[0080] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0081] A method for obtaining fault information disclosed in an embodiment of the present application is applied to a server, such as Figure 1 As shown, the process includes: step 110 to step 130.

[0082] Step 110: Acquire the working status data of the HPRRU in real time.

[0083] The fault information acquisition method described in the embodiment of the present application is applied to a network management system and is executed on a server side (such as a cloud platform) of the network management system. The network management system also includes: an HPRRU. The HPRRU described in the embodiment of the present application is obtained by improving the HPRRU in the prior art.

[0084] The HPRRU is connected to a HUB (hub) via an optical fiber to receive network signals via the HUB; on the other hand, the HPRRU is connected to the server for communication to report monitoring data to the server and receive device protection instructions sent by the server.

[0085] like Figure 2 As shown, the HPRRU described in the embodiment of the present application includes: a space environment wireless signal receiving antenna 210, a PRRU (Picro-Remote Radio Unit) 220, a plurality of parallel preamplifiers 230 for receiving the output signal of the PRRU, a signal selection module 240, a signal processing unit 250, an optoelectronic conversion module 260, and a data transmission module 270. The specific implementation methods of each component of the HPRRU are described below.

[0086] The space environment wireless signal receiving antenna 210 is used to receive wireless signals from the space environment and send them to the signal processing unit 250. In some embodiments of the present application, the space environment wireless signal receiving antenna 210 may be an ORX observation antenna.

[0087] The specific implementation of PRRU 230 can be found in the prior art and will not be described in detail here.

[0088] In some embodiments of the present application, the preamplifier 230 is also called an "integrated PA (Pre-Amplifier)". The specific implementation of the preamplifier can be found in the prior art and will not be described in detail in the embodiments of the present application.

[0089] The signal selection module 240 is used to select and collect the signal output by the PRRU 230 to the designated preamplifier 230 according to the control signal of the signal processing unit 250. In some embodiments of the present application, the signal selection module 240 can be implemented by a radio frequency switch. For example, the signal selection module 240 can be implemented by a radio frequency single-pole double-throw (SPDT) switch, and the signal processing unit 250 outputs a control signal to the switch control terminal of the radio frequency single-pole double-throw switch through a universal input and output interface, so that the signal selection module 240 selects the input signal of the preamplifier 230 currently being collected.

[0090] In some embodiments of the present application, each of the preamplifiers 230 is connected to the PRRU via a coupler. The coupler is used to couple the signal output by the PRRU to the signal selection module 240 .

[0091] In some embodiments of the present application, the working status data of the HPRRU includes: first working status data and second working status data, and the first working status data is obtained by the HPRRU through the following method: time-sharing the signal output by the PRRU to each of the preamplifiers, and the space environment wireless signal collected by the space environment wireless signal receiving antenna, and performing signal analysis and processing to obtain the first working status data of the HPRRU.

[0092] Specifically, the signal processing unit 250 performs signal analysis and processing on the signal output by the PRRU to each of the preamplifiers and the space environment wireless signal collected by the space environment wireless signal receiving antenna in a time-sharing manner to obtain the first working state data of the HPRRU. For example, the signal processing unit 250 is used to perform signal processing and analysis on the signal sent by the space environment wireless signal receiving antenna 210 and the signal sent by the signal selection module 240 in a time-sharing manner to obtain one or more of the following working state data of the HPRRU: dual-stream subcarrier power, number of dual-stream RRC users, space environment wireless signal information, signal information detected at the PRRU 220 inside the HPRRU, and working state data of the preamplifier 230 inside the HPRRU and working state data such as the physical cell identifier as the first working state data of the HPRRU.

