It should be noted that, in this embodiment, a unified roaming mechanism is set through preset roaming rules, and the preset roaming rules can be flexibly changed through configuration, for example, by adding conditions or parameters for roaming judgment, updating roaming mechanism, in which, due to the setting of unified preset roaming rules, different terminal products will have a consistent roaming effect when networking. , to improve the performance of wireless mesh networking and enhance the experience of wireless mesh network users.

Specifically, in this embodiment, the wireless network roaming method is applied to a wireless network roaming system. The wireless network roaming system belongs to wireless network roaming equipment, and one or more roaming critical areas are preset in the wireless network roaming system. , the roaming critical area refers to the critical area of the coverage of two APs. For the wireless network roaming system, the parameter information of each terminal in each preset roaming critical area is collected in real time. Therefore, for the wireless network roaming system In other words, each time the first wireless parameter information reported by the first terminal is detected, the second wireless parameter information reported by other second terminals in the preset roaming critical area can be acquired in real time. When there is terminal a in the roaming critical area of the network roaming system, it will receive the first wireless parameter information reported by terminal a. When receiving the first wireless parameter information reported by terminal a, the roaming critical area A will obtain the The second wireless parameter information reported by other second terminals in the roaming critical area is preset.

That is, the first terminal refers to a terminal that has just entered the roaming critical area, and the first wireless parameter information includes front-end parameter information and back-end parameter information of the first terminal. Specifically, the first wireless parameter information includes the traffic of the first terminal. Usage status, WIFI usage status, and wireless received signal strength, etc. After acquiring the first radio parameter information, acquire the second radio parameter information reported by other second terminals in the preset roaming critical area, where the second terminal refers to the first terminal already in the preset roaming critical area For other terminals other than the terminal, the second wireless parameter information of the second terminal includes information such as the number of the second terminals, the WIFI usage status of each second terminal, and the current traffic usage status of each second terminal.

The throughput may refer to the current network rate of M/S or KB/S.

Step A2: Acquire multiple second master throughputs and multiple second slave throughputs corresponding to the master access point and the slave access point respectively in the preset roaming critical area under different wireless received signal strengths obtaining a second relationship diagram of the influence of the wireless received signal strength in the preset roaming critical area on the wireless network performance according to the multiple second master throughputs and the multiple second slave throughputs;

Step A5: Determine the preset roaming rule according to the first relationship diagram, the second relationship diagram, the third relationship diagram, and the fourth relationship diagram.

The preset roaming rule is determined comprehensively according to the first relational graph, the second relational graph, the third relational graph, and the association relationship between the throughput of the AP and each parameter in the fourth relational graph.

As shown in FIG. 4 , after the step of determining whether the first terminal is wireless roaming according to the interaction parameter information, the first wireless parameter information and the preset roaming rule, the step includes:

Step S40, if it is determined that the first terminal points to the roaming result, collect the current traffic usage rate of the first terminal;

Step S50, if the current traffic usage rate of the first terminal is greater than a preset value of the traffic rate, suspend the wireless network roaming operation for the first terminal.

In this embodiment, a fault tolerance function is also implemented, that is, specifically, if it is determined that the first terminal points to the roaming result, the current traffic usage rate of the first terminal is collected, and the current traffic usage rate of the first terminal is collected. The purpose is to determine whether the terminal currently needs to roam. If the current traffic usage rate of the first terminal is greater than the preset value of the traffic rate, the terminal may be using traffic to download applications and other operations at this time, and wireless roaming at this time will cause the download and other operations to be suspended. Therefore, in order to avoid The download is suspended, and the wireless network roaming operation is suspended for the first terminal, so as to avoid disconnection and improve user experience.

The roaming determination factors are generally pre-set and tested. Therefore, the probability that the performance of the first terminal after roaming is higher than the performance before roaming increases, and the probability of achieving an ideal roaming effect also increases. Because the determination conditions are too single, it is a technical problem that the performance of the terminal after roaming is lower than the performance before roaming.

Step D2: Determine the preset roaming rule according to the determination weight of each roaming determination factor, the determination turning point of each roaming determination factor, and the access point weight.

The preset roaming rule is determined according to the determination weight of each roaming determination factor, the determination turning point of each roaming determination factor, and the access point weight. Since the preset roaming rule is accurately generated, the first roaming rule can be accurately The terminal determines whether to roam or not.
