The base station 20 is responsible for performance measurement and processing of the service area 10.

The unmanned aerial vehicle is provided with a communication terminal and can be regarded as a terminal device.

The network performance evaluation method is specifically described below according to a specific embodiment.

Example 1

Fig. 4 shows a schematic flowchart of a network performance evaluation method provided in an embodiment of the present application, as follows.

Step 401: and when the base station determines that the coverage area of the base station has intersection with the first service area, acquiring a network performance result of at least one terminal device connected with the base station.

In an alternative embodiment, the base station determines whether the coverage area of the base station intersects with the first service area according to the set location information of the first service area and the location information of the coverage area of the base station.

Optionally, the base station determines the location information of the first service area according to the configuration information of the service area configured in advance. Specifically, the user may transmit configuration information of the service area to the base station through the management system.

The configuration information of the service area comprises definition of the service area, wherein the definition of the service area comprises rule definition and irregular definition.

In an alternative embodiment, when the configuration information of the service area includes an irregular definition of the service area, the user may divide the physical area of the wireless service into a plurality of polygonal service areas according to the operator plan.

For example, as shown in fig. 5, the embodiment of the present application provides a hexagonal service area, where the location information of the service area includes longitude and latitude coordinates (lat 1, long 1), (lat 2, long 2), (lat 3, long 3), (lat 4, long 4), (lat 5, long 5), and (lat 6, long 6) of six vertices of the service area. As shown in fig. 6, the embodiment of the present application further provides a pentagon service area, where the location information of the service area includes longitude and latitude coordinates (lat 7, long 7), (lat 8, long 8), (lat 9, long 9), (lat 10, long 10) and (lat 11, long 11) of five vertices of the service area.

In another alternative embodiment, the management system may divide the physical area of the wireless service provided by the operator into a plurality of service areas equally when the configuration information of the service areas includes rule definitions of the service areas. The user can specify the size of the minimum service area, and select the effective service area from the service areas given by the management system to accept wireless service.

For example, as shown in fig. 7, another service area is also provided in the embodiment of the present application. The management system evenly divides the physical area of the wireless service provided by the operator into a plurality of service areas according to the longitude and latitude. Wherein each square represents a minimum service area and the management system numbers each service area, service area 1, service area 2, … …. In addition, the user can set the size of the minimum service area and the effective service area in the physical area through the management system.

In an alternative embodiment, after acquiring the position information of the base station, the base station determines the position information of the coverage area of the base station according to the size of the set coverage area and the acquired position information of the base station.

And the base station determines that the coverage area of the base station has intersection with the first service area according to the set position information of the first service area and the position information of the coverage area of the base station, and then obtains the network performance result of at least one terminal device connected with the base station.

Optionally, the network performance results may include, but are not limited to, at least one of: the protocol data units (protocol data unit, PDU) of the radio link control sublayer (radio link controlstructure, RLC) receive the amount of data, the total delay of traffic downlink processing, and the number of users.

In an alternative embodiment, the base station may send a measurement request to at least one terminal device and receive network performance results from the at least one terminal device. The measurement request is used for indicating the terminal equipment to perform network performance measurement.

For example, when the measurement request is a request for measuring the total downlink processing delay of the service of the terminal device, the terminal device sends the total downlink processing delay of the service measured by the terminal device to the base station as a network performance result.

In another alternative embodiment, the base station performs a performance measurement on at least one terminal device to determine a network performance result for the at least one terminal device.

For example, when the base station performs PDU received data amount measurement of the RLC layer, the base station performs measurement of PDU sessions corresponding to the terminal device 1 and the terminal device 2, determines the PDU received data amount of the RLC layer corresponding to the terminal device 1, and the PDU received data amount of the RLC layer corresponding to the terminal device 2. The base station takes the data quantity corresponding to the terminal equipment 1 as the network performance result of the terminal equipment 1, and takes the data quantity corresponding to the terminal equipment 2 as the network performance result of the terminal equipment 2.

