Abstract: A method for processing messages in a data processing device, a data processing device and a computer program product. The device comprises a data transmission unit and a processing unit configured to control the processing of the received data in the decoding stack based on the decoding of the received data performed in the decoding layers, the decoding stack comprising at least a lower decoding layer and an upper decoding layer. The processing unit is further configured to form the decoding stack such that at least one decoding layer comprises two or more decoding layers based on different protocols and at least one switching element, and is configured to detect a control command for controlling the processing of data in the decoding stack, and the switching element is configured to control the processing of data in the decoding stack on the basis of the detected control command.
