Parameter Description
Integer type value in the range stated below for the corresponding <indDescr>.
String values and their
<indValue> ranges.
All indicators supported by
AT+CIND are accessible with this command, too. A detailed description of these indi-
cators can be found there.
The following indicators are accessible via
AT^SIND only:
“netlost“ 0 .. Network registration or location update succeeded.
1 .. Network registration or location update failed because of bad uplink con-
nection.
“ciphcall“ Ciphering Status Change Indication
As stated in GSM specifications 02.07 and 02.09 the ciphering indicator feature
allows the MC35i to detect that ciphering is not switched on and to indicate this
to the user.
The ciphering indicator feature may be disabled by the home network operator
setting data in the "administrative data" field (EF
AD
) in the SIM, as defined in
GSM 11.11.
If this feature is not disabled by the SIM, then whenever a connection is in
place, which is, or becomes unenciphered, an indication shall be given to the
user. This enables the user's decision how to proceed.
Read command returns valid ciphering status only if a call is in progress or
active.
If EF
AD
setting disables the ciphering indicator feature read command always
indicates a ciphered link and no URC presentaion will take place.
Note:
The following restrictions apply if the same serial channel is used for
AT^SIND
"ciphcall" indication and for the action triggering this URC. In general, the rec-
ommended solution is to use a dedicated channel for all status signalling via
URCs.
• If an unciphered mobile originated SMS is performed,
AT^SIND "ciphcall"
URCs on the same serial channel will be issued after the related "OK" and
indicate the ciphering state at this time. Because the SMS is already sent at
this time, two URCs will be issued on this channel, but both are indicating
that ciphering is enabled.
• If an unciphered mobile originated data call is performed,
AT^SIND "ciph-
call" URCs on the same serial channel will be issued after the interface is
not longer blocked by the call (call is released or temporarily stopped) and
indicate the ciphering state at this time.
0 .. Current call or SMS is not ciphered.
1 .. Current call or SMS is ciphered.
