Problems solved by technology

Because the access point does not know that the station has entered power saving mode, the access point sends data frames to the station as usual, resulting in the loss of data frames

Abstract

The invention discloses a terminal wake-up method and device. The method includes: if the access point fails to send data frames to the station, the access point determines whether the access point fails to send data frames to the station after the last channel switch; if the access point determines that after the channel switch, the access point sends the station If all data frames fail to be sent, the access point sends a wake-up signal to the station to wake it up. The above method can reduce data frame loss caused by channel switching.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for waking up a terminal. Background technique [0002] The station (English: station) will enter the power saving state when the wireless local area network (English: wireless local area network, WLAN) communication module has no data communication, that is, turn off the WLAN communication module. No data communication may mean that the station does not receive data frames and management frames sent by other stations (such as access point (English: access point, AP)), and the station does not have data frames or management frames that need to transmit data. Before turning off the WLAN communication module, the station will send a null data (English: null data) frame with a power saving flag to the access point to notify the access point that the station enters a power saving (English: power save) mode. Wherein, the power saving flag of the empty data frame ...