[0093] When the signal processing unit 250 performs signal analysis and processing, at any time, it only analyzes and processes one input signal, that is, at the same time, it only processes the spatial environment wireless signal collected by the ORX observation antenna, or, it only processes one signal collected from the PRRU coupling output (that is, the input signal of a certain preamplifier 230). Taking the PRRU coupling linking two preamplifiers 230 as an example, assuming that the signal processing unit 250 performs signal processing for a period of 160 milliseconds, the signal processing unit 250 analyzes and processes the signal collected by the ORX observation antenna in the first 160 milliseconds, analyzes and processes the signal of the PRRU coupled to one preamplifier 230 in the second 160 milliseconds, and analyzes and processes the signal of the PRRU coupled to another preamplifier 230 in the third 160 milliseconds.

[0094] The optoelectronic conversion module 260 is used to convert the optical fiber signal connected to the HPRRU into an electrical signal, and then send it to the PRRU 220 through a network cable.

[0095] The signal processing unit 250 is further configured to obtain optical input power through the photoelectric conversion module 260 as a second working state data of the HPRRU. The calculation method of optical input power can be found in the prior art and will not be described in detail in the embodiments of the present application.

[0096] The data transmission module 270 is used to upload the optical input power, dual-stream subcarrier power, dual-stream RRC, number of users, spatial environment wireless signal information, signal information detected at the PRRU inside the HPRRU, and working status data of each preamplifier inside the HPRRU, etc., obtained by the signal processing unit 250 to the service end; and transmit the device protection instruction issued by the service end to the signal processing unit 250. In some embodiments of the present application, the data transmission module 270 can be implemented based on an NB-IoT (Narrow Band Internet of Things) module.

[0097] In some embodiments of the present application, the signal processing unit 250 may further include: a dual-port input radio frequency analog-to-digital converter, a digital signal processor, and a microcontroller.

[0098] The dual-port input RF analog-to-digital converter is used to convert the wireless signal coupled from the space environment wireless signal receiving antenna 210 (such as an ORX observation antenna) or the PRRU to the signal selection module 240 into a digital signal, and then send it to the digital signal processor for analysis and processing. The dual-port input RF analog-to-digital converter can be implemented based on an RF-ADC integrated chip.

[0099] In some embodiments of the present application, the digital signal processor can be implemented based on FPGA (Field-Programmable Gate Array), and is used to analyze the digital signal collected by the dual-port input RF analog-to-digital converter to obtain RSRP (Reference Signal Receiving Power) / SINR (Signal to Interference plus Noise Ratio) / PCI (Physical Cell Identifier) / OFDM (Orthogonal Frequency Division Multiplex) subcarrier power / RRC (Radio Resource Control) connection number and other information.

[0100] The microcontroller can be implemented using an ARM chip. The microcontroller reads information such as the subcarrier power / RRC connection number of the wireless signal from the digital signal processor through interfaces such as SPI (Serial Peripheral Interface) / AXI (Advanced eXtensible Interface) / APB (Advanced Peripheral Bus), and obtains information such as the input power, output power, and output standing wave ratio of the preamplifier 230 through an RS485 bus.

[0101] In some embodiments of the present application, the microcontroller selects to adjust the output power of one or more preamplifiers according to the device protection instruction sent by the service end, or turns off the output power of all preamplifiers.

[0102] In some embodiments of the present application, the microcontroller may also issue an alarm through an external indicator light of the HPRRU to prompt a user that a fault has occurred in the current HPRRU.

[0103] In some embodiments of the present application, the data analysis and processing flow of the digital signal processor is as follows: the digital signal processor receives the digital signal from the RF analog-to-digital converter with a dual-port input, and first performs FFT transformation on the frequency domain signal; then, performs subcarrier power statistics on one frequency domain signal obtained by the FFT transformation, and then estimates the number of dual-stream RRC users based on the ratio of the number of subcarriers with power to the number of all subcarriers; on the other hand, first performs synchronization signal demodulation on the frequency domain signal obtained by the FFT transformation, and calculates the bit error rate of the demodulated synchronization signal; after the synchronization signal demodulation is completed, the downlink reference signal is further demodulated, and the bit error rate of the downlink reference signal can be calculated, and then the SINR (signal to interference plus noise ratio) of the downlink reference signal is calculated; after the downlink reference signal demodulation is completed, the downlink broadcast channel can be further demodulated, and finally, the PCI is parsed from the broadcast channel.

