Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a communication method, satellite, network equipment, and terminal equipment. Background Technology

[0002] Satellite internet will become an important part of the future network, and satellite networks are growing in scale. Internet constellations composed of multiple satellites are expected to become an important internet infrastructure in the near future.

[0003] Most satellites operate in the space environment, which contains numerous high-energy particle beams. These high-energy particle beams deposit energy within semiconductor materials and devices, causing damage—a phenomenon known as radiation damage. Radiation damage can lead to device performance degradation or even failure, thereby causing satellite payload and satellite functionality to malfunction.

[0004] Therefore, how to improve the radiation resistance of satellites has become an urgent problem to be solved. Summary of the Invention

[0005] This application provides a communication method, a satellite, a network device, and a terminal device. By acquiring the environmental parameters of the satellite in real time, the satellite's working status is adjusted, thereby improving the satellite's radiation resistance.

[0006] To achieve the above objectives, the embodiments of this application adopt the following technical solutions.

[0007] In a first aspect, embodiments of this application provide a communication method applied to a satellite. The communication method includes: the satellite sending environmental detection data at the current moment to a first device; the satellite receiving prediction information sent by the first device in response to the environmental detection data; the prediction information indicating the radiation intensity of the space environment in which the satellite will be located at the next moment; and the satellite adjusting its operating state based on the prediction information.

[0008] Therefore, in the communication method provided in this application embodiment, the satellite can send environmental detection data of the current moment to the first device in real time. The first device can respond to the environmental detection data to obtain prediction information about the space environment in which the satellite is located at the next moment. Since this prediction information is determined by the first device based on real-time environmental detection data, rather than historical data collected by the satellite, the accuracy of the prediction information is relatively high. In addition, the satellite adjusts its operating state based on this highly accurate prediction information. For example, when the radiation in the space environment is strong, the satellite actively reduces its operating state to improve its radiation resistance, thereby reducing the probability of single-event events, increasing the average lifespan of the constellation composed of multiple satellites, and reducing the constellation deployment cost. For another example, when the radiation in the space environment is weak, the satellite can maintain a highly efficient operating state. In other words, the satellite can improve radiation reliability while ensuring efficient operation.

[0009] In one possible implementation, the satellite includes multiple circuit modules. The satellite adjusts its operating state based on predictive information, including: when the predictive information meets the preset conditions corresponding to the circuit module, the satellite lowers the operating state of the circuit module; when the predictive information does not meet the preset conditions corresponding to the circuit module, the satellite raises the operating state of the circuit module.

[0010] In this implementation, if the predicted information meets the preset conditions corresponding to the circuit module (i.e., strong radiation in the space environment), the satellite reduces its operating status to improve radiation resistance. If the preset information does not meet the preset conditions corresponding to the circuit module (i.e., weak radiation in the space environment), the satellite operates efficiently. Therefore, the satellite can dynamically adjust its operating status based on the predicted information, thereby improving radiation reliability while ensuring high efficiency.

[0011] In one possible implementation, the satellite includes multiple sensors, and before the satellite sends environmental detection data of the current moment to the first device, the communication method further includes: the satellite acquiring environmental detection data through the multiple sensors, the environmental detection data including space environment measurement data.

[0012] In this implementation, a single satellite can acquire space environment measurement data through its multiple sensors. A constellation composed of multiple satellites has the characteristics of a large number of satellites and wide distribution. The constellation can acquire space environment measurement data at different times and in different orbits in real time, which can improve the accuracy of the first device's response to the prediction information sent by the environmental detection data, so that the satellite can adjust its working status based on the prediction information.

[0013] In one possible implementation, the satellite includes multiple sensors, and before the satellite sends the current environmental detection data to the first device, the communication method further includes: the satellite acquiring environmental detection data through the multiple sensors, the environmental detection data including space environment measurement data and solar spectrum measurement data.

[0014] In this implementation, the constellation of multiple satellites not only acquires space environment measurement data at different times and in different orbits, but also acquires solar spectrum measurement data. Taking into account sudden events such as solar flares, it can further improve the accuracy of the first device's response to the predicted information transmitted by the environmental detection data, so that the satellite can adjust its working status based on the predicted information.

[0015] In one possible implementation, the satellite acquires environmental detection data through multiple sensors, including: the satellite acquires environmental detection data in a predetermined area through some of the multiple sensors.

[0016] In this implementation, the preset area can be a region with weak space radiation. In this case, the satellite can acquire environmental detection data through only some sensors to reduce the satellite's power consumption.

[0017] In one possible implementation, the communication method also includes: the satellite forwarding the prediction information to other satellites.

