Abstract
A method at a computing device within an Intelligent Transportation System, the method including detecting a traffic event at the computing device; determining no fixed roadside unit is available from the computing device; establishing an Internet Protocol connection from the computing device to a network node; and sending a traffic event message from the computing device to the network node, the traffic event message providing information for the traffic event.
Claims20
A method at a network node within an Intelligent Transportation System, the method comprising:
- receiving traffic event messages at the network node from each of a plurality of computing devices, each traffic event message providing information for a traffic event;
- determining that reporting parameters for a first computing device from among the plurality of computing devices needs to be changed based on a time duration since a last report was received about the traffic event;
- based on the determining, sending a reconfiguration message to the first computing device reconfiguring at least one of traffic event parameters and traffic reporting frequency, the traffic event parameters defining which conditions on a road that may affect traffic behavior to send a traffic event message for;
- and
- receiving a second traffic event message from the first computing device, the second traffic event message being configured based on the reconfiguration message.
A network node within an Intelligent Transportation System, the network node comprising:
- a processor;
- and
- a communications subsystem, wherein the network node is configured to:
- receive traffic event messages from each of a plurality of computing devices, each traffic event message providing information for a traffic event;
- determine that reporting parameters for a first computing device from among the plurality of computing devices needs to be changed based on a time duration since a last report was received about the traffic event;
- based on the determination, send a reconfiguration message to the first computing device, the reconfiguration message reconfiguring at least one of traffic event parameters and traffic event reporting frequency, the traffic event parameters defining which conditions on a road that may affect traffic behavior to send a traffic event message for;
- and
- receive a second traffic event message from the first computing device, the second traffic event message being configured based on the reconfiguration message.
A non-transitory computer readable medium for storing instruction code which, when executed by a processor of a network node within an Intelligent Transportation System cause the network node to:
- receive traffic event messages from each of a plurality of computing devices, each traffic event message providing information for a traffic event;
- determine that reporting parameters for a first computing device from among the plurality of computing devices needs to be changed based a time duration since a last report was received about the traffic event;
- based on the determination, send a reconfiguration message to the first computing device, the reconfiguration message reconfiguring at least one of traffic event parameters and traffic reporting frequency, the traffic event parameters defining which conditions on a road that may affect traffic behavior to send a traffic event message for;
- and
- receive a second traffic event message from the first computing device, the second traffic event message being configured based on the reconfiguration message.
