Question: What is the primary reason for using a 5G bearer for application-level control signaling in Mission Critical (MC) services, beyond resource efficiency?
Option 1: To support low-latency communication for individual MC service clients
Option 2: To improve MC service performance (KPIs) and handle high load scenarios
Option 3: To enable broadcast and multicast capabilities for media sessions only
Option 4: To reduce the Quality of Service (QoS) requirements for control signaling
Explanation: In MC services, reliable and efficient control signaling is crucial. Using a 5G bearer for application-level control signaling beyond mere resource efficiency is primarily aimed at enhancing the overall performance of MC services (as measured by Key Performance Indicators - KPIs) and effectively managing scenarios with a high volume of simultaneous communications, which is critical for mission-critical applications.
