Question: Which of the following 5G System (5GS) specifications defines Session Management, QoS Model, and QoS Policy Control relevant to Mission Critical service resource management?
Option 1: 3GPP TS 23.501, 3GPP TS 23.502, and 3GPP TS 23.503
Option 2: 3GPP TS 23.379, 3GPP TS 23.281, and 3GPP TS 23.282
Option 3: 3GPP TS 23.289 only
Option 4: None of the above specifications
Explanation: For Mission Critical services over a 5G System, understanding the broader system architecture and procedures is crucial for effective resource management. Specifically, Session Management, QoS Model, and QoS Policy Control are defined in specs related to System Architecture, Procedures, and Policy/Charging Control for the 5GS, making Option 1 correct as it encompasses these aspects necessary for managing resources efficiently in a 5G network to support mission-critical communications.
