Content for TS 29.337 Word version: 17.0.0
1 Scope p. 6
The present document describes the Diameter based interface between the Machine Type Communications-InterWorking Function (MTC-IWF) and the Short Message Service-Service Centre (SMS-SC) for communications with packet data networks and applications.
This specification defines the Diameter application for the T4 reference point between the MTC-IWF and the SMS-SC. The interactions between the MTC-IWF and the SMS-SC are specified.
MTC-IWF and SMS-SC (SMS-IWMSC) may also support the Diameter application for the SGd reference point to exchange SGd-OFR and SGd-OFA commands via T4. The stage 3 description for the SGd Diameter application is specified in TS 29.338.
The stage 2 description for communications with packet data networks and applications (architecture and functionality) is specified in the TS 23.682.

4 General Description p. 7
The T4 reference point between the MTC-IWF and the SMS-SC is an intra PLMN interface, as defined in the TS 23.682.
This document describes the T4 interface related procedures, message parameters and protocol specifications.
The T4 interface allows transfer of device trigger from MTC-IWF to SMS-SC inside HPLMN domain, along with the serving SGSN/MME/MSC/SMSF identities, and allows SMS-SC to report to MTC-IWF the submission outcome of a device trigger and the success or failure of delivering the device trigger to the UE.