[0104] During the operation of the HPRRU, the HPRRU collects the space environment wireless signal in real time through the space environment wireless signal receiving antenna, performs the aforementioned signal processing, and respectively collects the real-time signal output by the PRRU to each preamplifier, performs the aforementioned signal processing, and obtains part of the working status data of the HPRRU. On the other hand, the HPRRU obtains another part of the working status data such as the optical input power in real time through the photoelectric conversion module, and uploads the obtained working status data to the server in real time.

[0105] Step 120: Acquire an application scenario matched by the HPRRU according to the working status data of the HPRRU acquired within a specified time period.

[0106] After receiving the working status data uploaded by the HPRRU in real time, the service end stores and analyzes the working status data of the HPRRU.

[0107] In some embodiments of the present application, the working status data includes: dual-stream subcarrier power, and the number of dual-stream RRC users. The obtaining of the application scenario matching the HPRRU based on the working status data of the HPRRU obtained within a specified time period includes: obtaining the application scenario matching the HPRRU based on the distribution characteristics of the dual-stream subcarrier power and the number of dual-stream RRC users of the HPRRU obtained within a specified time period.

[0108] In some embodiments of the present application, according to the distribution characteristics of the dual-stream subcarrier power and the number of dual-stream RRC users of the HPRRU obtained within a specified time period, obtaining the application scenario matching the HPRRU, including: fitting the dual-stream subcarrier power obtained within the specified time period to obtain a dual-stream subcarrier power curve; fitting the number of dual-stream RRC users to obtain a dual-stream user number curve; when both the dual-stream subcarrier power curve and the dual-stream user number curve are balanced curves, determining that the application scenario of the HPRRU is a dual-stream coverage application scenario; when at least one of the dual-stream subcarrier power curve and the dual-stream user number curve is an unbalanced curve, determining that the application scenario of the HPRRU is a single-stream coverage application scenario.

[0109] For example, a fitting process is performed on the dual-stream subcarrier powers uploaded by the HPRRU in the past specified time period to obtain a subcarrier power curve.

[0110] Similarly, the number of dual-stream RRC users uploaded by the HPRRU in the past specified time period is fitted to obtain a user number curve.

[0111] Among them, the specified time period can be one week, 10 days or 15 days, etc. Specifically, the specific value of the specified time period can be determined according to business requirements, and is not limited to this in the embodiments of the present application.

[0112] After obtaining the subcarrier power curve and the user number curve of the HPRRU, the application scenario of the HPRRU may be further determined according to the distribution characteristics of the subcarrier power curve and the user number curve.

[0113] In an embodiment of the present application, the application scenarios of the HPRRU include: dual-stream coverage application scenarios and single-stream coverage application scenarios. Specifically, when the obtained dual-stream subcarrier power curve is a balanced curve, and the dual-stream user number curve is a balanced curve, it can be determined that the application scenario of the HPRRU is a dual-stream coverage application scenario; when the obtained dual-stream subcarrier power curve is an unbalanced curve, or the dual-stream user number curve is an unbalanced curve, it can be determined that the application scenario of the HPRRU is a single-stream coverage application scenario.

[0114] Step 130: Obtain fault information of the HPRRU according to the application scenario and / or the working status data acquired in real time.

[0115] After determining the application scenario of the HPRRU, the server further determines whether the HPRRU device is working properly based on the application scenario of the HPRRU and the working status data uploaded by the HPRRU in real time. For example, in the dual-stream coverage application scenario, there is a large difference between the dual-stream subcarrier power and the number of dual-stream RRC users of the HPRRU, and it can be determined that the device is working abnormally. For another example, in the single-stream coverage application scenario, the number of single-stream or dual-stream RRC users suddenly jumps to 0, and it can be determined that the HPRRU device is working abnormally.

