Question: During PDU session establishment, if the USIM responds with '93 00' to the ENVELOPE (CALL CONTROL) command, how should the Mobile Equipment (ME) proceed?
Option 1: Send the PDU Session Establishment Request message as originally proposed.
Option 2: Do not send the PDU Session Establishment Request message and may retry the command.
Option 3: Establish the PDU session using default settings.
Option 4: Terminate the USIM service for call control on PDU sessions.
Explanation: When the USIM responds with '93 00', it indicates that the ME should not proceed with sending the PDU Session Establishment Request message as is, but instead, may retry the command. This response allows for potential adjustments or retries based on the USIM's evaluation, ensuring alignment with the call control service's requirements before establishing the PDU session.
