Abstract

The embodiment of the present application discloses a method and device for waking up a device, which are used to ensure that in an asynchronous mode, the waking up device can effectively wake up multiple awakened devices, and improve the air interface efficiency when waking up multiple devices. A method for waking up a device in an embodiment of the present application includes: waking up the device to determine a wake-up time displacement of at least one awakened device; generating the at least two trigger messages by the waking up device; The auxiliary wake-up interface sends the at least two trigger messages; the wake-up device generates at least one wake-up frame; The auxiliary wake-up interface of the wake-up device sends the wake-up frame, where the wake-up frame is used to instruct the wake-up device related to the first moment to wake up the main communication interface of the wake-up device. The embodiment of the present application also provides a device.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 201710069855.3 and the invention title "A method and device for waking up a wireless device" filed with the China Patent Office on February 8, 2017, the entire contents of which are incorporated herein by reference Applying. technical field [0002] The present application relates to the communication field, and in particular to a method and device for waking up a device. Background technique [0003] The Institute of Electrical and Electronics Engineers (IEEE) has formulated the IEEE 802.11 standard, and plans to formulate the Internet of things (IoT) standard based on Wireless Fidelity (Wi-Fi), with the goal of integrating Wi-Fi -Fi technology promotion and application to IoT devices and wearable electronic devices.