In addition, the base station stops acquiring network performance results of the at least one terminal device when determining that there is no intersection between its coverage area and the first service area.

In the implementation, when determining that the coverage area of the base station has intersection with the first service area, the base station determines that the coverage signal of the base station enters the first service area; and starting performance measurement of the first service area, and obtaining network performance results of at least one terminal device. When the base station determines that the coverage area of the base station does not intersect with the first service area, the coverage signal of the base station is determined to completely exit the first service area; and stopping performance measurement of the first service area, i.e. stopping acquiring network performance results of the at least one terminal device.

Optionally, the measurement start time of the base station is the time when the base station determines that the coverage area of the base station has an intersection with the first service area; the measurement stop time is the time when the base station determines that its coverage area does not have an intersection with the first service area. The duration between the start time and the stop time is measured, which is the service duration of the base station passing through the first service area and is also the measured duration.

For example, as shown in fig. 8, an embodiment of the present application provides a schematic diagram of a measurement duration of network performance measurement, where the performance measurement is started when there is an intersection between a coverage area of a base station and a service area, and stopped when there is no intersection between the coverage area and the service area. The duration between the time of starting performance measurement and the time of stopping performance measurement of the base station is the measurement duration of the base station.

Step 402: the base station determines a target terminal device located in a first service area in at least one terminal device.

In an alternative embodiment, the base station obtains the location information of at least one terminal device, and determines, in the at least one terminal device, a target terminal device located in the first service area according to the location information of the set first service area and the location information of the at least one terminal device.

Alternatively, the base station may acquire the location information of at least one terminal device by:

in mode 1, a base station receives location information from at least one terminal device.

In an alternative embodiment, when the coverage area of the base station has an intersection with the first service area, the terminal device actively reports the location information to the base station after accessing the base station.

Optionally, the location information of the terminal device includes, but is not limited to: longitude and latitude information, and area identification. The region identifier is used for representing the region where the terminal equipment is located. For example, after the terminal equipment is accessed to the base station, the longitude and latitude information of the terminal equipment is actively reported to the base station.

In another alternative embodiment, the terminal device periodically reports the location information to the base station after accessing the base station. The base station periodically receives location information from the terminal device.

For example, after the terminal device accesses the base station, the location information (longitude and latitude) of the terminal device is periodically reported to the base station.

Mode 2: the base station acquires the position information of each terminal device from the network performance result of each terminal device in at least one terminal device respectively.

Optionally, after sending a measurement request to at least one terminal device, the base station performs network performance measurement according to the measurement request by at least one terminal device, so as to obtain a network measurement result. Meanwhile, after the position information of each terminal device in at least one terminal device is determined, the position information is placed in a corresponding network measurement result and is sent to a base station.

After receiving the network measurement result, the base station acquires the position information of each terminal device from the network performance result of each terminal device in at least one terminal device.

In an alternative embodiment, after determining the location information of at least one terminal device, the base station determines, according to the location information of the set first service area and the location information of at least one terminal device, a target terminal device belonging to the first service area in the at least one terminal device.

For example, when there is an intersection of the location information of the terminal device and the location information of the first service area, i.e. when the terminal device is located in the first service area, it is determined that the terminal device is a target terminal device located in the first service area.

Step 403: and the base station generates a service report of the first service area according to the network performance result of the target terminal equipment and sends the service report of the first service area to the management system. Wherein the service report of the first service area is used to characterize network performance within the first service area.

In an alternative embodiment, the first service area is a service area or a plurality of service areas. The following describes the generation of the service report of the first service area in detail based on the two cases.

Case 1: the first service area is a service area.

The base station obtains a network performance result of target terminal equipment positioned in a first service area, and generates a service report of the first service area according to the network performance result of the target terminal equipment.

In an alternative embodiment, when the target terminal device is a terminal device, the base station may use the network performance result of the target terminal device as a service report of the first service area.

In another optional implementation manner, when the target terminal device is a plurality of terminal devices, the base station combines the network performance results of the target terminal device according to the calculation mode corresponding to the network performance results to obtain the service report of the first service area.

