but can be used in PDU mode (+CMGS).
SRR: Status Report Request, b5=1 if a status report is requested. This mode is supported.
VPF: Validity Period Format
b4=0 & b3=0 -> <vp> field is not present
b4=1 & b3=0 -> <vp> field is present in relative format
Other formats (absolute & enhanced) are not supported.
RD: Reject Duplicates, b2=1 to instruct the SC to reject an SMS-SUBMIT for an SM still
held in the SC which has the same <mr> and the same <da> as the previously submitted SM
from the same <oa>
MTI: Message Type Indicator
b1=0 & b0=0 -> SMS-DELIVER (in the direction SC to MS)
b1=0 & b0=1 -> SMS-SUBMIT (in the direction MS to SC)
In text mode <vp> is only coded in “relative” format. The default value is 167 (24 hours).
This means that one byte can describe different values:
VP value Validity period value
0 to 143 (VP + 1) x 5 minutes (up to 12 hours)
144 to 167 12 hours + ( (VP – 143) x 30 minutes )
168 to 196 (VP – 166) x 1 day
197 to 255 (VP – 192) x 1 week
<pid> is used to indicate the higher layer protocol being used or indicates inter-working with a
certain type of telematic device. For example, 0x22 is for group 3 fax, 0x24 is for voice telephone,
0x25 is for ERMES (European Radio Messaging System).
<dcs> is used to determine the way the information is encoded. Compressed text is not
supported. Only GSM default alphabet, 8 bit data and UCS2 alphabet are supported.
