Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a method for testing a broadband communication payload, a satellite communication system, a program product, an electronic device, and a storage medium. Background Art

[0002] Satellite communication systems consist of a space segment, a ground segment, and a user segment. The space segment primarily refers to in-orbit satellites; the ground segment typically includes gateways, control centers (such as network control centers and satellite control centers), tracking and control stations, and a ground support network, used to connect mobile users to the core network and perform tracking and control of the space segment. Before a feeder link is successfully established between an in-orbit satellite and a gateway, communication between the in-orbit satellite and the ground is limited to the tracking and control link. The commonly used process for remote control and telemetry commands for broadband communication payloads is as follows: the control center sends remote control commands via the tracking and control station, which are received by the integrated electronics on the in-orbit satellite and forwarded to the broadband communication payload. The integrated electronics periodically queries the broadband communication payload for telemetry information, which is then sent to the tracking and control station via the tracking and control link. The tracking and control station then forwards the telemetry information to the control center.

[0003] Current remote control and telemetry commands for broadband communication payloads primarily focus on the payload's hardware status and startup and operation control, lacking testing and verification for communication payloads conforming to non-terrestrial networks (NTN) standards. The NTN standard's communication architecture design encompasses a wide range of aspects, encompassing not only protocol-related processing layers such as Radio Resource Control (RRC), Media Access Control (MAC), Radio Link Control (RLC), Packet Data Convergence Protocol (PDCP), Service Data Adaptation Protocol (SDAP), and the physical layer, but also intermediate frequency (IF) digital front-end processing, Common Public Radio Interface (CRPI), and beam control. However, implementing this massive number of test items using existing technologies results in the measurement and control link being unable to carry the corresponding data. Summary of the Invention

[0004] The purpose of the embodiments of the present application is to provide a method for solving the technical problem in the prior art that a large number of test items may cause the measurement and control link to be unable to carry the corresponding data transmission.

[0005] In a first aspect, an embodiment of the present application provides a method for testing a broadband communication load, which is applied to a broadband communication load. The method for testing the broadband communication load includes: receiving a load test instruction, wherein the load test instruction includes at least one configuration field, and different configuration fields are used to instruct the broadband communication load to perform different test operations; parsing the load test instruction based on a pre-stored broadband communication load test protocol to obtain a corresponding parsing result; and executing a test operation corresponding to the configuration field according to the parsing result.

[0006] In the above scheme, different test operations are integrated into a single payload test instruction through configuration fields. Simultaneously, the payload test instruction is parsed using a pre-stored broadband communication payload test protocol. This allows the broadband communication payload to perform functions such as service control, data transmission, and protocol system parameter verification. This overcomes the limitation of traditional instructions that can only perform a single function, enabling the broadband communication payload to perform diverse tests, thereby reducing the number of instructions, improving test efficiency, and minimizing the impact on the measurement and control station and integrated electronics. Therefore, the broadband communication payload testing method provided in the embodiments of the present application can solve the technical problem in the prior art where the measurement and control link cannot carry the corresponding data transmission.

[0007] In an optional embodiment, the load test instruction also includes an instruction header, the instruction header including an instruction code and an instruction length, the instruction code is used to indicate the type of the load test instruction, and the instruction length is used to indicate the length of the load test instruction; the load test instruction is parsed based on the pre-stored broadband communication load test protocol to obtain a corresponding parsing result, including: determining the type of the load test instruction according to the instruction code, and comparing whether the instruction length is consistent with the length of the load test instruction; determining the parameters corresponding to the test operation according to the configuration field.

[0008] In the above scheme, the standardized design of the instruction header can simplify the parsing process, allowing broadband communication payloads to quickly identify instruction types, thereby reducing processing latency; the instruction length field reserves space for future expansion configuration fields, and new test functions can be added without modifying the basic instruction format, ensuring the system's compatibility with protocol evolution.

[0009] In an optional embodiment, if the test operation includes collecting test information, then after performing the test operation corresponding to the configuration field according to the analysis result, the test method of the broadband communication load also includes: after completing the test operation, sending feedback information corresponding to the load test instruction; receiving a load information collection instruction; encapsulating the collected load test information into telemetry data, and sending the telemetry data.

[0010] In this solution, feedback confirms the status of operational execution. Combining information collection with telemetry data transmission ensures the control center has real-time visibility into load status, improving fault location and repair efficiency. Furthermore, according to the principle of time-sharing multiplexing, information collection is triggered on demand after the test operation is executed, avoiding continuous bandwidth usage and alleviating the strain on measurement and control resources found in traditional methods.

