Question: What is the primary purpose of attributes associated with an MC (Mission Critical) service ID in the context of MC services, such as MCPTT (Mission Critical Push To Talk)?
Option 1: To enhance voice quality for emergency responders
Option 2: To facilitate authorization decisions by the MC service server regarding service access and privileges
Option 3: To prioritize data traffic over voice communications in congested networks
Option 4: To enable interoperability between different wireless network technologies
Explanation: Attributes associated with an MC service ID, such as a user's role or organization, are crucial for the MC service server to make informed decisions about which services and privileges (e.g., administrative rights over group creation) to grant to the user. This ensures that access to sensitive or specialized functions within the MC services is appropriately controlled, enhancing security and operational efficiency.
