Description

[0001] The present application relates to the field of communication technologies, and in particular to wireless access methods, devices, systems, and readable storage media. Background Art

[0002] Wireless routers have limited signal coverage. In large venues like shopping malls, office buildings, and schools, wireless routers alone cannot provide comprehensive coverage. An AP (Wireless Access Point, also known as a WAP) receives signals from wireless routers and forwards them to more distant areas, thereby extending the coverage of a wireless network.

[0003] To improve signal stability, signals between APs may overlap. When a WiFi terminal enters a wireless coverage area, it selects a candidate signal for connection based on its own algorithm. However, this candidate signal may not be the optimal signal, resulting in a poor wireless experience for users.

[0048] Because wireless access points often respond to probe requests based solely on their own performance without considering the specific performance of other wireless access points, this can easily lead to wireless devices not accessing the network through the optimal wireless access point, resulting in a poor wireless experience. Based on this, this application proposes that after receiving a probe request, the wireless access point aggregates the probe signal strength information and sends it to an access controller. The access controller then compares the strength of each wireless access point to determine a response priority, allowing the wireless access point to provide differentiated probe responses. Specifically, after a wireless device broadcasts a probe request, wireless nodes that receive the probe request will feed back the probe signal strength corresponding to the probe request to the access control device. In other words, the access control device can collect the probe signal strengths from different wireless access points. Since a stronger signal indicates a better wireless experience, the access control device can determine the optimal access order for wireless access points based on the probe signal strengths. Then, based on the optimal access order, the wireless access point's response priority for the probe request is determined, and different response priorities are fed back to different wireless access points. In this way, the wireless access point can feed back probe responses to the wireless device based on the response priority. Based on these probe responses, wireless devices can access the best wireless access point, thereby improving the user's wireless experience.

[0061] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. Obviously, the embodiments described are only a part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making any creative efforts are within the scope of protection of the present application.

[0062] Please refer to Figure 1 , Figure 1 This is a flowchart of a wireless access method in an embodiment of the present application, which is applied to an access control device. The method includes the following steps:

[0063] S101: Receive detection signal strength information sent by multiple wireless access points.

[0064] When a wireless device needs to access a wireless local area network (WLAN), a probe request is broadcast. A wireless device is a terminal that needs to access a WLAN. The wireless device can be a smartphone, laptop, tablet, wearable device, or other WIFI-enabled device.

[0065] In this embodiment, the multiple wireless access points represent at least two wireless access points.

[0066] For example, a wireless device broadcasts a probe request. A probe request is a signal frame sent by a wireless device in a wireless network to detect available wireless networks in the surrounding area. The Probe Request frame includes fields for identifying the device and the purpose of the request, such as the device's MAC address, which allows the wireless access point to identify the wireless device sending the probe request; the SSID field, which, if a specific SSID is specified, indicates that the wireless device wishes to connect to the network with this specific name; and information about the wireless standards and encryption methods supported by the wireless device, so that the wireless access point can determine whether it can communicate and connect with the device based on this information.

[0067] For example, when a wireless device (such as a mobile phone or laptop) turns on wireless networking, it proactively sends Probe Request frames to search for nearby wireless access points (APs). This allows the device to obtain information about available wireless networks, such as the network name (SSID), signal strength, and supported protocols, allowing the user to select and connect to the appropriate wireless network.

[0068] After a wireless device broadcasts a probe request, wireless access points within its signal range receive it. Due to location differences and other factors, the strength of the probe signal received by these access points within the signal range of the wireless device's probe request may vary. To facilitate wireless devices connecting to the optimal wireless access point, these access points send the probe signal strength to the access control device.

[0069] That is, after the wireless device broadcasts the detection request, the access control device can collect the detection signal strength information corresponding to each wireless access point that can receive the detection request.

[0070] The probe signal strength information includes the strength of the probe signal corresponding to the probe request received by the wireless access point and the address of the sender of the probe request. Specifically, the signal strength information may include the strength of the probe signal corresponding to the probe request and the MAC address of the wireless device (i.e., the address from which the probe request was sent). Based on the probe signal strength information, the signal strength corresponding to the same probe request can be compared across different wireless access points.