[0011] In an optional embodiment, the telemetry data includes fixed telemetry items and custom telemetry items.

[0012] In this solution, fixed telemetry items ensure basic status monitoring, while custom telemetry items allow for dynamic adjustment of collected data without modifying hardware or reconfiguring the instruction set, significantly reducing the cost of on-orbit satellite upgrades. Furthermore, the broadband communication payload's communication system telemetry data collection is decoupled from the integrated electronics, freeing the integrated electronics from the communication system's operational implementation, reducing development workload and subsequent maintenance costs.

[0013] In the second aspect, an embodiment of the present application provides a method for testing a broadband communication load, which is applied to a control center. The method for testing the broadband communication load includes: sending a load test instruction, wherein the load test instruction includes at least one configuration field, and different configuration fields are used to instruct the broadband communication load to perform different test operations; receiving feedback information corresponding to the load test instruction, wherein the feedback information is used to instruct the broadband communication load to complete the test operation.

[0014] In the above scheme, different test operations are integrated into a single payload test instruction through configuration fields. Simultaneously, the payload test instruction is parsed using a pre-stored broadband communication payload test protocol. This allows the broadband communication payload to perform functions such as service control, data transmission, and protocol system parameter verification. This overcomes the limitation of traditional instructions that can only perform a single function, enabling the broadband communication payload to perform diverse tests, thereby reducing the number of instructions, improving test efficiency, and minimizing the impact on the measurement and control station and integrated electronics. Therefore, the broadband communication payload testing method provided in the embodiments of the present application can solve the technical problem in the prior art where the measurement and control link cannot carry the corresponding data transmission.

[0015] In an optional embodiment, the load test instruction further includes an instruction header, which includes an instruction code and an instruction length, wherein the instruction code is used to indicate the type of the load test instruction, and the instruction length is used to indicate the length of the load test instruction.

[0016] In the above scheme, the standardized design of the instruction header can simplify the parsing process, allowing broadband communication payloads to quickly identify instruction types, thereby reducing processing latency; the instruction length field reserves space for future expansion configuration fields, and new test functions can be added without modifying the basic instruction format, ensuring the system's compatibility with protocol evolution.

[0017] In an optional embodiment, if the test operation includes collecting test information, then after receiving feedback information corresponding to the load test instruction, the broadband communication load testing method also includes: sending a load information collection instruction; and receiving telemetry data corresponding to the load information collection instruction.

[0018] In this solution, feedback confirms the status of operational execution. Combining information collection with telemetry data transmission ensures the control center has real-time visibility into load status, improving fault location and repair efficiency. Furthermore, according to the principle of time-sharing multiplexing, information collection is triggered on demand after the test operation is executed, avoiding continuous bandwidth usage and alleviating the strain on measurement and control resources found in traditional methods.

[0019] In an optional embodiment, the telemetry data includes fixed telemetry items and custom telemetry items.

[0020] In this solution, fixed telemetry items ensure basic status monitoring, while custom telemetry items allow for dynamic adjustment of collected data without modifying hardware or reconfiguring the instruction set, significantly reducing the cost of on-orbit satellite upgrades. Furthermore, the broadband communication payload's communication system telemetry data collection is decoupled from the integrated electronics, freeing the integrated electronics from the communication system's operational implementation, reducing development workload and subsequent maintenance costs.

[0022] In the above scheme, different test operations are integrated into a single payload test instruction through configuration fields. Simultaneously, the payload test instruction is parsed using a pre-stored broadband communication payload test protocol. This allows the broadband communication payload to perform functions such as service control, data transmission, and protocol system parameter verification.

Therefore, the broadband communication payload testing method provided in the embodiments of the present application can solve the technical problem in the prior art where the measurement and control link cannot carry the corresponding data transmission.

[0023] In an optional embodiment, the load test instruction also includes an instruction header, the instruction header includes an instruction code and an instruction length, the instruction code is used to indicate the type of the load test instruction, and the instruction length is used to indicate the length of the load test instruction; the parsing module is specifically used to: determine the type of the load test instruction according to the instruction code, and compare whether the instruction length is consistent with the length of the load test instruction; determine the parameters corresponding to the test operation according to the configuration field.

