Embodiment Construction

[0024] As described in the background, in the prior art, the STA may switch to the new channel prematurely, find that the signal of the original channel is better, and then switch back to the original channel. Alternatively, the STA may switch to the new channel too late. Channel scanning and frequent channel switching take time, resulting in delays in wifi roaming.

[0025] In the technical solution of the present invention, by receiving the first signal strength indication information from the overlapping access point, the signal strength of the data transmission between the station and the overlapping access point can be obtained, and the second signal strength indication information obtained by the current access point measurement can be Indicates the signal strength of the data transmission between the station and the current access point. By sending the first signal strength indication information and the second signal strength indication information to the station, it c...

Abstract

A wireless roaming method and device, storage medium, and access point equipment, the wireless roaming method includes: receiving first signal strength indication information from overlapping access points, where the first signal strength indication information is used to describe a station using a current channel and The signal strength when the overlapping access point transmits data packets, the overlapping access point overlaps the coverage of the current access point; the second signal strength information is measured and determined, and the second signal strength information is used to describe the the signal strength when the station uses the current channel and the current access point to transmit data packets; sending the first signal strength indication information and the second signal strength indication information to the station, and / or, A handover instruction is generated according to the first signal strength indication information and the second signal strength indication information, and at least the handover instruction is sent to the station. The technical scheme of the present invention can improve the efficiency of wireless roaming.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a wireless roaming method and device, a storage medium, and an access point device. Background technique [0002] In a wifi roaming scenario, a station (STAtion, STA) accesses an original access point (Access Point, AP), and the original AP uses the original channel. When the new AP uses a different channel from the original channel used by the original AP, the station will perform a channel scan, and move to the channel used by the new AP and check whether the current handover is a valid handover. [0003] However, the STA may switch to the new channel too early, find that the signal of the original channel is better, and then switch back to the original channel; or, the STA may switch to the new channel too late. Channel scanning and frequent channel switching take time, resulting in delays in wifi roaming. Contents of the invention [0004] The technical...
