  • Publication number: 20220159749
    Abstract: A mobile edge computing (MEC) architecture can facilitate utilization of virtual multi-point non-internet protocol (IP) connections in radio access networks (RAN). Thus, the same mobile device can be addressed with multiple radio access technologies (RATs). The MEC can provide service continuity in multi-access technologies using virtual session, and the MEC can terminate a main session between a core network and the MEC, for the mobile device, via a single IP address, Based on the services and the states of the access network in the multi-access environment, the MEC can dynamically select the RAT and access point as the target to deliver the service over the RAN.

  • Publication number: 20220159522
    Abstract: Automatic neighbor relationships (ANR) and voice over new radio (VoNR) microservices can be implemented within a radio access network intelligent controller (RIC), which receives load information from network nodes and user equipment measurements from user equipment. The RIC can create and maintain real-time load information and leverage slicing knowledge of neighbor cells during mobility to direct the user equipment to various network slices. Thus, an enhanced radio access network (RAN) neighbor relationship that utilizes slicing information and VoNR preferences based on current and historical data can provide slice level RAN neighbor visibility on top of physical ANR relationships to enable enhancements for mobility management optimization for VoNR functionality.

  • Patent number: 11336366
    Abstract: In response to a determination that network communication traffic at a network node relates to an emergency communication, a network controller can be operable to analyze a network condition associated with the network node. Based on an analysis of the network condition, the network controller can facilitate an adjustment to a partition of an integrated access and backhaul link. The network controller can further be operative to determine whether an operator policy is applicable to the adjustment of the partition. Additionally, the network controller can be operable to facilitate the selection of a path to route the emergency communication based upon the network condition and the operator policy.

  • Patent number: 11337132
    Abstract: A more efficient network can be achieved using a network-based controller to configure routing tables to route data traffic to and from transmission points. Dynamic partitioning of network resources between the transmission points and a backhaul can be performed in conjunction with a resource scheduler of a network-based controller. The scheduler can relay scheduling metrics or benefit metrics from the network-based controller to the transmission points. Backhaul route optimization can also be used to select relay transmission points based upon conditions being determined to be satisfied.

  • Patent number: 11310642
    Abstract: Peripheral devices such as wearables can link to mobile devices to access network elements. These peripheral devices can comprise a communication part and a processing part. Each of these parts, specially the processing part of the next item in a communication chain, can be multiple times larger and stronger than the previous linked item. For instance, the peripheral device can be connected to the mobile device which can be in line connected to an NodeB device. Because the processing power of mobile device can be several times stronger than the peripheral, a mobile edge computing platform and a multi-access application function facilitate sharing of processing power capabilities between the peripheral devices, mobile devices, and/or the NodeB devices.

  • Patent number: 11297555
    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.

    Abstract: Global position system tagging the movement of an object and extrapolating its direction and speed can be used for various services including emergency-based services. Location data can be computed using edge computing nodes. The extrapolation system can account for feedback from responding user devices and utilize the user device's location at the time of reporting to facilitate determining the direction, location, and/or speed of a moving object. This data can then be utilized to generate augmented reality displays for mobile devices and/or vehicles that utilize the system. The ability to calculate directional information with edge computing nodes can comprise an ability to add enriched data by predicting an object's whereabouts, route, and/or final destination.

  • Patent number: 11284455
    Abstract: A method and apparatus for session management in a wireless network are disclosed. For example, a user endpoint (UE) device, sends a request for a session internet protocol (IP) address assignment using an interface IP address, configures the UE device with the session IP address, provides to a controller an association of the interface and session IP addresses, and receives packets addressed to the session IP address via an access network entity associated with the interface IP address. In one example, a controller receives an association of an interface IP address with a session IP address from an attached UE device, provides to a network node an update on a route to reach the session IP address through the interface IP address, identifies an active interface IP address to receive packets, and configures an open flow switch or router for routing the packets towards the active interface IP address.

  • Patent number: 11275628
    Abstract: A method for outputting notification information, a server and a monitoring system are provided. In the method, a database including a correspondence between feature value models and forewarning levels is constructed in advance; a feature value of the audio information is acquired (S102), the acquired feature value is matched with the feature value models in the database (S103), and then a forewarning level corresponding to the audio information is determined (S104); the notification information is output (S107) when the forewarning level meets a preset condition (S105). It can be seen that, the notification information is output by analyzing the audio information, without determining the active targets in the video image; even if there are many active targets in the scene and the trajectories thereof are confusing, the notification information may still be accurately output.

  • Publication number: 20220078333
    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.
