|Publication Date:||1 April 2022|
The present document describes the Diameter based interface between the Machine Type Communications-Inter
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 3GPP TS 29.338 .
The stage 2 description for communications with packet data networks and applications (architecture and functionality) is specified in the 3GPP TS 23.682 .