For example, when the network performance result is the PDU received data amount of the RLC layer, the sum of the network performance results of the target terminal device is taken as the service report of the first service area. I.e. service report SUM (pdcp.vol.ul.trfpdu.rx (target terminal device 1), pdcp.vol.ul.trfpdu.rx (target terminal device 2), …, pdcp.vol.ul.trfpdu.rx (target terminal device n)). And when the network performance result is the number of users, accumulating the number of users on the network performance result of the target terminal equipment, and taking the accumulated result as a service report of the first service area.

Case 2: the first service area is a plurality of service areas.

The base station classifies the target terminal equipment according to the service areas and determines the target terminal equipment corresponding to each service area in the service areas.

For example, as shown in fig. 9, the present application provides a schematic structure of a wireless network, where an intersection exists between a coverage area of a base station and a service area 11 and a service area 12, a terminal device 41 is located in the service area 11, and a terminal device 42 and a terminal device 43 are located in the service area 12. Service area 11 and service area 12 are the first service area, and terminal device 41, terminal device 42, and terminal device 43 are target terminal devices; the base station classifies the target terminal devices according to the service areas, determines that the service area 11 corresponds to the terminal device 41, and the service area 12 corresponds to the terminal device 42 and the terminal device 43.

Optionally, the base station generates a service report of each service area according to the network performance result of the target terminal device corresponding to each service area.

For example, when the target terminal device 1 is located in the service area 1 and the target terminal device 2 and the target terminal device 3 are located in the service area 2, the base station regards the network performance result of the target terminal device 1 as a service report of the service area 1. And the base station combines the network performance results of the target terminal equipment 2 and the target terminal equipment 3 to obtain a service report of the service area 2. The process of generating the service report of the service area is the same as the process of generating the service report in the case 1, and will not be described herein.

And the base station generates a service report of the first service area according to the network performance result of the target terminal equipment and then sends the service report of the first service area to the management system.

Optionally, the base station sends the service report to the management system according to a preset measurement period. Wherein the measurement period is a short period. For example, the measurement period may be 1 minute, 30 seconds, 15 seconds, or the like.

In an alternative implementation manner, the embodiment of the application divides the measurement duration of the service area into a plurality of measurement periods through a short distance period.

The management system receives a first service report from the first base station and determines a network performance result of the first service area according to the first service report. Wherein the first service report is used to characterize network performance of a first service area, and the first service area has an intersection with a coverage area of the first base station.

In an alternative embodiment, if the management system receives only the first service report of the first base station, the management system determines a network performance result of the first service area according to the first service report.

Optionally, when the first service area is a service area, the management system directly determines a network performance result of the first service area according to the first service report.

Optionally, when the first service area is a plurality of service areas, the management area extracts a performance measurement result from the first service report according to the service areas, and determines a network performance result of each service area in the first service area according to the performance measurement result corresponding to each service area in the first service area.

In an alternative embodiment, the management system receives a second service report from a second base station. Wherein the second service report is used to characterize network performance of the first service area, and the first service area has an intersection with a coverage area of the second base station.

After receiving the second service report, the management system determines a network performance result of the first service area according to the first service report and the second service report.

In an alternative embodiment, the management system periodically receives a first service report from a first base station and periodically receives a second service report from a second base station. Correspondingly, the first base station and the second base station perform performance measurement on the first service area according to a preset measurement period.

The first base station starts performance measurement when there is an intersection of its coverage area with the first service area and stops performance measurement when there is no intersection of its coverage area with the first service area. Meanwhile, the second base station starts performance measurement when the coverage area of the second base station is intersected with the first service area, and stops performance measurement when the coverage area of the second base station is not intersected with the first service area. There may be an overlap in performance measurement time between the first base station and the second base station for the same first service area.

