Question: What is the primary purpose of an Internal-Group Identifier in a 5G network?
Option 1: To uniquely identify individual User Equipment (UE) within a network.
Option 2: To group multiple Subscription Permanent Identifiers (SUPIs), such as those for Machine Type Communication (MTC) devices, for a specific group-related service.
Option 3: To differentiate between various network slices in a 5G architecture.
Option 4: To enhance security for roaming subscribers by masking their IMSI.
Explanation: An Internal-Group Identifier is designed to group multiple SUPIs (e.g., those belonging to MTC devices) together, facilitating the provision of specific group-related services, which supports efficient service delivery and management within the network, particularly for IoT or MTC use cases.
