For example, through subset weights, it is found that the core data in certain areas have low transmission rates and unstable signals, accounting for a large proportion. With the help of satellite positioning and geographic information systems, these areas are accurately calibrated on the map. These are the key areas where resources need to be invested in subsequent optimization measures such as equipment upgrades and signal debugging.

These data clusters reflect the operating performance of satellite Internet in different aspects and are the basic units for subsequent analysis. They cover multivariate data such as real-time fluctuation values ​​of signal strength and measured values ​​of transmission rate in various time periods. The data threshold range refers to the numerical limits set for each indicator in the network data cluster based on past experience, network standards or pre-research models.

The reasonable value range of the indicator; the core data subset refers to the key data set obtained by comparing and screening with the set data threshold range in the performance data cluster. Taking the transmission rate data cluster as an example, if the threshold is set to a minimum of 1Mbps, when the transmission rate in a certain period of time is lower than this value, these transmission rate data below the threshold are screened out to form the core data subset; the subset weight refers to the value assigned based on the importance of the network performance indicator corresponding to the core data subset to the overall network operation, as well as the proportion of the subset data in the total amount, the frequency of occurrence and other factors. For example, in a scenario focusing on user experience, the data transmission rate core subset is directly related to the smoothness of user downloads and uploads, and is given a higher weight than other indicator subsets (such as the relatively minor device temperature data subset).

[0056] Furthermore, the identification of performance data clusters in the real-time network data can be achieved through a clustering algorithm, such as K-Means clustering, which regards real-time network data as points in a multidimensional space, where each dimension represents a type of network performance data (such as signal strength, transmission rate, delay, etc.), and divides similar data points into the same cluster; the threshold setting for indicators in the network data cluster can be achieved through a classification algorithm, such as decision trees, random forests and other algorithms; the screening of core data subsets in the performance data cluster can be achieved through subset screening tools, such as Pandas, MySQL and other tools; the analysis of subset weights corresponding to the core data subsets can be achieved through weight analysis methods, such as entropy weight method, principal component analysis method, etc.; the determination of key optimization areas required for the satellite Internet can be achieved through regional determination tools, such as QGIS, ArcGIS and other tools.

[0066] The real-time usage data refers to the various parameter information reflecting the network usage that is synchronously collected at a specific time by each node (such as base station, router, terminal equipment, etc.) in the key optimization area during network operation. These data cover signal strength, transmission rate, data flow size, number of connected users, packet loss rate, etc.; the network status matrix refers to a tool for structured presentation of the network status of the key optimization area in the form of a matrix, which divides the key optimization area into multiple grid units according to certain rules (such as geographic coordinates, network hierarchy, etc.), each grid unit corresponds to an element position in the matrix, and the value of the element is integrated and quantified by the real-time usage data of each node in the corresponding area collected. For example, an urban area is divided into 10×10 grid units to construct 100×n (n is the real-time usage The network status matrix (type of parameter using data); the network unit group refers to a group formed by classifying and dividing each grid unit according to similar network characteristics or attributes on the basis of the network status matrix. For example, the grid units with signal strength between -70dBm and -80dBm and medium traffic load in the network status matrix are grouped together to form a network unit group; the network association degree refers to the degree of mutual influence and connection between different network unit groups. For example, for two adjacent network unit groups, the base station in one group often provides a large amount of data transmission services for the terminal equipment of the other group, and the signal switching between the two is frequent, then the network association degree between them is relatively high; conversely, if there is almost no data interaction and signal transmission between the two groups, the association degree is relatively low.

[0067] Furthermore, the collection of real-time usage data corresponding to each node in the network usage status can be achieved through a network management system, such as: it can be used to centrally monitor and collect actual usage data of various types of equipment (base stations, routers, terminals, etc.) in the network; the construction of the network status matrix corresponding to the key optimization interval can be achieved through a network planning tool, such as: gridding the key optimization area according to set rules (such as coverage radius, network level, etc.), automatically matching the real-time usage data of each node to the corresponding grid element position, and generating a network status matrix; the division of the network unit groups corresponding to the grid units in the network status matrix can be achieved through rule-based classification.

[0069] Among them, the signal balance value refers to a value calculated based on the optimized signal points in the key optimization area, which is used to measure the degree of balance of signal distribution in the area and reflects the discreteness of signal strength at the optimized signal points. If the signal balance value is small, it means that the signal distribution in the key optimization area is more uniform; otherwise, it means that the signal distribution difference is large.

