23.3.7 Procedure in the IP-SM-GW

29.0023GPPMobile Application Part (MAP) specificationRelease 17TS

Process MT_SM_IPSMGW sheet 3: After unsuccessful delivery via the S-CSCF the IP-SM-GW may retry delivery via MSC and/or SGSN if MSC address and/or SGSN address are available (unless the reported error was "memory capacity exceeded" in which case a retry shall not be done). If the retry is successful, a positive response is returned to the SMS-GMSC. If the retry is unsuccessful, an error indication is returned to the SMS-GMSC as follows:
If one of the error indications received from S-CSCF, MSC, or SGSN is AbsentsSubscriberSM or UnidentifiedSubscriber, this error shall be returned to the SMS-GMSC.

Process MT_SM_IPSMGW sheet 3: The IP-SM-GW invokes the macro Report_SM_Delivery_Stat_IPSMGW if:

– the reason for failure to deliver the message is absent subscriber_SM, unidentified subscriber or SM delivery failure with error cause "MS memory capacity exceeded", and the SC address is not yet included in the MWD set, or

– the reason for failure to deliver the message is absent subscriber_SM, unidentified subscriber or SM delivery failure with error cause MS memory capacity exceeded, and the corresponding flag in the HLR (as indicated in the information received in the MAP_INFORM_SERVICE_CENTRE) is not set, or

– the reason for failure to deliver the message is absent subscriber_SM and the absent subscriber diagnostic is different from the absent subscriber diagnostic received in the MAP_INFORM_SERVICE_CENTRE.

The mobile terminated short message transfer process in the IP-SM-GW is shown in figure 23.3/15.
