  • Patent number: 11877162
    Abstract: A method and system is described that performs dynamic slice management for unmanned aerial vehicles (UAVs). Flight path information associated with a flight path of a UAV is used to determine a predicted optimal application and a predicted optimal network slice for use by the UAV at a location along the flight path. Information associated with the predicted optimal application and the predicted optimal network slice is transmitted to the UAV for use by the UAV at the location. The available network slices to the UAV may be updated based on the determined predicted optimal slice. The UAV may adjust its usage of applications and/or slices based on the information it receives associated with the predicted optimal application and the predicted optimal network slice.

    Abstract: Aspects of the present disclosure include implementing fabric availability and synchronization (FAS) agents within a fabric network. In one example, a first FAS agent executing on a first network device may receive, from a second network device, a command to modify a configuration of a second network device. The first FAS may upgrade the configuration of the first network device based on the command from a current configuration to a new configuration. The first FAS agent increment a state identifier associated with the configuration of the first network device to a new state identifier associated with the new configuration. The first FAS agent may then transmit a control packet that includes the new state identifier. A second FAS agent executing on the second network device may receive the control packet and execute the command to update the configuration of the second network device to the new configuration.

  • Patent number: 11864260
    Abstract: A telecommunication network associated with a wireless telecommunication provider can be configured to switch between New Radio (NR) Dual Connectivity (DC) and NR Carrier Aggregation (CA) in 5G cellular networks. According to examples, a UE is not limited to using a single mode (e.g., either NR CA or NR DC) that is initially selected for use by the UE. For example, a UE can be reconfigured during a session to switch from NR DC to NR CA when the UE moves toward mid-cell and/or a cell edge. In other examples, the UE can be reconfigured to switch from NR CA to NR DC when the UE moves closer to the cell. To determine when to switch, one or more network conditions (e.g., UE RF conditions) can be monitored. In some examples, a gNB can monitor power headroom reports (PHRs) received from the UE to determine when to switch.

A link state message is flooded to each of the nodes in a remaining part of the flooding topology and to the alternative connections, such that the link state message identifies the failure in the network. The failure in the network is resolved by connecting the split flooding topology using the remaining part of the flooding topology and the alternative connections as identified in the link state message.

    Abstract: A layered convergence topology structure for a plurality of sensors is established based on a sensing range and a position relationship of at least one sensor from the sensors. A plurality of pieces of first sensed information, respectively captured through each sensor of the sensors, are divided into at least two first groups based on the layered convergence topology structure. Each piece of first sensed information in respective first group of the at least two first groups is converged to obtain at least two pieces of first converged information. The at least two pieces of first converged information are determined as at least two pieces of second sensed information for convergence to obtain second converged information. When a piece number of the second converged information is one, the second converged information is determined as target converged information.

  • Patent number: 11836663
    Abstract: Techniques are described for cognitive defined network management (CDNM) that seek to perform real-time collection and analysis of raw network data from across a disaggregated wireless network and to dynamically orchestrate network management functions substantially in real time, accordingly. For example, a multi-modal artificial intelligence (AI) engine is trained to normalize the heterogeneous raw network data into homogeneous so-called “golden record data.” A repository of historical golden records can be maintained for generating data models for use in training AI network management applications. An orchestrator can operate to directing execution of pre-developed network management workflows based on results obtained from querying the trained AI network management applications with newly received (real-time) golden records.

  • Patent number: 11838361
    Abstract: Systems, methods, and computer-readable media for reducing distributed storage operation latency using segment routing. In some examples, a method can involve receiving, from a client, a message identifying an intent to store or retrieve data on a distributed storage environment, and sending to the client a segment routing (SR) list identifying storage node candidates for storing or retrieving the data. The method can involve steering a data request from the client through a path defined by the SR list based on a segment routing header (SRH) associated with the request, the SRH being configured to steer the request through the path until a storage node from the storage node candidates accepts the request. The method can further involve sending, to the client device, a response indicating that the storage node has accepted the request and storing or retrieving the data at the storage node that accepted the request.

  • Patent number: 11838201
    Abstract: A method includes generating a first shortest path tree for traffic routing in a network, the first shortest path tree identifying a corresponding shortest path from the network node to other nodes in the network and generating a second shortest path tree for traffic routing after removing an element from the network. The second shortest path tree identifies a corresponding shortest path from the network node to the other nodes in the network with the element removed. A third shortest path tree is generated, which is a weighted version of the second shortest path tree with a weight value added to any node or link in the network sharing a SRLG value with the element removed from the network. Network traffic is enforced based on a comparison of the third shortest path tree with at least one of the first shortest path tree and the second shortest path tree.

  • Patent number: 11838789
    Abstract: Software-defined networking and network function virtualization constructs are leveraged across diverse portions of 5G network infrastructure including radio access network, mobile core, and wide area network to enable a security property to be implemented for a network slice from end-to-end to provide for strong logical and/or physical isolation of slice traffic from other network traffic. One or more network slice controllers are implemented in the 5G network that are interoperable as separate elements, or under centralized control, to enable the underlying diverse network infrastructure to be abstracted and virtualized so that infrastructure properties can be mapped across infrastructure types for the end-to-end slice.

  • Patent number: 11830366
    Abstract: The present invention extends to methods, systems, and computer program products for using geofences to restrict vehicle operation. Aspects of the invention include creating dynamic geofences and limiting vehicle movements (e.g., speed, acceleration, steering, etc.) within and in the vicinity of the dynamic geofences to protect pedestrians from physical harm. In general, radio devices track people in an area by counting the number of devices and calculating the number of people based on average number of devices per person. Using count and location data, a geofence is created when population or population density within an area exceeds a threshold. The geofence can be sent to vehicles to restrict vehicle operation, for example, slowing down or stopping the vehicle, within and around the geofence.
