Description

Technical Field

[0001] The embodiments of the present application relate to the field of communications, and in particular to a power configuration method and device. Background Art

[0002] With the development of wireless local area networks (WLANs), the deployment of access points (APs) in WLAN scenarios has become increasingly dense. Dense APs can be managed uniformly through centralized access control (AC) equipment. The power of an AP can be freely configured. However, if the power configured for the AP is too low, the WLAN signal quality provided by the AP will be poor. If the power configured for the AP is too high, severe co-channel interference will occur. Therefore, it is very important to properly configure the power of the AP. The current AP power configuration method is to adjust the power of the AP with the goal of controlling the co-channel interference generated by the AP to the surrounding APs to an allowable level. This adjustment method may result in weak WLAN signal quality provided by the AP to the terminal, and the power adjustment solution will not be ideal. Summary of the Invention

[0003] The embodiments of the present application provide a power configuration method and apparatus, which help to improve the effect of AP power adjustment, so that the AP can provide the terminal with signal quality that meets the requirements.

[0004] A first aspect of the present application provides a power configuration method:

[0005] In a WLAN application scenario, a first AP can provide a WLAN signal to a first terminal, and the first AP can also obtain a first data set including data representing the WLAN signal provided by the first AP to the first terminal. The first network device receives the first data set sent from the first AP, and the first data set includes data used to represent the signal quality provided by the first AP to the first terminal. The first network device can obtain a power parameter based on the first data set, and the power parameter can be used to adjust the WLAN signal quality provided by the first AP; the first network device sends the power parameter to the first AP.

[0006] In an embodiment of the present application, the first network device can obtain power parameters based on the first data set and perform power adjustment based on the quality of the WLAN signal provided by the first AP to the first terminal, which helps to improve the effect of AP power adjustment and enables the AP to provide the terminal with signal quality that meets the requirements.

[0007] In one possible implementation, after receiving the first data set, the first network device obtains the first data based on the adjustment coefficient and the first data set. Then, the first network device can obtain the power parameter based on the first data, the working power of the first AP and the preset signal quality. Specifically, the first network device can determine the path loss based on the first data and the working power of the first AP, and then sum the path loss with the preset signal quality to obtain the power parameter.

[0008] In the embodiment of the present application, a specific method for the first network device to obtain the power parameter according to the first data set is defined, thereby improving the feasibility of the solution.

[0009] In one possible implementation, the first network device may be an AC, and the second network device may be a server or a controller. After the first network device obtains the first data, the first network device may also send the first data to the second network device. The second network device determines the path loss based on the first data and the working power of the first AP, and then sums the path loss with the preset signal quality to obtain the power parameter. The first network device then receives the power parameter from the second network device.

[0010] In the embodiment of the present application, the first network device can send the first data to the second network device, and the second network device obtains the power parameter, thereby reducing the workload of the first network device.

[0011] In one possible implementation, on the basis of receiving a first data set from a first AP, the first network device may also receive a second data set from the first AP, where the second data set includes data for indicating the signal quality provided by the second AP to the first terminal, and the second AP is a neighboring AP of the first AP. The first network device then obtains second data from the second data set, where the second data corresponds to the best signal quality provided by the second AP to the second terminal in the second data set, and the second data corresponds to a first timestamp, which is used to identify the moment when the second data is measured and obtained. The first network device then obtains third data based on the first timestamp and the first data set, where the time when the third data is measured and obtained is consistent with the first timestamp. The first network device may compare the second data with the third data, and update the first data set if the signal quality corresponding to the second data is better than the signal quality corresponding to the third data. The updated first data set does not include the third data, and the first network device then obtains power parameters based on the updated first data set.

[0012] In the embodiment of the present application, after the first network device updates the first data set, it obtains the power parameter based on the first data set, further improving the effect of AP power adjustment, and enabling the AP to provide the terminal with signal quality that meets the requirements.

