[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application is based on the Chinese patent application with application number 202410045660.5 and application date of January 11, 2024, and claims the priority of the Chinese patent application. The entire content of the Chinese patent application is hereby introduced into this application as a reference. Technical Field

[0003] The present application relates to the field of wireless network access technology, and in particular to a method, device, and storage medium for switching wireless access points for device interaction. Background Art

[0004] A wireless access point (AP) is a network device used to create wireless local area networks (WLANs), allowing wireless devices (such as laptops, smartphones, and tablets) to connect to the AP via Wireless Fidelity (WIFI) and then connect to a wired network or the Internet.

[0005] In a scenario with multiple APs, there may be a situation where too many wireless devices are connected to one AP, while too few are connected to other APs. This causes a load imbalance between the APs, resulting in resource waste and affecting the user experience of wireless devices.

[0006] The problem of AP load imbalance can be solved by AP switching. In related technologies, network switching is generally achieved through the following methods: Method 1, determining whether to switch APs based on signal strength, but this method cannot solve the problem of network stagnation caused by too many devices under the AP when the signal strength is strong enough; Method 2, by constructing Wi-Fi fingerprint data for each AP and uploading it to the server, the server uses a model to determine whether network switching is necessary based on the current Wi-Fi data and Wi-Fi fingerprint data. However, this method requires data construction work to prepare the Wi-Fi fingerprint data before the device is connected, and it needs to rely on the server for processing.

[0007] In summary, how to effectively implement AP switching and achieve the purpose of AP load balancing is an urgent problem that needs to be solved.

[0067] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0068] The following describes a method for switching wireless access points for device interaction according to an embodiment of the present application with reference to FIG1 to FIG9 , including:

[0069] S100: The master device obtains first device network information of each device under the same AP;

[0070] S110: The master device determines whether the AP is overloaded according to the network information of the first device;

[0071] S120: When the master device determines that the AP is overloaded, the master device obtains a screening queue according to the network information of the first device, where the screening queue includes devices whose specified network parameters are greater than an average value;

[0072] S130: The master device obtains wireless signal information of each device in the screening queue;

[0073] S140: The master device determines a first device to be switched, a corresponding target access point, and a corresponding target master device according to the wireless signal information;

[0074] S150: The master device sends a first switching request message to the switching target master device, and sends the first device network information corresponding to the first device to be switched to the switching target master device;

[0075] The master device is determined by election from the devices connected to the AP.

[0076] A master device is elected from among the devices connected to the AP. When the AP is overloaded, the master device selects devices with specified network parameters greater than the average value to form a screening queue. The master device then monitors the wireless signal information of each device in the screening queue to determine the first device to be switched, as well as the corresponding target access point and target master device. The master device then sends a first switching request message and the first device network information of the first device to be switched to the target access point to switch the first device to be switched to. In this way, when the connected AP is overloaded, the master device interacts with the first device to be switched to the target access point, thus achieving AP switching without relying on the server, reducing the load on the connected APs and balancing the load on each AP.

[0077] Based on the primary device network information of each device connected to the same AP, the master device can determine the number of devices connected to the AP and the network status of each device. It can also determine whether the AP is overloaded (i.e., if too many devices are connected, causing network instability), and trigger AP switching. This can avoid network congestion despite the AP providing sufficient signal strength. The master device also processes the information interactively, eliminating the need for server reliance and reducing the burden on the AP.

[0078] The master device interacts with the switching target master device under the switching target access point, and sends the first device network information of the first device to be switched to the switching target master device, so that the first device to be switched is connected to the target access point.

[0079] Devices under the AP may include mobile phones, tablet computers, virtual reality (VR) devices, etc.

[0080] It's important to note that the target access point is actually an AP, a different AP than the one connected to the master device. The target master device is the master device associated with the target access point. The terms AP and target access point, and master device and target master device, are relative terms. From the perspective of another AP, the AP can also be the target access point, and similarly, the master device can also be the target master device.

[0081] Referring to FIG2 , in some embodiments of a wireless access point switching method for device interaction according to an embodiment of the present application, the method further includes:

[0082] S160: The master device obtains second device network information of the second device to be switched in response to the second switching request information;

[0083] S170: The master device determines whether to allow the second device to be switched to be switched based on the network information of the second device;

[0084] S180: When the master device determines that the cut-in is allowed, it sends an approval message; when it determines that the cut-in is not allowed, it sends a rejection message.

