Abstract
Embodiments of the present application disclose a roaming method for a wireless terminal. The method includes: detecting that first comprehensive signal quality of a first wireless terminal is lower than a first specified threshold, reducing a transmit power by a first specified value, wherein the specified packets are null packets, and sending specified packets to the first wireless terminal, so that the first wireless terminal broadcasts a probe request; sending, to neighboring APs, a scan request carrying a first identifier and a first channel accessed by the first wireless terminal, so that the neighboring APs return a scan response carrying the first identifier and third comprehensive signal quality; selecting a switch-to AP from the neighboring APs based on the first comprehensive signal quality and third comprehensive signal quality; and sending a transmit-power increasing notification carrying the first identifier and a second specified value to the switch-to AP.
