[0091] 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.

[0092] The data collection method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown in the figure, the terminal 102 communicates with the SF 104 via the network. The data storage system can store the data that the SF 104 needs to process. The data storage system can be integrated on the SF 104, or it can be placed on the cloud or other network servers. The SF receives the collected data and self-test data sent by the terminal by sending data collection instructions and terminal quality inspection policies to the terminal; and performs quality inspection and evaluation on the collected data based on the self-test data to obtain a quality inspection and evaluation result; then, if the quality inspection and evaluation result is passed, the quality inspection and evaluation result and the collected data are sent to the application function entity AF through the network open function network element NEF.

[0093] In one embodiment, Figure 2 As shown, a data acquisition method is provided, which is applied to Figure 1 Taking SF104 in the example as an example, the following steps are included:

[0094] S201, sending data collection instructions and terminal quality inspection strategies to the terminal.

[0095] The data collection instruction is used to instruct the terminal to perform data collection operations to obtain collected data; the terminal quality inspection strategy is used to instruct the terminal to perform self-inspection operations on terminal-related parameters to obtain self-inspection data.

[0096] It should be noted that the terminal quality inspection policy may record the quality inspection requirements for the collected data. Therefore, before sending the terminal quality inspection policy to the terminal, the quality inspection accuracy requirements for the collected data may be obtained in advance. Then, according to the actual quality inspection accuracy requirements, the corresponding terminal quality inspection policy may be constructed. The terminal quality inspection policy may include but is not limited to: quality monitoring parameters, quality control parameters, emergency strategies and self-inspection frequency, etc.

[0097] To further illustrate, the data collection instruction may record the data type requirements and data volume requirements for the sampled data. Therefore, before sending the data collection instruction to the terminal, the data collection requirements for the collected data may be obtained in advance, and then, the corresponding data collection instruction may be constructed based on the actual data collection requirements.

[0098] S202: Receive collected data and self-test data sent by the terminal.

[0099] In one embodiment of the present application, in order to ensure the timeliness of the collected data, the receiving waiting time for the collected data and self-test data can be pre-set. After sending the data collection instruction and the terminal quality inspection policy to the terminal, the timer is started. If the collected data and self-test data sent by the terminal are received within the receiving waiting time, subsequent operations are performed based on the collected data and self-test data. If the collected data and self-test data sent by the terminal are received outside the receiving waiting time, the operation of sending the data collection instruction and the terminal quality inspection policy to the terminal is executed again to ensure that the collected data and self-test data sent by the terminal are received within the receiving waiting time.

[0100] S203: Perform quality inspection and evaluation on the collected data based on the self-inspection data to obtain a quality inspection and evaluation result.

[0101] It should be noted that when it is necessary to conduct quality inspection and evaluation on the collected data, the quality inspection and evaluation operations can be performed from multiple dimensions, and then the quality inspection and evaluation results of multiple dimensions can be summarized. The summary result is the quality inspection and evaluation result.

[0102] Multi-dimensional quality inspection and assessment operations include at least one of the following: integrity assessment, timeliness assessment, unexpected trend change assessment, consistency assessment, and data desensitization assessment. These multi-dimensional quality inspection and assessment operations can be configured or adjusted based on actual quality inspection needs. The specific types of quality inspection operations included in these multi-dimensional quality inspection and assessment operations are not limited here.

[0103] In one embodiment of the present application, when it is necessary to perform a quality inspection and evaluation on the collected data based on the self-inspection data, the following contents may be included: performing a business value evaluation on the collected data based on preset business logic rules to obtain a business value evaluation result; performing an integrity evaluation and a timeliness evaluation on the collected data based on the self-inspection data to obtain an integrity evaluation result and a timeliness evaluation result; performing an unexpected trend change evaluation on the collected data to obtain an abnormal data evaluation result; performing a consistency evaluation on the collected data based on historical data of the same period to obtain a consistency evaluation result; performing a data desensitization evaluation on the collected data based on preset sensitive data to obtain a data desensitization evaluation result; and determining the quality inspection evaluation result based on the integrity evaluation result, the abnormal data evaluation result, the consistency evaluation result, the timeliness evaluation result and the data desensitization evaluation result.

