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.

First claim

What is claimed is:

1. A system, comprising:
a processor; and
a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
determining a geographical area related to an event associated with first user equipment;
broadcasting notification data related to the event via a system information block configured to transfer internet of things data;
configuring a second user equipment located within the geographical area to read the system information block; and
configuring a third user equipment located within the geographical area to ignore the system information block.

2. The system of claim 1 , wherein the broadcasting comprises broadcasting the notification data using an access point device associated with a coverage area that comprises a portion of the geographical area.

3. The system of claim 2 , wherein the configuring comprises configuring the second user equipment located within the geographical area and served by the access point device to read the system information block.

4. The system of claim 1 , wherein the broadcasting comprises broadcasting the notification data via a radio interface in a broadcast control channel.

5. The system of claim 1 , wherein the operations further comprise:
receiving, from the first user equipment, report data associated with the event.

6. The system of claim 5 , wherein the determining comprises determining the geographical area based on an analysis of the report data.

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

8. The system of claim 1 , wherein the determining comprises determining the geographical area based on weather data indicative of a weather condition associated with a location of the first user equipment.

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

10. The system of claim 1 , wherein the determining comprises determining the geographical area based on sensor data related to a sensor of the first user equipment.

11. The system of claim 1 , wherein the operations further comprise:
determining class data indicative of a class of internet of things devices for which the notification data is intended; and
selecting a message identifier for the notification data based on the class data.

12. A method, comprising:
determining, by a system comprising a processor, a geographical region related to an event associated with user equipment;
transmitting, by the system, a notification message related to the event via a system information block that is reserved for transferring internet of things data;
configuring, by the system, a first internet of things device located within the geographical region to read the system information block; and
configuring, by the system, a second internet of things device located within the geographical region to ignore the system information block.

13. The method of claim 12 , wherein the determining comprises determining the geographical region based on analyzing report data associated with the event.

14. The method of claim 12 , wherein the transmitting comprises transmitting the notification message via a network device that services the second internet of things device located within the geographical region.

15. The method of claim 12 , wherein the transmitting comprises transmitting the notification message via a radio interface in a broadcast control channel.

16. The method of claim 12 , further comprising:
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.

17. A non-transitory machine-readable storage medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:
determining a geographical area related to an event associated with a first internet of things device;
transmitting alert data related to the event via a system information block configured to transfer information associated with an internet of things service; and
configuring a second internet of things device located within the geographical area to be able to read the system information block; and
configuring a third internet of things device located within the geographical area to be unable to read the system information block.

18. The non-transitory machine-readable storage medium of claim 17 , wherein the transmitting comprise transmitting the alert data via a radio interface of a broadcast control channel.

19. The non-transitory 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 non-transitory machine-readable storage medium of claim 17 , wherein the transmitting comprises transmitting the alert data in response to determining that identifier data associated with the alert data specifies that the alert data is related to the second internet of things service.
