Station wake-up method, related device, and system

A station wake-up method, comprising:

• receiving, by a wake-up module of a station, in a current awake window, a work time extension indication message sent by a radio access point, wherein the station comprises the wake-up module and a communications module;
• adding, by the station, a new awake window after the current awake window based on the work time extension indication message;
• and
• waking up, by the station, the communications module when receiving, in the current awake window or the new awake window, a wake-up message sent by the radio access point.

A radio access point, comprising one or more processors, wherein the one or more processors are coupled to one or more memories storing program instructions for execution by the processors;

• wherein by executing the program instructions, the radio access point is enabled to perform operations of:
• sending a work time extension indication message to wake-up modules of n stations in associated stations, wherein a station comprises a wake-up module and a communications module, the wake-up modules of the n stations are in an awake state, n is an integer greater than or equal to 1, and the work time extension indication message is used for instructing the wake-up modules of the n stations to add a new awake window after a current awake window;
• and
• sending a wake-up message to a wake-up module of at least one of the n stations, wherein the wake-up message is used for instructing the station to wake up a corresponding communications module, and the wake-up message is sent in a current awake window or a new awake window of the at least one station.

A station, comprising one or more processors, wherein the one or more processors are coupled to one or more memories storing program instructions for execution by the processors;

• wherein by executing the program instructions, the station is enabled to perform operations of:
• receiving, by a wake-up module of the station, in a current awake window, a work time extension indication message sent by a radio access point, wherein the station further comprises the wake-up module and a communications module;
• adding a new awake window after the current awake window based on the work time extension indication message;
• and
• waking up the communications module when receiving, in the current awake window or the new awake window, a wake-up message sent by the radio access point.
