Embodiment Construction

[0259] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0260] See figure 1 As shown in , it is a schematic diagram of the network architecture involved in the multi-site access method provided in some embodiments of the present invention. The network architecture includes an access point 120 and at least two stations 140 .

[0261] The access point 120 (English: Access Point, AP for short) and each station 140 (English: STation, short: STA) are connected through a wireless network, and the access point 120 and each station 140 may be located in the same local area network.

[0262] For example, the access point 120 may be a wireless router in a local area network, and the station 140 may be a wireless device in the local area network, such as a smart phone, a smart TV, a tablet computer, ...

Abstract

Embodiments of the present invention provide a multi-site access method, device and system, and relate to the field of network technology. The method includes: generating matching rules and access rules according to the current network characteristics, the matching rules are used to restrict the stations that are allowed to access the channel, and the access rules are used to restrict the access methods and access rules of the stations when accessing the channel. Parameter; send a trigger frame to the station, and the trigger frame carries matching rules and access rules. The invention obtains the current network characteristics at the access point, generates matching rules and access rules, so that the station can perform uplink access according to the matching rules and access rules; When the number of nodes is large, high-priority services are likely to starve to death, or low-priority packets conflict with high-priority packets, which reduces the service quality of high-priority services; the effect of guaranteeing service quality and user experience is achieved .

Description

technical field [0001] The present invention relates to the field of network technologies, and in particular, to a multi-site access method, device and system. Background technique [0002] The next-generation wireless local area network (English: Wireless Local Access Network, WLAN for short) will be oriented to highly dense and complex scenarios, and needs to support increasingly diverse user features and constantly enriched service features. This requires that the uplink access technology of the next-generation WLAN should be treated differently according to user and network characteristics, and different uplink access strategies should be adopted. [0003] The Enhanced DCF Channel Access (English: Enhanced DCF Channel Access, referred to as: EDCA) protocol is based on the distributed point coordination function (English: Distributed Coordination Function, referred to as: DCF) protocol through the quality of service (English: Quality of Service, referred to as: : QoS) su...
