Description

Tuning method, access controller, customer premises equipment and storage medium
Technical Field
The present application relates to the field of wireless network technologies, and in particular, to a tuning method, an access controller (access controller, AC), customer-premises equipment (CPE), and a storage medium.
Background
A Wireless Local Area Network (WLAN) is a widely used access technology, which expands a traditional wired network, can provide a convenient and flexible access service for users, and has good application in the scenes of campuses, markets, office buildings, hotels, industrial parks and the like.
A WLAN system generally includes an AC, a wireless Access Point (AP), and a terminal device, wherein the AC is responsible for centrally controlling a plurality of APs, and the AP is used to provide wireless network signals to the terminal device. In order to improve coverage and quality of wireless network signals, the AC often needs to appropriately adjust channels, bandwidths, transmit power, and the like of the AP, i.e., radio frequency tuning.
The existing radio frequency tuning method comprises the following steps: the signal coverage intensity in the space is detected by manually holding the special terminal, the detected data are sent to the AC, and then the AC adjusts the working state of the AP according to the data. Since this method requires manual intervention, it is difficult to frequently detect the signal coverage intensity, and thus it is only suitable for the start-up phase of the WLAN system. Another method for radio frequency tuning is as follows: the AP simulates the actual signal coverage state of the AP through an algorithm, simulation data are sent to the AC, and then the AC adjusts the working state of each AP according to the data uploaded by each AP. According to the method, simulation data at the AP side is used as a tuning basis, but the simulation data cannot accurately represent actual signal coverage conditions, so that the tuning effect is not good enough.

In a first aspect, the present application provides a tuning method for an AC, the AC controlling a plurality of APs, the method comprising: receiving detection data sent by a CPE, wherein the detection data comprises information of radio frequency signals transmitted by at least one AP in a plurality of APs detected by the CPE; and adjusting the configuration of one or more of the plurality of APs from the first configuration to the second configuration according to the detection data.
It can be seen that the CPE of the present application has a radio frequency signal detection function, and can detect radio frequency signals in its surrounding environment. When the CPE detects a radio frequency signal transmitted by at least one AP under control of the AC, the obtained detection data can be sent to the AC to serve as a basis for the AC to perform radio frequency tuning on the AP under control. Because the CPE exists as a client (STA) for the AP, the detection data obtained by the CPE actually starts from the end side, and the AC uses the signal coverage actually perceived by the end side as a tuning basis, so that the configuration of the AP can be more accurately adjusted. According to the scheme, manual participation is not needed, the labor investment can be saved, the radio frequency tuning can be quickly, conveniently and in real time, the special signal detection terminal is not needed, the signal detection is directly carried out by utilizing the network equipment such as the CPE in the WLAN system, and the radio frequency tuning is realized.
In one possible implementation, the signal quality obtained by the CPE accessing the AP when the configuration of the one or more APs is the second configuration is better than the signal quality obtained by the CPE accessing the AP when the configuration of the one or more APs is the first configuration. That is, the AC may enable the CPE (single CPE) to obtain better signal quality (e.g., higher signal strength, lower signal-to-noise ratio) by adjusting the configuration of the one or more APs.
In one possible implementation, the signal quality obtained by the plurality of CPEs including the CPE accessing the AP when the configuration of the one or more APs is the second configuration is better than the signal quality obtained by the plurality of CPEs accessing the AP when the configuration of the one or more APs is the first configuration.

The AC may perform radio frequency tuning based on the information in the detection data provided by the CPE.
In one possible embodiment, the above detection data further includes: information of radio frequency signals transmitted by other devices than the above-mentioned APs detected by the CPE. That is, the CPE may detect, in addition to radio frequency signals transmitted by one or more APs under AC control, radio frequency signals transmitted by other devices, such as those transmitted by rogue APs or other interfering sources, i.e., interfering signals. The detection data sent to the AC by the CPE may also carry the information of the interference signal, so as to be used as one of the judgment bases for the AC to adjust the AP configuration. The AC may avoid the influence of the above-mentioned interference sources as much as possible by reasonably adjusting the configuration of one or more APs.
In one possible implementation, the above configuration includes one or more of transmit power, channel, and bandwidth.
In one possible implementation manner, the adjusting the configuration of one or more APs in the plurality of APs from the first configuration to the second configuration according to the detection data includes: the AC determining a second configuration of the one or more APs based on the detection data; the AC sends a configuration message to the one or more APs, wherein the configuration message is used to instruct the one or more APs to adjust their configuration from the first configuration to the second configuration.
