That is, when the electronic device is disconnected from the network, it will rescan the Wi-Fi and connect to the Wi-Fi that has been connected in the past and set to automatically connect in the Wi-Fi scan results.

However, if there is no Wi-Fi set for automatic connection among the scanned Wi-Fi, the electronic device cannot reconnect to the Wi-Fi. If the electronic device fails to reconnect to the Wi-Fi, the electronic device remains disconnected from the Wi-Fi, resulting in a poor user experience.

DETAILED DESCRIPTION

The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. The following terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features.

In the embodiments of the present application, the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

In the embodiments of the present application, "and/or" is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and/or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character "/" in this article generally indicates that the associated objects before and after are in an "or" relationship.

In the description of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "set", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

In order to better illustrate the technical solution of the present application, the following is a brief overview of the terms involved in the present application.

(1) Wireless network: A wireless network is a network that can interconnect various communication devices without wiring. Common wireless networks include Wi-Fi, Bluetooth, ZigBee, hotspots, etc.

According to the different network coverage, wireless networks can be divided into wireless wide area networks (WWAN), wireless local area networks (WLAN) and wireless metropolitan area networks (WMAN).

(2) Local Area Network (LAN): LANs generally cover an area of several thousand meters. They are easy to install, cost-effective, and easy to expand, making them widely used in various offices. LANs can realize functions such as file management, application software sharing, and printer sharing.

(3) Wide Area Network (WAN), also known as extranet or public network, is a long-distance network that connects computers in local area networks or metropolitan area networks in different regions. It usually spans a large physical range, ranging from tens of kilometers to thousands of kilometers. It can connect multiple regions, cities and countries, or span several continents and provide long-distance communications, forming an international long-distance network. A WAN is not the same as the Internet. The Internet generally refers to a public WAN.

As described in the background technology above, when the electronic device is disconnected from the Internet, it will rescan the Wi-Fi and connect to the Wi-Fi that was previously connected and set to automatically connect in the Wi-Fi scan results. However, if there is no Wi-Fi with automatic connection set in the scanned Wi-Fi, the electronic device cannot reconnect to the Wi-Fi, and the electronic device fails to reconnect to the Wi-Fi, and the electronic device will remain in the Wi-Fi disconnected state, resulting in a poor user experience.

For example, Fig. 1 shows a schematic diagram of a scenario in which a laptop computer rescans Wi-Fi. As shown in Fig. 1, the operating system of the laptop computer 100 will perform a Wi-Fi recovery connection operation. First, the laptop computer 100 will rescan Wi-Fi.

There may be multiple Wi-Fis scanned by the laptop computer 100. For example, FIG2 shows an exemplary table diagram of scanned Wi-Fis. As shown in FIG2, the scanned Wi-Fis may include Wi-Fi-A, Wi-Fi-B, Wi-Fi-C, Wi-Fi-D, Wi-Fi-E, Wi-Fi-F, and Wi-Fi-G, wherein the previously connected Wi-Fis scanned include Wi-Fi-A, Wi-Fi-B, Wi-Fi-C, Wi-Fi-E, and Wi-Fi-F. It is understandable that the previously connected Wi-Fis may be referred to as known Wi-Fis. The previously connected Wi-Fis may be Wi-Fis for which the laptop computer 100 has saved connection credentials, and the connection credentials may be a network connection password, a network account, or a network connection digital certificate. The laptop computer 100 can access the Internet through a network connection password, a network account, or a network connection digital certificate.

The automatically connectable Wi-Fi is the Wi-Fi that the laptop 100 sets as the automatically connected Wi-Fi in response to the user operation. As shown in FIG1 , the user operation may be the operation of the user clicking the automatic connection button. As shown in FIG2 , the previously connected Wi-Fi-A, Wi-Fi-B, Wi-Fi-C, Wi-Fi-E, and Wi-Fi-F scanned are not set to automatically connect. That is, the laptop 100 scans that there is no Wi-Fi that is set to automatically connect.

A Wi-Fi connection method is described below. FIG3 shows a schematic diagram of a Wi-Fi connection method of a related art. As shown in FIG3 , the process includes the following steps:

Step 301: the operating system of the notebook computer 100 detects that the Wi-Fi is disconnected, controls the notebook computer 100 to scan the Wi-Fi, and obtains the Wi-Fi scanning result.

Step 302: The operating system of the notebook computer 100 determines a known Wi-Fi and a Wi-Fi that can be automatically connected from the Wi-Fi scanning results.

Step 303: The operating system of the notebook computer 100 determines whether there is a Wi-Fi network that can be automatically connected.

When the operating system of the laptop computer 100 determines that there is a Wi-Fi that can be automatically connected, the operating system of the laptop computer 100 determines a Wi-Fi quality indicator that can automatically connect to the Wi-Fi according to the Wi-Fi parameters, and determines a target Wi-Fi based on the Wi-Fi quality indicator that can automatically connect to the Wi-Fi, that is, executes step 305. When the operating system of the laptop computer 100 determines that there is no Wi-Fi that can be automatically connected, the operating system of the laptop computer 100 controls the laptop computer 100 to keep the Wi-Fi disconnected.

Step 304: The operating system of the notebook computer 100 controls the notebook computer 100 to maintain a Wi-Fi disconnected state.

When the Wi-Fi of the laptop 100 is disconnected, the operating system will scan the network at a high frequency and regularly, so that the laptop 100 can quickly and automatically connect to the corresponding automatically connectable network when it enters the automatically connectable network range. Frequent scanning will increase the power consumption of the wireless LAN adapter in the laptop 100.