[0070] As an embodiment of the present invention, the calculating, based on the optimized signal point, the signal equalization value corresponding to the key optimization area includes: The signal equalization value corresponding to the key optimization area is calculated using the following formula: in, Indicates the signal equalization value corresponding to the key optimization area, represents the total number of optimized signal points in the key optimization area, Indicates the number index of optimized signal points, Indicates The signal strength value corresponding to the optimized signal point is Indicates the average value of the signal strength corresponding to the optimized signal point, Indicates the standard deviation of the signal strength corresponding to the optimized signal point.

[0071] Furthermore, the optimized signal point refers to a specific location or node with a key indicative role in the key optimization area. These points are usually determined through analysis of the current network usage status. For example, in the network optimization process, locations with abnormal signal strength, large fluctuations in network performance, or poor user experience can be determined as optimized signal points; the signal strength value refers to the signal strength measured at the jth optimized signal point, which is used to describe the strength of the signal received by the optimized signal point; the average value refers to the arithmetic mean of the signal strength values ​​corresponding to all optimized signal points in the key optimization area, reflecting the overall level of signal strength in the key optimization area; the standard deviation refers to a measure of the degree of dispersion of the signal strength values ​​corresponding to all optimized signal points in the key optimization area relative to the average value, where the larger the standard deviation, the more dispersed the distribution of the signal strength values ​​between the optimized signal points; the smaller the standard deviation, the closer the signal strength value is to the average value and the more concentrated the distribution is.

[0074] Among them, the network signal index refers to a parameter generated after comprehensively considering the fluctuation level characteristics and used to measure the network signal quality in the key optimization area. For example, the network signal index may include a signal stability index, a network freeze probability index, a signal strength consistency index, etc.

[0075] As an embodiment of the present invention, the network signal index corresponding to the key optimization area is generated based on the signal balance value, including: identifying the signal value interval in which the signal balance value is located; determining the signal fluctuation standard corresponding to the signal value interval; dividing the fluctuation level corresponding to the signal balance value according to the signal fluctuation standard; performing feature extraction on the fluctuation level to obtain the fluctuation level feature; and generating the network signal index corresponding to the key optimization area based on the fluctuation level feature.

[0076] Among them, the signal value interval refers to dividing the possible value range of the signal balance value into several continuous sub-ranges. For example, the signal balance value from 0 to 100 can be divided into different intervals such as 0-20, 20-40, 40-60, 60-80, 80-100, etc.; the signal fluctuation standard refers to the rule or scale set for each signal value interval to measure the degree of signal fluctuation. For example, in the interval with a small signal balance value (such as 0-20), it can be considered that a small fluctuation change is significant; and in the interval with a large signal balance value (such as 80-100); the fluctuation level refers to further subdividing the value interval of the signal balance value into different levels according to the signal fluctuation standard. For example, within a certain signal value interval, it is divided into three levels of low fluctuation, medium fluctuation, and high fluctuation according to the signal fluctuation standard; the fluctuation level feature refers to the description of the typical attributes or characteristics of each fluctuation level. For example, a low fluctuation level may have characteristics such as smooth signal changes and stable network performance; a high fluctuation level may have characteristics such as drastic signal changes and a high risk of network freezes.

[0078] The present invention analyzes the signal fluctuation trend corresponding to the network signal indicator and identifies the fluctuation influencing factors in the signal fluctuation trend, so as to accurately grasp the dynamic changes of the network, know the advantages and disadvantages of the signal in advance, take the initiative in network maintenance and optimization troubleshooting, avoid signal deterioration affecting user use, help to reasonably plan network upgrades and resource allocation, tilt resources to weak links according to the fluctuation law, and maximize network efficiency.