[0116] The fault information acquisition method disclosed in the embodiment of the present application can not only identify whether the HPRRU device is working abnormally, but also identify the fault type of the HPRRU device when it is working abnormally.

[0117] As mentioned above, the HPRRU includes multiple preamplifiers. Accordingly, the fault information acquisition method disclosed in the embodiment of the present application can determine which preamplifier has a fault and identify the specific cause of the fault.

[0118] As mentioned above, the application scenarios of HPRRU include: dual-stream coverage application scenarios and single-stream coverage application scenarios. In some embodiments of the present application, some fault judgments need to be performed in combination with the working status data in the specified application scenario. The fault judgment process is described below with examples.

[0119] In some embodiments of the present application, the working status data includes: dual-stream subcarrier power, the number of dual-stream RRC users, and the working status data of each preamplifier in the HPRRU, and the fault information of the HPRRU is obtained according to the application scenario and / or the working status data obtained in real time, including: when the application scenario is a dual-stream coverage application scenario, and the change value of the dual-stream subcarrier power is greater than a first power change threshold, and the change value of the dual-stream RRC user number is greater than a first user number change threshold, the fault information of each preamplifier in the HPRRU is determined according to the working status data of each preamplifier.

[0120] For example, when the application scenario is a dual-stream coverage application scenario, if there is a large difference in the dual-stream subcarrier power, or there is a large difference in the number of dual-stream RRC users, or there is a large difference in both the dual-stream subcarrier power and the number of dual-stream RRC users, it indicates that the HPRRU is working abnormally. The service end can further determine the cause of the fault based on the real-time working status data of each of the preamplifiers, determine the fault information matched by the HPRRU, and complete troubleshooting.

[0121] In an embodiment of the present application, the application scenario includes: a single-stream coverage application scenario, the working status data also includes: the number of single-stream RRC users or the number of dual-stream RRC users, and the working status data of each preamplifier in the HPRRU, and the fault information of the HPRRU is obtained according to the application scenario and / or the working status data obtained in real time, including: when the application scenario is a single-stream coverage application scenario, and the number of single-stream RRC users or the number of dual-stream RRC users is lower than the preset user number threshold, the fault information of each preamplifier in the HPRRU is determined according to the working status data of each preamplifier. Among them, the preset user number threshold can be 0 or other values. The preset user number threshold is set according to specific business requirements. For example, in a single-stream coverage application scenario, the number of single-stream or dual-stream RRC users suddenly jumps to 0, indicating that the HPRRU is working abnormally. The service end can further determine the cause of the fault according to the real-time working status data of each preamplifier, determine the fault information matched by the HPRRU, and complete the troubleshooting.

[0122] When the HPRRU includes multiple preamplifiers, the service end can determine whether each preamplifier is in a fault state and in which fault state according to the working status data reported by the HPRRU.

[0123] The following further describes by way of example a specific implementation method of determining the fault information of each preamplifier in the HPRRU according to the working status data of each preamplifier in a dual-stream coverage application scenario and a single-stream coverage application scenario.

[0124] In some embodiments of the present application, the working status data also includes: space environment wireless signal information, and signal information detected at the PRRU inside the HPRRU, and the determining of the fault information of each preamplifier in the HPRRU based on the working status data of each preamplifier includes: performing the following operations for each preamplifier: determining the initial screening result of the corresponding preamplifier matching according to the working status data of the preamplifier, wherein the initial screening result includes: a initial screening result indicating the fault information of the preamplifier, and a initial screening result indicating that the initial screening of the preamplifier is normal; in response to the initial screening result indicating the fault information of the preamplifier, determining the fault information of each preamplifier in the HPRRU according to the initial screening result; in response to the initial screening result indicating that the preamplifier is initially screened normally, determining the fault information of the preamplifier according to the comparison result of the space environment wireless signal information and the signal information detected at the PRRU inside the HPRRU.

