Abstract

Methods and systems are disclosed for automatically generating an events dictionary in an Internet of Things (IoT) network. In an aspect, a device receives a notification of an event from an IoT device, determines a state of the IoT device before and after the event, compares the states of the IoT device, determines a type of state change of the event, determines whether the type of the state change of the first event is present in the events dictionary, creates a generic entry based on the type of the state change of the first event not being present in the events dictionary, and stores, in the events dictionary, a mapping of an event description of the event to the generic entry.

First claim

What is claimed is:

1. A method of automatically generating an events dictionary in an Internet of Things (IoT) network, comprising:
receiving a notification of a first event from a first IoT device in the IoT network;
determining a state of the first IoT device before and after the first event;
comparing the states of the first IoT device;
determining a type of state change of the first event based on the comparing;
determining whether the type of the state change of the first event is present in the events dictionary;
creating a generic entry based on the type of the state change of the first event not being present in the events dictionary, wherein the type of the state change associated with the generic entry is common to IoT devices of a same type and/or class as the first IoT device; and
storing, in the events dictionary, a mapping of an event description of the first event to the generic entry.

2. The method of claim 1 ,
wherein determining the state of the first IoT device before the first event includes periodically polling the first IoT device to retrieve the state of the first IoT device before the first event, and
wherein determining the state of the first IoT device after the first event includes retrieving the state of the first IoT device after the first event.

3. The method of claim 1 , further comprising:
determining a type of the first IoT device, wherein the creating comprises creating the generic entry in the events dictionary for a type of IoT device matching the type of the first IoT device and a type of state change matching the type of the state change of the first event.

4. The method of claim 1 , wherein the generic entry comprises an enumeration and a text description of the type of the state change associated with the generic entry.

5. The method of claim 1 , further comprising:
receiving a second notification of a second event by a second IoT device in the IoT network;
determining a state of the second IoT device before and after the second event;
comparing the states of the second IoT device;
determining a type of state change of the second event based on the comparing;
mapping the second event to the generic entry based on the second event being a same type of state change as the state change of the first event and a same type and/or class as the first IoT device; and
storing a mapping of an event description of the second event received from the second IoT device to the generic entry.

6. The method of claim 5 , wherein the event description of the second event is different from the event description of the first event.

7. The method of claim 5 , wherein the generic entry describes a generic state change that is common to the first IoT device and the second IoT device, and further wherein, the generic entry includes event descriptions for events received from the first IoT device and the second IoT device.

8. The method of claim 1 , further comprising:
transmitting the events dictionary to other IoT devices in the IoT network.

9. The method of claim 8 , further comprising:
defining home automation rules based on generic events defined in the events dictionary; and
distributing the home automation rules to the other IoT devices in the IoT network.

10. The method of claim 9 , wherein a third IoT device in the IoT network receives an event notification from the first or a second IoT device in the IoT network, maps event information in the received event notification to the generic entry in the events dictionary, and executes the home automation rules defined for the generic entry in the events dictionary.

11. An apparatus for automatically generating an events dictionary in an Internet of Things (IoT) network, comprising:
a transceiver configured to receive a notification of a first event from a first IoT device in the IoT network; and
at least one processor configured to:
determine a state of the first IoT device before and the first event;
compare the states of the first IoT device;
determine a type of state change of the first event based on the comparison of the states of the first IoT device;
determine whether the type of the state change of the first event is present in the events dictionary; and
create a generic entry based on the type of the state change of the first event not being present in the events dictionary, wherein the type of the state change associated with the generic entry is common to IoT devices of a same type and/or class as the first IoT device; and

a memory configured to store, in the events dictionary, a mapping of an event description of the first event to the generic entry.

12. The apparatus of claim 11 ,
wherein the at least one processor being configured to determine the state of the first IoT device before the first event includes the at least one processor being configured to periodically poll the first IoT device to retrieve the state of the first IoT device before the first event, and
wherein the at least one processor being configured to determine the state of the first IoT device after the first event includes the at least one processor being configured to retrieve the state of the first IoT device after the first event.

13. The apparatus of claim 11 , wherein the at least one processor is further configured to determine a type of the first IoT device, wherein the at least one processor being configured to create comprises the at least one processor being configured to create the generic entry in the events dictionary for a type of IoT device matching the type of the first IoT device and a type of state change matching the type of the state change of the first event.

14. The apparatus of claim 11 , wherein the generic entry comprises an enumeration and a text description of the type of the state change associated with the generic entry.

15. The apparatus of claim 11 ,
wherein the transceiver is further configured to receive a second notification of a second event broadcasted by a second IoT device in the IoT network;
wherein the at least one processor is further configured to:
determine a state of the second IoT device before and after the second event;
compare the states of the second IoT device;
determine a type of state change of the second event based on a comparison of the states of the second IoT device; and
map the second event to the generic entry based on the second event being a same type of state change as the state change of the first event and a same type and/or class as the first IoT device; and

wherein the memory is further configured to store a mapping of an event description of the second event received from the second IoT device to the generic entry.

16. The apparatus of claim 15 , wherein the event description of the second event is different from the event description of the first event.

17. The apparatus of claim 15 , wherein the generic entry describes a generic state change that is common to the first IoT device and the second IoT device, and further wherein, the generic entry includes event descriptions for events received from the first IoT device and the second IoT device.

18. The apparatus of claim 11 , wherein the transceiver is further configured to transmit the events dictionary to other IoT devices in the IoT network.

19. The apparatus of claim 18 ,
wherein the at least one processor is further configured to define home automation rules based on generic events defined in the events dictionary; and
wherein the transceiver is further configured to distribute the home automation rules to t
