Description

Technical Field

[0001] This application relates to the field of satellite communications, and more specifically, to a satellite communication method and system. Background Technology

[0002] Low Earth Orbit (LEO) satellite communication systems are characterized by low launch costs, simple constellation deployment, low communication attenuation, and short transmission latency. In recent years, LEO satellite communication technology has received considerable attention and has become the mainstream trend in satellite internet technology. LEO satellite communication constellation systems, represented by OneWeb and Starlink, have emerged. OneWeb satellites employ a transparent relay mode, requiring the deployment of ground gateway stations globally to support satellite signal delivery. Starlink, in its second-generation system, adopts a regenerative processing mode throughout, with satellites equipped with inter-satellite links. Data processed by the satellites is routed and transmitted via these inter-satellite links, reducing the need for globally deployed ground gateway stations.

[0003] Furthermore, the international standards organization 3GPP has completed Release 17 (R17) of the non-terrestrial network technology standard, which only supports transparent forwarding mode satellite communication. In Release 19, 3GPP has initiated research on satellite communication standards based on regenerative processing mode. Therefore, both from the perspective of the evolution of standardization research and the current construction of large constellations, transparent forwarding mode LEO satellites and regenerative processing mode LEO satellites will coexist for a considerable period.

[0004] Currently, among low-Earth orbit communication satellites, those with regenerative processing capabilities are more expensive than transparent relay satellites because they require additional satellite receiving and processing equipment and inter-satellite link devices. However, these inter-satellite links allow for the routing and transmission of user data, preventing the satellite from failing to provide access services in areas where ground gateway stations cannot be deployed. Transparent relay satellites offer simple functionality, low cost, and high reliability, but require the deployment of ground gateway stations in the service area to provide access services to users.

[0005] Because regulatory methods differ across countries, the International Telecommunication Union (ITU) allocates frequencies in multiple regions globally. This can lead to signal and service delivery issues for low-Earth orbit (LEO) satellite communication systems in countries outside of the deployment sites. There is a possibility that services may not be permitted in certain regions, resulting in a waste of constellation service capabilities.

[0006] There is currently no effective solution to the above problems. Summary of the Invention

[0034] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0035] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.

[0036] To better understand the embodiments of this application, the technical terms involved in the embodiments of this application are explained below:

[0037] Transparent satellite relay mode: This refers to a working mode in which signals passing through a satellite are only relayed via frequency conversion without changing the signal format or content.

[0038] Transparent relay satellite: A satellite used in transparent relay mode.

[0039] Satellite regeneration processing mode: This refers to the process where, when a signal passes through a satellite, the satellite receives the signal, processes the signal, extracts the data information, and then transmits it.

[0040] Regeneration processing satellite: A satellite used for satellite regeneration processing mode.

[0041] Low Earth Orbit (LEO) satellites: LEO satellites typically operate in orbits between 300 and 2000 kilometers above the Earth's surface.

[0042] Low Earth Orbit (LEO) satellite constellation: A satellite constellation system consisting of multiple LEO satellites distributed in different orbital planes and operating according to certain rules.

[0043] According to an embodiment of this application, a method embodiment for satellite communication is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0044] Figure 1 This is a flowchart of a satellite communication method according to an embodiment of this application, such as... Figure 1 As shown, the method includes the following steps:

[0045] In step S102, within the first area, the transparent relay satellite and / or regeneration processing satellite in the satellite constellation system receive the first data sent by the terminal equipment and transmit the first data to the ground gateway station and / or ground data station.

[0046] In step S104, within the second area, the satellite constellation system regenerates and processes the second data sent by the satellite receiving terminal equipment, and sends the second data to the ground data station. A ground gateway station is deployed in the first area, but no ground gateway station is deployed in the second area.

[0047] Preferably, there are no inter-satellite links between transparent relay satellites, but there are inter-satellite links between regeneration processing satellites.

[0048] Preferably, the satellite constellation system described above can be a double orbit constellation network or a low-Earth orbit satellite constellation system with more than two orbits. This embodiment does not impose any restrictions on this.