[0018] In this implementation, satellites can act as relay satellites, which forward prediction information to other satellites in the constellation in real time via inter-satellite transmission. This allows all satellites to adjust their operating status based on the prediction information, thereby improving the radiation resistance of all satellites.

[0019] In one possible implementation, the communication method further includes: the satellite sending indication information to the terminal device, the indication information being used to indicate the satellite's operational status.

[0020] In this implementation, the satellite can send indication information to the terminal device to indicate its own working status, so as to ensure the normal operation of the terminal device when the satellite's working status is reduced, thereby improving the satellite's reliability.

[0021] Secondly, embodiments of this application provide a communication method applied to a first device. The communication method includes: the first device receiving environmental detection data sent by multiple satellites; the first device obtaining prediction information based on the environmental detection data and a space environment model; the prediction information being used to indicate the radiation intensity of the space environment in which the satellites will be located at the next moment; and the first device sending the prediction information to the multiple satellites.

[0022] Therefore, in the communication method provided in this application embodiment, since the environmental detection data is acquired in real time by multiple satellites rather than historical data collected by satellites, the accuracy of the prediction information obtained by the first device by inputting the environmental detection data into the space environment model is relatively high. Thus, the satellite can adjust its working state based on the highly accurate prediction information, thereby improving radiation reliability while ensuring efficient operation.

[0023] In one possible implementation, the communication method further includes: the first device updating the space environment model based on environmental detection data.

[0024] In this implementation, since the first device updates the space environment model based on environmental detection data, the accuracy of the prediction information obtained by the first device from inputting environmental detection data into the space environment model can be further improved.

[0025] Thirdly, embodiments of this application provide a communication method applied to a terminal device. The communication method includes: the terminal device receiving indication information sent by a satellite, the indication information indicating the working status of the satellite, and the terminal device switching to a service mode matching the working status of the satellite based on the indication information.

[0026] Therefore, in the communication method provided in this application embodiment, the terminal device can switch service modes according to the working status of the satellite, ensuring the reliability of the terminal device in processing services.

[0027] Fourthly, embodiments of this application provide a satellite, which includes a transmitting module, a receiving module, and an adjustment module. The transmitting module is used to transmit environmental detection data at the current moment to a first device, the receiving module is used to receive prediction information from the first device in response to the transmission of the environmental detection data, the prediction information is used to indicate the radiation intensity of the space environment in which the satellite will be located at the next moment, and the adjustment module adjusts its operating state based on the prediction information.

[0028] In one possible implementation, the satellite includes multiple circuit modules, and the adjustment module is specifically used to: reduce the operating state of the circuit module when the predicted information meets the preset conditions corresponding to the circuit module; and increase the operating state of the circuit module when the predicted information does not meet the preset conditions corresponding to the circuit module.

[0029] In one possible implementation, the satellite also includes multiple sensors for acquiring environmental detection data, including space environment measurement data.

[0030] In one possible implementation, the satellite also includes multiple sensors for acquiring environmental detection data, including space environment measurement data and solar spectrum measurement data.

[0031] In one possible implementation, some of the multiple sensors are used to acquire environmental detection data in a preset area.

[0032] In one possible implementation, the transmitting module is also used to forward prediction information to other satellites.

[0033] In one possible implementation, the transmitting module is also used to send indication information to the terminal device, the indication information being used to indicate the satellite's operational status.

[0034] Fifthly, embodiments of this application provide a first device, which includes a receiving module, a determining module, and a transmitting module. The receiving module is used to receive environmental detection data transmitted by multiple satellites, the determining module is used to obtain prediction information based on the environmental detection data and a space environment model, the prediction information is used to indicate the radiation intensity of the space environment in which the satellite will be located at the next moment, and the transmitting module is used to transmit the prediction information to multiple satellites.

[0035] In one possible implementation, the first device further includes an update module for updating the space environment model based on environmental detection data.

[0036] Sixthly, embodiments of this application provide a terminal device, which includes a receiving module and a switching module. The receiving module is used to receive indication information transmitted by a satellite, the indication information indicating the satellite's operating status, and the switching module is used to switch to a service mode matching the satellite's operating status based on the indication information.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0056] In addition, in the embodiments of this application, descriptions such as "when," "under the circumstances," "if," and "if" all refer to the fact that the device (e.g., a terminal device or a network device) will make corresponding processing under certain objective circumstances. They are not time limits, nor do they require the device (e.g., a terminal device or a network device) to make a judgment action when implementing it, nor do they imply any other limitations.

