Description

Wake method and device

This application claims priority from a Chinese patent application filed with the Chinese Patent Office on June 08, 2018, with application number 201810589977.X, and with the application name "A Wake Method and Device", the entire contents of which are incorporated herein by reference. in.

Technical field

Embodiments of the present application relate to the field of communication technologies, and in particular, to a wakeup method and device.

Background technique

In a wireless fidelity (WiFi) network, a considerable part of the device ’s energy is wasted during idle listening when no signal is being received. In order to reduce energy wasted while the device is listening, existing technologies use low power wake-up radios (Low Power Wake Up Radio (LP-WUR) technology reduces equipment idle listening energy waste.

The core idea of LP-WUR is that the receiving end equipment (such as the station STA) includes a Wake Up Radio (WUR) part in addition to the primary transceiver module (PCR). As shown in Figure 1, when the PCR is turned off, WUR wakes up and starts to work. When other devices (such as the access point AP in Figure 1) need to communicate with devices with WUR and PCR (such as the station STA in Figure 1) During communication, the access point (Access Point, AP) sends a wake-up frame to the WUR of the station (Station, STA). After the WUR receives the wake-up frame correctly, the PCR will be awakened to perform normal transmission and reception of wireless frames, and the WUR can transfer itself. Hibernate or shut down.

When the WUR of the STA receives the wake-up frame sent by the AP, there are two possible wake-up modes: Mode 1. After the WUR of the STA receives the wake-up frame, it wakes up its PCR. PCR passes the channel competition. After the competition is successful, it sends a response frame to the AP in order to Notify the AP that the PCR has entered the awake state; Mode 2. The AP sends a wake-up frame to the WUR of the STA, and waits for a certain delay to send a trigger frame or data frame to the STA's PCR. After the PCR receives the trigger frame or data frame sent by the AP, Send a response frame to the AP to notify the AP that the PCR enters the awake state.

In the prior art, the AP can configure the STA to use the wake-up mode 1 or the wake-up mode 2 to notify the AP that the main transceiver module has entered the awake state, but the wake-up method in the prior art cannot effectively manage multiple wake-up modes, and low network resource utilization exists. The problem of large energy consumption.

Summary of the Invention

The first response frame is used to notify the AP that the main transceiver module enters the awake state. The second wake-up mode includes the STA waiting to receive the wireless frame sent by the AP. Then, a second response frame is sent to the AP, and the second response frame is used to notify the AP that the main transceiver module enters the awake state; the first duration is greater than 0Based on this solution, within the first time period after the STA receives the wake-up frame, if it does not receive the wireless frame sent by the AP, it can use the first wake-up mode to notify the AP that the master transceiver module has entered the awake state or the master transceiver module has woken up from the awake state. Switching to the off state does not need to wait for the wireless frame sent by the AP as in the prior art, can avoid unnecessary energy waste, and can increase the probability of successful communication between the AP and the STA by switching to the first wake-up mode.

User equipment such as mobile phones and mobile phones can be connected to the Internet. The specific form of the STA is not limited in the embodiments of the present application.

Exemplarily, as shown in FIG. 1, when the STA has no information to transmit and receive, the main transceiving module (for example, PCR) of the STA is turned off, and the WUR module of the STA wakes up and starts to work. If the AP needs to communicate with the STA, the AP first sends a wake-up frame to the STA's WUR module. After the WUR module correctly receives the wake-up frame, it wakes up the STA's main transceiver module PCR, and then the WUR module goes to sleep or shut down. The main transceiver module PCR in the awake state may use the first wake-up mode or the second wake-up mode to inform the AP that the main transceiver module PCR has entered the awake state, and the AP may communicate with the main transceiver module PCR in the awake state. After the communication between the main transceiver module PCR and the AP is completed, the main transceiver module PCR will enter the off state again, and the WUR module wakes up and continues to listen for the wake-up frame to wake the main transceiver module PCR again, which can effectively reduce the energy of the device during idle monitoring.

Energy wasted while listening; when the main transceiver module is off, the WUR module wakes up and starts to work. After receiving the wake-up frame sent by other devices (such as AP), the WUR module wakes up the main transceiver module and sends After the module enters the awake state, the WUR module goes to sleep or shut down. It can be understood that the main transceiver module in the embodiment of the present application in the off state is different from the main transceiver module in the state of sleep in the prior art.
