The following embodiments may be combined with each other, and some embodiments may not be repeated for the same or similar concepts or processes.
Fig. 2 is a flow chart of a method for evaluating network coverage quality according to an embodiment of the present application, and the embodiment relates to a process for evaluating network coverage quality of a target area. As shown in fig. 2, the method includes:
s201, network performance data of test points of a target area are obtained.
In the embodiment of the application, the server can firstly acquire the network performance data of the test points of the target Internet of vehicles area, then analyze the data and determine the network coverage quality evaluation value of the target area.
The embodiment of the application does not limit the area of the target area, and can be specifically set according to actual conditions. The network performance data may include location information of test points, reference signal received power, etc. The method for collecting network performance data according to the embodiment of the present application is not limited, and in some embodiments, the network performance data may be collected by a method of performing Drive Test (DT) on a target Test area.
It should be noted that, drive Test (DT) refers to a process of using a drive Test device to comprehensively measure an air interface in combination with geographic information to verify parameters of a wireless interface, and analyze, optimize and locate faults. By the drive test method, downlink signal data of wireless networks such as long term evolution technology (Long Term Evolution, LTE-V2X), global system for mobile communication (Global System for Mobile Communications, GSM) and the like can be acquired.
Table 1 is a drive test data list provided in an embodiment of the present application. As shown in table 1, each row of data contains longitude and latitude position information of a sampling point, and network performance data such as reference signal received power (Reference Signal Receiving Power, RSRP), signal-to-interference plus noise ratio (Signal to Interference plus Noise Ratio, SINR), received signal strength indication (Received Signal Strength Indication, RSSI), and the like.
TABLE 1
| Longitude/° | Latitude/° | RSRP/dBm | SINR | RSSI/dBm | Downstream Rate/Mbps |
| xxx | xxx | -76 | 6.38 | -51.94 | 546.94 |
| xxx | xxx | -76.25 | 5.5 | -51.54 | 556.31 |
S202, according to the network performance data, determining network performance characteristic points of the target area from the test points.
In this step, after acquiring the network performance data, the server may determine the network performance feature point of the target area from the test points according to the network performance data.
The network performance characteristic point may be a test point with highest network performance in a characteristic unit of the target area, and the characteristic unit of the target area may include a characteristic circle with a preset radius. In some embodiments, the server may determine a plurality of feature circle areas in the target area according to the length of a preset radius by using the position information of the test point as a circle center, and determine the network performance feature point from the test point in each feature circle according to the preset feature condition, where the distance between the circle centers of any two feature circle areas is greater than the preset radius.
Fig. 3 is a schematic diagram of a method for determining network performance feature points according to an embodiment of the present application. As shown in FIG. 3, points in the graph may be used to represent test points in a target area determined from location information. The server can arbitrarily select one test point A from the test points 1 A characteristic circle area O is determined by taking 0.8m as a radius as a circle center 1 . From the characteristic circle region O 1 Selecting one test point A from the other test points 2 Another characteristic circle area O is determined by taking 0.8m as radius as circle center 2 And then repeating the steps until all the test points are positioned in the characteristic circle area. After determining all the feature circle areas, each feature circle may contain at least one test point, and the server may select one test point with the largest RSRP value from each feature circleAll the selected test points are used as network performance characteristic points.
It should be noted that, in the embodiment of the present application, the specific length of the preset radius is not limited, and in some embodiments, the preset radius length may be determined according to the test area, the data size, the analysis requirement, and the like of the target area. For example, a length of about 0.5m to 1m may be taken as the preset radius. The preset characteristic condition may be the maximum value of the received power of the reference signal, or may be other conditions, which is not limited in the embodiment of the present application.
In other embodiments, the server may further determine an invalid feature circle based on the determined order of feature circles before determining the network performance feature points from the test points within each feature circle, and then remove the invalid feature circle. Wherein the sum of the overlapping areas of the invalid feature circle and the feature circles other than the invalid feature circle is larger than the overlapping area threshold. The server may, for example, first calculate the feature circle region O according to the determined order of the feature circle regions 1 Area overlapping with other characteristic circle region O 1 The proportion of the middle overlapping area exceeds 90%, the characteristic circle area O 1 Is determined as an invalid feature circle and the feature circle area O 1 And the test points therein are deleted. And then, repeating the steps until all the invalid feature circles and test points inside the invalid feature circles are determined and deleted.
