Embodiment Construction

[0041] The implementation manner of the present invention will be specifically described below with reference to the drawings and examples.

[0042] The configuration method of EDCA parameter in a kind of WLAN network of the present invention is as shown in Figure 2, comprises the following steps:

[0043] Step s201, configuring different EDCA parameters on the AP.

[0044] Specifically, different EDCA parameters can be pre-configured on the AP according to different STAs. The default 4 sets of EDCA parameters stipulated by 802.11E and WMM protocols can be used, and other multiple sets of EDCA parameters can also be determined. The service uses specified parameters, or uses different parameters for different services on the specified STA. Among the EDCA parameters corresponding to different STAs, the values ​​of AIFSN, CWmin, CWmax, and TXOPLimit can be set according to different needs.

[0045] Step s202, when the AP receives the request from the STA, it acquires the identi...

Abstract

The invention discloses an enhanced distributed channel access (EDCA) parameter allocation method in a wireless local area network (WLAN), which comprises receiving a request information from a receiving terminal station (STA), and acquiring EDCA parameters corresponding to the STA according to the identification of STA; and adding the acquired EDCA parameters in the response message transmitted from the STA and transmitting. The invention also discloses a kind of access point equipment (AP) for realizing the method. The invention sets up the correlation of the terminal and EDCA parameters and allocates specific EDCA parameter to specific user, so as to provide user-based quality of service (QoS) and realize user-based and service-based QoS service in the WLAN.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and equipment for configuring EDCA (Enhanced Distributed Channel Access) parameters in a WLAN (Wireless Local Area Network, wireless local area network) network. Background technique [0002] WMM (Wi-Fi Multimedia, Wi-Fi Multimedia) and 802.11E protocols are extensions of the 802.11 protocol in terms of QoS (Quality of Service, Quality of Service), and introduce QoS features in the WLAN access layer for the first time. This can meet the low-latency and low-jitter requirements of upper-layer applications such as voice and video in the case of limited bandwidth in the WLAN environment. [0003] In the 802.11 protocol, there is only one sending queue, and all data frames are sent equally; in the WMM and 802.11e protocols, there are 4 AC (Access Categories, access categories) queues, including AC_BK (Background traffic), AC_BE (Best Efrort traffic), AC_VI (Vi...
