Question: How can a User Equipment (UE) typically acquire the HTTP URL to obtain User Service Description (USD) information via unicast for Multimedia Broadcast/Multicast Service (MBMS)?
Option 1: Only through a push notification from the network.
Option 2: Through pre-storage in the UE, pre-storage in the MBMS application, acquisition via OMA PUSH, or resolution from the Service Announcement Fully Qualified Domain Name (FQDN).
Option 3: Exclusively by resolving it from a predefined, operator-specific FQDN.
Option 4: Solely through a broadcast message on the MBMS channel.
Explanation: The correct answer is Option 2 because, according to standard practices in telecom networks for MBMS, UEs can obtain necessary URLs through various methods to ensure flexibility and reliability. These include having the URL pre-stored directly in the UE, within the MBMS application, acquiring it via OMA PUSH, or resolving it from a Service Announcement FQDN, which is standardized for consistency across networks.
