Question: How does a network achieve Network Slice usage control for supporting UEs?
Option 1: By configuring UE-controlled Slice Usage Policy.
Option 2: By implementing dynamic PDU Session establishment and modification.
Option 3: By using only Network Slice deregistration inactivity timers.
Option 4: By configuring network-controlled Slice Usage Policy, PDU Sessions inactivity timers, and Network Slice deregistration inactivity timers.
Explanation: According to the specified method for achieving Network Slice usage control, a network must configure both network-controlled Slice Usage Policy and specific timers (PDU Sessions inactivity timers and Network Slice deregistration inactivity timers) to effectively manage and control UE access to network slices.