In this scheme, the AC may determine one or more APs that need to be configured to be adjusted according to the detection data sent by the CPE, and determine a second configuration of the one or more APs. The AC may then complete tuning by sending a configuration message to the one or more APs to adjust the configuration of the one or more APs from the previous first configuration to the second configuration.
In one possible embodiment, the AC may also instruct the CPE to send the detection data to the AC before the AC receives the detection data sent by the CPE. That is, the AC may actively obtain the detection data from the CPE, such as the AC may send an indication to the CPE to upload the detection data at any time or periodically. When the CPE receives an indication of the AC, it can send its own detection data to the AC.
In a second aspect, the present application also provides a tuning method for CPE, the method comprising: the detection data of the CPE is transmitted to the AC such that the AC adjusts the configuration of one or more of the plurality of APs that the AC manages from a first configuration to a second configuration in accordance with the detection data.
In one possible implementation, the signal quality obtained by the CPE accessing the AP when the configuration of the one or more APs is the second configuration is better than the signal quality obtained by the CPE accessing the AP when the configuration of the one or more APs is the first configuration.
In one possible implementation, the signal quality obtained by the plurality of CPEs including the CPE accessing the AP when the configuration of the one or more APs is the second configuration is better than the signal quality obtained by the plurality of CPEs accessing the AP when the configuration of the one or more APs is the first configuration.

In a possible embodiment, before said sending the detection data of the CPE to the AC, the method further comprises: and the CPE receives the detection instruction sent by the AC, and executes radio frequency signal detection according to the detection instruction to obtain the detection data. That is, the AC may actively send a detection instruction to the CPE to instruct the CPE to perform radio frequency signal detection, i.e., the CPE does not actively perform signal detection, and only when the AC needs, the signal detection may be started, which may save energy consumption of the CPE. After receiving the detection instruction of the AC, the CPE can start to execute radio frequency signal detection, obtain corresponding detection data and send the corresponding detection data to the AC as a tuning basis.
In a possible embodiment, before said sending the detection data of the CPE to the AC, the method further comprises: the CPE performs radio frequency signal detection to obtain detection data and stores the detection data; the sending the detection data of the CPE to the AC includes: the CPE receives the query instruction of the AC and sends the self-stored detection data to the AC according to the query instruction.
That is, the CPE may actively perform signal detection without having to begin detection upon receipt of an indication of the AC. For example, the CPE itself may periodically detect the radio frequency signal in its surrounding environment, so as to obtain corresponding detection data, which may be temporarily stored in the memory of the CPE. When the CPE receives the query instruction of the AC, the detection data in the self memory can be directly sent to the AC without consuming time for detection, so that the time for the AC to acquire the detection data of the CPE can be shortened, and the time for the whole tuning process can be shortened.

Detailed Description
In order to facilitate understanding of the technical solution in the embodiments of the present application, a WLAN system according to the embodiments of the present application will be briefly described below.
Referring to fig. 1, fig. 1 is a schematic architecture diagram of a WLAN system according to an embodiment of the present application, where the system includes an AC device 100, an AP device 200, a CPE device 300, and a terminal device 400. These 4 types of devices are each described in detail below.
(1) AC device 100: is responsible for centrally controlling multiple AP devices 200 (fig. 1 is exemplified by AP1 and AP 2). For example, the AC device 100 may implement functions such as configuration issuing of the AP device 200, user authentication, virtual local area network (virtual local area network, VLAN) division, radio frequency resource management, and packet forwarding, which are not particularly limited in the present application.
Communication between AC device 100 and each AP device 200 may be performed using a control and configuration protocol for wireless access points (control and provisioning of wireless access points protocol specification, CAPWAP). The present application is not limited with respect to a specific connection manner between the AP device 200 and the plurality of AP devices 200.
(2) AP apparatus 200: the application is not particularly limited, and is used for realizing the functions of receiving/transmitting wireless signals, converting between wireless signals and wired signals, encrypting and decrypting data and the like. Each AP device 200 may provide a range of wireless signal (e.g., wireless fidelity wireless fidelity, wi-Fi) signal coverage.
(3) CPE device 300: the wireless connection with the AP device 200 may receive the wireless signal transmitted by the AP device 200 and convert the wireless signal into a wired signal, which is provided to one or more terminal devices 400. In other words, the CPE device 300 can convert a wireless network into a wired network, and provide wired network access to the wired terminal device 400 such as a desktop computer, which is equivalent to acting as a wired network interface.