[0057] It should be noted that, in this application, the terms "exemplary" or "for example" are used to indicate that something is being described as an example, illustration, or illustration. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or design solutions. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0058] The network architecture and business scenarios described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0059] This application will present various aspects, embodiments, or features relating to a system that may include multiple devices, components, modules, etc. It should be understood and appreciated that individual systems may include additional devices, components, modules, etc., and / or may not include all the devices, components, modules, etc. discussed in conjunction with the accompanying drawings. Furthermore, combinations of these approaches may also be used.

[0060] Satellite payload design needs to consider the relationship between the satellite's radiation resistance and lifespan, as well as cost factors. If designers aim for low cost, using commercial off-the-shelf (COTS) payloads has become a design consensus. Improving the radiation resistance of satellite payloads while maintaining commercial value and low cost has become a new engineering requirement. Furthermore, when facing solar storms or years of high solar activity, satellite functions are typically shut down and launch windows are avoided, meaning the satellite cannot provide uninterrupted service.

[0061] The space environment in which satellites operate contains various high-energy particles such as protons, alpha particles, and heavy ions. When these high-energy particles pass through semiconductor devices, they may produce various single-event effects (SEE), such as single-event upset (SEU), single-event transient (SET), and single-event latchup (SEL). SEE may cause abnormal chip operation, thereby generating a single-event functional interrupt (SEFI) of the chip (or circuit).

[0062] Taking single-event upsets (SEE) as an example, an SEE occurs when a single event impacts an integrated circuit, causing the circuit's locked logic state to change from 1 to 0 or from 0 to 1. SEE includes soft flips and single-event hard errors (SEHE). Soft flips are not destructive; most SEE cases are soft flips, and the logic unit can be overwritten or reset. Hard errors, on the other hand, refer to permanent damage to the semiconductor device's dielectric caused by a single event impact; this is an irreversible state.

[0063] Continuing with the single-event transient (SET) example, a SET refers to the instantaneous current pulse generated when a charged particle impacts a combinational logic block. If the combinational logic block operates fast enough and introduces an instantaneous current pulse during propagation, this pulse may be considered a valid signal and thus stored as real data.

[0064] Continuing with the example of single-event latch-up, single-event latch-up refers to a potential or permanent destructive state of an integrated circuit caused by a single-event impact, which triggers a parasitic thyristor structure equivalent to a silicon controlled rectifier, creating a low-impedance, high-current channel.

[0065] Currently, the methods to improve the radiation resistance of satellite payloads typically involve enhancing the radiation resistance of the components or modules that make up the payload. Based on the technological level of improving radiation resistance, radiation hardening schemes can be categorized into the following three types.

[0066] The first category is radiation hardening technology for semiconductor materials and devices. Among these, many radiation-sensitive devices in satellite payloads are semiconductor devices, which are primarily formed from various semiconductor materials. These materials exhibit specific electrical properties under an external electric field to meet engineering requirements. High-energy particles in space can interact with semiconductor materials, causing them and devices to lose their inherent electrical or optical properties, deviating from engineering design requirements and thus generating semiconductor radiation effects. Therefore, semiconductor radiation effects are essentially a series of cascading effects resulting from the interaction between cosmic rays and semiconductor materials. Consequently, the radiation resistance of devices can be improved by modifying the semiconductor material fabrication process or designing the components.

[0067] Taking the laterally diffused metal oxide semiconductor transistor (LDMOS) as an example, such as Figure 1 As shown, Figure 1 The diagram shows a schematic of an LDMOS structure.

[0068] The LDMOS includes a substrate, on which a well 1 and a drift region 2 are formed side-by-side. A SiO2 silicon oxynitride layer 5 and an HTO silicon oxynitride layer 6 are sequentially stacked on the well 1. A polycrystalline gate 7 is formed on the HTO silicon oxynitride layer 6. The interior of the well 1 includes a source doped region 8 and a body lead doped region 9. Multiple field oxides 3 are formed on the drift region 2, with field rings 4 formed between them. A thin SiO2 silicon oxynitride layer 11 is formed on the field rings 4. A dielectric layer 12 is formed on the well 1, polycrystalline gate 7, field oxides 3, and the thin SiO2 silicon oxynitride layer 11. A drain doped region 10 is also formed on the drift region 2. The SiO2 silicon oxynitride layer 5 is formed by nitriding the SiO2 gate oxide layer, and the thickness of the SiO2 silicon oxynitride layer 5 ranges from [insert thickness range here]. The HTO silicon oxynitride layer 6 is formed by nitriding the HTO gate oxide layer. The thickness of the HTO silicon oxynitride layer 6 ranges from [missing information]. The SiO2 silicon oxynitride layer 5 and the HTO silicon oxynitride layer 6 constitute a radiation-hardened composite gate structure. The SiO2 thin silicon oxynitride layer 11 is formed by nitriding a thin SiO2 oxide layer. The thickness of the SiO2 thin silicon oxynitride layer 11 ranges from [missing information].

