Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a wireless local area network group polling method based on adaptive service quality assurance, which solves the problem that when there are many service categories in the prior art, the inter-frame intervals of data transmission of each service category are quite different, and low priority The class of business cannot adaptively shorten the inter-frame interval, which will cause unnecessary transmission delay and reduce the technical problem of network throughput.

Embodiment Construction

[0025] figure 2 It is a flow chart of the steps of the present invention, and a kind of QoS-based wireless local area network group polling method provided by the present invention includes:

[0026] Step 210: the initiation and control of the group polling is completed by the group polling coordination point, the group polling coordination point can reside in the access point (AP), and the group polling coordination point groups the service categories according to the priority, and the service category The corresponding relationship between the priority and the group number can be known by the station (STA), or it can be determined and notified by the group polling coordination point to notify the STA. The polling coordination point can adaptively adjust the group polling strategy according to the actual situation and changes of the data service category transmitted by the stations in the network, and the polling is cyclical; The transmission of a certain proportion of low-...

Abstract

The invention discloses a wireless LAN grouping polling method based on self-adaptive service QA, which comprises: regulating grouping polling strategy according to priority of business and business type variation and current state, polling with different contents repeatedly to the grouping that may have business for transmission; the wed site responses the polling according to business type; the web site meet polling condition sends data to target site, the latter responses and receives. This invention can set the frame interval of different priority level same or different, avoids unnecessary transmission delay, and enhances network performance.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a wireless local area network group polling method based on service quality guarantee. Background technique [0002] Wireless local area networks are usually based on the carrier sense multiple access protocol CSMA, and its improvement methods include: channel split reservation multiple access SRMA (split-channel reservation multiple access), collision avoidance multiple access protocol MACA (multiple access with collision avoidance ), improved collision avoidance multiple access protocol MACAW, the bottom acquisition multiple access protocol FAMA (flooracquisition multiple access) and 802.11 and other agreements, the wireless local area network that the present invention refers generally all is based on CSMA agreement. [0003] It is necessary to establish a quality of service (QoS) guarantee mechanism in a wireless local area network. Currently, there are two typical methods...
