Background technique

Wireless local area networks (Wireless Local Area Networks, WLAN) use radio frequency technology and use electromagnetic waves to conduct communication links in the air, thereby providing a faster communication method, and thus becoming an indispensable and important part of modern mobile communication. However, due to the limited coverage of the wireless access points (Access Points, AP), there is a problem of signal coverage vulnerabilities in the wireless network, that is, the wireless terminal (Station, STA) cannot receive in the weak signal coverage area The signal strength of the AP or the received signal is too weak. As a result, the STA cannot connect to the WLAN at the weak coverage location or cannot access the Internet because of the weak signal, which seriously affects the user's Internet experience. Therefore, detecting the quality of WLAN network signal coverage is a problem that needs to be solved urgently in wireless network optimization.

In the prior art, a manual test solution is usually adopted to test the weak coverage area, that is, the operator holds the tester to detect whether the AP has a weak coverage area by detecting the signal strength emitted by the AP, which has the defects of high cost and long time consumption . In order to solve the above-mentioned defects, the prior art also proposes an automatic detection scheme, by acquiring the signal strength value of the signal transmitted by the STA to detect whether the AP has a weak coverage area. However, in this solution, because the performance bottleneck of the STA itself may affect the test result, the existing technology still has the problem that the test result is inaccurate and the operator needs to perform secondary detection.

Step 201: The wireless signal coverage detection device acquires the signal quality information recorded by the AP.

The signal quality information can be used by the analysis module to analyze the signal coverage quality corresponding to each AP, that is, the signal quality information is a reference basis for judging whether there is a loophole in the signal coverage range of the AP.

Among them, the drop frequency is used to indicate the number of times the STA accesses the AP again after going offline within a predetermined time. The roaming frequency is used to indicate the number of times the STA roams to one AP on another AP within a predetermined time. The uplink negotiation rate is used to indicate the data transmission rate at which the STA transmits data to the AP.

The following is a detailed description with specific embodiments: FIG. 3 is a schematic diagram of a test scenario in an embodiment of the present application. The test scenario includes AP1-4 (respectively AP1, AP2, AP3, AP4) and STA1-5 (respectively Are: STA1, STA2, STA3, STA4, STA5). In the specific implementation process of the embodiments of the present application, the STA may be a computer, a smart phone, and other devices. It should be noted that in actual applications, the number of STAs and APs can be one or more. The number and distribution of STAs and APs in the test scenario shown in FIG. 3 are only schematic examples, and this application does not do this. limited.

With reference to FIG. 3, it can be seen from the figure that the shaded portion may be a weak signal coverage area. Therefore, the STA (that is, STA3) in this area will continue to drop. And, if STA3 moves in this area, STA3 will roam between AP2 and AP4.

Specifically, each AP separately counts the number of dropped calls and the number of roaming times within the detection period (that is, the duration of the period can be set) of the STA (ie, the STA connected to the AP) (in this embodiment, only the number of dropped calls and roaming The frequency is taken as an example of signal quality information). For example, after STA3 accesses AP2, due to the weak signal strength, STA3 leaves AP2, and then STA3 accesses AP2 again, that is, STA3 drops on AP2 once, and AP2 disconnects the STA identification information (that is, STA2) Correspond to the number of times of disconnection recorded in the local list. And, assuming that in this test scenario, STA3 continues to move at the edge of the shadow area within a specified time, therefore, when STA3 moves to the shadow edge area covered by AP2, STA3 will access AP2. Then, if STA3 When moving to the shadow edge area covered by AP4, STA3 will roam from AP2 to AP4. It can be recorded that STA3 roams once from AP2 to AP4, and AP2 records the identification information of STA3 and the number of roaming times (specific roaming times may include roaming objects, that is, roaming from AP2 to AP4 once) in the local list. In this test scenario, AP1, AP3, and AP4 will also count the number of disconnections and roaming times of their STAs. However, in this test scenario, AP1 and AP3 do not have weak coverage areas. Therefore, the number of disconnections and roaming times of the STAs belonging to AP1 and AP3 will be very low (probably due to disconnection or other reasons) roaming).

