However, in this prior art, since the access point cannot provide data transmission services for the user equipment during the channel switching process of the access point, in order to wait for the access point to complete the channel switching, the user equipment first needs to be disconnected from the access point. The user equipment can re-establish a connection with the access point until the channel switching of the access point is completed.
Therefore, since channel switching takes a long time, and the user equipment cannot perform data transmission within this time, there is a problem of poor user experience

The invention provides a channel switching method and device, relates to the communication field, and aims at preventing time spent on channel switching from being too long and improving user experience. The channel switching method comprises the following steps of when channels need switching, keeping a first channel of an access point supporting multiple input and multiple output (MIMO) and user equipment connected, wherein the access point supporting MIMO comprises at least two channels, and one channel is the first channel; determining the channel needing switching from the channels of the access point supporting MIMO; switching the connection of the access point supporting MIMO and the user equipment onto the channel needing switching. The channel switching method and device can be applied to the channel switching technology.
Description
technical field [0001] The present invention relates to the communication field, in particular to a channel switching method and device. Background technique [0002] In the past, when the user equipment (such as user equipment) was connected to the access point through a channel, the data transmission rate may be difficult to meet the user's requirements due to the deterioration of the channel environment. For applications that are sensitive to the transmission rate (such as Wifi Direct), it is necessary to replace the channel with a better environment to meet the user's speed requirements. [0003] In the prior art, a user may use user equipment to negotiate with an access point to switch channels. Specifically, after receiving the switching request from the user equipment, the access point performs channel switching according to a preset scheme, and after completing the channel switching, the access point reconnects with the user equipment. However, in this prior art, s...