[0024] In the above scheme, the standardized design of the instruction header can simplify the parsing process, allowing broadband communication payloads to quickly identify instruction types, thereby reducing processing latency; the instruction length field reserves space for future expansion configuration fields, and new test functions can be added without modifying the basic instruction format, ensuring the system's compatibility with protocol evolution.

[0025] In an optional embodiment, if the test operation includes collecting test information, the test device for the broadband communication load also includes: a first sending module, used to send feedback information corresponding to the load test instruction after completing the test operation; a second receiving module, used to receive the load information collection instruction; encapsulate the collected load test information into telemetry data, and send the telemetry data.

[0026] In this solution, feedback confirms the status of operational execution. Combining information collection with telemetry data transmission ensures the control center has real-time visibility into load status, improving fault location and repair efficiency. Furthermore, according to the principle of time-sharing multiplexing, information collection is triggered on demand after the test operation is executed, avoiding continuous bandwidth usage and alleviating the strain on measurement and control resources found in traditional methods.

[0027] In an optional embodiment, the telemetry data includes fixed telemetry items and custom telemetry items.

Any embodiment or design described in this application as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0046] Before describing the technical solutions of the embodiments of this application, we first explain the satellite communication system of the embodiments of this application. The satellite communication system includes a space segment, a ground segment, and a user segment. The space segment includes satellites; the ground segment includes a gateway, a control center, a measurement and control station, and a ground support network, which is used to connect mobile users to the core network and perform measurement and control functions for the space segment; and the user end includes fixed terminals and mobile terminals.

[0047] As an implementation method, please refer to Figure 1 , Figure 1 A schematic structural diagram of a satellite communication system provided in an embodiment of the present application, wherein the satellite communication system includes: a satellite, a control center, and a measurement and control station.

[0048] The control center can include a satellite control center and a network control center. The satellite control center is responsible for on-orbit management of the satellite platform, including orbit adjustment, attitude control, power supply and thermal control monitoring, etc., to ensure stable satellite operation. The network control center is the brain of the low-orbit satellite system and is responsible for the overall scheduling of broadband communication services, including resource allocation (such as beam resources and frequency band resources), user access management, and service quality monitoring. In the embodiment of the present application, the control center is used to execute a broadband communication payload testing method provided in the embodiment of the present application. The specific implementation method will be detailed in subsequent embodiments and will not be described here.

[0049] These tracking and control stations are located at ground sites around the globe and establish physical communication with satellites via tracking and control links. They handle tasks such as signal transmission and reception, satellite tracking (compensating for Doppler frequency deviation and beam pointing changes caused by the high-speed movement of low-orbit satellites), and RF signal modulation and demodulation. In this embodiment of the present application, the tracking and control stations are connected to the control center and the satellites, forwarding data from the control center to the satellites and vice versa.

[0050] The above-mentioned satellite acts as a space communication relay node, directly carrying broadband communication services and executing test instructions from the control center; in the embodiment of the present application, the satellite may include integrated electronics and broadband communication payloads. The integrated electronics are communicatively connected to the measurement and control station and the broadband communication payload, and are used to undertake tasks such as ground command forwarding, satellite platform status monitoring, and interface adaptation between the payload and the satellite-to-ground link. It is a transit station for communication between the space segment and the ground segment. The broadband communication payload is responsible for realizing broadband communication functions (such as satellite Internet, data relay, etc.). In the embodiment of the present application, the broadband communication payload is used to execute another broadband communication payload test method provided in the embodiment of the present application. Its specific implementation method will also be described in detail in subsequent embodiments and will not be described here for the time being.

[0051] As another implementation, the satellite communication system provided in the embodiments of this application may also include a gateway. This gateway serves as the interface between the satellite and the terrestrial core network. It is responsible for connecting user-segment communication signals (such as mobile phone and shipboard terminal data) to the terrestrial network via the satellite payload, thus interconnecting satellite and terrestrial communications. In testing scenarios, the gateway can be used to verify the service-carrying capacity of the broadband communication payload.

[0052] As another embodiment, the satellite communication system provided in the embodiments of the present application may further include a ground support network. The ground support network provides basic support such as communication, power supply, data storage, and time and frequency synchronization for various devices in the ground segment, ensuring the coordinated operation between the tracking and control stations, control center, and signal gateways.

