The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

The terms "first", "second", "third" and "fourth" in the description and claims of the present invention and the drawings are used to distinguish different objects, rather than to describe a specific order . Furthermore, the terms "include" and "have", as well as any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but optionally also includes unlisted steps or units, or optionally further includes For other steps or units inherent in these processes, methods, products or apparatuses.

Reference herein to an "embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present invention. The presentation of this phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are independent or alternative embodiments mutually exclusive of other embodiments. It is understood explicitly and implicitly by those skilled in the art that the embodiments described herein can be combined with other embodiments.

The mobile terminal described in the embodiment of the present invention may include a smart phone (such as an Android phone, an iOS phone, a Windows Phone, etc.), a tablet computer, a palmtop computer, a notebook computer, a mobile Internet device (MID, MobileInternet Devices) or a wearable device, etc. The above is only an example, not an exhaustive list, including but not limited to the above mobile terminal.

It should be noted that the embodiment of the present invention is mainly applicable to two or more access points with the same SSID and encryption method but different passwords in the surrounding environment. After Wi-Fi scanning, if there are two access points with the same SSID and encryption method but different passwords, the mobile terminal will identify them as one access point. If you enter one of the passwords to connect, there may be a Matches the problem of not being able to connect. For example, access point A and access point B, where the SSID of access point A is: cathay000, the encryption method is: WAP_PSK, the password: 12345678, the SSID of access point B is: cathay000, the encryption method is: WAP_PSK, The password is: 88888888. If the mobile terminal only uses the SSID to search for access point A and access point B, only one of the access point A or access point B will be found. If the mobile terminal searches for access point A, it may follow the The password of access point B is used to connect to access point A, so the connection to access point A fails. Similarly, if the mobile terminal searches for access point B, it may use the password of access point A to connect to the access point. Point B, thus, causes the connection to access point B to fail.

It should be noted that the hash table in this embodiment of the present invention includes multiple records, and each record includes a BSSID and a password corresponding to the BSSID. For example, after a mobile terminal successfully connects to an AP, it can record the SSID, encryption method, BSSID and password of the AP, and store the BSSID and password as a key-value pair in a hash table (HASH). Contains multiple records, and the format of each record can be as follows: Take AP1 as an example, its BSSID: BSSID1, its password: password 1, which can be recorded as (BSSID1, password 1). The following embodiments of the present invention will only be described in the case where there are two access points with the same SSID and encryption method in the environment where the mobile terminal is located. In practical applications, the environment where the mobile terminal is located may contain more than two access points with the same encryption method The implementation principle of the access point is similar to that of the embodiment of the present invention.

Please refer to FIG. 1 , which is a schematic flowchart of a first embodiment of a wireless fidelity Wi-Fi connection method provided by an embodiment of the present invention. The wireless fidelity Wi-Fi connection method described in this embodiment includes the following steps:

101. When the distance between the mobile terminal and the first access point reaches the roaming condition, acquire the target BSSID of the second access point, wherein the SSID and encryption method of the first access point and the second access point are the same.

Wherein, the SSID and encryption method of the first access point and the second access point are the same, but the passwords of the first access point and the second access point are different. The coverage of the first access point and the coverage of the second access point have a certain overlapping area. Of course, the coverage of the first access point may not overlap with the coverage of the second access point. After the mobile terminal is connected to the first access point, if it reaches a certain distance away from the first access point, the signal strength of the first access point detected by it will become weaker and weaker, thus, roaming may be triggered. conditions, so that access to other access points. When the mobile terminal roams within the coverage of the second access point, the target BSSID of the second access point can be acquired. In the acquisition of the target BSSID of the second access point, the mobile terminal may perform Wi-Fi scanning, thereby obtaining the BSSID of the second access point. Of course, the target BSSID of the second access point can be pre-stored in the mobile terminal, so that the target BSSID can be read directly.

102. Detect whether there is a first password corresponding to the target BSSID in a pre-stored hash table, the hash table includes K records, each record includes a BSSID and a password corresponding to the BSSID, and the K is a positive integer.

Wherein, it can be seen from the above that there are multiple records stored in the pre-stored hash table, assuming K records, wherein K is a positive integer, and each record includes a BSSID and a password corresponding to the BSSID. Therefore, after obtaining the target BSSID of the second access point, the hash table can be searched according to the target BSSID, and if the target BSSID exists, the corresponding password can be found. If the password corresponding to the target BSSID does not exist in the hash table, the user may be prompted to input the password corresponding to the target BSSID, and log in to the second access point according to the password.

103. When a first password corresponding to the target BSSID exists in the hash table, access the second access point according to the first password.

Wherein, when there is a first password corresponding to the target BSSID in the hash table, the second access point can be accessed according to the first password. Specifically, Wi-Fi scanning can be performed according to the target BSSID. After the second access point, the second access point can be accessed according to the password.

