SCHEDULING METHOD AND SYSTEM, ACCESS POINT AND STATION

摘要

A scheduling method, including: listening to, by a station, a first beacon frame containing a DTIM message used for indicating a beacon interval allocated for each group of stations within a current scheduling period; determining the beacon interval allocated for the station within the current scheduling period according to the DTIM message contained in the first beacon frame; listening to, by the station, within the beacon interval allocated for the station, a second beacon frame containing scheduling information of the current beacon interval used for indicating a time period allocated to each group of stations for data transmission within the current beacon interval; when data transmission is required, transmitting, by the station, data within the time period allocated to the group of the station according to indication of the scheduling information. The present invention improves utilization of time periods, saves time resources and enhances transmission efficiency.

1. A scheduling method, comprising:
listening, by a station, to a first beacon frame, wherein the first beacon frame contains a delivery traffic indication message (DTIM) used for indicating a beacon interval allocated for each group of stations within a current scheduling period; determining, by the station, the beacon interval allocated for the station within the current scheduling period according to the DTIM contained in the first beacon frame; listening, by the station within the beacon interval allocated for the station, to a second beacon frame, wherein the second beacon frame contains scheduling information of the current beacon interval used for indicating a time period allocated to each group of stations for data transmission within the current beacon interval, and at least one group of stations comprises at least two stations; and when data transmission is required, transmitting, by the station, data within the time period allocated to a group to which the station belongs, according to an indication of the scheduling information of the current beacon interval.
