Channel switching method and device

Abstract

Provided are a channel switching method and device, which relate to the field of communications, and aim to prevent the time being spent on channel switching from being too long and improving the user experience. The channel switching method comprises the following steps: when a channel needs switching, maintaining a connection between a first channel of an access point supporting multiple-input multiple-output (MIMO) and a user equipment, wherein the access point supporting MIMO comprises at least two channels, one of the channels being the first channel (11); determining a channel needing switching from the channels of the access point supporting MIMO (12); and switching the connection between the access point supporting MIMO and the user equipment to the channel needing switching (13). The present invention can be used in channel switching techniques.

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...

Problems solved by technology

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
