Data packet sending method and access point

Abstract

The embodiment of the invention provides a data packet sending method and an access point, wherein the data packet sending method comprises the following steps of: at the beginning of a period, setting a local inter-frame spacing interval as a first numerical value by the access point, wherein the first numerical value is less than a preset second numerical value; setting a contention window as zero; calculating at the beginning of the period, during a duration time of a special flow, when the idle time of a channel reaches the preset inter-frame spacing interval, controlling the sending of a data packet of a special type; after the duration time of the special flow from the beginning of the period, setting the inter-frame spacing interval as a preset inter-frame access parameter, wherein the numerical value of the preset inter-frame access parameter is more than or equal to the second numerical value; and modifying the contention window as a preset window parameter value. By using the technical scheme provided by the embodiment of the invention, an AP (Access Point) can be successfully contended and accessed to the channel; and the data packet of the specific type can be sent in time.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a data packet sending method and an access point. Background technique [0002] With the development of wireless communication technologies, people pay more and more attention to wireless local area network (Wireless Local Area Network, WLAN) technology. A WLAN generally includes an access point (AccessPoint, AP) and multiple stations (Station, STA), and both the AP and the multiple STAs compete for an access channel. The AP and each STA will monitor the channel when they need to access the channel. If the channel is idle and the duration is greater than the distributed inter frame space (DCF Inter Frame Space, DIFS), then the AP or STA will access the channel; if the channel is busy, Then the AP or STA continues to monitor the channel until the time interval of DIFS when the channel is idle, and starts the random backoff process, that is, randomly selects a value from 0 t...

AI Technical Summary

Problems solved by technology

[0006] Since different priorities are set for different types of data streams on the STA and the AP, when both the AP and the STA have high-priority data streams (that is, voice streams and video streams) to be sent, it is difficult to guarantee the priority of the AP on the AP. Voice streams and video streams can compete for access channels, making service quality unguaranteed
