[0039] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0040] It should be noted that the terms "first," "second," and the like in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the numbers used in this manner are interchangeable where appropriate so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure as detailed in the appended claims.

[0041] The satellite base station commissioning method provided in the embodiment of the present application can be applied to Figure 1 The satellite-based base station commissioning and testing system shown in FIG. The satellite-based base station commissioning and testing system may include onboard components and ground components. The onboard components include an onboard integrated management system, an onboard measurement and control system, and a satellite base station 102. The satellite base station 102 includes an onboard communication payload baseband and an onboard communication payload antenna, where the antenna may be an array antenna. The ground components include a ground simulation terminal 104 and a ground station 106. The ground station 106 includes a ground station control and management system, a ground station measurement and control system, and a ground data analysis system. The ground simulation terminal can wirelessly communicate with the satellite-based base station via a physical channel. A measurement and control link can be established between the onboard measurement and control system and the ground station measurement and control system to transmit measurement and control command data and commissioning message data.

[0042] Among them, the onboard base station can be a base station deployed on the satellite, including a baseband and array antenna, and can also be called an onboard communication payload or satellite communication payload. The onboard integrated management system can be a memory and processor deployed on the satellite, implementing onboard integrated management functions. The onboard measurement and control system and the ground station measurement and control system can be measurement and control equipment deployed on the satellite and on the ground, respectively. The ground station control and management system can be a terminal or server deployed on the ground, implementing ground control and management functions. The ground data analysis system can be a terminal or server deployed on the ground, used for data storage, processing, and analysis. The ground simulation terminal can be, but is not limited to, a terminal, instrument, or server deployed on the ground, used to simulate ground terminal function debugging and conduct service protocol communication with the onboard base station.

[0043] In an exemplary embodiment, Figure 2 As shown, a satellite-borne base station commissioning method is provided. This embodiment uses the method applied to a ground station as an example for illustration, and includes the following steps:

[0044] Step S201: Send a first tuning parameter to the satellite base station, and send a second tuning parameter corresponding to the first tuning parameter to the ground simulation terminal; the satellite base station and the ground simulation terminal perform protocol communication according to the first tuning parameter and the second tuning parameter.

[0045] The first tuning parameter may be a parameter related to downlink transmission or uplink reception by the satellite base station, including but not limited to a downlink tuning instruction, an uplink tuning instruction, an array antenna parameter, a downlink tuning modulation parameter, an uplink tuning demodulation parameter, etc. The second tuning parameter may correspond to the first tuning parameter. When the first tuning parameter is a satellite base station transmission parameter, the second tuning parameter may be a ground simulation terminal reception parameter. When the first tuning parameter is a satellite base station reception parameter, the second tuning parameter may be a ground simulation terminal transmission parameter. For example, when the first tuning parameter is a modulation or coding parameter, the second tuning parameter may be a corresponding decoding or demodulation parameter. When the first tuning parameter is a decoding or demodulation parameter, the second tuning parameter may be a corresponding modulation or coding parameter.

[0046] The downlink tuning command may be a signaling instruction for tuning downlink transmission (air-to-ground) of a satellite-based base station. The uplink tuning command may be a signaling instruction for tuning uplink transmission (ground-to-air) of a satellite-based base station. Array antenna parameters include, but are not limited to, beam identification, beam angle pointing, effective time, signal duration, and signal strength.

[0047] Among them, the downlink commissioning modulation parameters can be the downlink control information (DCI) format, network temporary identifier (RNTI), time-frequency resources, modulation coding scheme (MCS), and system frame number (SFN), subframe (SF), signal duration, etc. used by the satellite base station to simulate loading and send physical downlink control channel (PDCCH) and physical downlink shared channel (PDSCH) data.

[0048] Among them, the uplink commissioning and demodulation parameters can be the physical uplink shared channel (PUSCH) related parameters required for the satellite base station to simulate uplink demodulation and decoding, including the uplink control information (UCI) format, RNTI, time-frequency resources, MCS level, beam direction, and the timestamp and duration of the effective data sent by the ground simulation terminal; it can also be the physical random access channel (PRACH) related parameters, including prefix scrambling code, message length, frequency resource location, sending time, sending interval, etc.

[0049] In the specific implementation, the ground station can send the first adjustment parameter to the satellite base station. After the satellite base station confirms that the first adjustment parameter is valid, the ground station sends the second adjustment parameter to the ground simulation terminal. Based on the pre-defined communication protocol, the satellite base station can communicate with the ground simulation terminal according to the first adjustment parameter, and the ground simulation terminal can communicate with the satellite base station according to the second adjustment parameter.

[0050] In actual applications, after the on-orbit satellite enters the communication field of view of the ground station measurement and control system and the ground simulation terminal, the ground station measurement and control system can establish a measurement and control link with the onboard measurement and control system. The ground station sends the first adjustment parameter to the onboard integrated management system through the measurement and control link, and the onboard integrated management system forwards the first adjustment parameter to the onboard base station. For downlink transmission of satellite communication payloads, the first adjustment parameter may include downlink adjustment instructions, array antenna parameters, and downlink adjustment modulation parameters. For uplink transmission of satellite communication payloads, the first adjustment parameter may include uplink adjustment instructions, array antenna parameters, and uplink adjustment demodulation parameters. If the onboard base station confirms that the first adjustment parameter is invalid, the adjustment process is terminated. Otherwise, if the onboard base station confirms that the first adjustment parameter is valid, it returns a confirmation of validity information to the ground station through the onboard integrated management system and the measurement and control link. Upon receiving the confirmation of validity information, the ground station sends the second adjustment parameter to the ground simulation terminal.

[0051] Step S202: receiving first commissioning data returned by the satellite-borne base station and second commissioning data returned by the ground simulation terminal.

[0052] Among them, the first tuning data may be an uplink test signal received by the satellite base station when the uplink transmission performance of the satellite base station is poor. The second tuning data may be a downlink test signal received by the ground simulation terminal when the downlink transmission performance of the satellite base station is poor. Among them, the uplink test signal may be a test signal for tuning the uplink transmission of the satellite base station. The downlink test signal may be a test signal for tuning the downlink transmission of the satellite base station. Poor transmission performance can be understood as decoding errors, bit error rate exceeding a certain threshold, or received signal quality (power, signal-to-noise ratio, etc.) below a certain threshold, etc., and this application does not impose any restrictions on this.

[0053] In a specific implementation, during the process of protocol communication between the satellite base station and the ground simulation terminal based on the first adjustment parameter and the second adjustment parameter, the satellite base station can collect the first adjustment data and return the first adjustment data to the ground station, and the ground simulation terminal can collect the second adjustment data and return the second adjustment data to the ground station.

[0054] In actual applications, for downlink transmission of the satellite base station, the satellite base station can send a downlink test signal according to the first tuning parameter (for example, a downlink sending parameter), and the ground simulation terminal receives the downlink test signal according to the second tuning parameter (for example, a downlink receiving parameter), and detects the downlink transmission performance of the satellite base station based on the received downlink test signal. If the transmission performance is poor, data collection is triggered, and the ground simulation terminal collects the received downlink test signal (air interface IQ data) as the second tuning data and returns it directly to the ground station, where the received downlink test signal can be understood as air interface in-phase / quadrature component (IQ) data.

