Problems solved by technology

In general, the more workstations waiting to be accessed, the more likely the conflict will reoccur
Therefore, when too many users access the access point concurrently in WLAN, there will be obvious access conflicts, which will lead to a huge drop in WLAN uplink throughput.

Embodiment Construction

[0024] The following description will be made in conjunction with the accompanying drawings and specific implementation manners.

[0025] figure 1 It is a schematic structural diagram of a wireless local area network (WLAN) system provided by an embodiment of the present invention. see figure 1 , in this embodiment, the WLAN includes an access point 110 and a plurality of workstations 120, wherein the plurality of workstations 120 includes at least a first workstation 121 and a second workstation 122, and the plurality of workstations 120 are associated with access to the Access point 110.

[0026] Generally, sending data from the workstation 120 to the access point 110 is called uplink communication, and sending data from the access point 110 to the workstation 120 is called downlink communication. When at least two workstations 120 send data to an access point 110 at the same time, because the access point 110 can only receive the data of one workstation 120 at a time, so...

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...
