摘要： A first example of a method according to an embodiment of the invention comprises a method performed by a wireless device for initiating performance of Quality of Experience, QoE, measurements for a first application. The wireless device receives (402), from a base station, a first request to perform one or more measurements according to a QoE measurement configuration, wherein the request comprises an indication of the QoE measurement configuration, wherein the QoE measurement configuration is associated with a service type of a first application and at least one service subtype of the first application. The wireless device initiates (404) one or more QoE measurements according to the QoE measurement configuration; and transmits (406) a QoE measurement report comprising results of the one or more QoE measurements to the base station.

摘要： An apparatus in a mobile communication network combines information from monitoring IP flows carrying latency sensitive content passing the apparatus and information about the application behavior and target Quality of Experience (QoE) or target connectivity characteristics such as Quality of Service (QoS) from the application to provide ongoing predictions of QoE/QoS. In some cases, the apparatus exploits a probe on a device to generate traffic for learning flow characteristics not obtained from monitoring application IP flows in the network. Embodiments disclosed herein can be used to predict quality metrics for many applications where jitter/latency is a factor affecting perceived quality, such as QoE for a human consumer or QoS for machine type communications. The embodiments are applicable to the analysis of traffic carrying conversational speech.

摘要： Embodiments disclosed herein relate to methods and apparatus for generating video frames when there is a change in the rate of received video data. In one embodiment there is provided a method of processing video data which comprises generating a video frame using received video data, encoding said video frame into a latent vector using an encoder part of a generative model, modifying the latent vector and decoding the modified latent vector using a decoder part of the generative model to generate a new video frame in response to determining a reduction in generating the video frames using the received video data.

摘要： Embodiments include methods for a first radio network node (RNN) in a wireless network to configure quality of experience (QoE) measurements by user equipment (UEs). Such methods include receiving, from a measurement function in the wireless network, a QoE measurement configuration (QMC associated with one or more service types; and configuring one or more UEs with the QMC. Such methods also include sending to a second RNN in the wireless network, a first request for handover of a particular one of the UEs from a first cell served by the first RNN via a first radio access technology (RAT) to a second cell served by the second RNN via a second RAT. The first request includes the QMC. Other embodiments include complementary methods performed by a second RNN or by a UE, as well as first RNNs, second RNNs, and UEs configured to perform such methods.

摘要： Mechanisms for predicting a multimedia session MOS are provided. The multimedia session has a video session and an audio session. The video quality and the audio quality are represented by vectors of per-time-unit scores of video quality and audio quality, respectively. The multimedia session is represented by a vector of the rebuffering start times of each rebuffering event, and a vector of the rebuffering durations of each rebuffering event. Audiovisual quality features are generated from the vectors of per-time-unit scores of video and audio quality. Buffering features are generated from the vector of rebuffering start times of each rebuffering event and the vector of rebuffering durations of each rebuffering event. A multimedia session MOS is then estimated based on the generated audiovisual quality features and the generated buffering features.

摘要： There are provided mechanisms for predicting a multimedia session MOS. The multimedia session comprises a video session and an audio session, wherein video quality is represented by a vector of per-time-unit scores of video quality and wherein audio quality is represented by is a vector of per-time-unit scores of audio quality. The multimedia session is represented by a vector of rebuffering start times of each rebuffering event, a vector of rebuffering durations of each rebuffering event, and an initial buffering duration being the time between an initiation of the multimedia session and a start time of the multimedia session. The method comprises generating audiovisual quality features from the vector of per-time-unit scores of video quality and the vector of per-time-unit scores of audio quality. The audiovisual quality features comprise: a vector of per-time-unit scores of audiovisual quality, calculated as a polynomial function of the vector of per-time-unit scores of video quality and the vector of per-time-unit scores of audio quality; a weighted combination of the per-time-unit scores of audiovisual quality, wherein the weights are exponential functions of a time since the start time of multimedia session and a multimedia session duration; a negative bias representing how a sudden drop in per-time-unit scores of audiovisual quality affects the multimedia session MOS; and a term representing a degradation due to oscillations in the per-time-unit-scores of audiovisual quality. The method comprises generating buffering features from the vector of rebuffering start times of each rebuffering event, calculated from the start time of multimedia session, and the vector of rebuffering durations of each rebuffering event. The method comprises estimating a multimedia session MOS from the generated audiovisual quality features and the generated buffering features.
