Problems solved by technology

In this way, the STA will frequently switch between sleep and wake-up, and each switching process will consume a certain amount of power. However, in fact, when most STAs wake up, the AP does not cache data packets, making excessive Consumes the power of STA, resulting in low power saving efficiency of STA

Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] First, a brief description will be given of related concepts involved in the method provided by the embodiment of the present invention.

[0025] Beacon frame (Beacon frame): It is a type of data frame in the WLAN, which is sent periodically by the AP, so that the STA can discover the WLAN and determine whether there is a data message cached in the AP.

[0026] Quiet Information Element (Quiet IE): An IE (Information Element, Information Element) defined...

Abstract

The embodiment of the invention provides a terminal wake-up method and device and wireless access equipment. The terminal wake-up method includes the steps of determining a silent period longer than an obtained monitoring interval of a wireless terminal if it is determined that the duration of the wireless terminal in a sleep state is longer than or equal to a first preset duration; when it is determined that the wireless terminal wakes up a monitoring beacon frame but does not cache data messages sent to the wireless terminal, sending information in the silent period to the wireless terminalto inform that the time interval for waking up the monitoring beacon frame next time is equal to the silent period. By means of the scheme, the power saving efficiency of the terminal equipment can beimproved.

Description

technical field [0001] The present invention relates to the technical field of wireless networks, in particular to a terminal wake-up method, device and wireless access equipment. Background technique [0002] When a user accesses a WLAN (Wireless Local Area Network, wireless local area network) through a STA (Station, wireless terminal), the STA is often required not to be fixed at a specific location. Therefore, the STA is usually a portable electronic device, such as a notebook computer, a tablet computer, Mobile phones, etc. These electronic devices are powered by batteries and provide users with mobile operation functions. [0003] In the currently commonly used WLAN networking environment, the STA is connected to an AC (Access Controller, access controller) through an AP (Access Point, access point) to implement access to the WLAN. Fully considering the power saving of STA, the wireless transmission protocol stipulates that after the STA accesses the WLAN, if there is...