The overlapping area threshold value may be set to 90%, or may be set to another value. The inside of the feature circle may be the boundary of the feature circle or an area within the boundary of the feature circle, which is not limited in the embodiment of the present application.
It should be noted that, since the terminal device may be temporarily stopped due to traffic or other reasons during the process of collecting data, a large number of repeated test points may be collected, thereby affecting the final data analysis accuracy. In this step, the scattered test points in the target area may be replaced by feature circle areas, and the network performance of the network performance feature points in each feature circle area is used to represent the network performance of the whole feature circle. By the method, the influence of repeated test points on the data analysis process is eliminated, and more accurate analysis results are obtained.
S203, determining a network coverage quality evaluation value of the target area according to the network performance characteristic points.
In this step, after determining the network performance feature points, the server may determine a network coverage quality evaluation value of the target area according to the network performance feature points.
In some embodiments, before determining the network coverage quality evaluation value of the target area, the server may further divide the performance data range according to the value range of RSRP, and determine a weight value corresponding to the performance data range. The embodiment of the application does not limit how to divide the performance data gears, and in some embodiments, six performance data gears can be divided according to the numerical range of the RSRP. The embodiment of the application does not limit how to determine the weight value, and can be specifically set according to the data analysis requirement.
Illustratively, table 2 is a performance data gear dividing table provided in an embodiment of the present application. As shown in Table 2, according to the value range of RSRP, 6 gears can be divided, respectively corresponding to weight value K 1 …K 6 . Wherein K is 1 +K 2 +K 3 +K 4 +K 5 ＝1，K 6 The values of (2) may be set as desired. For example, since test points with RSRP values less than-125 dBm can be considered weak coverage points, K can be determined 6 Is set to a negative value. For the RSRP value range of important attention, the corresponding weight value can be improved.
TABLE 2
| RSRP value range/dBm | Weight value | Number/number of network quality feature circles |
| x≥-90 | K 1 | N 1 |
| -90＞x≥-100 | K 2 | N 2 |
| -100＞x≥-110 | K 3 | N 3 |
| -110＞x≥-120 | K 4 | N 4 |
| -120＞x≥-125 | K 5 | N 5 |
| x<-125 | K 6 | N 6 |
The embodiment of the application does not limit the network coverage quality evaluation value of the determined target area. In some embodiments, the server may determine the number of network performance feature points in the performance data range according to the network performance data of the network performance feature points, and then determine the network coverage quality evaluation value of the target area according to the number of network performance feature points in the performance data range. Illustratively, as shown in Table 2, the server may determine eachThe number N of network quality characteristic points in RSRP value range 1 …N 6 。
The embodiment of the application does not limit how to determine the network coverage quality evaluation value of the target area according to the number of the network performance characteristic points in the performance data gear. In some embodiments, the evaluation value of the network coverage quality may be determined by a network coverage quality evaluation formula. Illustratively, the formula (1) is a network coverage quality evaluation formula provided in the embodiment of the present application.
Wherein N is 1 、N 2 …N n K represents the number of network performance characteristic points in the performance data gear 1 、K 2 …K n Representing weight values corresponding to the performance data gears, N represents the total number of network performance characteristic points, N W Representing the total number of network devices within the target area.
In some embodiments, the total number of network devices in the target area is referred to in equation (1) because the input-output ratio needs to be considered in the network analysis process. The network device may include a Road Side Unit (RSU), which is not limited in the embodiment of the present application.
In other embodiments, other network performance analysis data within the target area may also be obtained from the network performance data of the network performance feature points. Illustratively, RSRP means, SING means, etc. may be obtained, which embodiments of the present application are not limited to.
In the step, the network coverage quality evaluation value calculated by the network coverage quality evaluation formula reflects the input-output ratio of the network coverage in the target area and reflects the overall network coverage quality of the target area.