[0013] In one possible implementation, based on receiving a first data set from a first AP, the first network device also receives a third data set and a fourth data set from a second AP, wherein the third data set includes data for indicating the signal quality provided by the second AP to the second terminal, and the fourth data set includes data for indicating the signal quality provided by the first AP to the second terminal. Subsequently, the first network device obtains fifth data based on the fourth data set, where the fifth data is data corresponding to the best signal quality in the fourth data set, and the fifth data indicates data corresponding to the signal quality provided by the first AP to the second terminal. The fifth data corresponds to a second timestamp, and the second timestamp is used to identify the moment when the fifth data is measured and obtained. The first network device can also obtain sixth data based on the third data set and the above-mentioned second timestamp, where the sixth data is data on the signal quality provided by the second AP to the second terminal in the third data set, and the moment when the sixth data is measured and obtained is the same as the second timestamp. If the signal quality corresponding to the fifth data is better than the signal quality corresponding to the sixth data, the first network device updates the first data set, and the updated first data set also includes the fifth data. Subsequently, the first network device obtains the power parameter according to the updated first data set.

[0014] In the embodiment of the present application, after the first network device updates the first data set, it obtains the power parameter based on the first data set, further improving the effect of AP power adjustment, and enabling the AP to provide the terminal with signal quality that meets the requirements.

[0015] In one possible implementation, on the basis of receiving a first data set from a first AP, the first network device also receives a second data set from the first AP and a third data set and a fourth data set from a second AP, the second data set including data for indicating the signal quality provided by the second AP to the first terminal, the second AP being a neighboring AP of the first AP, the third data set including data for indicating the signal quality provided by the second AP to the second terminal, the fourth data set including data for indicating the signal quality provided by the first AP to the second terminal, and then the first network device obtains second data from the second data set, the second data being data corresponding to the best signal quality provided by the second AP to the second terminal in the second data set, and the second data corresponds to a first timestamp, the first timestamp being used to identify the moment of measuring and obtaining the second data, and then the first network device obtains third data based on the first timestamp and the first data set, the time at which the third data is measured and obtained being the same as the time at which the third data is measured and obtained. A timestamp is consistent, and the first network device obtains fifth data based on the fourth data set. The fifth data is data corresponding to the best signal quality in the fourth data set, and the fifth data is data corresponding to the signal quality provided by the first AP to the second terminal. The fifth data corresponds to the second timestamp, and the second timestamp is used to identify the moment of measuring and obtaining the fifth data. The first network device can also obtain sixth data based on the third data set and the above-mentioned second timestamp. The sixth data is data on the signal quality provided by the second AP to the second terminal in the third data set. The moment of measuring and obtaining the sixth data is the same as the second timestamp. If the signal quality corresponding to the second data is better than the signal quality corresponding to the third data, and the signal quality corresponding to the fifth data is better than the signal quality corresponding to the sixth data, the first network device updates the first data set. The updated first data set does not include the third data, and the first data set also includes the fifth data. Afterwards, the first network device obtains the power parameter according to the updated first data set.

[0016] In the embodiment of the present application, after the first network device updates the first data set, it obtains the power parameter based on the first data set, further improving the effect of AP power adjustment, and enabling the AP to provide the terminal with signal quality that meets the requirements.

[0017] In one possible implementation, after the first network device updates the first data set, it obtains fourth data based on the adjustment coefficient and the updated first data set. Thereafter, the first network device obtains a power parameter based on the fourth data, the working power of the first AP, and a preset signal quality. Specifically, the first network device can determine the path loss based on the first data and the working power of the first AP, and then sum the path loss with the preset signal quality to obtain the power parameter.

[0018] In the embodiment of the present application, a method for the first network device to obtain the power parameter according to the updated first data set is defined, thereby improving the feasibility of the solution.

[0019] In one possible implementation, after the first network device obtains the fourth data based on the updated first data set, it sends the fourth data to the second network device. The second network device determines the path loss based on the first data and the operating power of the first AP, and then sums the path loss with the preset signal quality to obtain the power parameter. After that, the first network device receives the power parameter from the second network device.

[0020] In the embodiment of the present application, the first network device can send the fourth data to the second network device, and the second network device obtains the power parameter, thereby reducing the workload of the first network device.

[0021] A second aspect of the present application provides a power configuration device, which is provided in the first network device in the first aspect or any possible implementation of the first aspect.

