TC63 AT Command Set

13.1 SMS parameters

s

<dt>(num)

Discharge Time

GSM 03.40 TP-Discharge-Time in time-string format: "yy/MM/dd,hh:mm:ss+zz", where characters indicate year (two last digits), month, day, hour, minutes, seconds and time zone. For example, 6th of May 1994, 22:10:00 GMT+2 hours equals "94/05/06,22:10:00+08"

<ieia>(num)

IEIa (Information Element Identifier octet) of the concatenated SMS.

8	Concatenated short messages, 8-bit reference number
16	Concatenated short messages, 16-bit reference number

<index>(num)

Integer type; value in the range of location numbers supported by the associated memory

<length>(num)

Message Length

Integer type value 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) In text mode, the maximum length of an SMS depends on the used coding scheme: It is 160 characters if the 7 bit GSM coding scheme is used, and 140 char- acters according to the 8 bit GSM coding scheme.

If the SMS message format is ''text mode'' (AT+CMGF=1) and the character set is set to ''UCS2'' with AT+CSCS and the SMS is also coded as "UCS2" (see <dcs> of AT+CSMP), then the length is in octets instead of charac- ters.

For concatenated SMS messages the maximum length will be reduced by the length of the user data header with respect to <ieia> (6 bytes for <ieia>=8 and 7 bytes for <ieia>=16). In the case of 8-bit data, the max- imum length of the short message field is: 140 octets - (6 or 7) = 134 or 133. In the case of GSM 7 bit default alphabet data, the maximum length of the short message is (140 - (6 or 7))*8/7 = 153 or 152 characters. In the case of 16 bit UC2 data, the maximum length of the short message is: (140 - (6 or 7))/2)= 67 or 66 characters.

<max>(num)

Maximum number of all segments to be concatenated into one SMS, beginning with 1. <max>=0 means: ignore the value. This will result in a non-concatenated SMS.

0...255

<mem1>(str)

Memory to be used when listing, reading and deleting messages:

“SM“	SIM message storage
“ME“	Mobile Equipment message storage
“MT“(D)	Sum of "SM" and "ME" storages

<mem2>(str)

Memory to be used when writing and sending messages:

“SM“	SIM message storage
“ME“	Mobile Equipment message storage
“MT“(D)	Sum of "SM" and "ME" storages
