The invention discloses a quick switching method wireless mesh network. To effectively solve problem that soft switching can not be preferably implemented when present switching technology applies in wireless network, the patent, drawing on the experience of emitting fireworks, effectively solve problem of packet loss and retransmission arising from quick switching initiated by terminal; to satisfy demand, wireless network accessing node notifies its peripheral n hop adjacent node in message when finding a new terminal equipment accessing. If switching-out node is n hop neighbor of switching-in node, then the switching-out node notifies by a certain means original network node communicating with the switching-out terminal equipment to rebuild routing relation. When switching-out node finds terminal equipment has already not existed, the switching-out node does not delete terminal equipment instantly but wait for a period of time, during the time if the switching-out node receives message transmitted to the terminal, then broadcasts among m hops. The patent can quickly switch router of terminal equipment especially for wireless mesh network and implement soft switching between network nodes of terminal equipment.