At the arrival time of the cycle, AP1-4 calculates the drop frequency and roaming frequency corresponding to each STA in the current cycle based on the detected drop times and roaming times of each STA. In one embodiment, AP1-4 can also directly record the information in the local list, that is, the STA ID and the corresponding number of disconnections and the STA ID and the corresponding number of roaming times to the collection module, and the collection module then calculates each AP The dropout frequency and roaming frequency corresponding to the STA to which it belongs.

Suppose that AP1 records that the drop frequency of STA1 is 0.004 and the roaming frequency is 0. AP2 records: STA2's drop frequency is 0.020 and roaming frequency is 0.302; STA3's drop frequency is 0.070 and roaming frequency is 0.062. AP3 records: STA4's drop frequency is 0 and roaming frequency is 0. AP4 records: STA5 has a drop frequency of 0.024 and a roaming frequency of 0; STA3 has a drop frequency of 0 and a roaming frequency of 0.177.

In step 202, the wireless signal coverage detection device determines whether the AP has a weak signal coverage area based on the signal quality information.

Specifically, in the embodiments of the present application, the present application may use the trained mathematical model in combination with the acquired signal quality information to classify the AP. Among them, the trained mathematical model contains decision information. The determination method of the decision information will be described in detail in the following embodiments. The mathematical model can be based on the decision information, that is, the signal quality information is compared with the decision information, thus based on Compare the results and classify the AP. The classification results include: a weak coverage AP with a weak coverage area in the AP's signal coverage, or a good coverage AP without a weak coverage area in the AP's signal coverage, or it can be called Normal AP. The following is a detailed description with specific embodiments:

Specifically, the mathematical model is used as the forest classification model, that is, the binary classification method is used as an example, and the signal quality information recorded by each AP, that is, the dropped frequency and the roaming frequency obtained in step 101 are classified through the forest model. Specifically, the mathematical model is provided with first decision information corresponding to the drop frequency and second decision information corresponding to the roaming frequency. During the classification process, the mathematical model will include at least one recorded drop frequency exceeding the first decision The APs of the information are classified as weak coverage APs, and vice versa as good coverage APs. The mathematical model classifies APs containing at least one recorded roaming frequency exceeding the second decision information as weak coverage APs, and vice versa as good coverage APs. That is to say, if the drop frequency of multiple STAs recorded in an AP, as long as it contains a drop frequency that exceeds the first decision information, the mathematical model divides the AP into a weak coverage AP. Example: Taking the first decision information as 0.06 and the second decision information as 0.14 as an example, still referring to the numerical example in step 2, AP1 will be classified as good coverage AP, AP2 will be classified as weak coverage AP, AP3 It will be classified as a good coverage AP, and AP4 will be classified as a weak coverage AP.

In the embodiment of the present application, the operator may also perform manual verification based on the detection result to update the first judgment information and the second judgment information. Specifically, it is assumed that the first decision information is 0.06 and the second decision information is 0.14. However, in actual tests, the occurrence frequency of the STA corresponding to the AP for multiple times (for example, 100 times) is 0.058. Subsequently, after the actual detection by the operator, it is found that this type of STA (that is, the STA with a drop frequency of 0.058) is indeed in a weak coverage area. Then, the operator can update the first judgment information, that is, update to 0.058. The update of the second judgment information is similar to the first judgment information, and will not be repeated here. Thereby further improving the accuracy and reliability of the mathematical model for AP division.

In addition, as described above, the mathematical model classifies APs according to the first decision information corresponding to the dropped frequency and the second decision information corresponding to the roaming frequency (ie, divided into weak coverage APs or strong coverage APs), and The determination of the first decision information and the second decision information requires training the mathematical model in advance to obtain both. The following describes the training method of the mathematical model in detail:

As shown in FIG. 4, it is one of the schematic flowcharts of the wireless signal coverage detection method in the embodiment of the present application. In FIG. 4:

