As shown in fig. 3, fig. 3 is a schematic flowchart of a method for testing network coverage performance according to an embodiment of the present application. The embodiment of the present application may be applied to the acquisition device in the network coverage performance test system shown in fig. 1, and includes: S301-S302.

S301, the acquisition equipment acquires a plurality of test data of the area to be tested according to a plurality of preset acquisition routes.

Wherein the acquisition device may be the acquisition device 104 in fig. 1, and the area to be tested may be an area served by a plurality of base stations. Such as the area that may serve base station 101, base station 102, base station 103, and base station 104 in fig. 1.

Specifically, when testing the network performance of the ground public network, the vehicle, the test terminal, the test software and the like can be used for collecting data on the ground and analyzing the data to determine the network performance. And when the performance of the network in the air coverage aspect is tested, the test data of the network air coverage can be acquired by means of acquisition equipment comprising the networked unmanned aerial vehicle.

The plurality of acquisition routes are predetermined by the flight altitude and the horizontal flight route according to actual conditions, and can also be comprehensively determined by combining other factors according to specific conditions in actual tests, which is not limited in the present application.

Alternatively, the flying height may be divided according to manual experience, for example, heights of 50m, 100m, 150m, 200m, 250m, 300m, and the like.

It should be noted that obstacles in the low-altitude environment of the area to be tested should be taken into account when determining the flight altitude.

Alternatively, the horizontal flight path may be a grid-type zigzag path, or may be other paths that can traverse the area to be tested, which is not limited in this application.

When the horizontal flight path is a grid-type zigzag path, the grid granularity of the horizontal flight path can be determined according to the number and the density of the base stations in the area to be tested. If the number of the base stations in the area to be tested is large and dense, the grid granularity of the horizontal flight line can be set to be dense. Correspondingly, if the number of the base stations in the area to be tested is small and sparse, the grid granularity of the horizontal flight path can be correspondingly adjusted to be sparse.

In practical applications, the flying height and the horizontal flying route need to cover the area to be tested as completely as possible, so as to obtain complete test data.

Optionally, the flying speed of the internet unmanned aerial vehicle is generally set to be 20-50Km/h, and the flying speed can be adjusted according to actual conditions, which is not limited in the application.

Through the preset collection routes, the collection equipment can collect a plurality of test data of the area to be tested.

Optionally, in the actual testing process, other acquisition parameters necessary for data analysis may also be acquired, which is not limited in the present application.

The uplink data comprises one or more of the following: uplink Reference Signal Received Power (RSRP), uplink signal to interference plus noise ratio (SINR), uplink packet data convergence layer (PDCP)/radio link control sublayer (RLC)/medium access control layer (MAC)/physical layer (PHY) layer rate, uplink Modulation and Coding Scheme (MCS), number of Resource Blocks (RBs) scheduled per Transmission Time Interval (TTI), uplink transmission mode, RANK of uplink channel matrix (RANK), uplink block error rate (BLER).

The downstream data includes one or more of: downlink RSRP, downlink SINR, layer rate of a downlink PDCP/RLC/MAC/PHY layer, downlink MCS, the number of RBs scheduled by each downlink TTI, a downlink transmission mode, downlink RANK, downlink BLER, downlink transmission power collected by a base station providing service for an area to be tested, and Synchronization Signaling Block (SSB) power configuration.

Optionally, when the uplink data and the downlink data are collected, the collecting device may fly twice on a preset collecting line, so as to respectively collect the uplink data and the downlink data. That is, only uplink data is collected during the first flight, and only downlink data is collected during the second flight. Or, only downlink data is collected during the first flight, and only uplink data is collected during the second flight.

The acquisition equipment can also fly once on a preset acquisition route, so that uplink data and downlink data are acquired simultaneously. That is, uplink data and downlink data are simultaneously acquired during one flight.

The preset acquisition equipment comprises an internet unmanned aerial vehicle. When the networked unmanned aerial vehicle collects test data, the networked unmanned aerial vehicle can fly along a preset collection route (for example, a horizontal flight route with a flight height of 50m, which is a shape like the Chinese character 'zhi' and the like) from a test starting point, and simultaneously collects test data required by testing the coverage performance of a network: and acquiring parameters, uplink data and downlink data until the test terminal point is reached by flying, and then returning to the initial point to finish the acquisition of the test data. The data that networking unmanned aerial vehicle gathered in same collection route is a test data.

