METHOD FOR END-TO-END TRANSPARENT TRANSPORT OF DATA PACKETS WITHIN A SPACE TELECOMMUNICATIONS SYSTEM USING A NETWORK OF REGENERATIVE SATELLITES WITH ISLS
An on-board method for the end-to-end transparent transport of data packets is implemented by a telecommunications system comprising a first, sending station, a second, receiving station, a first, sending satellite, connected directly to the first station, and a second, receiving satellite, connected directly to the second station, the first satellite and second satellite being interconnected via a spaceborne network. The transport method comprises steps allowing an end-to-end transparent adaptive control loop for the adaptive control of the modulation and of the coding of the access links between the first station and the first satellite and between the second station and the second satellite to be implemented.
SIMULTANEOUSLY BROADCASTING ACKNOWLEDGEMENTS OF RECEPTION OF UPLINK WIRELESS COMMUNICATION
Apparatuses, methods, and systems for communicating through a wireless link are disclosed. A method includes scheduling, by a server, communication between a base station and a plurality of hubs, receiving, by the base station, the scheduled communication, providing, to each hub, a data profile that includes a periodicity, an offset, and a carrier frequency based on the scheduled communication, receiving, by the base station, uplink wireless communication from each of the plurality of hubs according to the data profile of each of the hubs and according to the scheduled communication, and simultaneously broadcasting, by the base station, acknowledgements of reception of uplink wireless communication from each of the plurality of hubs.
Systems and methods for communicating data over satellites
Systems for communicating data through a satellite are disclosed. The systems generally include a radio designed for terrestrial communications that is configured to uplink data to one or more satellites. The one or more satellites are configured to receive the data from the terrestrial radio. In addition, the systems include terrestrial receivers, such as one or more chirp spread spectrum radios, positioned at ground level, which are configured to receive the data from the one or more satellites.
METHODS AND APPARATUS TO PROVIDE AN UPDATE VIA A SATELLITE CONNECTION
Methods, apparatus, systems and articles of manufacture to provide an update via a satellite connection are disclosed. An example method includes scanning a local area network to identify a device in communication with the local area network. A hardware address of the device is determined. The hardware address of the device is compared against a whitelist of hardware addresses included in an update schedule. In response to detecting that the hardware address of the device is included in the whitelist of hardware addresses, an update identified in the update schedule is received via a broadcast distribution system, is recorded, and is transmitted to the device.
FLIGHT DATA ASSISTED ACTIVE ANTENNA SYSTEM FOR AIR-TO-GROUND APPLICATIONS
Methods and apparatuses for controlling radio resources of radio units in air-to-ground mobile communications systems that include at least an aircraft carrying a transceiver station and a ground basestation, apt to communicate with each other. The radio units are provided with beamforming and/or massive MEM antenna systems, and are controlled by the apparatuses using control data. The apparatuses are configured to receive flight data related to the aircraft, estimate a timed trajectory and a required data rate, as a function of the flight data. Then the apparatuses determine a sequence of control data for said antenna systems to form radio beams and/or connectivity spots directed towards said transceiver station, respectively to the ground basestation, while the allocated data rate is at least equal to the required data rate. The sequence of control data is then provided to respective antenna systems.
Selecting a Non-Access Stratum Period Based on a Non-Terrestrial Access Network Type
A wireless device receives access network information indicating an access network type. Based on the access network type, a non-access stratum (NAS) period is selected among: a first value associated with a geostationary earth orbit (GEO) non-terrestrial network (NTN) access network type; and a second value associated with a low earth orbit (LEO) NTN access network type. A NAS procedure is initiated by sending a NAS request message. A start of the NAS period is based on the sending. The NAS procedure is aborted based on an expiry of the NAS period.
COMMUNICATION METHOD, COMMUNICATIONS APPARATUS, DEVICE, AND COMMUNICATIONS SYSTEM
A communication method, a communications apparatus, a device, and a communications system. The method includes: a terminal device receives, by using a first beam, broadcast signals broadcast by N network devices, where each broadcast signal includes a current broadcast moment and identification information of a network device that broadcasts the broadcast signal, and N is a positive integer; the terminal device obtains a second beam corresponding to the broadcast signals, where a width of the first beam is greater than that of the second beam; the terminal device measures the broadcast signals of the N network devices by using the second beam corresponding to the broadcast signal; the terminal device obtains, based on a measurement result, a second beam corresponding to a target network device, where the target network device is one of the N network devices.
SATELLITE INTEGRATED RECEIVER DECODER AND CONFLICT DETECTING METHOD
A satellite IRD (Integrated Receiver Decoder) complies with DiSEqC protocol and is capable of receiving a program of a specific channel from a single cable interface device through a cable. The DiSEqC transmitter transmits a first command corresponding to the specific channel to the single cable interface device through the I/O interface and the cable. The DiSEqC receiver acquires a second command transmitted on the cable through the I/O interface in response to the DiSEqC transmitter transmitting the first command. The detecting circuit compares the second command with the first command to generate a comparison result. The DiSEqC receiver monitors the I/O interface in response to the comparison result indicating that the first command and the second command are different to determine whether there is a command other than the first command transmitted on the cable.
SYSTEM AND METHOD FOR SEAMLESS BROADCAST DATA RECOVERY USING NON-INTRUSIVE TERRESTRIAL AND BROAD BAND CONNECTIVITY
A system for data recovery using non-intrusive terrestrial and broad band connectivity of transmission of a data stream, the system having an IP distribution network for transferring the data stream from a sender to a plurality of receivers, the system having: a transmission center receiving the data stream from the sender and sending a continuous IP data stream to the IP distribution network and sending a broadcast data stream to a broadcast network; at least one registered/assigned recovery server connected to the IP distribution network and assigned to at least one of the plurality of receivers, the at least one recovery server receiving a protected IP stream from the transmission center; at least one of the plurality of receivers sending a recovery request to at least one recovery server when the respective receiver detects an erroneous/missing packet; and wherein the protected IP stream is encapsulated into RTP in the transmission center and the at least one recovery server sends a recovery data stream to the at least one of the plurality of receivers following receipt of the recovery request.
