Method for channel switching in Mesh network, device and mesh network

The embodiment of the invention relates to the field of mesh network communication, and provides a method for channel switching in a Mesh network, a device for channel switching management, a mesh network node and a mesh network system. A channel switching informing frame is received through the mesh node, wherein the informing frame comprises channel switching information of the mesh node and the channel switching information indicates a channel to which the mesh node is switched; and the mesh node is switched to the channel indicated by the channel switching information according to the channel switching information. Compared with the prior art, the method, the device and the mesh network have good universality and can uniformly arrange the channel switching of the mesh node, solve the problem of the network instability caused by master-slave switching and realize the optimal channel allocation of the whole network.