[0071] S102: Determine an optimal access sequence for multiple wireless access points using the detected signal strength information.

[0072] Based on all the probe signal strength information corresponding to the same probe request, it is possible to determine which wireless access points are within the wireless device's signal range, and also to determine the signal strengths at which these wireless access points receive the probe request. Stronger signal strengths indicate more stable wireless network access. Therefore, in this embodiment, the optimal order for accessing wireless access points can be determined based on the probe signal strength information.

[0073] In a specific embodiment of the present application, using the detection signal strength information to determine the optimal access order of multiple wireless access points includes:

[0074] Using the detected signal strength information, multiple wireless access points are sorted according to signal strength;

[0075] The sorting result is determined as the optimal access order.

[0076] For ease of description, the above steps are combined and explained below.

[0077] In this embodiment, the detection signal strength information may include a unique identifier of the detection request, a signal strength of the detection request, and a unique identifier of the wireless access point.

[0078] In this way, after receiving the probe signal strength information, the access control device can clearly determine which wireless access points have received the probe signal for the same probe request broadcast by the same wireless device, as well as the specific strength of the probe signal. It can then sort the wireless access points that received the same probe request based on the strength, thereby obtaining the optimal access order.

[0079] For example, in a wireless LAN (WLAN), there are 10 wireless access points (APs). When a wireless device broadcasts a probe request, APs 1, 2, and 3 all receive it. After normalizing the signal strengths of the probe requests, APs 1, 2, and 3 receive a signal strength of 0.6, 0.8, and 0.4, respectively. All three APs send this signal strength information to the access control device. Based on this signal strength information, the access control device ranks the APs, resulting in the optimal access order: AP 2, AP 1, and AP 3.

[0080] S103: Determine the response priorities of multiple wireless access points using the optimal access sequence.

[0081] After the optimal access sequence is determined based on the detection signal strength information, the response priorities of the multiple wireless access points to the detection request may be determined based on the optimal access sequence.

[0082] In a specific embodiment of the present application, using the optimal access order to determine the response priorities of multiple wireless access points includes determining the response priorities based on a ranking and segmentation rule of the optimal access order. Specifically, a higher response priority indicates a greater detection signal strength, which can be determined based on different segmentation rules.

[0083] Specifically, the optimal access sequence is divided according to a segmentation rule corresponding to the number of the multiple wireless access points to obtain a plurality of segments; wherein the number of the segments is less than or equal to the preset number of levels of the response priority;

[0084] The response priority is determined according to the corresponding relationship between the segment sorting and the priority.

[0085] Response priorities can be set to fixed, preset levels, such as high, medium, and low. Alternatively, they can be set to high and low, or to four or more levels. If the number of APs exceeds the preset number of levels, the number of APs can be compared to the preset number of levels, and the ratio is the number of APs in each segment. If the number of APs is lower than the number of response priorities, priority is assigned to each AP in each segment.

[0086] For example, for the same probe request, the signal strengths of AP1, AP2, and AP3 are AP3, AP1, and AP2, respectively. The optimal access order is determined to be AP3, AP1, and AP2. If the response priority is divided into three levels (high, medium, and low), one AP per segment, AP3 is assigned a high response priority, AP1 a medium response priority, and AP2 a low response priority. In other words, AP3's response priority is ultimately determined to be higher than AP1's, and AP1's response priority is higher than AP2's. This results in a response priority ranking that conforms to the optimal access order.

[0087] For example, for the same probe request, the signal strengths of AP1 to AP6 are AP1, AP4, AP2, AP5, AP6, and AP3, respectively. The optimal access order is determined to be AP1, AP4, AP2, AP5, AP6, and AP3. If the response priority is high, medium, and low, then two APs can be assigned to each segment: AP1 and AP4, AP2 and AP5, and AP6 and AP3, respectively. The earlier the segment, the higher the priority. Ultimately, AP1 and AP4 receive high response priority, AP2 and AP5 receive medium response priority, and AP6 and AP3 receive low response priority.

