A WIFI event recalling sub-device receives a WIFI recalling event message, and adds the WIFI recalling event message to the application event message queue after the WIFI recalling event message is received.
The application event message is generated by the main thread in the wireless communication device by the application recalling sub-device controlling the service logic thread.
The WIFI recalling event message is generated by an application program.
In an embodiment, the application event message may be an event generated by an upper layer application of the wireless communication device initiatively. For example, the application event message AF_EVT_AP_STOP is generated when the wireless communication device cancels AP mode.

The wireless communication device may also support a working station mode STA-Mode, which may be understood as a working station in a certain network grid, i.e., the client side. When a WIFI chip in the wireless communication device provides an STA-Mode function, the wireless communication device may be connected to another network grid. The AP-Mode is provided to connection of a mobile terminal and the like, and the STA-Mode is configured to provide a data uplink service of the network.
