  • Publication number: 20210377804
    Abstract: The described technology is generally directed towards network traffic splitting for dual connectivity user equipment. A network controller can monitor communications transmitted between radio access network node devices. The radio access network node devices can be associated with different generation communication protocols. The inter-node communications can be used assess relative performance of the radio access network node devices. For example, buffer growth rates can be estimated for the radio access network node devices, and buffer growth rates can be correlated with network node device performance. The relative performance of the radio access network node devices can then be used to adjust network traffic splits between the radio access network node devices.

  • Patent number: 11184517
    Abstract: A system of cameras can be used to generate a complete field of view within an edge network. For example, one camera can have a field of view where part of the view is obstructed by an object and/or by the camera's orientation. Yet another camera that is a part of the edge network can supplement the view of the first camera by providing an alternate view. The two views can be stitched together by a coordinate system such that a complete field of view can be utilized by both cameras. Additionally, where a field of view is not available by any stationary camera, the system can dispatch a mobile camera to help supplement the views.

  • Publication number: 20210336923
    Abstract: An integrated GW (I-GW) can be utilized to facilitate communications with Internet of things (IoT) devices that operate without Internet protocol (IP) addresses, based on assigned preferences and/or priority. In one aspect, the I-GW can efficiently deliver existing services for various types of IoT devices (e.g., that support different non-IP protocols) and can create emerging applications across different vertical applications. Further, the I-GW can leverage mobility network elements to authenticate, prioritize connections, and/or enable data orchestration via underlying software defined network (SDN)-enabled capabilities and/or infrastructure services. By utilizing IoT devices that do not have IP stacks, a cost and/or size of the IoT devices can be decreased and battery life can be significantly extended.

  • Publication number: 20210274412
    Abstract: In 6G, there are multiple radios that can cover the same location at any time, and yet radio failure can occur. However, a mobile edge computing (MEC) platform can increase the footprint of adjacent radios to compensate for a failed radio. To reduce the failure interruption and maintain a quality of experience for a subscriber, the MEC can utilize a virtual session capability to communicate radio change of service characteristics to a service provider. Consequently, the change in service characteristics can comprise an expanded coverage area for adjacent radios such that a mobile device of the subscriber can take advantage of the expanded coverage area without experiencing an interruption in service.
