Question: Which of the following functional entities is NOT typically associated with UE 3's configuration for off-network Mission Critical (MC) services using ProSe?
Option 1: Configuration Management Client
Option 2: Group Management Client
Option 3: Mobility Management Entity (MME)
Option 4: MC Service Clients
Explanation: UE 3, for off-network Mission Critical services using ProSe, is composed of specific functional entities. These include a Configuration Management Client for managing settings, a Group Management Client for handling group communications, and MC Service Clients for the actual mission-critical service applications. However, Mobility Management Entity (MME) is a network element typically involved in LTE/5G core network's mobility management and not a functional entity within a UE (User Equipment) for off-network ProSe operations. Thus, MME is not associated with UE 3's configuration for these services.