For example, as shown in FIG. 1, the WLAN system includes a plurality of CPE devices 300, CPE1, CPE2 and CPE3, respectively. Each CPE device 300 corresponds to a wireless network card, and is configured to receive a wireless signal transmitted by any AP device 200 and convert the wireless signal into a wired signal; the terminal device 400 which does not have a wireless function can be connected to any CPE device 300 by a wired connection. The same CPE device 300 may provide multiple ports and may be connected to one or more terminal devices 400, not specifically limited.
In a possible embodiment, CPE device 300 includes a System On Chip (SOC), a memory unit, and a protocol stack (including a wired protocol stack and a wireless protocol stack). The SOC is mainly responsible for task scheduling and data forwarding control, and comprises control plane communication and forwarding plane communication of a network, such as data encapsulation and decapsulation, flow forwarding information inquiry and the like; the wired protocol stack and the wireless protocol stack are respectively responsible for implementing the wired protocol and the wireless protocol.
(4) Terminal device 400: terminal devices not having a wireless function cannot be directly networked through the AP device 200. The terminal device 400 may be connected to the CPE device 300 in a wired manner so as to enable network access through the CPE device 300. The terminal device 400 may be a desktop computer, an intelligent production device (such as a chip mounter, an automatic board feeder, a solder paste printer, a reflow soldering device, an automatic optical inspection (automatic optical inspection) device, etc.), an intelligent refrigerator, or an intelligent washing machine, etc., and the present application is not particularly limited.
Based on the above-described various devices in the WLAN system, an embodiment of the tuning method in the present application will be described below.
Referring to fig. 2, fig. 2 is a flow chart of an optimization method provided in an embodiment of the application, which may include the following steps:
S201, the CPE device 300 detects the radio frequency signal in its surrounding environment to obtain detection data.
It should be noted that, because the actions of each CPE device 300 are similar, fig. 2 is directly described by taking one CPE device 300 as an example, but does not represent that only one CPE device 300 may be provided, and that one or more CPE devices 300 may be provided. Similarly, fig. 2 is directly described by taking one AP device 200 as an example, but does not represent that only one AP device 200 is available.
Specifically, each AP device 200 may externally transmit a corresponding radio frequency signal according to its current configuration (current configuration in terms of channel, bandwidth, transmission power, etc.). It will be appreciated that the transmit power of the AP device 200 determines, to a large extent, its signal coverage, the greater the transmit power of the AP device 200, the greater its signal coverage. Of course, the signal coverage of the AP device 200 may also be affected by environmental factors, such as obstructions (e.g., beams on the roof, partitions in the house, etc.) present in the environment may affect the signal coverage of the AP device 200.
In the embodiment of the present application, the CPE device 300 serves as a radio frequency signal detection point, which can detect radio frequency signals in its surrounding environment at any time/periodically, or can perform radio frequency signal detection when receiving a detection command from the AC device 100. If the CPE device 300 is within the signal coverage range of a certain AP device 200, the radio frequency signal transmitted by the AP device 200 may be detected, so as to obtain corresponding detection data; if the CPE device 300 is outside the signal coverage of another AP device 200, the radio frequency signal transmitted by that AP device 200 cannot be detected. It should be appreciated that the same CPE device 300 may detect the radio frequency signals transmitted by one or more AP devices 200, thereby obtaining corresponding detection data, including information about the radio frequency signals transmitted by the one or more AP devices 200 detected by the CPE device 300.
In a possible embodiment, the detection data may include an identification of the AP device 200 (including a communication address, a name, a service set identifier (service set identifier, SSID) and the like of the AP device 200), a protocol type, and one or more radio frequency parameters including a channel, a bandwidth, a power, a frequency, a signal strength, a noise level, a data transmission rate and the like of the detected radio frequency signal, which is not particularly limited by the present application. The signal strength of the rf signal is generally represented by a Received Signal Strength Indicator (RSSI) parameter.
For example, please refer to fig. 3, fig. 3 is a schematic diagram of an indoor scene provided in an embodiment of the present application. Two AP devices 200, denoted by AP1 and AP2, respectively, are installed on the ceiling of the room, and are collectively configured and managed by the AC device 100. It should be appreciated that in addition to AP1 and AP2, the AC device 100 may also be capable of controlling other AP devices 200, such as AP devices 200 in other rooms. AP1 and AP2 may transmit corresponding radio frequency signals into the room according to their current configurations, respectively. The radio frequency signals transmitted by the AP1 and the AP2 have a certain coverage area, and the signal coverage areas of the two signals may overlap.