[0049] Figure 2 This is a schematic diagram of a dual-orbit constellation network according to an embodiment of this application, as shown below. Figure 2 As shown, the transparent relay satellites include: transparent relay low-Earth orbit (LEO) satellites, which are networked in polar orbits, and the constellation pattern of the transparent relay LEO satellites includes: the Walker constellation; the regeneration processing satellites include: regeneration processing LEO satellites, which are networked in inclined orbits, and the constellation pattern of the regeneration processing LEO satellites includes: the Walker constellation.

[0050] Several satellite deployment options are provided below.

[0051] 1. Transparent relay satellites are deployed in polar orbits, and regeneration processing satellites are deployed in inclined orbits. In polar orbits, satellites are evenly distributed on each orbital plane, and in inclined orbits, satellites are evenly distributed on each orbital plane.

[0052] 2. Both the transparent relay satellites and the regeneration processing satellites are deployed in inclined orbits. In the inclined orbits, the transparent relay satellites and the regeneration processing satellites are distributed at uniform intervals on each orbital plane.

[0053] 3. Both the transparent relay satellites and the regeneration processing satellites are deployed in polar orbits. In polar orbits, the transparent relay satellites and the regeneration processing satellites are distributed at uniform intervals on each orbital plane.

[0054] 4. Both transparent relay satellites and regeneration processing satellites are deployed in inclined orbits and polar orbits. In both inclined orbits and polar orbits, the transparent relay satellites and regeneration processing satellites are distributed at uniform intervals on each orbital plane.

[0055] As is understandable, a transparent relay satellite is a passive repeater whose main function is to receive signals sent by a ground station and forward them to another ground station or other satellites. During processing, this type of satellite does not alter the signal format; it only amplifies the signal. Because it does not perform signal regeneration, it is called "transparent."

[0056] Transparent relay satellites do not have inter-satellite links. They typically communicate with ground stations, interconnecting with other satellites or communication systems through these ground stations. Regeneration processing satellites are active repeaters that receive, process, and regenerate signals. These satellites have enhanced signal processing capabilities, including signal demodulation and modulation, channel decoding, and error correction. During signal processing, regeneration processing satellites can optimize and adjust signals to improve communication quality. Inter-satellite links can exist between regeneration processing satellites. Inter-satellite links allow direct communication between satellites, enabling more efficient data transmission and network expansion. Inter-satellite links reduce dependence on ground stations, improving communication flexibility and reliability.

[0057] For example, the first region is the area within my country, and the second region is the overseas area. Ground gateway stations are deployed in the area within my country, but not in the overseas area. A ground gateway station is a ground facility used for communication with aerial platforms such as satellites and drones. The main functions of a ground gateway station include: 1. Signal transmission: The ground gateway station is responsible for transmitting data sent by the aerial platform to the ground command center, and also transmitting instructions from the ground command center to the aerial platform. 2. Data processing: The data received by the ground gateway station needs to be processed, analyzed, and stored so that users can obtain the information they need. 3. Monitoring and control: The ground gateway station can monitor and control the aerial platform in real time to ensure its normal operation. 4. Navigation and positioning: The ground gateway station can provide navigation and positioning services to the aerial platform, helping it to fly accurately within a designated area. 5. Emergency communication: In certain special circumstances, the ground gateway station can also serve as an emergency communication facility, providing necessary communication support to the aerial platform.

[0058] Transparent relay LEO satellites lack inter-satellite links and require cooperation with ground gateway stations to provide services to users. Regeneration processing LEO satellites use inter-satellite links for data transmission, with data ultimately being stored on the ground by ground data stations.

[0059] In the first region, ground users (the aforementioned terminal devices) can access the system via transparent relay satellites or regeneration processing satellites. In overseas regions, due to the lack of ground gateway stations, transparent relay satellites cannot provide access; ground users can access the network via regeneration processing satellites, which exchange data with the ground network center through inter-satellite links.

[0060] According to some optional embodiments of this application, in a first region, the transparent relay satellite and / or regeneration processing satellite in the satellite constellation system receives the first data transmitted by the terminal equipment and transmits the first data to the ground gateway station and / or ground data station, which can be achieved by the following method:

[0061] Within the first area, the satellite receiving terminal equipment transparently forwards the first data and transmits the first data to the ground gateway station.

