B.1.1 MO-SMS

B.1.1.1 ConnectSMS operation

The Short Message TPDU is carried by a Short Message RPDU. The RPDU between the MSC or SGSN and the SMS-IWMSC is conveyed in the MAP MO-ForwardSM OPERATION. The MSC or SGSN shall obtain information from CAP OPERATION ConnectSMS and place it in MAP OPERATION MO-ForwardSM.

Table B.1

CAP ConnectSMS	MAP MO-ForwardSM ARGUMENT
CallingPartysNumber	sm-RP-OA; CHOICE set to msisdn
DestinationSubscriberNumber	sm-RP-UI; TP-Destination-Address
SMSCAddress	sm-RP-DA; CHOICE set to serviceCentreAddressDA

NOTE The encoding of "SignalInfo" in MO-ForwardSM is specified in 3GPP TS 23.040 [6].

B.1.1.2 EventReportSMS operation

The MSC or SGSN may receive error information from the SMS-IWMSC, via the MAP OPERATION MO-ForwardSM ERROR. The MSC or SGSN shall obtain the error information from MAP OPERATION MO-ForwardSM and place it in the CAP OPERATION EventReportSMS.

B.1.2 MT-SMS

B.1.2.1 InitialDPSMS operation (MT-SMS)

The Short Message TPDU is carried by a Short Message RPDU. The RPDU between the SMS-GMSC and the MSC or SGSN is conveyed in the MAP MT-ForwardSM OPERATION ARGUMENT. The MSC or SGSN shall obtain information from the MT-ForwardSM MAP Message and place it in CAP InitialDPSMS.

Table B.3

CAP InitialDPSMS	MAP MT-ForwardSM ARGUMENT
CallingPartysNumber	TP-Originating-Address from SMS-Deliver-TPDU. SMS-Deliver-TPDU is contained in sm-RP-UI.
SMSCAddress	sm-RP-OA
TPShortMessageSpecificInfo	First OCTET of the TPDU. The TPDU is contained in sm-RP-UI.
TPProtocolIdentifier	TP-Protocol-Identifier of the TPDU. The TPDU is contained in sm-RP-UI.
TPDataCodingScheme	TP-Data-Coding-Scheme of the TPDU. The TPDU is contained in sm-RP-UI.
TPValidityPeriod	TP-Validity-Period of the TPDU. The TPDU is contained in sm-RP-UI.

NOTE The encoding of "SignalInfo" in MT-ForwardSM is specified in 3GPP TS 23.040 [6].

B.1.2.2 ReleaseSMS operation (MT-SMS)

When the MSC or SGSN receives the CAP ReleaseSMS operation, it shall return a RP-ERROR RPDU to the SMS-GMSC. The RP-ERROR RPDU between the MSC or SGSN and the SMS-GMSC is conveyed in the MAP MT-ForwardSM OPERATION ERROR.
