A wireless network access method, related equipment and system

Abstract

The embodiment of the present invention discloses a wireless network access method, including: obtaining receiver sensitivity capability value information sent by a first type of station in the process of requesting to access the wireless network; generating a broadcast frame according to the receiver sensitivity capability value information , and broadcast the broadcast frame; the broadcast frame includes time information respectively indicating data communication with the first type of station and the second type of station; wherein, the first type of station includes a station that supports dynamic change of receiver sensitivity; The second type of stations includes stations that do not support dynamically changing receiver sensitivity. The invention also discloses an access point device, a station device and a wireless network access system. By adopting the invention, the new and old station devices can obtain the same data transmission opportunity, thus solving the problem caused by changing the sensitivity mechanism of the receiver. Unfairness leads to technical problems of inefficient use of frequencies, improves the efficiency of spectrum use, and increases throughput in the region.

Description

technical field [0001] The present invention relates to the communication field, in particular to a wireless network access method, related equipment and system. Background technique [0002] With the advancement of information communication technology, various wireless communication technologies have recently been developed. Among these wireless communication technologies, wireless local area network (WLAN) is a wireless communication technology that can be used in homes or businesses or in areas that provide specific services by using portable terminals (such as smart mobile terminals, tablet computers, portable multimedia players, etc.) way of surfing the web. [0003] Currently, 802.11 establishes a next-generation wireless high-fidelity (Wireless Fidelity, Wi-Fi) technology research group—high efficiency wireless local area network (High Efficiency WLAN, HEW), so as to improve the throughput of current wireless communication. Since HEW application scenarios are denser...

Problems solved by technology

[0004] If there are new STAs (that is, stations that support dynamic change of receiver sensitivity) and old STAs (that is, stations that do not support dynamic change of receiver sensitivity) in a certain area, then the mechanism of CCA is adopted in the area, and the old STAs The interference probability of the new STA is greater than that of the new STA, such as figure 1 The schematic diagram of the communication between the access point and the station in the prior art is shown, the signal strength received by the station STA1 and the station STA2 is -70dbm, and the signal strength received by the access point AP1 and the access point AP2 respectively from STA1 and STA2 is -50dbm, if STA1 supports dynamic change of receiver sensitivity, but STA2 does not support dynamic change of receiver sensitivity, then when STA1 communicates with AP1, STA2 cannot communicate with AP2, because STA2 perceives that the channel is busy according to the CCA mechanism, and STA1 will not, this mechanism of changing the sensitivity of the receiver brings unfairness, seriously affects the efficiency of spectrum use, and reduces the throughput in the area
