EMI - UCP interface specification v4.6 with ucplib
Setup
First we need to import the UcpMsg form the library >>> from ucplib import UcpMsg
General examples
The SMT sends a message to the SMSC with text “hello” in the GSM 7-bit alphabet. Note that “hello†in ASCII has the same encoding.
‘49/00078/O/51/0031612345678/55555/////////////////3//68656C6C6F/////////////0D’
Specific types
Type 01 messages
Operation
Alphanumeric message ‘Short Message’ to receiver 01234567890 from sender 09876543210
>>> msg = UcpMsg( o_r=“O”, ot=01, adc=“01234567890”, oadc=“09876543210”, mt=3, amsg=u“Short Message”) >>> print msg 00/00070/O/01/01234567890/09876543210//3/53686F7274204D657373616765/D9
Now let’s try to parse the message and see if wo obtain the same result
>>> print UcpMsg(‘x0200/00070/O/01/01234567890/09876543210//3/53686F7274204D657373616765/D9x03’) 00/00070/O/01/01234567890/09876543210//3/53686F7274204D657373616765/D9
Now we create a numeric message ‘716436383334’
>>> print UcpMsg(o_r=“O”, ot=01, adc=“0888444”, mt=2, nmsg=“716436383334”) 00/00041/O/01/0888444///2/716436383334/C5
>>> print UcpMsg(‘x0200/00041/O/01/0888444///2/716436383334/C5x03’) 00/00041/O/01/0888444///2/716436383334/C5
Response
Positive Result
>>> print UcpMsg(o_r=“R”, ot=01, trn=6, ack=“A”, sm=“01234567890:090196103258”) 06/00043/R/01/A/01234567890:090196103258/4E
>>> print UcpMsg(‘x0206/00043/R/01/A/01234567890:090196103258/4Ex03’) 06/00043/R/01/A/01234567890:090196103258/4E
Negative Result
>>> print UcpMsg(o_r=“R”, ot=01, trn=12, nack=“N”, ec=2) 12/00022/R/01/N/02//03
>>> print UcpMsg(‘x0212/00022/R/01/N/02//03x03’) 12/00022/R/01/N/02//03
Type 02 messages
