Question: In a Secured Packet Structure for (U)SIM Toolkit applications, where is the Response Packet generated when the Receiving Entity is the UICC, and how is it subsequently transmitted?
Option 1: Generated on the Mobile Equipment (ME), directly sent to the network without UICC involvement.
Option 2: Generated on the UICC, retrieved by the ME, but sent directly to the Sending Application without a Facility message.
Option 3: Generated on the network, sent to the UICC for storage, then retrieved by the ME and included in a Return Result Component.
Option 4: Generated on the UICC, retrieved by the Mobile Equipment (ME) from the UICC, and included in the Return Result Component of a Facility message returned to the network.
Explanation: This is correct because when the Receiving Entity is the UICC, the Response Packet's generation and transmission follow a specific path for secure and structured communication. The UICC generates the packet, ensuring security and integrity. The Mobile Equipment (ME) then retrieves this packet from the UICC and includes it in a Facility message's Return Result Component, which is subsequently sent back to the network. This process ensures that the response is securely handled and communicated through the defined protocol, aligning with the principles of secured packet structures for (U)SIM Toolkit applications.
