Description

Method and system for detecting cause of WiFi connection failure

technical field

The present invention relates to WiFi connection technology, in particular to a method and system for detecting the cause of WiFi connection failure.

Background technique

With the development of mobile communication technology and the popularization of Wi-Fi technology, people often connect to hotspots to surf the Internet through Wi-Fi. Based on security considerations, most hotspots are encrypted, and connection to hotspots requires identity authentication. The authentication method widely used at present is WPA. The full name of WPA is Wi-Fi Protected Access. It is a standard-based interoperable WLAN security enhancement solution. WPA can ensure that the data of WLAN users is protected, and only authorized network users can access the WLAN network. wpa_supplicant is the implementation of WPA in software. It is an open source project. Currently, Android uses wpa_supplicant to implement the WPA protocol.

In the prior art, the normal process of connecting to an AP protected by WPA is as follows: scan to the AP, initiate a connection request; associate to the AP (Wireless Access Point (WirelessAccessPoint)), initiate an identity authentication request (at this stage, only identity Authentication-related data frames, cannot access the external network); if the authentication fails, the connection is disconnected; if the identity authentication passes, the network connection is established. (At this time, the mobile phone can access the external network.)

The reason for the authentication failure may be that the connection timed out due to network congestion, or the password entered by the user may be wrong. This distinction is not made on current mobile terminals, which is likely to mislead users. Therefore, it is necessary to distinguish the reasons for identity authentication failures and improve user experience.

detailed description

The gist of the present invention is to overcome the deficiencies of the prior art and provide a method for detecting the cause of a WiFi connection failure, which informs the user whether the cause of the connection failure is a connection timeout caused by network congestion or a password error. The following will describe in detail with reference to the accompanying drawings in conjunction with the embodiments, so as to further explain the technical features and advantages of the present invention.

The flow chart of the method of the present invention is shown in FIG. 1 , a method for detecting the cause of a WiFi connection failure includes the following steps.

S0. Preset a connection timeout alarm clock, associate the connection timeout alarm clock with the wireless access point connection request, preset the response time of the connection request, if the response is within the preset time, it is determined that the network connection is normal, if it is within the preset time If there is no response within a certain period of time, it is determined that the network connection is abnormal. Different from the prior art, the present invention sets a connection timeout alarm clock, for example, timing for one minute. If the authentication completion message is not received within one minute, it is determined that the network connection is abnormal and the connection cannot be completed. After receiving the identity authentication response from the wireless access point, it is determined that the network connection is normal, and the user can normally perform identity authentication, such as inputting a password and other operations.

S1. The mobile terminal scans the wireless access point (or AP point for short) in real time, and sends a connection request when the wireless access point is scanned; in real life, it is possible that the environment where the user's mobile terminal is located may include multiple wireless access point, then when there are multiple wireless access points, scan the wireless access points one by one, and repeat until a wireless access point that can be connected is found. If the first scanned wireless access point can be connected and surf the Internet normally, then stop scanning other wireless access points.

S2. Connect to the wireless access point, initiate an identity authentication request, and set a connection timeout alarm clock for timing; at this time, when the mobile terminal initiates an identity authentication request, the timeout alarm clock is set for timing, such as timing for one minute, of course, the user can Adjust the length of the timing according to the actual situation, and improve the user experience by adjusting the length of the timing.

S3. After receiving an identity authentication response from the wireless access point within a preset time, it is determined that the network connection is normal.

As a preferred embodiment of the present invention, step 3 of the present invention specifically includes:

Step 301. Receive the identity authentication response from the wireless access point within the preset time, and obtain the response information of the wireless access point; generally, the identity authentication response returned by the wireless access point is that the current network is normal, and there is no busy or Blocking, that is, providing an interface where user account numbers and passwords can be entered;

Step 302. According to the response information of the wireless access point, report the identity authentication information; the user inputs the user account and password according to the wireless access point, and reports the identity authentication information;

Step 303. Receive the identity authentication result reported by the wireless access point in real time; during this process, the device of the wireless access point judges the user account and password to determine whether the input is correct;

Step 304. If the identity authentication is passed, a network connection is established, and if the identity authentication fails, the user interface displays a password error. If the user account number and password are correct, a network connection is established, and if the user account number and password are wrong, the password error will be displayed on the user interface of the mobile terminal to inform the user that the reason for the connection failure is the connection timeout caused by network congestion or the password error.

S4. If the message that the authentication is completed is not received within the preset time, it is determined that the network connection is abnormal.

As a preferred embodiment of the present invention, step 4 of the present invention specifically includes:

Step 401. If no authentication completion message is received within the preset time, a request to cancel identity authentication is sent to the underlying driver; if not received, it indicates that the current network is abnormal, such as the network is busy or congested, and the user connection times out. The underlying driver initiates a request to cancel identity authentication;

Step 402. Report the connection timeout information; report the connection timeout information to remind the user;

Step 403. After receiving the reported connection timeout information, the user interface displays the connection timeout on the user interface to inform the user whether the reason for the connection failure is the connection timeout caused by network congestion or a wrong password.

As a preferred embodiment of the present invention, the method of the present invention further includes: when there are multiple wireless access points, scanning the wireless access points one by one, and repeatedly executing steps 1-4. In real life, it is possible that the environment where the mobile terminal of the user is located may include multiple wireless access points, then when there are multiple wireless access points, scan the wireless access points one by one, and execute repeatedly until one that can connected wireless access point. If the first scanned wireless access point can be connected and surf the Internet normally, then stop scanning other wireless access points.