For example, as shown in fig. 10, at time t1, there is an intersection of the service area and the coverage area of the base station 1, and the terminal device 41 accesses the base station 1, and the terminal device 42 does not access the base station 1. At time t2, the service areas respectively intersect with the coverage areas of base station 1 and base station 2, and terminal device 41 accesses base station 2, and terminal device 42 accesses base station 1. At time t3, there is an intersection of the service area and the coverage area of base station 2, and terminal device 41 is not accessing base station 2, and terminal device 42 is accessing base station 2. At time t2, the performance measurement times of base station 1 and base station 2 overlap.

After receiving the first service report of the first base station and the second service report of the second base station, the management system determines whether the measurement period corresponding to the first service report is the same as the measurement period corresponding to the second service report.

In an alternative embodiment, if the measurement periods are the same, the management system combines the first service report and the second service report to obtain the target service report of the first service area.

For example, as shown in fig. 11, the base station 1 and the base station 2 perform performance measurement on the first service area, respectively. The measurement duration of the base station 1 is t1-t3, the measurement duration of the base station 2 is t2-t4, and the overlapping time between the measurement duration of the base station 1 and the measurement of the base station 2 is t2-t3. Wherein the time period t2-t3 comprises 3 measurement periods; that is, the management system should combine the service reports reported by the base station 1 and the base station 2 during the measurement period located in the period t2-t3 to obtain the target service report of the measurement period of the service area in the period t2-t3.

After determining the service reports needing to be combined, the management system gathers the service reports according to the summarization mode corresponding to the network performance measurement results in the service reports to obtain the target service report.

For example, when the first base station and the second base station perform performance measurement on the PDU received data amount of the RLC layer of the first service area, the first service report is a measurement result of the first base station on the PDU received data amount of the RLC layer of the first service area, and the second service report is a measurement result of the second base station on the PDU received data amount of the RLC layer of the first service area. The management system sums and summarizes the first service report and the second service report, and takes the sum and the result as a target service report of the first service area.

When the first base station and the second base station measure the performance of the total time delay of the downlink processing of the service in the first service area, the first service report is the measurement result of the total time delay of the downlink processing of the service in the first service area by the first base station, and the second service report is the measurement result of the total time delay of the downlink processing of the service in the first service area by the second base station. The management system performs average summarization on the first service report and the second service report, and takes the average summarization result as a target service report of the first service area.

When the first base station and the second base station measure the performance of the user number of the first service area, the first service report is the user number of the first base station accessed under the first service area, and when the second service report is the user number of the second base station accessed under the first service area. The management system sums and summarizes the first service report and the second service report, and takes the sum and the result as a target service report of the first service area.

In an alternative embodiment, when the first base station and the second base station perform performance measurement on the number of users in the first service area, service reports reported by the first base station and the second base station to the management system are shown in the following table 1:

table 1: service reporting for a first service area

Wherein the measurement period of the base station is 1 minute. As can be seen from table 1, for 09:26 to 09:27, both the base station 1 and the base station 2 measure the number of users in the first service area, and therefore, the number of users in the first service area in this period needs to be added up to the measurement results reported by the base station 1 and the base station 2, and the obtained measurement results of the number of users in the first service area are shown in table 2 below.

Table 2: user number measurement of first service area

Time	09:25	09:26	09:27	09:28
					Service area-user number measurement	10	10	10	10

In the method, the management system combines the service reports reported by the base stations with the same measurement period and the intersection with the same service area, so that the measurement results of the service areas obtained after combination are accurate, and the reliability and the credibility of the network performance evaluation results can be ensured.

After obtaining the target service report of the first service area, the management system determines the network performance result of the first service area according to the target service report.

Optionally, the management system performs the merging analysis on the service report based on the service area, and can completely implement the network performance evaluation based on the first service area. Wherein the management system can evaluate network performance from a service area perspective and a base station perspective.

The management system can see the time-varying performance index in a ground service area when evaluating network performance from a service area perspective.

