摘要： A method and apparatus for transmitting a real-time media stream in a communications network. The method comprises separating an essential part of the media stream from a non-essential part of the media stream in said real-time media stream and transmitting the essential part of the media stream on a first bearer and the non-essential part of the media stream on a second bearer. Priority of the first bearer is higher than priority of the second bearer. The method also comprises performing adaptation of the essential part of the media stream in response to a change of traffic conditions on the second bearer.

摘要： A base station or other network node configures a network transmission in dependence on a directional scanning reception ability of a wireless communication device targeted by the transmission. An example transmission configuration is selecting or restricting which Transmission/Reception Point to use for the transmission or selecting or restricting the beamforming configuration to use for the transmission. The device complements operations in the wireless communication network by indicating its directional scanning reception ability in initial signaling, such as used for random access, or in Radio Resource Control signaling, or both.

摘要： The present disclosure relates to a computer-implemented method and an apparatus for classifying anomalies of one or more feature-associated anomalies in network data traffic between devices in a first part of a network and devices in a second part of the network. The method comprises retrieving at least one network data traffic sample and determining one or more feature-associated anomaly scores for the retrieved at least one network data traffic sample. The method further comprises determining feature importance of each feature of a feature-associated anomaly score and classifying one or more anomalies based on the determined one or more feature-associated anomaly scores and the determined feature importance.

摘要： A method and a corresponding runtime environment for migrating an instance of an actor of an application are provided. An initiating runtime environment performs a method comprising selecting, based on obtained security attributes for a set of target runtime environments, a target runtime environment from the set of target runtime environments for migration of the instance of the actor. The method comprises migrating the instance of the actor to the selected target runtime environment once the target runtime environment has been selected.

摘要： There is provided mechanisms for handling instances of a trusted execution environment on an execution platform. The trusted execution environment is associated with a secure cryptoprocessor. The secure cryptoprocessor holds a register. The trusted execution environment is configured to read from and write to a volatile part of the register at a given index i. A method is performed by the trusted execution environment. The method comprises checking, upon start of a new instance of the trusted execution environment, status of the register at the given index i. The method comprises enabling the new instance to keep running only when successfully reading a first value representing no currently run instance of the trusted execution environment from the register at the index i or if the register at the given index i has its status set to “undefined” when checking the status. The method comprises writing a second value representing one currently run instance of the trusted execution environment to the register at the given index i.

摘要： A method of a network node for changing a first frequency of a first original cell, wherein one or more wireless communication devices are served by the original cell, and wherein the network node controls a plurality of other cells. The method comprises selecting one or more second frequency of an unlicensed spectrum that the network node should switch the original cell to, determining a second cell on the selected one or more second frequency as target cell and causing the target cell to maintain the same neighbor cell relations as the original cell. The method also comprises moving the one or more wireless communication devices from the original cell to the target cell, turning off the original cell when the one or more wireless communication devices have been moved from the original cell to the target cell and informing one or more neighboring network nodes of the frequency change to the one or more second frequency. Also disclosed is a computer program product, an arrangement and a network node.

摘要： A wake-up radio unit for a wireless communication device is disclosed, wherein the wireless communication device has a plurality of wireless communication receivers. The wake-up radio unit is adapted to wake up any of the plurality of wireless communication receivers by receiving a wake-up signal, selecting one or more of the plurality of wireless communication receivers based on the wake-up signal, and waking up the selected one or more wireless communication receiver. In some embodiments, wherein each of the plurality of wireless communication receivers is adapted to receive in accordance with respective standard, the wake-up signal may comprise a set of symbols selected from a collection of possible sets of symbols. Each such set of symbols may indicate, at least in part, one or more corresponding standards. Then, the wake-up radio unit may be adapted to select one or more of the plurality of wireless communication receivers based on the wake-up signal by identifying the set of symbols of the received wake-up signal, and selecting the one or more wireless communication receivers adapted to receive in accordance with the one or more corresponding standards indicated by the identified set of symbols. Corresponding arrangement, wireless communication device, method and computer program product are also disclosed.
