Claim 7:
8. A device, wherein the device is a node device in a wireless mesh network, the device comprising:
one or more processors;
a storage device for storing one or more programs,
wherein the one or more programs, when executed by the one or more processors, cause the one or more processors to perform the steps of:
obtaining network channel switching information sent by an upper-level parent node device having a connection relationship therewith and sending the network channel switching information to at least a lower-level child node device having a connection relationship therewith; and
switching from a current channel to a target channel according to the received network channel switching information;
wherein obtaining network channel switching information sent by an upper-level parent node device having a connection relationship therewith comprises:
if the network channel switching information is lost, triggering an all-channel scanning to search for the upper-level parent node device having a connection relationship therewith;
obtaining the channel switching latency value and the target channel to be switched to from the upper-level parent node device, and generating the network channel switching information.
