Question: In a 5G System supporting Mission Critical (MC) services, what is the primary characteristic of UE 4 in relation to another UE type?
Option 1: UE 4 has enhanced security features compared to UE 3.
Option 2: UE 4 supports only voice services, unlike UE 3 which supports data.
Option 3: UE 4 represents one or more UEs with the same functionality as UE 3.
Option 4: UE 4 is specifically designed for MCPTT (Mission Critical Push To Talk) services, differing from UE 3.
Explanation: This answer highlights that UE 4 is essentially identical in functionality to UE 3, indicating a duplication or equivalence in their roles within the network for MC services. This understanding is crucial for telecom operators to ensure seamless service provision across supposedly identical user equipment types.
