Abstract
The invention discloses a method for realizing household WIFI roaming, which comprises an AP1 serving as a main AP and an extended AP: AP2, AP3, and AP 4; firstly, the STA sends a request to the AP2 to request to obtain the current neighbor list, and then the AP2 replies the neighbor list under the current environment to the STA; then the STA acquires the connection parameters of each AP; then the AP2, the AP3 and the AP4 send WIFI signal parameters of the same AP to the master AP; then, after acquiring the optimal roaming target AP of the STA according to a specific method, the main AP sends the target AP to the AP2 which is connected with the STA; then the AP2 informs the STA to roam to the AP3 through the 802.11v protocol; after receiving the message from the AP2, the STA actively roams to the AP3, and completes roaming. The WIFI roaming mode fully utilizes the interaction about neighbor info in a new 802.11k protocol, and increases the information interaction between the STA and each AP to be roamed; through the BSS Transition function in the 802.11v protocol, the STA is informed to roam the target AP, so that WIFI roaming is more accurate, and the problems of short interruption of data, poor WIFI signals after roaming and the like in the conventional WIFI roaming are avoided.

Technical Field
The invention belongs to the field of household WIFI, and relates to a WIFI roaming implementation method, in particular to a household WIFI roaming implementation method.
Background
At present, household WIFI is used more and more, WIFI network coverage is more and more popularized through the mode of AP + WIFI expander, but most of modes of realizing roaming in the WIFI network are that the STA is kicked off when the access point detects that parameters such as RSSI (received signal strength indicator) connected with the STA and the access point are reduced, the STA is enabled to actively search for the next access point, WIFI roaming is completed, the problem that the STA cannot roam to the best access point can be caused, and a short network connection interruption phenomenon can occur in the roaming process. To solve the above-mentioned drawbacks, a solution is now provided.
Disclosure of Invention
