Abstract

Examples described relate to using Session Initiation Protocol (SIP) notifications for Internet of Things (IoT). In an example, in response to an event on a first device in an Internet of Things (IoT) network, the first device may send an event request Uniform Resource Identifier (URI) to a hub device. In response to the event request URI, the first device may receive an event response URI corresponding to a second device in the IoT network from the hub device. The first device may transmit an out-of-dialog Session Initiation Protocol (SIP) notification for the event to the second device.

Claims

1. A method, executable by a processor, the method comprising:

in response to an event on a first device in an Internet of Things (IoT) network, sending from the first device, an event request Uniform Resource Identifier (URI) to a hub device;

responsive to the event request URI, receiving, at the first device, an event response URI corresponding to a second device in the IoT network from the hub device; and

transmitting via the first device, an out-of-dialog Session Initiation Protocol (SIP) notification corresponding to the event to the second device.

2. The method of claim 1, further comprising:

in response to the out-of-dialog SIP notification, receiving at the first device, a response from the second device.

3. The method of claim 1, further comprising:

responsive to the event request URI, receiving at the first device, an event response URI corresponding to a third device in the IoT network from the hub device.

4. The method of claim 1, further comprising:

generating the out-of-dialog Session Initiation Protocol (SIP) notification corresponding to the event.

5. The method of claim 1, wherein the out-of-dialog SIP notification corresponding to the event generates an action on the second device, wherein the action is specific to the second device.

6. An Internet of Things (IoT) device, the device comprising:

an identification engine to identify an event on the IoT device;

an event engine to send an event request Uniform Resource Identifier (URI) to a hub device in response to the event;

a receipt engine to receive an event response URI of a second IoT device from the hub device in response to the event request URI; and

a notification engine to transmit an out-of-dialog Session Initiation Protocol (SIP) notification corresponding to the event to the second IoT device.

7. The IoT device of claim 6, wherein the event request URI comprises of an event name and a domain name of the IoT device.

8. The IoT device of claim 6, wherein the event response URI comprises of an event name and a domain name corresponding to the second IoT device.

9. The IoT device of claim 6, wherein the event is generated by a sensor.

10. The IoT device of claim 6, wherein the receipt engine receives a respective event response URI corresponding to a plurality of IoT devices in response to the event request URI.

11. A non-transitory machine-readable storage medium comprising instructions, the instructions executable by a processor to:

send an event request Uniform Resource Identifier (URI) to a hub device from an Internet of Things (IoT) device in response to an event on the IoT device;

receive at the IoT device, a respective event response URI corresponding to a plurality of IoT devices in response to the event request URI;

transmit from the IoT device, a respective out-of-dialog Session Initiation Protocol (SIP) notification corresponding to the event to each of the IoT devices in the plurality of IoT devices; and

receive at the IoT device, a respective acknowledgement from each of the IoT devices in response to the respective out-of-dialog SIP notification.

12. The storage medium of claim 11, wherein the respective event response URI of the plurality of IoT devices is predefined for the event request URI.

13. The storage medium of claim 11, further comprising instructions to generate the respective out-of-dialog Session Initiation Protocol (SIP) notification corresponding to the event for each of the IoT devices.

14. The storage medium of claim 11, wherein the respective out-of-dialog SIP notification generates a respective action on each of the IoT devices.

15. The storage medium of claim 14, wherein the respective action on each of the IoT devices is predefined.