It is assumed that a plurality of terminal apparatuses 400 (including terminals 1 to 7) in the room all have only a wired communication function and do not have a wireless communication function, so they cannot be directly networked through the AP1 and the AP 2. In order for these terminal devices 400 to achieve network access, a plurality of CPE devices 300, CPE1, CPE2, CPE3 and CPE4, respectively, are also arranged in the room. Wherein, terminal 1 is connected to CPE1 by wire, terminal 2 and terminal 3 are both connected to CPE2, terminal 4 is connected to CPE3, and terminal 5, terminal 6 and terminal 7 are all connected to CPE4. The CPE device 300 may receive the radio frequency signal transmitted by the AP1 or the AP2, and then convert the radio frequency signal into a wired signal, and provide the wired signal to the connected terminal device 400, so as to meet the network access requirement of the terminal device 400. It should be noted that the same CPE device 300 may select only one AP device 200 to access, but may detect radio frequency signals transmitted by one or more AP devices 200.
As shown in FIG. 4, assuming that the signal coverage of AP1 and AP2 overlap, CPE1, CPE2 and CPE3 are all within the signal coverage of AP1, CPE2, CPE3 and CPE4 are all within the signal coverage of AP 2. Thus, CPE1 may detect the radio frequency signal transmitted by AP1, CPE2 and CPE3 may both detect the radio frequency signal transmitted by AP1 and AP2, and CPE4 may detect the radio frequency signal transmitted by AP 2. The CPE1 may obtain corresponding detection data according to the radio frequency signal transmitted by the AP1 detected by itself, where the detection data may include the following contents:
Protocol type: 802.11n
Bandwidth (bandwidth): 20MHz (20 MHz)
Guard interval (shortGI): false
Data transfer rate (datarate): 26.0Mb/s
Channel (channel): 1
Frequency (frequency): 2412MHz
Signal intensity (signalpattern): 68% (unit: percentage)
Signal strength-66 dBm (unit: dBm)
Noise level (noiselevel): 0% (unit: percentage)
Noise level: 127dBm (unit: dBm)
It can be seen that the above detection data mainly includes information on bandwidth, data transmission rate, channel, frequency, signal strength, noise level, etc. of the radio frequency signal transmitted by the AP1 detected by the CPE1, and may further include more or less information, which is not particularly limited in the present application. Similarly, the CPE2 may also obtain corresponding detection data according to the radio frequency signals transmitted by the APs 1 and 2 detected by itself, including information of the radio frequency signal transmitted by the AP1 detected by the CPE2, and also including information of the radio frequency signal transmitted by the AP2 detected by the CPE 2. It should be noted that, because CPE1 and CPE2 are both within the signal coverage of AP1, they both detect the radio frequency signal transmitted by AP1, but the detection data obtained by both may be different, e.g., CPE1 may be farther from AP1, the signal strength of the detected radio frequency signal transmitted by AP1 may be lower, while CPE2 may be closer to AP1, and the signal strength of the detected radio frequency signal transmitted by AP1 may be higher.
Similarly, CPE3 and CPE4 may also detect radio frequency signals in their surroundings and obtain corresponding detection data, which is not described here. Note that the number, positional relationship, and the like of the AC device 100, the AP device 200, the CPE device 300, and the terminal device 400 in fig. 3 are merely examples, and the present application is not limited thereto.
In a possible embodiment, CPE device 300 may use tag-length-value (TLV) format to represent the detection data obtained by itself.
In the above example, CPE2 detects the radio frequency signals transmitted by AP1 and AP2, respectively, and obtains corresponding detection data. CPE2 may encode the above detection data in TLV format to obtain two TLV triplets, namely TLV1 (AP 1_mac, …, RSSI_1) and TLV2 (AP 2_mac, …, RSSI_2), corresponding to AP1 and AP2 in turn. Wherein, AP1_mac in the TLV1 bracket represents a media access control bit (media access control, MAC) address of AP1, rssi_1 represents signal strength of the radio frequency signal transmitted by AP1 and detected by CPE2, and other information may be included, which is not particularly limited; AP2_mac represents the MAC address of AP2, and rssi_2 represents the signal strength of the radio frequency signal transmitted by AP2 detected by CPE 2. Similarly, other CPE devices 300 may also encode their own acquired detection data in TLV format, as will be described herein without limitation.
In a possible embodiment, the CPE device 300 may detect, in addition to radio frequency signals transmitted by one or more AP devices 200 in the WLAN system, radio frequency signals transmitted by an illegal AP (AP device 200 not managed by the AC device 100 and not in the white list) or a non Wi-Fi device (such as a cordless phone, a bluetooth device, a microwave oven, a smart meter, etc.), which may cause a certain interference to the AP device 200/CPE device 300 in the WLAN system. That is, the CPE device 300 may also detect interference signals existing in its surrounding environment, collect information about the interference signals, and provide the AC device 100 with the information as a basis for tuning to avoid the influence of the interference sources as much as possible.
