A method to indicate a delivery status of a device trigger message and a trigger payload, comprising:

• transmitting, by a user equipment (UE) adapted for machine type communication MTC) in a public land mobile network (PLMN), a message to indicate reception of the device trigger message and the trigger payload, the message being transmitted to a node comprising a mobile management entity (MME) or a Serving General Packet Radio Service Support Node (SGSN) adapted to receive a trigger notification from an MTC interworking function (MTC-IWF) over a T5 reference point, wherein the trigger payload comprises a first data payload for a downlink transmission from an MTC server to the UE and information to cause transmission of a second data payload in an uplink transmission from the UE to the MTC server,
• wherein the MTC-IWF is adapted to:
• receive a trigger request over a Tsp reference point from the MTC server;
• wherein the trigger request comprises:
• a first container including a value to indicate a message type of the trigger request, and
• a second container including the trigger payload from the MTC server,
• and
• send, to the MTC server over the Tsp reference point, a trigger report to indicate a success or failure of the device trigger message to the UE, and
• send a trigger acknowledgement to the MTC server over;
• the Tsp reference point when the MTC-IWF is unable to process the trigger request;
• and
• initiating, by the UE, communication with the MTC server.

A method comprising:

• receiving, by a Machine Type Communication interworking function (MTC-IWF) over a Tsp reference point from a Machine Type Communication (MTC) server of a wireless communication network, a trigger request comprising a first container and a second container, wherein:
• the first container includes a value to indicate a message type of the trigger request, and
• the second container includes:
• a trigger to cause transmission of a first data payload in an uplink transmission from a user equipment (UE) to the MTC server, wherein the first data payload is smaller than a preconfigured threshold, and
• a second data payload for downlink transmission from the MTC server to the UE, wherein the second data payload is smaller than the preconfigured threshold,
• wherein the UE is adapted to wirelessly communicate with the wireless communication network via a GSM Enhanced Data for GSM Evolution (EDGE) Radio Access Network (GERAN), Universal Terrestrial Radio Access Network (UTRAN) or Evolved UTRAN (E-UTRAN), and wherein the first data payload and the second data payload are smaller than a preconfigured threshold;
• when the MTC-IWF is able to process the trigger request and in response to the trigger request, sending, over T5 reference point to a node including a Mobility Management Entity (MME) or a Serving General Packet Radio Service Support Node (SGSN), a trigger notification to trigger sending of the first data payload over the wireless communication network, wherein the trigger notification comprises the second data payload and the trigger:
• and
• when the MTC-IWF is unable to process the trigger request, sending, by the MTC-IWF to the MTC server over the Tsp reference point, a trigger acknowledgement indicating that the MTC-IWF was unable to process the trigger request;
• and
• sending, by the MTC-IWF to the MTC server over the Tsp reference point, a trigger report, wherein the trigger report is to indicate a success or failure of delivery of a message to the UE, wherein the message is to trigger sending the first data payload based on the trigger request.

An apparatus, comprising:

• one or more computer-readable media having instructions;
• and
• one or more processors coupled with the one or more computer-readable media, and the one or more processors are to execute the instructions to implement a first node including a Mobility Management Entity (MME) or a Serving General Packet Radio Service Support Node (SGSN) of a wireless communication network to:
• receive a trigger notification over a T5 reference point, the trigger notification comprising a first container and a second container, wherein:
• the first container includes a value to indicate a message type of a trigger request, and
• the second container includes a trigger to cause transmission of a first data payload in an uplink transmission from a user equipment (UE) to a Machine Type Communication (MTC) server over the wireless communication network, and a second data payload for downlink transmission from the MTC server to the UE, wherein the first data payload and the second data payload are smaller than a preconfigured threshold,
• wherein the node is to receive the trigger notification from an MTC interworking function (MTC-IWF) in response to receipt of a trigger request from the MTC server over a Tsp reference point, and the MTC-IWF is adapted to send a trigger acknowledgement to the MTC server over the Tsp reference point when the MTC-IWF is unable to process the trigger request, and the MTC-IWF is adapted to send a first trigger report to the MTC server over the Tsp reference point to indicate acceptance of the trigger notification;
• send, in response to receipt of the trigger notification, a message to indicate the trigger notification to the UE, wherein the message includes the trigger and the second data payload for downlink transmission from the MTC server to the UE, and
• wherein the UE is adapted to wirelessly communicate with the wireless communication network, the wireless communication network including a Global System for Mobile Communication (GSM), General Packet Radio Service (GPRS), Universal Mobile Telecommunications System (UMTS), High Speed Packet Access (HSPA), Evolved HSPA (E-HSPA), or Long-Term Evolution (LTE) network;
• and
• send, to the MTC-IWF, a second trigger report, wherein the trigger report is to indicate a success or failure of delivery of the message to the UE, and wherein the success or failure indicated by the second trigger report is to be included in the first trigger report.

An apparatus comprising:

• one or more computer-readable media having instructions;
• and
• one or more processors coupled with the one or more computer-readable media, wherein execution of the instructions is to cause a user equipment (UE) adapted for machine type communication (MTC) in a public land mobile network (PLMN) to indicate a delivery status of a device trigger message and a trigger payload, wherein, to indicate the delivery status, execution of the instructions is to cause the UE to:
• transmit a message to indicate reception of the device trigger message and the trigger payload, wherein transmission of the message is to a node comprising a mobile management entity (MME) or a Serving General Packet Radio Service Support Node (SGSN), wherein the trigger payload comprises a first data payload to be sent in a downlink transmission from a Services Capability Server (SCS) to the UE and information to cause transmission of a second data payload in an uplink transmission from the UE to the SCS,
