Abstract:
A wireless roaming method and system. The method is applied to an AP, and comprises: obtaining terminal information of wireless terminals currently accessing the AP; according to an RSSI value and an idle duration in the terminal information of each wireless terminal, determining, from the wireless terminals, a roaming terminal which is currently in an active state; for each roaming terminal, determining a wireless roaming protocol supported by the roaming terminal, wherein the wireless roaming protocol comprises a 802.11k-based roaming protocol, a 802.11r-based roaming protocol, and a 802.11v-based roaming protocol; and according to the wireless roaming protocol supported by the roaming terminal, executing a roaming operation for the roaming terminal. Embodiments of the present invention avoid, to the greatest extent, the problem of roaming latency, packet loss or disconnection caused by selecting an inappropriate roaming protocol to achieve the roaming of a roaming terminal, so that the roaming experience of a user is improved.
