[0043] With the continuous development of wireless communication technology, wireless networks have become an important part of people's daily life and work. As the core component of wireless networks, the performance and connection stability of wireless access points (APs) are crucial to the user's network experience. Before successfully connecting to an AP, the performance of the AP is usually judged only based on the RSSI of the AP. However, in addition to RSSI, factors such as frequency band, bandwidth, and whether it is in a DFS channel are also important factors affecting performance and stability. In addition, users have different usage preferences in different scenarios. Therefore, when evaluating the performance of an AP, its performance, stability, and security are comprehensively evaluated based on factors such as the frequency band, bandwidth, whether it is in a DFS channel, and encryption type of the AP. Considering scenario factors, you can select the AP with the best performance, highest stability, and strongest security to connect to, thereby obtaining a better network experience.

[0044] Exemplary Methods

[0045] This embodiment provides a method for selecting a wireless access point. Figure 1 As shown, the method comprises the following steps:

[0046] Step S100, obtaining environmental information, and selecting a scene mode according to the environmental information;

[0047] Specifically, when the user is connected to a wireless network, the environment in which the user is located can reflect the user's needs. By scanning and analyzing the environmental information, the scene in which the device is located can be determined. If the environmental information shows that the user is surrounded by green plants, it is inferred that the user is in an outdoor park, and the scene mode can be a park green space. If there are doctors and nurses in the environmental information, it is inferred that the user is in a hospital, and the scene mode can be a hospital.

[0048] In one implementation, step S100 in this embodiment includes the following steps:

[0049] Step S101, scanning the environment to obtain environmental information, wherein the environmental information includes geographic coordinate information and real scene information;

[0050] Step S102: Select the scene mode according to the environmental information, wherein the scene mode includes a default mode, an airport mode, a hospital mode and an office mode.

[0051] Specifically, geographic coordinate information can be obtained through the positioning system of the device. The geographic coordinates can be used to obtain the location information marked on the map, such as stadiums, hospitals, swimming pools, etc., and then the real-scene information can be obtained by scanning the environment. Real-scene information includes: trees, buildings, crowds, clothing, facilities, etc. By combining the geographic coordinate information and the environmental information obtained by the real-scene information, the environmental information can reflect the current environment. For example, if the geographic coordinate information is a hospital, but the user's environment is scanned and surrounded by green trees and blue sky and white clouds, it can be determined that the user's environmental information is an outdoor green space, and the scene mode is selected as outdoor. If the geographic coordinate information is a hospital, and the scanned user's environment has the words "operating room", it can be determined that the environmental information is a hospital, and the scene mode is selected as hospital. When the user's scene mode cannot be identified, the default mode can be used.

[0052] Step S200, calculating a comprehensive score of each wireless access point according to the scenario mode, wherein the comprehensive score evaluates the performance of the wireless access point in the scenario mode based on the operating frequency band, WIFI standard type, bandwidth, whether it is in a DFS channel indication, encryption type, and received signal strength;

[0053] Specifically, in the same scenario mode, the comprehensive performance of the wireless access point is measured by the comprehensive score of the wireless access point, and the comprehensive performance of the wireless access point is positively correlated with the score. For example, in the hospital scenario, the comprehensive score of AP1 is 85 points, and the comprehensive score of AP2 is 90 points, which means that in the hospital scenario, the comprehensive performance of AP2 is better than that of AP1.

[0054] In one implementation, the following steps are included before step S200 in this embodiment:

[0055] Step M200: search for accessible wireless access points, and calculate the performance indicators of each accessible wireless access point, wherein the performance indicators include a frequency band score, a standard type score, a bandwidth score, a DFS channel score, an encryption type score, and a received signal strength score.

[0056] Specifically, a query request for a wireless access point is sent to a wireless access point, and the obtained reply message includes an identifier and performance parameters of each of the wireless access points. The wireless access point that receives the reply message is marked as an accessible wireless access point, and is distinguished by the identifier of the wireless access point. The performance index of each accessible wireless access point can be calculated by the performance parameter, and the performance of the wireless access point can be evaluated by scoring each performance of the wireless access point.

[0057] Specifically, when the terminal searches for a wireless access point, the search for the AP may be automatically performed when the terminal has not established a Wi-Fi connection, or the search for the AP may be performed when triggered by a user, or the search for the AP may be performed when the terminal has established a Wi-Fi connection and is passively disconnected by the currently connected AP, or the search for the AP with a stronger signal may be performed when the terminal has established a Wi-Fi connection.