Step 305: The operating system of the notebook computer 100 determines a Wi-Fi quality indicator for automatically connecting to the Wi-Fi according to the Wi-Fi parameters, and determines a target Wi-Fi based on the Wi-Fi quality indicator for automatically connecting to the Wi-Fi.

Wi-Fi parameters include network signal strength parameters.

Step 306: The operating system of the notebook computer 100 controls the notebook computer 100 to connect to the target Wi-Fi.

The operating system of the laptop computer 100 will perform the Wi-Fi recovery connection operation according to the preset Wi-Fi recovery mechanism, such as steps 301 to 306 above. That is, the Wi-Fi that is scanned and set to automatically connect is connected. However, the previously scanned Wi-Fi-A, Wi-Fi-B, Wi-Fi-C, Wi-Fi-E, and Wi-Fi-F are not set to automatically connect. There is no Wi-Fi that is set to automatically connect among the Wi-Fi scanned by the laptop computer 100. The laptop computer 100 cannot reconnect to the Wi-Fi. The laptop computer 100 fails to reconnect to the Wi-Fi. The laptop computer 100 will still remain in the Wi-Fi disconnected state, and the user experience is poor.

In order to solve the aforementioned technical problems, an embodiment of the present application proposes a network connection method, which includes: if the electronic device detects that the wireless local area network is disconnected, the operating system of the electronic device controls the electronic device to connect to the wireless local area network according to a preset self-connection recovery mechanism; if the operating system fails to successfully connect to the wireless local area network according to the preset self-connection recovery mechanism, the electronic device determines a first target wireless local area network from the scanned candidate wireless local area networks; wherein the candidate wireless local area network is a wireless local area network for which the electronic device has saved connection credentials. Then, the electronic device is connected to the first target wireless local area network.

In the embodiment of the present application, even if the operating system of the electronic device fails to reconnect to the wireless LAN according to the preset self-connection recovery mechanism, the electronic device can select a target wireless LAN from the known wireless LANs scanned by the electronic device and control the electronic device to connect to the target wireless LAN. In this way, even if the operating system of the electronic device fails to restore the wireless LAN connection according to the preset self-connection recovery mechanism, the electronic device can automatically connect to the wireless LAN, thereby improving the user's Internet experience.

The wireless local area network here may include various wireless networks such as Wi-Fi, Bluetooth, ZigBee, hotspots, etc. In this application, the wireless local area network is mainly described by taking Wi-Fi as an example.

In the case where the Wi-Fi is Wi-Fi, when the electronic device detects that the Wi-Fi is disconnected, the operating system of the electronic device controls the electronic device to connect to the Wi-Fi according to a preset self-connection recovery mechanism; if the operating system fails to successfully connect to the Wi-Fi according to the preset self-connection recovery mechanism, the electronic device determines a first target Wi-Fi from the scanned candidate Wi-Fi; wherein the candidate Wi-Fi is a Wi-Fi for which the electronic device has saved connection credentials; and the electronic device connects to the first target Wi-Fi.

It can be understood that the preset self-connection recovery mechanism can also be called a preset Wi-Fi recovery mechanism.

For example, FIG4 is based on the content in FIG2 and shows a schematic diagram of selecting a target Wi-Fi from the scanned Wi-Fi. As shown in FIG4, the scanned Wi-Fi may include Wi-Fi-A, Wi-Fi-B, Wi-Fi-C, Wi-Fi-D, Wi-Fi-E, Wi-Fi-F and Wi-Fi-G, wherein the scanned known Wi-Fi include Wi-Fi-A, Wi-Fi-B, Wi-Fi-C, Wi-Fi-E and Wi-Fi-F. If the operating system of the laptop 100 still fails to successfully connect to the Wi-Fi according to the preset Wi-Fi recovery mechanism, a target Wi-Fi, for example, Wi-Fi-A, can be determined from Wi-Fi-A, Wi-Fi-B, Wi-Fi-C, Wi-Fi-E and Wi-Fi-F, and the laptop 100 is controlled to connect to the target Wi-Fi.

The embodiments of the present application are applied to a wireless local area network, and the following description will be given taking the wireless local area network as Wi-Fi as an example.

In order to solve the aforementioned technical problems, an embodiment of the present application proposes a Wi-Fi connection method, which includes: if the operating system of the laptop computer 100 still cannot connect to the Wi-Fi according to the preset Wi-Fi recovery mechanism, the laptop computer 100 will use the Wi-Fi recovery mechanism set in the third-party application to continue the Wi-Fi connection. Specifically, if the operating system of the laptop computer 100 still cannot connect to the Wi-Fi according to the preset Wi-Fi recovery mechanism, the operating system can send information about known networks in the scanned Wi-Fi to the third-party application. When the laptop computer 100 disconnects the Wi-Fi and the third-party application receives the information about known networks in the scanned Wi-Fi, it will determine the target Wi-Fi from the scanned known Wi-Fi and control the laptop computer 100 to connect to the target Wi-Fi. The preset Wi-Fi recovery mechanism can also be called a preset self-connection recovery mechanism.

In the embodiment of the present application, even if the operating system of the laptop computer 100 fails to reconnect to the Wi-Fi according to the preset Wi-Fi recovery mechanism, the third-party application will select a target Wi-Fi from the known Wi-Fi scanned by the laptop computer 100 and control the laptop computer 100 to connect to the target Wi-Fi. In this way, even if the operating system of the laptop computer 100 fails to restore the Wi-Fi connection according to the preset Wi-Fi recovery mechanism, it can still automatically connect to the Wi-Fi, thereby improving the user's Internet experience.

FIG6 shows a schematic diagram of a process of a Wi-Fi connection method. As shown in FIG6 , the process includes the following steps:

Step 601 : the operating system of the notebook computer 100 detects that the Wi-Fi is disconnected, and sends Wi-Fi disconnection information to a third-party application of the notebook computer 100 .