[0055] For the uplink transmission of the satellite base station, the ground simulation terminal can send an uplink test signal according to the second tuning parameter (for example, the uplink sending parameter), and the satellite base station receives the uplink test signal according to the first tuning parameter (for example, the uplink receiving parameter), and detects the uplink transmission performance of the satellite base station based on the received uplink test signal. If the transmission performance is poor, data collection is triggered, and the satellite base station collects the received uplink test signal (air interface IQ data) as the first tuning data, and returns it to the ground station in sequence through the on-board integrated management system and the measurement and control link.

[0056] Step S203: Perform a first commissioning on the satellite-borne base station according to the first commissioning data and the second commissioning data.

[0057] The first commissioning may be an on-orbit commissioning of the satellite-borne base station for uplink and downlink communications.

[0058] In a specific implementation, the ground station may process and analyze the received first commissioning data and the second commissioning data, and perform the first commissioning on the satellite-borne base station according to the analysis result.

[0059] In actual applications, the ground station control and management system can send the first adjustment data returned by the satellite base station and the second adjustment data returned by the ground simulation terminal to the ground data analysis system. The ground data analysis system processes and analyzes the first adjustment data and the second adjustment data, and performs further on-orbit adjustment of the satellite base station based on the analysis results, including but not limited to locating the cause of the satellite base station failure, adjusting the satellite base station cell parameters, changing the antenna configuration, etc.

[0060] The above-mentioned satellite base station adjustment method sends a first adjustment parameter to the satellite base station, and sends a second adjustment parameter corresponding to the first adjustment parameter to the ground simulation terminal. The satellite base station and the ground simulation terminal perform protocol communication according to the first adjustment parameter and the second adjustment parameter, receive the first adjustment data returned by the satellite base station, and the second adjustment data returned by the ground simulation terminal, and perform a first adjustment on the satellite base station according to the first adjustment data and the second adjustment data; after the satellite enters orbit, the satellite base station and the ground simulation terminal can perform uplink and downlink protocol communication according to the adjustment parameters to obtain first adjustment data reflecting uplink transmission performance and second adjustment data reflecting downlink transmission performance. By analyzing the first adjustment data and the second adjustment data, the on-orbit adjustment of the satellite base station is realized.

[0061] In an exemplary embodiment, the above-mentioned step S201 may specifically include: sending a first tuning parameter to the satellite base station through a measurement and control link; the satellite base station switches to a tuning mode according to the first tuning parameter, and returns a first confirmation validity information of the tuning mode; upon receiving the first confirmation validity information, sending a second tuning parameter to the ground simulation terminal.

[0062] The commissioning mode may be a flag indicating on-orbit commissioning of uplink and downlink communications of the satellite-borne base station. The first validation confirmation information may be information indicating that the satellite-borne base station confirms that the first commissioning parameters are valid and switches to the commissioning mode.

[0063] In a specific implementation, the ground station can send the first adjustment parameter to the satellite base station through the measurement and control link. The satellite base station confirms whether the received first adjustment parameter is valid. If not, the adjustment is terminated. Otherwise, if valid, it switches to the adjustment mode and returns the first confirmation validity information to the ground station. When the ground station receives the first confirmation validity information, it can send the second adjustment parameter to the ground simulation terminal.

[0064] In actual applications, for downlink transmission of satellite base stations, the ground station control and management system can output first adjustment parameters including downlink adjustment instructions, array antenna parameters and downlink adjustment modulation parameters, and send them to the on-board integrated management system via the measurement and control link. The on-board integrated management system triggers the first adjustment parameters to the satellite base station in a timely manner. After the satellite base station (on-board communication payload baseband) confirms the validity of the first adjustment parameters, it switches to the downlink adjustment mode and feeds back the first confirmation validity information of the downlink adjustment mode to the on-board integrated management system. The on-board integrated management system feeds back the first confirmation validity information to the ground station control and management system through the measurement and control link. After receiving the first confirmation validity information fed back from the satellite, the ground station control and management system sends the second adjustment parameters (downlink reception related parameters) to the ground simulation terminal. The ground simulation terminal decodes the PDCCH and PDSCH channels according to the second adjustment parameters, and collects air interface IQ data when the conditional parameters (including but not limited to signal-to-noise ratio, bit error rate, air interface time) reach the preset threshold.

[0065] For uplink transmission of the satellite base station, the ground station control and management system can output first tuning parameters including uplink tuning instructions, array antenna parameters, and uplink tuning and demodulation parameters, and send them to the onboard integrated management system via the measurement and control link. The onboard integrated management system timely triggers the first tuning parameters to the satellite base station. After the satellite base station (onboard communication payload baseband) confirms the validity of the first tuning parameters, it switches to the uplink tuning mode and feeds back first confirmation validity information of the uplink tuning mode to the onboard integrated management system. The onboard integrated management system feeds back the first confirmation validity information to the ground station control and management system via the measurement and control link. After receiving the first confirmation validity information fed back from the satellite, the ground station control and management system sends second tuning parameters (uplink transmission-related parameters) to the ground simulation terminal. The ground simulation terminal performs modulation data transmission of the PUSCH channel or PRACH channel according to the second tuning parameters. The satellite base station decodes the PUSCH channel or PRACH channel and collects air interface IQ data when conditional parameters (including but not limited to signal-to-noise ratio, bit error rate, and air interface time) reach preset thresholds.

[0066] In this embodiment, the first tuning parameter is sent to the satellite base station through the measurement and control link. The satellite base station switches to the tuning mode according to the first tuning parameter and returns the first confirmation validity information of the tuning mode. Upon receiving the first confirmation validity information, the second tuning parameter is sent to the ground simulation terminal. The tuning mode can be switched to when the satellite base station is being tuned in orbit, thereby avoiding interference from other signals and increasing the accuracy of the in-orbit tuning.

[0067] In an exemplary embodiment, the tuning mode includes a downlink mode; the ground simulation terminal performs downlink signal processing on the downlink test signal sent by the satellite base station according to the second tuning parameter to obtain a downlink received signal. When the downlink received signal meets the first preset condition, the second tuning data is determined according to the received downlink test signal, and the second tuning data is sent to the ground station.

[0068] Among them, the downlink mode can be a mode for on-orbit debugging of the downlink transmission of the satellite-borne base station, which can also be called a downlink debugging mode. The downlink signal processing can be decoding, demodulation, cyclic redundancy check (CRC) and other processing at the downlink receiving end. The downlink received signal can be a signal formed by the received downlink test signal (air interface IQ data) after downlink signal processing. The first preset condition can be a decoding error, a downlink bit error rate exceeding a certain threshold, or the downlink received signal quality (power, signal-to-noise ratio, etc.) is lower than a certain threshold, etc. The second debugging data can be the demodulation result and demodulation process data, such as CRC, signal-to-noise ratio, time offset, frequency offset, IQ data and other contents, and this application does not impose any restrictions on this.