[0104] Among them, business value assessment is to ensure that data complies with predefined business rules and logical relationships; evaluate the impact of data on key performance indicators (KPIs); integrity assessment is used to detect whether the data collection process is complete and uninterrupted; check whether the data is lost or tampered with during transmission; identify potential data processing problems through system logs; timeliness assessment is to use clustering algorithms to identify data points that deviate significantly from the normal distribution range; detect unexpected trend changes in data sequences; verify whether the data conforms to the expected statistical distribution; discover sudden changes or breakpoints in the data; consistency assessment is to conduct comparative analysis with historical data of the same period; evaluate the consistency of adjacent or similar terminal data; or compare with other data sources of the same type to achieve the purpose of abnormal data evaluation; timeliness assessment is to evaluate the time delay from data generation to availability; monitor whether the frequency of data updates meets business needs; data desensitization assessment is to evaluate the effectiveness of data desensitization measures; and ensure that data processing complies with relevant laws and policies.

[0105] S204: When the quality inspection and evaluation result is passed, the quality inspection and evaluation result and the collected data are sent to the application function entity AF via the network open function element NEF.

[0106] In one embodiment of the present application, when the quality inspection evaluation result is passed, a summary description of the collected data can be added to the quality inspection evaluation result to ensure that the user can more intuitively understand the collection quality of the collected data.

[0107] The above-mentioned data collection method receives the collected data and self-inspection data sent by the terminal by sending data collection instructions and terminal quality inspection strategies to the terminal; and performs quality inspection and evaluation on the collected data based on the self-inspection data to obtain the quality inspection and evaluation results; and then, when the quality inspection and evaluation results are passed, the quality inspection and evaluation results and the collected data are sent to the application function entity AF through the network open function network element NEF. According to the above content, it can be seen that in the process of data collection, this application will not only obtain the collected data through the data collection operation, but also simultaneously perform self-inspection operations on the terminal-related parameters to obtain self-inspection data; thereby achieving quality inspection and evaluation of the collected data through self-inspection data, ensuring that the collection quality of the collected data is effectively recorded during the data collection process, so that the operation and maintenance personnel can timely and effectively discover data quality problems of the collected data based on the quality inspection and evaluation results, prevent decision delays and waste of collected data, and meet the high-quality collection requirements of the sampled data, as well as the related requirements of the integrity, reliability and timeliness of the collected data.

[0108] In one embodiment, if Figure 3As shown, the terminal quality inspection policy includes the first quality inspection policy and the second quality inspection policy. Therefore, when it is necessary to send a data collection instruction and a terminal quality inspection policy to the terminal, the following contents may be included:

[0109] S301: Send non-access stratum (NAS) signaling to the terminal through the access and mobility management function (AMF).

[0110] The NAS signaling includes SF connection information and a first quality inspection strategy; the NAS signaling is used to instruct the terminal to establish a communication connection channel with the SF according to the SF connection information; the first quality inspection strategy includes quality monitoring parameters and self-inspection frequency.

[0111] It should be noted that the quality monitoring parameter is used to characterize the type of relevant parameters that the terminal needs to report, and the quality monitoring parameter can be used to reflect the data quality of the collected data. The self-test frequency is used to characterize the self-test cycle of the terminal's self-test operation.

[0112] Furthermore, the NAS signaling also includes a quality monitoring flag, which is used to instruct the terminal to start a quality self-check function.

[0113] S302: Send a data collection instruction and a second quality inspection strategy to the terminal based on the communication connection channel.

[0114] The second quality inspection strategy includes quality control parameters and emergency strategies.

[0115] Specifically, the quality control parameters are used to characterize the anomaly detection threshold of the collected data and the calibration starting conditions of the calibration operation corresponding to the collected data. The specific content of the quality control parameters is not limited here; the emergency strategy is used to characterize the processing strategy when the terminal encounters specific quality problems during the data collection operation, such as terminal restart, sensor recalibration, or backup sensor switching.