If the laptop computer 100 detects an abnormal Wi-Fi disconnection, the operating system of the laptop computer 100 can control the laptop computer 100 to connect to the wireless LAN according to the preset self-recovery mechanism; wherein the abnormal Wi-Fi disconnection includes disconnecting the Wi-Fi when no instruction from the user to disconnect the Wi-Fi is detected, that is, the abnormal Wi-Fi disconnection is a Wi-Fi disconnection triggered by a non-user Wi-Fi disconnection operation. The normal Wi-Fi disconnection includes disconnecting the Wi-Fi when an instruction from the user to disconnect the Wi-Fi is detected, that is, the normal Wi-Fi disconnection is a Wi-Fi disconnection triggered by a user Wi-Fi disconnection operation.

It is understandable that in some embodiments, a third-party application of the laptop computer 100 can apply to the operating system to register an event monitoring callback. After the operating system agrees to register the event monitoring callback, the operating system of the laptop computer 100 can send the monitored Wi-Fi information and some trigger information to the third-party application.

For example, when the laptop computer 100 detects that the Wi-Fi connection is disconnected, it will send a Wi-Fi disconnection message and a Wi-Fi disconnection reason to the third-party application. The Wi-Fi disconnection message includes a wlan_notification_acm_disconnected event. The wlan_notification_acm_disconnected event is used to indicate that the Wi-Fi connection is disconnected.

The third-party application of the laptop computer 100 can determine whether the Wi-Fi disconnection is a normal disconnection or an abnormal disconnection according to the disconnection reason. A normal disconnection refers to a Wi-Fi disconnection triggered by the laptop computer 100 in response to a user's operation of disconnecting the Wi-Fi. An abnormal Wi-Fi disconnection is a Wi-Fi disconnection triggered by an operation other than the user disconnecting the Wi-Fi. The abnormal disconnection reason can be a reason for the abnormal disconnection of the connected Wi-Fi caused by the Wi-Fi driver, wireless access point, or operating system. The wlan_notification_acm_disconnected event is used to indicate that the Wi-Fi connection is disconnected.

Step 602: The third-party application of the notebook computer 100 receives a Wi-Fi disconnection message.

Step 603: The operating system of the notebook computer 100 controls the notebook computer 100 to scan Wi-Fi and obtain the Wi-Fi scanning result.

When the operating system of the notebook computer 100 detects that the Wi-Fi is disconnected, a mechanism for reconnecting to the Wi-Fi can be started. First, the notebook computer 100 can scan the Wi-Fi, try to obtain the Wi-Fi that can be reconnected, and obtain the Wi-Fi scanning result.

Step 604: The operating system of the notebook computer 100 determines known Wi-Fi and automatically connectable Wi-Fi from the Wi-Fi scanning results.

The laptop computer 100 may or may not scan Wi-Fi. If the laptop computer 100 cannot scan Wi-Fi, the number of Wi-Fi scanned in the Wi-Fi scan result is 0; if the laptop computer 100 scans Wi-Fi, the number of Wi-Fi scanned in the Wi-Fi scan result is at least 1. When the number of Wi-Fi scanned in the Wi-Fi scan result is greater than or equal to 1, the laptop computer 100 can determine known Wi-Fi and Wi-Fi that can be automatically connected from the Wi-Fi scan result.

It is understandable that the number of known Wi-Fi in the Wi-Fi scan result may be 0, or may be greater than or equal to 1, and the number of automatically connectable Wi-Fi may be 0, or may be greater than or equal to 1.

It is known that Wi-Fi can also be called a candidate wireless local area network, from which the notebook computer 100 can select a network to connect.

The operating system of the notebook computer 100 stores the known Wi-Fi and automatically connectable Wi-Fi in a period of time before the current time. In this way, the operating system of the notebook computer 100 can match the Wi-Fi in the Wi-Fi scan result with the known Wi-Fi and automatically connectable Wi-Fi stored in the operating system of the notebook computer 100, and determine the known Wi-Fi and automatically connectable Wi-Fi from the Wi-Fi scan result.

The known Wi-Fi networks within a period of time before the current time stored in the operating system of the notebook computer 100 can be displayed on the display screen of the notebook computer 100 .

For example, FIG7 shows a schematic diagram of a network and Internet user interface of an operating system of a laptop computer 100. As shown in FIG7, the network and Internet user interface of the operating system of the laptop computer 100 displays a management known network entry. In response to the user opening the management known network entry with a cursor, the laptop computer 100 can display known Wi-Fis within a period of time before the current time.

The Wi-Fi scan result can be displayed on the display screen of the laptop computer 100. The network and Internet user interface of the operating system of the laptop computer 100 displays available network entries. In response to the user's operation of opening the display available network entry with a cursor, the laptop computer 100 can display the Wi-Fi scan result.

Step 605: The operating system of the notebook computer 100 determines whether there is a Wi-Fi network that can be automatically connected.

If the number of automatically connected Wi-Fi is 0, the notebook computer 100 determines that there is no automatically connected Wi-Fi; if the number of automatically connected Wi-Fi is greater than or equal to 1, the notebook computer 100 determines that there is an automatically connected Wi-Fi.

When the laptop computer 100 determines that there is a Wi-Fi that can be automatically connected, the operating system of the laptop computer 100 determines the Wi-Fi quality indicator of the Wi-Fi that can be automatically connected according to the Wi-Fi parameters, and determines the target Wi-Fi based on the Wi-Fi quality indicator of the Wi-Fi that can be automatically connected, that is, executing step 611. When the laptop computer 100 determines that there is no Wi-Fi that can be automatically connected, the laptop computer 100 controls the laptop computer 100 to keep the Wi-Fi disconnected, and sends the information of the known Wi-Fi in the Wi-Fi scan result to the third-party application, that is, executing step 606.