S202, the CPE device 300 transmits detection data to the AC device 100.
In a possible embodiment, each CPE device 300 may send its own acquired detection data to AC device 100 through a communication protocol such as a User Datagram Protocol (UDP), a CAPWAP protocol, or an 802.11 protocol.
In the above example, assume that CPE2 and AC device 100 communicate using CAPWAP protocol; CPE2 constructs a CAPWAP message based on the detection data obtained by itself and sends it to AC device 100. Accordingly, when AC device 100 receives a message sent by CPE2, it needs to perform message parsing to obtain specific information in the detected data.
In a possible embodiment, the CPE device 300 may periodically send itself obtained detection data to the AC device 100; alternatively, the CPE device 300 may temporarily store the detection data obtained by itself, and directly send the detection data stored by itself to the AC device 100 when the CPE device 300 receives the query instruction sent by the AC device 100; alternatively, the CPE device 300 starts to perform radio frequency signal detection when receiving a detection instruction of the AC device 100, and then the CPE device 300 transmits the obtained detection data to the AC device 100.
For example, as shown in fig. 3, the location of the AP devices 200 is relatively fixed (AP 1 and AP2 are fixedly mounted on the ceiling), while the location of each CPE device 300 is relatively flexible and can be moved as desired. The AC device 100 may send a detection command to some or all CPE devices 300 (e.g. send a detection command to a CPE device 300 whose location has been moved and CPE devices 300 nearby) when the location of a CPE device 300 changes, and then the CPE devices 300 perform radio frequency signal detection according to the detection command, and send the obtained detection data to the AC device 100.
For another example, when a new AP device 200 is on-line or an old AP device 200 is off-line, the AC device 100 may send a detection instruction to all or part of CPE devices 300 (such as CPE devices 300 near the AP device 200), and then the CPE devices 300 may detect radio frequency signals in the surrounding environment, respectively, and send the obtained detection data to the AC device 100.
S203, the AC device 100 adjusts the configuration of one or more AP devices 200 according to the detection data sent by the CPE device 300.
Wherein, the above-mentioned "one or more AP apparatuses 200" refers to one or more AP apparatuses 200 administered under the AC apparatus 100. That is, there may be only one configuration of the AP apparatuses 200 that needs to be adjusted, or there may be a plurality of configurations of the AP apparatuses 200 that need to be adjusted.
In a possible embodiment, the above configuration includes one or more of channel, bandwidth and transmit power. That is, AC device 100 may adjust the transmit power, channel, and/or bandwidth of one or more AP devices 200.
Specifically, as can be seen from the foregoing, each CPE device 300 can detect radio frequency signals in its vicinity and transmit the obtained detection data to the AC device 100. It is possible for AC device 100 to receive detection data uploaded by one or more CPE devices 300. Based on the detected data sent by the one or more CPE devices 300, the AC device 100 can learn about signal coverage in the current environment, and can reasonably plan the channel, the transmission power, the bandwidth, the frequency band, etc. of the one or more AP devices 200 through algorithms such as Dynamic Channel Allocation (DCA), transmission power control (transmit power control, TPC), dynamic bandwidth selection (dynamic bandwidth selection, DBS), dynamic frequency band adjustment (dynamic frequency assignment, DFA), etc. to improve the signal quality (e.g., higher signal strength, lower signal-to-noise ratio) obtained by the one or more CPE devices 300 accessing the AP devices 200.
As shown in fig. 3, CPE1, CPE2, CPE3 and CPE4 are CPE devices 300 in the same indoor environment, and each of them can detect radio frequency signals in its surrounding environment and obtain corresponding detection data, and transmit the obtained detection data to AC device 100.
Based on the detection data uploaded by each of CPE1, CPE2, CPE3 and CPE4, AC device 100 may obtain an optimal power division result through the TPC algorithm, so as to improve indoor wireless network signal coverage as much as possible, and reduce signal interference between different AP devices 200, thereby improving signal quality obtained when these CPE devices 300 access AP devices 200. It is assumed that the AC device 100 determines a power division result to boost the transmission power of the AP1 to a certain value to increase the signal coverage of the AP 1. AC device 100 may then send a configuration message to AP1 to instruct AP1 to adjust its transmit power to that value. After receiving the configuration message issued by AC device 100, AP1 adjusts its own transmit power based on the configuration message.