Then, the acquisition route of the networked drone may be adjusted (e.g., the flying height is adjusted from 50m to 100m, and the horizontal flying route is kept unchanged), and the next test data is acquired according to the above method for acquiring data. Subsequently, different flying heights can be adjusted, and next test data is acquired according to the data acquisition method, so that a plurality of test data of the area to be tested are obtained.

For example, referring to fig. 1, as shown in fig. 4, the networked drone in the acquisition device 105 may acquire 6 test data of the area to be tested at 6 flying heights (50m, 100m, 150m, 200m, 250m, 300 m).

S302, the acquisition equipment determines the network coverage performance of the area to be tested according to the plurality of test data.

Specifically, after a plurality of test data are collected, the collection equipment can quickly and efficiently determine the network coverage performance of the area to be tested according to the test data of a plurality of dimensions, and a foundation is laid for network planning of the area to be tested.

The technical scheme provided by the embodiment at least has the following beneficial effects: it can be known from S301 to S302 that, the above embodiment provides a method for testing network coverage performance, where an acquisition device acquires a plurality of test data of an area to be tested according to a plurality of preset acquisition routes, and determines the network coverage performance of the area to be tested according to the plurality of test data. Because a plurality of test data correspond to a plurality of collection routes one-to-one, and the test data include: the method comprises the steps of collecting parameters, uplink data and downlink data, and therefore, the method can obtain a plurality of test data from a plurality of dimensions such as the number of collected routes (a plurality of collected routes), the number of collected parameters (a plurality of collected parameters) and the type of the test data (the uplink data and the downlink data), so that the influence of factors such as frequent switching between base stations, interference of the uplink data and the downlink data, interference of users in the air space and the like in an area to be tested can be avoided in the process of testing the network coverage performance, and the network coverage performance in the area to be tested can be comprehensively tested.

In an implementation manner, referring to fig. 3, as shown in fig. 5, the acquiring device acquires a plurality of test data of an area to be tested according to a plurality of preset acquiring routes, including:

s501, the acquisition equipment executes acquisition operation on each acquisition route in the plurality of acquisition routes to obtain a plurality of test data.

Wherein the collecting operation comprises:

on one acquisition route, the acquisition equipment sends uplink service requests and downlink service requests to a plurality of base stations which provide services for an area to be tested, receives uplink data and downlink data sent by the plurality of base stations and acquires an acquisition parameter on one acquisition route; determining a test data collected on a collection line comprises: one acquisition parameter, and uplink data and downlink data sent by a plurality of base stations.

Optionally, when the acquisition device flies according to the preset acquisition route in the area to be tested, the acquisition device may separately send the uplink service request or the downlink service request, and record the test data, after the acquisition of one acquisition data is completed, the acquisition device flies according to the same preset acquisition route, and then sends the downlink service request or the uplink service request, and records the test data. The acquisition device can also simultaneously initiate uplink service requests and downlink service requests and record test data.

Illustratively, taking the networked unmanned aerial vehicle as the acquisition device, the acquisition route is determined to be 6 flight altitudes, including: 50m, 100m, 150m, 200m, 250m, 300 m. Firstly, the networked unmanned aerial vehicle takes off at the acquisition starting point of the area to be tested, continuously sends an uplink service request, flies along a horizontal route in the shape of a Chinese character 'zhi' at the flying height of 50m, and simultaneously acquires test data. And after the networked unmanned aerial vehicle returns to the acquisition starting point, the acquisition of the test data is completed. And secondly, the networked unmanned aerial vehicle continuously sends downlink service requests and collects test data in the area to be tested along the same collection route. And then, acquiring test data by the networked unmanned aerial vehicle in other determined acquisition routes by using the same acquisition operation at the flying heights of 100m, 150m, 200m, 250m and 300m respectively.