[0069] This LDMOS transistor utilizes a composite gate dielectric structure and a drift region hardening process. The composite gate dielectric reduces the change in threshold voltage before and after total dose radiation and increases the single-particle gate string threshold. Nitriding transforms the Si-H bonds and Si dangling bonds in the original SiO2 gate oxide layer into stronger Si-N bonds, forming silicon oxynitride, thereby improving the radiation resistance of the gate oxide. Simultaneously, the drift region hardening process reduces the degradation of breakdown voltage after total dose radiation, significantly enhancing the reliability of LDMOS devices in space radiation environments.

[0070] Radiation hardening technology for semiconductor materials and devices can be applied to all devices, but this technology requires redesigning the semiconductor material and device process structure, which necessitates significant changes to the production line, resulting in high costs. Furthermore, the performance of the redesigned devices cannot reach the same level as existing devices.

[0071] The second category is radiation hardening technology for devices and functional modules. In this category, components are packaged into device modules through a series of topological connections, such as switching regulators, flash memory, and clock mixers. These modules have specific functions. High-energy particles in the universe interact with sensitive components within these modules, generating transient currents that propagate through the device topology, ultimately causing the module's function to deviate from its design values ​​and leading to malfunctions. Therefore, based on the principle of device radiation effects, the radiation resistance of device modules can be improved by rationally designing the device topology.

[0072] Taking a low dropout regulator (LDO) as an example, such as Figure 2 As shown, Figure 2 The diagram shows a schematic of an LDO.

[0073] The LDO may include adjustment module 1, adjustment module 2, differential amplifier circuit 1, differential amplifier circuit 2, reference signal module 1, reference signal module 2, and a sensing module. Adjustment module 1 and adjustment module 2 are both P-channel metal-oxide-semiconductor (PMOS). The input terminal of adjustment module 1 is the input terminal V_IN of the LDO, and the output terminal of adjustment module 2 is the output terminal V_OUT of the LDO. The sensing module includes resistors R1 and R2. One end of resistor R1 is connected to the output terminal V_OUT of the LDO, and one end of resistor R1 is connected to one end of resistor R2. The other end of resistor R2 is grounded. One input terminal of differential amplifier circuit 1 and differential amplifier circuit 2 is connected to the intermediate node between resistors R1 and R2, respectively. The other input terminal of differential amplifier circuit 1 is connected to reference signal module 1, and the other input terminal of differential amplifier circuit 2 is connected to reference signal module 2. The output terminal of differential amplifier circuit 1 is connected to the input terminal of adjustment module 1, and the output terminal of differential amplifier circuit 2 is connected to the input terminal of adjustment module 2. In addition, the output terminal V_OUT is grounded through capacitor C1.

[0074] In this LDO, the output of the differential amplifier circuit and the input of the adjustment module are connected one-to-one. When the components in the LDO experience single-event effects in a radiated environment, the adjustment module can adjust the electrical signal in the LDO based on the feedback signal from the differential amplifier circuit. This eliminates signal fluctuations caused by single-event effects, allowing the LDO to output a stable electrical signal. This effectively improves the LDO's radiation resistance and thus its reliability.

[0075] Radiation hardening technology for devices and functional modules can be applied to some devices, but this technology also requires redesigning the device topology, changing the layout, increasing device manufacturing costs, and the performance of the redesigned devices cannot reach the same level as existing devices.

[0076] The third category is circuit system-level radiation hardening technology. Unlike the first two types, circuit system-level radiation hardening technology allows the components and modules in the circuit system to experience radiation effects, but ensures that the overall operating state of the circuit system is not affected by radiation through circuit system design, thereby improving the radiation resistance of the components.

[0077] Taking a radio platform as an example, such as Figure 3 As shown, Figure 3The diagram illustrates a system architecture of a radio platform. The radio platform includes a system control unit and three subsystems—a first subsystem, a second subsystem, and a third subsystem—each connected to the system control unit. The system control unit, implemented on a field-programmable gate array (FPGA) chip, acquires the operational status of the first, second, and third subsystems and receives external commands to control them.

[0078] The first, second, and third subsystems are identical. The system control unit is implemented on an FPGA chip. Each subsystem consists of a digital signal processing (DSP) chip and an FPGA, connected to the system control unit. In other words, the radio platform adopts a "2 parallel + 1 backup" structure: two DSP chips process tasks in parallel, while the third DSP chip serves as a backup. When an unrecoverable failure occurs in a parallel-operating DSP chip, the backup DSP chip replaces the faulty one, improving the overall reliability of the system.