[0116] The above-mentioned data collection method realizes the sending of SF connection information and the first quality inspection policy by sending NAS signaling, ensuring that a communication connection channel can be established based on the SF connection information and the second quality inspection policy can be received based on the communication connection channel. The terminal is thereby instructed to perform a self-inspection operation on terminal-related parameters according to the first quality inspection policy and the second quality inspection policy, thereby providing a judgment basis for the subsequent quality inspection and evaluation of the collected data.

[0117] In one embodiment, if Figure 4 As shown, when the quality inspection evaluation results include abnormal evaluation results, they may include the following:

[0118] S401: If the quality inspection evaluation result includes an abnormal evaluation result whose result type is an abnormal type, determine a parameter adjustment instruction for the abnormal evaluation result.

[0119] It should be noted that the quality inspection evaluation result may include at least one sub-evaluation result. Each sub-evaluation result may have different result types according to the actual result content. The result type may include normal type and abnormal type. Among them, the abnormal type may also include minor problem type, medium problem type and serious problem type.

[0120] Specifically, if the result type of the abnormal assessment result is a minor problem type, the parameter adjustment instruction can be to record and monitor without immediate intervention, and apply the Bayesian cumulative probability model to continuously evaluate the development trend of the problem; if the result type of the abnormal assessment result is a medium problem type, the parameter adjustment instruction can be to use the reinforcement learning algorithm to generate the optimal parameter adjustment suggestion, which is sent to the terminal by SF; if the result type of the abnormal assessment result is a serious problem type, the parameter adjustment instruction can be to trigger the emergency intervention process, automatically select the most appropriate intervention strategy, and perform operations such as terminal restart, sensor recalibration, or backup sensor switching.

[0121] S402: Send the parameter adjustment instruction to the terminal.

[0122] Among them, the parameter adjustment instruction is used to instruct the terminal to adjust the parameters so that the result type of the abnormal assessment result is changed from an abnormal type to a normal type; the parameter adjustment instruction includes the parameter to be adjusted and the parameter target value, the adjustment priority of the parameter to be adjusted, the adjustment time requirement of the parameter to be adjusted, and the parameter verification method after the parameter to be adjusted is adjusted.

[0123] S403: After the parameters are adjusted, the process returns to executing the operation of receiving the collected data and self-test data sent by the terminal.

[0124] It should be noted that after the terminal adjusts the parameters, the collected data and self-test data after the adjustment, as well as the collected data and self-test data before the adjustment, can be fed back to SF; so that SF can compare the adjusted data with the data before the adjustment, so that SF can locate abnormal data more quickly and determine whether the adjusted data still needs secondary parameter adjustment.

[0125] In an embodiment of the present application, after determining that the terminal does not need to perform secondary parameter adjustment, the quality inspection and evaluation results and the collected data are sent to the NEF, so that the NEF sends the quality inspection and evaluation results and the collected data to the AF.

[0126] When NEF sends the quality inspection and evaluation results and collected data to AF, it will generate a quality assurance certificate for the collected data. The quality assurance certificate contains the self-inspection time information for the collected data and a summary description of the quality inspection and evaluation results to ensure that operation and maintenance personnel can quickly understand the specific content of the quality inspection and evaluation results through the quality assurance certificate without having to read the quality inspection and evaluation results in detail.

[0127] The above-mentioned data collection method determines the parameter adjustment instructions of the abnormal evaluation results so that the parameters of the terminal can be adjusted through the parameter adjustment instructions. When the quality inspection and evaluation results contain abnormal evaluation results whose result types are abnormal, the parameters of the terminal can be adjusted in time, so that the terminal can perform secondary data collection operations in time, and the operation and maintenance personnel can discover data quality problems of the collected data in a timely and effective manner according to the quality inspection and evaluation results, prevent decision delays and waste of collected data, and meet the high-quality collection needs of sampled data, as well as the relevant requirements of the integrity, reliability and timeliness of the collected data.

