Question: In a Universal Subscriber Identity Module (USIM) Application Toolkit (USAT), for an ENVELOPE command related to Geographical Location Reporting, sent from the Mobile Equipment (ME) to the UICC, what is the specified destination for device identities within the command parameters?
Option 1: Source: UICC; Destination: ME
Option 2: Source: ME; Destination: Network Server
Option 3: Source: ME; Destination: UICC
Option 4: Source: Network; Destination: ME
Explanation: According to the USIM Application Toolkit specifications for Geographical Location Reporting, when the Mobile Equipment (ME) sends an ENVELOPE command to the UICC, the device identities within the command parameters are set with the ME as the source and the UICC as the destination. This ensures that the location information is correctly directed from the ME to the UICC for processing or storage.
