Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The embodiment of the application provides a WIFI connection method and device, a storage medium and a mobile terminal.

As shown in fig. 1, fig. 1 is a schematic flowchart of a WIFI connection method provided in an embodiment of the present application, where the WIFI connection method is applied to a mobile terminal, and the mobile terminal may be a device supporting WIFI connection, such as a smart phone and an iPad, and a specific flow may be as follows:

and S101, acquiring a WIFI connection request sent by a target terminal.

The mobile terminal in the embodiment of the present application may be a source terminal. The WIFI connection request is sent by the destination terminal, for example, the mobile terminal opens a WIFI hotspot, and when the destination terminal is located within a WIFI coverage range of the mobile terminal, the destination terminal can search and request to connect the WIFI hotspot, namely, the WIFI connection request is sent to the mobile terminal.

S102, randomly selecting one preset WIFI channel from N preset WIFI channels as a first target channel according to the WIFI connection request, wherein N is larger than or equal to 1.

When the mobile terminal receives the WIFI connection request, the identity of the mobile terminal in the peer-to-peer connection equipment group needs to be converted into a group administrator through a configuration algorithm, at the moment, the mobile terminal obtains the permission of selecting the WIFI channel, and one preset WIFI channel can be selected from N preset WIFI channels to serve as a first target channel. The existing channels used for wireless communication include 14 channels (channel 1 to channel 14), and since the frequency range of all WIFI signals is between 2400-. Since the channel 1, the channel 6 and the channel 11 are far apart from each other, the frequencies of the channels are not easily overlapped with each other, that is, signal interference does not easily occur between the three channels, so that the three channels become default WIFI channels, but a large number of mobile terminals in the same area all use the default WIFI channels to perform data transmission, and are easily interfered by signals with the same frequency in the data transmission process, so that the data transmission speed is delayed, and even data loss is caused.

In order to avoid the foregoing situation, preferably, the mobile terminal in this embodiment of the application does not perform WIFI connection with the destination terminal through the default WIFI channel any more, that is, the N preset WIFI channels do not include channel 1, channel 6, and channel 11, that is, the N preset WIFI channels include channel 2, channel 3, channel 4, channel 5, channel 7, channel 8, channel 9, and channel 10, so that one preset WIFI channel may be selected from the 8 preset WIFI channels as the first target channel.

In order to avoid that a large number of mobile terminals in the same area simultaneously select the same WIFI channel from N preset WIFI channels and still cause interference of the same frequency signal in the data transmission process, in the embodiment of the present application, a random algorithm is adopted, and one preset WIFI channel is selected from the N preset WIFI channels as a first target channel, where the random algorithm is an algorithm that randomly selects a next calculation step in the execution process of the random algorithm by using a probability and a statistical method.

Optionally, the step S102 specifically includes:

establishing a one-to-one corresponding relation between the N preset WIFI channels and numbers 0 to N-1;

generating a random number and calculating the remainder of dividing the random number by the N;

and taking the preset WIFI channel corresponding to the remainder as the first target channel.

Each preset WIFI channel can correspond to one number, preferably, the value of N is 8, and then 8 preset WIFI channels correspond to 8 numbers (0 to 7) one to one. For example, the channel 2 is a preset WIFI channel with an operating frequency of 2417MHz, and corresponds to the number 0; the channel 3 is a preset WIFI channel with the working frequency of 2422MHz and corresponds to the number 1; the channel 4 is a preset WIFI channel with the working frequency of 2427MHz and corresponds to the number 2; the channel 5 is a preset WIFI channel with the working frequency of 2432MHz and corresponds to the number 3; the channel 7 is a preset WIFI channel with the working frequency of 2442MHz and corresponds to the number 4; the channel 8 is a preset WIFI channel with the working frequency of 2447MHz and corresponds to the number 5; the channel 9 is a preset WIFI channel with the working frequency of 2452MHz and corresponds to the number 6; the channel 10 is a preset WIFI channel with a working frequency of 2457MHz, and corresponds to the number 7. A random number may then be generated by the linear congruential random number generator and the remainder of the random number divided by 8, which is between the numbers 0 and 7, is calculated. Therefore, according to the corresponding relation between the 8 preset WIFI channels and the 8 numbers, a first target channel corresponding to the remainder is determined. Specifically, if the remainder is 0, the corresponding channel 2 is taken as the first target channel; if the remainder is 1, taking the corresponding channel 3 as a first target channel; if the remainder is 2, taking the corresponding channel 4 as a first target channel; if the remainder is 3, taking the corresponding channel 5 as a first target channel; if the remainder is 4, taking the corresponding channel 7 as a first target channel; if the remainder is 5, taking the corresponding channel 8 as a first target channel; if the remainder is 6, taking the corresponding channel 9 as a first target channel; if the remainder is 7, the corresponding channel 10 is taken as the first target channel.

