Abstract: A method is carried out by a network node of a telecommunication network for deciding whether to change the state of a communication channel to a communication terminal. A characteristic of the traffic associated with the terminal is determined based on data collected in the network over a first time interval of length L. Then, based on the traffic characteristic, the traffic activity expected to be associated with the terminal during at least a second time interval of length L is predicted. The second time interval follows the first time interval. The network node then decides, based on the predicted traffic activity for the second time interval, whether to change the state of the communication channel. The invention also relates to a network node or set of network nodes for carrying such a method. The invention further relates to computer programs and computer program products.
