[0062] Figure 2 2 is a schematic diagram of a process 200 of a method for selecting a wireless access point AP provided by the present application. The process 200 of the method includes:

[0063] S201: Acquire key information of each of one or more wireless access points AP.

[0064] Key information includes AP performance detection data and historical connection data.

[0065] Exemplarily, the performance detection data of the AP may include the current signal strength and throughput of the AP.

[0066] The historical connection data may be performance detection data of the AP collected during a user-defined historical period, for example, the signal strength and throughput of the AP one day ago, or the duration of the AP's connection with the electronic device one day ago, the number of successful connections, the number of disconnections, etc., without limitation.

[0067] S202: Calculate values ​​of one or more parameters related to the performance indicator of each AP according to the key information.

[0068] It will be understood that the user may customize one or more parameters related to the performance indicator, which may make the performance scoring rule of the AP more flexible and ensure that the performance scoring of the AP meets the expected requirements.

[0069] In some embodiments, one or more parameters related to performance may include any one or a combination of the following:

[0070] Signal strength factor, security factor, stability factor, throughput factor.

[0071] Among them, the signal strength factor is used to reflect the strength of the wireless signal under the network conditions of the AP. The security factor is used to reflect the security of the network conditions provided by the AP. The stability factor is used to reflect the connection stability between the AP and the electronic device. The throughput factor is used to reflect the throughput performance of the AP.

[0072] Exemplarily, the one or more parameters related to the performance indicator include: a signal strength factor, a security factor, a stability factor, and a throughput factor.

[0073] In some embodiments, the expression of the signal strength factor is as shown in formula (1):

[0074]

[0075] N SignalStrength is the signal strength factor of one of the one or more APs, S value is the signal strength currently received by the electronic device from an AP, S min S is the minimum threshold of signal strength that can be detected by electronic equipment. max It is the maximum threshold of signal strength that can be detected by electronic devices.

[0076] For example, the minimum threshold of the signal strength that the electronic device can detect can be the minimum strength recognized by the electronic device as a valid signal, such as -100dBm. The maximum threshold of the signal strength that the electronic device can detect can be the best signal strength that the electronic device can receive under ideal conditions, such as 500dBm.

[0077] In some embodiments, the safety factor is expressed as follows:

[0080] Taking into account the differences in known vulnerabilities, cracking difficulties and industry standards of different security standard protocols, the corresponding security factor value can be set for each security standard protocol. As shown in formula (2), when the security standard protocol adopted by an AP is the third-generation Wi-Fi encryption protocol (WPA3), the corresponding security factor value is 1, reflecting that the security of an AP is relatively high. Similarly, when the security standard protocol adopted by an AP is the second-generation Wi-Fi encryption protocol (WPA2), the corresponding security factor value is 0.8. When the security standard protocol adopted by an AP is the Wi-Fi encryption protocol (WPA), the corresponding security factor value is 0.5. When the security standard protocol adopted by an AP is the Wired Equivalent Privacy Protocol (WEP), the corresponding security factor value is 0.2. When the security standard protocol adopted by an AP is the non-encrypted protocol (OPEN), the corresponding security factor value is 0.

[0081] It will be understood that the user can customize the value of the security factor corresponding to each security standard protocol. For example, the security factor value corresponding to WPA2 can be adjusted to 0.7, or the security factor value corresponding to WPA can be adjusted to 0.6, etc., without limitation.

[0082] In some embodiments, the stability factor is expressed as shown in formula (3):

[0083] N Stability = (W R ×R s +W T ×T a +W F ×f d ) (3)

[0084] N Stability is the stability factor of one AP among one or more APs, R s is the connection success rate factor of an AP, T a is the connection duration factor of an AP, F d is the offline frequency factor of an AP, W R is the weight corresponding to the connection success rate factor, W T is the weight corresponding to the connection duration factor, W Fis the weight corresponding to the disconnection frequency factor. The connection success rate factor is used to characterize the probability that the electronic device can successfully connect to an AP. The connection duration factor is used to characterize the probability that the connection between an electronic device and an AP can last. The disconnection frequency factor is used to characterize the probability that the connection between an electronic device and an AP will be disconnected.

[0085] Exemplarily, the connection success rate factor W R for Connection duration factor W T for Drop frequency factor W F for

[0086] In some embodiments, the expression of the connection success rate factor is as shown in formula (4):

[0087]

[0088] R s is the connection success rate factor of an AP, N success N is the number of successful connections between an electronic device and an AP. attempt The total number of times the electronic device attempts to connect to an AP;

[0089] The expression of the connection duration factor is shown in formula (5):

[0090]

[0091] T a is the connection duration factor of an AP, T duration is the duration of connection between an electronic device and an AP, T max The maximum connection time set for an electronic device to an AP;

[0092] The expression of the disconnection frequency factor is shown in formula (6):

[0093]

[0094] F d is the offline frequency factor of an AP, N drop N is the number of disconnections between an electronic device and an AP within a set period of time. max The maximum number of possible disconnections allowed between an electronic device and an AP within a set period of time.

