    摘要: In some embodiments, a disclosed method involves receiving, by a source gateway, a call request from a source user terminal for establishing a call with a destination user terminal. The method further involves determining, by a source client proxy of the source gateway, a capability related to a parameter(s) of the source user terminal and a capability related to a parameter(s) of the destination user terminal. Also, the method involves sending, by the source client proxy, a call capability offer to a destination gateway based on the determined capabilities. Additionally, the method involves determining, by a destination client proxy of the destination gateway, whether the destination user terminal can support the call capability offer. Also, the method involves sending, by the destination client proxy, a call initiation message to the destination user terminal, when the destination client proxy determines that the destination user terminal can support the call capability offer.

    摘要: An apparatus includes an analog front end to receive an analog input including user data, and an analog-to-digital converter to convert the analog input to digital signals including the user data. A digital channelizer may process the digital signals to generate frequency slices of user data, and a digital combiner may assemble the frequency slices to form output sub-bands of user data. A digital switch may route the frequency slices from the digital channelizer to the digital combiner according to a selected map of a plurality of available maps. The apparatus also includes a map selector to communicate map select data that indicates the selected map. The digital channelizer may receive and insert the map select data into the frequency slices in-band with the user data thereof. And the digital switch may interpret the map select data inserted into and route the frequency slices according to the selected map.

    摘要: An example system for satellite payload communications includes a digital channelizer and a regenerative communications subsystem (RCS). The digital channelizer includes a plurality of inputs for receiving a plurality of signals from a plurality of uplink beams and a plurality of outputs for outputting the plurality of signals. The RCS includes a plurality of inputs selectably coupled to the digital channelizer outputs to receive signals from selected ones of the digital channelizer outputs and a plurality of outputs selectably coupled to the digital channelizer inputs to transmit the processed signals to selected ones of the digital channelizer inputs. The RCS is configured to process selected ones of the plurality of signals to produce processed signals.

    摘要: A system and method for an adaptive network of network access nodes comprises a global network operations center (GNOC) receiving operator inputs and generating a global policy according to the operator inputs. The GNOC and/or a distributed network gateway (GW) generate configuration commands for configurations for at least one of the network access nodes based on the global policy, transmit the configuration commands to at least one of the network access nodes, and receive telemetry from at least one of the network access nodes. The distributed network GW transmits a summary of key performance indicators (KPIs) to the GNOC and the GNOC revises the global policy according to the summary of KPIs.

    摘要: A method includes receiving, at a network service exchange system, a request from a device. The request indicates one or more service parameters. The method includes, in response to receiving the request, validating the device and the one or more service parameters. A reverse auction is performed to select a service provider from among a plurality of candidate service providers. The service provider is selected based on the one or more service parameters. The method further includes, after selecting the service provider, performing an over-the-air provisioning process to enable the device to communicate using a network associated with the service provider.

    摘要: Systems, methods, and apparatus for mobile routing for non-geostationary orbit (NGSO) systems using virtual routing areas (VRAs) are disclosed. A disclosed method comprises generating a plurality of routing graphs for each of a plurality of VRAs. Each of the routing graphs is for a different period of time, and comprises a gateway and satellites that are within view of each other and of the gateway during the period of time associated with the routing graph. The method further comprises generating at least one time-sliced graph for each of the routing graphs, where each of the time-sliced graphs shows connectivity between at least some of the satellites, which are on the routing graph associated with the time-sliced graph, with each other. Further, the method comprises, during each of the periods of the time, establishing communications between the satellites according to each of the time-sliced graphs for the period of time.
