Abstract

Embodiments of the present disclosure describe techniques and configurations for transmitting small data payloads such as, for example, Machine Type Communication (MTC) data in a wireless communication network. A system may include features to implement an interworking function (IWF) to receive, from a machine type communication (MTC) server, a trigger to send a data payload, which is smaller than a preconfigured threshold, to a user equipment (UE) over a wireless communication network, and send, over a first reference point to a first module including a Mobility Management Entity (MME) or a Serving GPRS (General Packet Radio Service) Support Node (SGSN) or a second reference point to a second module including a Home Location Register (HLR) or a Home Subscriber Server (HSS), the data payload and a request to forward the data payload to the UE.

Claims

1. An apparatus to implement a machine type communications interworking function (MTC-IWF), comprising:

a receiver of the MTC-IWF adapted to receive, over a first reference point from a services capability server (SCS), a device trigger request message comprising a trigger payload that is to be sent to a user equipment (UE) over a wireless communication network; and

a transmitter of the MTC-IWF adapted to send, over a second reference point to a Mobility Management Entity (MME) or a Serving General Packet Radio Service Support Node (SGSN), the trigger payload and a request to forward the trigger payload to the UE; and

a processor adapted to authorize the SCS before communication is established with the wireless communication network and to authorize control plane requests from the SCS,

wherein the MTC-IWF is configured to terminate the first reference point and the second reference point, hide internal public land mobile network (PLMN) topology, and relay or translate signaling protocols used over the first reference point to invoke specific functionality in the PLMN.

2. The apparatus of claim 1, wherein the MME or the SGSN is configured to send, to a base station of the wireless communication network, a paging message that includes a small data indicator that indicates a location of the trigger payload to be forwarded to the UE.

3. The apparatus of claim 2, wherein the MME is configured to send a paging message that includes the small data indicator to the base station, the small data indicator indicating that the trigger payload is at the MME.

4. The apparatus of claim 1, wherein the authorizing the SCS before communication is established, is to indicate that the MTC-IWF is to authenticate the SCS before control plane requests from the SCS are authorized.

5. The apparatus of claim 1, wherein the MME is configured to page the UE if the UE is in idle mode.

6. A method comprising:

receiving, by an apparatus to implement a machine type communications interworking function (MTC-IWF) over a first reference point from a services capability server (SCS), a device trigger request message comprising a trigger payload that is to be sent to a user equipment (UE) over a wireless communication network; and

sending, over a second reference point to a Mobility Management Entity (MME) or a Serving General Packet Radio Service Support Node (SGSN), the trigger payload and a request to forward the trigger payload to the UE, wherein the apparatus is configured to authorize the SCS before communication is established with the wireless communication network and to authorize control plane requests from the SCS,

wherein the MTC-IWF is configured to terminate the first reference point and the second reference point, hide internal public land mobile network (PLMN) topology, and relay or translate signaling protocols used over the first reference point to invoke specific functionality in the PLMN.

7. The method of claim 6, further comprising:

sending, by the MME or the SGSN to a base station of the wireless communication network, a paging message that includes a small data indicator that indicates a location of the trigger payload to be forwarded to the UE.

8. The method of claim 7, further comprising:

sending, by the MME, a paging message that includes the small data indicator to the base station, the small data indicator indicating that the trigger payload is at the MME.

9. The method of claim 6, further comprising:

authorizing, by the apparatus, the SCS before communication is established to indicate that the MTC-IWF is to authenticate the SCS before control plane requests from the SCS are authorized.

10. The method of claim 6, further comprising:

paging, by the MME, the UE if the UE is in idle mode.

11. One or more non-transitory computer readable media having instructions that, when executed by one or more processors, cause a machine type communications interworking function (MTC-IWF) to:

receive, over a first reference point by the MTC-IWF from a services capability server (SCS), a device trigger request message comprising a trigger payload that is to be sent to a user equipment (UE) over a wireless communication network; and

send, over a second reference point by the MTC-IWF to a Mobility Management Entity (MME) or a Serving General Packet Radio Service Support Node (SGSN), the trigger payload and a request to forward the trigger payload to the UE, wherein the MTC-IWF is configured to authorize the SCS before communication is established with the wireless communication network and to authorize control plane requests from the SCS,

wherein the MTC-IWF is configured to terminate the first reference point and the second reference point, hide internal public land mobile network (PLMN) topology, and relay or translate signaling protocols used over the first reference point to invoke specific functionality in the PLMN.

12. The one or more computer readable media of claim 11, wherein the instructions when executed further cause the MTC-IWF to:

authorize the SCS before communication is established to indicate that the MTC-IWF is to authenticate the SCS before control plane requests from the SCS are authorized.