[0053] The embodiments of the present application provide a method and apparatus for power configuration, which are used to ensure that the power configured for an access point (AP) can meet the communication quality requirements of a terminal.

[0054] The power configuration method in the embodiment of the present application can be applied to the communication scenario of wireless local area network (WLAN). Figure 1In a WLAN communication scenario, a terminal accesses the network by connecting to an AP. Multiple terminals can connect to one AP. A terminal can report data to the AP indicating the quality of the WLAN signal received by the terminal. This data can include the WLAN signal provided by the AP to the terminal, as well as WLAN signals provided by APs deployed around the AP. Because many APs may be deployed in a WLAN communication scenario, a centralized access control (AC) is required to uniformly manage the APs in the WLAN communication scenario. The AC can distribute configurations to different APs in the WLAN communication scenario, manage radio resources, and control user access.

[0055] See also Figure 2 , the following describes a process of the power configuration method according to an embodiment of the present application:

[0056] 201. A first network device receives a first data set from a first AP;

[0057] In a WLAN application scenario, a first network device may receive a first data set from a first AP, where the first data set includes data for indicating the quality of a WLAN signal provided by the first AP to a first terminal. The first terminal may be a terminal connected to the first AP. It should be noted that the first terminal needs to support the 802.11k protocol. The first terminal may include multiple terminals. For each first terminal, the first data set also includes data on the quality of the WLAN signal provided by the first AP to the terminal at different times. Specifically, the type of data in the first data set may be downlink signal strength, or may be a path loss value, which is not specifically limited here. It is understandable that the power configuration method of the embodiment of the present application is based on big data analysis, so the amount of data in the first data set needs to meet a preset amount, and the number of first terminals also needs to meet a preset amount.

[0058] It should be noted that the first network device can be an AC, or the first network device can also be a server, or the first network device can also be a controller. The specific details are not limited here. When the first network device is a server or a controller, the first network device can receive the first data set from the first AP in the same way as the first network device receives the first data set from the AC. The first data set is the first data set received by the AC from the first AP.

[0059] 202. The first network device obtains a power parameter based on the first data set;

[0060] After receiving the first data set, the first network device obtains a power parameter based on the first data set. The power parameter is the operating power configured for the first AP. Since the operating power of the first AP is related to the quality of the WLAN signal provided by the first AP, the power parameter can be used to adjust the quality of the WLAN signal provided by the first AP.

[0061] 203. The first network device sends a power parameter to the first AP.

[0062] After determining the power parameter, the first network device sends the power parameter to the first AP. After receiving the power parameter, the first AP operates according to the power parameter.

[0063] In the embodiment of the present application, the first network device can determine the power parameter based on the quality of the WLAN signal provided by the first AP to the first terminal, which helps to improve the effect of AP power adjustment so that the AP can provide the terminal with signal quality that meets the requirements.

[0064] The above describes a process of the power configuration method of the embodiment of the present application. Figure 3 , below in the above Figure 2 Based on the illustrated embodiment, a process of the first network device acquiring the power parameter based on the first data set is described in detail:

[0065] Step 301 of this embodiment is similar to step 201 of the above embodiment, and will not be described in detail here.

[0066] 302. The first network device obtains first data based on the adjustment coefficient and the first data set;

[0067] Taking the first data set including 10 downlink signal strength data as an example, the 10 downlink signal strength data are arranged in descending order as follows: -68dBm (decibel-milliwatt), -70dBm, -72dBm, -74dBm, -76dBm, -78dBm, -80dBm, -82dBm, -84dBm and -86dBm. After receiving the first data set, the first network device obtains an adjustment coefficient from the local configuration. For example, the adjustment coefficient obtained by the first network device from the local configuration is 90%. The first network device can then obtain the first data based on the adjustment coefficient and the first data set. Specifically, the first data is the Nth data in the first data set arranged from large to small according to the quality of the WLAN signal, where N is the product of the adjustment coefficient and the number of data in the first data set. Taking the above data as an example, N is 10 multiplied by 90%, that is, N is 9, then the first data is the 9th data in the first data set arranged from large to small according to the quality of the WLAN signal, that is, the first data is the downlink signal strength of -84dBm.