[0085] When the master device receives a second handover request message, indicating that the AP connected to the master device is the target access point for other APs to switch to, and that the master device is the target master device for other APs to switch to, the master device determines, based on the second device's network information, whether the connected AP allows the second device to switch to. If the AP's status is appropriate, the master device allows the second device to switch to the AP, achieving the AP switching goal. Thus, when switching APs for a device, the master devices under both APs interact to determine whether the AP switch is appropriate before executing the switch. This helps maintain AP stability and avoids issues where AP switching fails to improve the device's network status.

[0086] It should be noted that the first device to be switched and the second device to be switched are relative, and different names are used to distinguish them from the perspective of different APs. In fact, the first switching device and the second switching device can be the same device. For example, a mobile phone under wireless access point A needs to be switched. From the perspective of the master device of wireless access point A, the mobile phone is the first device to be switched, wireless access point B is the target access point, and the master device of wireless access point B is the target master device. From its perspective, the mobile phone is the second device to be switched.

[0087] 3 , in some embodiments of a wireless access point switching method for device interaction according to an embodiment of the present application, the first device network information includes a first delay value and a first traffic value, and S110 includes:

[0088] S111: Calculating an average flow value and an average delay value according to the first delay value and the first flow value of each device;

[0089] S112: When the average traffic value and the average delay value continue to increase within a first preset time, it is determined that the AP is overloaded.

[0090] The master device collects statistics on the average traffic and average latency of the AP. If these values ​​continue to increase for a predetermined period of time, it indicates that too many devices are connected to the AP, causing it to be overloaded and unable to provide stable and reliable network access services to all devices. By monitoring the average traffic and average latency values, the master device can promptly determine whether the AP is overloaded and trigger an AP handover.

[0091] The first preset time can be specifically set according to the actual application environment.

[0092] In some embodiments of the wireless access point switching method for device interaction according to the embodiment of the present application, the step S120 includes:

[0093] According to the first flow value and the first delay value of each of the devices, the devices whose flow is greater than the average flow value or whose delay is greater than the average delay value are selected to form the screening queue.

[0094] If the master device encounters an AP overload, it obtains first network device information from each device, including first traffic and first delay values, compares this information with the average traffic and average delay values, and selects devices with values ​​greater than the average traffic or average delay values ​​for inclusion in a screening queue. This creates a screening queue comprised of devices with poor network conditions, facilitating subsequent selection of the first device to be switched, prioritizing AP switching for devices with poor network conditions. This improves the performance of devices with poor network conditions while preventing impacts on devices with good network conditions.

[0095] At the same time, a screening queue is formed, and the main device only needs to monitor the devices in the screening queue, which helps to reduce the monitoring burden of the main device.

[0096] 4 , in some embodiments of a method for switching a wireless access point for device interaction according to an embodiment of the present application, the wireless signal information includes surrounding wireless interference strength and current signal strength, and S140 includes:

[0097] S141: The device whose surrounding wireless interference strength is greater than the current signal strength is selected as the first device to be switched and removed from the screening queue;

[0098] S142: According to the wireless interference intensity of the first device to be switched, the AP with the greatest interference intensity is selected as a target access point for switching.

[0099] The master device monitors the wireless interference strength and current signal strength of devices in the screening queue. If a device's wireless interference strength is greater than its current signal strength, indicating that another AP is providing a stronger signal than the currently connected AP, the master device is selected as the first device to be switched, and the AP with the highest wireless interference strength is selected as the target access point. This selection of the first device to be switched based on wireless interference strength and current signal strength helps ensure that the first device to be switched receives sufficient wireless signal strength after the AP switch, thus maintaining a good network experience for the device.

[0100] It is understandable that wireless interference strength is relative to current signal strength. The wireless signal strength provided by an AP is the current signal strength from the perspective of its subordinate devices, and is the wireless interference strength from the perspective of other APs.

[0101] 5 , in some embodiments of a wireless access point switching method for device interaction according to an embodiment of the present application, the first delay value includes a first server delay value and a first access point delay value, and the second device network information includes a second server delay value, a second access point delay value, and a second traffic value; and S170 includes:

[0102] S171: Subtract the corresponding first access point delay value from the first server delay value of each device as a first horizontal coordinate, and use the first traffic value as the first horizontal coordinate to form a first coordinate point;

[0103] S172: Acquire the first coordinate points formed by each of the devices within a second preset time, and connect the first coordinate points on the edge to form a first coordinate area based on all the first coordinate points;

[0104] S173: Subtract the second access point delay value from the second server delay value as a second horizontal coordinate, and use the second traffic value as a second vertical coordinate to form a second coordinate point;

[0105] S174: Acquire the second coordinate points formed within the second preset time, and connect the second coordinate points on the edge to form a second coordinate area based on all the second coordinate points;

[0106] S175: When the second coordinate area is within the first coordinate area, or the average value of the second horizontal coordinate is less than or equal to the average value of the first horizontal coordinate, or the product mean value of the second vertical coordinate is less than or equal to the average value of the first vertical coordinate, it is determined that the second device to be switched is allowed to be switched in; otherwise, it is determined that the second device to be switched is not allowed to be switched in.