The technical scheme provided by the embodiment at least has the following beneficial effects: as can be seen from S501, on one hand, the acquisition device performs the acquisition operation on each of the plurality of acquisition routes, and the internet-connected unmanned aerial vehicle performs the acquisition operation at a plurality of different heights, so as to obtain a plurality of test data corresponding to different acquisition routes, so that the network coverage performance determined subsequently according to the test data includes network coverage performances at different heights, and further the test result covers the test area more comprehensively; on the other hand, the acquisition equipment acquires uplink data and downlink data on each acquisition route, so that the acquired test data corresponding to each acquisition route simultaneously contains the uplink data and the downlink data, and the network coverage performance in different aspects can be tested. Therefore, more comprehensive test data can be provided for the subsequent determination of the network coverage performance, so that the accuracy of the determined network coverage performance is improved.

In an implementation manner, referring to fig. 3 and as shown in fig. 6, the determining, by the acquisition device, the network coverage performance of the area to be tested according to the plurality of test data includes:

s601, acquiring a plurality of uplink data and a plurality of downlink data which are in one-to-one correspondence with a plurality of acquisition routes by the acquisition equipment.

Specifically, the acquired uplink data and the acquired downlink data may be different under different acquisition parameters, so that, in order to eliminate interference of changes of the uplink data and the downlink data caused by different acquisition parameters on data analysis, the acquisition device may use the uplink data and the downlink data acquired under the current acquisition parameter as a set of test data after the acquisition of the test data of each acquisition route is completed in the area to be tested, so as to determine the network coverage performance of the area to be tested under the acquisition parameter according to the set of test data.

S602, the acquisition equipment determines performance indexes under a plurality of acquisition parameters according to the plurality of uplink data and the plurality of downlink data.

Optionally, the indicator of the network coverage performance includes one or more of the following: the system comprises an accessibility index, a retentivity index, a perception index, a service load index, a service coverage index, a network interference index and the like.

Wherein each type of metric may measure an aspect of network coverage performance.

Illustratively, the accessibility index is an important index system reflecting the coverage performance of the regional network to be tested, and comprises an access success index and an access delay index.

The retentivity index includes a drop rate, a handover type index, and the like. The switching refers to the collection equipment in a mobile state, from one place to another place, in order to ensure that the service of the collection equipment is not interrupted in the mobile state, the collection equipment needs to be switched from one cell to another cell, and the switching indexes are mainly used for measuring the switching success rate and the switching speed.

In the embodiment of the application, the following indexes are selected for measuring the network coverage performance of the area to be tested.

For the uplink test data, the uplink RSRP, the uplink SINR, the uplink rate, the uplink MCS, and the uplink Channel Quality Indicator (CQI) under different acquisition parameters may be compared, the uplink switching success rate and the uplink switching delay of the user plane and the control plane may be analyzed, the uplink drop frequency may be counted, the uplink drop rate may be calculated, and the uplink access failure frequency may be counted.

For downlink test data, the downlink RSRP, the downlink SINR, the downlink rate, the downlink MCS and the downlink CQI under different acquisition parameters can be compared, the downlink switching success rate and the downlink switching time delay of a user plane and a control plane are analyzed, the downlink drop frequency is counted, the downlink drop frequency is calculated, and the downlink access failure frequency is counted.

RSRP is a key parameter for measuring the network signal coverage strength of the area to be tested. RSRP has 6 intensity levels.

When the RSRP > -65dBm exists, the RSRP coverage strength is level 1, and the network coverage performance of the area to be tested is very good.

When-75 dBm < RSRP ≦ 65dBm, the RSRP coverage strength is level 2, representing network coverage performance second only to level 1. In this case, the user may initiate various services outdoors in the area to be tested, wherein the service rate of the data service may reach a high rate, and may also initiate various services indoors in the area to be tested, but the service rate of the data service may only reach a medium rate.

When-85 dBm < RSRP ≦ 75dBm, the RSRP coverage strength is level 3, representing network coverage performance inferior to level 1 and level 2. In this case, the user may initiate various services outdoors in the area to be tested, wherein the service rate of the data service may reach a medium rate, and may also initiate various services indoors in the area to be tested, but the service rate of the data service may only reach a low rate.