[0068] 303. The first network device obtains a power parameter based on the first data, the operating power of the first AP, and a preset signal quality.

[0069] The first network device can obtain the current working power of the first AP. Taking the current working power of the first AP as 5 as an example, the first network device can then use Formula 1 to calculate the path loss value corresponding to the first data based on the first data and the working power of the first AP. According to Formula 1, the path loss value corresponding to the first data is 5dBm-(-84dBm)=89dB (decibel, deciBel), and the power parameter is the sum of the above path loss value and the expected signal quality. In the embodiment of the present application, the unit of path loss is dB, while the unit of signal quality and power parameters is dBm. It should be noted that the preset signal quality is the quality of the WLAN signal expected to be provided by the first AP to the terminal in the actual WLAN application scenario. Taking the preset signal quality of -65dBm as an example, the power parameter is (-65dBm)+89dB=24dBm.

[0070] Formula 1

[0071] Downlink signal strength = operating power - path loss

[0072] 304. The first network device sends a power parameter to the first AP.

[0073] After determining the power parameter, the first network device sends the power parameter to the first AP. After receiving the power parameter, the first AP operates according to the power parameter.

[0074] It should be noted that when the first network device is a server or a controller, the first network device may send the power parameter to the first AP by sending the power parameter to the AC, and after receiving the power parameter, the AC sends the power parameter to the first AP.

[0075] In the embodiment of the present application, a method in which the first network device obtains the first data based on the adjustment coefficient and the first data set is limited, thereby improving the feasibility of the solution.

[0076] The above describes a solution in which the first network device obtains the power parameter based on the first data. In actual applications, the first network device can also obtain the power parameter by sending the first data to the second network device. Figure 4 , the following is a detailed introduction:

[0077] In this embodiment, steps 401 to 402 are the same as those in the above Figure 3 In the illustrated embodiment, steps 301 to 302 are similar and will not be described in detail here.

[0078] 403. The first network device sends first data to the second network device.

[0079] After determining the first data, the first network device sends the first data to the second network device. It should be noted that, in this embodiment, the first network device may be an AC, and the second network device may be a server or a controller.

[0080] 404. The second network device obtains a power parameter based on the first data, the operating power of the first AP, and a preset signal quality.

[0081] In step 404 of this embodiment, the second network device obtains the power parameter based on the first data, the working power of the first AP and the preset signal quality in the same manner as described above. Figure 3 The steps in step 303 in the illustrated embodiment are similar and will not be described again here.

[0082] 405. The first network device receives a power parameter from the second network device.

[0083] After receiving the first data from the first network device, the second network device can determine the power parameter according to the first data. The specific determination method is the same as the above Figure 3 Step 303 in the illustrated embodiment is similar and will not be described again here.

[0084] 406. The first network device sends a power parameter to the first AP.

[0085] After acquiring the power parameter, the first network device sends the power parameter to the first AP. After receiving the power parameter, the first AP operates according to the power parameter.

[0086] In the embodiment of the present application, the first network device can obtain the power parameter by sending the first data to the second network device, thereby reducing the workload of the first network device.

[0087] The above describes how the first network device obtains the power parameter based on the first data set from the first AP. In actual applications, the first network device can obtain the power parameter based on the first data set and the second data set from the first AP. Figure 5 , the following is a detailed introduction:

[0088] 501. A first network device receives a first data set and a second data set from a first AP;

[0089] A first network device receives a first data set and a second data set from a first AP, wherein the second data set includes data indicating the quality of a WLAN signal provided by the second AP to a first terminal. The second AP is a neighboring AP of the first AP and may include multiple APs. The second data set includes data indicating the quality of the WLAN signal provided by the second AP to the first terminal at different times. Specifically, the type of data in the second data set may be downlink signal strength or path loss value, which is not limited herein. It is understood that the power configuration method of the embodiment of the present application is based on big data analysis, and therefore the amount of data in the second data set must meet a preset amount. It should be noted that the first network device may be an AC, a server, or a controller, which is not limited herein. When the first network device is a server or a controller, the first network device may receive the first data set from the first AP in the manner in which it receives the first data set from the AC, where the first data set is the first data set received by the AC from the first AP.

