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), mes-
sage receiving should be done as specified in GSM 03.38.
Note:
the rules <mt>=2 and <mt>=3 for storing received SM are possible
only if phase 2+
compatibility is activated with +CSMS=1
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, in-
dications 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 reserved (e.g.
in on-line data mode) and flush them to the TE after reservation. Otherwise
forward them directly to the TE.
3
Forward unsolicited result codes directly to the TE. TA-TE link specific in-
band technique used to embed result codes and data when TA is in on-line
data mode.
<mt>
(the rules for storing received SMs depend on the relevant data coding 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.
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: [<alpha>], <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 in-
dication as defined in <mt>=1.