[0125] In a specific application scenario, the working status data of each preamplifier inside the HPRRU includes one or more of the following: input power, output power, and output standing wave ratio. In an embodiment of the present application, the fault information of the preamplifier indicated in the preliminary screening result includes: link failure, coupler failure, preamplifier failure, output feeder or antenna failure.

[0126] As mentioned above, the working status data of the preamplifier includes: input power, output power, and output standing wave ratio. According to the working status data of the preamplifier, the initial screening result of the corresponding preamplifier matching is determined, including any one of the following methods.

[0127] The first type: when the input power of the preamplifier is less than a preset input power threshold, it is determined that the HPRRU is in a link failure state or a coupler failure state of the preamplifier. For example, if the input power of the aforementioned integrated PA (i.e., the preamplifier) ​​is low, it may be a link failure or a coupler failure from the PRRU to the integrated PA.

[0128] The second type: when the output power of the preamplifier is less than a preset output power threshold, the HPRRU is determined to be in the preamplifier fault state. For example, if the input power of an integrated PA is normal but the output power is low, it may be an integrated PA fault.

[0129] The third type: when the input power of the preamplifier is greater than or equal to the preset input power threshold, and the output power is greater than or equal to the preset output power threshold, and the output standing wave ratio is abnormal, it is determined that the HPRRU is in an output feeder or antenna failure state. For example, when the output power of the integrated PA is normal but the output standing wave ratio is abnormal, it may be an output feeder or antenna failure. The preset output power threshold is set according to specific business needs.

[0130] If the initial screening result indicates that the preamplifier is normal, then further subsequent judgment is performed. For example, when the status of the integrated PA is normal, the PCI and SINR obtained by the signal analysis detected by the ORX observation antenna (i.e., the space environment wireless signal receiving antenna) can be further read and compared with the PCI and SINR of the PRRU coupling. If the PCI is inconsistent or the SINR of the ORX observation antenna is poor, it may be an integrated PA failure; if both are normal, it may be an antenna failure.

[0131] The fault information acquisition method disclosed in the embodiment of the present application can also identify other faults of the HPRRU. The following is an example of identifying other faults of the HPRRU.

[0132] In some embodiments of the present application, the working status data also includes one or more of the following: dual-stream subcarrier power, the number of dual-stream RRC users, optical input power, spatial environment wireless signal information, and signal information detected at the PRRU inside the HPRRU. The fault information of the HPRRU is obtained according to the application scenario and / or the working status data obtained in real time, and also includes any one or more of the following: determining whether the HPRRU is in a fiber fault state according to the optical input power; determining whether the HPRRU is in a network fault state according to the optical input power and the number of dual-stream RRC users; when the application scenario is a dual-stream coverage application scenario, determining whether the HPRRU is in a network coverage range fault state according to a comparison result of the dual-stream RRC user number obtained in real time with the dual-stream RRC user number within a specified time period; determining whether the HPRRU is in a signal-to-noise ratio fault state according to a comparison result of the spatial environment wireless signal information and the signal information detected at the PRRU inside the HPRRU.

[0133] For example, when the optical input power of the optoelectronic conversion module of the HPRRU device obtained by the server in real time is lower than the historical value, it can be determined as an optical fiber transmission failure. The historical value can be the average value of the optical input power received in the specified time period.

[0134] For example, when the optical input power obtained in real time by the server is greater than or equal to the historical value, if the number of dual-stream users of the HPRRU device obtained in real time by the server decreases and remains at 0, it can be considered that the HPRRU is in a network failure state.

[0135] For another example, when the application scenario of the HPRRU is a dual-stream coverage application scenario, if the current number of dual-stream RRC users of the HPRRU obtained by the server is significantly reduced compared with the number of historical dual-stream RRC users, it can be considered that the HPRRU is in a network coverage failure state. The number of historical dual-stream RRC users can be an average number of dual-stream RRC users in a specified time period.

