demands, aligning with the principles outlined for dynamic capacity management in shared radio access networks.
