The wireless local area network (Wireless Local Area Network, abbreviated as WLAN) refers to a network system that uses wireless communication technology to interconnect computer devices to form a network system that can communicate with each other and realize resource sharing. The wireless local area network is essentially characterized in that a computer is not connected with a network by using a communication cable, but is connected in a wireless mode, so that the construction of the network and the movement of a terminal are more flexible, for example, a Station (STA) in Wi-Fi is connected with an Access Point (AP) in a wireless mode, and data interaction is performed in a wireless communication mode. Because the wireless communication is adopted, the problem of air interface interference is very easy to occur, and application programs for analyzing interference in Wi-Fi air interface environments appear in the related technology, wherein the application programs can be operated on a smart phone or in a computer.
In general, an application program for analyzing interference in a Wi-Fi air interface environment scans Wi-Fi full-band (2.4 GHz and 5 GHz) or partial-band using an API (Application Programming Interface, application program interface) interface of an operating system, and monitors and analyzes Wi-Fi Beacon frames sent by an AP device, so that information of other AP devices (AP devices connected to non-monitoring devices) running on the same space in the same period, such as SSID (Service Set Identifier ), working channel, bandwidth (e.g., 20/40/80 MHz), supported Wi-Fi standards (b/g/n, ac, ax), signal strength, and the number of STAs connected to the AP device, etc., can be obtained. Some application programs for analysis can correlate the data with the AP connected with the data, analyze the number of devices and interference intensity of the same-frequency, adjacent-frequency and overlapping-frequency interference, and give scores; some applications that perform analysis perform ping (Packet Internet Groper, internet packet explorer) tests on servers of commonly used websites (e.g., video websites, shopping websites, etc.) using the Wi-Fi network that is currently connected, thereby analyzing the congestion level in the Wi-Fi air interface environment.
The scheme has good effect on interference analysis in Wi-Fi air interface environment, the intelligent equipment can change the connected AP again according to the channel surrounding interference condition of the connected AP so as to avoid an interference source, or select the AP with lower load to be accessed again, but the mode is convenient for selecting a better network, and has no great help on evaluating network efficiency and developing Wi-Fi technology by constructing the interference environment in a laboratory or in different scenes in the future.
Meanwhile, a technical scheme of constructing an interference environment through attenuation and blocking of an AP signal is also proposed in the related art, and an interference source comprises signal shielding between the AP and the STA caused by blocking of a building (such as a wall) and furniture (such as a table, a sofa and the like) besides other Wi-Fi signals. In order to restore the interference environment, physical signal attenuation (such as an attenuator is externally added on an antenna of the AP) or path attenuation (such as one or two walls are added between the AP and the STA in a test environment, or the distance between the AP and the STA is prolonged) needs to be constructed at the AP side, so that the effect of simulating the interference environment is achieved. Another way to simulate interference is to send TCP (Transmission Control Protocol )/UDP (User Datagram Protocol, user packet protocol) packets over the air by other Wi-Fi devices on the operating band of the AP to which the test device is connected, or directly send non-Wi-Fi signals using a signal generator to construct the interference signal.
However, the technical scheme of constructing the interference environment through attenuation and blocking of the AP signal can achieve the effect of generating interference to a certain extent on Wi-Fi equipment to be detected, but the interference is only dependent on different interference degrees in a self-defining manner, and cannot realize refined and accurate control. If three different interference degrees are set, the strong interference uses three groups of Wi-Fi devices to send TCP or UDP data streams, the middle interference uses two groups of Wi-Fi devices to send TCP or UDP data streams, and the weak interference uses one group of Wi-Fi devices to send TCP or UDP data streams. Of course, different interference intensity configurations on some objective indexes (such as Wi-Fi channel utilization rate, signal to noise ratio and the like) can be expressed as increasing or decreasing along with the interference intensity, so as to reflect a specific interference degree, however, the interference degree cannot be compared with an actual application scene (such as an interference environment in a home scene and an interference environment in an office), and the interference environment in the actual application scene cannot be accurately restored, so that the application effect is limited.
Based on the above, the embodiment of the application provides a complete Wi-Fi interference scene recording, analyzing and simulating and restoring technical scheme. According to the method, the interference degree of the recorded original scene can be simulated offline in a laboratory environment according to the numerical value of the recorded and analyzed characteristic variable, different combinations of the same-frequency signal, the adjacent-frequency signal, the overlapping-frequency signal and the non-Wi-Fi interference signal are sent out by a plurality of devices, the interference scene is restored, and further the development tasks of Wi-Fi device performance evaluation and performance tuning technology under the same interference scene are achieved.
