The system receives a request from the UE to enable the negative acknowledgment for an inner socket of the tunnel and sends a response back to the UE to indicate that the negative acknowledgment is enabled for the inner socket. The system receives a plurality of frames from the UE on the inner socket, where each frame includes a sequence number. The system, for each frame received, determines an inter-frame delay using the sequence number, and based on the inter-frame delay determines one or more missing frames. The system then sends an identity of the missing frames to the UE on the inner socket."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Negative acknowledgment of tunneled encapsulated media","description":"A system for performing negative acknowledgment for real-time communications establishes a tunnel by a tunneling server with a tunneling client of a user equipment (UE).