[0069] In a specific implementation, upon receiving a first tuning parameter including a downlink tuning instruction, array antenna parameters, and downlink tuning modulation parameters, the satellite-borne base station can switch to a downlink mode and return a first confirmation validity message of the downlink mode to the ground station. Upon receiving the first confirmation validity message, the ground station sends a second tuning parameter to the ground simulation terminal. The satellite-borne base station sends a downlink test signal according to the first tuning parameter, and the ground simulation terminal receives the downlink test signal according to the second tuning parameter, and performs downlink signal processing on the received downlink test signal to obtain a downlink received signal. If the downlink received signal is decoded incorrectly, the bit error rate exceeds a certain threshold, the power is lower than a certain threshold, or the signal-to-noise ratio is lower than a certain threshold, the ground simulation terminal collects the received downlink test signal and sends it to the ground station as the second tuning data.

[0070] In actual applications, after receiving downlink reception-related parameters from the ground station control and management system, the ground simulation terminal decodes the received downlink test signal. If the decoding CRC check is determined to be an error, the air interface IQ data collection instruction is triggered and the collected IQ data is saved. The SFN and SF at the time of IQ data collection can be strictly aligned to the pulse per second (PPS) signal, and the IQ data stored by the ground simulation terminal is no less than two time slots (SLOTs). The ground simulation terminal can package the collected IQ data and the parameters used for downlink demodulation and forward them to the ground data analysis system via the ground station control and management system.

[0071] In this embodiment, the ground simulation terminal performs downlink signal processing on the downlink test signal sent by the satellite base station according to the second adjustment parameter to obtain a downlink received signal. When the downlink received signal meets the first preset condition, the second adjustment data is determined according to the received downlink test signal, and the second adjustment data is sent to the ground station. This can detect insufficient downlink performance or working failure of the satellite base station, and reliably realize the downlink in-orbit adjustment of the satellite base station.

[0072] In an exemplary embodiment, the tuning mode includes an uplink mode; the satellite-borne base station performs uplink signal processing on the uplink test signal sent by the ground simulation terminal according to the first tuning parameter to obtain an uplink received signal. When the uplink received signal meets the second preset condition, the first tuning data is determined according to the received uplink test signal, and the first tuning data is sent to the ground station through the measurement and control link.

[0073] Among them, the uplink mode can be a mode for performing on-orbit commissioning of the uplink transmission of the satellite-borne base station, which can also be called an uplink commissioning mode. The uplink signal processing can be decoding, demodulation, CRC check and other processing at the uplink receiving end. The uplink received signal can be a signal formed by uplink signal processing of the received uplink test signal (air interface IQ data). The second preset condition can be a decoding error, an uplink bit error rate exceeding a certain threshold, or an uplink received signal quality (power, signal-to-noise ratio, etc.) below a certain threshold, etc., which is not limited in this application.

[0074] In a specific implementation, upon receiving a first tuning parameter including an uplink tuning instruction, array antenna parameters, and uplink tuning demodulation parameters, the satellite-borne base station can switch to an uplink mode and return a first confirmation validity message of the uplink mode to the ground station. Upon receiving the first confirmation validity message, the ground station sends a second tuning parameter to the ground simulation terminal. The ground simulation terminal sends an uplink test signal according to the second tuning parameter, and the satellite-borne base station receives the uplink test signal according to the first tuning parameter, and performs uplink signal processing on the received uplink test signal to obtain an uplink received signal. If the uplink received signal is decoded incorrectly, the bit error rate exceeds a certain threshold, the power is lower than a certain threshold, or the signal-to-noise ratio is lower than a certain threshold, the satellite-borne base station collects the received uplink test signal as the first tuning data and sends it to the ground station via a measurement and control link.

[0075] In practical applications, after receiving the uplink reception-related parameters from the ground station control and management system via the measurement and control link, the satellite base station decodes the received uplink test signal within the signal's valid duration. If the decoding is correct, the satellite base station packages the measured parameters, such as the signal-to-noise ratio (SNR), received signal strength indicator (RSSI), SFN, and SF, and transmits them to the satellite integrated management system. The system then transmits them back to the ground station control and management system via the measurement and control link. Otherwise, if the decoding CRC error is detected, an air interface IQ data collection instruction is triggered, and the collected IQ data is stored. The SFN and SF at the time of IQ data collection must be strictly aligned to the pulse-per-second signal, and the duration of the IQ data stored by the satellite base station must be no less than two time slots. The satellite base station can package the collected IQ data and the parameters used for uplink demodulation and transmit them to the satellite integrated management system. The system then transmits the demodulation parameters and IQ data back to the ground station control and management system via the measurement and control link.

[0076] In this embodiment, the satellite-borne base station performs uplink signal processing on the uplink test signal sent by the ground simulation terminal according to the first adjustment parameter to obtain an uplink received signal. When the uplink received signal meets the second preset condition, the first adjustment data is determined according to the received uplink test signal, and the first adjustment data is sent to the ground station through the measurement and control link. This can detect insufficient uplink performance or working failure of the satellite-borne base station, and reliably realize the in-orbit uplink adjustment of the satellite-borne base station.

[0077] The above embodiment provides an on-orbit debugging method for uplink and downlink of a satellite-borne base station. In practical applications, it is also necessary to perform on-orbit debugging of the satellite-borne base station for the terminal access process. In an exemplary embodiment, Figure 3 As shown, a satellite-borne base station commissioning method for a terminal access process is provided, which specifically includes the following steps:

[0078] Step S301: Send a third tuning parameter to the satellite base station via a measurement and control link; the satellite base station switches to a quasi-service mode according to the third tuning parameter and returns a second confirmation validation message of the quasi-service mode;

[0079] Step S302: Upon receiving the second confirmation validation information, a fourth tuning parameter corresponding to the third tuning parameter is sent to the ground simulation terminal; the satellite base station and the ground simulation terminal perform a terminal access process according to the third tuning parameter and the fourth tuning parameter;

[0080] Step S303, receiving the first process data returned by the satellite base station and the second process data returned by the ground simulation terminal;

[0081] Step S304: Perform a second commissioning on the satellite-borne base station according to the first process data and the second process data.

[0082] Among them, the third tuning parameter can be a parameter for the satellite base station to perform the terminal access process, including but not limited to the terminal access process tuning instruction, array antenna parameters, parameters such as the beam direction required for the satellite base station to perform quasi-service mode, the timestamp and signal duration when the ground simulation terminal starts sending service data. The quasi-service mode can be a mark indicating that the satellite base station is to perform on-orbit tuning for the terminal access process, and can also be called a quasi-service tuning mode. The fourth tuning parameter corresponds to the third tuning parameter and can be a parameter for the ground simulation terminal to perform the terminal access process. The second confirmation validity information can be information that the satellite base station confirms that the third tuning parameter is valid and the base station status is normal, and switches to quasi-service mode. The first process data can be data recorded by the satellite base station that reflects the characteristics of the terminal access process. The second process data can be data recorded by the ground simulation terminal that reflects the characteristics of the terminal access process. The second tuning can be an on-orbit tuning of the satellite base station for the terminal access process.

