US 2016/0366633 A1 · ACCESS POINT, STATION, AND BEACON FRAME SENDING METHOD AND SYSTEM

Abstract

The present invention discloses an access point, a station, and a beacon frame sending method and system, relates to the communications field, and resolves a problem of relatively large network overheads caused for purposes of ensuring that in a WLAN system having multiple channels, a STA can quickly access a network. A specific solution is as follows: A first sending unit sends a beacon indication frame on each subchannel of N subchannels, where the beacon indication frame is used to indicate configuration information of a beacon frame; and a second sending unit sends the beacon frame on at least one first subchannel. The present invention is applied to a beacon frame sending process.

Dependent claims

An access point (AP), applied to a wireless local area network (WLAN) system, wherein the WLAN system comprises N subchannels, the N subchannels comprise A first subchannels, N is a positive integer greater than or equal to 2, A is a positive integer less than N, and the AP comprises:

transmitter, configured to send a beacon indication frame on each subchannel of the N subchannels, wherein the beacon indication frame is used to indicate configuration information of a beacon frame;
and
send the beacon frame on at least one first subchannel.

A station (STA), applied to a wireless local area network (WLAN) system, wherein the WLAN system comprises N subchannels, the N subchannels comprise A first subchannels, N is a positive integer greater than or equal to 2, A is a positive integer less than N, and the STA comprises:

a receiver, configured to receive, on any subchannel of the N subchannels, a beacon indication frame sent by an access point (AP), wherein the beacon indication frame is used to indicate configuration information of a beacon frame, and the beacon frame is sent by the AP on at least one first subchannel;
a processor, configured to acquire, according to the beacon indication frame obtained by the receiver, access information required for accessing the AP;
and
access the AP according to the access information that is required for accessing the AP and obtained by the processor.
