Optimized short message transport
A method for transferring data using optimized short message transport includes receiving at a first network node an attach request message. The attach request message includes short-message data. The first network node receives from a second network node a short-message data response message. The short-message data response message includes at least one of an address for a short message service center, an indication that indicates no mobile-terminated message is pending for the UE, or a short-message entity destination address.
1. A method, comprising:
transmitting, from a network node of a network, an indication to a user equipment (UE) indicating that the network supports optimized short message transport, wherein optimized short message transport comprises transmitting data in short messages using a registration procedure; and
receiving, at the network node and from the UE, a request message to register with the network, wherein the request message indicates that the request message is for cellular Internet of Things (CIoT) data transmission, and the request message includes a data message container.
2. The method of claim 1 , wherein the data message container includes one or more Protocol Data Units (PDUs) that are at least one of a short-message service (SMS)-SUBMIT PDU, an SMS-COMMAND PDU, an SMS-DELIVER-REPORT PDU, or an SMS-SUBMIT-REPORT PDU.
3. The method of claim 1 , wherein the request message indicates a type of service for CIoT data transmission.
4. The method of claim 1 , wherein the request message indicates that the UE requests not to transition to a connected mode.
5. The method of claim 1 , further comprising:
transmitting, from the network node, a response message to the UE, wherein the response message indicates whether a mobile-terminated message is pending for the UE.
6. The method of claim 1 , wherein the data message container includes CIoT data.
7. The method of claim 1 , wherein the request message is transmitted by the UE in response to receiving the indication.
8. The method of claim 1 , wherein the indication is transmitted explicitly via a broadcast message or implicitly based on a radio access technology (RAT) used by the network.
9. A network node, comprising:
at least one hardware processor; and
a non-transitory computer-readable storage medium coupled to the at least one hardware processor and storing programming instructions for execution by the at least one hardware processor, wherein the programming instructions, when executed, cause the network node to perform operations comprising:
transmitting an indication to a user equipment (UE) indicating that a network comprising the network node supports optimized short message transport, wherein optimized short message transport comprises transmitting data in short messages using a registration procedure; and
receiving, from the UE, a request message to register with the network, wherein the request message indicates that the request message is for cellular Internet of Things (CIoT) data transmission, and the request message includes a data message container.
10. The network node of claim 9 , wherein the request message is transmitted by the UE in response to receiving the indication.
11. The network node of claim 9 , wherein the data message container includes CIoT data.
12. The network node of claim 11 , wherein the CIoT data is one or more Protocol Data Units (PDUs) that are at least one of a short-message service (SMS)-SUBMIT PDU, an SMS-COMMAND PDU, an SMS-DELIVER-REPORT PDU, or an SMS-SUBMIT-REPORT PDU.
13. The network node of claim 9 , wherein the request message indicates a type of service for CIoT data transmission.
14. The network node of claim 9 , wherein the request message indicates that the UE requests not to transition to a connected mode.
15. The network node of claim 9 , the operations further comprising: transmitting a response message to the UE, wherein the response message indicates whether a mobile-terminated message is pending for the UE.
16. The network node of claim 9 , wherein the indication is transmitted explicitly via a broadcast message or implicitly based on a radio access technology (RAT) used by the network.
17. A non-transitory computer-readable medium storing instructions which, when executed, cause a computing device to perform operations comprising:
transmitting, from a network node of a network, an indication to a user equipment (UE) indicating that the network supports optimized short message transport, wherein optimized short message transport comprises transmitting data in short messages using a registration procedure; and
receiving, at the network node and from the UE, a request message to register with the network, wherein the request message indicates that the request message is for cellular Internet of Things (CIoT) data transmission, and the request message includes a data message container.
18. The non-transitory computer-readable medium of claim 17 , wherein the request message is transmitted by the UE in response to receiving the indication.
19. The non-transitory computer-readable medium of claim 17 , wherein the data message container includes CIoT data.
20. The non-transitory computer-readable medium of claim 19 , wherein the CIoT data is one or more Protocol Data Units (PDUs) that are at least one of a short-message service (SMS)-SUBMIT PDU, an SMS-COMMAND PDU, an SMS-DELIVER-REPORT PDU, or an SMS-SUBMIT-REPORT PDU.
21. The non-transitory computer-readable medium of claim 17 , wherein the request message indicates a type of service for CIoT data transmission.
22. The non-transitory computer-readable medium of claim 17 , wherein the request message indicates that the UE requests not to transition to a connected mode.
23. The non-transitory computer-readable medium of claim 17 , wherein the indication is transmitted explicitly via a broadcast message or implicitly based on a radio access technology (RAT) used by the network.
