Abstract
A terminal wakeup method and an apparatus are disclosed. The method includes: if an access point fails to send a data frame to a station, and the access point fails to send a data frame to the station after channel switching, sending, by the access point, a wakeup signal to the station to wake up the station. According to the method, a data frame loss caused by channel switching can be reduced.
Claims8
A wakeup method, comprising:
- attempting to send, by an access point, a data frame to a station after channel switching;
- determining that the access point fails to successfully send the data frame to the station, and that the access point always fails to send a data frame to the station after channel switching;
- and
- in response to the determination that the access point fails to successfully send the data frame to the station, and that the access point always fails to send a data frame to the station after channel switching, continuing to send, by the access point, a wakeup signal to the station to wake up the station until any data frame is successfully sent by the access point to the station.
