Embodiment Construction

[0024] figure 1 A schematic diagram of a network topology structure of a wireless local area network according to an embodiment of the present invention is shown. The WLAN includes an access point 110, stations 120, 122, 124, 130, 132, 134, 140. The stations 120 , 122 , 124 , 130 , 132 , 134 , 140 are non-access point stations located within the coverage area of ​​the access point 110 and governed by the access point 110 . The access point 110 and all the aforementioned stations together form the basic service set. Usually, the identification (identification: ID) of the basic service set 100 is the same as the MAC address of the access point 110 . The WLAN to which the basic service set 100 belongs can be named and identified with a service set ID. Although the non-AP stations shown here are all notebook computers, those skilled in the art can understand that the non-AP stations may also include other devices such as mobile phones and sensors. In this embodiment, the acces...

Abstract

The invention relates to a method for radio resource scheduling in an access point of a wireless local area network. At least one grouping rule is arranged in the wireless local area network. At least one access group is arranged for a number of non access point sites administered by the access point according to each one in at least one grouping rule. The method comprises the steps that at least one grouping message is sent to at least one site in a number of sites; each grouping message comprises information about an access group which is arranged according to at least one grouping rule in all access groups in the wireless local area network; and clear to send frames are sent to a number of sites to be indicated to be wireless resources assigned to an access group which is expected to be protected in all access groups. The method provided by the invention can effectively decompose wireless resource competition between sites, can effectively limit the number of sites which compete at the same time, and provides flexibility of access control of the access groups.

Description

technical field [0001] The present invention relates to a wireless local area network, in particular to a method for scheduling wireless resources in a wireless communication network. Background technique [0002] The application of IEEE 802.11 wireless local area network (especially the application in the home) is increasing day by day, and more and more complicated. Applications such as smart home automation and entertainment products have significantly changed the traffic on home wireless networks. Home business is no longer generated only by desktops or notebooks, but may also be generated by multiple sensors, such as temperature sensors, energy meters, multimedia sensors, etc. This variety results in a wide range of data rates for home traffic (from a few kbps to a few Mbps). This is a challenge for IEEE 802.11 wireless LANs. [0003] As we all know, IEEE 802.11 WLAN was originally designed for best-effort service. Contention-based access is the basis of various tra...
