Abstract

A system information block (SIB) in a radio interface is dedicated to broadcast data intended for Internet of things (IoT) devices. The data can be associated with most any IoT service, such as but not limited to, a vehicle-to-vehicle (V2V) and/or vehicle-to-everything (V2X) service. In one aspect, data, associated with an event, that has been aggregated from one or more IoT devices located within a region can be analyzed to determine a geographical area where a message regarding the event (e.g., accident) is to be broadcast. Further, the message can be dynamically prioritized and/or customized to target a particular class of IoT devices (e.g., connected cars) by employing different message identifiers.

Claims

1. A system, comprising:

a processor; and

a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising;

receiving, from a user equipment, report data associated with an event,

based on an analysis of the report data, determining a geographical area where notification data related to the event is to be broadcast; and

facilitating a transmission of the notification data via an access point device that is determined to have a coverage area that comprises a portion of the geographical area, wherein the notification data is to be transmitted via a system information block that has been dedicated to transfer Internet of things service data.

2. The system of claim 1, wherein the user equipment comprises a connected vehicle and the Internet of things service data comprises vehicle-to-everything service data.

3. The system of claim 1, wherein the determining comprises determining the geographical area based on context data associated with a location of the user equipment.

4. The system of claim 3, wherein the context data comprises weather data indicative of a weather condition associated with the location.

5. The system of claim 1, wherein the user equipment is a first user equipment that is located within a region, the report data is first report data, and wherein the determining comprises determining the geographical area based on second report data associated with the event that has been received from a second user equipment located within the region.

6. The system of claim 1, wherein the determining comprises determining the geographical area based on category data indicative of a category of the event.

7. The system of claim 1, wherein the operations further comprise:

based on the analysis, determining class data indicative of a class of Internet of things devices for which the notification data is intended; and

based on the class data, selecting a message identifier for the notification data, wherein devices that do not belong to the class have been configured to ignore broadcast information that comprises the message identifier.

8. The system of claim 1, wherein the operations further comprise:

based on the analysis, determining priority data indicative of a priority associated with the transmission of the notification data; and

based on the priority data, selecting a message identifier for the notification data.

9. The system of claim 1, wherein the operations further comprise:

based on the analysis, determining latency data indicative of a latency attribute associated with the transmission of the notification data; and

based on the latency data, selecting a message identifier for the notification data.

10. The system of claim 1, wherein the report data comprise sensor data related to a sensor of the user equipment.

11. The system of claim 1, wherein the notification data is employable to control an operation of an internet of things device located within the geographical area and served by the access point device.

12. A method, comprising:

based on analyzing report data that is associated with an event and that has been received from a user equipment, selecting, by a system comprising a processor, a geographical area where a notification message related to the event is to be broadcast;

determining, by the system, a network device that serves an Internet of things device located within the geographical area; and

facilitating, by the system, a broadcast of the notification message via the network device, wherein the notification message is to be broadcast via a system information block that is reserved to transfer Internet of things service data.

13. The method of claim 12, further comprising:

based on analyzing the report data, determining, by the system, class data indicative of a class of Internet of things devices for which the notification message is intended; and

based on the class data, selecting, by the system, identifier data indicative of an identifier associated with the notification message, wherein devices that do not belong to the class have been configured to ignore broadcast information that comprises the identifier data.

14. The method of claim 12, further comprising:

based on analyzing the report data, determining, by the system, priority data indicative of a priority associated with the broadcast; and

based on the priority data, selecting, by the system, identifier data indicative of an identifier associated with the notification message.

15. The method of claim 12, further comprising:

based on analyzing the report data, determining, by the system, latency data indicative of a latency attribute associated with the broadcast; and

based on the latency data, selecting, by the system, identifier data indicative of an identifier associated with the notification message.

16. The method of claim 12, wherein the selecting the geographical area comprises selecting a region that has been determined to satisfy a proximity criterion associated with a location of the user equipment.

17. A machine-readable storage medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:

receiving, from a control plane device, alert data that has been generated based on report data received from a first internet of things device, wherein the report data is indicative of an event associated with the first internet of things device;

determining identifier data associated with the alert data; and

based on an analysis of the identifier data, facilitating a transfer of the alert data to a second internet of things device via a system information block that has been dedicated to transfer information associated with an Internet of things service.

18. The machine-readable storage medium of claim 17, wherein the operations further comprise:

based on the analysis, determining priority data indicative of a priority associated with the transfer; and

based on the priority data, prioritizing the transfer.

19. The machine-readable storage medium of claim 17, wherein the operations further comprise:

modifying a frequency of transmissions performed via the system information block.

20. The machine-readable storage medium of claim 17, wherein the facilitating comprises facilitating the transfer in response to determining that the identifier data specifies that the alert data is related to the Internet of things service.
