Disclosed in the present invention are a fast switching method, a fast switching system, a client and an access point (AP) in a wireless communication system. The method comprises: when a client decides to switch, said client establishes, via its current AP, virtual links with candidate APs, said virtual links including a communication link between said client and said current AP and communication links between said current AP and said candidate APs; said client sends, via said virtual links, a probe request to said candidate APs and receives probe responses of said candidate APs; said client selects, according to the probe responses of said candidate APs, a target AP from said candidate APs; said client sends, via said virtual link, an association request to said target AP and receives an association response of said target AP; and when said client starts switching, said client terminates the communication with said current AP and switches to said target AP. Using this method can greatly reduce the switching time. |
