Technical field

The present application relates to the field of communications, and in particular, to a method and device for transmitting a WUR message.

Background technique

The Institute of Electrical and Electronics Engineers (IEEE) has developed the IEEE 802.11 standard and plans to develop a wireless fidelity (Wi-Fi) Internet of Things based on the 2.4G/5GHz band. , IoT) standard, its basic characteristics are low power consumption and long distance, the goal is to promote WiFi technology to IoT devices and wearable electronic devices, such as sports bracelets, smart watches and digital medical sensors, etc., generally small size The capacity and capacity of portable batteries are limited, while IoT devices and wearable electronic devices have higher battery life requirements. In the traditional Wi-Fi communication technology, the idle listening channel of the device wastes a lot of power. In order to reduce the waste of power caused by the idle listening channel of the device, the Wi-Fi technology introduces a sleep mechanism, that is, the Wi-Fi module does not. In the case of data transmission, it goes to sleep (ie, the transmitter is turned off). The traditional Wi-Fi sleep mechanism can reduce the power consumption of Wi-Fi. However, if a device is in a dormant state, the access point cannot send a message to the device, and the access point needs to wait until the device wakes up to send a message to the device, which increases the communication delay and does not achieve on-demand ( On-demand) real-time data transmission. In order to reduce the communication delay caused by the traditional Wi-Fi sleep mechanism, the device usually follows a certain sleep mode, periodically wakes up to check whether the access point has data to be transmitted to the device, and reduces the sleep time ratio of the device. The energy consumption of the equipment.

In order to solve the above problem, an ultra-low power wake-up radio/receiver (WUR) module, that is, a wake-up module, is added to the device. The wake-up module coexists with the device's primary communication module (eg, 802.11 module). When there is no message to receive or transmit, the main communication interface of the device's main communication module enters deep sleep, and the wake-up interface of the wake-up module is turned on for ultra-low power listening. The wake-up interface of the wake-up device enables the duty cycle, periodically "wake-sleep", as shown in Figure 1. The wake-up device needs to know the sleep rule of the wake-up device. When the wake-up device has the data of the wake-up device that needs to be sent, the wake-up window of the wake-up device is calculated according to the rest rule, and the wake-up time of the wake-up device is obtained. And send a WUR wakeup message to the device being woken up in the wake up window. Obviously, the above process requires time synchronization between wake-up of the device and wake-up, so that the wake-up device can accurately know the time of the wake-up device. However, there is always drift between the clocks of different devices, if the wake-up device and the wake-up device are The drift between the two is beyond the scope of the wake-up window, and the wake-up device will not receive the WUR message that wakes up the device. In the prior art, the wake-up device needs to periodically send WUR synchronization messages to maintain synchronization of the WUR network.

However, in the prior art, when the mobile phone device is connected to the plurality of wearable devices STA as a mobile hotspot, the mobile phone and the wearable device form a WUR network, and the mobile phone as the AP needs to maintain synchronization with the STA device. In a dense scene, different users' mobile phones Sending a WUR synchronization message to a wearable device consumes a large amount of air interface resources, which reduces the efficiency of air interface usage.
