To reduce the maximum delays and the variation in the transmission times of call packets, control packets that contain signaling information on the data transmission network are separated from the call packets in the network node, information on the arrival rate of the call packets is maintained, the duration of the control packet that is to be sent next is calculated (22), and the interval to the reception of the next call packet is defined (23). The calculated duration is compared (24) with the defined interval, and if the duration is shorter than or equal to the interval, the control packet is transmitted immediately (25). If the duration is longer than the interval, the control packet is put (27) in a transmission queue, and transmitted immediately after the call packet is received.
