Question: In a UE-elected offloading scenario, how does the network proxy server redirect a MooD-capable UE's HTTP GET request for a large, non-real-time (NRT) file object to an MBMS bearer?
Option 1: By an HTTP 2xx/Success response containing the requested content and a MooD header field
Option 2: By an HTTP 3xx/Redirection response requiring the UE to obtain the file via the MBMS download method
Option 3: By an RTSP PLAY request message switching the UE to MBMS reception
Option 4: By an OMA-DM based MooD Configuration MO update
Explanation: In UE-elected offloading, for large NRT file objects requested via HTTP GET, the network efficiently utilizes resources by redirecting the UE to receive the content over an MBMS bearer. This is achieved through an HTTP 3xx/Redirection response, which instructs the UE to obtain the file using the MBMS download method, thereby offloading unicast traffic and optimizing network resource utilization.
