摘要： A method at a power-limited computing station for communicating in an intelligent transport system, the method including operating the computing station in one of a non-critical radio operating state and a safety-critical radio operating state; receiving a trigger at the computing station; determining whether the trigger should cause the computing station to transition a radio operating state; and if the trigger should cause the computing station to transition the radio operating state, changing the radio operating state to the other of the non-critical radio operating state and the safety-critical radio operating state.

摘要： In some examples, a configurator device maps a configuration attribute received from a wireless device to a credential attribute, the credential attribute to be mapped to a network policy. The configurator device sends the credential attribute to the wireless device, the credential attribute useable by the wireless device to access an access point (AP), and useable by the AP to obtain the network policy to apply to a communication of the wireless device.
