Question: How is the priority of Filter Description metadata fragments determined for MBMS (Multimedia Broadcast/Multicast Service) clients when received through different means?
Option 1: By the order in which they are received, with the first one having the highest priority.
Option 2: Based on the size of the fragment, with larger fragments taking precedence.
Option 3: Through a manual selection process by the UE (User Equipment) based on user preferences.
Option 4: By the version number indicated in the MBMS Metadata Envelope, with the highest version number taking priority.
Explanation: In MBMS, to ensure that the most current filter settings are applied, the priority of Filter Description metadata fragments is determined by their version number as specified in the MBMS Metadata Envelope. This approach guarantees that the latest fragment (with the highest version number) overwrites previous settings, whether those were received in-band, out-of-band, or through a dedicated session for filter metadata transport. This method ensures consistency and accuracy in applying filter data parameters across different sessions and announcements.
