  • Publication number: 20210165406
    Abstract: Deployed drones are managed. For instance, a first drone detects whether the first drone is in communication with a command center via a first communication network to determine a configuration parameter of a first message to broadcast discovery information associated with the first drone. In response to the first drone being in communication with the command center via the first communication network, the first drone broadcasts the first message configured with a first value for the configuration parameter. Or, in response to the first drone not being in communication with the command center via the first communication network, the first drone broadcasts the first message configured with a second value for the configuration parameter different from the first value.

  • Patent number: 11019157
    Abstract: Techniques for instantiating and managing microservices for use in connection with devices associated with a core network are presented. A service management component (SMC) can determine a subgroup of services to be used for a group of one or more devices based on results of analysis of characteristics and service conditions associated with the group of devices, wherein a characteristic can relate to whether a device is stationary or mobile. At a desired time(s), which can be periodically, dynamically, or upon request, SMC can instantiate or facilitate instantiating the subgroup of services to facilitate communicating data associated with the device(s) using the subgroup of services. The services can comprise a connectionless service, connection-oriented service, charging service, authentication service, UPF services, or other services. SMC can employ the connectionless service when a device is stationary, but the connectionless service can be extended to devices when they are nomadic or mobile.

  • Publication number: 20210153115
    Abstract: Resource-sensitive token-based access point selection is disclosed. A user equipment (UE) can generate a request for resources that can be shared with an selection component remote from the UE. The request for resources can be generated independent of the UE receiving information about an access point (AP) in range of the UE. The selection component can pair the UE with an AP resource based on AP data and UE data. The selection component can generate a token comprising information related to the pairing. The UE can receive the token via a device other than the AP or via the AP. The token can be employed by the UE to initiate a link to the AP to enable use of the AP resource by the UE. The link can be resource sensitive in view of the request for resources and available AP resources.

  • Patent number: 11006314
    Abstract: Various embodiments disclosed herein provide for a dynamic access slice pooling system with software defined network (SDN) controlled capabilities in a 5G wireless communications system. A radio access network device can have one or more slices instantiated on the device that facilitate various services being requested by user equipment devices. A slice can have one or more virtual network functions that are specialized for particular services. When a user equipment device requests a service, the service can be assigned to a slice based on the type of service being requested. If the type of slice associated with the service is not currently operational, the SDN controller on the radio access network device can instantiate a new slice with the virtual network functions selected for the service being requested.

  • Patent number: 11005743
    Abstract: Aspects of the subject disclosure may include, for example, a method comprising providing services over a network to a device, and constructing device capability and usage profiles. A level of service quality for the device is adjusted by adjusting a latency criterion regarding connection of the device to the network; adjusting a speed of transmissions to or from the device; and altering a routing of transmissions to or from the device. The network can be partitioned so that the adjusted service quality level is provided by a network portion having a predetermined level of resources. The adjusted service quality level can comprise a first level while the device is active and a second level while the device is inactive; the first level is higher than the second level. The first and second levels are lower than a service quality level provided by another network portion. Other embodiments are disclosed.

  • Patent number: 10977952
    Abstract: Concepts and technologies disclosed herein are directed to intelligent drone traffic management via a radio access network (“RAN”). As disclosed herein, a RAN node, such as an eNodeB, can receive, from a drone, a flight configuration. The flight configuration can include a drone ID and a drone route. The RAN node can determine whether capacity is available in an airspace associated with the RAN node. In response to determining that capacity is available in the airspace associated with the RAN node, the RAN node can add the drone ID to a queue of drones awaiting use of the airspace associated with the RAN node. When the drone ID is next in the queue of drones awaiting use of the airspace associated with the RAN node, the RAN node can instruct the drone to fly through at least a portion of the airspace in accordance with the drone route.

  • Patent number: 10970902
    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: 10973083
    Abstract: Communication between drones of multiple drone meshes is disclosed. Attributes of drones can be cataloged by a network device. A portion of the drone attribute catalog can be received by a drone belonging to a drone mesh. The drone can determine, based on the portion of the drone attribute catalog, an adaptation to the drone mesh in response to a change in a status of a drone of the drone mesh. The adaptation of the drone mesh can comprise adding a drone to the drone mesh, removing drone from the drone mesh, merging the drone mesh with another drone mesh, splitting the drone mesh into a plurality of drone meshes, forming a submesh of the drone mesh, etc. Receiving the portion of the drone attribute catalog can facilitate self-organization and/or self-optimization of a drone mesh by drones comprising the drone mesh. A drone can concurrently be a member of one or more drone meshes as a result of the adaptation of the drone mesh.

  • Patent number: 10966072
    Abstract: In a 6G network, microservices can be utilized in the absence of a core network. For example, after a mobile device has authenticated, through its carrier network, with a transport service layer, microservices can be allocated to the mobile device without having to be transmitted via the core network. Thus, removing the core network from the process can generate a direct line of microservices from the transport layer to the end-user. Furthermore, additional microservices and/or resources can be access through a microservices library. Consequently, packets can be securely transmitted be a wireless network facilitating sending packet profile data from one to many node devices in anticipation of the packet traversing the various node devices.
