Question: In the context of the Nimsas_SessionEventControl service, what happens to IMS AS processing of a session event when notifying NFs (e.g., DCSF) until the consumer acknowledges reception?
Option 1: IMS AS continues processing and forwards the event immediately to the calling/called party.
Option 2: IMS AS pauses processing of the session event, awaiting acknowledgement before proceeding.
Option 3: The consumer is required to invoke Nimsas_MediaControl service to resume IMS AS processing.
Option 4: NFs (e.g., DCSF) take over the session event processing temporarily.
Explanation: This is correct because, according to the service description, when an IMS session control event notification is sent to Network Functions (NFs), the IMS Application Server (IMS AS) pauses its processing of the session event. This pause continues until the consumer acknowledges the reception of the session event notification, allowing for potential application of media control or policies before proceeding.
