1. An apparatus comprising:

  • logic for a machine type communication-interworking function (MTC-IWF), at least a portion of the logic in hardware, the logic to;

    receive a Device-Action-Request (DAR) command from a service capability server (SCS) through a telecommunications service provider (Tsp) interface, the DAR command including a Device-Action attribute value pair (AVP) having an user equipment (UE) identifier to indicate an UE to receive a trigger message initiated by the SCS, an SCS-Identity for the SCS, a Reference-Number to identify the trigger message and an Action-Type AVP set to a value to indicate a device trigger recall request to recall the trigger message;

    determine a status of the device trigger recall request responsive to one of an initiation of a recall procedure with a short message service-service center (SMS-SC) or a rejection of the initiation of the recall procedure by the MTC-IWF or by the SMS-SCS; and

    send a Device-Action-Answer (DAA) command to the SCS, the DAA command including a Device-Notification AVP having the UE identifier, the SCS-Identity, the Reference-Number, the Action-Type AVP and a Request-Status AVP set to a value to indicate success or failure of the device trigger recall request.