[0079] Circuit system-level radiation hardening technology can directly use existing devices, but this technology also requires redesigning the system architecture, has poor protection against destructive radiation damage, generates significant redundancy and additional overhead, has high costs, and reduces system performance.

[0080] Therefore, this application provides a communication method that can improve the radiation resistance of satellites. In this method, the satellite can send environmental detection data to a network device in real time. The network device can respond to this environmental detection data to obtain prediction information about the next moment of the space environment in which the satellite is located. Since this prediction information is determined by the network device based on real-time environmental detection data, rather than historical data collected by the satellite, the accuracy of the prediction information is high. In addition, the satellite can adjust its operating state based on the prediction information. For example, when the radiation in the space environment is strong, the satellite can actively adjust its operating state to improve its radiation resistance, reduce the probability of single-event events, increase the average lifespan of a constellation composed of multiple satellites, and reduce the deployment cost of the constellation. For another example, when the radiation in the space environment is weak, the satellite can maintain an efficient operating state. In other words, the satellite can improve radiation reliability while ensuring efficient operation.

[0081] For ease of understanding, the communication system used in the communication method provided in the embodiments of this application will be introduced below.

[0082] The technical solutions of this application can be applied to various communication systems, such as wireless fidelity (Wi-Fi) systems, vehicle-to-everything (V2X) communication systems, device-to-device (D2D) communication systems, vehicle-to-everything (V2X) communication systems, 4th generation (4G) mobile communication systems, such as long term evolution (LTE) systems, worldwide interoperability for microwave access (WiMAX) communication systems, 5th generation (5G) mobile communication systems, such as new radio (NR) systems, and future communication systems.

The network device in this application can also be a logical node, logical module, or software capable of implementing all or part of the functions of a network device.

[0086] In another possible scenario, multiple RAN nodes collaborate to assist terminal devices in achieving wireless access, with different RAN nodes each implementing a portion of the base station's functions. For example, RAN nodes can be central units (CUs), distributed units (DUs), CU-control plane (CPs), CU-user plane (UPs), or radio units (RUs), etc. CUs and DUs can be set up separately or included in the same network element, such as a baseband unit (BBU). RUs can be included in radio frequency equipment or radio frequency units, such as remote radio units (RRUs), active antenna units (AAUs), or remote radio heads (RRHs).

[0087] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an ORAN system, CU can also be called O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules.

[0088] As mentioned above, all or part of the functional modules of a network device can be deployed on an airborne platform or satellite, or other forms of communication equipment deployed in the high atmosphere. Accordingly, network equipment can refer to an airborne platform, satellite, or other similar equipment that connects terminal devices to the network device. An airborne platform can include at least one of the following: a satellite, an aircraft, a drone, or a hot air balloon.

The device can be installed in the network device or used in conjunction with the network device.

[0090] In this application embodiment, the terminal device is a terminal that accesses the aforementioned communication system and has wireless transceiver functionality, or a chip or chip system that can be installed in the terminal. This terminal device can also be referred to as user equipment (UE), user device, access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user device.

The vehicle can implement the method provided in this application through the built-in on-board module, on-board component, on-board chip, or on-board unit.

[0091] The embodiments of this application do not limit the device form of the terminal device.

The ground-based data center integrates the network's core routers and core switches, undertaking functions such as data transmission, routing, and flow control. In some embodiments, the first device may also be a server cluster or a supercomputing device.

[0093] It should be noted that the solutions in the embodiments of this application can also be applied to other communication systems, and the corresponding names can be replaced by the names of the corresponding functions in other communication systems.

[0094] The communication method provided in the embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0095] This application provides a communication method, such as... Figure 5 As shown, Figure 5 The diagram illustrates a flowchart of a communication method. This communication method uses... Figure 4 The communication between the network device (i.e., the satellite) and the first device is illustrated using this method as an example. Of course, the subject executing the action of the first device in this method can also be a device / module in the first device, such as a chip, processor, or processing unit in the first device; the subject executing the action of the network device in this method can also be a device / module in the network device, such as a chip, processor, or processing unit in the network device, and this application embodiment does not specifically limit this.

[0096] like Figure 5 As shown, the communication method includes the following process.

[0097] S501, The satellite transmits the current environmental detection data to the first device. Correspondingly, the first device receives environmental detection data transmitted by multiple satellites.

[0098] For example, environmental detection data is also called energy spectrum data, which is the number of high-energy particles with different energies.

[0099] For example, a satellite can be a satellite that includes "sensing" capabilities, meaning it can acquire environmental detection data but does not process it. A satellite can also be a satellite that includes both "sensing" and "knowing" capabilities, meaning it can acquire and process environmental detection data.

