Question: In an MBMS file repair scenario, when multiple UEs request download data over a short period, what response from the MBMS file repair server is most desirable for efficient data delivery?
Option 1: Return a repair response message with encoding symbols as HTTP payload to each UE individually.
Option 2: Redirect the clients to a broadcast/multicast delivery (an MBMS download session) for the repaired data.
Option 3: Provide the requested file or file groups directly through point-to-point HTTP delivery to all requesting UEs simultaneously.
Option 4: Return an HTTP error code indicating server overload, prompting UEs to retry later.
Explanation: When multiple UEs request the same download data over a short period, redirecting them to a broadcast/multicast delivery (an MBMS download session) is more efficient. This approach reduces network load by transmitting the repaired data only once over the air interface, rather than sending individual responses to each UE, thus optimizing resource utilization and enhancing overall network performance.