Before describing the training method in the embodiment of the present application, first, the training scene in the embodiment of the present application will be described with reference to the drawings. FIG. 5 is a schematic diagram of a training scenario in an embodiment of this application. Specifically, in the embodiment of the present application, the training scene may be any space such as a room, and multiple APs are set in the room. The AP setting method may be as shown in FIG. 5. In the embodiments of the present application, the AP deployment method shown in FIG. 5 is only an example of suitability, and its purpose is to enable the signal coverage of multiple APs to cover the entire room, that is, the operator can manually Detect the signal coverage of the entire room to determine that there are no signal coverage holes in the room. For specific manual detection methods, please refer to the existing technical solutions, which will not be repeated here. Referring to FIG. 5, the training scenario includes AP1-4 (AP1, AP2, AP3, AP4) and STA1-5 (STA1, STA2, STA3, STA4, and STA5, respectively). In the specific implementation process of the embodiments of the present application, the STA may be a computer, a smart phone, and other devices. It should be noted that in actual applications, the number of STAs and APs can be one or more. The number and distribution of STAs and APs in the training scenario shown in FIG. 4 are only schematic examples, and this application does not do this. limited.

Step 401: Construct a weak coverage area.

Specifically, in the embodiment of the present application, each AP in the training scene may be controlled to be closed by the controller separately, or two or more APs may be closed at the same time and a weak coverage area has been constructed, that is, the AP of the closed AP The original signal coverage area may be partially or completely weak coverage area. . It should be noted that the correspondence between the identification information of the AP and the location information is pre-stored in the controller, that is, the controller can learn the specific location of the weak coverage area by turning off the AP.

The process of constructing a weak coverage area in the training scene will be described in detail below in conjunction with FIG. 5:

The controller can turn off AP1 in sequence, and within a predetermined period of time (for example, 1 hour off) to turn off AP1, obtain the number of times of disconnection and roaming of each STA recorded by AP2-4. The specific acquisition steps are similar to those in scenario 1, and are not repeated here. Subsequently, the controller turns on AP1 and turns off AP2, and obtains the number of disconnections and roaming times of each STA recorded by AP1, AP3, and AP4 within a predetermined duration, and so on, and turns off AP3 and AP4, respectively.

Step 402, the wireless signal coverage detection device obtains the signal quality information recorded by the AP.

This step is the same as step 101 in scenario 1, which is not described here.

Step 403: The wireless signal coverage detection device determines the decision information based on the signal quality information.

Specifically, in the embodiment of the present application, after the controller turns off the AP, it can confirm that the location of the AP is a weak coverage area. Combining this feature, the way to obtain the decision information may be: detecting the worst signal quality information (for example, the maximum drop frequency) of the signal quality information of all STAs recorded by each AP except the closed AP, and the corresponding STA That is, the STA in the weak coverage area and the target STA in the embodiment of the present application. Subsequently, the system may confirm that the signal quality information with the best quality among the signal quality information recorded by the target STA in each AP record is the selected signal quality information of the target STA. For example, if the maximum value of the drop frequency is 0.96 in the records of each AP, the STA1 corresponding to the maximum drop frequency is recorded as the target STA, and the record of STA1 in each AP is detected , STA1 has been confirmed as the target STA, then the area where STA1 is located is the weak coverage area. Therefore, all APs contain the signal quality information of STA1, that is, the AP with the drop frequency value is the AP containing the weak coverage area, then, The record of the AP in the drop frequency of STA1 corresponds to the minimum value of the drop frequency of STA1, which is the decision information corresponding to the drop frequency. The following is a detailed description with specific embodiments.