Step 606: The operating system of the notebook computer 100 controls the notebook computer 100 to keep the Wi-Fi disconnected state, and sends the information of the known Wi-Fi in the Wi-Fi scan result to the third-party application.

The operating system of the notebook computer 100 can send the information about the known Wi-Fi in the Wi-Fi scan result to the third-party application of the notebook computer 100. In this way, the third-party application can receive the information about the known Wi-Fi in the Wi-Fi scan result sent by the operating system, and when receiving the information about the known Wi-Fi in the Wi-Fi scan result sent by the operating system, execute the Wi-Fi recovery mechanism in the third-party application and perform the Wi-Fi recovery connection operation.

It can be understood that in the related art, when the laptop computer 100 is disconnected from the network, the operating system of the laptop computer 100 will perform the Wi-Fi recovery connection operation according to the preset Wi-Fi recovery mechanism. The third-party application will only execute the Wi-Fi recovery mechanism in the third-party application and perform the Wi-Fi recovery connection operation when it receives the Wi-Fi scan result sent by the operating system with the information of the known Wi-Fi, instead of executing the Wi-Fi recovery mechanism in the third-party application when the Wi-Fi is disconnected at the beginning of the laptop computer 100. In this way, the conflict between the Wi-Fi recovery mechanism in the third-party application and the Wi-Fi recovery mechanism in the operating system can be avoided.

When the Wi-Fi of the laptop computer 100 is disconnected and the wireless service in the operating system determines that there is a known Wi-Fi, the operating system can send information about the known Wi-Fi in the Wi-Fi scan result to the third-party application, and the information about the known Wi-Fi in the Wi-Fi scan result includes a wlan_notification_acm_network_available event; wherein the wlan_notification_acm_network_available event is used to indicate that there is a known Wi-Fi in the Wi-Fi scan result.

It is understandable that in some embodiments, a third-party application of the laptop computer 100 can apply to the operating system to register an event monitoring callback. After the operating system agrees to register the event monitoring callback, the operating system of the laptop computer 100 can send the monitored Wi-Fi information and some trigger information to the third-party application.

For example, the laptop computer 100 can send information about known Wi-Fi in the Wi-Fi scan results to a third-party application if it determines that there is no Wi-Fi that can be automatically connected, or send information about known Wi-Fi in the Wi-Fi scan results to a third-party application if the target Wi-Fi connection fails.

It can be understood that in some embodiments, after the notebook computer 100 is turned on and the third-party application of the notebook computer 100 is opened, the software has been running in the background, and the software registers an event monitoring callback with the operating system when it is just started.

It is understandable that in some embodiments, when the number of known Wi-Fi networks is greater than 0, the operating system of the laptop computer 100 sends information about known Wi-Fi networks in the Wi-Fi scan result to the third-party application of the laptop computer 100. In this way, the third-party application can receive the information about known Wi-Fi networks in the Wi-Fi scan result sent by the operating system, and when receiving the information about known Wi-Fi networks in the Wi-Fi scan result sent by the operating system, the third-party application executes the Wi-Fi recovery mechanism in the third-party application and performs the Wi-Fi recovery connection operation.

If the number of known Wi-Fis is 0, the operating system of the laptop computer 100 still sends the information of the known Wi-Fis in the Wi-Fi scan result to the third-party application of the laptop computer 100. In this way, even if the third-party application receives the information of the known Wi-Fis in the Wi-Fi scan result sent by the operating system, and executes the Wi-Fi recovery mechanism in the third-party application, the reconnection to Wi-Fi will fail because the number of known Wi-Fis is 0, and the power consumption of the operating system of the laptop computer 100 in sending the information of the known Wi-Fis in the Wi-Fi scan result to the third-party application of the laptop computer 100 will be wasted. Therefore, the operating system of the laptop computer 100 sends the information of the known Wi-Fis in the Wi-Fi scan result to the third-party application of the laptop computer 100 only when the number of known Wi-Fis is greater than 0. In this way, unnecessary Wi-Fi connection power consumption of the laptop computer 100 can be reduced.

Step 607: The third-party application of the notebook computer 100 receives information about known Wi-Fi in the Wi-Fi scanning result sent by the operating system.

Step 608: The third-party application of the notebook computer 100 determines a known Wi-Fi from the Wi-Fi scanning result.

The operating system of the laptop computer 100 stores the known Wi-Fi in a period of time before the current time. When the third-party application of the laptop computer 100 receives the information of the known Wi-Fi in the Wi-Fi scanning result sent by the operating system, the known Wi-Fi stored in the operating system of the laptop computer 100 can be obtained from the operating system of the laptop computer 100. In this way, the third-party application of the laptop computer 100 can match the Wi-Fi in the Wi-Fi scanning result with the known Wi-Fi obtained from the operating system of the laptop computer 100, and determine the known Wi-Fi from the Wi-Fi scanning result.

Step 609 : The third-party application of the notebook computer 100 determines the best Wi-Fi from the known Wi-Fi.

It can be understood that the quality of Wi-Fi depends to a certain extent on various quality indicators of Wi-Fi, and various quality indicators of Wi-Fi can be parameter values of Wi-Fi parameters. In order to improve the user experience, the laptop 100 can select a better quality Wi-Fi to be connected according to the Wi-Fi parameters. Specifically, in some embodiments, the laptop 100 can determine the Wi-Fi quality indicators of known Wi-Fi according to the Wi-Fi parameters, rank the connection priorities according to the Wi-Fi quality indicators, and determine the optimal Wi-Fi based on the ranked connection priorities.