[0083] In a specific implementation, the ground station can send the third adjustment parameter to the satellite base station through the measurement and control link. If the satellite base station confirms that the third adjustment parameter is invalid, the adjustment process is terminated. Otherwise, if the satellite base station confirms that the third adjustment parameter is valid and the base station status is normal, it switches to the quasi-business mode and returns the second confirmation validity information of the quasi-business mode to the ground station. When the ground station receives the second confirmation validity information, it can send the fourth adjustment parameter to the ground simulation terminal. The ground simulation terminal executes the terminal access process according to the received fourth adjustment parameter, and the satellite base station interacts with the ground simulation terminal according to the third adjustment parameter. During the terminal access process, the satellite base station can collect the first process data and return it to the ground station through the measurement and control link. The ground simulation terminal can collect the second process data and send it directly to the ground station. The ground station can perform data processing and analysis based on the received first process data and second process data, and perform a second adjustment on the satellite base station based on the analysis results.

[0084] In actual applications, after the in-orbit satellite enters the communication field of view of the ground station measurement and control system and the ground simulation terminal, the ground station measurement and control system can establish a measurement and control link with the onboard measurement and control system. The ground station control and management system outputs third measurement parameters including terminal access process measurement instructions, array antenna parameters, beam direction, timestamp, signal duration, etc., and sends them to the onboard integrated management system via the measurement and control link. The onboard integrated management system triggers the third measurement parameters to the onboard base station in a timely manner. The onboard base station (onboard communication payload baseband) confirms the validity of the third measurement parameters. After the base station status is normal, it feedbacks the second confirmation validity information of the quasi-business mode to the onboard integrated management system. The onboard integrated management system feedbacks the second confirmation validity information to the ground station control and management system via the measurement and control link. After receiving the second confirmation validity information fed back from the satellite, the ground station control and management system sends the fourth measurement parameters to the ground simulation terminal to carry out the terminal access process.

[0085] During the access process, the satellite-borne base station records first process data reflecting the characteristics of the access process, which may specifically include:

[0086] Demodulate the MSG1 time SFN, SLOT, received power RSSI, SNR, timing advance (TA), and preamble ID;

[0087] The SFN, SLOT, and TA of the time when MSG2 is sent, the SFN and SLOT of the expected reception of MSG3, and the number and location of resource blocks (RBs) allocated to MSG3;

[0088] Demodulate SFN, SLOT, TA, received power, and SNR at the time of MSG3 demodulation;

[0089] SFN and SLOT of the time when MSG4 is sent, and SFN and SLOT of the received confirmation (ACK);

[0090] SFN, SLOT, received power, SNR, and number of decoded Scheduling Requests (SRs) at the time of demodulation of MSG5;

[0091] The time SFN, SLOT, stream parameters, and data of sending DCI and UCI.

[0092] After the signal duration ends and the adjustment is completed, the satellite base station will package the collected first process data and send it to the onboard integrated management system, switching the satellite base station from the quasi-business mode back to the original business mode. The onboard integrated management system will return the first process data to the ground station control and management system through the measurement and control link, and the ground station control and management system will send the collected first process data to the ground data analysis system.

[0093] At the same time, after receiving the second confirmation validity information fed back from the satellite, the ground station control and management system sends the fourth commissioning parameters to the ground simulation terminal. The ground simulation terminal executes the terminal access process within the signal duration and records the second process data reflecting the characteristics of the access process, which may specifically include:

[0094] Decode the SFN, SLOT, received power, and SNR of the synchronization signal block (SSB) and system information block (SIB) SIB1 and SIB19;

[0095] SFN, SLOT, transmit power RSSI, and PREAMBLE ID at the time MSG1 is sent;

[0096] Decode the SFN and SLOT of MSG2, send the SFN and SLOT of MSG3, and the number and location of the allocated resource RBs of MSG3;

[0097] SFN, SLOT, transmit power, and cumulative number of times when MSG3 is sent;

[0098] Decode the SFN, SLOT, and CRC results of MSG4 at the moment of decoding;

[0099] SFN and SLOT of sending ACK;

[0100] SFN, SLOT, transmit power, and SNR at the time MSG5 is sent;

[0101] SFN and SLOT of the sending SR;

[0102] Decode the SFN, SLOT, and bitrate parameters of UCI.

[0103] After the signal duration ends and the commissioning is completed, the ground simulation terminal packages the collected second process data and sends it to the ground station control and management system. The ground station control and management system sends the second process data collected by the ground simulation terminal to the ground data analysis system.

[0104] The ground data analysis system can integrate the process data (first process data and second process data) within the duration of the same signal at both ends of the satellite and the ground, conduct offline analysis on them, and perform on-orbit commissioning of the satellite base station based on the analysis results, including but not limited to locating the cause of the satellite base station failure, adjusting the satellite base station cell parameters, changing the antenna configuration, and determining whether the first commissioning is required.

[0105] It should be noted that the above MSG1 to MSG5 are key signaling interaction processes in the terminal access process. MSG1 represents a random access request, MSG2 represents a random access response, MSG3 represents a radio resource control (RRC) connection request, MSG4 represents contention resolution, and MSG5 represents RRC establishment completion.

[0106] In this embodiment, a third adjustment parameter is sent to the satellite base station through the measurement and control link. The satellite base station switches to the quasi-business mode according to the third adjustment parameter and returns the second confirmation validity information of the quasi-business mode. Upon receiving the second confirmation validity information, a fourth adjustment parameter corresponding to the third adjustment parameter is sent to the ground simulation terminal. The satellite base station and the ground simulation terminal perform the terminal access process according to the third adjustment parameter and the fourth adjustment parameter, receive the first process data returned by the satellite base station and the second process data returned by the ground simulation terminal, and perform a second adjustment on the satellite base station according to the first process data and the second process data. In-orbit adjustment can be performed for insufficient performance or working failure of the satellite base station during the terminal access process, thereby meeting various needs of in-orbit adjustment of the satellite base station.

[0107] In an exemplary embodiment, Figure 4 As shown, a satellite base station commissioning method is provided. This embodiment uses the method applied to a satellite base station as an example for illustration, and includes the following steps:

[0108] Step S401: receiving a first tuning parameter sent by a ground station; the ground station also sends a second tuning parameter corresponding to the first tuning parameter to a ground simulation terminal;

[0109] Step S402: perform protocol communication with the ground simulation terminal according to the first adjustment parameter and return the first adjustment data; the ground simulation terminal performs protocol communication with the satellite base station according to the second adjustment parameter and returns the second adjustment data. The ground station performs the first adjustment on the satellite base station according to the first adjustment data and the second adjustment data.

[0110] In the specific implementation, the ground station can send the first adjustment parameter to the satellite base station through the measurement and control link, and directly send the second adjustment parameter to the ground simulation terminal. Based on the pre-defined communication protocol, the satellite base station communicates uplink and downlink with the ground simulation terminal according to the first adjustment parameter, and the ground simulation terminal communicates uplink and downlink with the satellite base station according to the second adjustment parameter. When poor transmission performance is detected, the satellite base station collects the first adjustment data and returns it to the ground station through the measurement and control link. The ground simulation terminal collects the second adjustment data and returns it directly to the ground station. The ground station performs the first adjustment on the satellite base station based on the first adjustment data and the second adjustment data.