[0090] 502. The first network device obtains a first timestamp and second data corresponding to the first terminal based on the second data set;

[0091] After the first network device obtains the second data set, it can obtain second data based on the second data set, where the second data corresponds to the first timestamp and is data in the second data set corresponding to the quality of the best WLAN signal provided by the second AP to the first terminal. Taking the first data set including 11 downlink signal strength data as an example, the 11 downlink signal strength data are arranged in descending order as follows: -70dBm, -70dBm, -72dBm, -74dBm, -76dBm, -78dBm, -80dBm, -82dBm, -84dBm, -86dBm and -88dBm. Taking the second data set including 10 downlink signal strength data as an example, the 10 downlink signal strength data are arranged in descending order as follows: -99dBm, -98dBm, -97dBm, -96dBm, -95dBm, -94dBm, -93dBm, -92dBm, -90dBm and -87dBm. Each data in the first data set and the second data set has a corresponding MAC address. And a timestamp, the MAC address is the MAC address of the terminal corresponding to the data, the timestamp is used to identify the moment when the data is measured, each data in the second data set can correspond to the same timestamp and MAC address, and each data in the second data set can also correspond to a different timestamp and MAC address. The specific details are not limited here. In a preferred manner, each data in the second data set corresponds to the same timestamp and MAC address. For example, the data in the second data set all corresponds to the first timestamp and MAC address 1. It can be understood that the second data set can also include multiple data sets, and accordingly, the second data can also include multiple data. For the sake of simplicity of description, this embodiment only takes one second data set as an example for description. Therefore, taking the above data as an example, the first network device can obtain the second data as -87dBm.

[0092] 503. The first network device obtains third data based on the first timestamp and the first data set.

[0093] After obtaining the second data, the first network device obtains the third data in the first data set based on the first timestamp and MAC address 1 corresponding to the second data. The third data corresponds to the first timestamp and MAC address 1. For example, in the first data set, the downlink signal strength data -88dBm corresponds to the first timestamp and MAC address 1, then the first network device can determine the downlink signal strength data -88dBm as the third data.

[0094] 504. When the signal quality corresponding to the second data is better than the signal quality corresponding to the third data, the first network device updates the first data set.

[0095] The first network device can compare the obtained second data and third data. If the signal quality corresponding to the second data is better than the signal quality corresponding to the third data, it means that at the same time, the quality of the WLAN signal provided by the first AP to the first terminal corresponding to MAC address 1 is weaker than that provided by the second AP to the first terminal corresponding to MAC address 1. Taking the above data as an example, the second data -87dBm is greater than the third data -88dBm, which proves the existence of stickiness. Therefore, the first network device updates the first data set. The updated first data set does not include the third data. Taking the above data as an example, the updated first data set does not include the downlink signal strength data -88dBm. Therefore, the updated first data set is -70dBm, -70dBm, -72dBm, -74dBm, -76dBm, -78dBm, -80dBm, -82dBm, -84dBm and -86dBm.

[0096] 505. The first network device obtains fourth data based on the adjustment coefficient and the updated first data set;

[0097] Taking the adjustment coefficient as 90% as an example, the first network device may obtain the fourth data in the updated first data set as -84.

[0098] 506. The first network device obtains a power parameter based on the fourth data, the working power of the first AP, and a preset signal quality.

[0099] After determining the fourth data, the first network device obtains the power parameter based on the fourth data, the working power of the first AP and the preset signal quality. The specific acquisition method is the same as above. Figure 3 Step 303 in the illustrated embodiment is similar and will not be described in detail here.

[0100] 507. The first network device sends a power parameter to the first AP.

[0101] It should be noted that when the first network device is a server or a controller, the first network device may send the power parameter to the first AP by sending the power parameter to the AC, and after receiving the power parameter, the AC sends the power parameter to the first AP.

[0102] In the embodiment of the present application, the first network device obtains the power parameter according to the first data set and the second data set, which helps to improve the effect of AP power adjustment, so that the AP provides the terminal with signal quality that meets the requirements.

