Question: In a 5G System (5GS), what is the primary purpose of the Allocation Retention Priority (ARP) QoS parameter for each QoS flow?
Option 1: To dynamically assign standardized 5QI values for QoS characteristics
Option 2: To determine the packet's routing path through the network
Option 3: To set the maximum bandwidth allocation per user equipment (UE)
Option 4: To define the priority level, pre-emption capability, and pre-emption vulnerability of a QoS flow in resource limitation scenarios
Explanation: In the context of 5G QoS management, ARP plays a crucial role in managing resources efficiently, especially during scarcity. By defining the priority level, pre-emption capability (ability to preempt another flow), and pre-emption vulnerability (susceptibility to being preempted by another flow) of each QoS flow, ARP helps the network decide whether to accept or reject new QoS flow requests based on resource availability, ensuring optimal allocation and minimizing disruptions to critical services.