Specifically, in an application scenario of the present application, as shown in fig. 1, in an indoor environment, there are different degrees of interference in the indoor environment due to the presence of furniture blocking and interference of other Wi-Fi devices (such as routers). In order to measure specific interference situations, the test device 102 may be connected to a designated router 101 (i.e. an access point device), and then measures interference index information generated by an interference source in an indoor environment for the test device 102 to obtain an index measurement result, and further generates a statistics result of index feature values according to the index measurement result, where the statistics result of the index feature values includes an interference signal feature value statistics result and an experience index feature value statistics result.
The foregoing indicator measurement results may include an interference signal measurement result and an experience indicator measurement result, where the interference signal measurement result may include at least one of the following information: the number of wireless local area network devices (e.g., wi-Fi devices) that interfere with the test device 102, the signal transmission strength of the wireless local area network devices that interfere with the test device 102, the channel utilization of the wireless local area network channel in which the test device 102 is located, the signal to noise ratio of the wireless local area network channel in which the test device 102 is located, the error vector magnitude (Error Vector Magnitude, abbreviated EVM) of the wireless local area network channel in which the test device 102 is located, the packet error rate (Packet Error Rate, abbreviated PER) of the wireless local area network to which the test device 102 is connected, the wireless local area network data stream traffic that interferes with the test device 102, the signal strength of the non-wireless local area network that interferes with the test device 102, and the bandwidth of the non-wireless local area network that interferes with the test device 102.
Alternatively, the interference signal characteristic value statistics may include characteristic statistics of the wireless local area network interference signal, and the characteristic statistics may be, for example, channel utilization, signal-to-noise ratio, error vector magnitude, and the like. The interference signal characteristic value statistics may include characteristic measurements of wireless local area network interference signals, which may include: the number of interfering wlan devices, the maximum signal strength of the interfering wlan devices, the bandwidth most used in the interfering wlan devices, the total traffic used by the interfering wlan devices.
The aforementioned wlan interference signals may be co-channel interference signals, adjacent channel interference signals and overlapping channel interference signals of the Wi-Fi network to which the test device 102 is connected.
Optionally, the interference signal characteristic value statistics result further includes a characteristic statistics value of a non-wireless local area network interference signal, where the characteristic statistics value of the non-wireless local area network interference signal includes: the bandwidth distribution and the corresponding signal intensity of the non-wireless local area network interference signals in each set time interval. The non-wireless local area network interference signal may be, for example, an interference signal of a mobile communication network (e.g., a 4G/5G network).
After the interference signal characteristic value statistical result and the experience index characteristic value statistical result are obtained, a simulation environment corresponding to the indoor environment can be constructed according to the interference signal characteristic value contained in the interference signal characteristic value statistical result, so that the experience index measured value in the simulation environment is matched with the experience index characteristic value statistical result. After constructing a simulation environment corresponding to the indoor environment, development of wireless local area network technology and performance evaluation of wireless local area network equipment can be performed in the constructed simulation environment.
In addition to the indoor environment, as shown in fig. 2, various interferences exist in the conference room environment, so that after the test device 201 is connected to a designated router (i.e., an access point device), interference index information generated by an interference source in the conference room environment for the test device 201 can be measured, an index measurement result is obtained, and further, a statistics result of index feature values including an interference signal feature value statistics result and an experience index feature value statistics result is generated according to the index measurement result. After the interference signal characteristic value statistical result and the experience index characteristic value statistical result are obtained, a simulation environment corresponding to the conference room environment can be constructed according to the interference signal characteristic value contained in the interference signal characteristic value statistical result, so that the experience index measured value in the simulation environment is matched with the experience index characteristic value statistical result. After constructing a simulation environment corresponding to the conference room environment, development of wireless local area network technology and performance evaluation of wireless local area network equipment can be performed in the constructed simulation environment.
As shown in fig. 3, various interferences exist in the office environment, so after the test device 301 is connected to a designated router (i.e., an access point device), interference index information generated by an interference source in the office environment for the test device 301 is measured, an index measurement result is obtained, and a statistics result of index feature values including an interference signal feature value statistics result and an experience index feature value statistics result is generated according to the index measurement result. After the interference signal characteristic value statistical result and the experience index characteristic value statistical result are obtained, a simulation environment corresponding to the office environment can be constructed according to the interference signal characteristic value contained in the interference signal characteristic value statistical result, so that the experience index measured value in the simulation environment is matched with the experience index characteristic value statistical result. After constructing a simulation environment corresponding to the office environment, development of wireless local area network technology and performance evaluation of wireless local area network equipment can be performed in the constructed simulation environment.
