Question: What is the primary purpose of Subscription-related Priority Mechanisms in the 5G QoS model?
Option 1: To prioritize flows based on subscription information, including RRC Connection Establishment and establishment of prioritized QoS Flows.
Option 2: To invoke the activation of prioritized QoS Flows through an interaction over Rx/N5 and packet detection in the UPF.
Option 3: To preserve differentiated treatment for prioritized QoS Flow and resource distribution prioritization.
Option 4: To provide instructions on how to perform pre-emption of media flows with the same priority assigned.
Explanation: Subscription-related Priority Mechanisms are used to prioritize flows based on subscription information, which includes the prioritization of RRC Connection Establishment and the establishment of prioritized QoS Flows. This allows for efficient management of network resources and ensures that high-priority services receive the necessary quality of service.
