Problems solved by technology

[0006] Still taking STA1 associated with both AP2 and AP3 in Figure 1 as an example, in the prior art, if the link between AP2 and the switch fails, even if the wireless link between STA1 and AP2 is in a normal state, STA1 will fail. Only the wireless link with AP3 can be used to continue transmission, which affects the packet transmission rate of STA

Embodiment Construction

[0054]Take the WLAN networking structure shown in Figure 1 as an example. STA1 is associated with AP2 and AP3 at the same time. AP2 can use the wireless link between AP3 and AP3 as a transfer station between AP2 and the switch to connect AP2 and STA1. The wireless link between STA1 and the switch is connected, so that even when the communication between AP2 and the switch fails, STA1 can continue to use the wireless link between AP2 and AP2 to send and receive messages. Since the bandwidth between the AP and the switch is much higher than the bandwidth of the wireless link between the AP and the STA, the multi-link bandwidth of STA1 can be maintained without affecting the communication of other STAs associated with AP3. Moreover, the wireless links between STA1 and AP2 and AP3 can serve as backups for each other, and when one wireless link fails, it can still access the network through the other.

Abstract

The invention discloses a wireless LAN and an access method thereof. The wireless LAN includes at least two access points AP and a wireless terminal STA related to the at least two access points. The method includes: the related STA of the AP is announced to other AP in the wireless LAN and receive other related STA announced by other AP; upstream message of the STA related to the AP is transmitted to a transfer AP, which is other AP related to the STA at the same time. The invention also discloses a wireless LAN access device and can maintain the transmission speed when STA utilizes a plurality of wireless links and the AP upstream transmission breaks down.

Description

technical field [0001] The present invention relates to a WLAN (Wireless Local Area Network, wireless local area network), in particular to a wireless local area network, a wireless local area network access method and an access device. Background technique [0002] WLAN is the product of the combination of computer and wireless communication technology in the 1990s. It uses wireless channels to access the network, provides potential means for communication mobility, personalization and multimedia applications, and becomes an effective means of broadband access. one. WLAN has the characteristics of flexible networking, low cost, and high speed, and is widely used in fields such as enterprises and education. [0003] A typical structure of WLAN is shown in Figure 1. The switch connects each AP (Access Point, access point) to the wired network, such as AP1, AP2 and AP3 in the figure, and each AP is connected to the BSS (Basic A STA (Station, wireless terminal) in a Service S...
