Abstract

The invention discloses a method and equipment for reducing packet loss when WAPI CPE equipment is switched between APs, including WAPI CPE equipment based on wireless network; WAPI CPE equipment is provided with two wireless radio frequency interfaces A and B, initially WAPI CPE equipment simultaneously Connect to the first AP to establish the first active wireless connection M and the first standby wireless connection S, and use the first active wireless connection M to transmit wireless traffic; when the WAPI CPE switches the wireless connection to the second AP during the movement process, the following Traffic protection method: CPE switches uplink wireless traffic to the first standby wireless connection; CPE disconnects the first active wireless link, and then uses radio frequency interface A to establish a second active wireless link with the second AP; switches CPE uplink traffic to to the second active wireless link; disconnect the first standby wireless link, and use the radio frequency interface B to establish the second standby wireless link with the second AP; the present invention can effectively reduce the traffic loss when the WAPI CPE device performs AP switching Packets, reaching the level where the packet loss time of relevant traffic is less than 50 milliseconds.

Description

technical field [0001] The invention relates to a WAPI wireless network technology, in particular to a method and equipment for reducing packet loss when a WAPI CPE device switches between APs. Background technique [0002] With the extensive development of Internet of Things applications, broadband Internet of Things based on WLAN technology has also been used more and more, especially WLAN networks based on WAPI technology, which are more and more used in some industrial sites, key infrastructure and other fields. Because WAPI (Wireless LAN Authentication and Privacy Infrastructure, wireless local area network authentication and security infrastructure) uses certificates to identify the identity of wireless access points (APs) and wireless terminals (STAs), and performs AP and STA authentication based on the three-element authentication system. Identity authentication ensures the security of wireless access authentication. In these wireless networks, WAPI user-side equipm...
