Question: What is a characteristic of User Service Announcement over point-to-point push bearers in MBMS, regarding the transmission of metadata envelope and fragments?
Option 1: The metadata envelope must always be transmitted to the MBMS terminal, with fragments embedded within.
Option 2: Transmission of both metadata envelope and fragments is optional, but if sent, they can be separate MIME containers.
Option 3: Only metadata fragments are transported; the metadata envelope is not required for point-to-point push bearers.
Option 4: If both are transported, metadata fragments must either be embedded within the metadata envelope or referenced within a multipart MIME container.
Explanation: This correct answer highlights a specific technical requirement for how metadata envelopes and fragments are handled when using point-to-point push bearers for User Service Announcements in MBMS, reflecting detailed handling of metadata as per telecom standards.