For example, the generated random number is 68, since the remainder of division of 68 by 8 is 4, and the preset WIFI channel corresponding to the number 4 is channel 7, channel 7 is selected as the first target channel.

And S103, establishing WIFI connection with the target terminal through the first target channel.

Specifically, the mobile terminal and the destination terminal may be devices supporting WIFI connection, such as a mobile phone and an iPad, as shown in fig. 2, after the mobile terminal 2001 selects the first target channel, the mobile terminal 2001 and the destination terminal 2004 may establish WIFI connection through the selected first target channel.

In one embodiment, when a WIFI connection request sent by a destination terminal is received, a preset WIFI channel is randomly selected from N preset WIFI channels directly according to the WIFI connection request to serve as a first target channel, and a WIFI connection is established with the destination terminal through the first target channel.

In another embodiment, since a certain time is consumed in the process of determining the first target channel, when receiving a WIFI connection request sent by a target terminal, the mobile terminal establishes a WIFI connection with the target terminal through a default WIFI channel, and after determining the first target channel, switches the default WIFI channel to the first target channel, so as to reestablish the WIFI connection with the target terminal through the first target channel, thereby avoiding the problem of too long time consumed by the WIFI connection, and further improving the efficiency of the WIFI connection.

Optionally, after the mobile terminal and the destination terminal establish a WIFI connection through a default WIFI channel, whether the currently used default WIFI channel is switched to the first target channel may be randomly selected through a random algorithm, so as to balance the access number of the mobile devices of each preset WIFI channel, and avoid channel waste caused by no mobile device access of the default WIFI channel.

The mobile terminal and the target terminal can perform data transmission through the first target channel after the WIFI connection is established between the mobile terminal and the target terminal through the first target channel, optionally, the mobile terminal encodes data to be transmitted and transmits the encoded data to be transmitted to the target terminal through the first target channel, and the target terminal decodes the encoded data to be transmitted after receiving the encoded data to be transmitted, so that data transmission is completed. For example, the mobile terminal encodes image data and transmits the encoded image data to the destination terminal, and the destination terminal receives the image data and decodes and displays the image data.

In one embodiment, the method further comprises:

acquiring display state data fed back by a target terminal;

detecting whether the display state data meets a preset state condition;

if yes, randomly selecting one preset WIFI channel from the N preset WIFI channels as a second target channel;

and switching the first target channel into a second target channel so as to reestablish the WIFI connection with the target terminal through the second target channel.

The display state data comprises the maximum pixel difference value of all the adjacent two pixels in the display image. The destination terminal first obtains YUV values (including Y, U, V three components, "Y" represents a gray-scale value, "U" and "V" represent chrominance, which is used to describe the color of a designated pixel) or RGB values (including R, G, B three components, which are used to represent the luminance of a pixel) of each pixel in a display image, calculates pixel difference values of all adjacent two pixels, the pixel difference values refer to the difference values of Y component, U component, V component, R component, G component, and B component, then obtains the maximum pixel difference value of all adjacent two pixels, and sends the maximum pixel difference value to the mobile terminal.

The preset state condition may be whether the maximum pixel difference value between all two adjacent pixels is greater than a preset value, specifically, the maximum pixel difference value is the maximum difference value of any same component in any two pixels.