For example, during the Wi-Fi scanning process of the mobile terminal, two access points with the same SSID and encryption method but different passwords may appear, for example: AP1 and AP2. In the specific implementation, if you manually connect to an AP, you can record the SSID, encryption method, BSSID, and password of the AP, and store its BSSID and password as a key-value pair in the hash table. If you connect to AP1, record it as (BSSID1, password 1), when the mobile terminal disconnects AP1 and re-connects to Wi-Fi, it can select a password from the hash table according to the selected BSSID, if a password is selected, then connect according to the password, if not If the password is selected, the user will be prompted to re-enter a new password to connect. To connect to AP2, you can re-enter the AP2 password to connect. After the connection is successful, you can store the BSSID and password of AP2 in the hash table, such as (BSSID2, password 2). After disconnecting from AP2 and reconnecting, you can Select a password to connect AP1 and AP2. For example, if there is an intersecting area between AP1 and AP2, in this area, if the connection to AP1 fails, you can connect to AP2.

For another example, there are two access points with the same SSID and encryption method but different passwords in the surrounding environment of the mobile terminal, such as AP1 and AP2. In the specific implementation, if you manually connect to an AP, you can record the SSID, encryption method, BSSID, and password of the AP, and store its BSSID and password as a key-value pair in the hash table. If you connect to AP1, record it as (BSSID1, password 1), when the mobile terminal is far away from AP1 and meets the roaming conditions, you can select AP2, first read the corresponding password 2 from the hash table according to the BSSID2 of AP2, if it exists, update the password to perform roaming switching, if not If it exists, the user will be prompted to enter a new password. After re-entering the password to connect, store the BSSID and password of AP2 in the hash table. Roaming switching, you can achieve intelligent selection of passwords for roaming.

It can be seen that, through the embodiment of the present invention, when the distance between the mobile terminal and the first access point reaches the roaming condition, the target BSSID of the second access point is obtained, wherein, the first access point and the second access point SSID and encryption method are the same, detect whether there is the first password corresponding to the target BSSID in the pre-stored hash table, the hash table contains K records, each record contains a BSSID and the password corresponding to the BSSID, K is a positive integer, and when the first password corresponding to the target BSSID exists in the hash table, the second access point is accessed according to the first password. Therefore, fast access to the network can be realized when there are multiple access points with the same SSID and encryption method but different passwords in the environment.

202. Detect whether there is a first password corresponding to the target BSSID in a pre-stored hash table, the hash table includes K records, each record includes a BSSID and a password corresponding to the BSSID, and the K is a positive integer.

203. When a first password corresponding to the target BSSID exists in the hash table, access the second access point according to the first password.

Wherein, the specific description of the above steps 201 to 203 can refer to the corresponding steps 101 to 103 of the Wi-Fi connection method described in FIG. 1 .

204. Acquire an input second password when the first password corresponding to the target BSSID does not exist in the hash table.

Wherein, if the first password corresponding to the target BSSID does not exist in the hash table, it is possible that the mobile terminal connects to the second access point for the first time, and therefore, the user may input the second password of the second access point by himself.

205. Access the second access point according to the second password.

Wherein, the mobile terminal may verify the second password, and then, if the verification of the second password is successful, access the second access point.

206. When the second password successfully accesses the second access point, save the target BSSID and the second password as a record in the hash table.

Wherein, when the second password successfully accesses the second access point, the target BSSID and the second password may be saved as a record in the hash table, for example, (target BSSID, second password).

It can be seen that, through the embodiment of the present invention, when the distance between the mobile terminal and the first access point reaches the roaming condition, the target BSSID of the second access point is obtained, wherein, the first access point and the second access point SSID and encryption method are the same, detect whether there is the first password corresponding to the target BSSID in the pre-stored hash table, the hash table contains K records, each record contains a BSSID and the password corresponding to the BSSID, K is a positive integer. When the first password corresponding to the target BSSID exists in the hash table, the second access point is accessed according to the first password. When the first password corresponding to the target BSSID does not exist in the hash table, the The user's second password, and access to the second access point according to the second password.

33) Judging whether the distance value is less than a preset threshold, and confirming that the mobile terminal has roamed to the coverage of the second access point when the distance value is less than the preset threshold.

Wherein, the mobile terminal may determine the current location of the mobile terminal through a Global Positioning System (Global Positioning System, GPS), or the mobile terminal may determine the current location of the mobile terminal through a Wi-Fi positioning technology. The current location of the above-mentioned mobile terminal can be represented by latitude and longitude, for example, the current location can be represented as 113°46' east longitude and 22°27' north latitude. Of course, if the Wi-Fi positioning technology is used to determine the current location of the mobile terminal, then the location of an AP scanned by the current Wi-Fi is used as the location of the mobile terminal. If the location of the AP is marked on the indoor map, it can be used as is a point (a point representing the position of the mobile terminal). Wherein, if the Wi-Fi positioning technology is used for positioning, the position of the second access point may be a known quantity, which may be marked on the indoor map. Therefore, the distance value between the current location and the location of the second access point can be determined, whether the distance value is less than a preset threshold can be determined, and when the distance value is less than the preset threshold, it is confirmed that the mobile terminal roams to the second access point If the distance is greater than or equal to the preset threshold, it is confirmed that the mobile terminal has not roamed into the coverage of the second access point.
