Question: In a Localised Service Area (LSA) scenario, how is the notification of a change in current LSA to service subscribers typically handled?
Option 1: The network mandates a standardized display format for all devices, ensuring uniformity across manufacturer platforms.
Option 2: The form of display and indication are left to the manufacturer's choice, with the network specifying the trigger for notification.
Option 3: Subscribers are not notified of LSA changes; instead, the network silently adjusts service provisions based on the new LSA.
Option 4: Notification is always performed through a dedicated app, which must be installed by the subscriber to receive LSA updates.
Explanation: This answer reflects the flexibility given to device manufacturers in how they choose to display and indicate changes in the Localised Service Area (LSA) to subscribers, while the network retains control over when such notifications are triggered. This approach balances user experience with network operational needs, aligning with typical telecom practices where networks define service triggers but leave the implementation details (like UI elements) to device manufacturers.
