Abstract: Facilitating geo-distributed dynamic network system for ubiquitous access to multiple private networks in advanced networks (e.g., 4G, 5G, and beyond) is provided herein. Operations of a method can comprise establishing, by a system comprising a processor, a first communication link between a first network device and group of devices connected via a private network connection. The method also can comprise establishing, by the system, a second communication link between the first network device and a second network device. The second network device can be included in a group of network devices associated with a communication network provider. Further, the second network device can facilitate communication with a communication device.

Abstract: A system can obtain a labelled data set, including historic video data and labelled events. The system can divide the labelled data set into historic training/testing data sets. The system can determine, using the historic training data set, a plurality of different parameter configurations to be used by a video encoder to encode a video that includes a plurality of video frames. Each parameter configuration can include a group of pictures (“GOP”) size and a scenecut threshold. The system can calculate an accuracy of event detection (“ACC”) and a filtering rate (“FR”) for each parameter configuration. The system can calculate, for each parameter configuration of the plurality of different parameter configurations, a harmonic mean between the ACC and the FR. The system can then select a best parameter configuration of the plurality of different parameter configurations based upon the parameter configuration that has the highest harmonic mean.

Abstract: Devices, computer-readable media, and methods for submitting a modified voice input to a service based upon a user intent determined from a voice input in accordance with a voice interface of the service are disclosed. A processing system including at least one processor may obtain a voice input of a user, determine an intent from the voice input, identify a first service, from among a plurality of services, in accordance with the intent, and formulate a first modified voice input from the voice input in accordance with a voice interface of the first service, where each of the services is associated with one of a plurality of different voice interfaces. The processing system may further submit the first modified voice input to the first service, obtain a first voice response from the first service, and present a voice output to the user in accordance with the first voice response.

Abstract: Aspects of the subject disclosure may include, for example, embodiments for determining a first motion-to-update latency of a mobile device in relation to receiving a video content update provided by a video content server. Further embodiments include, responsive to determining that the first motion-to-update latency exceeds a threshold: determining a motion-to-update latency of the mobile device in relation to receiving video content updates from a plurality of edge servers resulting in a plurality of motion-to-update latencies, identifying a second motion-to-update latency from the plurality of motion-to-update latencies that is below the threshold, identifying an edge server associated with the second motion-to-update latency, and transmitting video content to the edge server to mitigate the first motion-to-update latency. The edge server provides a portion of the video content at different time intervals to the mobile device and the video content comprises panoramic video content. Other embodiments are disclosed.

Abstract: A processing system including at least one processor may receive a request from a client device for a deployment of a client service to a mobile edge infrastructure of a telecommunication network, the mobile edge infrastructure including host devices, and determine at least one requirement for the client service, including at least one of: a distance requirement, comprising a maximum distance between the client device and a candidate host device for deploying the service, or a latency requirement, comprising a maximum latency between the client device and the candidate host device for deploying the service. The processing system may further determine at least one available host device of the mobile edge infrastructure that meets the requirements, select a host device from among the at least one available host device to run the client service, and instruct the client device to connect to the host device that is selected.
