Question: How are configuration parameters prioritized for MBMS (Multimedia Broadcast/Multicast Service) download sessions when received both out-of-band and in-band?
Option 1: The oldest configuration file with the lowest version number takes priority, ensuring initial defaults are always used.
Option 2: Configuration parameters are merged, with out-of-band settings taking precedence for initial defaults and in-band updates overwriting only unspecified parameters.
Option 3: The most recently delivered configuration file (with the highest version number) takes priority, allowing in-band parameters to overwrite earlier received out-of-band settings.
Option 4: Priority is determined by the UE (User Equipment), which can choose between out-of-band and in-band configurations based on its current state.
Explanation: This correct answer reflects the dynamic update mechanism for MBMS delivery procedures, where the latest configuration file (identified by its version number) supersedes previous settings. This ensures that parameters can be updated quickly during a session if needed, aligning with the desire for flexibility in scenarios with minimal dynamics. The explanation highlights the practical implication of this prioritization in telecom networks, specifically in managing MBMS sessions efficiently.