[0111] Since the specific processing process of the satellite-borne base station has been described in detail in the above embodiments, it will not be repeated here.

[0112] In this embodiment, by receiving the first adjustment parameter sent by the ground station, the ground station also sends the second adjustment parameter corresponding to the first adjustment parameter to the ground simulation terminal, performs protocol communication with the ground simulation terminal according to the first adjustment parameter, and returns the first adjustment data. The ground simulation terminal performs protocol communication with the satellite base station according to the second adjustment parameter, and returns the second adjustment data. The ground station performs a first adjustment on the satellite base station according to the first adjustment data and the second adjustment data. After the satellite enters orbit, the satellite base station and the ground simulation terminal can perform uplink and downlink protocol communication according to the adjustment parameters to obtain the first adjustment data reflecting the uplink transmission performance and the second adjustment data reflecting the downlink transmission performance. By analyzing the first adjustment data and the second adjustment data, the on-orbit adjustment of the satellite base station is realized.

[0113] In an exemplary embodiment, after the above step S401, it may further include: switching to the tuning mode according to the first tuning parameter; returning the first confirmation validity information of the tuning mode; and the ground station sending the second tuning parameter to the ground simulation terminal when receiving the first confirmation validity information.

[0114] In a specific implementation, the ground station can send the first adjustment parameter to the satellite base station through the measurement and control link. The satellite base station confirms whether the received first adjustment parameter is valid. If not, the adjustment is terminated. Otherwise, if valid, it switches to the adjustment mode and returns the first confirmation validity information to the ground station. When the ground station receives the first confirmation validity information, it can send the second adjustment parameter to the ground simulation terminal.

[0115] In this embodiment, by switching to the tuning mode according to the first tuning parameter and returning the first confirmation validity information of the tuning mode, the ground station sends the second tuning parameter to the ground simulation terminal when receiving the first confirmation validity information. It can switch to the tuning mode when performing on-orbit tuning of the satellite-borne base station, avoiding interference from other signals and increasing the accuracy of on-orbit tuning.

[0116] In an exemplary embodiment, the above-mentioned step S402 may specifically include: performing uplink signal processing on the uplink test signal sent by the ground simulation terminal according to the first adjustment parameter to obtain an uplink received signal; when the uplink received signal meets the second preset condition, determining the first adjustment data based on the received uplink test signal; and sending the first adjustment data to the ground station through the measurement and control link.

[0117] In a specific implementation, upon receiving a first tuning parameter including an uplink tuning instruction, array antenna parameters, and uplink tuning demodulation parameters, the satellite-borne base station can switch to an uplink mode and return a first confirmation validity message of the uplink mode to the ground station. Upon receiving the first confirmation validity message, the ground station sends a second tuning parameter to the ground simulation terminal. The ground simulation terminal sends an uplink test signal according to the second tuning parameter, and the satellite-borne base station receives the uplink test signal according to the first tuning parameter, and performs uplink signal processing on the received uplink test signal to obtain an uplink received signal. If the uplink received signal is decoded incorrectly, the bit error rate exceeds a certain threshold, the power is lower than a certain threshold, or the signal-to-noise ratio is lower than a certain threshold, the satellite-borne base station collects the received uplink test signal as the first tuning data and sends it to the ground station via a measurement and control link.

[0118] In this embodiment, uplink signal processing is performed on the uplink test signal sent by the ground simulation terminal according to the first adjustment parameter to obtain an uplink received signal. When the uplink received signal meets the second preset condition, the first adjustment data is determined according to the received uplink test signal, and the first adjustment data is sent to the ground station through the measurement and control link. This can detect insufficient uplink performance or working failure of the satellite-borne base station, and reliably realize the in-orbit uplink adjustment of the satellite-borne base station.

[0119] In an exemplary embodiment, Figure 5 As shown, a satellite-borne base station commissioning method is provided. This embodiment uses the method applied to a ground simulation terminal as an example for illustration, and includes the following steps:

[0120] Step S501: receiving a second tuning parameter sent by a ground station; the ground station also sends a first tuning parameter corresponding to the second tuning parameter to the satellite-borne base station;

[0121] Step S502: Perform protocol communication with the satellite base station according to the second tuning parameters and return the second tuning data; the satellite base station performs protocol communication with the ground simulation terminal according to the first tuning parameters and returns the first tuning data. The ground station performs the first tuning on the satellite base station according to the first tuning data and the second tuning data.

[0122] In the specific implementation, the ground station can send the first adjustment parameter to the satellite base station through the measurement and control link, and directly send the second adjustment parameter to the ground simulation terminal. Based on the pre-defined communication protocol, the satellite base station communicates uplink and downlink with the ground simulation terminal according to the first adjustment parameter, and the ground simulation terminal communicates uplink and downlink with the satellite base station according to the second adjustment parameter. When poor transmission performance is detected, the satellite base station collects the first adjustment data and returns it to the ground station through the measurement and control link. The ground simulation terminal collects the second adjustment data and returns it directly to the ground station. The ground station performs the first adjustment on the satellite base station based on the first adjustment data and the second adjustment data.

[0123] Since the specific processing process of the ground simulation terminal has been described in detail in the above embodiments, it will not be repeated here.

[0124] In this embodiment, by receiving the second adjustment parameter sent by the ground station, the ground station also sends the first adjustment parameter corresponding to the second adjustment parameter to the satellite base station, performs protocol communication with the satellite base station according to the second adjustment parameter, and returns the second adjustment data. The satellite base station performs protocol communication with the ground simulation terminal according to the first adjustment parameter and returns the first adjustment data. The ground station performs a first adjustment on the satellite base station according to the first adjustment data and the second adjustment data. After the satellite enters orbit, the satellite base station and the ground simulation terminal can perform uplink and downlink protocol communication according to the adjustment parameters to obtain the first adjustment data reflecting the uplink transmission performance and the second adjustment data reflecting the downlink transmission performance. By analyzing the first adjustment data and the second adjustment data, the on-orbit adjustment of the satellite base station is realized.

[0125] In an exemplary embodiment, the above-mentioned step S502 may specifically include: performing downlink signal processing on the downlink test signal sent by the satellite base station according to the second tuning parameter to obtain a downlink received signal; when the downlink received signal meets the first preset condition, determining the second tuning data based on the received downlink test signal; and sending the second tuning data to the ground station.

[0126] In a specific implementation, upon receiving a first tuning parameter including a downlink tuning instruction, array antenna parameters, and downlink tuning modulation parameters, the satellite-borne base station can switch to a downlink mode and return a first confirmation validity message of the downlink mode to the ground station. Upon receiving the first confirmation validity message, the ground station sends a second tuning parameter to the ground simulation terminal. The satellite-borne base station sends a downlink test signal according to the first tuning parameter, and the ground simulation terminal receives the downlink test signal according to the second tuning parameter, and performs downlink signal processing on the received downlink test signal to obtain a downlink received signal. If the downlink received signal is decoded incorrectly, the bit error rate exceeds a certain threshold, the power is lower than a certain threshold, or the signal-to-noise ratio is lower than a certain threshold, the ground simulation terminal collects the received downlink test signal and sends it to the ground station as the second tuning data.

