Method and system for wireless road side units
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.
1. A method at a computing device within an Intelligent Transportation System, the method comprising:
detecting a traffic event at the computing device;
determining no fixed roadside unit is available from the computing device;
upon determining that no fixed roadside unit is available, establishing an Internet Protocol connection from the computing device to a network node;
sending a traffic event message from the computing device to the network node, the traffic event message providing information for the traffic event;
based on the sending, receiving a reconfiguration message, the reconfiguration message reconfiguring at least one of: traffic event parameters; traffic event reporting frequency; authentication parameters; authorization parameters; an address of the network node; or enabling or disabling the sending of traffic events; and
sending a second traffic event message, the second traffic event message being configured based on the reconfiguration message.
2. The method of claim 1 , wherein the detecting is based on parameters provisioned at the computing device.
3. The method of claim 1 , wherein the detecting is based on a Basic Safety Message received from a second computing device.
4. The method of claim 1 , wherein the determining no fixed roadside unit is available is based on a message from the fixed roadside unit indicating the fixed roadside unit has no capacity for further messages.
5. The method of claim 1 , wherein the determining no fixed roadside unit is available is based on a configuration parameter at the computing device.
6. The method of claim 1 , wherein the configuration message contains traffic event parameters, the traffic event parameters defining which traffic events to send a traffic event message for.
7. The method of claim 1 , wherein the detecting uses a first radio technology and the sending uses a second radio technology.
8. The method of claim 1 , wherein the network node is a traffic management gateway.
9. A computing device within an Intelligent Transportation System, the computing device comprising:
a processor; and
a communications subsystem,
wherein the computing device is configured to:
detect a traffic event at the computing device;
determine no fixed roadside unit is available from the computing device;
upon determining that no fixed roadside unit is available, establish an Internet Protocol connection from the computing device to a network node;
send a traffic event message from the computing device to the network node, the traffic event message providing information for the traffic event;
based on the sending, receive a reconfiguration message, the reconfiguration message reconfiguring at least one of: traffic event parameters; traffic event reporting frequency; authentication parameters; authorization parameters; an address of the network node; or enabling or disabling the sending of traffic events; and
send a second traffic event message, the second traffic event message being configured based on the reconfiguration message.
10. The computing device of claim 9 , wherein the computing device is configured to detect based on parameters provisioned at the computing device.
11. The computing device of claim 9 , wherein the computing device is configured to detect based on a Basic Safety Message received from a second computing device.
12. The computing device of claim 9 , wherein the computing device is configured to determine no fixed roadside unit is available based on a message from the fixed roadside unit indicating the fixed roadside unit has no capacity for further messages.
13. The computing device of claim 9 , wherein the computing device is configured to determine no fixed roadside unit is available based on a configuration parameter at the computing device.
14. The computing device of claim 9 , wherein the configuration message contains traffic event parameters, the traffic event parameters defining which traffic events to send a traffic event message for.
15. The computing device of claim 9 , wherein the computing device is configured to detect using a first radio technology and send using a second radio technology.
16. The computing device of claim 9 , wherein the network node is a traffic management gateway.
17. A non-transitory computer readable medium for storing instruction code which, when executed by a processor of a computing device within an Intelligent Transportation System cause the computing device to:
detect a traffic event at the computing device;
determine no fixed roadside unit is available from the computing device;
upon determining that no fixed roadside unit is available, establish an Internet Protocol connection from the computing device to a network node;
send a traffic event message from the computing device to the network node, the traffic event message providing information for the traffic event;
based on the sending, receive a reconfiguration message, the reconfiguration message reconfiguring at least one of: traffic event parameters; traffic event reporting frequency; authentication parameters; authorization parameters; an address of the network node; or enabling or disabling the sending of traffic events; and
send a second traffic event message, the second traffic event message being sent based on the reconfiguration message.