Specifically, referring to FIG. 5, taking AP1 as an example, after the controller turns off AP1, it may determine that the shaded portion shown in FIG. 5 is a weak coverage area. Within a predetermined time period, it is assumed that the drop frequency of STA1 recorded by AP2 is 0.06 and the roaming frequency is 0.14; the drop frequency of STA2 is 0 and the roaming frequency is 0; the drop frequency of STA5 is 0.03 and the roaming frequency is 0.08. The drop frequency of STA1 recorded by AP3 is 0.062 and the roaming frequency is 0.15; the drop frequency of STA3 is 0 and the roaming frequency is 0; the drop frequency of STA5 is 0.03 and the roaming frequency is 0.09. The offline frequency of STA4 recorded by AP4 is 0, and the roaming frequency is 0; the offline frequency of STA5 is 0.03, and the roaming frequency is 0.09 (where the AP records 0 for some STAs may be because the AP is far away from the STA) Therefore, the signal coverage of the AP cannot cover the area where the STA is located, so the STA will not be connected to the AP). Therefore, when setting the first judgment information, since the controller confirms that the shadow area is a weak coverage area, and from the above record, it can be known that the STA corresponding to the maximum value of the drop frequency (ie, 0.062) is STA1, and the maximum value of the roaming frequency (0.15 ) The corresponding STA is STA1, and it can be confirmed that STA1 is in a weak coverage area. Therefore, the first decision information and the second decision information can be respectively set to the minimum value of the drop frequency of STA1 and the minimum value of the roaming frequency recorded in AP2-AP4 (that is, the signal of the best quality in the signal quality information of STA1 Quality information), that is, the first decision information is 0.06, and the second decision information is 0.14. Subsequently, the controller updates the first decision information and the second decision information according to other constructed weak coverage scenarios, for example, the values recorded in the weak coverage scenario constructed after closing AP2. That is, if the drop frequency and / or roaming frequency of the STA appearing in the weak coverage area is lower than the first and second decision information that have been set, the first and second decision information are updated. In the embodiment of the present application, the method for updating the decision information may be: the system confirms that the specific value of the newly acquired selected signal quality information is less than the specific value of the corresponding decision information, then the operator may confirm the Whether the newly acquired STA corresponding to the selected signal quality information is indeed in a weak coverage area, but not for other reasons, for example, caused by STA performance bottlenecks. And after confirmation, the system replaces the newly acquired selected signal quality information with the original decision information.

In an embodiment, the controller may not update the decision information every time, but the first decision information and the second decision information are set based on the values recorded by all APs in the training scenario. The specific setting steps are: The above is similar and will not be repeated here.

Then, the operator can modify the layout of the training scene multiple times, including the size of the training scene area and the number and distribution positions of APs and STAs, and divide the APs in the training scene according to the first decision information and the second decision information For the specific division steps, refer to the steps in scenario 1, which will not be repeated here. During the training process, since the controller can confirm the location of the weak coverage area, the controller can determine the first judgment information and / or the first decision information according to the location of the weak coverage area, and the current statistics of the STA drop frequency and roaming frequency. The second judgment information is updated. Specifically, suppose that in another training scenario, after the controller turns off each AP separately, the STA has a drop frequency of 0.059 and a roaming frequency of 0.016. And, when the controller confirms that the record appears, the STA is in the area covered by the closed AP, that is, the weak coverage area. Therefore, the controller may update the first decision information to 0.059, while the second decision information is not updated.

In the embodiment of the present application, the operator can train the mathematical model by setting a large number of training scenarios to optimize the mathematical model, thereby improving the accuracy and reliability of the classification result of the mathematical model to classify the AP.

In addition, in the embodiment of the present application, during the training process, the mathematical model may divide the STA by introducing the uplink negotiation rate contrast value, the downlink negotiation rate contrast value, the delay contrast value, and / or the jitter contrast value as described above, That is, if it is determined whether the STA is a weak STA, the interference of the decision information confirmed by the AP due to the hardware problem of the STA can be excluded. For example, when the drop frequency of a STA recorded by an AP is high, but the contrast value of the upstream rate and the downlink rate corresponding to the STA is very low, the cause of the phenomenon that the STA's drop frequency and roaming frequency are high may be determined. It is caused by the STA's own hardware abnormality. Then, the analysis module may further determine whether there is a weak coverage area in the signal coverage of the AP through related records of other STAs.

In summary, in the technical solution in the embodiments of the present application, a weak coverage environment has been constructed by shutting down one or more APs to obtain corresponding judgment information, so that the system can determine whether the STA is in a weak coverage area based on the judgment information, or In other words, whether there is a weak coverage area in the test area to detect, in order to realize the automatic detection of the weak coverage area of the area, that is, to provide a simple and convenient test method of signal coverage, to effectively reduce labor costs and improve Test efficiency and accuracy.
