Abstract: A network apparatus, such as a road side unit, measures signalling transmitted from vehicle devices, to obtain the status of road traffic in the proximity of the road side unit. If a pre-defined triggering event is detected in the status of the road traffic in the proximity of the road side unit, the road side unit transmits to a serving network node, a status report in order to report the obtained road traffic status to the serving network node. The road side unit receives from the serving network node, control signalling indicating at least one road side unit operation mode selected for communication, and sets the operation mode of the road side unit to correspond to the at least one selected road side unit operation mode for the communication.
