Description
Technical Field
The embodiment of the application relates to the field of communication, in particular to a wireless signal coverage detection method and device.
Background
Wireless Local Area Networks (WLANs) utilize radio frequency technology and use electromagnetic waves to perform communication links in the air, thereby providing a faster communication method, and becoming an indispensable important component in modern mobile communications. However, because the coverage of an Access Point (AP) is limited, there is a problem of a signal coverage hole in a wireless network, that is, a wireless terminal (Station, STA) cannot receive a signal of the AP in a weak signal coverage area or the received signal strength is too weak, so that the STA cannot connect to the WLAN in a weak coverage position, or the STA cannot normally surf the internet due to too weak signal, which seriously affects the user experience of surfing the internet. Therefore, detecting the network signal coverage quality of the WLAN is an urgent problem to be solved in the wireless network optimization work.
In the prior art, a manual test scheme is usually adopted to test a weak coverage area, that is, an operator holds a tester by hand to detect whether the AP has the weak coverage area by detecting the signal intensity emitted by the AP. In order to solve the above-mentioned drawbacks, the prior art further provides an automatic detection scheme, which obtains a signal strength value of a STA transmitting signal to detect whether the AP has a weak coverage area. However, in this scheme, since the performance bottleneck of the STA itself may affect the test result, the problem still exists in the prior art that the test result is inaccurate and an operator is required to perform secondary detection.

Before describing the technical solution of the embodiment of the present application, a system architecture of the embodiment of the present application is first described with reference to the drawings. Referring to fig. 1, as fig. 1 is a schematic diagram of a system architecture in an embodiment of the present application, in fig. 1, elements in the system include, but are not limited to: the Wireless signal coverage detection device comprises an AP, a Switch (Switch), a Wireless network Controller (AC), an STA and a Wireless signal coverage detection device, wherein the Wireless signal coverage detection device can comprise an acquisition module and an analysis module. The acquisition module can be in communication connection with the AP, the Switch and the AC respectively, and the acquisition module can acquire parameter indexes from the AP, the Switch and the AC. It should be noted that, taking the same floor as an example, there is one AC in the same floor, the same floor includes multiple office areas, each office area has one Switch, and each office area includes multiple rooms, and each room may have multiple APs. In the embodiment of the present application, each AP may record a status index of a relevant STA, and then the AP in each room sends the obtained index to the Switch, so that the Switch aggregates information of multiple APs. Subsequently, the Switch in each area sends the aggregated information (the information carries the status indicator of the STA corresponding to each AP) to the AC in the floor where the Switch is located. Then, the acquisition module can acquire the recorded indexes from the APs, and then converge the indexes and send the collected indexes to the analysis module for analysis. The acquisition module may further acquire an index recorded by the AP in units of rooms from the Switch in each area, and the acquisition module may further acquire related information reported by the Switch in units of areas from the AC. The analysis module is configured to classify the APs according to the parameters and the mathematical model acquired by the acquisition module, and a specific process will be described in detail in the following embodiments.
With reference to the system architecture shown in fig. 1, fig. 2 is a schematic flow chart of a wireless signal coverage detection method in the embodiment of the present application, where in fig. 2:
in step 201, the wireless signal coverage detection device obtains signal quality information recorded by the AP.