[0058] In one implementation, step M200 in this embodiment includes the following steps:

[0059] Step M201: Search for accessible wireless access points, and obtain the working frequency band, WIFI standard type, bandwidth, whether it is in a DFS channel, encryption type, and received signal strength of the accessible wireless access points;

[0060] Specifically, the working frequency band of the wireless access point indicates the WIFI protocol supported by the wireless access point, including 2.4G, 5G and 6G frequency bands. The WIFI standard types are 802.11n, 802.11ac, and 802.11ax. Bandwidth is an important indicator for measuring the speed of wireless devices. We divide the bandwidth into five intervals with 20MHz, 40MHz, 80MHz, and 160MHz as the dividing points. Bandwidth less than 40MHz is recorded as 20Hz. Bandwidth greater than or equal to 40MHz and less than 80MHz is recorded as 40MHz. Bandwidth greater than or equal to 80MHz and less than 160MHz is recorded as 80MHz. Bandwidth greater than or equal to 160MHz is recorded as 160MHz. DFS Dynamic Frequency Selection is one of the functions of the 5GHz wireless band. Originally, DFS channels were reserved for specific radar signals only. At present, relevant channels are open for use in accordance with relevant regional regulations. However, when a radar is detected on a DFS channel, it is necessary to quickly exit the channel and switch to another DFS channel, resulting in an unstable WIFI connection. Non-DFS channels are more stable in use, and the DFS channel indication indicates whether the wireless access point is in a DFS channel. An open network is a network without a password set, and any user can connect to and access the network. The security of this type of network is very low, and connecting to an open network is prone to attacks or leakage of personal information. A non-open network is a network that requires a password to connect. The security of this type of network is relatively high because only users who know the password can connect to the network. The encryption type indicates whether the wireless access point is encrypted. The received signal strength (RSSI) indicates the signal strength at a certain location within the coverage of a wireless network and is the most important indicator for measuring AP performance.

[0061] Step M202: score the working frequency band, WIFI standard type, bandwidth, whether it is in a DFS channel indication, encryption type, and received signal strength of the accessible wireless access point respectively to obtain a performance indicator of each accessible wireless access point.

[0062] Specifically, by assigning points to the above indicators, f(f) represents the frequency band score, f(b) represents the bandwidth score, f(s) represents the standard type score, f(d) represents whether it is in the DFS channel score, f(secy) represents the encryption type score, and f(r) represents the received signal strength score.

[0063] Specifically, different score values ​​are calculated according to the frequency band in which the wireless access point works. Currently, the WIFI protocol supports 2.4G, 5G, and 6G bands. The 2.4G band has a low operating frequency and a slow speed, while the 5G band has a higher frequency and can provide more bandwidth, thereby achieving a faster speed. The 6G band can provide more bandwidth than the 5G band. In terms of transmission speed, the 6G band has the fastest rate, followed by the 5G band and the 2.4G band. Therefore, the 2.4G band has 0 points, the 5G band has 5 points, and the 6G band has 10 points. The scoring rules are defined as follows:

[0064]

[0065] Different scores are calculated based on the WIFI standard type supported by the wireless access point. The scoring rules are defined as follows:

[0066]

[0067] Different score values ​​are calculated based on the bandwidth of the wireless access point. The larger the bandwidth, the faster the transmission speed. Therefore, 20MHz is 0 points, 40MHz is 3 points, 80MHz is 6 points, and 160MHz is 10 points. The scoring rules are defined as follows:

[0068]

[0069] Different scores are calculated based on whether the wireless access point is in a DFS channel. Non-DFS channels are more stable in use, so a DFS channel scores 0 points, and a non-DFS channel scores 10 points. The scoring rules are defined as follows:

[0070]

[0071] Different scores are calculated based on the wireless access point encryption type. An open network is a network without a password set, and any user can connect to and access the network. The security of this type of network is very low, and connecting to an open network is prone to attacks or leakage of personal information. A non-open network is a network that requires a password to connect to. The security of this type of network is relatively high because only users who know the password can connect to the network. Therefore, an open network is 0 points, and a non-open network is 10 points. The scoring rules are defined as follows:

[0072]

[0073] This can more intuitively show the performance of each wireless access point.

[0074] In one implementation, step M202 in this embodiment includes the following steps:

[0075] Step M2021: Calculate the received signal strength score of the accessible wireless access point according to the received signal strength of the accessible wireless access point. The calculation formula is:

[0076] f(r)=(r+r offset )*r slope ,

[0077] Where f(r) is the received signal strength score of the accessible wireless access point, r is the received signal strength of the accessible wireless access point, and r is a negative number. offset is the first constant, r slope is the second constant.

