Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a wireless local area network group polling method based on a fixed service quality assurance strategy, which solves the problem that in the prior art, when there are many service categories, the inter-frame intervals of various classified service data transmissions differ greatly and are relatively low. The priority business category has a long inter-frame interval, which will cause unnecessary transmission delay and reduce the technical problem of network throughput

Embodiment Construction

[0021] Various preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] figure 2 It is a flow chart of the steps of the present invention, and the QoS-based WLAN group polling method provided by the present invention includes:

[0023] Step 210: The initiation and control of the group polling is completed by the group polling coordinating point, the group polling coordinating point can reside in the access point (AP), and group the service categories according to the service category priority, the service category priority The corresponding relationship with the group number is known by the station (STA). The group polling coordination point determines the group polling strategy and polls each group according to the strategy. The polling is cyclical and repeated;

[0024] Step 220: The STA responds to the group polling according to the priority of the service category of the data to be transmitted ...

Abstract

The invention discloses a wireless LAN grouping polling method based on fixed service QA, which comprises: determining grouping polling strategy according to priority of business to take polling with may different contents repeatedly to the part or all grouping; 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 and retreat window 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 protocols, the wireless local area network referred to in the present invention is generally all based on the CSMA protocol. [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: the...