[0128] In one embodiment, if Figure 5 As shown, when you need to generate a terminal quality inspection policy, you can include the following:

[0129] S501: Receive a sensing service request sent by AF.

[0130] The perception service request includes the perception service quality requirements; specifically, the perception service quality requirements include accuracy requirements, real-time requirements, integrity requirements, etc.

[0131] S502: After the AF passes the identity authentication, a terminal quality inspection policy is generated according to the perceived service quality requirements.

[0132] In one embodiment of the present application, the AF sends a perception service request containing perception service quality requirements to the NEF. After the NEF authenticates the perception service request, it selects a suitable SF, adds a data quality requirement tag in the request, and forwards the request to the SF; after the SF receives the perception service request, it verifies the identity authority of data quality monitoring with the unified data management (UDM) to confirm whether the AF has the right to perform data quality monitoring and parameter adjustment on the designated terminal; after the AF's identity authentication is passed, it generates a terminal quality inspection policy based on the perception service quality requirements; the SF sends a reception response to the NEF; and the NEF sends a reception response to the AF.

[0133] The above data collection method realizes the generation of terminal quality inspection strategy by receiving the perception service request sent by AF, provides a prerequisite for the subsequent generation of collection data and self-inspection data, and ensures the smooth generation of subsequent content.

[0134] In another embodiment of the present application, the present application may deploy a Data Quality Monitoring Engine (DQME) in the SF, which has the following functional modules: Quality indicator calculation module: real-time calculation of indicators such as accuracy, completeness, consistency, and timeliness of perception data. Anomaly detection module: identifies data anomalies through statistical analysis and machine learning algorithms. Parameter adjustment module: generates dynamic adjustment strategies for perception parameters. When reporting perception data, the perception terminal also reports data quality self-test information, including but not limited to: sensor status information: functional status, calibration status, interference level;

[0135] Collect environmental information: environmental factors such as temperature, humidity, and light; resource status information: battery power, processor load, and memory usage; error estimation information: measurement error estimation based on sensor characteristics.

[0136] DQME performs real-time quality assessment on the received perception data and generates quality scores and quality reports. The assessment dimensions include: data accuracy: deviation level, noise ratio; data integrity: sampling completeness, missing rate; data consistency: consistency with historical data, consistency with adjacent terminals; data timeliness: delay from collection to reporting, timestamp deviation.

[0137] When DQME detects that the quality of perception data is lower than the preset threshold, it triggers the quality optimization process: generating targeted parameter adjustment strategies; issuing parameter adjustment instructions to the perception terminal through SF; the perception terminal dynamically adjusts the acquisition parameters and processing strategies according to the instructions; continuously monitors the adjusted data quality to form a closed-loop control; DQME regularly generates data quality trend analysis reports to identify potential quality risks and provide quality warning information to the network management system.

[0138] In one embodiment, Figure 6 As shown, a data acquisition method is provided, which is applied to Figure 1 Taking the terminal 102 in FIG. 1 as an example, the method includes the following steps:

[0139] S601, receiving data collection instructions and terminal quality inspection strategies sent by SF.

[0140] In one embodiment of the present application, since the terminal quality inspection policy includes the first quality inspection policy and the second quality inspection policy, when it is necessary to receive the data collection instruction and the terminal quality inspection policy sent by the SF, the following contents may be included: receiving NAS signaling sent by the SF through the AMF; wherein the NAS signaling includes SF connection information and the first quality inspection policy; establishing a communication connection channel with the SF according to the SF connection information; and receiving the data collection instruction and the second quality inspection policy sent by the SF through the communication connection channel.

[0141] Furthermore, the NAS signaling also includes a quality monitoring identifier.

[0142] Therefore, before performing a self-test operation on terminal-related parameters according to the terminal quality inspection policy and obtaining self-test data, the method further includes: starting a quality self-test function according to the quality monitoring identifier.

