Question: What is the primary purpose of authorization in the context of indirect network connections in the 5G system?
Option 1: To restrict access to specific network services
Option 2: To enable network operators to control which UEs can act as relay UEs and for whom they can relay traffic
Option 3: To prioritize traffic from certain application layer groups
Option 4: To limit the number of simultaneous connections
Explanation: The correct answer is Option 2 because authorization in this context allows network operators to control which UEs can act as relay UEs and for whom they can relay traffic, ensuring that only authorized devices can participate in indirect network connections. This is crucial for maintaining security and preventing unauthorized access or misuse of the network.
