Description
[ technical field ] A method for producing a semiconductor device
The invention relates to the technical field of computer application, in particular to a wifi network connection method, device and equipment.
[ background of the invention ]
The current common network types of wifi mainly include: OPEN, WEP, WPA/WPA2, 802.1xEAP, etc. The OPEN network is an OPEN network, can be accessed without authentication, and cannot be encrypted in the data transmission process. WEP (Wired Equivalent Privacy) performs encryption using a fixed-length and static key. WPA (Wi-Fi Protected Access) is an encryption type of a pre-shared key mode and mainly comprises two standards of WPA and WPA 2. 802.1x EAP (Extensible Authentication Protocol) requires a certificate or a user name and password for Authentication.
When a user needs to connect to a wifi network, there are two general ways: one is to find an available network scanning list through wifi scanning, and select a wifi network from the network scanning list for connection. The second is to connect the wifi network corresponding to the SSID filled by the user by adding the wifi network, including the network hiding the SSID. When a user adds a wifi network, the user needs to specify a network type, that is, one of OPEN, WEP, WPA/WPA2, and 802.1x EAP is specified as a network type to be connected, so that wifi network connection can be performed. As shown in fig. 1a, when the user selects to add a network, the SSID to be connected needs to be entered on the interface as shown in fig. 1a, and after clicking the "security" option, the network type to be connected is selected from the interface as shown in fig. 1 b. This is true for the currently mainstream Android and IOS systems. However, users with poor knowledge of wireless networks often have nothing to do, on one hand, the operation is cumbersome, and on the other hand, wifi networks cannot be connected correctly because of wrong network type input.

[ detailed description ] embodiments
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
It should be understood that the term "and/or" as used herein is merely one type of association that describes an associated object, meaning that three relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination" or "in response to a detection", depending on the context. Similarly, the phrases "if determined" or "if detected (a stated condition or event)" may be interpreted as "when determined" or "in response to a determination" or "when detected (a stated condition or event)" or "in response to a detection (a stated condition or event)", depending on the context.
Fig. 2 is a flowchart of a main method provided in the embodiment of the present invention, as shown in fig. 2, the method mainly includes the following steps:
in 201, the SSID input by the user is acquired.
In the embodiment of the present invention, when the user selects to scan the wifi network by inputting the SSID by himself, the SSID of the wifi network to which the user is to connect may be input on the interface as shown in fig. 3a by, for example, clicking "add network" as shown in fig. 1 a. In addition to entering the SSID of the wifi network to which the user is to connect on the interface shown in fig. 3a, other means for entering the SSID may be used, for example, if the user has previously connected to the wifi network of the SSID, the SSID of the wifi network may already exist in the history, and thus the user may enter the SSID by selecting the SSID in the history.
In 202, wifi network scanning is performed by using SSID to obtain a scanning result.
In this step, a wifi network matched with an SSID can be found by sending a Probe Request frame carrying the SSID; after receiving the Probe Request, the AP (access point) returns a Probe Response frame if its wifi network matches the SSID carried by the Probe Request, where the Probe Response frame includes the SSID of the wifi network and the network type information, and the SSIDs constitute a scanning result.
The wifi network obtained by scanning in this step may include two types: one is a wifi network corresponding to an AP which actively sends a broadcast frame, and the other is a wifi network corresponding to an AP which does not actively send a broadcast frame, which is also referred to as a wifi network with a hidden SSID.
After wifi network scanning is completed, the obtained scanning result may have several situations:
in the first case: if the wifi network does not exist in the scanning result, that is, no wifi network is scanned, this situation may present the prompt information that the wifi network is not scanned to the user. The user can check whether the SSID is input by mistake or input again by replacing one SSID, and the like.
In the second case: only one wifi network is included in the scanning result, in this case, the network type of the wifi network to which the user is actually connected is determined (the network type of the wifi network is already known by Probe Response during the scanning process), and the target wifi network is also determined, which is the wifi network in the scanning result.
In the third case: the scanning result contains more than two wifi networks, and in this case, the target wifi network is uncertain.
For the second case and the third case, after the scanning result is obtained, an interface for prompting the user to input the network authentication information can be displayed, and the user can input the network authentication information on the interface.
