Question: What is the primary purpose of the `Notify_Unified_Traffic_Pattern_Update` operation in the context of Service Enabler Architecture Layer for Verticals (SEAL)?
Option 1: To update UE unified traffic patterns in response to changes in network congestion.
Option 2: To notify VAL servers of updates to UE unified traffic patterns, ensuring synchronized management.
Option 3: To request UE location information from the network for enhanced services.
Option 4: To initiate a handover procedure between different access networks.
Explanation: The `Notify_Unified_Traffic_Pattern_Update` operation is specifically designed to inform, or notify, the VAL (Vertical Application Layer) server about any updates that occur in the unified traffic patterns of User Equipment (UE). This notification process ensures that the VAL server maintains an up-to-date understanding of UE traffic patterns, which is crucial for optimized service delivery and management in vertical industries.