[0103] The above describes a process for obtaining power parameters based on the first data set and the second data set from the first AP. In actual implementation, the first network device can also obtain power parameters by sending the fourth data to the second network device. Figure 6 , the following is a detailed introduction:

[0104] In this embodiment, steps 601 to 605 are the same as those in the above Figure 5 In the illustrated embodiment, steps 501 to 505 are similar and will not be described in detail here.

[0105] 606. The first network device sends fourth data to the second network device.

[0106] After determining the fourth data, the first network device sends the fourth data to the second network device. After receiving the fourth data, the second network device obtains the power parameter according to the fourth data, the working power of the first AP and the preset signal quality. The specific acquisition method is the same as above. Figure 3 Step 303 in the illustrated embodiment is similar and will not be described in detail here.

[0107] It should be noted that, in this embodiment, the first network device may be an AC, and the second network device may be a server or a controller.

[0108] 607. The second network device obtains a power parameter based on the fourth data, the working power of the first AP, and a preset signal quality.

[0109] After determining the fourth data, the second network device obtains the power parameter based on the fourth data, the working power of the first AP and the preset signal quality. The specific acquisition method is the same as the above Figure 3 Step 303 in the illustrated embodiment is similar and will not be described in detail here.

[0110] 608. The first network device receives the power parameter from the second network device.

[0111] After acquiring the power parameter, the second network device sends the power parameter to the first network device.

[0112] 609. The first network device sends a power parameter to the first AP.

[0113] After acquiring the power parameter, the first network device sends the power parameter to the first AP. After receiving the power parameter, the first AP operates according to the power parameter.

[0114] In the embodiment of the present application, the first network device may also send fourth data to the second network device to obtain power parameters, thereby reducing the workload of the first network device.

[0115] The above describes a method in which the first network device obtains the power parameter based on the first data set and the second data set from the first AP. In actual implementation, the first network device may also obtain the power parameter based on the first data set from the first AP and the third data set and the fourth data set from the second AP. Figure 7 , described in detail below:

[0116] 701. A first network device receives a first data set from a first AP and a third data set and a fourth data set from a second AP;

[0117] A first network device receives a first data set from a first AP and a third data set and a fourth data set from a second AP, wherein the third data set includes data indicating the quality of the WLAN signal provided by the second AP to a second terminal, where the second terminal is a terminal connected to the second AP. It should be noted that the second terminal needs to support the 802.11k protocol, and the second terminal may include multiple terminals. For each second terminal, the third data set also includes data indicating the quality of the WLAN signal provided by the second AP to the terminal at different times. The fourth data set includes data indicating the quality of the WLAN signal provided by neighboring APs of the second AP to the second terminal, where the neighboring APs also include the first AP. Specifically, the type of data in the third data set and the fourth data set can be downlink signal strength or path loss value, which is not specifically limited here. It will be understood that the power configuration method of the embodiment of the present application is based on big data analysis, and therefore the amount of data in the third data set and the fourth data set needs to meet a preset number, and the number of second terminals also needs to meet a preset number.

[0118] It should be noted that the first network device can be an AC, or the first network device can also be a server, or the first network device can also be a controller. The specific details are not limited here. When the first network device is a server or a controller, the first network device can receive the first data set from the first AP in the same way as the first network device receives the first data set from the AC. The first data set is the first data set received by the AC from the first AP.

[0119] 702. The first network device obtains a second timestamp and fifth data corresponding to the second terminal based on the fourth data set.

[0120] The first network device can obtain fifth data based on the fourth data set, where the fifth data corresponds to the second timestamp, and the fifth data is the data corresponding to the quality of the WLAN signal provided by the first AP to the second terminal in the third data set, and the fifth data is the data corresponding to the quality of the best WLAN signal in the fourth data set. Taking the third data set including 9 downlink signal strength data as an example, the 9 downlink signal strength data are arranged in descending order as follows: -72dBm, -74dBm, -76dBm, -78dBm, -80dBm, -82dBm, -84dBm, -86dBm and -88dBm. Taking the fourth data set including 10 downlink signal strength data as an example, the 10 downlink signal strength data are arranged in descending order as follows: -98dBm, -97dBm, -97dBm, -96dBm, -95dBm, -94dBm, -93dBm, -92dBm, -90dBm and -87dBm. Each data in the third data set and the fourth data set has a corresponding MAC address and timestamp. The C address is the MAC address of the terminal corresponding to the data, and the timestamp is used to identify the moment when the data is measured. Each data in the fourth data set can correspond to the same timestamp and MAC address, and each data in the fourth data set can also correspond to a different timestamp and MAC address. The specific details are not limited here. In a preferred manner, each data in the fourth data set corresponds to the same timestamp and MAC address. For example, the data in the fourth data set all corresponds to the second timestamp and MAC address 2. It can be understood that the fourth data set can also include multiple data sets, and accordingly, the fifth data can also include multiple data. For the sake of simplicity of description, this embodiment only takes one fourth data set as an example for description. Therefore, taking the above data as an example, the first network device can obtain the fifth data as -87dBm.