[0127] In this embodiment, downlink signal processing is performed on the downlink test signal sent by the satellite base station according to the second adjustment parameter to obtain a downlink received signal. When the downlink received signal meets the first preset condition, the second adjustment data is determined according to the received downlink test signal, and the second adjustment data is sent to the ground station. This can detect insufficient downlink performance or working failure of the satellite base station, and reliably realize the downlink in-orbit adjustment of the satellite base station.

[0128] In an exemplary embodiment, Figure 1 As shown, a satellite-borne base station commissioning system is provided, comprising:

[0129] The ground station 106 is configured to send the first tuning parameter to the satellite base station 102 and send the second tuning parameter corresponding to the first tuning parameter to the ground simulation terminal 104;

[0130] The satellite-borne base station 102 is configured to perform protocol communication with the ground simulation terminal 104 according to the first commissioning parameter and return first commissioning data;

[0131] The ground simulation terminal 104 is configured to perform protocol communication with the satellite base station 102 according to the second commissioning parameters and return the second commissioning data;

[0132] The ground station 106 is further configured to perform a first commissioning on the satellite-borne base station 102 according to the first commissioning data and the second commissioning data.

[0133] In the specific implementation, the ground station can send the first adjustment parameter to the satellite base station through the measurement and control link, and directly send the second adjustment parameter to the ground simulation terminal. Based on the pre-defined communication protocol, the satellite base station communicates uplink and downlink with the ground simulation terminal according to the first adjustment parameter, and the ground simulation terminal communicates uplink and downlink with the satellite base station according to the second adjustment parameter. When poor transmission performance is detected, the satellite base station collects the first adjustment data and returns it to the ground station through the measurement and control link. The ground simulation terminal collects the second adjustment data and returns it directly to the ground station. The ground station performs the first adjustment on the satellite base station based on the first adjustment data and the second adjustment data.

[0134] Since the specific processing procedures of the ground station, the satellite-borne base station and the ground simulation terminal have been described in detail in the above embodiments, they will not be repeated here.

[0135] In this embodiment, a first tuning parameter is sent to the satellite base station through the ground station, and a second tuning parameter corresponding to the first tuning parameter is sent to the ground simulation terminal. The satellite base station performs protocol communication with the ground simulation terminal according to the first tuning parameter and returns the first tuning data. The ground simulation terminal performs protocol communication with the satellite base station according to the second tuning parameter and returns the second tuning data. The ground station performs a first tuning on the satellite base station according to the first tuning data and the second tuning data. After the satellite enters orbit, the satellite base station and the ground simulation terminal can perform uplink and downlink protocol communication according to the tuning parameters to obtain first tuning data reflecting the uplink transmission performance and second tuning data reflecting the downlink transmission performance. By analyzing the first tuning data and the second tuning data, on-orbit tuning of the satellite base station can be realized.

[0136] In order to facilitate those skilled in the art to have a deeper understanding of the embodiments of the present application, a specific example will be used for illustration below.

[0137] For renewable low-orbit satellite constellation communication systems, the normal communication mode is for user terminals to communicate with satellite payloads, known as the user link. After the satellite demodulates the user signal, it communicates with a ground gateway, known as the feeder link. Typically, satellite payloads launched into orbit for the first time undergo in-orbit startup and commissioning to ensure proper operation and maximum efficiency.

[0138] On-orbit commissioning needs to verify whether the satellite base station is working as expected, including aspects such as signal quality, frequency response, power output, and demodulation capability, to ensure that the functions of the satellite base station meet the requirements for normal communication with the ground. If it is found that the satellite base station has insufficient performance or malfunctions during operation after entering orbit, it is expected that remote adjustment, troubleshooting, and repair can be achieved through a set of commissioning processes. By setting the commissioning mode, this application can adjust the parameters of the satellite base station, change the antenna configuration, and configure certain special scenarios to capture real-time data and transmit it back to the ground for analysis, and even repair potential problems through software upgrades.

[0139] Since low-orbit satellite communication systems are generally equipped with measurement and control systems, which can be used to transmit working data or send instructions to onboard base stations, the ground station control and management system can use these data to set the required working status, command the onboard base station to send summary and transmit its business status, or capture data and send it back to the ground station control and management system for ground offline data simulation to troubleshoot the cause of the problem.

[0140] Based on this, the present application proposes a satellite-borne base station debugging method suitable for low-orbit satellite communication systems, including: controlling the satellite-borne base station through a measurement and control link to send specific modulated signal data (downlink test signal) in the downlink direction, similar to the ground base station pile driving test mode, for the ground terminal or signal instrument to analyze the parameter indicators of each downlink channel. In the uplink direction, the ground simulation terminal or signal gateway executes the antenna angle and sends a modulated signal (uplink test signal) of a specific parameter source at a specific time. At the same time, through the measurement and control link, the baseband uplink of the onboard communication payload is controlled to demodulate at a specific time to obtain decoding performance indicators or capture signal air interface data, and then transmit it back through the measurement and control link to ensure that the collected data can eventually be obtained by the ground; the data collected by the satellite base station is strictly aligned to the PPS second pulse signal, and the data file is timestamped, specifically to SFN and SF, and the whole second is transmitted with the measurement and control to ensure that the absolute time corresponding to the collected data is traceable. After being transmitted back to the ground, it is convenient for the network management or control center to analyze.

[0141] The downlink direction refers to the direction in which the satellite base station (on-board communication payload baseband) sends signals to the ground simulation terminal through the downlink channel, and the uplink direction refers to the direction in which the ground simulation terminal sends signals to the satellite base station (on-board communication payload baseband) through the uplink channel. Figure 6 shown.

[0142] Among them, the satellite-borne base station of the low-orbit satellite communication system can transmit and receive data with ground terminals and signal gateways (power feeders) in accordance with the 5G New Radio (NR) technology. It also includes the NTN system protocol process data transmission based on the 5G New Radio, which is an improvement in air interface technology to adapt to low-orbit satellite communication scenarios.

[0143] The above-mentioned satellite base station commissioning method can effectively guide the ground or satellite base station to perform specific channel modulation signal transmission or detection analysis, cooperate with the satellite base station or the ground to capture and analyze data and feedback the results, so as to timely and effectively analyze the on-orbit test results and locate the reasons for poor communication quality or failure of the satellite base station.

[0144] In one embodiment, Figure 7 As shown in the figure, a satellite base station commissioning method is provided. This method can identify abnormal link nodes through a complete set of test processes, facilitating air interface troubleshooting. Figure 1 The on-orbit related system modules for executing this method include: on-board communication payload baseband system, on-board integrated management system, on-board measurement and control system, on-board communication payload array antenna, etc. The ground-related auxiliary modules required for executing this method include: ground station control and management system, ground station measurement and control system, ground simulation terminal system, ground data analysis system, etc.