Specifically, Figure 8 shows a schematic diagram of a process of optimal Wi-Fi confirmation. As shown in Figure 8, the process includes the following steps:

Step 801: The third-party application of the notebook computer 100 determines the Wi-Fi quality indicator of each Wi-Fi among the known Wi-Fi according to the Wi-Fi parameters of the Wi-Fi among the known Wi-Fi.

The Wi-Fi parameter may include at least one, and the Wi-Fi quality indicator may be the sum of at least one Wi-Fi parameter score. The Wi-Fi parameter may include any one or more combinations of a network signal strength parameter, a network signal quality parameter, a Wi-Fi frequency band, a Wi-Fi protocol, a Wi-Fi connection rate, and Wi-Fi protocol security.

The following uses Wi-Fi parameters including network signal quality parameters, Wi-Fi frequency band, Wi-Fi protocol, Wi-Fi connection rate, and Wi-Fi protocol security as an example to illustrate the quality indicator determination solution.

For example, a schematic diagram of a Wi-Fi quality indicator is shown in Figure 9. As shown in Figure 9, the Wi-Fi parameters may include Wi-Fi signal quality parameters, Wi-Fi frequency band parameters, Wi-Fi protocol parameters, Wi-Fi connection rate parameters, and Wi-Fi protocol security parameters, and the Wi-Fi quality indicator may be the sum of the Wi-Fi signal quality parameter score, the Wi-Fi frequency band parameter score, the Wi-Fi protocol parameter score, the Wi-Fi connection rate parameter score, and the Wi-Fi protocol security parameter score.

The following is an example of a scoring standard for Wi-Fi signal quality parameters, Wi-Fi frequency band parameters, Wi-Fi protocol parameters, Wi-Fi connection rate parameters, and Wi-Fi protocol security parameters.

Table 1 shows an exemplary table of signal quality parameter scores.

Table 1

As shown in Table 1, if the signal quality parameter is in the range of greater than 0 and less than 30, the Wi-Fi signal quality parameter score is 0; if the signal quality parameter is in the range of greater than or equal to 30 and less than 50, the Wi-Fi signal quality parameter score is 20; if the signal quality parameter is in the range of greater than or equal to 50 and less than 70, the Wi-Fi signal quality parameter score is 60; if the signal quality parameter is in the range of greater than or equal to 70 and less than or equal to 100, the Wi-Fi signal quality parameter score is 80.

Table 2 shows an exemplary table of Wi-Fi frequency band scores.

Table 2

As shown in Table 2, if the Wi-Fi i frequency band parameter is 2.4 GHz, the Wi-Fi i frequency band score is 20; if the Wi-Fi i frequency band parameter is 5 GHz, the Wi-Fi i frequency band score is 50.

Table 3 shows an exemplary table of Wi-Fi protocol type parameter scores.

Table 3

As shown in Table 3, if the Wi-Fi protocol type parameter is b/a/g/n, the Wi-Fi protocol type parameter score is 0; if the Wi-Fi protocol type parameter is ac, the Wi-Fi protocol type parameter score is 5; if the Wi-Fi protocol type parameter is ax, the Wi-Fi protocol type parameter score is 10; if the Wi-Fi protocol type parameter is be, the Wi-Fi protocol type score is 15.

Table 4 shows an exemplary table of Wi-Fi connection rate parameter scores.

Table 4

As shown in Table 4, if the Wi-Fi connection rate parameter is in the range of greater than or equal to 0 and less than 287, the Wi-Fi connection rate parameter score is 0; if the Wi-Fi connection rate parameter is in the range of greater than or equal to 287 and less than 574, the Wi-Fi connection rate parameter score is 5; if the Wi-Fi connection rate parameter is in the range of greater than or equal to 574 and less than 1201, the Wi-Fi connection rate parameter score is 10; if the Wi-Fi connection rate parameter is greater than or equal to 1201, the Wi-Fi connection rate parameter score is 15.

Table 5 shows an exemplary table of Wi-Fi protocol security scores.

Table 5

As shown in Table 5, if the Wi-Fi protocol security parameter is secure, the Wi-Fi protocol security parameter score is 40; if the Wi-Fi protocol security parameter is open, the Wi-Fi protocol security parameter score is 0.

In some embodiments, the known Wi-Fi may be a Wi-Fi whose signal strength is greater than or equal to a preset signal strength threshold. The preset signal strength threshold may be -75dbm.

In some embodiments, the laptop computer 100 can obtain Wi-Fi parameter contents such as Wi-Fi protocol type parameters, Wi-Fi connection rate parameters, Wi-Fi signal quality parameters, Wi-Fi signal strength parameters, and Wi-Fi security parameters for connecting to Wi-Fi through some public interfaces provided by the operating system.

1) Through the operating system public interface: WlanQueryInterface function, set the parameter OpCode to wlan_intf_opcode_current_connection, which can be used to obtain the Wi-Fi protocol type parameters, Wi-Fi connection rate parameters, Wi-Fi signal quality parameters, and Wi-Fi security parameters of the current Wi-Fi connection.

2) Through the operating system public interface: WlanQueryInterface function, set the parameter OpCode to wlan_intf_opcode_channel_number, which can be used to obtain the channel of the current Wi-Fi connection, and the channel can be mapped to the frequency band parameters.

3) Through the operating system public interface: WlanQueryInterface function, set the parameter OpCode to wlan_intf_opcode_rssi, which can be used to obtain the Wi-Fi signal strength parameters of the currently connected Wi-Fi.

Step 802: The third-party application of the notebook computer 100 ranks the connection priority of each Wi-Fi among the known Wi-Fi according to the Wi-Fi quality indicator of each Wi-Fi among the known Wi-Fi.

