TA selects the procedure how the receipt of new 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), message receiving should be done as
specified in GSM 03.38 ( see [5]).
Notes
1) If the DTR signal is not available or the state of the signal is ignored
(V.250 command &D0), reliable message transfer can be assured by
using AT+CNMA acknowledgement procedure.
2)
The rules <mt
>=2 and <mt>=3 for storing received SM are possible only
if phase 2+ compatibility is activated with AT+CSMS=1
3)
The parameter <ds
>=1 is only available in phase 2+
Test command Response:
AT+CNMI=?
+CNMI: (list of supported <mode
>s),(list of supported <mt>s),(list of supported
<bm
>s),(list of supported <ds>s),(list of supported <bfr>s)
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
<mt
>
Rules for storing received SMS depend on the relevant data
coding method (refer to GSM 03.38, ( see [5]) ), preferred
memory storage AT+CPMS) setting and this value
Note
If the 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
1
If SMS-DELIVER is stored in ME/TA, indication of the
memory location is routed to the TE using unsolicited result
code
+CMTI: <mem>,<index>
2
SMS-DELIVERs, except class 2 messages and messages in
the message waiting indication group (store message), are
routed directly to the TE using unsolicited result code:
+CMT: <length><CR><LF<>pdu> (PDU mode enabled)
3
Class 3 SMS-DELIVERs are routed directly to the TE using
unsolicited result codes defined in <mt
>=2. Messages of
other data coding schemes result in indication as defined in
<mt
>=1.
<bm
>
Rules for storing received CBMs depend on the relevant data
coding method (refer to GSM 03.38 ( see [5])), the setting of
Select CBM Types AT+CSCB) and these values:
0
No CBM indications are routed to the TE.
2
New CBMs are routed directly to the TE using unsolicited
result code:
+CBM: <length><CR><LF><pdu> (PDU mode enabled)
Note
The settings of command AT+CNMI and AT+CSCB have to
be done on the same Serial Interface.
<ds

No SMS-STATUS-REPORTs are routed to the TE
