Abstract: The invention relates to a method, a device (101), a system (106), a computer program (504) and a computer program product (505) for supporting botnet traffic detection. A device (101) for supporting botnet traffic detection obtains information associated with a first data flow of a first communication device (104a) and information associated with a second data flow of the first communication device (104a) or of a second communication device (104b), and trains a first and a second prediction model. The first and second prediction models are applied to data traffic and a label based on the outputs of the first and the second prediction models is associated with the traffic, wherein the label either indicates benign traffic or malicious traffic.

Abstract: A method for an access point of a wireless communication network is disclosed. The access point is adapted to use a communication channel resource to communicate with a plurality of first wireless communication devices using orthogonal frequency division multiple access (OFDMA) and to communicate with a plurality of second wireless communication devices using carrier sense multiple access with collision avoidance (CSMA/CA). The communication channel resource comprises a bandwidth of frequencies, the bandwidth of frequencies being dividable into a plurality of sub-carriers for OFDMA and a part of the bandwidth of frequencies forming a primary channel for CSMA/CA. The method comprises transmitting a downlink packet over all frequencies of the bandwidth for triggering one or more of the first wireless communication devices to perform OFDMA based uplink transmission.

Abstract: The basic idea of the present invention is to let the base station enter a low-power, low-radiation cycle, the so called “sleep mode”, when there are no UEs using it and to introduce methods to “wake up” the base station from this state when there is a UE in the vicinity which is allowed to access the base station and which may need it on short notice.

Abstract: An end node in a packet-switched network is proposed wherein the end node is arranged to exchange packets consisting of a packet header and payload data with a server node connected to the packet-switched network. The end node includes at least one module adapted to extract quality of service parameter values from the headers of packets received over the packet-switched network and to insert the extracted quality of service parameter value in the headers of packets destined for transmission to the server node over the packet-switched network. In this manner the end node automatically adapts the quality of service parameters received over the packet-switched network to correspond with the type of quality of service defined in received packets. Such a system means that only the server node need be configured with the quality of service parameters applicable on the particular packet switched network, so greatly reducing the installation and configuration overheads in a multi-user network.

Abstract: An R.F. power amplifier circuit comprising a power control loop is described. The power control loop includes an R.F. power amplifier having a power control input and a power supply input as well as at least one feedback path coupled between the power control input and the power supply input of the power amplifier. The feedback path includes at least one variable loop element that has a control terminal configured to reduce variations of control loop parameters.
