Description

Method and system for STA to select and switch AP under multi-AP environment

Technical Field

The invention belongs to the technical field of WIFI connection, and particularly relates to a method and a system for STA to select and switch APs in a multi-AP environment.

Background

WiFi network speed is an important indicator for measuring WiFi performance, and is an object of important improvement since the invention of wireless networks.

Firstly, due to technical iteration, the WiFi speeds of different protocol versions are different, and the speeds under the same protocol version are also different. After the STAs attach to the AP, they negotiate a rate with each other, which is then used for communication. During a connection, the STA will not actively switch APs unless the signal strength is less than a threshold.

Secondly, even if there is a higher transmission rate between the STA and the AP, the STA cannot obtain a higher internet rate due to the limitation of the internet speed at the upper end of the AP.

The method and the system for STA to select and switch the AP under the multi-AP environment are provided aiming at the problems, the use gap of a user is reasonably utilized, after the STA is stopped, the previously authenticated APs are tried one by one, the network speed is tested, and then the connection with the highest network speed in the authenticated list is switched, so that the user can enjoy the connection with the fastest speed in the current wireless network environment when using the STA next time.

Disclosure of Invention

The invention aims to provide a method and a system for selecting and switching an AP by an STA in a multi-AP environment in order to enable a user to obtain the highest internet surfing rate when using the STA in the multi-AP environment.

In order to achieve the above object, the present invention has the following design scheme:

the system comprises a screen-extinguishing triggering module, an AP selecting module, an AP switching module and a network speed testing module, wherein the screen-extinguishing triggering module is used for triggering and executing the method, namely an entry of the method, the AP selecting module is used for selecting an AP which does not pass the network speed test from an authenticated AP list, if all the APs pass the network speed test, the program is ended, the AP switching module is used for disconnecting the existing connection to connect a designated AP, and the network speed testing module is used for testing the current network speed.

A method for STA to select and switch AP under multi-AP environment comprises the following specific steps:

the STA screen-off event triggers a screen-off triggering module;

and (II) selecting an AP module, detecting whether an untested AP exists, if so, selecting an untested AP, executing the step (III), and if not, clearing all test marks in the list and exiting.

Switching an AP module to connect the selected AP;

the network speed testing module is used for testing the network speed of the current connection, judging whether the network speed of the current connection is greater than the network speed of the original connection, if so, staying in the current connection, and if not, switching back to the original connection; and (3) executing the step (II).

Compared with the prior art, the invention has the beneficial effects that:

1. the invention automatically carries out AP selection and switching after the STA is on screen, and does not increase the operation burden of the user.

2. The method can automatically help the STA to select and switch to the connection with the fastest network speed, so that the STA obtains the fastest network speed in the current network environment, and can exert the network performance of the AP to a greater extent.

Detailed Description

The technical scheme of the patent is further described in detail below with reference to the specific embodiments.

Referring to fig. 1, a system for STA selecting and switching APs in a multi-AP environment includes a screen-off triggering module, an AP selecting module, an AP switching module and a network speed testing module, where the screen-off triggering module is used to trigger execution of the method, i.e. an entry of the method, the AP selecting module is used to select an AP that does not pass the network speed test from an authenticated AP list, if all APs have passed the network speed test, the program ends, the AP switching module is used to disconnect the existing connection to connect to a designated AP, and the network speed testing module is used to test the current network speed.

As shown in fig. 2, a method for selecting and switching APs by an STA in a multi-AP environment includes the following specific procedures: the screen-extinguishing triggering module is triggered when the STA is in screen, the trigger is sent to the AP selection module, the AP selection module can select one AP which is not subjected to the network speed test from an AP list (authenticated, namely, the AP which is connected before and cannot be connected without the authentication, the password is not known) to be connected, and if all the APs in the list are subjected to the test, all the test marks are cleared and the AP is withdrawn.

And when the network speed is found to be low when the network speed is switched from the original connection to other connections, switching back to the original connection, and continuing to attempt to connect the next connection from the original connection. Therefore, when switching to a connection without a network or with an excessively low network speed, the data communication method can ensure that the data communication of the STA is normal.

The network speed testing tool uses a speedtest_cli (an open source network speed testing tool, servers of which are distributed around the world, can automatically select a server closest to the current network for testing, and can manually designate the server for uploading and downloading testing), and the error caused by single testing is reduced by performing three-time testing and averaging on each connection.

According to the invention, the AP selection and switching are automatically carried out after the STA is on the screen, so that the operation burden of a user is not increased; can automatically help the STA to select and switch to the connection with the fastest network speed, so that the STA obtains the fastest network speed in the current network environment

The above described embodiments are only preferred examples of the invention and are not exhaustive of the possible implementations of the invention. Any obvious modifications thereof, which would be apparent to those skilled in the art without departing from the principles and spirit of the present invention, should be considered to be included within the scope of the appended claims.
