  • Patent number: 11343729
    Abstract: A method and system for controlling air-interface connectivity of a user equipment device (UE). A computing system detects, when the UE has dual connectivity including a first air-interface connection with a first access node and a second air-interface connection with a second access node, and when the first air-interface connection is defined on a first carrier, that the UE is moving toward a geographic area where UEs that were served by the first access node on the first carrier as part of dual connectivity lost their dual connectivity due to their having insufficient aggregate dual-connectivity throughput. And based at least on the detecting, the computing system reconfigures the first air-interface connection of the UE's dual connectivity to be defined on a lower-frequency second carrier, to help avoid having the UE lose its dual connectivity.

  • Patent number: 11343195
    Abstract: Systems and methods are described for streaming data between a user device and a remote computing environment via a “switchboard” service that enables interaction without the user device or the remote computing environment establishing additional connections. A first routing device receives a connection from a user device that requests routing a data stream to or from a remote computing environment. The first routing device processes the request by generating a token, which is passed to the remote computing environment along with the request. The remote computing environment passes the token to a second routing device, which decodes the routing token to identify the first routing device. The second routing device then passes the request token to the first routing device, which responds by establishing a route for streaming data between the connection made with the user device and the remote computing environment via the routing devices.