[0145] The above-mentioned satellite-borne base station commissioning method applicable to the low-orbit satellite communication system may specifically include:

[0146] Step S601, onboard base station operating mode configuration and feedback: When commissioning the onboard base station, the ground station control and management system first outputs a payload commissioning command to each component on the satellite via the measurement and control link. If the onboard base station operating mode is successfully switched to the payload commissioning mode, a confirmation message (first confirmation message) is sent to the ground station via the onboard measurement and control system.

[0147] Step S602, onboard base station parameter configuration: the ground station control and management system injects the tuning parameters (first tuning parameters) to the onboard integrated management system via the measurement and control link, and the onboard integrated management system forwards the tuning parameters to the onboard communication payload baseband;

[0148] Step S603, the satellite base station is commissioned and operated: the satellite communication payload baseband performs the commissioning function according to the commissioning parameters;

[0149] Step S604, ground simulation terminal parameter configuration: the ground station control and management system synchronously transmits the peer terminal (spaceborne base station) commissioning parameters (second commissioning parameters) to the ground simulation terminal;

[0150] Step S605, the ground simulation terminal is debugged and operated: the ground simulation terminal performs a debugging function according to the debugging parameters (the first debugging parameter and the second debugging parameter);

[0151] Step S606: The satellite-borne base station test data is collected and sent down: the satellite communication payload baseband transmits the test results and captured IQ data (first commissioning data) to the ground station control and management system through the satellite measurement and control system;

[0152] Step S607, ground simulation terminal test data collection: the ground simulation terminal transmits the execution result (second debugging data) of the corresponding debugging parameter to the ground station control and management system;

[0153] Step S608, the satellite base station switches to the original operating mode: after the commissioning is completed, the satellite base station switches back to the original operating mode;

[0154] Step S609, test result analysis: the ground station control and management system sends the collected data to the ground data analysis system through the network, and generates test analysis results through data preprocessing, analytical simulation, indicator analysis and statistics.

[0155] In order to better illustrate this debugging method, the following embodiments list the detailed process of debugging a certain channel air interface transmission data in the downlink and uplink directions. Other different parameter combinations and data transmission and reception of wireless channels, or debugging of feeder links and user links are still applicable to the method described in this application.

[0156] In one embodiment, reference Figure 8 The baseband downlink signal commissioning process is explained by taking the satellite base station as an example: it sends SIB broadcast information on the PDSCH channel at all times in the downlink below the user link, and points it to the ground terminal. At the same time, the ground simulated terminal performs real-time demodulation. The specific steps and characteristics are as follows:

[0157] Step S701: After the on-orbit satellite enters the communication field of view of the ground station measurement and control system and the ground simulation terminal, the ground station measurement and control system establishes a link with the onboard measurement and control system;

[0158] In step S702, the ground station control and management system outputs first tuning parameters to the onboard integrated management system via the measurement and control link. The first tuning parameters include:

[0159] Downlink commissioning command: The operating mode of the satellite base station is configured as user downlink commissioning mode (downlink commissioning mode);

[0160] Array antenna parameters: The downlink transmit array antenna of the onboard communication payload needs to adjust the antenna pointing parameters of the ground simulation terminal, including beam ID, angle pointing, effective time, and signal duration T;

[0161] Downlink modulation parameter test: The baseband simulation of the satellite communication payload is used to load the DCI format, RNTI, time-frequency resources, MCS and other parameters used to send downlink signal PDCCH and PDSCH data, as well as the data transmission time SFN, SF and signal duration T;

[0162] The onboard integrated management system timely triggers the first adjustment parameter to the onboard base station. The onboard communication payload baseband confirms the validity of the first adjustment parameter and switches to the downlink adjustment mode, and feeds back confirmation and effectiveness information of the downlink adjustment mode (first confirmation and effectiveness information) to the onboard integrated management system.

[0163] The onboard integrated management system feeds back the confirmation information of the downlink adjustment mode to the ground station control and management system through the onboard measurement and control system;

[0164] After receiving the confirmation information from the satellite, the ground station control and management system sends the second commissioning parameters to the ground simulation terminal. The ground simulation terminal performs broadcast message SIB, PDCCH and PDSCH channel decoding and collects air interface IQ data. The second commissioning parameters are consistent with the first commissioning parameters on the satellite base station side.

[0165] Step S703: After receiving the downlink test signal sent by the satellite base station, the ground simulation terminal decodes it and collects and sends the decoding result to the ground data analysis system. After the ground simulation terminal determines that the decoding CRC check error occurs and triggers the IQ data collection instruction, it collects and saves the IQ data. The SFN and SF at the time of data collection can be strictly aligned with the PPS pulse second signal. The IQ data stored in the ground simulation terminal has a storage duration of not less than 2 time slots. The collected data and corresponding demodulation parameters are packaged and forwarded to the ground data analysis system via the ground station control and management system. The satellite base station switches back to the original service mode.

[0166] In step S704, the ground data analysis system performs offline preprocessing, simulation analysis, analysis and statistics on the collected data and corresponding demodulation parameters to generate test analysis results.

[0167] In one embodiment, reference Figure 9 The baseband uplink signal commissioning process is explained using a ground-based simulated terminal that sends modulated signals on the shared channel PUSCH at all times in the user link uplink. The specific steps and characteristics are as follows:

[0168] Step S801: After the on-orbit satellite enters the communication field of view of the ground station measurement and control system and the ground simulation terminal, the ground station measurement and control system establishes a link with the onboard measurement and control system;

[0169] In step S802, the ground station control and management system outputs first tuning parameters to the onboard integrated management system via the measurement and control link. The first tuning parameters include:

[0170] Uplink commissioning command: The operating mode of the satellite base station is configured as user uplink commissioning mode (uplink commissioning mode);

[0171] Array antenna parameters: parameters required to adjust the antenna pointing direction of the uplink receiving array antenna of the onboard communication payload to the ground simulation terminal, including beam ID, angle pointing, effective time, and signal duration T;

[0172] Uplink commissioning and demodulation parameters: PUSCH-related parameters required for uplink demodulation of the onboard communication payload baseband simulation, including parameters such as UCI format, RNTI, time-frequency resources, MCS level, beam direction, as well as the timestamp and signal duration T of the effective data sent by the ground simulation terminal;

[0173] The onboard integrated management system timely triggers the first adjustment parameter to the onboard base station. The onboard communication payload baseband confirms the validity of the first adjustment parameter and switches to the uplink adjustment mode, and feeds back confirmation information of the uplink adjustment mode to the onboard integrated management system.

[0174] The onboard integrated management system feeds back the confirmation and effectiveness information (first confirmation and effectiveness information) of the uplink adjustment mode to the ground station control and management system through the onboard measurement and control system;

[0175] After receiving the confirmation information from the satellite, the ground station control and management system sends the second tuning parameters to the ground simulation terminal to send the modulation data (uplink test signal) of the PUSCH channel. The second tuning parameters are consistent with the first tuning parameters on the satellite base station side.