Specifically, in some embodiments, the laptop computer 100 may rank the Wi-Fi quality indicators of each Wi-Fi in the known Wi-Fi in order from high to low, and then the laptop computer assigns connection priorities to the Wi-Fi in order from high to low according to the ranking of the Wi-Fi quality indicators from high to low.

Step 803: The third-party application of the notebook computer 100 determines the optimal Wi-Fi based on the ranking of the connection priority of each Wi-Fi among the known Wi-Fis.

The notebook computer 100 may determine the optimal Wi-Fi network from among the known Wi-Fi networks, the Wi-Fi network having the highest connection priority among the Wi-Fi networks.

For example, as shown in FIG. 10 , the notebook computer 100 may determine Wi-Fi-F as the optimal Wi-Fi.

The network can be divided into wide area network, local area network and metropolitan area network according to the different network coverage. Broadening the Internet access range of electronic devices can improve the user's Internet experience. In some other embodiments, the electronic device can preferentially connect to the network with the ability to communicate with the wide area network among the scanned Wi-Fi, and the Wi-Fi with a higher connection priority. The connection priority is the connection priority determined according to the above scheme.

Specifically, Figure 11 shows a schematic diagram of a process of optimal Wi-Fi confirmation. As shown in Figure 11, the process includes the following steps:

Step 1101 : The third-party application of the notebook computer 100 determines whether the known Wi-Fi networks include a Wi-Fi network capable of communicating with a wide area network.

If the known Wi-Fis include at least one Wi-Fi having the capability to communicate with a wide area network, a Wi-Fi quality indicator of the Wi-Fi having the capability to communicate with a wide area network among the known Wi-Fis is determined according to the Wi-Fi parameters of the Wi-Fi having the capability to communicate with a wide area network among the known Wi-Fis, that is, step 1102 is executed; if the known Wi-Fis do not include a Wi-Fi having the capability to communicate with a wide area network, a Wi-Fi quality indicator of the Wi-Fi having no capability to communicate with a wide area network among the known Wi-Fis is determined according to the Wi-Fi parameters of the Wi-Fi having no capability to communicate with a wide area network among the known Wi-Fis, that is, step 1105 is executed.

In some embodiments, the laptop computer 100 can determine whether the currently connected Wi-Fi is a Wi-Fi capable of communicating with a wide area network by detecting a public server or the like. For example, the laptop computer 100 sends an Internet Control Message Protocol (ICMP) request to a search engine domain name system server, and the laptop computer 100 receives an ICMP response to determine whether the Wi-Fi is a Wi-Fi capable of communicating with a wide area network; the laptop computer 100 can also send an HTTP request to a cloud server for detecting the connectivity of the laptop computer 100, and the laptop computer 100 receives an HTTP response, and determines whether the Internet is available based on the HTTP response code. If the Internet is available, it is determined that the Wi-Fi is a Wi-Fi capable of communicating with a wide area network.

In some embodiments, the known Wi-Fi may be a Wi-Fi whose signal strength is greater than or equal to a preset signal strength threshold. The preset signal strength threshold may be -75dbm.

Step 1102: The third-party application of the notebook computer 100 determines a Wi-Fi quality indicator of the known Wi-Fi capable of communicating with the wide area network according to the Wi-Fi parameters of the known Wi-Fi capable of communicating with the wide area network.

The Wi-Fi quality indicator of the Wi-Fi capable of communicating with the wide area network is the same as the determination scheme of the aforementioned Wi-Fi quality indicator, which is not repeated here.

Step 1103: The third-party application of the notebook computer 100 ranks the connection priorities of the known Wi-Fi networks capable of communicating with the wide area network according to the Wi-Fi quality indicators of the known Wi-Fi networks capable of communicating with the wide area network.

The connection priority ranking of the Wi-Fi capable of communicating with the wide area network is the same as the connection priority ranking scheme of the aforementioned Wi-Fi connection priority ranking, and will not be repeated here.

Step 1104 : The third-party application of the notebook computer 100 determines the optimal Wi-Fi based on the ranking of the connection priorities of all Wi-Fis among the known Wi-Fis that have the ability to communicate with the wide area network.

The determination of the optimal Wi-Fi among the Wi-Fis capable of communicating with the wide area network is the same as the aforementioned determination scheme of the optimal Wi-Fi, which will not be described in detail here.

Step 1105: The third-party application of the notebook computer 100 determines the Wi-Fi quality indicator of the known Wi-Fi network that does not have the ability to communicate with the wide area network according to the Wi-Fi parameters of the known Wi-Fi network that does not have the ability to communicate with the wide area network.

The Wi-Fi quality indicator of the Wi-Fi that does not have the ability to communicate with the wide area network is the same as the determination scheme of the aforementioned Wi-Fi quality indicator, which is not repeated here.

Step 1106 : The third-party application of the notebook computer 100 ranks the connection priorities of the known Wi-Fi networks that do not have the ability to communicate with the wide area network according to the Wi-Fi quality indicators of the known Wi-Fi networks that do not have the ability to communicate with the wide area network.

The connection priority ranking of Wi-Fi that does not have the ability to communicate with a wide area network is the same as the connection priority ranking scheme of the aforementioned Wi-Fi connection priority ranking, and will not be repeated here.

Step 1107 : The third-party application of the notebook computer 100 determines the optimal Wi-Fi based on the ranking of the connection priorities of all Wi-Fis that do not have the ability to communicate with the wide area network among the known Wi-Fis.

The Wi-Fi quality indicator of the Wi-Fi that does not have the ability to communicate with the wide area network is the same as the determination scheme of the aforementioned Wi-Fi quality indicator, which is not repeated here.