After the mobile terminal acquires the maximum difference value of any one of the same components in all the two adjacent pixels fed back by the target terminal, judging whether the maximum difference value is larger than a preset value, if the difference value of any one of the same components in all the two adjacent pixels is smaller than or equal to the preset value, determining that the display state data does not meet the preset state condition, namely that the display data received by the target terminal is normal, namely that no interference exists in the first target channel, and therefore, the first target channel can be continuously used for communication; if the difference value of any one of the same components of the two pixels is larger than the preset value, the display state data is determined to meet the preset state condition, the display data received by the target terminal is incomplete, namely the signal interference exists in the first target channel, at the moment, the mobile terminal switches the first target channel used currently to the second target channel, and then the WIFI connection is reestablished with the target terminal through the second target channel.

For example, the preset value is 50, and the mobile terminal determines that the maximum difference value of the Y components in all two adjacent pixels fed back by the destination terminal is 55, and then determines that the difference value is greater than 50, so that it is determined that the display state data meets the preset state condition, and therefore, one preset WIFI channel is randomly selected from the N preset WIFI channels as the second target channel, and the first target channel is switched to the second target channel, so that the WIFI connection is reestablished with the destination terminal through the second target channel.

Alternatively, the destination terminal may send a channel switch request to the mobile terminal. Specifically, when the destination terminal detects that the maximum difference value of any one of the same components in all the two adjacent pixels is greater than a preset value, the destination terminal sends a channel switching request to the mobile terminal, after receiving the channel switching request, the mobile terminal randomly selects one preset WIFI channel from the N preset WIFI channels as a second target channel, switches the first target channel into the second target channel, and reestablishes the WIFI connection with the destination terminal through the second target channel.

For example, the preset value is 50, the destination terminal detects that the maximum difference value of G components in all two adjacent pixels is 60, and determines that the maximum difference value is greater than the preset value, so that a channel switching request is sent to the mobile terminal, after receiving the channel switching request, the mobile terminal randomly selects one preset WIFI channel from the N preset WIFI channels as a second target channel, and switches the first target channel into the second target channel, so as to reestablish WIFI connection with the destination terminal through the second target channel.

Specifically, a specific implementation manner of randomly selecting one preset WIFI channel from the N preset WIFI channels as the second target channel is as follows:

in one embodiment, the mobile terminal randomly selects one WIFI channel as the second target channel through a random algorithm from other preset WIFI channels except the first target channel.

In another embodiment, the mobile terminal obtains the current access number of the mobile devices in all the preset WIFI channels, and randomly selects one preset WIFI channel from the preset WIFI channels with the smallest access number as the second target channel through a random algorithm.

In another embodiment, the mobile terminal detects the current access number of the mobile devices with other preset WIFI channels except the first target channel, and selects the preset WIFI channel with the smallest access number as the second target channel, and if there are a plurality of preset WIFI channels with the smallest access number, selects one of the preset WIFI channels with the smallest access number as the second target channel through a random algorithm.

As shown in fig. 3, fig. 3 is another schematic flow diagram of the WIFI connection method provided in the embodiment of the present application, and the specific flow may be as follows:

s201, establishing one-to-one corresponding relation between N preset WIFI channels and numbers 0 to N-1.

For example, the value of N is 8, and channel 2 is a preset WIFI channel with an operating frequency of 2417MHz, corresponding to the number 0; the channel 3 is a preset WIFI channel with the working frequency of 2422MHz and corresponds to the number 1; the channel 4 is a preset WIFI channel with the working frequency of 2427MHz and corresponds to the number 2; the channel 5 is a preset WIFI channel with the working frequency of 2432MHz and corresponds to the number 3; the channel 7 is a preset WIFI channel with the working frequency of 2442MHz and corresponds to the number 4; the channel 8 is a preset WIFI channel with the working frequency of 2447MHz and corresponds to the number 5; the channel 9 is a preset WIFI channel with the working frequency of 2452MHz and corresponds to the number 6; the channel 10 is a preset WIFI channel with a working frequency of 2457MHz, and corresponds to the number 7.

S202, when a WIFI connection request sent by a target terminal is received, a random number is generated, and the remainder of dividing the random number by N is calculated.