[0053] In existing technology, if each test item requires both remote control commands and telemetry information, the measurement and control link cannot handle the corresponding data transmission, and the integrated electronics cannot meet the resource consumption demands caused by the expansion of remote control and telemetry commands. Furthermore, after launch, if additional test items are needed, remote control and telemetry commands must be added, and the integrated electronics must be restructured and upgraded, increasing the operational risk of the satellite and the test and verification workload.

[0054] In view of this, an embodiment of the present application provides a broadband communication load testing method applied to a broadband communication load and a broadband communication load testing method applied to a control center, and defines a set of broadband communication load testing protocols in the above two methods.

[0055] The underlying communication link of the broadband communication payload testing protocol still uses a satellite measurement and control link to implement information exchange between the control center and the broadband communication payload. At this time, the integrated electronics on the measurement and control station and the satellite are unaware of the difference between information exchange based on this protocol and information exchange based on existing technologies. The information exchange implemented based on the broadband communication payload testing protocol includes payload test commands and payload information collection instructions, corresponding to a remote control command and a telemetry collection command of the measurement and control link. Among them, the payload test command is used to implement functions such as service control, data transmission, and protocol system parameter verification of the broadband communication payload, and the payload information collection instruction is used to collect the operating status of the broadband communication payload, software operating status, test command execution results, indicator statistics during the broadband communication process, and maintenance information.

[0056] Therefore, the embodiment of the present application can solve the problem of limited measurement and control link resources according to the principle of time division multiplexing, thereby achieving complete information collection. The technical solution in the embodiment of the present application will be described below in conjunction with the drawings in the embodiment of the present application.

[0057] Please refer to Figure 2 , Figure 2This is a flowchart of a method for testing a broadband communication payload applied to a broadband communication payload provided in an embodiment of the present application. This method can be executed by the broadband communication payload, or by a component of the broadband communication payload, such as a processor, chip, chip system, or circuit of the broadband communication payload. It can also be implemented by a logic module or software that can implement all or part of the broadband communication payload functions. The following description uses the method executed by the broadband communication payload as an example. The method may specifically include the following steps: S101: Receive a load test instruction, wherein the load test instruction includes at least one configuration field, and different configuration fields are used to instruct the broadband communication load to perform different test operations.

[0058] S102: Parsing the load test instruction based on the pre-stored broadband communication load test protocol to obtain a corresponding parsing result.

[0059] S103: Execute a test operation corresponding to the configuration field according to the parsing result.

[0060] Specifically, in S101 above, the payload test instruction includes at least one configuration field, with different configuration fields being used to instruct the broadband communication payload to perform different test operations. These test operations may include the broadband communication payload executing corresponding test actions and collecting corresponding test data. It should be noted that the embodiments of this application do not impose specific limitations on the number and size of these configuration fields, and those skilled in the art may make appropriate adjustments based on actual circumstances.

[0061] For example, the configuration field can be used to instruct the broadband communication payload to perform protocol system parameter verification; or, the configuration field can be used to instruct the broadband communication payload to collect satellite ton information; or, the configuration field can be used to instruct the broadband communication payload to execute corresponding services, etc.

[0062] The control center can generate the above-mentioned payload test instructions including the configuration fields according to the test requirements, and send the above-mentioned payload test instructions to the measurement and control station through the measurement and control link; the measurement and control station sends the received payload test instructions to the integrated electronics in the satellite, and the integrated electronics then forwards the payload test instructions to the broadband communication payload; in this way, the broadband communication payload receives the payload test instructions sent by the control center.

[0063] In the above S102, the underlying communication link of the broadband communication payload test protocol is based on the satellite measurement and control link, which is used for information exchange between the control center and the broadband communication payload. The measurement and control station and the onboard integrated electronics are not aware of the content of this protocol, thus avoiding large-scale transformation of the existing system and reducing system complexity and cost.

[0064] The broadband communication payload testing protocol can include two parts: test commands and test information collection. Test commands are used to control the broadband communication payload, such as adjusting the communication mode and configuring parameters; sending data to simulate data transmission in various business scenarios; and verifying protocol system parameters to ensure the normal operation of the broadband communication payload under different protocol standards. Test information collection is responsible for collecting the operating status of the broadband communication payload, including real-time information on hardware (such as temperature and voltage) and software (such as the operating status of each layer of the protocol stack); obtaining test command execution results to determine the success of the test and statistics of various indicators during the communication process (such as bit error rate and throughput); and collecting maintenance and testing information to provide data support for subsequent maintenance and troubleshooting.

