Question: What is the implication of setting the TP-Status-Report-Request field to '1' in an SMS-SUBMIT or SMS-COMMAND message in a mobile network?
Option 1: A delivery report will be sent to the sender upon successful receipt by the User Equipment (UE), indicating the message has been delivered.
Option 2: The message will be prioritized over others in the queue, ensuring faster transmission.
Option 3: The recipient's UE will automatically respond with an acknowledgement without user interaction.
Option 4: The sender's UE will receive periodic updates on the network's health while the message is being delivered.
Explanation: Setting the TP-Status-Report-Request field to '1' specifically requests a status report, which in the context of SMS, typically implies a delivery report. This report informs the sender about the delivery status of the message to the intended recipient's UE, thus ensuring transparency and feedback on the message's journey. This is crucial for senders needing confirmation of successful delivery, especially in applications where receipt acknowledgment is vital (e.g., banking updates, security alerts).