[0062] Within the first area, the regeneration processing satellite receives the first data sent by the terminal equipment and transmits the first data to the ground data station through the inter-satellite link between the regeneration processing satellites.

[0063] In other words, data received by transparent relay satellites or regeneration satellites within the territory can be delivered to ground via ground gateway stations and ground data stations.

[0064] Specifically, ground gateway stations receive data relayed by satellites and convert it into a processable format. Ground data stations receive data transmitted by satellites, decode, store, analyze, and distribute the received data. At ground data stations, data is further processed to meet the needs of specific applications. For example, meteorological data may be used to generate weather forecasts, and Earth observation data may be used for environmental monitoring or resource management.

[0065] On the other hand, in the second region, the second data sent by the regeneration processing satellite receiving terminal equipment in the satellite constellation system and the second data sent to the ground data station can be achieved by the following method: in the second region, the second data sent by the regeneration processing satellite receiving terminal equipment is sent to the ground data station through the inter-satellite link between the regeneration processing satellites.

[0066] In other words, if a regeneration processing satellite receives the second data sent by a terminal device in the second region, it can send the second data to a ground data station through the inter-satellite link between the regeneration processing satellites.

[0067] In summary, combining Figure 3 It is known that transparent relay satellites lack inter-satellite links and require cooperation with ground gateway stations to provide services to users. Regeneration processing low-Earth orbit satellites use inter-satellite links for data transmission, with the data ultimately being delivered to ground data stations. In the first region (domestic region), ground users (the aforementioned terminal devices) can access the system via either transparent relay satellites or regeneration processing satellites. In the second region (overseas region), transparent relay satellites do not receive data sent by terminal devices. They only receive data sent by terminal devices (secondary data) via regeneration processing satellites, which then transmit the data to ground data stations via inter-satellite links. Ground data stations are responsible for receiving, storing, and distributing the data transmitted by the satellites for user use.

[0068] In some optional embodiments of this application, the first data includes network parameters.

[0069] Furthermore, the satellite constellation system receives first data transmitted by terminal equipment in a first area and / or a second area, and transmits the first data to a ground gateway station and / or a ground data station, including the following steps:

[0070] Step S1: Determine whether the first data is transparent transmission data. If the first data is transparent transmission data, send the first data to the target ground gateway station indicated by the network parameters. The target ground gateway station is used to configure the network parameters, obtain the first network parameters, and send the first network parameters to the first target satellite indicated by the first network parameters.

[0071] Understandably, data transmission in satellite communications can be divided into two types: transparent transmission and non-transparent transmission. Transparent transmission means that data is transmitted between the sender and receiver via a satellite link without any alteration or processing. Non-transparent transmission, on the other hand, may involve operations such as data encoding, compression, or encryption.

[0072] To determine if data is being transmitted transparently, the following aspects can be analyzed: 1. Data format: Check if the data format remains unchanged during transmission. If the data format is consistent at the receiving and sending ends, then it is likely transparent transmission. 2. Data processing: Understand whether the satellite communication system performs encoding, compression, or encryption on the data. If these processes are absent, the data is likely being transmitted transparently. 3. Communication protocol: Check whether the communication protocol used supports transparent transmission. Some communication protocols inherently support transparent transmission, such as TCP / IP.

[0073] In step S2, the first target satellite receives the first network parameters and provides the first service to the terminal device based on the first network parameters.

[0074] The terminal device receives signals from the first target satellite. These signals include network parameters, such as frequency band, power level, and modulation method. After receiving the signal, the terminal device needs to decode it to extract useful information. Based on the extracted information, the terminal device can provide services to the user. These services include: 1. Data communication: such as internet access and remote monitoring. 2. Voice communication: making voice calls via satellite phone. 3. Video communication: such as video conferencing and real-time video monitoring. 4. Location services: providing location information using satellite signals.

[0075] Step S3: If the first data is not transparent transmission data, the first data is sent to the target ground management station indicated by the network parameters. The target ground management station is used to configure the network parameters, obtain the second network parameters, and send the second network parameters to the satellite constellation system.