[0065] As one embodiment, the broadband communication payload test protocol may be stored in the broadband communication payload by upgrading the corresponding software version in the broadband communication payload prior to executing the broadband communication payload test method provided in the embodiments of this application. As another embodiment, the broadband communication payload may already have stored the updated broadband communication payload test protocol prior to executing the broadband communication payload test method provided in the embodiments of this application.

[0066] The broadband communication payload can parse the payload test instructions based on the broadband communication payload test protocol to obtain the corresponding parsing results. Specifically, the configuration fields in the payload test instructions can be parsed as follows: for service control instructions, protocol layer parameters such as RRC and MAC are extracted and passed to the protocol processing unit via an internal interface; for test execution instructions, parameters such as the data transmission mode and duration are parsed to control the data generation unit.

[0067] In the above S103 , the broadband communication payload may perform a test operation corresponding to the configuration field according to the above parsing result, that is, perform a corresponding test action or collect corresponding test data.

[0068] In the above scheme, different test operations are integrated into a single payload test instruction through configuration fields. Simultaneously, the payload test instruction is parsed using a pre-stored broadband communication payload test protocol. This allows the broadband communication payload to perform functions such as service control, data transmission, and protocol system parameter verification. This overcomes the limitation of traditional instructions that can only perform a single function, enabling the broadband communication payload to perform diverse tests, thereby reducing the number of instructions, improving test efficiency, and minimizing the impact on the measurement and control station and integrated electronics. Therefore, the broadband communication payload testing method provided in the embodiments of the present application can solve the technical problem in the prior art where the measurement and control link cannot carry the corresponding data transmission.

[0069] Furthermore, based on the above embodiment, the load test instruction may further include an instruction header, and the instruction header may include an instruction code and an instruction length.

[0070] Specifically, the broadband communication payload on satellites used to have relatively simple functions, and the broadband communication payload could be controlled using some common remote control commands. However, the software complexity of the broadband communication payload based on the 3GPP NTN protocol system has increased significantly, and the configuration parameters and test verification items defined by each layer of the protocol have expanded dramatically compared to previous payloads. The embodiment of the present application adds a payload test instruction to complete the service control, data transmission and protocol system parameter verification of the broadband communication payload, minimizing the impact on the measurement and control station and integrated electronics. At the same time, the measurement and control link only serves as the underlying transmission channel. Subsequent upgrades to the broadband communication payload test protocol will not affect the measurement and control station and integrated electronics, reducing coupling.

[0071] The instruction code is used to indicate the type of load test instruction, and the instruction length is used to indicate the length of the load test instruction. The instruction header in the load test instruction can be parsed as follows: verifying the validity of the instruction code, comparing the instruction length with the actual received data length, and determining the instruction type based on the instruction code.

[0072] Please refer to Table 1, which shows a load test instruction. The instruction name of the instruction is load test instruction. The instruction description part includes an instruction header and a configuration field corresponding to the broadband communication load test protocol. The instruction header includes an instruction code with a length of 2 bytes and a value type of value, and an instruction length with a length of 2 bytes and a value type of value. The length of each configuration field is 1 byte and the value type is value.

[0073]

[0074] Table 1 A load test instruction As an implementation manner, the above S102 may specifically include the following steps: The first step is to determine the type of load test instruction based on the instruction code and compare the instruction length with the length of the load test instruction to see if they are consistent.

[0075] The second step is to determine the parameters corresponding to the test operation based on the configuration fields.

[0076] In the above scheme, the standardized design of the instruction header can simplify the parsing process, allowing broadband communication payloads to quickly identify instruction types, thereby reducing processing latency; the instruction length field reserves space for future expansion configuration fields, and new test functions can be added without modifying the basic instruction format, ensuring the system's compatibility with protocol evolution.

[0077] Further, based on the above embodiment, if the test operation includes collecting test information, then after the above S103, the broadband communication load testing method provided in the embodiment of the present application may further include the following steps: S201: After the test operation is completed, feedback information corresponding to the load test instruction is sent.

[0078] S202: Receive a load information collection instruction.

[0079] S203: Encapsulate the collected load test information into telemetry data and send the telemetry data.

[0080] Specifically, in S201 above, after the broadband communication payload completes the test operation corresponding to the payload test instruction, it may send feedback information corresponding to the payload test instruction to inform the control center that the test operation has been completed. The embodiments of this application do not specifically limit the specific implementation of the above feedback information, and those skilled in the art may make appropriate selections based on existing technologies.