[0078] Specifically, the received signal strength indication is an optional part of the wireless transmission layer, which is used to determine the link quality and whether to increase the broadcast transmission strength. When the RSSI of a wireless access point is -85dB, the connection of the wireless access point is unreliable and has no meaning to connect. The larger the RSSI of a wireless access point, the higher the link quality. By calculating the received signal strength score of the accessible wireless access point, the quality of the wireless access point link can be intuitively evaluated, thereby helping users select a wireless access point with better performance. In this embodiment, the first constant r offst The value is 85, the second constant r slope The value is 1.2.

[0079] In one implementation, step S200 in this embodiment includes the following steps:

[0080] Step S201: according to the scene mode, setting a weight value in the scene mode for the performance indicator;

[0081] Specifically, different scene modes have different requirements for wireless access points. According to the characteristics and requirements of various scene modes, adjusting the weight of the working frequency band, WIFI standard type, bandwidth, whether it is in a DFS channel indication, encryption type, and received signal strength in the comprehensive score can help users find a more suitable wireless access point. In this embodiment, the weight configuration of Table 1 is used to assign weights to each performance parameter.

[0082] Table 1. Weight values ​​in scene mode

[0083]

[0084] Step S202: performing weighted summation on the performance indicators of each accessible wireless access point according to the weight values ​​in the scenario mode to obtain a comprehensive score of each wireless access point.

[0085] Specifically, in each scenario mode, the calculated frequency band score, standard type score, bandwidth score, whether it is in a DFS channel score, encryption type score, and received signal strength score are weighted according to Table 1 to obtain a comprehensive score of the wireless access point. The calculation formula is as follows:

[0086] S=(d(f)*f(f)+d(s)*f(s)+d(b)*f(b)+d(d)*f(d)+d(secy)*f(secy))*f(r),

[0087] Where S is the comprehensive score of the wireless access point, f(f) represents the frequency band score, f(b) represents the bandwidth score, f(s) represents the standard type score, f(d) represents the DFS channel score, f(secy) represents the encryption type score, f(r) represents the received signal strength score, d(f) is the working frequency band weight, d(s) is the WIFI standard type weight, d(b) is the bandwidth weight, d(d) is the DFS channel indication weight, and d(secy) is the encryption type weight.

[0088] For example, in the airport scene mode, device A scans the surrounding WIFI access points and tries to connect to WIFI. Device A scans 4 APs, as follows:

[0089] AP1: operates in the 5G frequency band, 80211ax, with a bandwidth of 80 MHz, in a DFS channel, using open encryption type, and an RSSI of -60 dBm.

[0090] AP2: operates in the 5G frequency band, 80211ax, with a bandwidth of 80 MHz, is not in a DFS channel, uses a non-open encryption type, and has an RSSI of -76 dBm.

[0091] AP3: works in the 2.4 GHz band, 80211n, 40 MHz bandwidth, is not in a DFS channel, uses a non-open encryption type, and has an RSSI of -46 dBm.

[0092] AP4: works in the 2.4 GHz band, 80211ax, 40 MHz bandwidth, is not in a DFS channel, uses non-open encryption type, and has an RSSI of -35 dBm.

[0093] The comprehensive score of each AP is calculated according to the comprehensive score formula of wireless access points:

[0094] AP1: S=(20%*5+20%*6+10%*6+30%*0+20%*0)*((-60+85)*1.2)=84.

[0095] AP2: S=(20%*5+20%*6+10%*6+30%*10+20%*10)*

[0096] ((-76+85)*1.2)=84.24.

[0097] AP3: S=(20%*0+20%*0+10%*3+30%*10+20%*10)*

[0098] ((-46+85)*1.2)=245.04.

[0099] AP4: S=(20%*0+20%*6+10%*3+30%*10+20%*10)*

[0100] ((-35+85)*1.2)=468.

[0101] Step S300: Select a destination wireless access point according to the comprehensive score of each wireless access point.

[0102] Specifically, according to the comprehensive score of each wireless access point, the wireless access point with the highest comprehensive score is preferentially selected as the destination wireless access point, and a WIFI link is established through the destination wireless access point to obtain the best network experience.

[0103] In one implementation, step S300 in this embodiment includes the following steps:

[0104] Step S301: sort the comprehensive scores of each wireless access point from high to low to obtain a sorted list of wireless access points;

[0105] Step S302: Select wireless access points as destination wireless access points in sequence according to the wireless access point sorting list until a connection is established.

[0106] Specifically, as described in the above example, the wireless access points are sorted from high to low according to the comprehensive score values, and the ranking list is AP4, AP3, AP2, AP1. According to the ranking list, AP4 has a score of 468 and ranks first. Device A will preferentially choose to connect to AP4. When it cannot establish a link with AP4, it will choose AP3, which ranks second, and so on, until a WIFI link is established.
