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.