[0100] For example, multiple satellites form a constellation, which may include multiple satellites with sensing capabilities. These sensing satellites can convert environmental detection data into space energy spectra through various detection schemes, thereby obtaining energy spectrum data at different orbits and times in space, and summarizing them into an orbital energy spectrum image database.

[0101] Optionally, the satellite includes multiple sensors. Prior to S501, the communication method also included: the satellite acquiring environmental detection data through multiple sensors, including space environment measurement data.

[0102] For example, multiple sensors can also be called high-energy particle detection devices. High-energy particle detection devices can detect the energy and number of radiating particles. High-energy particle detection devices can also detect single-event flip effects, single-event transient effects, single-event latch-up effects, or single-event burn-out effects to obtain a variety of radiation effects.

[0103] Specifically, high-energy particle detectors operate on the principle of different types of matter interaction mechanisms. When high-energy particles pass through materials, they leave traces or trigger reactions, such as exciting or ionizing the surrounding medium. In one possible example, photons might be scattered or absorbed to produce secondary electrons, while neutrinos might participate in weak interactions, and so on.

[0104] Therefore, a single satellite can acquire space environment measurement data through its multiple sensors. A constellation composed of multiple satellites has the characteristics of a large number of satellites and wide distribution. The constellation can acquire space environment measurement data at different times and in different orbits in real time, which can improve the accuracy of the first device's response to the prediction information sent by the environmental detection data, so that the satellite can adjust its working status based on the prediction information.

[0105] Optionally, the satellite includes multiple sensors. Prior to S501, the communication method also included: the satellite acquiring environmental detection data through multiple sensors, including space environment measurement data and solar spectrum measurement data.

[0106] For example, in addition to the high-energy particle detection device described above, multiple sensors may also include X-ray to gamma-ray spectrometers (also known as spectral sensing devices). Spectrometers can acquire data on the Sun's internal structure and the dynamic processes occurring on its surface to obtain solar spectral measurement data. Specifically, spectrometers can acquire characteristics such as temperature, density, and chemical composition at different levels of the Sun's atmosphere. When light passes through matter, it absorbs or emits specific wavelengths; these characteristics can be captured by the spectrometer to form unique spectral line patterns.

[0107] Therefore, in addition to acquiring space environment measurement data at different times and in different orbits, the constellation also acquires solar spectrum measurement data. Taking into account sudden events such as solar flares, it can further improve the accuracy of the first device's response to the transmission of environmental detection data, so that the satellite can adjust its working status based on the prediction information.

[0108] For example, space environment measurement data and solar spectrum measurement data can be transmitted through a dedicated data channel. Alternatively, space environment measurement data and solar spectrum measurement data can also be transmitted through an operational data link, in which case they can be identified by indicator bits.

[0109] Optionally, the satellite acquires environmental detection data through multiple sensors, including: the satellite acquires environmental detection data in a preset area through some of the multiple sensors.

[0110] For example, the preset area can be a region with weak space radiation. Specifically, within the satellite's orbit, in the absence of special events, the satellite can determine the range of areas with varying space radiation intensity, i.e., the preset area. Of course, when special events occur (such as a solar event), the range of areas with varying space radiation intensity will change dynamically.

[0111] For example, in areas with strong space radiation, when a satellite is located in that area, it can acquire environmental detection data through all its sensors to improve the accuracy of the environmental detection data and ensure that the satellite can respond quickly.

[0112] For example, in areas with weak space radiation, i.e., a predetermined area, when the satellite is in this area, it can acquire environmental detection data using only some of its sensors to reduce satellite power consumption. After the satellite passes through the area, it then acquires environmental detection data using all its sensors to improve the accuracy of the environmental detection data and ensure that the satellite can respond quickly.

[0113] In one possible scenario, when a satellite's optical sensors detect a solar event, even if the satellite is located in a pre-defined area, it will need to acquire environmental detection data through all its sensors to improve the accuracy of the environmental detection data and ensure that the satellite can respond quickly.

[0114] S502, The first device obtains prediction information based on environmental detection data and space environment model.

[0115] The prediction information is used to indicate the radiation intensity of the space environment in which the satellite will be located at the next moment.

[0116] For example, the first device can perform modeling calculations on the space environment to obtain a space environment model. In one possible example, the space environment model could be a model of the effects of cosmic rays on micro-electronics (CREME96) published in 1996, a space radiation model, or other types of models; this application embodiment does not limit this to any particular type.

[0117] For example, the first device can input environmental detection data into a space environment model to obtain the predicted information output by the space environment model. In this embodiment of the application, environmental detection data acquired by multiple satellites are calculated by the first device on the ground, realizing a system of on-board measurement and ground calculation, which can improve the efficiency of on-board calculation.

