Question: In a 5G system, how can energy consumption for best-effort traffic (without QoS criteria) be managed without conflicting with performance policy principles?
Option 1: By defining policies that limit maximum energy consumption over time or by location, within the constraints of subscription policies.
Option 2: By guaranteeing a minimum Quality of Service (QoS) for all traffic types, thereby indirectly managing energy use.
Option 3: Through real-time pricing adjustments based on network-wide energy usage, incentivizing reduced consumption.
Option 4: By allocating fixed energy quotas to User Equipment (UE), regardless of service area or time.
Explanation: Best-effort traffic, by definition, does not have performance guarantees, allowing for the implementation of energy-limiting policies without compromising the principle that performance policies won't be traded off for energy efficiency. Policies can effectively cap maximum energy consumption either universally or with spatial constraints (e.g., specific service areas), aligning with subscription policy frameworks to manage energy use in 5G systems.
