Question: In a Gateway Control Session Establishment for Emergency Services, what CC-Request-Type AVP value is set by the BBERF when requesting QoS Rules?
Option 1: UPDATE_REQUEST
Option 2: TERMINATION_REQUEST
Option 3: EVENT_REPORTING
Option 4: INITIAL_REQUEST
Explanation: When a BBERF (Broadband BRAS (Border Router) or Edge Router Function) initiates a Gateway Control Session for Emergency Services and requests QoS (Quality of Service) Rules, it must signal the start of the session. The CC-Request-Type AVP (Attribute Value Pair) set to "INITIAL_REQUEST" indicates the beginning of a new session, which is crucial for establishing the necessary QoS for emergency services. This ensures that the network prioritizes and allocates appropriate resources for these critical communications.