Similarly, based on the detection data uploaded by each of CPE1, CPE2, CPE3 and CPE4, AC device 100 may obtain an optimal channel division result through the DCA algorithm, so as to ensure that each AP device 200 may be allocated to an optimal channel, avoid signal interference between neighboring AP devices 200 (in order to avoid signal interference, neighboring AP devices 200 may only operate on non-overlapping channels), and ensure reliable transmission of data. Then, AC device 100 may issue the determined channel division result to AP1 and AP2, respectively, thereby completing the tuning process. It should be understood that the above signal division result and power division result may be issued together to the AP1 and the AP2.
It should be noted that, the AC device 100 may perform global radio frequency tuning, that is, the tuning scope is for all AP devices 200 managed by the AC device 100, and the AC device 100 coordinates channels and/or powers of each AP device 200 uniformly, so as to achieve the best overall, so that all CPE devices 300 can obtain better signal quality. The AC device 100 may further perform local radio frequency tuning, that is, the tuning scope is a part of the AP devices 200 managed by the AC device 100, and by adjusting the channels and/or power of the part of the AP devices 200, the local signal environment is optimized, so that the signal quality obtained by the part of the CPE devices 300 after tuning is better.
For example, as shown in fig. 3, it is assumed that AC device 100 determines that there is an interference signal transmitted by an illegal AP in the vicinity of CPE1 based on the detection data uploaded by CPE 1. Then, the AC device 100 may trigger local radio frequency tuning, and by adjusting the channel and/or power of the AP1, avoid the interference of the illegal AP as much as possible, and ensure a certain signal coverage area and quality, so that the CPE1 obtains better signal quality.
As another example, as shown in fig. 3, assuming that AC device 100 finds that the signal strength of the radio frequency signals obtained by accessing them to AP device 200 is low according to the detection data uploaded by CPE1, CPE2, CPE3 and CPE 4. AC device 100 may then trigger global radio frequency tuning to make CPE1, CPE2, CPE3, and CPE4 better overall signal quality by appropriately adjusting the channels and/or power of AP1 and AP 2.
In a possible embodiment, in addition to using the detection data uploaded by the one or more CPE devices 300, the AC device 100 may perform tuning calculation in combination with other information (such as location information and load information of each of the one or more CPE devices 300, location information of the AP device 200, size and structure information of a house, etc.), and then issue a corresponding configuration message to the one or more AP devices 200 according to the result of the tuning calculation, so as to adjust the configuration of the one or more AP devices 200, so as to improve signal coverage and quality. The user may also make some personalized settings, e.g., the user may set a power adjustment range of the AP device 200, within which the AC device 100 then needs to determine the appropriate transmit power for the AP device 200.
In a possible embodiment, after step S203 (i.e. after the AC device 100 adjusts the configuration of one or more AP devices 200), the AC device 100 may send an inquiry instruction to the CPE device 300, so that the CPE device 300 may re-detect the radio frequency signal in the surrounding environment, and upload the detected corresponding detection data to the AC device 100, so that the AC device 100 verifies the tuning result at this time to determine whether the tuning target is reached, for example, whether the signal quality (such as the signal strength, the signal-to-noise ratio, etc.) obtained by the CPE device 300 accessing the AP device 200 after this tuning is better than before the tuning. If the AC device 100 finds that the tuning does not reach the tuning target, the AC device 100 may perform tuning calculation again based on the detection data uploaded by the CPE device 300, and adjust the configuration of the one or more AP devices 200 again until the tuning target is reached.
In summary, in the tuning method provided in the embodiment of the present application, the CPE device 300 has a radio frequency signal detection function, and can detect the radio frequency signal in the surrounding environment. When the CPE device 300 detects a radio frequency signal transmitted by at least one AP device 200 under control of the AC device 100, the obtained detection data may be sent to the AC device 100, so as to serve as a basis for radio frequency tuning of the AP device 200 under control of the AC device 100. Because for the AP device 200, the CPE device 300 and other terminals with wireless functions are consistent in nature and exist as a client (station, STA), the detected data obtained by the CPE device 300 actually starts from the end side, and the AC device 100 uses the signal coverage actually perceived by the end side as the tuning basis, so that the configuration of the AP device 200 can be adjusted more accurately, and reasonable planning on the channel, the transmission power, and the like of the AP device 200 can be realized. After AC device 100 completes the adjustment of the configuration of one or more AP devices 200, the signal coverage quality in the environment may be improved, enabling one or more CPE devices 300 to obtain better signal quality.
It can be understood that, in the embodiment of the present application, the network device, such as the CPE device 300 in the WLAN system, is directly used as a detection point of the radio frequency signal, so that the actual signal coverage situation in the environment can be conveniently obtained. And the radio frequency tuning device does not need to be manually participated, can save labor investment, can quickly and conveniently perform radio frequency tuning at any time, and does not need to additionally use a special signal detection terminal. In addition, in the embodiment of the application, the detection of the radio frequency signal and the uploading of the detection data do not need the participation of the AP equipment 200, so that the pressure of the AP equipment 200 can be reduced, and the current service of the AP equipment 200 is not influenced.
