1. A method for ping pong roaming control, the method being performed by an access point (AP) and comprising:
determining association switching behaviors of a station (STA) based on association and/or disassociation behaviors of the STA;
identifying one or more connection instability events of the STA based on the association switching behaviors of the STA;
recording any connection instability event meeting a filter condition among the one or more connection instability events in a connection instability event list; and
reporting at least one of the one or more connection instability events of the STA to a controller for the controller to identify a ping pong roaming event of the STA between multiple APs, wherein the reporting at least one of the one or more connection instability events of the STA to the controller for the controller to identify a ping pong roaming event of the STA between multiple APs comprises reporting the connection instability event(s) in the connection instability event list in response to a reporting condition being met,
wherein the method further comprises clearing the connection instability event list after the connection instability event(s) in the connection instability event list is(are) reported.