Specifically, in the embodiment of the present application, the wireless signal coverage detection device may obtain, from the AP, the AC, and/or the Switch end, signal quality information recorded by each AP in each room through the acquisition module. The signal quality information may 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 determining whether a hole exists in the signal coverage area of the AP. In embodiments of the present application, the signal quality information may include, but is not limited to: a dropped frequency, a roaming frequency, an uplink negotiation rate counter-difference value, a downlink negotiation rate counter-difference value, a delay counter-difference value, a jitter value and/or a jitter counter-difference value. And the disconnection frequency is used for indicating the times of accessing the AP again after the STA is offline in the AP in the preset time. The roaming frequency is used to indicate the number of times a STA roams from one AP to another AP within a predetermined time. The uplink negotiated rate is used to indicate the data transmission rate at which the STA transmits data to the AP. The downlink negotiation rate is used for indicating the data transmission rate of the AP for transmitting data to the STA; the uplink negotiation rate counter value is used for indicating the difference between the maximum value and the minimum value of the data transmission rate of the STA for transmitting data to the AP, wherein if the uplink negotiation rate counter value of any STA is lower than the uplink negotiation rate counter value judgment information in at least one STA, the signal function abnormity of the STA corresponding to the uplink negotiation rate counter value lower than the uplink negotiation rate counter value judgment information can be confirmed; the downlink negotiation rate counter value is used for indicating the difference between the maximum value and the minimum value of the data transmission rate of the AP for transmitting data to the STA, wherein if the downlink negotiation rate counter value of any STA is lower than the downlink negotiation rate counter value judgment information in at least one STA in the test scene, the signal function abnormity of the STA corresponding to the downlink negotiation rate counter value lower than the downlink negotiation rate counter value judgment information is confirmed; the time delay value is used for indicating the time length used by the AP for transmitting the data to the STA; the delay inequality value is used for indicating the difference between the maximum value and the minimum value of the time length used for transmitting the data to the STA by the AP, wherein if the delay inequality value of any STA is lower than the delay inequality value judgment information in at least one STA in the test scene, the signal function abnormity of the STA corresponding to the delay inequality value lower than the delay inequality value judgment information is confirmed; the jitter value is used for indicating the time delay variation between two adjacent data packets of the STA corresponding to the AP; and the jitter contrast value is used for indicating the difference between the maximum value and the minimum value of the time delay variation between two adjacent data packets of the STA corresponding to the AP, wherein if the jitter contrast value of any STA in at least one STA is lower than the jitter contrast value judgment information, the signal function abnormality of the STA corresponding to the jitter contrast value lower than the jitter contrast value judgment information is confirmed.
The following is a detailed description of specific examples: FIG. 3 is a schematic diagram of a test scenario in the embodiment of the present application, where the test scenario includes AP1-4 (AP 1, AP2, AP3, AP4, respectively) and STA1-5 (STA 1, STA2, STA3, STA4, STA5, respectively). In the specific implementation process of the embodiment of the application, the STA may be a computer, a smart phone, or other devices. It should be noted that, in practical applications, the number of the STAs and the APs may be one or more, and the number and the distribution manner of the STAs and the APs in the test scenario shown in fig. 3 are only exemplary, which is not limited in this application.
In conjunction with fig. 3, it can be seen that the shaded portion may be a weak signal coverage area, and therefore, the STA (i.e., STA3) in the area will continue to be dropped. Also, if STA3 moves within the area, STA3 will roam between AP2 and AP 4.
Specifically, each AP respectively counts the number of dropped calls and the number of roaming times of the STA (i.e., the STA accessing the AP) in the detection period (the period duration may be set) (in this embodiment, the number of dropped calls and the number of roaming times are only taken as the signal quality information as an example). For example, the following steps are carried out: after the STA3 accesses the AP2, because the signal strength is weak, the STA3 leaves the AP2, and then the STA3 accesses the AP2 again, that is, the STA3 drops the AP2 for 1 time, and the AP2 records the identification information of the STA (i.e., the STA2) and the number of dropped times in a local list. And, assume that under this test scenario, STA3 continues to move around the edge of the shadow region within a specified time, so when STA3 moves into the shadow edge region covered by AP2, STA3 will access AP2, and subsequently, if STA3 moves into the shadow edge region covered by AP4, STA3 will roam from AP2 to AP 4. It can be said that STA3 roams from AP2 to AP4 once, and AP2 records the identification information of STA3 in the local list corresponding to the number of roams (the specific number of roams may include the object of roaming, i.e., roaming from AP2 to AP4 once). In the test scenario, AP1, AP3, and AP4 also count the number of dropped calls and roaming times of the STAs. However, since in the present test scenario, there is no weak coverage area for AP1 and AP3, the values of the dropped times and roaming times of the STAs in AP1 and AP3 will be low (may be dropped or roaming due to other reasons).