[0121] 703. The first network device obtains sixth data based on the third data set and the second timestamp.

[0122] After obtaining the fifth data, the first network device determines the sixth data corresponding to the second timestamp and MAC address 2 in the third data set based on the second timestamp and MAC address 2 corresponding to the fifth data. For example, in the third data set, the downlink signal strength data -88dBm corresponds to the second timestamp and MAC address 2, and therefore the downlink signal strength data -88dBm is determined to be the sixth data.

[0123] 704. When the signal quality corresponding to the fifth data is better than the signal quality corresponding to the sixth data, the first network device updates the first data set.

[0124] After obtaining the fifth data and the sixth data, the first network device can compare the fifth data and the sixth data. If the signal quality corresponding to the fifth data is better than the signal quality corresponding to the sixth data, the first network device updates the first data set. Taking the above data as an example, the signal quality corresponding to the fifth data -87dBm is greater than the signal quality corresponding to the sixth data -88dBm, indicating that at the same time, the quality of the WLAN signal provided by the first AP to the second terminal corresponding to MAC address 2 is greater than the quality of the WLAN signal provided by the second AP to the above terminal, proving the existence of a sticky phenomenon. Therefore, the first network device will update the first data set, and the updated first data set also includes the fifth data. Taking the above data as an example, the updated first data set is: -72dBm, -74dBm, -76dBm, -78dBm, -80dBm, -82dBm, -84dBm, -86dBm, -87dBm and -88dBm.

[0125] 705. The first network device obtains fourth data based on the adjustment coefficient and the updated first data set;

[0126] After obtaining the updated first data set, the first network device obtains fourth data based on the adjustment coefficient and the updated first data set. Taking the adjustment coefficient as 90% as an example, the fourth data obtained may be -87dBm.

[0127] 706. The first network device obtains a power parameter based on the fourth data, the operating power of the first AP, and a preset signal quality.

[0128] After determining the fourth data, the first network device obtains the power parameter based on the fourth data, the working power of the first AP and the preset signal quality. The specific acquisition method is the same as above. Figure 3 Step 303 in the illustrated embodiment is similar and will not be described in detail here.

[0129] 707. The first network device sends a power parameter to the first AP.

[0130] After acquiring the power parameter, the first network device sends the power parameter to the first AP.

[0131] It should be noted that when the first network device is a server or a controller, the first network device may send the power parameter to the first AP by sending the power parameter to the AC, and after receiving the power parameter, the AC sends the power parameter to the first AP.

[0132] In the embodiment of the present application, the first network device can determine the power parameter based on the first data set, the third data set and the fourth data set, which helps to improve the effect of AP power adjustment, so that the AP provides the terminal with signal quality that meets the requirements.

[0133] The above describes a process for the first network device to determine the power parameter based on the first data set, the third data set, and the fourth data set. Figure 8 , another process for the first network device to determine the power parameter according to the first data set, the third data set, and the fourth data set is described below:

[0134] In this embodiment, steps 801 to 805 are the same as those in the above Figure 7 In the illustrated embodiment, steps 701 to 705 are similar and will not be described in detail here.

[0135] 806. The first network device sends fourth data to the second network device.

[0137] 807. The second network device obtains a power parameter based on the fourth data, the working power of the first AP, and a preset signal quality.

[0138] After determining the fourth data, the second network device obtains the power parameter based on the fourth data, the working power of the first AP and the preset signal quality. The specific acquisition method is the same as the above Figure 3 Step 303 in the illustrated embodiment is similar and will not be described in detail here.