Of course, for other environments, such as subway station environments, high-speed mobile environments (such as environments in vehicles) and the like, measurement can be performed through the technical scheme of the embodiment of the application, and corresponding simulation environments are constructed, so that development of wireless local area network technology and performance evaluation of wireless local area network equipment can be performed through the constructed simulation environments in experiments.
The implementation details of the technical solutions of the embodiments of the present application are described in detail below:
fig. 4 shows a flowchart of an interference processing method applied to a wireless local area network, which may be performed by a device or system having a computing processing function, according to one embodiment of the present application. Referring to fig. 4, the interference processing method applied to the wireless lan at least includes steps S410 to S430, and is described in detail as follows:
in step S410, in the interference environment of the wireless local area network, the interference index information generated by the interference source for the target device is measured, and an index measurement result is obtained.
In one embodiment of the present application, the interference environment of the wireless local area network may be, for example, an indoor environment, an office environment, a subway station environment, a high-speed mobile environment, or the like. Optionally, interference index information generated by an interference source in each interference environment for the target device can be measured in a plurality of interference environments of the wireless local area network respectively to obtain index measurement results corresponding to each interference environment, and further statistics results of index characteristic values corresponding to each interference environment can be generated according to the index measurement results corresponding to each interference environment, so that simulation environments corresponding to each interference environment can be constructed later, and development of wireless local area network technology and performance evaluation of the wireless local area network device can be performed in different constructed simulation environments.
It should be noted that: the target device is the selected device to measure the signal interference experienced. Alternatively, the target device may be a wireless local area network device, such as a site device implemented by a smart phone, computer, or the like.
Optionally, the indicator measurements include interference signal measurements and experience indicator measurements. The interference signal measurement result is a result used for representing the measurement of the related index of the interference signal, and can be an interference signal of a wireless local area network or an interference signal of a non-wireless local area network; the experience index measurement result is used for representing the experience index measurement result, such as a click through rate, of an application program (such as a video application, a game application, etc.) under the corresponding interference environment.
It should be noted that: the wireless local area network interference signal includes at least one of: co-channel interference signals, adjacent channel interference signals and overlapping channel interference signals. The interference signal of the non-wireless local area network may be, for example, a signal of a mobile communication network (e.g., 4G, 5G, etc.), etc.
Optionally, the interference signal measurement comprises at least one of the following information: the method comprises the steps of generating the number of wireless local area network devices interfering with target devices, generating signal emission intensity of the wireless local area network devices interfering with the target devices, generating channel utilization rate of wireless local area network channels of the target devices, generating signal-to-noise ratio of the wireless local area network channels of the target devices, generating error vector magnitude EVM of the wireless local area network channels of the target devices, generating packet error rate of the wireless local area network connected with the target devices, generating wireless local area network data flow of the interference with the target devices, generating signal intensity of non-wireless local area network interfering with the target devices and generating bandwidth of the non-wireless local area network interfering with the target devices.
Optionally, the number of wireless lan devices that generate interference to the target device, the signal emission intensity of the wireless lan devices that generate interference to the target device, the channel utilization rate of the wireless lan channel where the target device is located, the signal-to-noise ratio of the wireless lan channel where the target device is located, the error vector magnitude EVM of the wireless lan channel where the target device is located, the packet error rate of the wireless lan to which the target device is connected, and the like may be measured by obtaining beacon frame data of Wi-Fi APs of different channels based on Wi-Fi scanning APIs provided in an operating system of the device.
The wireless local area network data flow which generates interference to the target equipment can respectively carry out air-interface packet capturing on different channels through a plurality of packet capturing software (such as Wi-Fi air-interface sniffer) to measure. The signal strength of the non-wireless local area network that interferes with the target device and the bandwidth of the non-wireless local area network that interferes with the target device may be measured using a spectrum analyzer that supports 2.4GHz and 5GHz reviews.
In one embodiment of the present application, the measurement duration of the interference indicator information is inversely related to the interference stability of the interference environment. That is, if the stability of an interference environment is poor, it means that the signal interference condition in the interference environment varies greatly, so that a long time is required for measurement in order to obtain more accurate interference index information; on the contrary, if the stability of an interference environment is better, it means that the signal interference condition inside the interference environment has smaller variation, and more accurate interference index information can be obtained without measuring longer time under the condition. The technical scheme of the embodiment enables the measurement duration to be flexibly adjusted according to the interference stability of the interference environment, and further improves the measurement efficiency on the premise of guaranteeing the measurement accuracy of the interference index information.
