DATA TRAFFIC CONTROL

Controlling data traffic of a communication network managed by a network operator, NWO. The data traffic includes first and second type traffic. The second type traffic is between a data service provider and an end user device provided by the OEM, and the first type traffic is between the OEM and the end user device. A controller acquires one or more device-specific second type traffic consumption parameters of the end user device, causing a downlink data traffic restrictor of the NWO to restrict downlink second type traffic between the data service provider and the end user device in accordance with the one or more device-specific second type traffic consumption parameters, and causes an uplink data traffic restrictor of the end user device to restrict uplink second type traffic between the data service provider and the end user device in accordance with the device-specific second type traffic consumption parameters.