[0095] In some embodiments, the expression of the throughput factor is as shown in equation (7):

[0096]

[0097] NThroughput is the throughput factor of one AP among one or more APs, R is the actual throughput measured by an AP, and R max is the peak throughput of an AP.

[0098] Exemplarily, the peak throughput may be determined by the wireless network standard supported by the electronic device. For example, for an electronic device supporting the 802.11n standard, R max It can be set to 600Mbps, and for electronic devices that support the 802.11ac standard, R max Can be set to 1300Mbps.

[0099] S203: For each AP, calculate a corresponding performance score according to the value of one or more parameters, and select an AP with the highest performance score as a candidate AP.

[0100] In some embodiments, the corresponding performance score is calculated based on the value of one or more parameters, including:

[0101] Gets the weight corresponding to each of one or more parameters.

[0102] The values ​​of one or more parameters are weighted and summed according to the weight corresponding to each parameter to obtain the corresponding performance score.

[0103] Exemplarily, the weights of the signal strength factor, the security factor, the stability factor, and the throughput factor may all be set to 25%.

[0104] It will be understood that the user can customize the weight of each parameter related to the performance indicator. For example, if the user pays more attention to the signal strength and security when using the network, the weight of the signal strength factor and the security factor can be increased, which can better meet the specific needs of the user.

[0105] S204: Select a target AP for the electronic device to connect to from the candidate APs according to the number of candidate APs and current application conditions.

[0106] In some embodiments, according to the number of candidate APs and current application conditions, selecting a target AP for the electronic device to connect to from the candidate APs includes any of the following:

[0107] 1) In response to the number of candidate APs being one, the candidate AP is used as a target AP.

[0108] Exemplarily, assuming that the candidate AP is unique, the candidate AP can be directly selected as the target AP, which can increase the speed at which the electronic device selects the target AP and avoid unnecessary complex calculations.

[0109] 2) In response to the number of candidate APs being greater than one, a candidate AP whose frequency band meets the current application condition is selected from the candidate APs as a target AP.

[0110] The frequency band is a frequency range used by a candidate AP, and the current application condition includes: a priority of at least one parameter among the one or more parameters.

[0111] Exemplarily, it is assumed that there are two candidate APs, using the 2.4 GHz frequency band and the 5 GHz frequency band respectively. The candidate AP of the 2.4 GHz frequency band has stronger penetration ability and wider coverage, and can provide higher stability in the network environment. The candidate AP of the 5 GHz frequency band supports higher data rate and bandwidth, and can have better throughput performance. In step S204, a more suitable target AP can be selected by considering the current application conditions and the advantages of the candidate APs of the two different frequency bands.

[0112] In some embodiments, the weight corresponding to each parameter related to the performance indicator may be sorted to determine the priority of each parameter.

[0113] For example, when the weight corresponding to the stability factor is the highest, it can be determined that the stability factor has the highest priority, so that the electronic device can select the candidate AP in the 2.4 GHz frequency band as the target AP. For another example, when the weight corresponding to the throughput factor is the highest, it can be determined that the throughput factor has the highest priority, so that the electronic device can select the candidate AP in the 5 GHz frequency band as the target AP.

[0114] It will be understood that since the signal strength factor and the safety factor are usually not highly correlated with the frequency band, in some embodiments, the one with the largest value of the highest priority parameter can be selected from the candidate APs as the target AP based on the determined highest priority parameter.

[0115] For example, when the weight corresponding to the signal strength factor is the highest, it can be determined that the signal strength factor has the highest priority, and the electronic device can also directly select a candidate with the highest signal strength factor value from the candidate APs as the target AP without considering the frequency band. For another example, when the weight corresponding to the safety factor is the highest, it can be determined that the safety factor has the highest priority, and the electronic device can also directly select a candidate with the highest safety factor value from the candidate APs as the target AP without considering the frequency band.

[0117] S301, determine whether the number of candidate APs is one, if so, execute S308, otherwise, execute S302.

[0118] S302: Determine a parameter with the highest priority among one or more parameters, and sort the candidate APs in descending order according to the parameter with the highest priority.

[0119] S303, determining whether the number of the top candidate AP in the sorting result is one, if so, executing S307, otherwise, executing S304.

[0120] S304, determining whether there is an AP whose frequency band meets the current application condition among the candidate APs at the top of the sorting results, if so, executing S306, otherwise, executing S305.

[0121] S305: Select one of the candidate APs that are ranked the highest in the ranking results as the target AP.

[0122] S306: An AP whose frequency band meets the current application condition is selected as a target AP.

[0123] S307: The candidate AP that ranks the highest in the ranking result is used as the target AP.

[0124] S308: Use the candidate AP as the target AP.

[0125] Based on the above process 300, the electronic device can always connect to the most suitable AP in different network environments and usage scenarios, thereby improving the connection performance of the wireless local area network and enhancing the user experience.
