Abstract:
Disclosed in the present application are a method and a device for waking up a wireless device, relating to the field of communication technologies, being able to improve the security of the process of an STA being woken up by an AP and avoid unnecessary power consumption as the STA is maliciously woken up by a malicious device. The specific solution is as follows: a first wireless device sends a first wake-up message, by broadcast or multicast, to first communication interfaces of a plurality of devices, the first wake-up message carrying first identification information, the first wake-up message being used for instructing that the first communication interface of the device identified by the first identification information needs to be in a working state so as to receive a second wake-up message subsequently sent by the first wireless device; and after sending the first wake-up message, the first wireless device sends the second wake-up message to the first communication interface of at least one device, among the at least one device described above, including the second wireless device, the second wake-up message being used for instructing the device identified by second identification information carried in the second wake-up message to wake up a second communication interface of the device.
