Wireless local area network access method, equipment and system

Abstract

The invention discloses a wireless local area network access method and wireless local area network access equipment. The wireless local area network access method comprises the steps of: generating a broadcast message frame which at least comprises channel resource allocation information, wherein the channel resource allocation information at least comprises allocation information for allocating channel resources into a plurality of resource blocks, and a plurality of the resource blocks are used when a plurality of stations are accessed to channels; and sending the broadcast message frame to the stations so that the stations can be accessed to the channels according to the channel resource allocation information in the broadcast message frame. When number of the stations is unchanged, the fact that the same number of stations compete for the same channel is changed into the fact that the same number of stations compete for a plurality of the resource blocks, thereby reducing the possibility of conflicts.

Description

technical field [0001] The present invention relates to the communication field, in particular to a wireless local area network access method, device and system. Background technique [0002] WiFi, the Chinese name Wireless Fidelity, is a technology that can wirelessly connect personal computers, handheld devices (such as PDAs, mobile phones) and other sites to each other. In fact, it is a high-frequency radio signal. Since WiFi is very convenient to use, more and more public places use WiFi to access the network. For WiFi devices, when a station accesses the network through the channel provided by the WiFi device, the station will monopolize a channel, and the number of channels that the WiFi device can provide is limited. When there are a large number of stations wishing to access the network, If the number of channels is not enough, access conflicts will occur between stations, thus limiting the use of WiFi. Contents of the invention [0003] The technical problem to ...
