When an access point notifies a user equipment of a communications network supported by the access point, the access point also notifies the user equipment of priority information of the access point, so that the user equipment can select an access point that an operator expects the UE to select, to be connected to the communications network, thereby avoiding inconsistency between an access point, which is randomly selected by the user equipment to be connected to a communications network, and an access point that a communications network operator expects the UE to select.
