However, be aware that this Elementary File data can be changed at any time
by the network provider or an application running on the SIM. For details refer
to
feature "Data Download to SIM" in 3GPP TS 11.14
. If this happens
the TE urgently needs to refresh its internal representation (i.e. copy) of the
changed data to ensure its safe and consistent use!
Therefore, a "
: "simdata"" URC is issued if ME is in
Auto-
REFRESH command indi-
cating that the content of one or more Elementary Files has been changed.
“simtray“
Indication of SIM tray status as indicated by CCIN line. Result does not depend
on whether the tray holds a SIM or not.
Generating a URC on status change is not supported.
“vmwait1“
Voice Message Waiting Indication for line 1
"vmwait1" and "vmwait2" indicate the receipt of a special short message with
a Voice Message Waiting Indicator. The service must be provisioned by the
operator.
The numbers 1 or 2 in "vmwait1" and "vmwait2" are related to the two lines of
the Alternate Line Service (ALS), also defined in CPHS Phase 2 standard. For
further details refer to the
command.
The presentation mode of the indicator varies with the operator: If more than
one message are waiting, some operators only indicate the first one, others
deliver the indicator each time a new voice message is put into the mailbox.
After the subscriber has retrieved all voice messages the service center auto-
matically sends another message indication which provides the value 0.
Some operators may also send the number of waiting voice messages along
with the indication. In this case, the number will be displayed by the ME as part
of the URC. For example, "+CIEV: vmwait1,1,5" notifies that five new voice
messages are waiting. However, it should be noted that neither the read com-
mand
? nor the write command
,2 display the
number of waiting messages.
The "vmwait" indicators do not apply if a network provider signals new voice
mail(s) via standard SMS. In this case the indicator "message" will be displayed
(see
“vmwait2“
Voice Message Waiting Indication for line 2
“ciphcall“
Ciphering Status Change Indication
As stated in GSM specifications 02.07 and 02.09 the ciphering indicator feature
allows the ME 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
3GPP TS 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.
The following restrictions apply if the same serial channel is used for
0
SIM tray empty.
1
SIM tray plugged in.
0
The value 0 notifies that no new voice message is available, and is pro-
vided by the service center to clear the voice message indication after
the subscriber has retrieved all voice messages.
1
The value 1 notifies the subscriber that the mailbox contains one or
several messages.