It is understandable that the laptop computer 100 can also determine the Wi-Fi quality index of the known Wi-Fi according to the Wi-Fi parameters, rank the connection priorities according to the Wi-Fi quality index, and determine the optimal Wi-Fi based on the ranked connection priorities. The specific solution is the same as the judgment criteria of the above-mentioned target network, and will not be repeated again.

In the embodiment of the present application, the optimal Wi-Fi may be the Wi-Fi with the highest connection priority.

In this step, various solutions for the third-party application of the notebook computer 100 to determine the optimal Wi-Fi from known Wi-Fi can be collectively referred to as a first approach.

In the embodiment of the present application, in this step, the optimal Wi-Fi is the Wi-Fi with the highest connection priority determined in the first manner. The optimal Wi-Fi and other target wireless local area networks may also be referred to as first target local area networks.

Step 610: The third-party application of the notebook computer 100 controls the notebook computer 100 to connect to the optimal Wi-Fi.

For example, FIG12 shows a schematic diagram of the ranking of Wi-Fi connection priorities of a known Wi-Fi. As shown in FIG12, known Wi-Fi includes Wi-Fi-A, Wi-Fi-B, Wi-Fi-C, Wi-Fi-E, and Wi-Fi-F. If the Wi-Fi quality indicators obtained by Wi-Fi-A, Wi-Fi-B, Wi-Fi-C, Wi-Fi-E, and Wi-Fi-F according to the quality indicator determination scheme in the third-party application are 90, 110, 105, 95, and 150, respectively, then the connection priority ranking of Wi-Fi is: Wi-Fi-A is ranked fifth in connection priority, Wi-Fi-B is ranked second in connection priority, Wi-Fi-C is ranked third in connection priority, Wi-Fi-E is ranked fourth in connection priority, and Wi-Fi-F is ranked first in connection priority. Wi-Fi-F is the best Wi-Fi among the known Wi-Fi. The third-party application of the laptop computer 100 controls the laptop computer 100 to connect to Wi-Fi-F.

In some embodiments, if the laptop computer 100 fails to connect to the optimal Wi-Fi, it may also connect to the suboptimal Wi-Fi. For example, the suboptimal Wi-Fi may be the Wi-Fi with the second highest connection priority.

Step 611: The operating system of the notebook computer 100 determines a Wi-Fi quality indicator for automatically connecting to the Wi-Fi according to the Wi-Fi parameters, and determines a target Wi-Fi based on the Wi-Fi quality indicator for automatically connecting to the Wi-Fi.

In this step, the operating system of the laptop computer 100 determines the Wi-Fi quality indicator that can automatically connect to the Wi-Fi based on the Wi-Fi parameters, and the scheme for determining the target Wi-Fi based on the Wi-Fi quality indicator that can automatically connect to the Wi-Fi can be collectively referred to as the second method. The scheme for determining the target Wi-Fi in the second method is the same as that in the first method, but the network parameters in the second method are different from the network parameters in the first method. The network parameters in the first method include any combination of network signal strength parameters, network signal quality parameters, network frequency band parameters, network protocol parameters, network connection rate, or network protocol security parameters; the network parameters in the second method include network signal strength parameters.

In the embodiment of the present application, in this step, the target Wi-Fi is the Wi-Fi with the first connection priority determined in the second manner. The target Wi-Fi and other target wireless local area networks may also be referred to as second target local area networks.

For example, FIG10 shows a schematic diagram of the ranking of Wi-Fi connection priorities that can automatically connect to Wi-Fi. As shown in FIG10, known Wi-Fi includes Wi-Fi-A, Wi-Fi-B, Wi-Fi-C, Wi-Fi-E, and Wi-Fi-F. The Wi-Fi that can automatically connect includes Wi-Fi-B, Wi-Fi-C, and Wi-Fi-F. The total Wi-Fi quality scores obtained by Wi-Fi-B, Wi-Fi-C, and Wi-Fi-F in the second way are 110, 105, and 150, respectively. Then the connection priority ranking of Wi-Fi is: Wi-Fi-B is ranked second in connection priority, Wi-Fi-C is ranked third in connection priority, and Wi-Fi-F is ranked first in connection priority.

Step 612: The operating system of the notebook computer 100 controls the notebook computer 100 to connect to the target Wi-Fi.

For example, the operating system of the notebook computer 100 controls the notebook computer 100 to connect to Wi-Fi-F.

In the related art, the operating system of the laptop computer 100 stores known Wi-Fis that can automatically connect to Wi-Fi. If these known Wi-Fis that can automatically connect to Wi-Fi are not successfully connected to, and there are other known Wi-Fis that can be connected, the Wi-Fi connection is in a disconnected state, and the operating system will scan regularly at a high frequency so that it can quickly and automatically connect to these known Wi-Fis that can automatically connect to Wi-Fis when entering the range of these known Wi-Fis that can automatically connect to Wi-Fis. Frequent scanning will increase the power consumption of the wireless Wi-Fi adapter in the laptop computer 100. In the implementation of this application, the laptop computer 100 can connect to these known Wi-Fis, and the operating system will no longer trigger these scans, thereby reducing the power consumption of the laptop computer 100.

Step 613: The operating system of the notebook computer 100 determines whether the target Wi-Fi connection is successful.

The laptop computer 100 determines whether the target Wi-Fi is successfully connected. If the target Wi-Fi is successfully connected, in order to improve the user experience and allow the user to use Wi-Fi with better quality, the laptop computer 100 can also determine whether the target Wi-Fi is the best Wi-Fi among the known Wi-Fi. First, the operating system of the laptop computer 100 sends the information of successful Wi-Fi connection to the third-party application, so that the third-party application can determine the best Wi-Fi from the known Wi-Fi, that is, execute step 614. If the target Wi-Fi connection fails, the laptop computer 100 is controlled to keep the Wi-Fi disconnected state, and the information of the known Wi-Fi in the Wi-Fi scan result is sent to the third-party application, that is, execute step 606.