Referring to fig. 5, fig. 5 is a flowchart of another tuning method provided in an embodiment of the present application, where the method is used in the AC device 100, and may include the following steps:
s501, receiving detection data sent by the CPE device 300, where the detection data includes information of radio frequency signals transmitted by at least one AP device 200 of the plurality of AP devices 200 managed by the AC device 100 detected by the CPE device 300.
It should be noted that, the CPE device 300 may be one or more CPE devices 300, that is, the AC device 100 may receive the detection data sent by the one or more CPE devices 300, which is used as a basis for tuning.
In one possible implementation, the information of the radio frequency signal transmitted by the at least one AP device 200 detected by the CPE device 300 includes: the identity of the at least one AP device 200 and one or more of the channel, bandwidth, power, frequency, signal strength, data transmission rate, and noise level of the radio frequency signal transmitted by the at least one AP device 200 detected by the CPE device 300. For details of this embodiment, please refer to the related description in the step S201, which is not repeated here.
In a possible embodiment, the above detection data of the CPE device 300 further includes: information of radio frequency signals transmitted by other devices than the above-described plurality of AP devices 200, which are detected by the CPE device 300.
That is, the CPE device 300 may detect, in addition to the radio frequency signals transmitted by one or more AP devices 200 under the control of the AC device 100, radio frequency signals transmitted by other devices, such as radio frequency signals transmitted by illegal APs or other interference sources, i.e., interference signals. Therefore, the detection data sent by the CPE device 300 to the AC device 100 may also carry the relevant information of the interference signal, which is used as one of the judgment bases for the AC device 100 to adjust the configuration of the AP device 200. AC device 100 may avoid the impact of the above-described sources of interference on AP device 200/CPE device 300 as much as possible by rationally planning the configuration of one or more AP devices 200.
In one possible embodiment, the configuration includes one or more of transmit power, channel, and bandwidth.
S502, adjusting the configuration of one or more AP apparatuses 200 in the plurality of AP apparatuses 200 from the first configuration to the second configuration according to the detection data.
The first configuration refers to a configuration of the one or more AP devices 200 before the present tuning, and the second configuration refers to a configuration of the one or more AP devices 200 that needs to be completed in the present tuning.
Specifically, the signal quality may be more preferably: the signal strength obtained by the CPE device 300 when the one or more AP devices 200 are configured in the second configuration by accessing the AP device 200 is greater than the signal strength obtained by the CPE device 300 when the one or more AP devices 200 are configured in the first configuration by accessing the AP device 200. The signal quality may be better: the signal-to-noise ratio of the CPE device 300 accessing the AP device 200 when the one or more AP devices 200 are configured in the second configuration is less than the signal-to-noise ratio of the CPE device 300 accessing the AP device 200 when the one or more AP devices 200 are configured in the first configuration. Of course, the two conditions may be combined, and after tuning, the CPE device 300 accesses the AP device 200 to obtain a higher signal strength and a lower signal-to-noise ratio.
It should be appreciated that one CPE device 300 may access one of the AP devices 200 under the control of the AC device 100. The AP devices 200 that the CPE device 300 accesses when the configuration of the one or more AP devices 200 is in the first configuration may be different from the AP devices 200 that the CPE device 300 accesses when the configuration of the one or more AP devices 200 is in the second configuration, i.e., the AP devices 200 that the CPE device 300 accesses before and after tuning may be different. Of course, the AP devices 200 to which the CPE device 300 accesses before and after tuning may be the same.
In one possible implementation, step S502 may include: AC device 100 determines a second configuration of one or more AP devices 200 based on the detection data; AC device 100 sends a configuration message to the one or more AP devices 200, where the configuration message is used to instruct the one or more AP devices 200 to adjust their configuration from the first configuration to the second configuration.
That is, the AC device 100 may determine one or more AP devices 200 to which a configuration needs to be adjusted according to the detection data transmitted from the CPE device 300, and determine a second configuration to which the one or more AP devices 200 need to be adjusted. Then, the AC device 100 may adjust the configuration of the one or more AP devices 200 from the previous first configuration to the second configuration by transmitting a configuration message to the one or more AP devices 200, thereby completing the tuning process.
