Question: In a secured Short Message Point to Point for (U)SIM Toolkit applications, what happens when a Response Packet is too large to fit into a single SMS-DELIVER-REPORT and the Command Packet's SPI2 indicates sending back a Delivery Report using SMS-DELIVER-REPORT?
Option 1: The Response Packet is truncated to fit within a single SMS-DELIVER-REPORT.
Option 2: Multiple SMS-DELIVER-REPORTs are sent, each containing a part of the Response Packet.
Option 3: A single SMS-DELIVER-REPORT with a specific Response Status Code is sent first, followed by the complete Response Packet in one or more SMS-SUBMIT elements.
Option 4: The Response Packet is sent as is, without any modifications, in a single SMS-DELIVER-REPORT.
Explanation: This option correctly reflects the procedure for handling oversized Response Packets when an SMS-DELIVER-REPORT is specified but cannot contain the entire response. It involves sending an initial SMS-DELIVER-REPORT with a specific status code, indicating that the actual response will follow in one or more SMS-SUBMIT elements, ensuring complete delivery of the Response Packet while adhering to the communication protocol.
