Reference Note
GSM 07.05
Version 8 dated 15.03.00
GSM 03.40 TP-Destination-Address Address-Value field in string format; BCD
numbers (or GSM default alphabet characters) are converted into characters; type of
address given by <toda>
GSM 04.11 TP-Destination-Address Type-of-Address octet in integer format (when
first character of <da> is + (IRA 43) default is 145, otherwise default is 129)
integer type value indicating in the text mode (+CMGF=1) the length of the message
body <data> (or <cdata>) in characters; or in PDU mode (+CMGF=0), the length of
the actual TP data unit in octets (i.e. the RP layer SMSC address octets are not coun-
ted in the length)
GSM 03.40 TP-Message-Reference in integer format
GSM 03.40 TP-Service-Centre-Time-Stamp in time-string format (refer <dt>)
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"
GSM 03.40 RP-User-Data element of RP-ACK PDU; format is same as for <pdu>
in case of SMS, but without GSM 04.11 SC address field and parameter shall be
enclosed in double quote characters like a normal string type parameter
In the case of SMS: GSM 04.11 SC address followed by GSM 03.40 TPDU in he-
xadecimal format: ME/TA converts each octet of TP data unit into hexadecimal
numbers containing two IRA characters (e.g. octet with integer value 42 is presented
to TE as two characters 2A (IRA 50 and 65)). In the case of CBS: GSM 03.41 TPDU
in hexadecimal format.
