Super-speed wireless local area network channel binding and allocation method based on channel quality

Abstract

The invention provides a super-speed wireless local area network channel binding and allocation method based on channel quality. The super-speed wireless local area network channel binding and allocation method based on the channel quality comprises the first step of monitoring whether communication channels of a single threaded apartment (STA) managed by an application process (AP) are free or not through the AP, starting to control the free channels if the channels are free, and obtaining the number of the free channels, signal-noise ratio and signal interference ratio, the second step of calculating channel signal weight according to the signal-noise ratio and the signal interference ratio and confirming priority of the free channels according to the channel signal weight, the third step of polling the STA managed by the AP through the AP and obtaining business types existing in a local priority array of the STA, the fourth step of dividing priority of the business exiting in the STA through the AP, and the fifth step of allocating the free channels for the STA in a self-adaption mode according to business priority and channel priority with dichotomy through the AP. The super-speed wireless local area network channel binding and allocation method based on the channel quality not only balances the number of business of a network, but also provides more and better channel resources for high priority business. Quality of service (QoS) of the business is ensured and handling capacity of a system is improved.

Description

technical field

[0001] The invention belongs to the technical field of wireless local area network communication, and relates to a channel binding and allocation method, in particular to a channel quality-based ultra-high-speed wireless local area network channel binding and allocation method. Background technique

[0002] Wireless Local Area Network (WLAN) is the product of the combination of computer network and wireless communication technology. As a typical form of wireless IP access, wireless local area network has the advantages of mobile computing, flexible and fast network architecture, low maintenance cost and good scalability. These advantages make WLAN widely used and accelerate the development of wireless local area network. development, and will occupy an important position in the next generation of mobile communication systems. At present, IEEE802.11 has become the mainstream standard of wireless local area network. In 2009, the IEEE802.11-2007 standard was s...

Embodiment 1

[0035] This embodiment provides a channel quality-based ultra-high-speed wireless local area network channel binding and allocation method, which is applied to an infrastructure wireless local area network (WLAN) with APs. The specific application scenarios are as follows: figure 1 As shown, each STA has the ability to support channel bonding and multiplex transmission.

[0036] figure 1 In , BSS represents a basic service set, and BSS is composed of a wireless access point AP and several wireless workstations STA connected to the AP, and the communication between STAs is controlled and coordinated by the AP. The basic function of the AP access point device: responsible for wireless communication management, such as: assigning the right to use wireless channels to wireless nodes; realizing the conversion between wireless communication and wired communication; playing a role similar to wired LAN bridges and routers.

Embodiment 2

[0055] The difference between this embodiment and Embodiment 1 is that in step 5) of the channel quality-based ultra-high-speed wireless local area network channel binding and allocation method, only 3 of the four access categories have data (that is, only 3 A kind of AC send queue to send data), such as Figure 4 As shown, according to the channel quality weight priority from high to low, the first priority access category (AC) is allocated the first 1 / 2 of the total number of idle channels, and the second priority access category (AC) allocates the remaining channels. The first 1 / 2 number of free channels, and the last remaining free channels are given to the third priority access category (AC) in sequence. When the number of channels is small, the access category (AC) with high priority is given priority to transmission data in . Therefore, corresponding to different access categories (AC), the range of the number of idle channels that can be allocated is shown in Table 3....
