Embodiment 1

[0081] see Figure 1-a , this embodiment provides a scheduling method that can be used for scheduling STAs by an AP in a WLAN, and the method includes:

[0082] S11: The station listens to the first beacon frame, and the first beacon frame includes delivery transmission indication information DTIM information, which is used to indicate the beacon period allocated to each group of stations in the current scheduling period.

[0083] During implementation, the station may wake up at the moment when the first beacon frame is sent.

[0084] S12: The station determines the beacon period allocated to the station in the current scheduling period according to the DTIM information contained in the first beacon frame;

[0085] S13: During the beacon period allocated to the station, the station listens to the second beacon frame, and the second beacon frame contains the scheduling information of the current beacon period, which is used to indicate that each group of stations in the curren...

Embodiment 2

[0092] see figure 2 , this embodiment provides a scheduling method, in which each time period is assigned to a group, and at least one group includes at least two sites, the method includes:

[0093] 201: AP (Access Point, access point) sends the first beacon (beacon) frame according to the preset first period, and the first beacon frame contains DTIM (Delivery Traffic Indication Message, delivery transmission indication information) information, used to indicate The beacon period to which each group of stations is assigned in the current scheduling period;

[0094] Wherein, a scheduling period includes multiple beacon periods, and each group is scheduled once in a scheduling period, and only once. For a schematic diagram of the scheduling cycle, see image 3 shown.

[0095] It should be noted that the AP may divide each station into different groups according to scheduling basis information reported by each station, such as QoS (Quality of Service, service quality) inform...

Embodiment 3

[0150] see Figure 11-a , this embodiment provides a scheduling method that can be used for scheduling STAs by an AP in a WLAN, and the method includes:

[0151] S31: The station listens to the third beacon frame, and the third beacon frame includes delivery transmission indication information DTIM information, which is used to indicate the beacon period allocated to each station in the current scheduling period;

[0152] S32: The station determines the beacon period allocated to the station in the current scheduling period according to the DTIM information included in the third beacon frame;

[0153] S33: During the beacon period allocated to the station, the station listens to the fourth beacon frame, and the fourth beacon frame contains the scheduling information of the current beacon period, which is used to indicate that each station is allocated to transmit data in the current beacon period Each time period is assigned at least one station, and at least one time period ...

Abstract

The invention provides a scheduling method and system, access points and stations, and relates to the field of communications. The scheduling method comprises the following steps: a. the stations monitor a first beacon frame which includes a DTIM for indicating the beacon periods distributed to each group of stations in the current scheduling period; b. the beacon periods distributed to the stations in the current scheduling period are confirmed according to the DTIM included in the first beacon frame; c. the stations monitor a second beacon frame which includes a scheduling message for indicating the data transmission time frames of each group of stations in the frame period distributed to the stations, wherein at least one group of stations include two stations; d. the stations transmit data in the time frame distributed to the group of the stations according to the indication of the scheduling message in the current beacon period when data transmission is needed. By means of the scheduling method and system, the utilization rate of the time frames is improved, time resource is saved, and transmission efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a scheduling method and system, as well as an access point and a station. Background technique [0002] With the development of communication technology, people put forward new requirements for wireless network technology, namely high speed, large scale and high throughput. The number of user STAs (stations) in the wireless local area network is also increasing, and the competition for the stations to access APs (Access Points, Access Points) becomes more intense. [0003] Because the contention-based access method will cause problems such as collisions, the current scheduling method mainly divides a frame into several time periods, and each time period is allocated to a station. If the station needs to transmit data, the Stations access the channel during their corresponding periods and transmit data. [0004] The existing scheduling method allocates a time peri...
