After completing operation 2, SMS-IWMSC could check whether SMS interworking agreement exists or not based on IMSI. In this Figure 18g case, there is no SMS Interworking agreement between operators.

If SMS-IWMSC receives an informSC Message, then this message shall be ignored by the SMS-IWMSC.

If a failure report is indicated by the HLR after invocation of the "sendRoutingInfoForShortMsg" operation, the SMS-IWMSC shall return the appropriate error information to the MSC/SGSN with the error cause coded as follows:

Table 10.2-1

Return error from SendRoutingInfoForSM	Error mapping to ForwardShortMessage
system Failure	system Failure
data Missing	system Failure
Unexpected Data Value	system Failure
facility Not supported	SM Delivery Failure cause: invalid SME-address
unknown Subscriber	SM Delivery Failure cause: invalid SME-address
teleservice Not provisioned	SM Delivery Failure cause: invalid SME-address
Call barred	SM Delivery Failure cause: invalid SME-address
Absent Subscriber SM	SM Delivery Failure cause: invalid SME-address

Operation 2:

sendRoutingInfoForShortMsg. The operation is an interrogation of the HLR by the SMS-IWMSC to retrieve information necessary to forward the short message.

The outcome of the operation comprises either success, where the result contains the IMSI for terminated UE, or failure, which may be caused by several reasons.

Operation 7:

Message transfer MS → MSC or MS → SGSN.

The operation is used to transfer a short message from the MS to the MSC or to the SGSN.

Operation 8:

sendInfoForMO-SMS.

The operation provides a means for the MSC to verify from the VLR that the mobile originated short message transfer does not violate supplementary services invoked or restrictions imposed using the network feature Operator Determined Barring.

A successful VLR response carries the MSIsdn of the originating MS being transferred to the SC at SM-RL.

Operation 9:

forwardShortMessage.

The operation provides a means for the MSC or for the SGSN to transfer a short message to the SMS-IWMSC.

The procedure is required if the serving MSC or SGSN cannot access the SC directly, e.g. because it has no connection to SC (see clause 5).

The procedure works in tandem with the forwarding of the short message from the SMS-IWMSC to the SC. Thus, the outcome of the operation comprises either success, i.e. that the message has been delivered to the SC; or a failure that may be caused by several reasons, e.g. failure in the transfer MSC → SMS-IWMSC or SGSN → SMS-IWMSC, SC does not comply.

Operation 10:

Message transfer SMS-IWMSC → SC.

The operation is used to transfer a short message from an SMS-IWMSC to an SC, and consists of:

the transfer of a message containing the TPDU from the SMS-IWMSC to the SC (see "10a. Message transfer" in Figure 18); and
the return of either a "Failure report" (see 10c. in Figure 18) or a "Delivery report" (see 10b. in Figure 18).

"Failure report" is returned to the MS when the SMS-IWMSC has received indication from the network or the SC that the procedure was unsuccessful.
