1. A network channel switching method performed by a node device in a wireless mesh network, comprising:
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.
