Claim:
1. A channel negotiation method, comprising: obtaining channel occupancy information; sending, according to the channel occupancy information, a channel negotiation execution frame that comprises a channel switching manner to a network device in at least one established network such that the network device in the at least one established network switches a current operating channel according to the channel switching manner to generate an idle channel; receiving a channel negotiation execution acknowledgement frame fed back by the network device in the at least one established network; and performing a networking operation on the idle channel, wherein obtaining the channel occupancy information comprises obtaining channel occupancy information indicating that one idle subchannel exists in four subchannels, two occupied subchannels of three occupied subchannels belong to a first established network and a remaining occupied subchannel belongs to a second established network, wherein sending, according to the channel occupancy information, the channel negotiation execution frame that comprises the channel switching manner to the network device in the at least one established network, comprises sending a channel negotiation execution frame that comprises a first channel switching manner to a network device in the first established network, and sending a channel negotiation execution frame that comprises a second channel switching manner to a network device in the second established network, wherein the first channel switching manner is to reduce a bandwidth of two subchannels occupied by the network device in the first established network to a bandwidth of one subchannel occupied, and adjust an operating frequency of the network device with the reduced bandwidth, wherein the second channel switching manner is to adjust an operating frequency of the network device in the second established network, and wherein the adjusted operating frequency of the network device in the first established network and the adjusted operating frequency of the network device in the second established network are operating frequencies that belong to a same channel.