[0079] The signal fluctuation trend refers to the tendency of network signal indicators (such as signal strength, stability, etc.) to change over time or other related factors (such as geographical location movement, change in the number of users, etc.). For example, the signal fluctuation trend can be that the signal strength gradually decreases during certain periods of the day, and gradually increases during other periods, showing a periodic change; or as the number of user access increases, the signal stability indicator continues to decline in a linear trend; the fluctuation influencing factors refer to various reasons that can cause fluctuations in network signal indicators. These factors are multifaceted, including natural environmental factors, such as weather conditions (heavy rain and lightning can affect signal transmission), topography (mountainous areas, high-rise buildings, etc. can cause signal obstruction or reflection); network equipment factors, such as base station power adjustment, equipment Aging or failure; user behavior factors, such as a sudden increase in the number of users leading to network congestion, and users occupying the signal by using high-bandwidth applications (such as high-definition video live broadcast); and external interference factors, such as interference from other nearby wireless signal sources, etc. Optionally, the analysis of the signal fluctuation trend corresponding to the network signal indicator can be achieved through a trend line fitting method, such as: using a fitting method such as the least squares method to fit the data points of the network signal indicator into a straight line or curve, so as to intuitively show the signal fluctuation trend; the identification of fluctuation influencing factors in the signal fluctuation trend can be achieved through a feature selection algorithm, such as: the ReliefF algorithm assigns weights according to the ability of features (influencing factors) to distinguish sample classifications (different signal fluctuation states), and features with high weights are considered to be important fluctuation influencing factors.

[0080] Furthermore, based on the fluctuation influencing factors, the present invention generates an intelligent signal monitoring report corresponding to the satellite Internet, which helps the operation and maintenance team to quickly understand the root cause of satellite signal fluctuations and accurately determine whether it is caused by environmental factors such as space radiation and orbital perturbations, or ground station equipment failures and sudden traffic peaks on the user side. It can timely adjust the monitoring direction and resource allocation to ensure signal stability.

[0081] Among them, the signal intelligent monitoring report refers to a comprehensive and dynamic document generated for satellite Internet signals based on advanced monitoring technology and intelligent algorithms. It covers all-round evaluation information of satellite signals, and records in detail the signal status in different time periods, different regions and various working conditions, including key indicators such as signal strength, stability, and transmission rate. What is particularly critical is that the report deeply analyzes various factors that affect signal fluctuations, whether it is the cosmic environmental factors such as solar storms and geomagnetic interference of satellites in space, or electromagnetic interference around ground stations, equipment aging and failure, as well as human and application scenario factors such as user-end usage habits and traffic tidal changes. Optionally, the generation of the signal intelligent monitoring report corresponding to the satellite Internet can be achieved through a report generation tool, such as: Jupyter Notebook, Tableau and other tools.

[0082] First of all, the present invention obtains the network coverage area corresponding to the satellite Internet and collects the original signal data in the network coverage area, which helps to fully understand the distribution of satellite network signals in specific areas, lays the foundation for accurately analyzing signal characteristics, and can timely detect the source of abnormal signal changes, effectively ensuring the stability and reliability of satellite Internet services in special scenarios such as remote areas, oceans, and air, and greatly improving the accuracy and efficiency of satellite network signal monitoring. At the same time, the present invention locates the interference source in the network coverage area based on the sequence dimensional characteristics combined with the satellite orbit data, ground terrain data and meteorological data corresponding to the satellite Internet, and obtains the located interference source, which can reflect the interference of factors such as the atmosphere, and then combines the sequence dimensional characteristics to accurately determine the location of the interference source, effectively shortening the time for troubleshooting interference problems, improving the stability and reliability of satellite Internet signals, and ensuring service quality and continuity. The present invention demarcates the signal in the network coverage area based on the interference intensity value. Weak areas can help network operators identify areas prone to signal problems in advance, and carry out targeted network optimization and equipment upgrades. When planning the layout of new network facilities, base stations and other equipment can be reasonably configured according to the distribution of signal weak areas to improve resource allocation efficiency. The present invention can accurately understand the actual network problems faced by users in the area, such as frequent disconnection and freeze, by querying the network usage status corresponding to the key optimization area, so that the optimization measures can directly hit the pain points. By understanding the real-time demand and peak and valley periods of data traffic, it is convenient to reasonably allocate network resources and improve resource utilization. Further, the present invention generates network signal indicators corresponding to the key optimization area based on the signal balance value, which can objectively quantify the network signal situation in the area and provide an accurate basis for evaluating network performance. These indicators can be used as an important reference for network optimization, which is convenient for targeted formulation and adjustment of optimization strategies, such as focusing on improving areas with poor signal balance, which is helpful for long-term monitoring of network quality.
