between  MTC-IWF  and  SMS-SC

specified from  Rel-11
in  TS 23.682  and  TS 29.337 

The T4 reference point is used between the MTC-IWF and the SMS-SC to transfer device trigger to the SMS-SC inside the HPLMN.

Commands:
  • DTR/DTA:  Device-Trigger-Request/Answer
  • DRR/DRA:  Device-Report-Request/Answer
See also  RFC 6733  for Diameter Base Protocol, and  TS 29.230  for 3GPP-specific Diameter codes and identifiers.

between  MTC-IWF  and  SCS 

specified from  Rel-11
in  TS 23.682  and  TS 29.368 

The Tsp reference point is used between the MTC-IWF and the Services Capability Server (SCS) to invoke specific functionalities in the PLMN such as device triggering.

This interface is a PLMN internal interface if the SCS is controlled by the operator.

Commands:
  • DAR/DAA:  Device-Action-Request/Answer
  • DNR/DNA:  Device-Notification-Request/Answer
See also  RFC 6733  for Diameter Base Protocol, and  TS 29.230  for 3GPP-specific Diameter codes and identifiers.
