Question: How can a client obtain session parameters for an MBMS (Multimedia Broadcast/Multicast Service) download session to receive a User Service Announcement?
Option 1: Via SMS notification containing the session details.
Option 2: By pre-storing the related session parameters in the MBMS UE or application, or through acquisition methods like OMA PUSH or downloading from an HTTP server resolved from a specified FQDN.
Option 3: Through direct input by the user based on information provided on the service provider's website.
Option 4: Downloading the session parameters from an HTTP server using a standardized URL (e.g., `http://mbmsbs.mnc<MNC>.mcc<MCC>.pub.3gppnetwork.org/bootstrap.multipart`).
Explanation: The correct answer, Option 4, aligns with the detailed specification for obtaining session parameters through a standardized HTTP URL, which ensures consistency and reliability in accessing MBMS services across different networks. While Option 2 mentions some correct methods, it lacks specificity regarding the HTTP download process, making Option 4 the more precise answer.
