Wireless local area network roaming method and communications apparatus
A wireless local area network roaming method and a communications apparatus are provided, to improve a roaming effect of a terminal device in a wireless local area network. In the method, a control device selects, in place of a terminal device, an optimal roaming access point of the terminal device, to reduce a time consumed for determining the optimal roaming AP. After the optimal roaming access point of the terminal device is determined, an associated access point instructs the terminal device to attempt to roam to the optimal roaming access point. Because duration required for searching for the optimal roaming AP is reduced, a probability of data loss of the terminal device in a roaming process can be reduced, and a roaming effect of the terminal device in the wireless local area network is improved.
