Question: What happens when a Mobile Equipment (ME) receives a LAUNCH BROWSER command but is currently engaged in a Server-Side (SS) transaction?
Option 1: The ME pauses the SS transaction, launches the browser with the provided URL, and then resumes the SS transaction.
Option 2: The ME rejects the command, sending a TERMINAL RESPONSE to the UICC indicating it is currently unable to process the command due to being busy on an SS transaction.
Option 3: The ME queues the LAUNCH BROWSER command to execute immediately after completing the ongoing SS transaction.
Option 4: The ME ignores the LAUNCH BROWSER command without notifying the UICC, prioritizing the completion of the SS transaction.
Explanation: When an ME receives a LAUNCH BROWSER command while being busy with a Server-Side (SS) transaction, it must prioritize handling the current transaction to maintain integrity and continuity. Given this scenario, the most appropriate action is for the ME to communicate its unavailability by rejecting the command and sending a TERMINAL RESPONSE to the UICC, informing it of the ME's current inability to process the LAUNCH BROWSER command due to being engaged in an SS transaction, ensuring transparency for potential re-attempts or alternative actions.