With continued reference to fig. 4, in step S420, statistics of the index feature values are generated according to the measured index measurement result, where the statistics of the index feature values include statistics of interference signal feature values and statistics of experience index feature values.

The foregoing describes the implementation process of the embodiments of the present application, and in order to further describe the details of the embodiments of the present application, the following details are described in connection with specific application scenarios:
in a specific application scenario of the present application, the processing for Wi-Fi air interface interference environments may be divided into three main flows: the method comprises the steps of collecting and recording interference environments, intercepting and quantifying the characteristics of the interference environments, and playing back and reproducing according to the interference characteristic variables. The following are respectively described:
the collection and recording of the interference environment is mainly to measure and record the interference index data in the interference environment. Specifically, the goal of the collection is to obtain the intensities of the same-frequency interference, adjacent-frequency interference, overlapping-frequency interference, and four interference dimensions of non-Wi-Fi signal interference for the current Wi-Fi connection (the current Wi-Fi connection refers to Wi-Fi connected to the target device selected for measuring the signal interference condition).
In Wi-Fi environment, there is a technical feature of CSMA/CA (Carrier Sense Multiple Access with Collision Avoid, carrier sense multiple access with collision avoidance) air interface contention, where CSMA/CA is an algorithm for avoiding collision of data transmission between stations, specifically, before transmitting data, if a channel is detected to be idle, waiting for a period of time, then detecting whether the channel is idle again, if it is still idle, immediately transmitting data, otherwise, waiting for a certain time at random, and detecting channel state again after expiration of an equal time. For this technical feature, the collection of interference may include the following: the number of Wi-Fi devices interfered, the signal strength sent by the Wi-Fi devices interfered, the channel utilization rate/signal to noise ratio/EVM of the current channel, the packet error rate of the current Wi-Fi connection, the data flow of Wi-Fi interference signals, the signal strength and approximate bandwidth of non-Wi-Fi interference signals, experience indexes (such as a cartoon rate and a control reaction time) of application programs (such as cloud video application) and the like.
The above-mentioned points, the number of interfering Wi-Fi devices, the signal strength transmitted by the interfering Wi-Fi devices, the channel utilization/signal-to-noise ratio/EVM of the current channel, the packet error rate of the current Wi-Fi connection, etc. may be recorded by obtaining beacon frame data of Wi-Fi APs of different channels based on a Wi-Fi scanning API provided in the operating system of the device. The data flow of Wi-Fi interference signals can be recorded by carrying out air interface packet capturing on different channels through a plurality of packet capturing software (such as Wi-Fi air interface sniffer). The signal strength and approximate bandwidth of non-Wi-Fi interfering signals may be recorded using a spectrum analyzer supporting 2.4GHz and 5GHz reviews. The experience index of the application may record data of the application background server (e.g., record background data of the cloud video application server).
It should be noted that: the recording time of the index data can be set according to the requirement, and in order to ensure certain characteristic interception efficiency, the scene with larger disturbance environment variation (such as a subway scene) can be longer than the recording time of the scene with smaller disturbance environment variation (such as a family scene).
After the collection and recording of the interference environment, the next step is to intercept and quantify the characteristics of the interference environment, which can be divided into four types of data: firstly, counting the same-frequency, adjacent-frequency and overlapping-frequency interference recording values of Wi-Fi; secondly, wi-Fi is used for recording direct measurement results of values of the same-frequency, adjacent-frequency and overlapping-frequency interference; thirdly, the characteristic value of the non-Wi-Fi interference signal; fourth, the experience index value of the application.
The statistics result of the co-frequency, adjacent frequency and overlapping frequency interference recording values of Wi-Fi is a result value obtained by using a calculation formula by a chip or software and hardware of Wi-Fi equipment, and is not a value obtained by direct measurement, such as channel utilization rate/signal to noise ratio/EVM, and the characterization may be performed by obtaining an average number of the calculation result values or other statistics data (such as a maximum value and a standard deviation) in the recording time. One example of statistics of co-channel, adjacent channel, and overlapping interference recording values for Wi-Fi is shown in table 1 below:
interference type Channel utilization Signal to noise ratio Error vector magnitude EVM
Co-channel interference 32.1% 13dB -18dB
Adjacent channel interference 18.2% 16dB -2dB
Interference of overlapping frequencies 20.5% 20dB -6dB
TABLE 1
In table 1, specific values in the statistics of the recorded values of co-frequency interference, adjacent frequency interference and overlapping frequency interference of Wi-Fi are average values in the measurement process.