[0107] Referring to Figure 10 , within a second preset time period, the master device obtains the second server delay value, second access point delay value, and second traffic value of the second device to be switched, forming multiple second coordinate points. These edge second coordinate points are then connected to form a second coordinate area. The second coordinate area reflects the network status and needs of the second device to be switched. Similarly, a first coordinate area is obtained, formed by combining the various devices under the AP. The first coordinate area reflects the network status and resources currently provided by the AP to each device. If the second coordinate area is within the first coordinate area, as shown in Figure 11 , this indicates that the network status and resources currently provided by the AP meet the network status and needs of the second device to be switched, and the second device to be switched is allowed to connect to the AP. Alternatively, if the second coordinate area is not within the first coordinate area, but the average value of the second abscissa or second ordinate of the second device to be switched is less than or equal to the average value of the first abscissa or the mean value of the first ordinate, as shown in Figure 12 , it is determined that the second device to be switched can meet the network needs of the AP and will not impose excessive load on the AP, and the second device to be switched is allowed to connect to the AP.

[0108] Referring to Figure 13, when the second coordinate area is outside the first coordinate area and the average value of the second horizontal coordinate and the average value of the second vertical coordinate are greater than the average value of the first horizontal coordinate and the product mean of the first vertical coordinate, the master device does not allow the second device to be switched to access the AP, so as to avoid excessive load on the AP and help maintain stable operation of the AP.

[0109] 6 , in some embodiments of a wireless access point switching method for device interaction according to an embodiment of the present application, before step S100 , the method further includes:

[0110] S010: Obtain device operation information of each device under the same AP;

[0111] S020: Determine the number of election devices based on the number of the devices;

[0112] S030: Sort the devices according to the device operation information, and select the devices corresponding to the number of election devices to form an election queue;

[0113] S040: Obtain device status information of each device in the election queue, and calculate the election weight corresponding to each device;

[0114] S050: Select the device corresponding to the largest election weight as the master device;

[0115] The device operation information represents the performance resource status of the corresponding device, and the device status information represents the network status of the corresponding device.

[0116] Before AP switching, a master device must be elected. The number of devices participating in the election is determined based on the number of devices connected to the AP. Based on their operational information, a corresponding number of devices are selected to form an election queue. The election weight of each device in the election queue is calculated based on its device status information, and the device with the highest weight is selected as the master device. This ensures that the master device has sufficient performance resources and good network status to meet the requirements of interactive AP switching.

[0117] It should be noted that the master device requires sufficient performance resources to interact with and implement AP switching. Device operation information reflects the device's performance resources, which allows the selection of devices with sufficient performance resources to form the election queue. The master device also requires a good network status for communication interaction. Device status information reflects the device's network status, allowing the device with the best network status to be selected as the master device.

[0118] In some embodiments of the present application, the number of election devices may be determined by the following formula:

[0119] Where N is the number of devices under the AP, Min represents the minimum function, and Max represents the maximum function.

[0120] 7 , in some embodiments of a method for switching wireless access points for device interaction according to an embodiment of the present application, the device operation information includes processor utilization, memory utilization, negotiation rate, signal strength, and traffic value; and S030 includes:

[0121] S031: Calculate a ranking value corresponding to the device according to the processor utilization, the memory utilization, the negotiation rate, the signal strength, and the traffic value;

[0122] S032: Sort the devices according to the sorting value, and select the devices corresponding to the number of election devices to form an election queue.

[0123] The processor utilization, memory utilization, negotiation rate, signal strength, and traffic values ​​reflect the performance resource situation of the device. Based on this, a ranking value is calculated and used to sort each device based on its performance resource situation. Devices are selected in ascending order of ranking values ​​until the number of elected devices is reached, forming an election queue.

[0124] In some embodiments of the present application, the ranking value may be calculated according to the following formula:

[0125] Where C is the processor utilization, M is the memory utilization, N is the negotiation rate, D is the signal strength, and F is the total traffic value obtained within the preset time value.

