Universal Mobile Telecommunications System (UMTS); LTE; Diameter-based T4 Interface for communications with packet data networks and applications (V11.6.0; 3GPP TS 29.337 version 11.6.0 Release 11)
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. The stage 2 description for communications with packet data networks and applications (architecture and functionality) is specified in the 3GPP TS 23.682 [2].
