Indication method of downlink service data and device

Abstract

The invention provides an indication method of downlink service data and a device. The method comprises the following steps: a first station STA associated with a wireless access point AP controls anawakening receiver of the first STA to wake up within a preset first monitoring interval, and receives an awakening beacon frame sent by the AP, wherein the awakening beacon frame comprises an indication field for indicating whether the AP has the downlink service data which are going to be transmitted to the first STA; the first STA controls a master radio of the first STA to be free from wakingup within a second monitoring interval to receive the beacon frame sent by the AP; and according to the indication field, the first STA determines whether the AP has the downlink service data which are going to be transmitted to the first STA. With the method provided by the invention, the MR of the first STA is free from waking up within the second monitoring interval to receive the beacon framebroadcasted by the AP, thus, wake-up frequency of the MR is reduced greatly, and power consumption of the first STA is reduced.

Description

technical field [0001] The present application relates to communication technologies, and in particular to a method and device for indicating downlink service data. Background technique [0002] In a Wireless-Fidelity (WiFi for short) network, a considerable part of the energy of the receiving end device is wasted in idle listening when there is no received signal, that is, when the station (Station, STA for short) does not send and receive messages, if the Monitoring the channel will consume a lot of energy, so the sleep mechanism (SleepSchedule) is introduced in the communication standard so that the STA can enter the deep sleep (Deep Sleep) state when there is no data to send and receive, so as to reduce the energy consumption of continuous monitoring. However, when the STA is in deep sleep, the access point (Access Point, AP for short) cannot communicate with the STA, and the transmission between the two can only be performed after the STA wakes up, which may cause a cer...

AI Technical Summary

Problems solved by technology

[0004] However, for some sites with WUR that have very strict power consumption requirements, such as sites equipped with button batteries (such as sensors), the downlink service data sent by the AP to this type of site accounts for a very small proportion of the entire data service transmission. If the above-mentioned WUR is equipped The MR of the site wakes up to receive beacon frames within the listening interval according to the 802.11 mechanism. The MR wakes up frequently, and the power consumption of the site is relatively high.