When-95 dBm < RSRP ≦ 85dBm, the RSRP coverage strength is rank 4, representing network coverage performance inferior to rank 1, rank 2, and rank 3. In this case, the user may initiate various services outdoors in the area to be tested, wherein the service rate of the data service can only reach a low rate, but only the voice service can be initiated indoors in the area to be tested, and the call success rate of the voice service is low.

When-105 dBm < RSRP ≦ 95dBm, the RSRP coverage strength is level 5, representing network coverage performance inferior to level 1, level 2, level 3, and level 4. In this case, the user can only initiate the voice service outdoors in the area to be tested, and the call success rate of the voice service is low, and the service cannot be initiated indoors in the area to be tested.

When RSRP ≦ 105dBm, the RSRP coverage strength is level 6, representing network coverage performance inferior to level 1, level 2, level 3, level 4, and level 5. In this case, traffic cannot be basically initiated both outdoors and indoors of the area to be tested.

SINR is used to represent the ratio of the strength of a received desired signal to the strength of a received interfering signal (noise and interference). If the SINR of the area to be tested is low, the fact that the area to be tested is represented to be in the area to be tested is that the noise and the interference received by the acquisition equipment are large, the quality of network signals is poor, and the network coverage performance is poor.

Correspondingly, if the SINR of the area to be tested is high, the area to be tested represents that the area to be tested has low noise and interference received by the acquisition equipment, good network signal quality and good network coverage performance.

Generally, according to the quality level of the network coverage performance, the specific ranges of the noise and the interference received by the acquisition device from high to low are as follows: SINR is more than 25dB, SINR is more than or equal to 16dB and less than or equal to 25dB, SINR is more than or equal to 11dB and less than or equal to 15dB, SINR is more than or equal to 3dB and less than or equal to 10dB, and SINR is less than 3 dB.

The uplink rate refers to a data transmission rate when the acquisition device sends an uplink service to the base station. The downlink rate refers to a data transmission rate when the base station sends downlink service to the acquisition device, and for different network systems, evaluation indexes of the uplink rate and the downlink rate are different. Generally speaking, the larger the values of the uplink rate and the downlink rate, the better the network coverage performance is represented.

And the configuration of the network rate in the area to be tested is realized through the MCS index value. The MCS takes the concerned factors influencing the network rate in the area to be tested as the column of the table, and the MCS index as the row to form a rate table. Therefore, each MCS index actually corresponds to a transmission rate under a set of parameters. The average value of the uplink MCS is more than or equal to 18, and the average value of the downlink MCS is more than or equal to 15, which represents that the network coverage performance is better.

The CQI represents the quality of the current channel, corresponds to the signal-to-noise ratio of the channel and ranges from 0 to 31. When the CQI value is 0, the channel quality is the worst; when the CQI takes the value of 31, the channel quality is the best. The value is generally 12 to 24.

The main purpose of switching is to ensure the continuity of uplink service and downlink service in the area to be tested and to improve the service quality. The handover success rate is divided into a handover success rate with handover preparation and a handover success rate without handover preparation. Wherein, the switching success rate containing switching preparation is switching success times/switching request times 100%; handover preparation not contained handover success rate is 100% of handover success times/handover attempt times. When the handover success rate is more than 95%, the network coverage performance is better.

The disconnection rate is used for measuring the probability that the acquisition equipment abnormally loses contact with the network after the acquisition equipment successfully accesses the network provided with the service by the base station. The calculation formula of the disconnection rate is as follows: and the disconnection rate is the disconnection times/connection establishment success times, and when the disconnection rate is less than or equal to 1%, the network coverage performance is better.

A smaller number of access failures represents better network coverage performance.

Optionally, other indexes for measuring the network coverage performance may also be adopted, which is not limited in the present application.

The technical scheme provided by the embodiment at least has the following beneficial effects: from S601-S602, on one hand, by making the acquisition parameters and the test data correspond to each other, the error of the network coverage performance result caused by different acquisition parameters can be reduced.

Therefore, the determined network coverage performance can be more scientific and convincing.