[0088] Of course, in practical applications, the segments can also be divided unevenly, that is, the number of PAs corresponding to different segments can be different. In this way, the final response priority can be such that there is only one high priority, several medium priorities, and several low priorities.

[0089] Of course, in actual applications, the response priority can also be comprehensively determined in combination with the load situation of the wireless access point, the device status, etc.

[0090] S104: Feedback different response priorities to different wireless access points among the multiple wireless access points, so that different wireless access points feed back probe responses according to the response priorities.

[0091] After determining the response priorities corresponding to the wireless access points, the access control device can feed back different response priorities to the wireless access points.

[0092] After receiving the response priority belonging to itself, the wireless access point can feed back a detection response to the wireless device according to the response priority.

[0093] The probe response can be performed by sending a Probe Response frame. In this way, the wireless device can select the wireless access point with the strongest signal and the best performance to connect to based on these probe responses.

[0094] An access control device applies the method provided in an embodiment of the present application, including: receiving probe signal strength information sent by multiple wireless access points; determining an optimal access order for the wireless access points using the probe signal strength information; determining a response priority for the wireless access points using the optimal access order; and feeding back different response priorities to different wireless access points among the multiple wireless access points, so that the different wireless access points feed back probe responses according to the response priority.

[0095] Because wireless access points often respond to probe requests based solely on their own performance without considering the specific performance of other wireless access points, this can easily lead to wireless devices not accessing the network through the optimal wireless access point, resulting in a poor wireless experience. Based on this, the present application proposes that after receiving a probe request, the wireless access point aggregates the probe signal strength information and sends it to an access controller. The access controller then compares the strength of each wireless access point to determine a response priority, allowing the wireless access point to provide differentiated probe responses. Specifically, in the present application, after a wireless device broadcasts a probe request, wireless nodes that receive the probe request will feed back the probe signal strength corresponding to the probe request to the access control device. In other words, the access control device can collect the probe signal strengths from different wireless access points. Since a stronger signal indicates a better wireless experience, the access control device can determine the optimal access order for wireless access points based on the probe signal strengths. Then, based on the optimal access order, the wireless access point's response priority for the probe request is determined, and different response priorities are fed back to different wireless access points. In this way, the wireless access point can feed back probe responses to the wireless device based on the response priority. Based on these probe responses, wireless devices can access the best wireless access point, thereby improving the user's wireless experience.

[0096] Please refer to Figure 2 , Figure 2 This is a flow chart of another wireless access method in an embodiment of the present application, which is applied to a wireless access point. The method includes the following steps:

[0097] S201: Receive a probe request broadcast by a wireless device.

[0098] In this embodiment, an access control device and multiple wireless access points can be deployed in a wireless local area network, and a communication connection can be established between the access control device and the wireless access points. There is no limitation on the distance between the multiple wireless access points or their spatial deployment locations.

[0099] When the wireless LAN is deployed and enters working mode, the wireless access point can receive detection requests broadcast by wireless devices within its signal range.

[0100] Specifically, when a wireless device needs to connect to a wireless LAN, it can broadcast a probe request, that is, broadcast a Probe Request frame. At this time, the wireless access point within the signal range of the wireless device can receive the Probe Request frame. When the wireless LAN deploys multiple wireless access points, one or more wireless access points may receive the same probe request. For each wireless access point that receives the probe request, the following steps can be performed: Figure 2 The steps of the wireless access method shown are used to process the detection request.

[0101] S202: Determine signal strength information of the detection request.

[0102] After receiving the probe request, the wireless access point may perform strength detection on the probe signal corresponding to the probe request, thereby determining signal strength information of the probe request based on the detection result.

[0103] The signal strength information may include a unique identifier of the probe request, a unique identifier of the wireless access point itself, a unique identifier of the wireless device, and the like.

[0104] Of course, in practical applications, in order to facilitate access control and comparison of signal strengths, the signal strength corresponding to the detection signal is also clarified and then normalized, such as normalizing the signal strength to between 0 and 1.

[0105] S203: Send signal strength information to the access control device.

[0106] After determining the signal strength information, the wireless access point may send the signal strength information to the access control device.

