Question: In the context of USIM Application Toolkit (USAT), for an EVENT DOWNLOAD – (I-)WLAN Access Status command, what is the specified direction and what should be the setting for the 'destination' in device identities?
Option 1: Network to UICC; Destination: Terminal
Option 2: Terminal to UICC; Destination: Terminal
Option 3: UICC to Terminal; Destination: UICC
Option 4: Terminal to UICC; Destination: UICC
Explanation: According to the USIM Application Toolkit specifications, for an EVENT DOWNLOAD – (I-)WLAN Access Status command, the direction is from the terminal to the UICC. Additionally, in the device identities section of the command parameters, the destination should be set to UICC, indicating that the event report is being sent to the UICC from the terminal. This setup is crucial for proper communication and status update between the terminal and the UICC regarding (I-)WLAN access.
