The terms "first", "second" and the like in the specification and claims of the present invention and the above drawings are used to distinguish different objects, and are not intended to describe a specific order. Furthermore, the terms "comprises" and "comprising" and "comprising" are intended to cover a non-exclusive inclusion. For example, a process, method, system, product, or device that comprises a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units not listed, or alternatively Other steps or units inherent to these processes, methods or devices.

The embodiment of the invention provides a method for connecting a hidden AP and a terminal device, which can switch different character encoding modes to scan the hidden AP, avoiding the situation that the hidden AP is not found due to the inconsistent character encoding manner, and improving the success rate of the scanning connection. The details are described below separately.

Please refer to FIG. 1. FIG. 1 is a schematic flowchart diagram of a method for connecting a hidden AP according to an embodiment of the present invention. The method shown in FIG. 1 may include the following steps:

101. Obtain a service set identifier SSID of a hidden AP that the user wants to connect to.

In the embodiment of the present invention, the terminal device acquires the SSID of the hidden AP that the user wants to connect.

The foregoing terminal device may be a smart phone, a tablet computer, a personal digital assistant (PDA), a point of sales (POS), etc., and is not repeatedly described in the embodiment of the present invention.

As an optional implementation manner, the user clicks the button of “Add Network” displayed on the display interface of the terminal device, and the terminal device displays a dialog box to enable the user to input the SSID and password of the hidden AP that is to be connected, and the terminal device receives the button. After the above SSID and password, the default character encoding is used for the SSID. The way to encode and start scanning the hidden AP.

As an optional implementation manner, the user scans the two-dimensional code that provides the SSID and the password of the hidden AP by using the terminal device, and the terminal device parses the information included in the scanned two-dimensional code, and then from the information included in the two-dimensional code. Get the SSID of the hidden AP that the user wants to connect to.

As another optional implementation manner, the user may use a terminal device to capture a picture including the SSID of the hidden AP to obtain a target image, and perform text recognition on the target image to obtain an SSID of the hidden AP. Since the SSID is often set longer, the user's manual input is time-consuming and error-prone; in this way, the user can conveniently obtain the SSID name without manual input, thereby improving the convenience of searching for hidden APs.

As another optional implementation manner, the user may perform recording by using a microphone to obtain target voice information, and perform voice recognition on the target voice information to obtain an SSID of the hidden AP. When the user informs the user to hide the SSID of the AP, the user needs to manually input the heard SSID to the terminal device to initiate a search for the hidden AP; and by this embodiment, the user can conveniently obtain the SSID name without manual input. Improves the convenience of searching for hidden APs.

102. Encode the SSID by using a first character encoding manner.

Usually, the hidden AP is connected. You need to scan the specified SSID to find the AP. If you scan the AP with the specified SSID, you will try to connect. Due to the difference in the SSID encoding mode, if the SSID included in the scanning request broadcast by the terminal device is different from the character encoding mode used by the hidden AP, the AP will still fail to match the SSID after receiving the scanning request, and the terminal device cannot find the AP.

103. Broadcast a first scan request including the encoded SSID to find the hidden AP.

In the embodiment of the present invention, the terminal device first encodes the acquired SSID by using a default character encoding manner, and generates a first scan request including the encoded SSID. The foregoing character encoding mode may be GBK, Unicode, ASCII, UTF-8, etc., and the specific manner is not limited in the embodiment of the present invention.

After the first scan request is broadcasted, the time after the first scan request is broadcasted; if the time after the first scan request is broadcast has exceeded a preset threshold, the terminal device does not receive the first response of the hidden AP. The message confirms that the above hidden AP is not found.

104. If the hidden AP is not found, re-encoding the SSID by using a second character encoding manner, and broadcasting a second scan request including the re-encoded SSID.

In the embodiment of the present invention, if the first scanning request including the encoded SSID cannot be used to find the hidden AP, it is presumed that the SSID encoded by the first character encoding method does not match the SSID encoding mode of the hidden AP, and may be replaced. The manner in which the scan request is resent after the character encoding mode of the SSID continues to try to find the above hidden AP.

As an optional implementation, if the hidden AP is searched, the Received Signal Strength Indication (RSSI) of the hidden AP may be obtained. If the RSSI of the hidden AP is greater than a preset threshold, the hidden AP is sent to the hidden AP. Access request. If the RSSI of the AP is less than the preset threshold, the prompt message is output to prompt the user that the AP signal quality is poor. It is recommended to select another AP for access. In this way, avoiding APs with poor access signals causes problems such as dropped calls and frequent roaming.

