14.2 ^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.