[0139] 808. The first network device receives a power parameter from the second network device.

[0140] After the second network device receives the fourth data, it determines the power parameter according to the fourth data, the working power of the first AP and the preset signal quality. The specific acquisition method is the same as above. Figure 3 Step 303 in the illustrated embodiment is similar and will not be described again here.

[0141] 809. The first network device sends a power parameter to the first AP.

[0142] After receiving the power parameter from the second network device, the first network device sends the power parameter to the first AP. After receiving the power parameter, the first AP operates according to the power parameter.

[0143] In the embodiment of the present application, the first network device may also send fourth data to the second network device to obtain power parameters, thereby reducing the workload of the first network device.

[0144] The above describes the manner in which the first network device obtains the power parameter based on the first data set, the third data set, and the fourth data set. In actual implementation, the first network device may also obtain the power parameter based on the first data set, the second data set, the third data set, and the fourth data set. Figure 9 , the following is a detailed introduction:

[0145] 901. A first network device receives a first data set and a second data set from a first AP;

[0146] Step 901 of this embodiment is the same as the above Figure 5 Step 501 in the illustrated embodiment is similar and will not be described again here.

[0147] It should be noted that the first network device can be an AC, or the first network device can also be a server, or the first network device can also be a controller. The specific details are not limited here. When the first network device is a server or a controller, the first network device can receive the first data set from the first AP in the same way as the first network device receives the first data set from the AC. The first data set is the first data set received by the AC from the first AP.

In this embodiment, the second data set includes 10 downlink signal strength quality data as an example. The 10 downlink signal strength quality data are: -99dBm, -98dBm, -97dBm, -96dBm, -95dBm, -94dBm, -93dBm, -92dBm, -90dBm and -87dBm, thereby obtaining the second data of -87, which corresponds to the first timestamp and MAC address 1.

The 10 downlink signal strength data include: -70dBm, -72dBm, -74dBm, -76dBm, -78dBm, -80dBm, -82dBm, -84dBm, -86dBm and -88dBm. Exemplarily, if the downlink signal strength data -88dBm corresponds to the first timestamp and MAC address 1, the first network device obtains the third data, and the third data is the downlink signal strength data -88dBm.

[0154] 905. The first network device obtains a second timestamp and fifth data corresponding to the second terminal based on the fourth data set.

[0155] Step 905 of this embodiment is the same as the above Figure 7 Step 702 in the illustrated embodiment is similar. In this embodiment, the fourth data set includes 10 downlink signal strength data as an example. The 10 downlink signal strength data include: -68dBm, -72dBm, -72dBm, -71dBm, -73dBm, -75dBm, -76dBm, -77dBm, -78dBm and -75dBm. Therefore, the fifth data obtained is -68dBm, which corresponds to the second timestamp and MAC address 2.

[0156] 906. The first network device obtains sixth data based on the third data set and the second timestamp.

[0157] In this embodiment, the third data set includes 10 downlink signal strength data as an example. The 10 downlink signal strength data include: -65dBm, -65dBm, -66dBm, -66dBm, -66dBm, -67dBm, -64dBm, -64dBm, -63dBm and -69dBm. Assuming that the downlink signal strength data -69dBm in the third data set corresponds to the second timestamp and MAC address 2, the first network device obtains the sixth data, that is, the sixth data is -69dBm.

[0158] 907. The first network device updates the first data set when the signal quality corresponding to the second data is better than the signal quality corresponding to the third data, and the signal quality corresponding to the fifth data is better than the signal quality corresponding to the sixth data.

[0159] The signal quality corresponding to the second data -87dBm is better than the signal quality corresponding to the third data -88dBm, and the signal quality corresponding to the fifth data -68dBm is better than the signal quality corresponding to the sixth data -69dBm. At this time, the first network device updates the first data set. The updated first data set does not include the third data, and the updated first data set also includes the fifth data. Taking the above data as an example, the updated first data set is: -68dBm, -70dBm, -72dBm, -74dBm, -76dBm, -78dBm, -80dBm, -82dBm, -84dBm and -86dBm.
