Question: Which of the following is a requirement for providing the Voice Broadcast Service (VBS) in a Public Land Mobile Network (PLMN)?
Option 1: The service must be provisioned via a GERAN A/Gb mode of operation.
Option 2: The service can be provided through any RAN technology (e.g., UTRAN, E-UTRAN, etc.).
Option 3: The service is exclusively for subscribers in idle mode.
Option 4: The service requires a minimum of two simultaneous voice calls.
Explanation: This is correct because, according to the specifications, the Voice Broadcast Service (VBS) shall only be provided via a GERAN A/Gb mode of operation, indicating a specific technical requirement for the service's provisioning. This highlights the importance of infrastructure compatibility in supporting particular telecommunication services. In practical telecom scenarios, understanding such requirements is crucial for ensuring seamless service delivery and planning network upgrades or expansions. (GERAN: GSM/EDGE Radio Access Network)
