Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

The terminal 120 can access the network server through a wireless local area network provided by the first wireless access point 140 or the second wireless access point 160. Assuming that the terminal 120 is currently connected to the first wireless access point 140, when the terminal 120 accesses the network server, it is detected whether the network quality between the terminal 120 and the first wireless access point 140 is worse than a first preset condition, and when the network quality between the terminal 120 and the first wireless access point 140 is worse than the first preset condition, the terminal 120 is handed over to the second wireless access point 160.

Assuming that A, B, C, D, I, J, K and L applications are installed in the terminal 120, when a user accesses a web server using an APP (Application) installed in the terminal 120, first, the APP121 sends a packet to a wireless protocol stack (wifi stack)122 in the terminal 120, the wireless protocol stack 122 forwards the received packet to a TCP/IP protocol stack 123 in a protocol layer, and the TCP/IP protocol stack 123 forwards the received packet to the first wireless access point 140 through a network card 124 in a bottom layer of the terminal 120, and accesses the web server 125 through the first wireless access point 140.

in step 201, the network quality with the currently accessed wireless access point is acquired.
In step 202, it is detected whether the network quality with the wireless access point is worse than a first preset condition.
in step 203, if the difference is less than the first predetermined condition, the access is switched to another wireless access point.
In summary, the wireless access point switching method provided in the embodiment of the present disclosure obtains the network quality between the wireless access point and the currently accessed wireless access point; detecting whether the network quality is worse than a first preset condition; if the difference is greater than the first preset condition, switching to access other wireless access points; the problem that when the terminal accesses a network server with poor performance in the related technology, the terminal is switched to other wireless access points by mistake possibly due to the self reason of the network server is solved; when the network quality between the terminal and the currently accessed wireless access point is worse than a first preset condition, the terminal is switched to be accessed to other wireless access points due to the fact that the network quality between the terminal and the wireless access points is poorer, and the effect that the terminal is switched to other wireless access points by mistake due to the self reason of a network server is avoided.
Fig. 3 is a flowchart illustrating a wireless access point handover method according to another exemplary embodiment, and the wireless access point handover method, as shown in fig. 3, applied in the terminal 120 in the implementation environment shown in fig. 1A may include the following steps.
in step 301, when accessing a web server, the network quality with the web server is obtained.
When the terminal accesses the network server, the terminal records the network quality between the terminal and the network server through a TCP/IP protocol stack in a protocol layer. When the terminal needs to acquire the network quality between the terminal and the network server, the terminal directly acquires the network quality from the TCP/IP protocol stack.
Optionally, the network quality between the terminal and the network server may be represented by at least one of a packet loss rate, a packet sending success rate, a delay duration, and a throughput.
Optionally, when the terminal accesses the corresponding network server through the application program, the network quality between the terminal and the network server is recorded in the TCP/IP protocol stack; when the terminal accesses different network servers through different application programs at the same time, the network quality between the terminal and the network server recorded in the TCP/IP protocol stack refers to the network quality between the terminal and each network server to be accessed.
in step 302, it is detected whether the network quality with the network server is worse than a second preset condition.
after the terminal acquires the network quality recorded in the TCP/IP protocol stack and between the terminal and the network server, whether the acquired network quality between the terminal and the network server is inferior to a second preset condition is detected.
This step can be implemented in several ways:
In a first implementation manner, when the network quality between the terminal and the network server is represented by a first packet loss rate, it is detected whether the first packet loss rate is greater than a first threshold.
in a second implementation manner, when the network quality between the terminal and the network server is represented by the first packet sending success rate, it is detected whether the first packet sending success rate is smaller than a second threshold.
In a third implementation manner, when the network quality between the terminal and the network server is represented by the first delay duration, it is detected whether the first delay duration is greater than a first preset duration.
in a fourth implementation, when the network quality between the terminal and the network server is represented by the first throughput, it is detected whether the first throughput is less than a third threshold.
Two detection results can be obtained by detecting whether the network quality between the terminal and the network server is worse than a second preset condition, if not worse than the second preset condition, step 303 is executed, and if worse than the second preset condition, step 304 is executed.
In step 303, if the network quality with the network server is not worse than the second predetermined condition, the access is not switched to another wireless access point.
When the network quality between the terminal and the network server is not worse than the second preset condition, it indicates that the terminal can normally access the internet at present, and no network abnormal condition occurs, so that the terminal does not need to switch to connect to other wireless access points.
in step 304, if the network quality with the network server is worse than the second preset condition, the network quality between the terminal and the currently accessed wireless access point is obtained.
When the network quality between the terminal and the network server is lower than a second preset condition, the network quality between the network card and the accessed wireless access point is poor or the performance of the accessed network server is poor, and in order to determine the reason for causing the network quality between the terminal and the network server to be lower than the second preset condition, the terminal acquires the network quality between the terminal and the currently accessed wireless access point.
optionally, after the terminal accesses the wireless access point, the terminal records the network quality between the terminal and the wireless access point through a network card in a physical layer, for example: when the distance between the terminal and the currently connected wireless access point is long, the network card of the terminal can record that the network quality between the terminal and the wireless access point is poor at the current time point; when the distance between the terminal and the wireless access point which is connected currently is short, the network card of the terminal can record that the network quality between the terminal and the wireless access point at the current time point is good.
correspondingly, the terminal acquires the network quality between the terminal and the wireless access point from the network card.
Optionally, the network quality may include: at least one of packet loss rate, packet transmission success rate, delay time and throughput.
Optionally, the wireless access point may include a router.
In step 305, it is detected whether the network quality with the wireless access point is worse than a first preset condition.
After the terminal acquires the network quality recorded in the network card and between the terminal and the wireless access point, whether the acquired network quality between the terminal and the wireless access point is worse than a first preset condition is detected.
This step can be implemented in several ways:
In a first implementation manner, when the network quality between the terminal and the wireless access point is represented by the second packet loss rate, it is detected whether the second packet loss rate is greater than a fourth threshold.
In a second implementation manner, when the network quality between the terminal and the wireless access point is represented by the second packet sending success rate, it is detected whether the second packet sending success rate is smaller than a fifth threshold.
In a third implementation manner, when the network quality between the terminal and the wireless access point is represented by the second delay duration, it is detected whether the second delay duration is greater than a second preset duration.
in a fourth implementation, when the network quality between the terminal and the wireless access point is represented by the second throughput, it is detected whether the second throughput is less than a sixth threshold.
two detection results can be obtained by detecting whether the network quality between the terminal and the wireless access point is worse than a first preset condition, and if the network quality is worse than the first preset condition, step 306 is executed; if the difference is greater than the first predetermined condition, step 307 is executed.
In step 306, if the network quality with the wireless access point is not worse than the first preset condition, the access is not switched to other wireless access points.
When the terminal detects that the network quality between the terminal and the wireless access point is not worse than the first preset condition, it indicates that the network quality between the terminal and the network server is worse not caused by the network quality between the terminal and the wireless access point, and therefore, the terminal does not switch to access to other wireless access points.
in step 307, if the network quality with the wireless access point is worse than the first predetermined condition, the access is switched to another wireless access point.
When the terminal detects that the network quality between the terminal and the wireless access point is worse than a first preset condition, the network quality between the terminal and the network server is worse, and the terminal is switched to be accessed to other wireless access points due to the fact that the network quality between the terminal and the wireless access point is worse.
In summary, the wireless access point switching method provided in the embodiment of the present disclosure obtains the network quality between the wireless access point and the currently accessed wireless access point; detecting whether the network quality is worse than a first preset condition; if the difference is greater than the first preset condition, switching to access other wireless access points; the problem that when the terminal accesses a network server with poor performance in the related technology, the terminal is switched to other wireless access points by mistake possibly due to the self reason of the network server is solved; when the network quality between the terminal and the currently accessed wireless access point is worse than a first preset condition, the terminal is switched to be accessed to other wireless access points due to the fact that the network quality between the terminal and the wireless access points is poorer, and the effect that the terminal is switched to other wireless access points by mistake due to the self reason of a network server is avoided.
In addition, when the network quality between the terminal and the network server is worse than the second preset condition and the network quality between the terminal and the wireless access point is worse than the first preset condition, the terminal is switched to be accessed to other wireless access points, so that the switching time point of the terminal switched to be accessed to other wireless access points can be more accurately determined, and the possibility that the terminal is switched to other wireless access points by mistake is reduced.
The first point to be supplemented is that, in this embodiment, an example in which one wireless access point provides one hot spot is taken as an example for illustration. When one wireless access point provides at least two hotspots, the terminal is switched to be accessed to other wireless access points, namely the terminal is switched to be accessed to other hotspots, and the terminal side does not determine whether the two hotspots are provided by the one wireless access point or not, so that the terminal is switched to be accessed to other wireless access points when the terminal side is switched to be accessed to other hotspots. In this embodiment, the number of hot spots provided by one wireless access point is not specifically limited.
A second point to be supplemented is that steps 301 to 303 in this embodiment are optional steps, and when performing a wireless access point handover, the steps 301 to 307 may be performed, or only steps 304 to 307 may be performed.
A third point to be supplemented is that, if the network quality between the terminal and the network server is worse than the second preset condition, before acquiring the network quality between the terminal and the wireless access point, the method may further include: and switching to access a preset network server.
when the network quality between the terminal and the network server is worse than the second preset condition, it is described that the network quality between the terminal and the network server is worse, and there are two reasons for the poor network quality: firstly, the performance of a network server currently accessed by a terminal is poor, so that the network quality between the terminal and the network server is poor; second, the network quality between the terminal and the wireless access point is poor, such as: when the distance between the terminal and the currently connected wireless access point is long, the network quality between the terminal and the wireless access point is poor, and finally the network quality between the terminal and the network server is poor.
In order to detect a specific reason causing poor network quality between the terminal and the network server, when the fact that the network quality between the terminal and the network server is poor than a second preset condition is detected, the terminal is switched to access the preset network server, and whether the network quality is poor due to the fact that the performance of the network server which is currently accessed by the terminal is poor is detected.
Optionally, the performance of the preset network server is good, the number of the preset network servers is not specifically limited in this embodiment, and the number of the preset network servers may be multiple or one.
after the terminal switches to access the preset network server, the network quality between the terminal and the preset network server needs to be acquired, whether the network quality is worse than a second preset condition is detected, and if the network quality between the terminal and the preset network server is worse than the second preset condition, the network quality between the terminal and a currently accessed wireless access point is acquired.
as a possible implementation manner, when there are a plurality of preset network servers, after the terminal switches to access the preset network server, before acquiring the network quality between the terminal and the currently accessed wireless access point, the method may further include the following steps:
The first step is to count the times of switching to access a preset network server within a preset time.
The terminal counts the times of switching to access the preset network server within the preset time, that is, the terminal counts the times of the network quality difference between the terminal and the network server within the preset time to be lower than the second preset condition.
And secondly, detecting whether the times reach preset times or not.
After counting the times of switching to access a preset network server within a preset time, the terminal compares the counted times with the preset times, and detects whether the counted times reach the preset times.
Third, if the number of times reaches the preset number of times, go to step 304.
and when the terminal detects that the counted times reach the preset times, acquiring the network quality between the terminal and the wireless access point.
Optionally, if the counted times detected by the terminal do not reach the preset times, the terminal does not need to switch to connect to other wireless access points.