[0076] In step S4, the satellite constellation system regenerates the inter-satellite links between satellites and sends the second network parameters to the second target satellite indicated by the second network parameters.

[0077] In step S5, the second target satellite receives the second network parameters and provides the second service to the terminal device based on the second network parameters.

[0078] The terminal device receives signals from the second target satellite. These signals include network parameters, such as frequency band, power level, and modulation method. After receiving the signal, the terminal device needs to decode it to extract useful information. Based on this extracted information, the terminal device can provide services to the user. These services include: 1. Data communication: such as internet access and remote monitoring. 2. Voice communication: making voice calls via satellite phone. 3. Video communication: such as video conferencing and real-time video monitoring. 4. Location services: providing location information using satellite signals.

[0079] On the other hand, it can also be done through Figure 4 The process shown receives the first data and includes the following steps.

[0080] First, the ground network control center (ground management station) configures the network parameters for the first data.

[0081] Then, the satellite constellation system determines whether the first data is transparent data.

[0082] Secondly, if the first data is not transparent data, the ground network control center configures network parameters, routing information, and other parameters; the ground control center sends the configured network parameters to the satellite constellation system through the satellite communication link; the satellite forwards the configured network parameters through the inter-satellite link; the target satellite receives the network parameters and provides communication services.

[0083] Finally, if the first data is transparent data, network parameters are configured through the ground gateway station, and the configured network parameters are sent to the target satellite in the satellite constellation system to control the target satellite to transmit and receive signals, thereby providing communication services.

[0084] As some optional embodiments of this application, after the first target satellite receives the first network parameters, or after the second target satellite receives the second network parameters, the following steps may also be performed:

[0085] Downlink signal data is sent to the terminal device, whereby the terminal device extracts system messages from the downlink signal data and determines whether the downlink signal data is transparent transmission data based on the system messages.

[0086] When the downlink signal data is transparent transmission data, configure the first parameter in the regeneration processing mode, and after the configuration is completed, access the regeneration processing satellite. The first parameter includes: time and frequency compensation parameters based on the regeneration processing mode.

[0087] In addition, when the downlink signal data is not transparently transmitted, the second parameter in the transparent forwarding mode is configured, and after the configuration is completed, the satellite is accessed. The second parameter includes time and frequency compensation parameters based on the transparent forwarding mode.

[0088] Specifically, the terminal device can be accessed through... Figure 5 The process shown processes the received data. For example... Figure 5 As shown, the terminal device receives downlink signals transmitted by the satellite. The terminal device extracts broadcast messages from the downlink signals and obtains system messages from the broadcast messages. The terminal device determines whether the received downlink signal is transparent data. If so, it configures the time-frequency compensation parameters for transparent mode and connects to the transparent satellite network; if not, it configures the time-frequency compensation parameters for regeneration processing mode and connects to the regeneration processing satellite network.

[0089] In some optional embodiments of this application, the first data is sent to the ground gateway station and / or ground data station, which can be achieved by the following methods:

[0090] The operating mode of the target cell in the satellite constellation system is determined through implicit indication. The target cell includes the current cell used to serve the terminal equipment and neighboring cells adjacent to the current cell. The operating mode includes transparent forwarding mode or regeneration processing mode. Further, based on the operating mode, the first data is transmitted to the ground gateway station and / or ground data station.

[0091] Alternatively, the operating mode of the target cell in the satellite constellation system can be determined by the following methods.

[0092] Receive the identification information of the target cell; if the first character of the identification information is the first character, determine the working mode as transparent forwarding mode, wherein the first character includes: 1; if the first character of the identification information is the second character, determine the working mode as regeneration processing mode, wherein the first character includes: 0.

[0093] Alternatively, the operating mode of the target cell in the satellite constellation system can also be determined by the following methods.

[0094] Receive beam polarization indication information from the target cell; if the beam polarization indication information indicates that the beam adopts left-hand circular polarization, determine the working mode as transparent forwarding mode; if the beam polarization indication information indicates that the beam adopts right-hand circular polarization, determine the working mode as regeneration processing mode.

[0095] Alternatively, the operating mode of the target cell in the satellite constellation system can be determined by the following methods.