[0118] It is understood that in the communication method provided in the embodiments of this application, the prediction information can also be calculated by satellite to improve the calculation efficiency.

[0119] Optionally, the first device updates the space environment model based on environmental detection data.

[0120] For example, after receiving environmental detection data each time, the first device can update the space environment model based on the environmental detection data to further improve the accuracy of the prediction information obtained by the space environment model based on the environmental detection data.

[0121] S503, the first device sends prediction information to multiple satellites. Correspondingly, the satellites receive the prediction information sent by the first device in response to environmental monitoring data.

[0122] For example, the prediction information may include prediction information for each satellite, and the first device may directly send the prediction information corresponding to each satellite to each satellite.

[0123] Optionally, the communication method also includes: the satellite forwarding the prediction information to other satellites.

[0124] In other words, the first device can also indirectly send prediction information to multiple satellites. For example, the first device can send prediction information to other satellites through relay devices such as space relays (e.g., relay satellites) or ground relays (e.g., base stations) so that all satellites can obtain prediction information, that is, all satellites have the ability to perceive the space radiation environment.

[0125] In one possible example, such as Figure 6 As shown, Figure 6 The diagram shows an interaction between a first device and multiple satellites. Figure 6 The diagram specifically illustrates a first device and multiple satellites, such as Satellite 1, Satellite 2, and Satellite 3. The first device receives environmental detection data from Satellite 1, Satellite 2, and Satellite 3. The first device then sends predictive information about Satellites 1, 2, and 3 obtained in response to the environmental detection data to Satellite 2. Satellite 2 acts as a relay satellite, forwarding the corresponding predictive information to Satellites 1 and 3. Thus, Satellites 1, 2, and 3 all possess space radiation sensing capabilities and can adjust their operational status to balance efficient operation with high radiation resistance.

[0126] In another possible example, such as Figure 7 As shown, Figure 7 The diagram illustrates the interaction between multiple satellites. Figure 7 The diagram specifically illustrates satellite 1 and satellite 2. Satellite 1 activates its sensors at a first position to acquire environmental detection data and transmits this data to a first device in real time. After time t, satellite 1 reaches a second position, receives prediction information from the first device in response to the environmental detection data transmission, and forwards the prediction information from satellite 2 to satellite 2.

[0127] S504. The satellite adjusts its operational status based on predictive information.

[0128] For example, the satellite can conduct ground reliability evaluation experiments to obtain a reliability database, which may include operational status data from the whole satellite level to the module level. The satellite may support adaptive derating or remote control.

[0129] Optionally, the satellite includes multiple circuit modules, and S504 may include: when the prediction information meets the preset conditions corresponding to the circuit module, the satellite lowers the operating state of the circuit module; when the prediction information does not meet the preset conditions corresponding to the circuit module, the satellite raises the operating state of the circuit module.

[0130] For example, reducing the operating status of a satellite's circuit module can be referred to as system derating. The content of the derating varies for different circuit modules.

[0131] Taking the circuit module as the power supply as an example, such as Figure 8 As shown, Figure 8 The diagram illustrates the structure of a power supply system. The power supply system includes a secondary power supply and multiple tertiary power supplies, such as tertiary power supply_1, tertiary power supply_2, tertiary power supply_3, and tertiary power supply_4. Tertiary power supply_2 supplies power to the graphics processing unit (GPU), and tertiary power supply_4 supplies power to the analog-to-digital converter (ADC).

[0132] By performing single-event burn-out assessment on each power source, the single-event burn-out probability function for each power source can be obtained, which represents the preset conditions for each power source. The single-event burn-out probability function is related to at least one of the following conditions: input voltage, output voltage, operating current, maximum operating voltage, maximum operating current, operating temperature, particle energy, and particle flux.

[0133] For example, the secondary power supply is typically high-voltage, and its input voltage is the satellite bus voltage (which cannot be adjusted) when the secondary power supply is operating. The input voltage of the secondary power supply can be 48V to 60V. Because the input voltage of the secondary power supply is relatively high, the corresponding single-event burn-up probability function has high voltage requirements. When the radiation environment characterized by the prediction information received by the satellite meets the preset conditions corresponding to the secondary power supply, the secondary power supply needs to be shut down until a safe area is reached where the radiation environment characterized by the prediction information does not meet the preset conditions corresponding to the secondary power supply.

