Response
TA selects the procedure how the receipt of new SMS messages from the network
is indicated to the TE when TE is active, e.g. DTR signal is ON. If TE is inactive
(e.g. DTR signal is OFF), the reception of messages shall be performed as speci-
fied in GSM 03.38.
Note1: If the DTR signal is not available or the state of the signal is ignored
(V.25ter command &D0), reliable message transfer can be assured b y us-
ing +CNMA acknowledgment procedure.
Note2: The rules <mt>=2 and <mt>=3 for storing received SM are possible only if
phase 2+ compatibility is activated with +CSMS=1
Note3: The parameter <ds>=1 is only available in phase 2+
OK
If error is related to ME functionality:
+CMS ERROR: <err>
Parameter
<mode> 0 Buffer unsolicited result codes in the TA. If TA result code
buffer is full, indications can be buffered in some other place or
the oldest indications may be discarded and replaced with the
new received indications.
1 Discard indication and reject new received message
unsolicited result codes when TA-TE link is reserved (e.g. in
on-line data mode). Otherwise forward them directly to the TE.
2 Buffer unsolicited result codes in the TA when TA-TE link is r e-
served (e.g. in on-line data mode) and flush them to the TE af-
ter reservation. Otherwise forward them directly to the TE.
3 Forward unsolicited result codes directly to the TE. TA-TE link
specific inband technique used to embed result codes and data
when TA is in on-line data mode.
<mt> Rules for storing received SMS depend on the relevant data codin g
method (refer to GSM 03.38 [2]), preferred memory storage (+CPMS)
setting and this value
Note: If AT command interface is acting as the only display device, the
ME must support storage of class 0 messages and messages in the
message waiting indication group (discard message)
0 No SMS-DELIVER indications are routed to the TE.