[0136] For another example, when the SINR of the space environment wireless signal received by the space environment wireless signal receiving antenna (such as the ORX observation antenna) is inconsistent with the SINR of the signal output by the PRRU to each preamplifier, it indicates that the signal-to-noise ratio is poor, that is, the HPRRU is in a signal-to-noise ratio failure state. Alternatively, when the PCI in the signal received by the space environment wireless signal receiving antenna is inconsistent with the PCI in the signal output by the PRRU to each preamplifier, it indicates that the PCI is abnormal, that is, the HPRRU is in a signal-to-noise ratio failure state.

[0137] According to the above method, it is possible to identify whether the HPRRU is in a fault state and to identify which fault state the HPRRU is in.

[0138] The fault information acquisition disclosed in the embodiment of the present application can also automatically eliminate the specified fault after identifying that the HPRRU is in a preset fault state. The preset fault state is a fault that can be automatically eliminated, and the preset fault state is set according to the control circuit performance and business requirements of the HPRRU. For example, the preset fault state includes: output feeder fault, antenna fault, link fault, coupler fault, and preamplifier fault.

[0139] Reference Figure 3 , the fault information acquisition method disclosed in the embodiment of the present application also includes: step 140.

[0140] Step 140: In response to the fault information indicating that the specified preamplifier is in a preset fault state, send a device protection instruction to the HPRRU, so that the HPRRU adjusts the output power of the corresponding preamplifier in the HPRRU in response to the device protection instruction.

[0141] After the service end identifies that the HPRRU is working abnormally and further identifies that the HPRRU is in the above-mentioned preset fault state, that is, the preamplifier of the HPRRU (such as the aforementioned integrated PA) is in a fault state, the service end automatically sends a device protection command to the HPRRU to put the HPRRU into protection mode.

[0142] In some embodiments of the present application, the device protection instruction may carry identification information of the preamplifier in a faulty state. Accordingly, the HPRRU selects to adjust the output power of one or more preamplifiers (such as the aforementioned integrated PA) based on the identification information in the received device protection instruction. For example, the preamplifier in a faulty state is turned off.

[0143] In some embodiments of the present application, after the service end identifies that the HPRRU is working abnormally and further identifies that the HPRRU is in a fault state, the fault information is pushed to relevant maintenance personnel, or the fault information and solution are pushed, so as to achieve the purpose of timely discovering the HPRRU and quickly resolving the HPRRU fault.

[0144] The fault information acquisition method disclosed in the embodiment of the present application is applied to the server, and obtains the working status data of the HPRRU in real time; obtains the application scenario matched by the HPRRU according to the working status data of the HPRRU obtained within a specified time period; obtains the fault information of the HPRRU according to the application scenario and / or the working status data obtained in real time, and can identify various network faults of the HPRRU to improve the comprehensive monitoring of the working status of the HPRRU by the network management system.

[0145] The fault information acquisition method disclosed in the embodiment of the present application collects and analyzes the signals output by the PRRU to each preamplifier in the HPRRU, as well as the wireless signals of the space environment, and performs signal analysis and processing to obtain the real-time working status data of the HPRRU, and uploads it to the server of the network management system. Then, the server intelligently identifies whether the HPRRU device has fault information such as preamplifier fault, weak coverage field strength, poor SINR, PCI abnormality, optical fiber or network fault, etc. based on the real-time working status data of the HPRRU and the historical working status data, thereby realizing comprehensive monitoring of the working status of the HPRRU by the network management system.

[0146] Furthermore, the fault information acquisition method disclosed in the embodiment of the present application acquires and identifies the fault information of a single preamplifier by collecting and analyzing the signals of each preamplifier in the HPRRU in a time-sharing manner. Moreover, after the service end identifies that a preamplifier has a fault, it can also automatically issue a device protection instruction, so that the corresponding device enters a protection mode. At the same time, it can notify the relevant maintenance personnel to handle it, which significantly reduces the difficulty and cost of equipment maintenance.