[0081] If the test operation includes collecting test information, the control center can send a new instruction to the broadband communication payload to enable the broadband communication payload to send the collected test information to itself. In the embodiment of the present application, the new instruction can be implemented using a payload information collection instruction.

[0082] In the above S202, the load information collection instruction is the core instruction for interaction between the control center and the broadband communication load, and is used to trigger the broadband communication load to collect its own operating status and test data and feed the results back to the control center.

[0083] The control center can generate the above-mentioned payload information collection instructions according to the test requirements, and send the above-mentioned payload information collection instructions to the measurement and control station through the measurement and control link; the measurement and control station sends the received payload information collection instructions to the integrated electronics in the satellite, and the integrated electronics then forwards the payload information collection instructions to the broadband communication payload; in this way, the broadband communication payload receives the payload information collection instructions sent by the control center.

[0084] In the above S203, the broadband communication payload can encapsulate the collected load test information into telemetry data and forward the above telemetry data to the integrated electronics; the integrated electronics sends the received telemetry data to the measurement and control station, and the measurement and control station then sends the telemetry data to the control center through the measurement and control link; in this way, the control center receives the telemetry data sent by the broadband communication payload.

[0085] In this solution, feedback confirms the status of operational execution. Combining information collection with telemetry data transmission ensures the control center has real-time visibility into load status, improving fault location and repair efficiency. Furthermore, according to the principle of time-sharing multiplexing, information collection is triggered on demand after the test operation is executed, avoiding continuous bandwidth usage and alleviating the strain on measurement and control resources found in traditional methods.

[0086] Furthermore, based on the above embodiment, the telemetry data may include fixed telemetry items and custom telemetry items.

[0087] Specifically, in the current telemetry data collection, the broadband communication payload periodically feeds back fixed telemetry information. For a payload information collection instruction, the meaning of each byte of the telemetry data is fixed. If different telemetry data needs to be fed back, the corresponding payload information collection instruction needs to be defined. The broadband communication payload has a lot of internal states. According to the existing method, a large number of payload information collection instructions need to be defined. The integrated electronics is responsible for the management of all payloads on the satellite. The telemetry feedback resources of each payload are limited and cannot be met. In the embodiment of the present application, a custom area is allocated in the telemetry data. The meaning of this part is variable and can be controlled by the ground. The communication system telemetry data collection of the broadband communication payload is decoupled from the integrated electronics. The integrated electronics does not need to worry about the business implementation of the communication system, reducing the development workload and subsequent maintenance costs.

[0088] The above-mentioned fixed telemetry items need to be collected and fed back during each test data collection process. For example, fixed telemetry items may include satellite platform status (such as power supply voltage and temperature), payload hardware status (such as beam control unit current), etc.

[0089] These custom telemetry items are dynamically generated based on test requirements. For example, when testing the NTN protocol, protocol layer metrics such as RRC connection establishment success rate and PDCP layer latency are collected. The meaning of these custom telemetry items is dynamically configured by the control center through test commands, without modifying the payload hardware.

[0090] Please refer to Table 2, which shows telemetry data, which includes fixed telemetry items (telemetry item 1 to telemetry item N) and custom telemetry items, wherein each telemetry item includes a corresponding telemetry item name, telemetry item description, and telemetry item length.

[0091]

[0092] Table 2 A type of telemetry data In this solution, fixed telemetry items ensure basic status monitoring, while custom telemetry items allow for dynamic adjustment of collected data without modifying hardware or reconfiguring the instruction set, significantly reducing the cost of on-orbit satellite upgrades. Furthermore, the broadband communication payload's communication system telemetry data collection is decoupled from the integrated electronics, freeing the integrated electronics from the communication system's operational implementation, reducing development workload and subsequent maintenance costs.

[0093] Please refer to Figure 3 , Figure 3 This is a flowchart of a method for testing broadband communication load in a control center, provided in an embodiment of the present application. This method can be executed by the control center, or by components of the control center, such as a processor, chip, chip system, or circuit in the control center. It can also be implemented by a logic module or software that can implement all or part of the control center. The following description uses the method executed by the control center as an example. The method may specifically include the following steps: S301: Send a load test instruction, wherein the load test instruction includes at least one configuration field, and different configuration fields are used to instruct the broadband communication load to perform different test operations.

