16.2^SSTN SAT Notification

Unsolicited Result Codes

URC 1

Proactive Command notification

^SSTN: <cmdType>

Every time the SIM Application issues a Proactive Command, via the ME, the TA will receive a notification. This indicates the type of Proactive Command issued.

AT^SSTGI must then be used by the TA to request the parameters of the Proactive Command from the ME. Upon receiving the ^SSTGI response from the ME, the TA must send AT^SSTR to confirm the execution of the Proactive Command and provide any required user response, e.g. a selected menu item.

URC 2

Terminate Proactive Command notification

^SSTN: <cmdTerminateValue>

When the SIM application has issued a Proactive Command to the ME, it is possible that this command will be terminated later. URC "^SSTN" is sent with a different Proactive Command type number (added terminate offset 100) to indicate the termination of the specified command.

The state changes to idle. Therefore the TA should avoid sending any further commands related to the ter- minated Proactive Command, e.g. AT^SSTGI or AT^SSTR.

URC 3

Notification that SIM Application has returned to main menu

^SSTN: 254

Notification to the TA when the SIM Application has finished a command cycle and again enters its main menue, which was transferred with an URC "^SSTN: 37" (SET UP MENU) at start up.

This URC should be used to open this menue on the sreen.

The TA does not need to respond directly, i.e. AT^SSTR is not required.

URC 4

SIM reset notification

^SSTN: 255

Notification to the TA if a Proactive Command "REFRESH - SIM Reset" has been issued by the SIM Applica- tion, please refer to AT^SSTGI.

This URC should be used to set the TAs application to its initial state since the SIM Application will start from the beginning, too.

The TA does not need to respond directly, i.e. related AT^SSTGI and AT^SSTR are neither required nor allowed.

Since the ME is still busy on SIM access the ME may respond with "+CME ERROR: SIM blocked" or "+CME

ERROR: SIM busy" on following PIN required AT Commands for a while. Then TA shall retry until the ME responds with "OK". The time needed for this process depends on the SIM and may take more than 10 sec- onds.