[0147] Accordingly, the embodiment of the present application also discloses a method for acquiring fault information, which is applied to an HPRRU, wherein the HPRRU comprises: a PRRU, a plurality of preamplifiers for receiving output signals of the PRRU, a signal selection module for collecting signals output by the PRRU to each of the preamplifiers, and a space environment wireless signal receiving antenna, such as Figure 4 As shown, the method includes: steps 410 to 440.

[0148] Step 410: According to a preset time-sharing signal analysis and processing cycle, the space environment wireless signals collected by the space environment wireless signal receiving antenna are collected respectively, or a signal output by the PRRU to each of the preamplifiers is selected to be collected.

[0149] The preset time-sharing signal analysis and processing cycle is the cycle for processing one signal. The HPRRU collects and processes the wireless signals of the space environment in turn according to the preset time-sharing signal analysis and processing cycle, as well as the signals input to each preamplifier by the PRRU. In an embodiment of the present application, the preset time-sharing signal analysis and processing cycle is set according to the signal processing capability and monitoring accuracy of the aforementioned HPRRU. As mentioned above, the preset time-sharing signal analysis and processing cycle can be 160 milliseconds.

[0150] The specific implementation of the HPRRU collecting the space environment wireless signal received by the space environment wireless signal receiving antenna and the signal output by the PRRU to each of the preamplifiers is as described above and will not be repeated here.

[0151] Step 420: Perform signal analysis processing on the collected signal to obtain first working state data of the HPRRU.

[0156] The specific implementation manner of the HPRRU uploading the second working status data acquired in real time to the server and the first working status data obtained by real-time analysis is as described above and will not be repeated here.

[0157] After receiving the working status data uploaded by the HPRRU, the service end stores the working status data and obtains the application scenario matched by the HPRRU according to the working status data of the HPRRU obtained within a specified time period. Afterwards, the service end obtains the fault information of the HPRRU according to the application scenario and / or the working status data obtained in real time.

[0158] The specific implementation method of the server obtaining the application scenario matching the HPRRU according to the working status data of the HPRRU obtained within a specified time period is described above and will not be repeated here.

[0159] The specific implementation method of the server obtaining the fault information of the HPRRU according to the application scenario and / or the working status data obtained in real time is described above and will not be repeated here.

[0160] In some embodiments of the present application, after uploading the first working status data and the second working status data as the working status data of the HPRRU to the server corresponding to the HPRRU in real time, the method further includes: in response to receiving a device protection instruction issued by the server, adjusting the output power of the corresponding preamplifier in the HPRRU. For example, turning off the output power of the preamplifier in a fault state.

[0161] The specific implementation manner of the HPRRU adjusting the output power of the corresponding preamplifier in the HPRRU based on the device protection instruction issued by the server is as described above and will not be repeated here.

[0162] The fault information acquisition method disclosed in the embodiment of the present application is applied to HPRRU. The HPRRU collects and analyzes the signals output by the PRRU to each preamplifier in the HPRRU, as well as the wireless signals of the space environment, and performs signal analysis and processing to obtain the real-time working status data of the HPRRU, and uploads it to the server of the network management system. Then, the server intelligently identifies whether the HPRRU device has preamplifier failure, weak coverage field strength, poor SINR, PCI abnormality, optical fiber or network failure and other fault information based on the real-time working status data of the HPRRU and the historical working status data, thereby realizing the comprehensive monitoring of the working status of the HPRRU by the network management system.

[0163] Furthermore, the fault information acquisition method disclosed in the embodiment of the present application acquires and identifies the fault information of a single preamplifier by collecting and analyzing the signals of each preamplifier in the HPRRU in a time-sharing manner. Moreover, after the service end identifies that a preamplifier has a fault, it can also automatically issue a device protection instruction, so that the corresponding device enters the protection mode. At the same time, it can notify the relevant maintenance personnel to handle it, which significantly reduces the difficulty and cost of equipment maintenance.