At the arrival time of the period, the AP1-4 calculates the dropped frequency and roaming frequency corresponding to each STA in the period based on the detected dropped frequency and roaming frequency of each STA, respectively. In an embodiment, the AP1-4 may also directly send the recorded information in the local list, that is, the STA id and the corresponding number of dropped calls and the STA id and the corresponding number of roaming times to the acquisition module, and the acquisition module calculates the dropped frequency and the roaming frequency corresponding to the STA to which each AP belongs.
Assume that AP1 has recorded: the frequency of dropped STA1 is 0.004 and the roaming frequency is 0. AP2 has recorded: the disconnection frequency of the STA2 is 0.020, and the roaming frequency is 0.302; the dropped frequency of STA3 is 0.070, and the roaming frequency is 0.062. AP3 has recorded: the dropped frequency of STA4 is 0 and the roaming frequency is 0. AP4 has recorded: the disconnection frequency of the STA5 is 0.024, and the roaming frequency is 0; the dropped frequency of STA3 is 0 and the roaming frequency is 0.177.
In step 202, the wireless signal coverage detection device determines whether the AP has a signal weak coverage area based on the signal quality information.
Specifically, in the embodiment of the present application, the trained mathematical model may be used in combination with the acquired signal quality information to classify the APs. Wherein the trained mathematical model includes decision information, the determination method of the decision information will be described in detail in the following embodiments, the mathematical model may be based on the decision information, that is, the signal quality information is compared with the decision information, so as to classify the APs based on the comparison result, and the classification result includes: a weak coverage AP with a weak coverage area exists in the signal coverage area of the AP, or a good coverage AP with a weak coverage area does not exist in the signal coverage area of the AP, or may be referred to as a normal AP. The following is a detailed description of specific examples:
specifically, the mathematical model is taken as a forest classification model, that is, a two-classification method is taken as an example, and the signal quality information recorded by each AP, that is, the offline frequency and the roaming frequency acquired in step 201 are classified through the forest model. Specifically, the mathematical model is provided with first judgment information corresponding to the dropped connection frequency and second judgment information corresponding to the roaming frequency, and in the classification process, the mathematical model classifies the AP containing at least one recorded dropped connection frequency exceeding the first judgment information as a weak coverage AP, otherwise, the AP is a good coverage AP. The mathematical model classifies an AP containing at least one recorded roaming frequency exceeding the second decision information as a weak coverage AP, and otherwise as a good coverage AP. That is, if only one dropped frequency exceeding the first decision information is included in the dropped frequencies of the STAs recorded in an AP, the mathematical model classifies the AP as a weak coverage AP. For example, the following steps are carried out: taking the first decision information as 0.06 and the second decision information as 0.14 as an example, and still referring to the values in step 2, the AP1 will be classified as a good coverage AP, the AP2 will be classified as a weak coverage AP, the AP3 will be classified as a good coverage AP, and the AP4 will be classified as a weak coverage AP.
In the embodiment of the application, the operator may further perform manual verification according to the detection result to update the first decision information and the second decision information. Specifically, it is assumed that the first decision information is 0.06 and the second decision information is 0.14, but in an actual test, the frequency of the STA dropping corresponding to the AP is 0.058 when a plurality of times (e.g., 100 times) occur. Subsequently, after the actual detection, the operator finds that the STA of this type (i.e., the STA with the dropped connection frequency of 0.058) is actually in the weak coverage area, and then the operator may update the first decision information, i.e., update the first decision information to 0.058. The second decision information is updated similarly to the first decision information, which is not described herein again. Therefore, the accuracy and the reliability of the mathematical model for AP division are further improved.
