Embodiment Construction

[0015] Such as figure 2 with image 3 As shown, the method for dynamically adjusting the sleep duration of STA devices in the present invention includes the steps of: after the STA device finishes fetching the Beacon frame of the associated AP device, it is determined whether the AP device has a buffer frame that needs to be transmitted or whether the STA device needs to send a message to the AP device. Send a frame, if yes, the STA device restores or maintains the original sleep duration, if not, the STA device extends the sleep duration by a certain Beacon frame interval until the sleep duration reaches the upper limit of the sleep duration. According to an embodiment of the present invention, the upper limit of the sleep duration is less than or equal to the ListenInterval value of the IEEE80211 protocol. The Beacon frame number interval is set as the Beacon frame interval between Beacon frames with DTIM information. The original sleep duration is set as the number of Be...

Abstract

The invention discloses a method for adjusting dormant duration of an STA device dynamically. The method comprises following steps of after the STA device finishes grapping the Beacon frames in association with an AP device, judging whether the AP device has caching frames needing to be transmitted or whether the STA device needs to send frames to the AP device; if the AP device has caching frames needing to be transmitted or if the STA device needs to send frames to the AP device, recovering or keeping the original dormant duration of the STA device, and if not, prolonging the dormant duration of the STA device according to a certain Beacon frame number interval until the dormant duration reaches a dormant duration upper limit. The dormant duration of the STA device is adjusted dynamically, the power consumption of the STA device is reduced, and the response delay of frame exchange between the STA device and the AP device is also reduced.

Description

technical field [0001] The present invention relates to the technical field of IEEE80211, in particular to a method for dynamically adjusting the sleep duration of STA equipment. Background technique [0002] Under the IEEE80211 mechanism, STA devices have two power management modes, which are power saving mode and active mode, and the power saving mode has two working states, namely awake state and sleep state. In the awake state, the device enters the normal working state, all circuits work normally, and has complete frame sending and receiving capabilities. In the sleep state, the device enters a low power consumption state, and the transceiver circuit can be turned off to save power. When the device works in the active mode, it can only be in the awake state, while in the power saving mode, the device will switch between the awake state and the sleep state according to the provisions of the IEEE80211 traditional power management mechanism. After a WLAN device conformin...
