The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 2 is a schematic flow chart of a method for evaluating network coverage quality according to an embodiment of the present application, where 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 the test point of the target area is obtained.
In this embodiment of the application, the server may first obtain network performance data of the test point in the target vehicle networking area, and then analyze the data to determine a network coverage quality evaluation value in the target area.
The area of the target region is not limited in the embodiment of the application, and can be specifically set according to actual conditions. The network performance data may include location information of the test points, reference signal received power, and the like. The method for acquiring the network performance data is not limited in the embodiments of the present application, and in some embodiments, the network performance data may be acquired by performing a Drive Test (DT) method on a target Test area.
It should be noted that Drive Test (DT) refers to a process of using a drive Test device to perform comprehensive measurement on an air interface in combination with geographic information, so as to verify parameters of the air interface, and analyze, optimize and locate a fault. By the drive test method, downlink signal data of wireless networks such as Long Term Evolution (LTE-V2X) and Global System for Mobile Communications (GSM) can be collected.

As shown in table 1, each line of data includes longitude and latitude position information of the sampling point, Reference Signal Receiving Power (RSRP), Signal to Interference plus Noise Ratio (SINR), Received Signal Strength Indicator (RSSI), and other network performance data.
TABLE 1
| Longitude/degree | Latitude/degree | RSRP/dBm | SINR | RSSI/dBm | Downlink 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 the network performance data is obtained, the server may determine the network performance characteristic 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 the 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 characteristic circle regions in the target region by using the position information of the test point as a circle center according to the length of the preset radius, where the distance between the circle centers of any two characteristic circle regions is greater than the preset radius, and then determine the network performance characteristic point from the test point in each characteristic circle according to the preset characteristic condition.
Fig. 3 is a schematic diagram illustrating a method for determining a network performance characteristic point according to an embodiment of the present application. As shown in FIG. 3, points in the graph may be used to represent target areas determined from location informationTest points in a domain. The server can randomly select a test point A from the test points1A characteristic circle area O is determined by taking 0.8m as the radius as the center of a circle1. Then from the characteristic circle region O1Arbitrarily selecting a test point A from other test points2Using 0.8m as radius to define another characteristic circle region O2And then, continuously repeating the steps until all the test points are positioned in the characteristic circle region. After determining all the feature circle areas, each feature circle may contain at least one test point therein, and the server may select one test point with the largest RSRP value from each feature circle, and then use all the selected test points as network performance feature points.
It should be noted that, in the embodiment of the present application, a specific length of the preset radius is not limited, and in some embodiments, the length of the preset radius may be determined according to a test area, a data size, an analysis requirement, and the like of the target region. Illustratively, a length of about 0.5m to 1m may be taken as the preset radius. The preset characteristic condition may be that the value of the reference signal received power is maximum, or may be other conditions, which is not limited in this embodiment of the present application.
In other embodiments, before determining the network performance feature points from the test points in each feature circle, the server may further determine invalid feature circles according to the determination sequence of the feature circles, and then remove the invalid feature circles. And the sum of the overlapping areas of the invalid characteristic circle and the characteristic circles except the invalid characteristic circle is larger than the overlapping area threshold value. For example, the server may first calculate the characteristic circle region O according to the determined order of the characteristic circle regions1Area of overlap with other characteristic circle area, if characteristic circle area O1When the ratio of the center-to-center overlapping area exceeds 90%, the characteristic circle region O is formed1Determining as invalid characteristic circle, and defining characteristic circle region O1And deleting the test points inside the test points. And then, continuously repeating the steps until all invalid feature circles and test points inside the invalid feature circles are determined and deleted.
It should be noted that the overlap area threshold may be set to 90%, or may be set to other values. The inside of the feature circle may be a boundary of the feature circle and a region within the boundary, or a region within the boundary of the feature circle, which is not limited in the embodiment of the present application.
It should be noted that, in the process of acquiring data, the terminal device may stop temporarily due to traffic or the like, so that a large number of repeated test points are acquired, thereby affecting the final data analysis accuracy. In this step, the scattered test points in the target area may be replaced with the characteristic circle areas, and the network performance of the network performance characteristic points in each characteristic circle area may represent the network performance of the entire characteristic circle. By the method, the influence of repeated test points on the data analysis process is eliminated, and a more accurate analysis result is 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 characteristic points, the server may determine the network coverage quality evaluation value of the target area according to the network performance characteristic points.
In some embodiments, before determining the network coverage quality evaluation value of the target area, the server may further divide the performance data gear according to the value range of RSRP, and determine a weight value corresponding to the performance data gear. The embodiment of the application is not limited to how to divide the performance data gear, and in some embodiments, six performance data gears may be divided according to the numerical range of RSRP. The embodiment of the application is also not limited to how to determine the weight value, and the weight value can be specifically set according to the data analysis requirement.
Illustratively, table 2 is a performance data gear division table provided in the embodiments of the present application. As shown in table 2, according to the range of RSRP, 6 gears can be divided, and each gear corresponds to a weight value K1…K6. Wherein, K1+K2+K3+K4+K5＝1，K6The value of (c) can be set as desired. For example, K may be assigned since test points with RSRP values less than-125 dBm may be considered weak coverage points6Set to a negative value. To pairThe corresponding weight value can be improved by focusing on the value range of the important concerned RSRP.
TABLE 2
| RSRP value range/dBm | Weight value | Number/number of network quality feature circles |
| x≥-90 | K1 | N1 |
| -90＞x≥-100 | K2 | N2 |
| -100＞x≥-110 | K3 | N3 |
| -110＞x≥-120 | K4 | N4 |
| -120＞x≥-125 | K5 | N5 |
| x<-125 | K6 | N6 |
The embodiment of the present application does not limit the network coverage quality evaluation value for determining the target area. In some embodiments, the server may determine the number of network performance feature points in the performance data gear according to the network performance data of the network performance feature points, and then determine the network coverage quality assessment value of the target area according to the number of network performance feature points in the performance data gear. For example, as shown in table 2, the server may determine the number N of network quality feature points in each RSRP value range1…N6。
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 can be determined through a network coverage quality evaluation formula. Illustratively, the formula (1) is a network coverage quality assessment formula provided in the embodiments of the present application.
Wherein N is1、N2…NnNumber of network performance characteristic points, K, in the gear representing the performance data1、K2…KnRepresenting the weight value corresponding to the performance data gear, N representing the total number of the network performance characteristic points, NWRepresenting 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 formula (1) because the network analysis process needs to take into account the input-output ratio. The network device may include a Road Side Unit (RSU), and the like, which is not limited in this embodiment.
In other embodiments, other network performance analysis data in the target area may also be obtained through the network performance data of the network performance feature points. Illustratively, RSRP mean values, SING mean values, etc. may be obtained, which is not limited in the embodiments of the present application.
In this 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.
