Abstract: This application discloses an authentication and association method and system. An access point AP receives an authentication request sent by a station STA that needs to establish a connection to a service device; the AP establishes authentication with the STA; after the STA sends an association request to the service device, the AP receives an authentication result query request sent by the service device, and sends a result of the authentication result query request to the service device, so that the service device determines whether to establish an association with the STA; if the result shows that the STA is authenticated by the AP, the service device can establish an association with the STA; or if the result shows that the STA fails to be authenticated by the AP, the STA cannot establish an association with the service device.

Abstract: Embodiments of the disclosure provide a method, an apparatus, and a device for controlling wireless transmission. A first access point in a first system selects, from access point devices in a second system, one access point as a second access point to which the first access point is attached, and connects to the second access point to send first information to a network device. In so doing, the network device determines, according to the first information and second information that is sent by a user device via an access point to which the user device is attached, a transmission mode and a transmission bandwidth between the first access point and the user device, thereby solving a problem of cross timeslot interference that occurs when wireless local area network systems of different types have an overlapping coverage area and are not synchronized.