[0126] 8 , in some embodiments of a method for switching a wireless access point for device interaction according to an embodiment of the present application, the step S040 includes:

[0127] S041: The first device in the election queue obtains device status information of each device in the election queue, where the device status information includes a negotiation rate value, a signal strength value, and an interference strength value;

[0128] It should be noted that the negotiated rate value may represent a data transmission rate in a theoretical state, for example, a data transmission rate that can be negotiated and successfully established between two devices during communication.

[0129] It should be noted that the interference intensity value represents the interference intensity corresponding to each device in the election queue.

[0130] S042: The first device in the election queue constructs a negotiation rate matrix, a signal strength matrix, and an interference strength matrix corresponding to the device according to the device status information within a third preset time;

[0131] S043: For the first device in the election queue, the negotiation rate matrix, the signal strength matrix and the interference strength matrix of each device are respectively merged and the values ​​in the matrix are sorted, and the election weight corresponding to the device is obtained according to the sorting position value of the corresponding value of each device.

[0132] After forming an election queue, the first device in the election queue has the best performance resources. Information is aggregated and processed within that device. By constructing the negotiation rate matrix, signal strength matrix, and interference strength matrix for each device, the network status of each device can be accurately reflected. These three matrices are then merged and sorted. Specifically, the values ​​in the matrices of each device are uniformly sorted. Then, based on the sorted positions of the values ​​in the three merged matrices, a sorting position value is obtained. The sum of the reciprocals of the sorting position values ​​is used as the election weight for each device. In this way, by constructing the matrices, merging and sorting them, and calculating the sorting position values, election weights are obtained. This method comprehensively reflects the network status of the devices, facilitates the accurate selection of the device with the best network status as the master device, and improves the efficiency and reliability of AP switching for the master device.

[0133] For ease of understanding, an example is given schematically. For example, the third preset time is 10 cycles, the negotiation rate and signal strength are obtained once per cycle, and the interference signal strength is obtained once every two cycles. The three matrices of a device are as follows:

[0134] Negotiated rate matrix: [526,527,510,532,522,529,712,547,513,416]

[0135] Signal strength matrix: [-40,-47,-52,-39,-67,-48,-68,-71,-67,-45]

[0136] Interference intensity matrix: [-56,-72,-86,-57,-82]

[0137] The three matrices of each device are merged and sorted as shown below:

[0138] Negotiated rate summary matrix: [712,683,612,605,547,529,527,526,510,416,...]

[0139] Signal strength summary matrix: [-25,-28,-31,-39,-40,-47,-48,-52,-67,-68,-71,...]

[0140] Interference strength summary matrix: [-92,-86,-82,-72,-57,-56,-45,...]

[0141] After obtaining the sorting position values ​​of the values ​​in the device matrix, the resulting matrix, such as the sorting position value of a device, is as follows:

[0142] Sorted position value summary matrix: [1,3,7,5,6,9,10,16,18,20,29,...]

[0143] It's understood that the ranking position summary matrix is ​​a summary of the ranking position values ​​corresponding to each value in the three matrices for a device. The election weight of the corresponding device is calculated based on the reciprocal sum of the ranking position values: election weight = 1 + 1 / 3 + 1 / 7 + .... The higher the ranking position, the greater the calculated election weight, indicating a better network status for the device.

[0144] When constructing the negotiation rate matrix, signal strength matrix, and interference strength matrix of each device, the master device can combine the unique identification code of each device, such as the media access control address, to facilitate subsequent sorting of the matrix values ​​and associate the values ​​with the corresponding devices.

[0145] It should be noted that before forming an election queue, the process of determining the number of election devices and forming an election queue based on the device operation information can be carried out in the AP. After the election queue is formed, the election queue information is broadcast to all devices or each device in the election queue; it can also be that each device exchanges information with each other through broadcasting, and each obtains the number of election devices and forms an election queue based on information processing.

[0146] 9 , in some embodiments of a wireless access point switching method for device interaction according to an embodiment of the present application, after S120 , the method further includes:

[0147] S121: The master device generates synchronization information according to the network information of the first device, and synchronizes the synchronization information to the devices in the election queue.

[0148] Taking into account the possibility that the master device may cut out the current AP and then elect a new master device, in order to prevent the new master device from lacking historical information of each device, the master device regularly generates synchronization information based on the network information of the first device and sends it to each device in the election queue for synchronization. When a new master device is elected, the AP can still maintain stable operation and AP switching can be performed normally, which is conducive to improving stability and reliability.