[0134] For example, the tertiary power supply_2 provides low-voltage, high-current power. Its operating voltage is related to the design requirements of the backend chip, while its operating current is related to the operational status of the backend chip. Because the operating current of the tertiary power supply_2 is relatively high, the corresponding single-event burn-out function requires a higher current. When the radiation environment characterized by the predicted information received by the satellite meets the preset conditions corresponding to the tertiary power supply_2, the satellite can, based on the radiation environment conditions, shut down some services of the backend chip to reduce its power consumption. Alternatively, the satellite can also shut down the tertiary power supply_2 until it reaches a safe area where the radiation environment characterized by the predicted information no longer meets the preset conditions corresponding to the tertiary power supply_2.

[0135] For example, the tertiary power supply_4 can be used to power an analog-to-digital converter (ADC). The single-event transients generated by radiation can cause the ADC to produce a large amount of erroneous data, thus requiring high-precision power supply_4. When the radiation environment characterized by the predictive information received by the satellite meets the conditions of the tertiary power supply_4, its operating mode can be adjusted to reduce bit errors. Taking tertiary power supply_2 as an example... Figure 2 Taking the LDO shown as an example, the adjustment module in the third power supply_4 adjusts the electrical signal in the third power supply_4 according to the feedback signal output by the differential amplifier circuit, so as to eliminate the electrical signal fluctuation caused by the single event effect in the third power supply_4 and output a stable electrical signal.

[0136] Taking a circuit module as an example of a chip system, such as Figure 9 As shown, Figure 9 The diagram illustrates the structure of a chip system. The chip system may include a field-programmable gate array (FPGA) and multiple flash memories, including flash memory 1 and flash memory 2. The FPGA includes multiple random access memories (RAMs), such as RAM1, RAM2, RAM3, and RAM4.

[0137] By performing single-event burn-out assessment on each chip, the single-event burn-out probability function of each chip can be obtained, which represents the preset conditions for each chip. The single-event burn-out probability function is related to at least one of the following conditions: number of resources, power consumption, operating voltage, operating current, maximum operating voltage, maximum operating current, operating temperature, particle energy, and particle flux.

[0138] For example, flash memory accumulates bit flips during operation, leading to code errors in critical programs, and is more prone to burnout during read / write operations. When the radiation environment characterized by satellite-received predictive information meets the preset conditions corresponding to the flash memory, frequent read / write operations and timed refreshes can be stopped to protect the reliability of the flash memory device and critical information.

[0139] For example, when the radiation environment characterized by the predictive information received by the satellite meets the preset conditions corresponding to the FPGA, the power supply to the FPGA can be stopped to protect the FPGA device.

[0140] For example, bit flipping in RAM can cause errors in the running program and stored information. When the radiation environment represented by the satellite-received prediction information meets the preset conditions corresponding to the RAM, protective measures can be taken to protect the RAM. These protective measures include error checking and correction (ECC) and triple-mode redundancy. When the radiation environment represented by the satellite-received prediction information does not meet the preset conditions corresponding to the RAM, the protective measures can be canceled to obtain better performance.

[0141] Therefore, in the communication method provided in this application embodiment, the constellation can improve its anti-radiation capability by acquiring environmental detection data, self-sensing, environmental prediction, and system derating, thereby increasing the average lifespan of the constellation and reducing the constellation deployment cost.

[0142] This application also provides a communication method, such as... Figure 10 As shown, Figure 10 The diagram illustrates a flowchart of another communication method. This communication method uses... Figure 4 The communication between the network device (i.e., satellite) and the terminal device is illustrated using the example shown. Of course, the entity performing the network device action in this method can also be a device / module in the network device, such as a chip, processor, or processing unit in the network device; the entity performing the terminal device action in this method can also be a device / module in the terminal device, such as a chip, processor, or processing unit in the terminal device. This application does not specifically limit this aspect.

[0143] like Figure 10 As shown, the communication method includes the following process.

[0144] S1001. The satellite sends instruction information to the terminal device. Correspondingly, the terminal device receives the instruction information sent by the satellite.

[0145] The indication information is used to indicate the satellite's operational status.

[0146] For example, when the satellite's operating status changes, the satellite also needs to send indication information to the terminal equipment to alert the terminal equipment and improve the reliability of satellite services.

[0147] For example, satellites and terminal devices can transmit instruction information through a dedicated data channel, or they can transmit it through a business data link, in which case they can be identified by a dedicated identifier.

[0148] S1002. The terminal device switches to a service mode that matches the satellite's operating status based on the instruction information.

[0149] For example, if the satellite is in a protected state, the terminal device can switch to a service mode that matches the protected state. In one possible example, if the terminal device receives an indication that the satellite is in a protected state, the terminal device can suspend communication with the satellite. When the terminal device receives an indication that the satellite is in a normal operating state, the terminal device can resume communication with the satellite.
