    摘要: An enclosure state, e.g., enclosed or not enclosed, of a communications device is determined based upon one or more of: i) a selected set of environmental sensor measurements, performed by the communications device, ii) a corresponding set of expected outdoor environmental conditions, e.g., sourced from a weather server, iii) weighting factors corresponding to each of the environmental conditions, and/or iv) a threshold value. The communications device performs one or more actions based on the determined enclosure state, enclosed, e.g. indoors, or not enclosed, e.g. outdoors. Exemplary actions include controlling a transmitter or receiver setting, communicating the enclosure state determination to an emergency responder or controlling an application resident on the communications device based on the determined enclosure state. Various exemplary actions contribute to efficient use of communications device resources, e.g., battery power and air link resources and/or contribute to increasing efficiency and/or safety with regard to emergency responses.

    摘要: The system trains a machine learning model using a loss function, with a part that penalizes overall signal loss, and a second part of the loss function that penalizes texture loss. The system computes a first neural feature of a first media frame stored by a media server using the trained machine learning model. The system causes a client device to receive a second media frame as a part of a media stream from the media server where the second frame is a modified version of the first media frame. The system causes the client to compute a second neural feature of the second media frame using the trained machine learning model, and compute a QoE metric based on the first neural feature and the second neural feature. The system receives the QoE metric, and uses it to modify at least one parameter of the media stream.