In addition, as described above, the mathematical model performs type division (i.e., division into weak coverage APs or strong coverage APs) on the APs according to the first decision information corresponding to the dropped frequency and the second decision information corresponding to the roaming frequency, 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:
fig. 4 is a schematic flow chart of a wireless signal coverage detection method in the embodiment of the present application, where in fig. 4:
before describing the training method in the embodiment of the present application, a training scenario in the embodiment of the present application is first described with reference to the drawings. Fig. 5 is a schematic diagram of a training scenario in the embodiment of the present application. Specifically, in the embodiment of the present application, the training scene may be any space such as a room, a plurality of APs are disposed in the room, and the AP disposition mode may be as shown in fig. 5. In the embodiment of the present application, the AP deployment manner shown in fig. 5 is only a suitable example, and an object of the AP deployment manner is to enable signal coverage of multiple APs to cover a whole room, that is, an operator may manually detect signal coverage of the whole room after deploying the APs to determine that there is no signal coverage hole in the room, and a specific manual detection method may refer to an existing technical solution and is not described herein again. Referring to fig. 5, the training scenario includes AP1-4 (AP 1, AP2, AP3, AP4, respectively) and STA1-5 (STA 1, STA2, STA3, STA4, STA5, respectively). In the specific implementation process of the embodiment of the application, the STA may be a computer, a smart phone, or other devices. It should be noted that, in practical applications, the number of the STAs and the APs may be one or more, and the number and the distribution manner of the STAs and the APs in the training scenario shown in fig. 5 are only schematic examples, which is not limited in this application.
In step 401, weak coverage areas are constructed.
Specifically, in the embodiment of the present application, each AP in the training scenario may be controlled by the controller to be respectively turned off, or two or more APs may be turned off simultaneously to construct a weak coverage area, that is, the original signal coverage area of the turned-off AP may be partially or entirely the weak coverage area. It should be noted that, the controller stores in advance the correspondence between the identification information of the AP and the location information, that is, the controller may obtain the specific location of the weak coverage area by closing the AP.
The following describes the process of constructing the weak coverage area in the training scenario in detail with reference to fig. 5:
the controller may sequentially turn off the AP1 and obtain the number of dropped calls and roaming times of the STAs recorded by the AP2-4 within a predetermined time period (e.g., 1 hour) of turning off the AP 1. The specific obtaining step is similar to that in scenario one, and is not described herein again. Then, the controller opens the AP1, closes the AP2, and obtains the number of times of dropped calls and roaming times of each STA recorded by the AP1, the AP3, and the AP4 within a predetermined time, and so on, and closes the AP3 and the AP4, respectively.
This step is the same as step 201 in scenario one, and is not described herein again.
In step 403, the wireless signal coverage detection device determines decision information based on the signal quality information.
Specifically, in the embodiment of the present application, after the controller closes the AP, it may be determined that the location of the AP is a weak coverage area. With this feature, the manner of obtaining the decision information may be: the worst signal quality information (for example, the maximum dropped frequency) of the signal quality information of all STAs recorded by each AP except the closed AP is detected, and the corresponding STA is the STA in the weak coverage area and is the target STA in the embodiment of the present application. Then, the system may confirm that the best quality signal quality information among the signal quality information recorded by the target STA in the record in each AP is the selected signal quality information of the target STA. For example, the following steps are carried out: if the maximum value of the dropped frequency is detected to be 0.96 in the record of each AP, STA1 corresponding to the maximum value of the dropped frequency is recorded as a target STA, and the record of STA1 in each AP is detected, and it is confirmed that STA1 is the target STA, the area where STA1 is located is a weak coverage area, so that all APs include the signal quality information of STA1, that is, the AP of the dropped frequency value is the AP including the weak coverage area, and the minimum value of the dropped frequency corresponding to STA1 in the record of the AP of the dropped frequency recorded with STA1 is the judgment information corresponding to the dropped frequency. The following will explain details of the present invention by way of specific examples.
