Problems solved by technology

[0008] According to the existing power-saving mechanism, when a STA in sleep mode requests cached data on the AP, it needs to send PS-Poll frames to compete with other STAs (STAs in sleep mode and STAs in non-sleep mode) for data transmission Opportunity, when the competition fails, t

Example Embodiment

[0036] In the following, with reference to the accompanying drawings, specific implementations of a wireless station sleep method, device, device, and communication system provided by the embodiments of the present invention will be described in detail.

[0037] The sleep method of a wireless station provided by the embodiment of the present invention, such as figure 2 As shown, it specifically includes the following steps:

[0038] S201: In the awake state, the STA notifies the access point AP that it is currently in the no uplink data transmission phase, and requests to negotiate the sleep time;

[0039] S202: The STA receives a response frame returned by the AP; the response frame carries the time determined by the AP that the STA needs to sleep; the STA needs to sleep for a time that satisfies the STA after the sleep time wakes up and no other STAs are awake at the same time;

[0040] S203. The STA sleeps according to the time carried in the response frame, and wakes up after the ...

Abstract

The invention discloses a sleeping method, device and equipment of a station and a communication system. The method comprises the following steps: when in an awakening state, the STA (station) informs an AP (access point) of the facts that the STA enters an uplink data-free transmission stage, and sleeping time is requested to consult; the STA receives a response frame returned from the AP, wherein the sleeping time which is required by the STA and is determined by the AP is carried in the response frame; the sleeping time required by the STA satisfies the situation that no other STAs are simultaneously in the awakening state when the STA is awakened after the sleeping time; the STA sleeps according to the time carried in the response frame, and is awakened when the sleeping time ends; if the AP carries self-cache data, the awakened STA receives the data from the AP and requests the AP to consult the next sleeping time; and if the AP does not carry the self-cache data, the awakened STA requests to consult the next sleeping time from the AP. By the invention, the energy consumption of STA in the wireless network can be further lowered.

Description

technical field [0001] The present invention relates to the technical field of wireless station power saving, in particular to a dormancy method, device and equipment for a wireless station and a communication system. Background technique [0002] A wireless network (Wireless Lan, WLAN) network has become more and more popular nowadays, and has gradually become an important communication application. Wireless stations (Station, STA) are nodes using WLAN, such as mobile computers using WLAN access, mobile phones or game consoles with WLAN functions, etc., which have the advantages of portability and mobility for traditional clients. While wireless STA brings the convenience of mobility, it also has the disadvantage of limited battery power supply capacity. The power consumption of the WLAN interface of the wireless STA accounts for a large proportion. Therefore, improving the power saving capability of the WLAN interface and reducing power consumption can effectively extend ...