In one possible embodiment, the signal quality obtained by the CPE device 300 accessing the AP device 200 when the configuration of the one or more AP devices 200 is the second configuration is better than the signal quality obtained by the CPE device 300 accessing the AP device 200 when the configuration of the one or more AP devices 200 is the first configuration. That is, the tuning target may be that the signal quality obtained by the single CPE device 300 accessing the AP device 200 after tuning is better.
In another possible embodiment, for a plurality of CPE devices 300 including the CPE device 300, the signal quality obtained by accessing the AP device 200 when the configuration of the one or more AP devices 200 is the second configuration is better than the signal quality obtained by accessing the AP device 200 when the configuration of the one or more AP devices 200 is the first configuration. That is, the tuning target may be that the signal quality obtained by the plurality of CPE devices 300 after tuning is better for the AP device 200 as a whole, in which case there may be a case where the signal quality obtained by the single CPE device 300 after tuning is worse, but the signal quality obtained by the plurality of CPE devices 300 as a whole is improved from the viewpoint of the plurality of CPE devices 300, and the second configuration is an optimal result of tuning among the plurality of CPE devices 300.
In one possible implementation, before AC device 100 receives the detection data sent by CPE device 300, AC device 100 may instruct CPE device 300 to send the detection data to AC device 100.
That is, AC device 100 may actively request acquisition of detection data from CPE device 300. For example, AC device 100 may send an indication to CPE device 300 to upload detection data at any time or periodically. The CPE device 300 may transmit the detection data stored in itself to the AC device 100 when it receives an instruction from the AC device 100, or may start signal detection when the CPE device 300 receives the instruction, and transmit the obtained detection data to the AC device 100.

Referring to fig. 6, fig. 6 is a flowchart of another tuning method provided in an embodiment of the present application, where the method is used for the CPE device 300, and may include the following steps:

In one possible embodiment, the information of the radio frequency signal transmitted by the at least one AP device 200 detected by the CPE device 300 includes: the identity of the at least one AP device 200 and one or more of the channel, bandwidth, power, frequency, signal strength, data transmission rate, and noise level of the radio frequency signal transmitted by the at least one AP device 200 detected by the CPE device 300. For details of this embodiment, please refer to the related description in the step S201, which is not repeated here.
In a possible embodiment, the above detection data further includes: information of radio frequency signals transmitted by other devices than the above-described plurality of AP devices 200, which are detected by the CPE device 300. For details of this embodiment, please refer to the relevant portion in the aforementioned step S201, which is not repeated here.
In one possible embodiment, the configuration includes one or more of transmit power, channel, and bandwidth.
In one possible embodiment, CPE device 300 may perform radio frequency signal detection to obtain detection data and then store the detection data; when the CPE device 300 receives the query command from the AC device 100, it sends the detection data stored in itself to the AC device 100 according to the query command.
That is, CPE device 300 may actively perform signal detection without having to begin detection upon receipt of an indication from AC device 100. For example, the CPE device 300 may periodically detect the radio frequency signal in its surrounding environment, obtain corresponding detection data, and store the detection data temporarily in the memory of the CPE device 300. When the CPE device 300 receives the query instruction of the AC device 100, the detection data in the own memory may be directly sent to the AC device 100, without the CPE device 300 consuming time to detect, so that the time for the AC device 100 to acquire the detection data of the CPE device 300 can be shortened, and the time for the whole tuning process can be shortened.
In one possible embodiment, the CPE device 300 may receive the detection command sent by the AC device 100, and then perform radio frequency signal detection according to the detection command to obtain the detection data.
That is, the AC device 100 may actively send a detection instruction to the CPE device 300 to instruct the CPE device 300 to perform radio frequency signal detection, i.e. the CPE device 300 does not actively perform signal detection, and only starts signal detection when the AC device 100 needs, so that energy consumption of the CPE device 300 may be saved. After the CPE device 300 receives the detection instruction of the AC device 100, it may start to perform radio frequency signal detection to obtain corresponding detection data, and send the detection data to the AC device 100 as a basis for tuning.
S602, transmitting the detection data to the AC device 100, so that the AC device 100 adjusts the configuration of one or more AP devices 200 of the plurality of AP devices 200 from the first configuration to the second configuration according to the detection data.
In one possible embodiment, the signal quality obtained by the CPE device 300 accessing the AP device 200 when the one or more AP devices 200 are configured in the second configuration is better than the signal quality obtained by the CPE device 300 accessing the AP device 200 when the one or more AP devices 200 are configured in the first configuration.
In yet another possible embodiment, for a plurality of CPE devices 300 including the CPE device 300, they access the AP device 200 to obtain a better signal quality when the one or more AP devices 200 are configured in the second configuration than when they access the AP device 200 when the one or more AP devices 200 are configured in the first configuration.