[0107] Of course, in actual applications, it's also possible to configure the access control device to only send signal strength information for probe requests with stronger signals. This can reduce the processing burden on the access control device when a weak probe signal is received. For example, a signal strength threshold can be set. When a probe signal strength is greater than or equal to the threshold, the corresponding signal strength information is sent to the wireless controller; when a probe signal strength is less than the threshold, the probe request is ignored. This signal strength threshold can be set and adjusted based on actual conditions and is not detailed here.

[0108] S204: Receive the response priority fed back by the access control device.

[0109] The response priority is determined by the access control device based on signal strength information sent by multiple wireless access points.

[0110] Specifically, the response priority is the response priority of the wireless access point determined by the access control device using the optimal access sequence after determining the optimal access sequence based on signal strength information sent by a plurality of wireless access points.

[0111] After receiving the signal strength information, the access control device can perform the following operations: Figure 1 The processing flow shown is as follows. That is, the access control device will feedback the response priority to the wireless access point. For the specific processing process of the access control device, please refer to the description of the above embodiment, which will not be repeated here.

[0112] S205: Feedback a probe response to the wireless device according to the response priority.

[0113] After receiving the response priority, the wireless access point may feed back a probe response to the wireless device according to the response policy corresponding to the response priority.

[0114] That is, based on different response priorities, different probe responses are fed back to the wireless device.

[0115] In a specific embodiment of the present application, feeding back a probe response to the wireless device according to the response priority includes:

[0116] Use response priorities to determine the length of delays;

[0117] After the delay period is reached, a probe response is fed back to the wireless device.

[0118] In this embodiment, the higher the response priority, the shorter the delay time. In this way, the response time of the probe response is regulated for probe requests with different response priorities so that the wireless device preferentially selects the wireless access point with a high response priority for network connection.

[0119] For example, for a high response priority, the delay period can be 0, meaning the wireless access point immediately sends a probe response to the wireless device after receiving the response priority from the access control device. For a low response priority, the delay period is not 0, meaning the wireless access point waits for the delay period before sending a probe response to the wireless device after receiving the response priority from the access control device. This allows the high-priority wireless access point to send a probe response to the wireless device more quickly, allowing the wireless device to select the high-priority wireless access point as the network access point based on its own selection algorithm.

[0120] In a specific embodiment of the present application, feeding back a probe response to the wireless device according to the response priority includes:

[0121] Use response priority to determine response signal strength;

[0122] According to the response signal strength, the probe response is fed back to the wireless device.

[0123] In this embodiment, the higher the response priority, the stronger the response signal strength. Thus, for probe requests with different response priorities, the signal strength of the probe response is regulated so that wireless devices preferentially select wireless access points with higher response priorities for network connection. The higher the response priority, the greater the corresponding signal strength.

[0124] For example, for a high response priority, the signal strength can be 1. This means that after receiving the response priority sent by the access control device, the wireless access point will use 100% signal strength when sending a probe response to the wireless device. For a low response priority, the signal strength is lower than 1. This means that after receiving the response priority sent by the access control device, the wireless access point will weaken the response signal strength when sending a probe response to the wireless device. This allows the wireless access point with a high response priority to send a probe response to the wireless device more quickly, allowing the wireless device to select the wireless access point with a high response priority as the access point for network connection based on its own selection algorithm.

[0125] In a specific embodiment of the present application, feeding back a probe response to the wireless device according to the response priority includes:

[0126] Fill the response priority into the response message;

[0127] Feedback a response message to the wireless device.

[0128] In this embodiment, the response priority can be filled into the response message. In this way, after the response message is sent to the wireless device, the wireless device can select the best wireless access point for access based on the response priority in the received response message.

[0129] Applying the method provided by an embodiment of the present application in a wireless access point includes: receiving probe signal strength information sent by multiple wireless access points; determining an optimal access order for the wireless access points using the probe signal strength information; determining a response priority for the wireless access points using the optimal access order; and feeding back different response priorities to different wireless access points among the multiple wireless access points, so that the different wireless access points feed back probe responses according to the response priority.

