Description

Wireless access method and device Technical Field The present application relates to the field of communications technologies, and in particular, to a wireless access method and apparatus. Background Wi-Fi protocol is a key technology protocol in wireless local area networks (Wireless Local Access Network, WLANs). With the release of new versions of Wi-Fi protocols, WLANs supporting new versions of Wi-Fi protocols (i.e., the latest version of Wi-Fi protocols) may access more wireless terminals. In a WLAN supporting a new version of Wi-Fi protocol, an Access Point (AP) included therein can implement Access of a wireless terminal supporting an old version of Wi-Fi protocol (i.e., a Wi-Fi protocol other than the latest version of Wi-Fi protocol), and an AP in a WLAN supporting a Wi-Fi 6 protocol can implement Access of a wireless terminal supporting only a Wi-Fi 5 protocol. However, for some wireless terminals, because the technical requirements of the new version of Wi-Fi protocol are not considered during early design and production, the compatibility is poor, and the Beacon (Beacon) message carrying the parameter information of the new version of Wi-Fi protocol, which is broadcast by the AP, and the probe response message carrying the parameter information of the new version of Wi-Fi protocol, which is sent by the AP, cannot be accessed into the WLAN supporting the new version of Wi-Fi protocol, and the related software or hardware is often required to be upgraded to realize that the old version of Wi-Fi protocol is used for accessing the WLAN, so that the management cost is greatly increased. Some network administrators may not bear the increased management cost, and reduce the WLAN supporting the new version of Wi-Fi protocol (for example, wi-Fi 6 protocol) to be used by the old version of Wi-Fi protocol (for example, wi-Fi 5 protocol), so as to meet the access requirement of the wireless terminal supporting the old version of WiFi protocol and having poor compatibility, which greatly reduces the utilization rate of the whole WLAN and reduces the network experience.