[0094] S302: Receive feedback information corresponding to the load test instruction, wherein the feedback information is used to indicate that the broadband communication load has completed the test operation.

[0095] In the above scheme, different test operations are integrated into a single payload test instruction through configuration fields. Simultaneously, the payload test instruction is parsed using a pre-stored broadband communication payload test protocol. This allows the broadband communication payload to perform functions such as service control, data transmission, and protocol system parameter verification. This overcomes the limitation of traditional instructions that can only perform a single function, enabling the broadband communication payload to perform diverse tests, thereby reducing the number of instructions, improving test efficiency, and minimizing the impact on the measurement and control station and integrated electronics. Therefore, the broadband communication payload testing method provided in the embodiments of the present application can solve the technical problem in the prior art where the measurement and control link cannot carry the corresponding data transmission.

[0096] Furthermore, based on the above embodiment, the load test instruction may further include an instruction header, and the instruction header may include an instruction code and an instruction length.

[0097] In the above scheme, the standardized design of the instruction header can simplify the parsing process, allowing broadband communication payloads to quickly identify instruction types, thereby reducing processing latency; the instruction length field reserves space for future expansion configuration fields, and new test functions can be added without modifying the basic instruction format, ensuring the system's compatibility with protocol evolution.

[0098] Further, based on the above embodiment, if the test operation includes collecting test information, then after the above S302, the broadband communication load testing method provided in the embodiment of the present application may further include the following steps: S401: Send a load information collection instruction.

[0099] S402: Receive telemetry data corresponding to the payload information collection instruction.

[0100] In this solution, feedback confirms the status of operational execution. Combining information collection with telemetry data transmission ensures the control center has real-time visibility into load status, improving fault location and repair efficiency. Furthermore, according to the principle of time-sharing multiplexing, information collection is triggered on demand after the test operation is executed, avoiding continuous bandwidth usage and alleviating the strain on measurement and control resources found in traditional methods.

[0101] Furthermore, based on the above embodiment, the telemetry data may also include fixed telemetry items and custom telemetry items.

[0102] In this solution, fixed telemetry items ensure basic status monitoring, while custom telemetry items allow for dynamic adjustment of collected data without modifying hardware or reconfiguring the instruction set, significantly reducing the cost of on-orbit satellite upgrades. Furthermore, the broadband communication payload's communication system telemetry data collection is decoupled from the integrated electronics, freeing the integrated electronics from the communication system's operational implementation, reducing development workload and subsequent maintenance costs.

[0103] Please refer to Figure 4. Figure 4 This is an interactive diagram of a broadband communication load testing method provided in an embodiment of the present application. The broadband communication load testing method may specifically include the following steps: S501: The control center sends a load test instruction, and the broadband communication payload receives the load test instruction.

[0104] S502: The broadband communication load parses the load test instruction based on a pre-stored broadband communication load test protocol to obtain a corresponding parsing result.

[0105] S503: The broadband communication payload performs a test operation corresponding to the configuration field according to the parsing result.

[0106] S504: After completing the test operation, the broadband communication payload sends feedback information corresponding to the payload test instruction.

[0107] S505: The control center sends a load information collection instruction, and the broadband communication load center receives the load information collection instruction.

[0108] S506: The broadband communication payload encapsulates the collected payload test information into telemetry data and sends the telemetry data, and the control center receives the telemetry data corresponding to the payload information collection instruction.

[0109] Therefore, the embodiment of the present application is transparent to the ground-based measurement and control system, measurement and control station, and integrated electronics on the satellite. No new equipment or modules are required. Subsequent test protocol upgrades only require reconstruction of the broadband communication payload without affecting other equipment or modules.

[0110] Furthermore, based on the above embodiment, before executing the two broadband communication load testing methods provided in the embodiments of the present application, the following steps may be performed: S601: The ground tracking and control station is successfully connected to the satellite.

[0111] S602: The ground control center sends a payload power-on instruction.

[0112] S603: The integrated electronics on the satellite receives the payload power-on instruction and powers on the payload.

[0113] S604: The payload is started and the CAN link is established with the integrated electronics.

[0117] In the above scheme, the standardized design of the instruction header can simplify the parsing process, allowing broadband communication payloads to quickly identify instruction types, thereby reducing processing latency; the instruction length field reserves space for future expansion configuration fields, and new test functions can be added without modifying the basic instruction format, ensuring the system's compatibility with protocol evolution.
