Wireless local area network access method, access point and wireless local area network system

Abstract

The application discloses a wireless local area network (WLAN) access method, an access point and a WLAN system. the method comprises the following steps: the access point obtains an uplink access conflict; when it is determined that the uplink access conflict exceeds a preset threshold value, the access point broads a first clear-to-send signal to all workstations associated with the access point, wherein the first clear-to-send signal contains a media access control address of a first workstation associated with the access point; and data sent by the first workstation is received. By the above mode, when an obvious uplink access conflict exits in WLAN, a competitive mechanism is avoided and uplink throughput of WLAN is raised.

Description

technical field

[0001] The present application relates to the field of communication technologies, and in particular to a wireless local area network (wireless local area network, WLAN for short) access method, access point (access point, AP for short) and a wireless local area network system. Background technique

[0002] A general wireless local area network (wireless local area network, referred to as WLAN) system includes an access point (abbreviated as AP) and a workstation (station, referred to as STA). Wireless data transmission can be performed between the access point and the workstation to form a wireless network. The internet. Among them, the access point is equivalent to a bridge connecting the wired network and the wireless network. The access point connects all workstations together, and then connects the wireless network to the Ethernet to realize communication between the workstations and the wired network.

[0003] In the prior art, data is transmitted betw...