For example, as shown in fig. 12, an embodiment of the present application provides a network performance result diagram from a service area perspective. Wherein the network performance result is the number of users. In the time period of t1-t2, the base station 1 performs performance measurement on the service area, and sends the measured number of users to the management system. In the time period of t2-t3, the base station 2 performs performance measurement on the service area, and transmits the measured number of users to the management system. In the time period of t3-t4, the base station 3 performs performance measurement on the service area, and transmits the measured number of users to the management system. In the time period of t4-t5, the base station 4 performs performance measurement on the service area, and sends the measured number of users to the management system. From what is shown in fig. 12, it can be seen that the number of users in one service area varies, and the service area is served by different base stations at different times.

As another example, as shown in fig. 13, another network performance result diagram from a service area perspective is also provided in the embodiments of the present application. Wherein the network performance result is the number of users. In the time period of 09:25-09:28, the number of users in the service area is 10, and the index of the number of users accessed in the service area is stable.

When the management system evaluates the network performance from the perspective of the base station, the change condition of the performance index can be seen when the base station passes through different service areas.

For example, as shown in fig. 14, the embodiment of the present application provides a network performance result diagram from the base station perspective. Wherein the network performance result is the number of users. In the period of t1-t2, the base station 1 passes through the service area 1 and performs performance measurement on the service area 1. In the period of t2-t3, the base station 1 passes through the service area 2 and performs performance measurement on the service area 2. In the period of t3-t4, the base station 1 passes through the service area 3 and performs performance measurement on the service area 3. In the period of t4-t5, the base station 1 passes through the service area 4 and performs performance measurement on the service area 4. In the period of t5-t6, the base station 1 passes through the service area 5 and performs performance measurement on the service area 5. In the period of t6-t7, the base station 1 passes through the service area 6 and performs performance measurement on the service area 6. Based on the content shown in fig. 14, it can be seen from the base station perspective that when a satellite base station passes through the service areas 1 to 6, the number of access users on the satellite base station changes.

In the above embodiment 1, when determining that the coverage area of the base station has an intersection with the first service area, the base station performs network performance measurement on the first service area, obtains a network performance result of at least one terminal device connected to the base station, and can control the time for performing performance detection on the first service area; the base station determines target terminal equipment positioned in a first service area in at least one terminal equipment, generates a service report of the first service area according to a network performance result of the target terminal equipment, sends the service report of the first service area to a management system, and completes performance detection of the first service area, thereby realizing network performance measurement of a wireless network deploying the movable base station.

Step 1505: and the base station generates a service report of the first service area according to the network performance result of the target terminal equipment.

Step 1506: and the base station sends a service report to the management system according to a preset measurement period.

Step 1507: the base station stops acquiring the network performance result of the at least one terminal device.

In the embodiment shown in fig. 15, when the base station determines that there is an intersection between the first service area and the coverage area of the base station, performance measurement is performed on the first service area, and network performance results of at least one terminal device connected to the base station are obtained. Then, the base station determines a target terminal device located in the first service area from at least one terminal device, and generates a service report of the first service area according to the network performance result of the target terminal device, thereby completing the network performance measurement of the wireless network deploying the movable base station. And when the base station determines that the coverage area of the base station does not intersect with the first service area, the base station stops performance detection of the first service area, so that the time for performance detection of the service area can be controlled.

Based on the network performance evaluation scheme described in the above embodiment, the embodiment of the present application further provides a network performance evaluation method. The interactive flow of the method is described below with reference to fig. 16.

Wherein the configuration information includes a rule definition or an irregular definition of the service area.

Step 1602: the first base station determines that an intersection exists between a coverage area of the first base station and the first service area.

In implementation, the first base station determines whether the coverage area has an intersection with the first service area according to the set position information of the first service area.

Step 1603: the first base station transmits a first service report of the first service area to the management system according to the measurement period. The management system periodically receives a first service report from the first base station. Wherein the first service report is used to characterize network performance of the first service area.

The process of determining the first service report of the first service area by the first base station is the same as the process of determining the service report of the first service area in fig. 15, and will not be described herein.

Step 1604: the second base station determines that there is an intersection of the coverage area of the second base station with the first service area.