In 203, network authentication information input by the user is acquired.
In this embodiment, at least one of the following items may be provided on the interface for prompting the user to input the network authentication information:
1) passpase (password), a relatively common situation. The user enters a string of characters in a password box on the interface. The password is network authentication information used by a network type such as WEP or WPA/WPA 2.
2) The certificate information may include a CA (certificate authority) certificate, a user certificate, and the like. The digital integer is usually applied by the terminal device in advance and installed in the terminal device, and the certificate information is used for identity authentication and data encryption and decryption in the data interaction process between the terminal device and the server device. The 802.1x EAP network type often uses this network authentication information, and the user needs to select the certificate information installed in the terminal to be able to successfully access the wifi network of the 802.1x EAP type.
3) A username and password. This is also network authentication information that can be used by 802.1x EAP network types, and in some networks such as an enterprise wifi network and a campus wifi network, after the installation of a digital certificate is completed, there is no need to input certificate information each time the wifi network is logged in, but a user name and a password are required to be input for identity authentication.
4) The network authentication information input by the user can also be considered as null if no network authentication information is input, i.e. the user cancels the input of the network authentication information.
For example, assuming that the user inputs SSID "test-wifi" on the interface shown in fig. 3a, the user may further select to input network authentication information, may select to input a password, or select to input certificate information, or select to input a user name and a password on the interface shown in fig. 3b, or the user may select to directly select the determination without inputting anything.
At 204, an attempt is made to connect to at least one wifi network in the scan results using the network authentication information, wherein the automatically determined wifi network type is used in the attempt to connect to the wifi network.
If the network authentication information input by the user in the step 203 is null, it may be determined that the target wifi network type is an open network, and a wifi network belonging to the open network is determined in the scanning result and connected to the determined wifi network. If a plurality of wifi networks belonging to the open network exist in the scanning result, connection can be performed according to a preset priority order until connection is successful. For example, the connection may be made in order of high signal strength to low signal strength.
If the network authentication information input by the user in the step 203 is a password, the target type is WEP or WAP/WAP2, wifi networks belonging to the WEP and WAP/WAP2 network types can be determined from the scanning result, and then the determined wifi networks are tried to be connected one by one according to a certain priority by using the password input by the user. For example, the connection may be made in order of high signal strength to low signal strength.
For this case, there is also a preferred embodiment that the network type is first identified by the password length entered by the user, since the password length used for WEP is fixed, for example, 5 or 13 as input in ASCII code, while the password length used for WAP/WAP2 is variable. Therefore, whether the password length input by the user meets the preset WEP password length or not can be judged firstly, if not, the target wifi network type can be directly determined to be the WPA/WPA2, and the wifi network belonging to the WPA/WPA2 in the scanning result is determined and connected. Also if there are multiple wifi networks belonging to WPA/WPA2, the connection may be made according to preset priority rules, for example from high to low signal strength. If the password length input by the user is consistent with the preset WEP password length, it can be determined that the target wifi network may be the wifi network of the WEP, but may also be the wifi network of the WPA/WPA 2. In this case, the wifi network of WEP type in the scanning result may be preferentially connected, and if the connection fails, the wifi network of WPA/WPA2 may be connected again.
If the network authentication information input by the user in 203 is certificate information or a user name and a password, it may be determined that the target wifi network type is 802.1x EAP, and a wifi network belonging to 802.1x EAP is determined in the scanning result and connected. If a plurality of wifi networks belonging to 802.1x EAP are determined in the scanning result, connection may be performed according to a preset priority order until connection is successful, for example, according to an order from high to low in signal strength.
Of course, in the actual use process, other types of wifi networks may exist, or new types of wifi networks appear along with the continuous development of network technologies, but all the wifi networks can be automatically tried to be connected to the scanning result according to the network authentication information input by the user without the need of the user to select the network type based on the core mode of the present invention.
If one wifi network in the connection scanning result is successful, prompt information of successful network connection can be displayed, and the prompt information can include an SSID of the wifi network which is successfully connected. If the connection fails, prompt information of network connection failure can be displayed.
A preferred embodiment of implementing the above method of the present invention is given below by taking fig. 4 as an example, and as shown in fig. 4, the preferred embodiment may include:
in 401, the SSID input by the user is acquired.