[0096] The system receives timing advance parameters configured by the satellite constellation system. If both the general timing advance parameter and the K-Mac parameter are third characters, the operating mode is determined to be regeneration processing mode. If one of the general timing advance parameter and the K-Mac parameter is not a third character, the operating mode is determined to be transparent forwarding mode. If the general timing advance parameter, the general timing advance drift parameter, and the general timing advance drift variation parameter are all third characters, the operating mode is determined to be regeneration processing mode. If none of the general timing advance parameter, the general timing advance drift parameter, and the general timing advance drift variation parameter are third characters, and the K-Mac parameter is not a third character, the operating mode is determined to be transparent forwarding mode, where the third character includes 0.

[0097] In other words, when the value of the parameter commonTA for calculating TA is 0, and the K-Mac parameter is also 0, it indicates regeneration processing mode; if either of these two parameters is non-zero, it indicates transparent forwarding mode. When the parameters commonTA, commonTADrift, and commonTADriftVariance for calculating TA are all 0, it indicates regeneration processing mode; if all parameters are non-zero, and the K-Mac parameter is also non-zero, it indicates transparent forwarding mode.

[0098] Common Time Advance (commonTA) is a parameter used to adjust the time offset of satellite signals arriving at the receiver. In satellite communication systems, multiple receivers may receive satellite signals at inconsistent times due to differences in geographical location and propagation environment. Common Time Advance ensures that all receivers receive satellite signals at the same time, thereby improving signal synchronization. Common Time Advance Drift (commonTADrift) is a parameter describing the degree to which the Common Time Advance parameter changes over time. Due to changes in the satellite signal propagation environment and other factors, the Common Time Advance parameter may change over time. Common Time AdvanceDrift describes the trend and speed of this change. Common Time Advance Drift Variance (commonTADriftVariance) is a parameter describing the degree of uncertainty or fluctuation in the Common Time Advance Drift parameter. Due to the complexity of the satellite signal propagation environment and other factors, the Common Time Advance Drift parameter may have some uncertainty. Common Time Advance Drift Variance describes the degree of this uncertainty.

[0099] It is worth noting that due to certain access restrictions and policy reasons, deploying ground gateway stations for transparent relay satellites in overseas regions is quite difficult. This limits the use of transparent relay satellites in overseas regions. Therefore, this embodiment also provides a cooperative operation and management method for transparent relay low-Earth orbit satellites.

[0100] The main idea of ​​this method includes: configuring transponders with multiple frequency bands and bandwidth combinations on transparent transponder satellites, cooperating with local operators overseas, having local operators deploy gateway stations, and using transparent transponder satellites to provide access services. There are no mandatory requirements on the air interface technology and bandwidth adopted by the operators, as long as they meet the capabilities of the transparent transponder satellite.

[0101] Specifically, in terms of frequency bands: it has the ability to forward multiple frequency bands and is compatible with foreign and overseas IMT operating frequency bands; in terms of signals: it supports independent forwarding and operation of multiple signals, including: 3GPP NTN air interface signals, GMR air interface signals, LTE air interface signals, etc.

[0102] The following example illustrates the process of cooperative operation and management of transparently relayed low-Earth orbit satellites.

[0103] The transparent relay satellite operates in three frequency bands: A, B, and C. These bands are applicable to countries a, b, and c respectively, allowing for deployment in these three countries, which constitute the second region. Due to policy and other factors, ground gateway stations cannot be built in countries b and c, therefore the constellation builders cannot operate the transparent relay satellite independently in these countries. Therefore, cooperation with operators in countries b and c is being considered for operation.

[0104] The cooperative operation methods with country b include the following three: 1. Allowing operators in country b to build ground stations and provide wireless communication services using the B band of the transparent relay satellite; 2. Not imposing requirements on the signal format of operators in country b in the B band, but constraining the uplink and downlink signal strength; 3. Providing operators in country b with parameters such as the ephemeris of the transparent relay low-Earth orbit satellite for joint operation cooperation.

[0105] In addition, the operating time of operators in country b using transparent relay of low-Earth orbit satellites can be statistically analyzed for subsequent billing reference.