Specifically, referring to fig. 5, taking the AP1 as an example of being turned off, after the controller turns off the AP1, the shaded portion shown in fig. 5 may be determined as a weak coverage area. Within a predetermined time, assume that the dropped frequency of STA1 recorded by AP2 is 0.06, and the roaming frequency is 0.14; the disconnection frequency of the STA2 is 0, and the roaming frequency is 0; the dropped frequency of STA5 is 0.03 and the roaming frequency is 0.08. The off-line frequency of the STA1 recorded by the AP3 is 0.062, and the roaming frequency is 0.15; the disconnection frequency of the STA3 is 0, and the roaming frequency is 0; the dropped frequency of STA5 is 0.03 and the roaming frequency is 0.09. The off-line frequency of the STA4 recorded by the AP4 is 0, and the roaming frequency is 0; the dropped frequency of the STA5 is 0.03, and the roaming frequency is 0.09 (wherein, the reason why the record of the AP for a part of the STAs is 0 may be that the distance from the AP to the STA is relatively long, and therefore, the signal coverage of the AP cannot cover the area where the STA is located, and therefore, the STA cannot access the AP). Therefore, when the first decision information is set, since the controller confirms that the shaded area is a weak coverage area, and it is known from the above-mentioned record that the STA corresponding to the maximum value of the dropped frequency (i.e., 0.062) is STA1 and the STA corresponding to the maximum value of the roaming frequency (0.15) is STA1, it can be confirmed that STA1 is in the weak coverage area. Therefore, the first decision information and the second decision information may be set as the minimum value of the dropped frequency and the minimum value of the roaming frequency of the STA1 recorded in the AP2-AP4 (i.e., the signal quality information with the best quality in the signal quality information of the STA 1), respectively, that is, the first decision information is 0.06, and the second decision information is 0.14. Then, the controller updates the first decision information and the second decision information according to other constructed weak coverage scenarios, for example, values recorded in the weak coverage scenario constructed after the AP2 is turned off. That is, if the dropped frequency and/or roaming frequency of the STA in the weak coverage area is lower than the set first decision information and second decision information, the first decision information and second decision information are updated. In an embodiment of the present application, the method for updating the decision information may be: when the system determines that the specific value of the newly acquired selected signal quality information is smaller than the specific value of the corresponding decision information, the operator may determine again whether the STA corresponding to the newly acquired selected signal quality information is actually in the weak coverage area, but not for other reasons, for example, caused by STA performance bottleneck. And after confirmation, the system replaces the original decision information with the newly acquired selected signal quality information.
In an embodiment, the controller may not update the decision information each time, but sets the first decision information and the second decision information based on the values recorded by all APs in the training scene, and the specific setting steps are similar to the above and are not described herein again.
Then, the operator may modify the layout of the training scene, including the area size of the training scene, the number and distribution positions of the APs and the STAs, and divide the APs in the training scene according to the first decision information and the second decision information, where the specific division step may refer to the step in the first scene, and is not repeated here. In the training process, the controller can determine the position of the weak coverage area, so the controller can update the first decision information and/or the second decision information according to the position of the weak coverage area, and the currently counted offline frequency and roaming frequency of the STA. Specifically, in another training scenario, after the controller respectively closes each AP, the line drop frequency of the STA appearing in the obtained record is 0.059, and the roaming frequency is 0.016. And, the controller confirms that the recording occurs, the STA is in an area that the closed AP has covered, i.e., a 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 application, an operator can train the mathematical model by setting a large number of training scenes so as to optimize the mathematical model, and therefore the accuracy and the reliability of the classification result of the AP classified by the mathematical model are improved.
In addition, in the embodiment of the present application, in the training process of the mathematical model, the STA may be divided by introducing the uplink negotiation rate counter value, the downlink negotiation rate counter value, the delay counter value and/or the jitter contrast value as described above, that is, whether the STA is a weak STA is determined, so that interference of a hardware problem of the STA on the determination information confirmed by the AP may be eliminated. For example, when the dropped frequency of the STA recorded by the AP is high, but the uplink rate contrast value and the downlink rate contrast value corresponding to the STA are both very low, it may be determined that the reason for causing the phenomenon that the dropped frequency and the roaming frequency of the STA are high may be caused by hardware abnormality of the STA itself. Then, the analysis module may further determine whether there is a weak coverage area in the signal coverage of the AP through the relevant records of other STAs.
To sum up, in the technical scheme in the embodiment of the present application, a weak coverage environment is constructed by closing one or more APs, so as to acquire corresponding decision information, and enable the system to detect whether the STA is in a weak coverage area or not, or whether the weak coverage area exists in a test area or not, so as to implement automatic detection of the weak coverage area of the area, that is, a simple and convenient test method for a signal coverage condition is provided, so as to effectively reduce labor cost and improve test efficiency and accuracy.
