Patent number: 11329875Abstract: A method of switching from a first gateway within a plurality of first gateways to a second gateway in a network includes precaching configuration information on the second gateway, that is within the first gateways, prior to switch-over to the second gateway. The first gateway from which the second gateway is being switched is identified. The second gateway is configured in accordance with the configuration of the first gateway based on the precached configuration information prior to the switch-over to the second gateway. Data traffic from data applications using the network is replicated and sent to the first gateway and the second gateway. Bandwidths allocated to terminals in the network are frozen in association with the switch-over to the second gateway. The bandwidths allocated to the terminals in the network are unfrozen based at least in part on an indication of completion of the switch-over to the second gateway.Type: GrantFiled: February 12, 2021Date of Patent: May 10, 2022Assignee: HUGHES NETWORK SYSTEMS, LLCInventors: David Whitefield, Robert James Torres, John Leonard Border, David Alan Roos, Stanley Edward Kay

Patent number: 11283512Abstract: A method and system for installing a terrestrial antenna for a satellite communication network. In the system and method, a remote unit is provided to an installation location for the terrestrial antenna. The remote unit is configured to communicate with a satellite of the satellite communication network and includes a memory in which is stored antenna information pertaining to positioning of the terrestrial antenna with respect to a virtual beam generated by the satellite. The information is accessible by a code. Thus, the antenna information is access from the memory at the installation location using the code, and the terrestrial antenna in relation to a virtual beam generated by the satellite based on the antenna information accessed from the memory at the installation location.Type: GrantFiled: September 20, 2019Date of Patent: March 22, 2022Assignee: HUGHES NETWORK SYSTEMS, LLCInventors: Yeqing Tang, David Whitefield, Aniket Pugaonkar, Adam Axelrod, Archana Gharpuray

Patent number: 11044007Abstract: A system and method for providing backup recovery from outage at a primary gateway in a satellite communication system. Upon detecting an alert indicative of an outage, communication between the primary gateway and a plurality of terminals located within spot beams serviced by the primary gateway is suspended. A pre-switchover routine is performed to initialize a backup gateway capable of being substituted for the primary gateway, and a switchover routine is performed to transfer operations from the primary gateway to the backup gateway. Communication is subsequently enabled between the backup gateway and the plurality of terminals.Type: GrantFiled: August 19, 2019Date of Patent: June 22, 2021Assignee: HUGHES NETWORK SYSTEMS, LLCInventors: David Whitefield, Michael J.
