Abstract: A method of managing network resources across a broadband access network. A slice of the total available network resources is allocated to an application service provider, where the service provider utilises said slice to provide one or more services to a multiplicity of client devices. Traffic is monitored in a transport layer of the broadband access network to determine one or more parameters indicative of traffic flow. Said parameter(s) are passed to the application layer at an application layer end point of the application service. The parameter(s) are used at the application layer to manage traffic specific to the services and achieve efficient use of said slice.

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.

Abstract: A method and network node of a radio network, for enabling a User Equipment (UE) to save power in radio communication with the network node. The network node sets a waiting threshold for the UE and communicates data with the UE over a radio link. The network node also obtains traffic characteristics pertaining to the radio communication, and predicts a waiting time until next data is to be communicated with the UE based on the traffic characteristics. The network node further triggers the UE to enter a Discontinuous Reception (DRX) sleep when the predicted waiting time is longer than the waiting threshold. Thereby, power can be saved in the UE by immediately going to sleep after the last data.

Abstract: A technique for operating a media distribution network is presented. In the media distribution network media data are transmitted via an access network in media bursts to a media client. Each media burst is followed by an idle period in which no media data are transmitted.

The control message may be indicative of a load status of the access network, and the adjustment may be performed taking into account that load status.
