Embodiment Construction

[0042] The following combination Figure 1 to Figure 7 Embodiments of the present invention will be described.

[0043] figure 1 and figure 2 It is a schematic diagram of division of WLAN functions between two central APs and small APs in the embodiment of the present invention.

[0044] A traditional WLAN is divided into a physical layer (PHY layer) and a data link layer (English: data link layer). Wherein, the physical layer further includes a physical layer convergence procedure (English: physical layer convergence procedure, PLCP) sublayer and a physical medium dependent (English: physical medium dependent, PMD) sublayer. The data link layer further includes a medium access control (English: medium access control, MAC) sublayer. The MAC sublayer may be coupled to a higher layer, such as a logical link control (English: logical link control, LLC) sublayer of a wired network. Each layer or sub-layer is connected by an interface called a service access point (SAP). For...

Abstract

The invention discloses a method and equipment for associating a WLAN (Wireless Local Area Network) and a central AP (Access Point). The method comprises the steps that: the central AP receives a plurality of association requests, wherein the plurality of association requests are from at least two APs, and the plurality of association requests are the same in BSSID (Basic Service Set IDentifier);the central AP selects one from the plurality of association requests to use as a to-be-replied association request; and the central AP sends a first association response to a to-be-associated AP, wherein the first association response is a reply to the to-be-replied association request, and the to-be-associated AP is an AP in the at least two APs, which sends the to-be-replied association request. A service is provided for a terminal only by the to-be-associated AP, so that the conflict probability is reduced.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and central access point for associating a wireless local area network (English: wireless local area network, WLAN). Background technique [0002] A WLAN generally includes multiple wireless access points (English: access point, AP), so as to provide WLAN services for terminals. A wireless AP is a station that provides associated stations (English: station, STA) access to distributed services via a wireless medium (English: wireless medium). The terminal can be a non-AP station (English: non-AP station) or an AP. [0003] If the WLAN covers a large area, you need to deploy a large number of wireless APs. Each wireless AP has complete WLAN functions. The structure of wireless APs with complete WLAN functions is complex, and a large number of wireless APs leads to high overall cost of WLANs. Contents of the invention [0004] The present application provides...
