A method is described of minimizing fronthaul data load and beam management realization in a cellular non-terrestrial network using a satellite network system, comprising: providing a plurality of cells of a cellular service based on satellite systems in a satellite constellation to be used in a pre-defined pattern when being translated into beams, wherein a given cell covers more than a single geographic location in a non-adjacent manner; wherein a reuse pattern of cells avoids two cells covering an overlapping area; and the reuse pattern also avoids neighbor cells.

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 enhanced L-band Digital Aeronautical Communications System (LDACS) may include LDACS ground stations, and LDACS airborne stations configured to communicate with the LDACS ground stations. The enhanced LDACS may also include a Cloud-based network controller configured to allocate LDACS resources to the LDACS ground stations and the LDACS airborne stations based upon a number of LDACS airborne stations, respective flight paths of each LDACS airborne station, a respective type of each LDACS airborne station, and historical data on communication use for each LDACS airborne station.

A system and method for communicating with an Internet Of Things (IoT) device via a satellite link. The method includes assigning a transmission mode to a physical channel, where the physical channel supports multiple timeslot durations and the transmission mode is selected from a single user (SU) or a multi-user (MU); selecting a timeslot duration from the multiple durations for a payload; obtaining, when the transmission mode is SU, a timeslot grant for use of the physical channel for the timeslot duration; and transmitting a burst including the payload, where the burst is transmitted synchronized with the timeslot grant when the transmission mode is SU and the burst is transmitted without synchronization when the transmission mode is MU.

Multibeam coverage for a high altitude platform (“HAP”) is disclosed. An example method to provision a HAP includes determining an altitude range at which the HAP will operate and determining a minimum elevation angle from the ground to the HAP. The method also includes determining a coverage area of the HAP based on the altitude range and the minimum elevation angle and partitioning the coverage area into substantially equal-sized cells. The method further includes assigning an antenna to each of the cells and determining a beamwidth and an elevation angle for each antenna to provide communication coverage to the corresponding cell. The method moreover includes determining an aperture for each of the antennas based on the beamwidth and the elevation angle to provide the substantially equal-sized cells.

The present disclosure provides a satellite control method and apparatus, comprising: receiving a to-be-photographed target site input by a user; calculating first moment information corresponding to each satellite entering the target site, according to location information of the target site and operation orbit information of the each satellite in a plurality of satellites; and determining, from the plurality of satellites, at least one to-execute satellite to photograph the target site according to the first moment information corresponding to the each satellite entering the target site.

Dynamic in-route reconfiguration in a satellite network includes receiving at least one of transmit power capability and demand requirements from one or more active satellite terminals of the satellite network, determining a resulting in-route configuration during operation of the satellite network based on the received at least one of transmit power capability and demand requirements, comparing the determined resulting in-route configuration to a current in-route configuration. When the determined resulting in-route configuration is different from the current in-route configuration, establishing the determined resulting in-route configuration as the current in-route configuration and storing the established current in-route configuration in a dynamic in-route reconfiguration manager, and transmitting the established current in-route configuration to the one or more active satellite terminals.

Systems, apparatuses, and method may provide unmanned aerial system communication. A method performed by at least one processor included in an unmanned aerial system (UAS) includes: transmitting, to a UAS Service Supplier (USS) implemented on at least one server, a first registration request to register a first remote identification (RID) corresponding to the UAS with the USS; receiving, from the USS, an indication that the first RID is a duplicate RID that is registered with the USS; determining, based on the first RID, a second RID corresponding to the UAS; and transmitting, to the USS, a second registration request to register the second RID.

A Multi-Access Edge Computing (MEC) system is provided. The MEC system includes a user equipment (UE), an MEC device, and a core network. The MEC device includes a relay User Plane Function (UPF) module, a first UPF module, and a second UPF module. The core network performs a UPF path management corresponding to the UE based on a notification of the MEC device. When the UE attaches to a network, the MEC device establishes an idle session between the UE and the relay UPF module. When the MEC device determines that a service for the UE needs to be switched from the first UPF module to the second UPF module and the second UPF module has not been activated, the MEC device notifies the core network to switch the service for the UE from the first UPF module to the relay UPF module first.

In a method and apparatus for inter-satellite communications, transmissions between a satellite and neighboring satellites that share an orbital plane occur via an aft antenna or a forward antenna and transmissions between the satellite and neighboring satellites that do not share an orbital plane occur via the aft antenna or the forward antenna timed during orbital plane crossings. This occurs even if the total path length and number of links is higher than inter-satellite communications that use side-to-side transfers.