[0143] S602: Execute data collection operations according to the data collection instruction to obtain collected data.

[0144] S603: Perform a self-test operation on terminal-related parameters according to the terminal quality inspection policy to obtain self-test data.

[0145] S604: Send the collected data and self-test data to SF, so that SF can perform quality inspection and evaluation based on the collected data and self-test data to obtain the quality inspection and evaluation result. If the quality inspection and evaluation result is passed, the quality inspection and evaluation result and the collected data are sent to AF through NEF.

[0146] In one embodiment of the present application, when data collection is required, Figure 7 As shown, it specifically includes the following contents: 1. AF sends a perception service request containing perception service quality requirements to NEF.

[0147] 2. After NEF authenticates the perception service request, it selects the appropriate SF, adds the data quality requirement tag to the request, and forwards the request to the SF.

[0148] 3. After receiving the perception service request, SF verifies the identity authority of data quality monitoring with the unified data management (UDM) to confirm whether AF has the authority to perform data quality monitoring and parameter adjustment on the designated terminal.

[0149] 4. SF sends a receive response to NEF.

[0150] 5. NEF sends a receive response to AF.

[0151] 6. After the AF's identity authentication is passed, the SF initializes the data quality monitoring engine (DQME), executes the AMF and perception terminal selection, and the SF generates the terminal quality inspection policy according to the perception service quality requirements.

[0152] 7. Send non-access layer NAS signaling to the terminal through the access and mobility management function entity AMF; wherein the NAS signaling includes SF connection information and the first quality inspection policy.

[0153] 8. The terminal receives NAS signaling.

[0154] 9. The terminal establishes a communication connection channel with the SF according to the SF connection information, and the terminal starts the quality self-check function according to the quality monitoring identifier.

[0155] 10. SF sends data collection instructions and the second quality inspection strategy to the terminal based on the communication connection channel.

[0156] 11. The terminal performs a data collection operation to obtain collected data; the terminal performs a self-test operation on terminal-related parameters to obtain self-test data.

[0157] 12. The terminal sends the collected data and self-test data to SF.

[0158] 13. After receiving the data, SF's DQME performs quality inspection and evaluation on the collected data based on the self-inspection data to obtain the quality inspection and evaluation results.

[0159] 14. Based on the quality inspection and evaluation results, the DQME of SF determines that the result type is an abnormal evaluation result of an abnormal type, and then determines the parameter adjustment instructions for the abnormal evaluation result.

[0160] 15. After receiving the parameter adjustment instruction, the terminal performs the corresponding adjustment operation.

[0161] 16. After adjusting the parameters, the terminal sends an adjustment confirmation message to SF, along with the collected data and self-test data before and after the adjustment.

[0162] 17. SF transmits the data quality report together with the processed high-quality perception results to NEF.

[0163] 18. When NEF transmits the perception results to AF, it also provides quality assurance certificates, enabling AF to assess data credibility and business risks.

[0164] The above-mentioned data collection method receives the collected data and self-inspection data sent by the terminal by sending data collection instructions and terminal quality inspection strategies to the terminal; and performs quality inspection and evaluation on the collected data based on the self-inspection data to obtain the quality inspection and evaluation results; and then, when the quality inspection and evaluation results are passed, the quality inspection and evaluation results and the collected data are sent to the application function entity AF through the network open function network element NEF. According to the above content, it can be seen that in the process of data collection, this application will not only obtain the collected data through the data collection operation, but also simultaneously perform self-inspection operations on the terminal-related parameters to obtain self-inspection data; thereby achieving quality inspection and evaluation of the collected data through self-inspection data, ensuring that the collection quality of the collected data is effectively recorded during the data collection process, so that the operation and maintenance personnel can timely and effectively discover data quality problems of the collected data based on the quality inspection and evaluation results, prevent decision delays and waste of collected data, and meet the high-quality collection requirements of the sampled data, as well as the related requirements of the integrity, reliability and timeliness of the collected data.