In some embodiments, if the laptop computer 100 fails to connect to the target Wi-Fi, it can also connect to the suboptimal Wi-Fi, for example, the suboptimal Wi-Fi can be the Wi-Fi with the second highest connection priority. In the case that the laptop computer 100 fails to connect to the suboptimal Wi-Fi, the laptop computer 100 is controlled to keep the Wi-Fi disconnected, and the information of the known Wi-Fi in the Wi-Fi scan result is sent to the third-party application; in the case that the laptop computer 100 successfully connects to the suboptimal Wi-Fi, the operating system of the laptop computer 100 sends the information of the successful Wi-Fi connection to the third-party application, so that the third-party application can determine the optimal Wi-Fi from the known Wi-Fi.

Step 614: The operating system of the notebook computer 100 sends a message indicating that the Wi-Fi connection is successful to the third-party application.

Step 615: the third-party application of the notebook computer 100 receives the Wi-Fi connection success information sent by the third-party application, and the third-party application of the notebook computer 100 determines the known Wi-Fi from the Wi-Fi scanning result.

In this step, the technical solution for determining the known Wi-Fi from the Wi-Fi scanning result is the same as the technical solution in step 608, which will not be repeated here.

It is understandable that in some embodiments, a third-party application of the laptop computer 100 can apply to the operating system to register an event monitoring callback. After the operating system agrees to register the event monitoring callback, the operating system of the laptop computer 100 can send the monitored Wi-Fi information and some trigger information to the third-party application.

For another example, when the laptop computer 100 detects that the Wi-Fi connection is successful, it will send information about the successful Wi-Fi connection to the third-party application. The information about the successful Wi-Fi connection includes a wlan_notification_acm_connection_complete event. The wlan_notification_acm_connection_complete event is used to indicate that the Wi-Fi connection is successful.

Step 616: The third-party application of the notebook computer 100 determines the best Wi-Fi from the known Wi-Fi.

The technical solution of this step is the same as that in step 609 and will not be repeated here.

In this step, various solutions for the third-party application of the notebook computer 100 to determine the optimal Wi-Fi from known Wi-Fi can be collectively referred to as a first approach.

In the embodiment of the present application, in this step, the optimal Wi-Fi is the Wi-Fi with the highest connection priority determined in the first manner. The optimal Wi-Fi and other target wireless local area networks may also be referred to as third target local area networks.

Step 617: The third-party application of the notebook computer 100 determines whether the target Wi-Fi is the best Wi-Fi among the known Wi-Fi.

The laptop computer 100 determines whether the target Wi-Fi is the best Wi-Fi among the known Wi-Fis. If the target Wi-Fi is the best Wi-Fi among the known Wi-Fis, the process ends. If the target Wi-Fi is not the best Wi-Fi among the known Wi-Fis, the laptop computer 100 is further controlled to connect to the best Wi-Fi among the known Wi-Fis, that is, step 618 is executed.

For example, FIG12 shows a schematic diagram of ranking Wi-Fi connection priorities of a known Wi-Fi. As shown in FIG12, known Wi-Fi includes Wi-Fi-A, Wi-Fi-B, Wi-Fi-C, Wi-Fi-E, and Wi-Fi-F. If the Wi-Fi quality indicators obtained by Wi-Fi-A, Wi-Fi-B, Wi-Fi-C, Wi-Fi-E, and Wi-Fi-F according to the quality indicator determination scheme in the third-party application are 90, 110, 105, 95, and 150, respectively, then the connection priority ranking of Wi-Fi is: Wi-Fi-A is ranked fifth in connection priority, Wi-Fi-B is ranked second in connection priority, Wi-Fi-C is ranked third in connection priority, Wi-Fi-E is ranked fourth in connection priority, and Wi-Fi-F is ranked first in connection priority. Wi-Fi-F is the best Wi-Fi among the known Wi-Fi. If the laptop computer 100 determines that Wi-Fi-F is the best Wi-Fi among the known Wi-Fi: Wi-Fi-F, then the connection priority ranking is ended.

As another example, FIG13 shows a schematic diagram of the ranking of Wi-Fi connection priorities of a Wi-Fi that can be automatically connected. As shown in FIG13 , it is known that Wi-Fi includes Wi-Fi-A, Wi-Fi-B, Wi-Fi-C, Wi-Fi-E, and Wi-Fi-F. The Wi-Fi that can be automatically connected are Wi-Fi-B and Wi-Fi-C. The Wi-Fi quality indicators obtained by Wi-Fi-B and Wi-Fi-C according to the quality indicator determination scheme in the operating system are 110 and 105 respectively. Then, the connection priority ranking of Wi-Fi is: Wi-Fi-B is ranked first in connection priority, and Wi-Fi-C is ranked second in connection priority. Wi-Fi-B is the target Wi-Fi.

The laptop computer 100 determines that Wi-Fi-B is not the best Wi-Fi among the known Wi-Fis: Wi-Fi-F, and further controls the laptop computer 100 to connect to the best Wi-Fi among the known Wi-Fis: Wi-Fi-F, that is, executes step 618 .

In some embodiments, if the laptop computer 100 fails to connect to the optimal Wi-Fi, it may also connect to the suboptimal Wi-Fi. For example, the suboptimal Wi-Fi may be the Wi-Fi with the second highest connection priority.

Step 618: The third-party application of the notebook computer 100 controls the notebook computer 100 to connect to the optimal Wi-Fi.
