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:
receiving, at a user equipment (UE), from a network, an indication indicating that the network supports optimized short message transport, wherein optimized short message transport comprises transmitting data in short messages using an attach procedure; and
transmitting, from the UE, an attach request message to the network, wherein the attach request message indicates that the attach request message is for cellular Internet of Things (CIoT) data transmission, and the attach 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 attach request message indicates a type of service for CIoT data transmission.
4. The method of claim 1 , wherein the attach request message indicates that the UE requests not to transition to a connected mode.
5. The method of claim 1 , further comprising:
receiving an attach response message, wherein the attach response message indicates whether there is a mobile-terminated message for the UE is pending.
6. The method of claim 1 , wherein the data message container includes CIoT data.
7. The method of claim 1 , wherein the attach request message is transmitted in response to receiving the indication.
8. A user equipment (UE), 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 UE to perform operations comprising:
receiving, from a network, an indication indicating that the network supports optimized short message transport, wherein optimized short message transport comprises transmitting data in short messages using an attach procedure; and
transmitting an attach request message to the network, wherein the attach request message indicates that the attach request message is for cellular Internet of Things (CIoT) data transmission, and the attach request message includes a data message container.
9. The UE of claim 8 , wherein the attach request message is transmitted in response to receiving the indication.
10. The UE of claim 8 , wherein the data message container includes CIoT data.
11. The UE of claim 10 , 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.
12. The UE of claim 8 , wherein the attach request message indicates a type of service for CIoT data transmission.
13. The UE of claim 8 , wherein the attach request message indicates that the UE requests not to transition to a connected mode.
14. The UE of claim 8 , the operations further comprising: receiving an attach response message, wherein the attach response message indicates whether there is a mobile-terminated message pending for the UE.
15. A non-transitory computer-readable medium storing instructions which, when executed, cause a computing device to perform operations comprising;
receiving, at a user equipment (UE), from a network, an indication indicating that the network supports optimized short message transport, wherein optimized short message transport comprises transmitting data in short messages using an attach procedure; and
transmitting, from the UE, an attach request message to the network, wherein the attach request message indicates that the attach request message is for cellular Internet of Things (CIoT) data transmission, and the attach request message includes a data message container.
16. The non-transitory computer-readable medium of claim 15 , wherein the attach request message is transmitted in response to receiving the indication.
17. The non-transitory computer-readable medium of claim 15 , wherein the data message container includes CIoT data.
18. The non-transitory computer-readable medium of claim 17 , 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.
19. The non-transitory computer-readable medium of claim 15 , wherein the attach request message indicates a type of service for CIoT data transmission.
20. The non-transitory computer-readable medium of claim 15 , wherein the attach request message indicates that the UE requests not to transition to a connected mode.
21. The method of claim 1 , wherein the indication is received explicitly via a broadcast message or implicitly based on a radio access technology (RAT) used by the network.
22. The UE of claim 8 , wherein the indication is received explicitly via a broadcast message or implicitly based on a radio access technology (RAT) used by the network.
23. The non-transitory computer-readable medium of claim 15 , wherein the indication is received explicitly via a broadcast message or implicitly based on a radio access technology (RAT) used by the network.
