Abstract: A method, a device, and a non-transitory storage medium are described in which a cellular device-satellite communications service is provided. The service may provide establishment, maintenance, and termination of uplink and downlink connections via a satellite network, a terrestrial network, and both based on network information and satellite information. The service may also provide scheduling for user plane traffic via the uplink and downlink connections.

Abstract: A device may receive capacity information associated with a plurality of base stations, and may receive user equipment demands associated with the plurality of base stations. The device may receive, from a satellite, a satellite backhaul demand associated with the satellite, and may calculate excess backhaul capacities associated with the plurality of base stations, based on the user equipment demands and the capacity information. The device may identify a base station, of the plurality of base stations, to provide a satellite backhaul path for the satellite, based on the excess backhaul capacities and the satellite backhaul demand, and may provide, to the base station, a message instructing the base station to activate a satellite antenna associated with the base station. The device may provide, to the satellite, data identifying the base station, and may establish the satellite backhaul path for the satellite, via the base station.

Abstract: A method and apparatus for ultrasonically welding the overlapped portions of a continuous metal strip that has been rolled about a longitudinal axis to form a tubular product. The metal strip is rolled around the outer surface of an internal mandrel by means of one or more forming tools disposed around the mandrel. At the exit end of the forming tool, a stationary, rigid, non-resonant anvil is formed by a portion of the outer surface of the mandrel so that the anvil is located inside the rolled metal strip and supported by that portion of the mandrel which extends outwardly between the longitudinal edges of the strip upstream of the point where the strip edges are brought together. As the rolled metal strip is advanced, the longitudinal edges thereof are overlapped and passed over the anvil.