For example, as shown in fig. 2, a user clicks a "hotspot state" control 2003 on a mobile network sharing interface 2002 in a mobile terminal 2001 to open a WIFI hotspot, at this time, the mobile terminal 2001 serves as an access point of a WIFI network, and covers a WIFI hotspot signal within an effective range, a destination terminal 2004 within a range covered with the WIFI hotspot signal clicks a "WIFI" control 2006 on a WIFI interface 2005 to search for a nearby available WIFI network, after detecting the WIFI hotspot signal, a network selection control 2007 for accessing to the WIFI hotspot network of the mobile terminal 2001 is selected from an available network list in the WIFI interface 2005, and a WIFI network connection password is input, and when the password verification is passed, a WIFI connection request is sent to the mobile terminal 2001. After receiving the WIFI connection request, the mobile terminal generates a random number 325, and calculates a remainder obtained by dividing 325 by 8 to be 5.

And S203, taking the preset WIFI channel corresponding to the remainder as a first target channel.

For example, since the remainder obtained by dividing the random number 325 by 8 is 5, and the preset WIFI channel corresponding to the number 5 is the channel 8, the channel 8 is taken as the first target channel.

And S204, establishing WIFI connection with the target terminal through the first target channel.

For example, when it is determined that the channel 8 is the first target channel, the mobile terminal 2001 establishes a WIFI connection with the destination terminal 2004 through the channel 8, displays the number of connected devices on the mobile network sharing interface 2002 in the mobile terminal 2001, and displays the WIFI network identifier 2008 on the screen of the destination terminal 2004.

Optionally, when a WIFI connection request sent by the destination terminal is received, firstly, a WIFI connection is established with the destination terminal through a default WIFI channel, and then the default WIFI channel is switched to a first target channel, so that the WIFI connection is reestablished with the destination terminal through the first target channel.

For example, the mobile terminal 2001 sets a WIFI channel thereof as a channel 6 when leaving the factory, and after the mobile terminal 2001 receives a WIFI connection request sent by the destination terminal 2004, firstly, a WIFI connection is established with the destination terminal 2004 through the channel 6 by default, then, a channel 8 is selected as a first target channel through a random algorithm, and then, the channel 6 is switched to the channel 8, so that the WIFI connection is established with the destination terminal 2004 through the channel 8.

And S205, obtaining display state data fed back by the destination terminal through the first target channel.

For example, the mobile terminal 2001 encodes a picture data and transmits the picture data to the destination terminal 2004 through the channel 8, and the destination terminal 2004 decodes the picture data after receiving the picture data and feeds back the maximum difference value of any one same component of any two adjacent pixels in the picture data to the mobile terminal 2001.

S206, detecting whether the display state data meets the preset state condition, if so, executing the step S207, otherwise, returning to the step S205.

For example, if the preset condition is that the maximum difference value of any one same component of any two adjacent pixels in the picture data is greater than 50, the mobile terminal 2001 detects that the maximum difference value of V components of any two adjacent pixels in the picture data is 60, that is, it indicates that the picture data satisfies the preset condition, and step S207 is executed; if the maximum difference value of any identical component of any two adjacent pixels in the picture data is 35, that is, the picture data does not satisfy the preset state, the process returns to step S205.

S207, the device access number of each preset WIFI channel in the N preset WIFI channels is obtained, one preset WIFI channel is randomly selected from the preset WIFI channels with the minimum device access number to serve as a second target channel, the first target channel is switched to the second target channel, and WIFI connection is reestablished with the target terminal through the second target channel.

For example, if it is detected that the current mobile device in the 8 preset WIFI channels has the least number of access channels 4 and 7, channel 4 is selected as the second target channel through a random algorithm, channel 8 is switched to channel 4, and then the WIFI connection is reestablished with the destination terminal 2004 through channel 4.

Therefore, the WIFI connection method is applied to the mobile terminal, the WIFI connection request sent by the target terminal is obtained, one preset WIFI channel is randomly selected from N preset WIFI channels according to the WIFI connection request to serve as the first target channel, N is larger than or equal to 1, then the WIFI connection is established with the target terminal through the first target channel, a large number of mobile devices in the same area are prevented from simultaneously using the same channel for communication, interference in the data transmission process is reduced, the transmission efficiency of display data is improved, and the picture display effect is further improved.

According to the method described in the foregoing embodiment, the present embodiment will be further described from the perspective of a WIFI connection device, which may be specifically implemented as an independent entity, or integrated in a mobile terminal, where the mobile terminal may be a smart phone, an iPad, or other devices.
