An application device exchanges application data via a cellular radio communication network with an application server. The application device has a memory providing write access for a control entity associated with the network. The application device receives an information element from a network management node operated by the control entity. The information element is indicative of regulation information that defines at least one time span or point in time that can be used for transmission of application exchange data between the application device and the application server. The application device receives an instruction from the network management node to store the regulation information in the device memory, and stores the regulation information. The application device subsequently initiates transmission of the application exchange data between the application device and the application server only at an allowed time that is in accordance with the stored regulation information.
