1. A method comprising:
obtaining at least one feature of a first access point (AP) by:
receiving, from the first AP, connection information of terminals accessing the first AP, wherein the connection information comprises first identifiers of the terminals;
determining, from the terminals and based on the connection information, target terminals that have requested to access the first AP within a first duration and that have an access status that is abnormal, wherein the target terminals comprise a nomadic terminal or a first terminal that is not on a whitelist of a wireless local area network (WLAN) in which the first AP is located; and
counting a quantity of the target terminals, wherein the at least one feature comprises the quantity; and
detecting, based on the at least one feature and based on a threshold, whether the first AP is a logical edge AP whose signal coverage area reaches an edge of a first signal coverage area of the WLAN.