The direct measurement results of the co-frequency, adjacent frequency and overlapping frequency interference recording values of Wi-Fi can be obtained directly through measurement, such as the number of the interfered Wi-Fi devices, the signal strength of the interfered Wi-Fi devices, the frequency width of the interfered Wi-Fi devices, the data flow of Wi-Fi interference signals and the like. One specific example is shown in table 2:
Figure BDA0003391388470000161
TABLE 2
The characteristic value of the non-Wi-Fi interference signal can be used to represent the continuous signal strength of the non-Wi-Fi interference signal in the time domain and the frequency domain, and specifically can be characterized into a bandwidth distribution and a signal strength distribution in a selected time granularity, as shown in table 3, the non-Wi-Fi interference signal can be divided into three time periods (only by way of example, in other embodiments of the present application, the non-Wi-Fi interference signal can be divided into any number of time periods), and then the bandwidth corresponding to the strongest average signal strength in each time period is selected and recorded as bandwidth distribution 1; then continuously selecting the frequency width corresponding to the average signal strength of the second strength, and marking the frequency width as the frequency width distribution 2; the bandwidth profile corresponding to the first 3 (by way of example only, any number may be selected in other embodiments of the present application) average signal strengths ordered by signal strength is sequentially selected for recording. As shown in table 3:
Figure BDA0003391388470000162
TABLE 3 Table 3
The experience index values of the application program can be data recorded from an application program background server, for example, the application program background server can be a cloud video application background server, and the values can be recorded directly without being characterized, for example, as shown in the following table 4:
katon rate Average video frame delay Average control reaction time
1.27% 4.5ms 3.2ms
TABLE 4 Table 4
After the feature interception and quantization processing of the interference environment is completed, playback and reproduction processing can be performed according to the interference feature variable, that is, a simulated interference environment can be constructed, and the following methods of reproduction processing are listed:
interference with one of the environmental playback and reproduction modes: the simulation environment approximating the experience index values shown in table 4 was constructed using the foregoing tables 2 and 3, and reproduction of the disturbance environment was achieved.
Specifically, the characteristic variables shown in table 2 are used for reproduction of Wi-Fi interference environment, firstly, the number of devices with equal number is configured in a laboratory environment according to the number of devices with co-frequency/adjacent frequency/overlapping frequency interference, then, the bandwidths of the co-frequency/adjacent frequency/overlapping frequency interference devices are respectively configured, and data streams (such as TCP data streams or UDP data streams) are sent on the devices, so that the total flow rate of the interference data streams of each frequency band is equal to that recorded in table 2.
The characteristic variables shown in table 3 are used for reproducing the non-Wi-Fi signal interference environment, and the full-band signal generator capable of operating at 2.4G/5GHz is used, so that according to the time periods of table 3, the frequency bandwidth distribution and the frequency spectrum transmission configuration of average signal intensity are adjusted at the beginning of each time period, and the effect of reproducing the non-Wi-Fi signal interference environment is achieved.
After the interference environment is reappeared, background data of the application program server is verified, the relation between the actual experience index value and the user experience data value shown in the table 4 is confirmed, if the difference is large, partial characteristic variables in the table 2 and the table 3 can be properly adjusted, the actual experience index value is close to the user experience data value shown in the table 4 as much as possible, and then a simulation environment matched with the actual interference environment can be constructed.
Interference with the second mode of playback and reproduction: the simulated environment approximating the experience index values shown in table 4 was constructed using the disturbance environment characteristic variables shown in table 1, to achieve reproduction of the disturbance environment.
The characteristic variables shown in table 1 are used for representing interference result values in the same-frequency/adjacent-frequency/superimposed-frequency environment, are calculated according to a formula, and objectively represent the interference degree. Therefore, in the reproduction of a laboratory scene, a combination of Wi-Fi equipment and a full-band signal generator capable of operating at 2.4G/5GHz can be used, the number, bandwidth and flow of the equipment are not limited, and the aim is to construct a characteristic numerical result similar to that shown in table 1.
After the interference environment is reappeared, background data of the application program server is verified, the relation between the actual experience index value and the user experience data value shown in the table 4 is confirmed, if the difference is large, part of characteristic variables in the table 1 can be properly adjusted, the actual experience index value is as close as possible to the user experience data value shown in the table 4, and then a simulation environment matched with the actual interference environment can be constructed.
In summary, the technical scheme of the embodiment of the application can record the interference index data of various interference environments (such as indoor environments, office environments, subway station environments and high-speed mobile environments), so that the interference environments of the wireless local area network can be restored in a laboratory environment, playback effects of the interference environments are constructed, and development of wireless local area network technology and performance evaluation of the wireless local area network equipment are facilitated in the restored interference environments.
