A system for inroute throttling in a satellite network is disclosed. The system includes an IP Gateway (IPGW) that may compute a volume usage count of inroute traffic associated with a terminal, compare the computed volume usage count of inroute traffic with a first threshold, and transmit, based on the comparison, a Fair Access Policy (FAP) state to the terminal. The FAP state corresponds to one of a throttled and an unthrottled. The system further includes an Inroute Group Manager (IGM) that may receive, from the terminal, the FAP state and apply a FAP, on the inroute traffic from the terminal, corresponding to the received FAP state.

Systems and methods for introute throttling in satellite networks

Systems and methods for outroute load balancing in a multi-band hybrid satellite communication system include comparing the load metric of each of code rate organizers (CROs) to a threshold value; placing each CRO in one of a surplus load balancing set and a deficit balancing set based on a value of the load metric; and determining a probability metric for each satellite terminal associated with each of the CROs in the surplus load balancing set. The probability metric indicates a probability of the terminal moving to one of the CROs in the deficit load balancing set. At least one satellite terminal associated with one of the CROs in the surplus load balancing set is then caused to switch to one of the CROs in the deficit load balancing set based on the probability metric of the at least one satellite terminal.

Multi-band hybrid satellite communication systems and methods

Systems and methods for a satellite communication system include identifying highly active terminals (HUTs) in a spot beam of a satellite; determining a first ratio of single-band HUTs that operate in a first frequency band only to multi-band HUTs that operate in the first frequency band and a second frequency band; and determining a second ratio of outroutes for the first frequency band to outroutes for the second frequency band. When the first ratio is less than the second ratio, a first step of balancing the single-band HUTs across the outroutes for the first frequency band is performed, and then the multi-band HUTs are balanced across both the outroutes for the first frequency band and the outroutes for the second frequency band. When the first ratio is greater than the second ratio, the single-band HUTs and the multi-band HUTs are allocated based on at least one weight factor.

An apparatus method and system are disclosed for dynamically implementing spectrum configuration plans in a satellite communication system. A spectrum configuration plan is created, and validated to determine if it can be utilized within the predetermined coverage area. If any errors are generated while validating the spectrum configuration plan, it is rejected. Otherwise, system components are configured to provide communication within the predetermined coverage area using parameters specified in the spectrum configuration plan. The spectrum configuration plan is also transmitted to all terminals in the coverage area. The spectrum configuration plan is subsequently implemented for all communication within the predetermined coverage area.

A system and method for integrating 5g and satellite services. A data stream is received from a first network, and traffic conditions in the first network and a plurality of second networks are analyzed. The data stream is segmented into a first portion and at least one second portion based on the analysis of the traffic conditions, and transmitted over the plurality of second networks. The first portion of the data stream and the second portions of the data stream are received at a destination. The first portion of the data stream and the second portions of the data stream are subsequently reassembled, using reassembly information, to reproduce the data stream received from the first network.

Some implementations of the disclosure relate to dynamic switching of a satellite inroute data path between a Time Division Multiple Access (TDMA) method and a Time Division Multiplexing (TDM) method. In one implementation, a satellite terminal comprises one or more processors; and one or more non-transitory computer-readable storage media configured with instructions executable by the one or more processors to cause the satellite terminal to perform operations comprising: communicating, using the satellite terminal, over an inroute TDM channel; determining, based on an ingress traffic rate to the satellite terminal or a determination that the satellite terminal has not received any traffic flows classified for communication using TDM, to switch communications from the inroute TDM channel to an inroute TDMA channel; and after determining to switch communications, switching, at the satellite terminal, from communicating over the inroute TDM channel to communicating over the inroute TDMA channel.

An apparatus, system, and method for balancing traffic loads on beam outroutes that contain both multicast and unicast traffic. An outroute is designated for supplying at least multicast traffic within a beam of a satellite communication system. Terminals interested in receiving the multicast traffic are moved to the designated outroute. Traffic loads on all outroutes within the beam, including the designated outroute, are compared to determine if variations in the traffic loads exceed a predetermined threshold. A load balancing routine is performed to redistribute the traffic loads on all outroutes, while excluding any terminal that is actively receiving the multicast traffic from the load balancing routine.

Systems and methods are provided to achieve dynamic bandwidth allocation among terminal groups (TGs) with proportional fairness in terms of both throughput and spectrum usage across a network. Quality of service (QoS) metrics for such TGs can be satisfied in terms of maximum throughput and spectrum utilization, while also satisfying QoS metrics such as latency, throughput, and prioritized traffic services for individual terminals within the TGs. A centralized bandwidth manager can be utilized to manage such dynamic bandwidth allocation across multiple Code Rate Organizers (CROs), including environments in which the multiple CROs manage communications across multiple IPGWs for multiple terminal groups. Because, in such environments, a given conventional CRO cannot effectively manage allocations across the entire network, the centralized bandwidth management functionality can be introduced to assess the flows for multiple TGs across multiple CROs and to make bandwidth allocations accordingly.

A satellite communication system and method for resizing an outroute carrier from a gateway to a terminal population including determining, at the gateway, an insufficiency based on an Uplink Power Control (ULPC) function in conjunction with an Adaptive Coding and Modulation (ACM) function failing to maintain the outroute carrier in operation; and downsizing, at the gateway based on the insufficiency, the outroute carrier by decreasing a symbol rate of the outroute carrier from the gateway while maintaining the aggregate carrier output power level to increase an outroute carrier margin, where the insufficiency is based on a fade. The outroute carrier may be upsized when the insufficiency expires or is reduced.

The present teachings include a method and computing apparatus for triggering synchronization of a satellite modem to a carrier frequency of a beam of a satellite, retrieving ephemeris information for the satellite and beam configuration information for the beam, calculating a velocity of the satellite per the ephemeris information, and adjusting the carrier frequency of the satellite modem when communicating via the beam to compensate for a doppler offset induced in the carrier frequency by the velocity. In the method, the satellite has a satellite type selected from a Geosynchronous Earth Orbit (GEO), Medium Earth Orbit (MEO) or Low Earth Orbit (LEO) type of satellite, and the satellite type is different than a satellite type of an immediately preceding synchronization.

A method for balancing inroute traffic load that contains both guaranteed QoS and best effort traffic. Hierarchical grouping levels are defined with the lowest level corresponding to inroutes within the system. Certain levels have common symbol rates, modulation rates, or both. When a new terminal requires admission, it is assigned to entries in the different hierarchical levels so that the inroute traffic load across all levels are balanced. Terminals are admitted to inroutes based, in part, on their channel quality indicator. Inroute traffic load can periodically rebalance based on elapsed time or terminal redistribution.