[0130] Because wireless access points often respond to probe requests based solely on their own performance without considering the specific performance of other wireless access points, this can easily lead to wireless devices not accessing the network through the optimal wireless access point, resulting in a poor wireless experience. Based on this, the present application proposes that after receiving a probe request, the wireless access point aggregates the probe signal strength information and sends it to an access controller. The access controller then compares the strengths of the probe signals from various wireless access points to determine a response priority, enabling the wireless access point to provide differentiated probe responses. Specifically, in the present application, after receiving a probe request, the wireless access point first determines the signal strength information associated with the probe request and then feeds this strength information back to the access control device. In other words, the access control device can collect the probe signal strengths from different wireless access points. Since a stronger signal indicates a better wireless experience, the access control device can determine the optimal access order for the wireless access points based on the probe signal strengths. Based on this optimal access order, the wireless access point's response priority for the probe request is then determined, and different response priorities are fed back to different wireless access points. After receiving the response priority information from the access control device, the wireless access point can feed back a probe response to the wireless device based on the response priority. Based on these probe responses, wireless devices can access the best wireless access point, thereby improving the user's wireless experience.

[0131] Corresponding to the above method embodiment, the embodiment of the present application further provides an access control device. The access control device described below is Figure 1 The wireless access methods shown can be referenced to each other.

[0141] The power management circuit provides a stable power supply to the AC and usually has a redundant power supply design to improve the reliability and stability of the equipment and ensure continuous operation in the event of a power failure.

[0142] The steps in the wireless access method described above, which are applicable to an access control device, may be implemented by the structure of the access control device.

[0143] Corresponding to the above method embodiment, the embodiment of the present application further provides a wireless access point. A wireless access point described below is connected to Figure 2 The wireless access methods shown can be referenced to each other.

[0148] Specifically, the wireless access point may include: a wireless communication chip, a controller, an antenna, a memory, a power management circuit, and a network interface.

[0149] Among them, the wireless communication chip is used to process the sending and receiving of WiFi signals.

[0150] The controller can be specifically a microcontroller (MCU), which is used to control the working logic of the wireless access point, such as connecting to the network, managing data transmission, processing various instructions and protocols, etc.

[0151] Antenna: used to receive and send wireless signals, can be divided into internal antenna and external antenna.

[0152] Memory: used to store wireless access point firmware, configuration files, and some runtime data.

[0153] Power management circuit: ensures that the wireless access point works normally under various power conditions, including power conversion, voltage regulation, energy-saving control, etc.

[0159] The wireless device 503 is configured to broadcast a probe request, receive and use a probe response to select a target wireless access point to access the wireless local area network.

[0160] The following describes in detail the process of performing wireless access in a wireless access system.

[0161] Please refer to Figure 6 When a wireless device (wireless terminal) needs to connect to the network, it can broadcast proberequest data, and the AP within the detection signal range of the wireless device can receive the probe request.

[0162] Please refer to Figure 7 , the AP summarizes and reports the collected terminal data (including detection signal strength information) to the AC (access control device, also known as a centralized controller).

[0163] Please refer to Figure 8 ,AC summarizes the terminal signal strength and other parameters collected by different APs, and ,comprehensively calculates the optimal AP sequence list for wireless ,devices to access.

[0164] Please refer to Figure 9 ,AC sends different response priority parameters to the corresponding AP according to the ,optimal AP sequence list.

[0165] Please refer to Figure 10 ,Different APs fill their own response priority parameter information into the probe response message and reply to the wireless device.

[0166] Finally: The wireless terminal attempts to associate with the AP with the best signal based on the received probe response message. If the association fails, it will continue to try to associate with the AP with the second best signal.

[0167] It can be seen that in the wireless access system provided in the embodiment of the present application, all APs reply proberespone messages to the wireless device, which increases the range of options for the wireless device. The proberespone messages replied by different APs carry different parameter priorities, allowing the terminal to give priority to the AP with better signal. On the basis of allowing the wireless device to connect to the optimal AP first, the present application also retains the terminal's alternative connection objects, while ensuring the experience and reliability of terminal access.

[0168] Corresponding to the above method embodiment, an embodiment of the present application further provides a readable storage medium. The readable storage medium described below and the wireless access method described above can refer to each other.