[0176] Step S803: After receiving the uplink test signal sent by the ground simulation terminal, the onboard communication payload baseband decodes it at the effective time within the signal duration T (signal effective duration). If the decoding is correct, the parameters such as SNR, RSSI, SFN, SF measured by the decoding are packaged and sent to the onboard integrated management system. Otherwise, if the decoding CRC check error is determined, the IQ data collection instruction is triggered, and the collected IQ data is saved. The SFN and SF at the data collection time can be strictly aligned with the PPS pulse second signal, and the IQ data stored in the onboard communication payload baseband has a storage duration of not less than 2 time slots. The collected data and the corresponding demodulation parameters are packaged and sent to the onboard integrated management system, and the onboard base station switches back to the original service mode.

[0177] In step S804, the onboard integrated management system transmits the collected data and corresponding demodulation parameters back to the ground station control management system through the measurement and control link, and the ground station control management system forwards them to the ground data analysis system. The ground data analysis system preprocesses, simulates, analyzes and statistics the collected data and corresponding demodulation parameters to generate test analysis results.

[0178] In order to better illustrate this debugging method, the following also lists a quasi-service debugging process based on satellite-ground time synchronization triggering statistics access process related step parameters. Figure 10 , taking the example of a ground simulation terminal accessing a satellite base station, where the satellite base station and the ground simulation terminal each record key parameters of the entire access process to assist in analyzing nodes where problems may occur in the initial access process. In this embodiment, the satellite base station is in a quasi-service process commissioning mode and, based on the 5G communication protocol, records key nodes and signaling information interaction content statistics of the terminal access network process, including the initial random access MSG1 to MSG5 recording information, etc., and the ground simulation terminal also records the MSG1 to MSG5 indicators at the same time. The specific steps and characteristics are as follows:

[0179] Step S901: After the on-orbit satellite enters the communication field of view of the ground station measurement and control system and the ground simulation terminal, the ground station measurement and control system establishes a link with the onboard measurement and control system;

[0180] In step S902, the ground station control and management system outputs third tuning parameters to the onboard integrated management system via the measurement and control link. The third tuning parameters include:

[0181] The working mode of the satellite base station is configured as quasi-business process commissioning mode (quasi-business commissioning mode);

[0182] The parameters of the onboard communication payload array antenna that need to be adjusted to point to the ground simulation terminal include beam ID, angle pointing, effective time, and signal duration T;

[0183] Parameters such as the beam direction required for the onboard communication payload baseband to perform quasi-business process commissioning mode, the timestamp when the ground simulation terminal starts sending business data, and the signal duration T;

[0184] The onboard integrated management system timely triggers the third tuning parameter to the onboard base station. The onboard communication payload baseband confirms the validity of the third tuning parameter and switches to the quasi-business process tuning mode. The confirmation and effectiveness information (second confirmation and effectiveness information) of the quasi-business process tuning mode is fed back to the onboard integrated management system.

[0185] The onboard integrated management system feeds back the confirmation and effectiveness information of the quasi-business process debugging mode to the ground station control and management system through the onboard measurement and control system;

[0186] Step S903: After receiving the confirmation information from the satellite, the ground station control and management system sends the fourth commissioning parameter to the ground simulation terminal to perform the terminal access process;

[0187] Step S904: After receiving the third test parameter, the onboard communication payload baseband records the first process data within the signal duration T, including:

[0188] Demodulate SFN, SLOT, received power RSSI, SNR, TA, and PREAMBLE ID at the time of MSG1 demodulation;

[0189] SFN, SLOT, and TA at the time of sending MSG2, SFN and SLOT at which MSG3 is expected to be received, and the number and location of resource RBs allocated to MSG3;

[0190] Demodulate SFN, SLOT, TA, received power, and SNR at the time of MSG3 demodulation;

[0191] SFN and SLOT of the time when MSG4 is sent, and SFN and SLOT of the time when ACK is received;

[0192] SFN, SLOT, received power, SNR, and number of decoded SRs at the time of demodulation of MSG5;

[0193] Send DCI, UCI time SFN, SLOT, and send stream parameters.

[0194] After the signal duration T ends, the commissioning is completed, the collected first process data is packaged and sent to the onboard integrated management component system, and the onboard base station switches back to the original service mode;

[0195] The onboard integrated management system transmits the collected first process data back to the ground station control and management system through the measurement and control link;

[0196] The ground station control and management system sends the collected first process data to the ground data analysis system;

[0197] At step S905, after receiving the confirmation information of the quasi-business process commissioning mode from the satellite, the ground station control and management system sends the fourth commissioning parameter to the ground simulation terminal. The ground simulation terminal executes the terminal access process within the signal duration T. The ground simulation terminal records the second process data, including:

[0198] SFN, SLOT, received power, and SNR at the time of decoding SSB, SIB1, and SIB19;

[0199] SFN, SLOT, transmit power RSSI, and PREAMBLE ID at the time MSG1 is sent;

[0200] Decode the SFN and SLOT of MSG2, send the SFN and SLOT of MSG3, and the number and location of the allocated resource RBs of MSG3;

[0201] SFN, SLOT, transmit power, and cumulative number of times when MSG3 is sent;

[0202] Decode the SFN, SLOT, and CRC results of MSG4 at the moment of decoding;

[0203] SFN and SLOT of sending ACK;

[0204] SFN, SLOT, transmit power, and SNR at the time MSG5 is sent;

[0205] SFN and SLOT of the sending SR;

[0206] SFN and SLOT at the time of decoding DCI and UCI, and the bitstream parameters when the decoding is correct.

[0207] When the signal duration T ends and the test is completed, the ground simulation terminal packages the collected second process data and sends it to the ground station control and management system;

[0208] Step S906: The ground station control and management system sends the second process data collected by the ground simulation terminal to the ground data analysis system;

[0209] In step S907, the ground data analysis system performs offline analysis on the first process data and the second process data recorded by both ends of the satellite and the ground within the same signal duration T, and generates a test analysis result.

[0210] In the above-mentioned satellite-borne base station commissioning method applicable to low-orbit satellite communication systems, the satellite-borne base station supports switching between business mode and commissioning mode (or quasi-business mode), and can configure the test method according to instructions to ensure that the test is not interfered with, thereby achieving accurate commissioning of the satellite-borne base station.

[0211] Moreover, the satellite-borne base station can simulate sending downlink test signals to the ground simulation terminal or receiving and demodulating uplink test signals. The ground simulation terminal cooperates with the satellite-borne base station to send uplink test signals or receive and demodulate downlink test signals through the ground station control and management system. It can simulate various specific communication scenarios and perform adjustments for different communication scenarios to achieve reliable adjustment of the satellite-borne base station under different communication scenarios.

It can more comprehensively analyze and monitor abnormal behavior of the air interface, accurately predict communication faults, and improve the efficiency and flexibility of on-orbit testing. The acquired commissioning data facilitates problem location and troubleshooting, and improves the accuracy of payload communication fault diagnosis. Through the analysis of captured data and key performance indicator (KPI) statistical indicators, it provides an optimization reference for improving channel simulation tuning of low-orbit satellite communications and improving the communication quality between ground terminals and satellite base stations.
