All messages
<index>
Integer type value in the range of location numbers supported by the associated
memory
<da>
Destination Address. 3GPP TS 23.040 TP-Destination-Address Address-Value field in
string format. BCD numbers (or GSM 7 bit default alphabet characters) are
converted to characters of the currently selected TE character set (refer to
AT+CSCS
command in
3GPP TS 27.007
). The type of address is given by
<toda>
.
<oa>
Originating address. 3GPP TS 23.040 TP-Originating-Address Address-Value field in
string format. BCD numbers (or GSM 7 bit default alphabet characters) are converted
to characters of the currently selected TE character set (refer to
AT+CSCS
command
in
3GPP TS 27.007
). The type of address is given by
<tooa>
.
<alpha>
String type alphanumeric representation of
<da>
or
<oa>
corresponding to the entry
found in MT phonebook. Implementation of this feature is manufacturer specified. The
used character set should be the one selected with
AT+CSCS
command (see
definition of this command in
3GPP TS 27.007
).
<scts>
Service center time stamp. 3GPP TS 23.040 TP-Service-Centre-Time-Stamp in
time-string format (refer to
<dt>
).
<toda>
Type of recipient address. 3GPP TS 24.011 TP-Recipient-Address Type-of-Address
octet in integer format.
<tooa>
Type
of
originating
address.
3GPP
TS
24.011
TP-Originating-Address
Type-of-Address octet in integer format (default refer to
<toda>
).
<length>
Message length. Integer type. Indicating in the text mode (
AT+CMGF=1
) the length
of the message body
<data>
(or
<cdata>
) in characters, or in PDU mode
(
AT+CMGF=0
) the length of the actual TP data unit in octets (i.e. the RP layer SMSC
address octets are not counted in the length).
<data>
In the case of SMS: 3GPP TS 23.040 TP-User-Data in text mode responses; format:
- If
<dcs>
, indicates that 3GPP TS 23.038 GSM 7 bit default alphabet is used and
<fo>
indicates that 3GPP TS 23.040 TP-User-Data-Header-Indication is not set.
- I
f TE character set other than “HEX” (refer to
AT+CSCS
command in
3GPP TS
27.007
): ME/TA converts GSM alphabet into current TE character set according to
rules of
Annex A
in
3GPP TS 27.007
.
- I
f TE character set is “HEX”: ME/TA converts each 7-bit character of GSM 7 bit
default alphabet into two IRA character long hexadecimal number (e.g. character
(GSM 7 bit default alphabet 23) is presented as 17 (IRA 49 and 55)).
- If
<dcs>
, indicates that 8-bit or UCS2 data coding scheme is used, or
<fo>
indicates that 3GPP TS 23.040 TP-User-Data-Header-Indication is set: ME/TA
converts each 8-bit octet into two IRA character long hexadecimal number (e.g.
octet with integer value 42 is presented to TE as two characters 2A (IRA 50 and
65)).
In the case of CBS: 3GPP TS 23.041 CBM Content of Message in text mode
responses; format:
- If
<dcs>
, indicates that 3GPP TS 23.038 GSM 7 bit default alphabet is used:
-
If TE character set other than “HEX” (refer to
AT+CSCS
command in
3GPP
TS27.007
): ME/TA converts GSM alphabet into current TE character set according