It can be seen that, by using the method described in FIG. 1, different character encoding modes can be switched to scan the hidden AP, and the hidden AP cannot be found due to the inconsistent character encoding manner, thereby improving the success rate of the scanning connection.

Please refer to FIG. 2. FIG. 2 is a schematic flowchart diagram of another method for connecting a hidden AP according to an embodiment of the present invention. As shown in FIG. 2, the method may include the following steps:

201. Obtain a service set identifier SSID of a hidden AP that the user wants to connect.

202. Encode the SSID by using a first character encoding manner.

203. Broadcast a first scan request including the encoded SSID to find the hidden AP.

204. If the hidden AP is found, determine whether the hidden AP can be successfully accessed.

In the embodiment of the present invention, if the character encoding mode of the SSID in the first scan request sent by the terminal device is consistent with the manner in which the hidden AP performs character encoding on the SSID, the hidden AP returns a first response message to the terminal device to notify the terminal device. Scan to the AP; then the hidden AP will verify the first Whether the encryption mode in the scan request is consistent with the setting of the device, and then verifying that the password of the SSID provided in the first scan request is correct. After the verification is successful, the hidden AP authorizes the terminal device to access the hidden AP, and The terminal device returns a response message to notify the access success.

As an optional implementation manner, the terminal device receives the second response message returned by the hidden AP, and determines whether the hidden AP can be successfully accessed by using the error code included in the second response message.

According to the verification process performed by the hidden AP, if the encryption mode in the first scan request is different from the setting of the hidden AP, or the password of the SSID provided in the first scan request is incorrect, the connection may fail. Therefore, the encryption method in the scan request or the character encoding mode of the password corresponding to the SSID can be modified, and the access request is sent to the AP again.

205. If the hidden AP is not successfully accessed, modify the encryption manner in the first scan request to obtain a third scan request and broadcast the third scan request.

In the embodiment of the present invention, when the AP is set up, the administrator of the AP sets the encryption mode when the AP sends and receives data through the AP. The encryption mode includes the pre-shared key wireless network security access WPA-PSK and the wireless network security connection. Into WPA and wired equivalent confidential WEP, etc. When the terminal device requests access to the hidden AP, the scanning request or the access request needs to include the same encryption mode as the AP to successfully access the AP.

Therefore, if the terminal device determines that the hidden AP cannot be successfully accessed by analyzing the error code, the encryption method in the scan request is modified to generate a third scan request, and the third scan request is broadcasted to access the AP.

In addition, in order to cope with the unsuccessful access caused by the character encoding method of the password, the following method may be adopted: if the hidden AP cannot be successfully accessed, the third character encoding method is used to perform the password corresponding to the SSID. Encoding again, and sending an access request containing the re-encoded password described above to the hidden AP.

Referring to FIG. 2A, FIG. 2A is a schematic diagram of interaction of a hidden AP according to an embodiment of the present invention. The terminal device obtains the SSID of the hidden AP, and then encodes the SSID by using the first character encoding manner, and then sends the first scan request including the encoded SSID to the hidden AP; the hidden AP parses the first scan request, and obtains the The encoded SSID is matched with the SSID of the device; if the SSID matches successfully, the hidden AP sends a first response message to the terminal device to notify the terminal device to find the hidden AP; and the hidden AP further acquires the first scan request. Encryption mode and compare with the encryption mode of the device; if the encryption method in the first scan request is in the device If the encryption mode does not match, the hidden AP sends a second response message including the error code A to the terminal device to notify the terminal device that the access fails; the terminal device parses the received second response message, and determines the encryption mode error by using the error code A, thereby After the encryption mode is modified, the first access request is sent to the hidden AP; the hidden AP obtains the password corresponding to the SSID in the access request, and matches the password corresponding to the SSID stored in the device; if the password corresponding to the SSID in the access request If the password stored by the device does not match, the hidden AP sends a third response message including the error code B to the terminal device to notify the terminal device that the access fails; the terminal device parses the received third response message, and determines the password by using the error code B. The character encoding manners are inconsistent, and the third password encoding method is used to re-encode the password corresponding to the SSID, and then the second access request is sent to the hidden AP.

It can be seen that, by using the method described in FIG. 2, different character encoding modes can be switched to scan the hidden AP, and the hidden AP cannot be found due to the inconsistent character encoding manner, thereby improving the success rate of the scanning connection.
