Embodiments of the present invention provide a feedback method for active scanning of a user terminal and an access point, and relate to the field of communications, where a timer is set in the access point, and after the timer reaches preset time, buffered probe response message can be cleared, thereby further reducing an overhead of channel resources. The feedback method includes: receiving a probe request message from a user terminal, where the probe request message includes scanning time preset by the user terminal; generating and buffering a probe response message of the probe request message; setting and starting a timer corresponding to the user terminal according to the received scanning time preset by the user terminal; and clearing the buffered probe response message after determining that the timer reaches the preset scanning time and the probe response message is not sent to the user terminal.

Feedback method for active scanning of user terminal, and access point

The present disclosure discloses a method, a device and a system for performing NAV control on a node and a node. The method includes: updating a local NAV value to a preset first value when it is determined that a preset first field of a monitored MAC frame carries a first identity, wherein the first value is less than a current local NAV value and the MAC frame of which the preset first field carriers the first identity is transmitted by a TXOP responder after receiving a last MAC frame transmitted by a TXOP holder. The method, device, system and node may enable a hidden station to enter a channel access competition state timely, thereby solving a problem of regional discrimination of a station.

The present invention provides a security identity discovery method, through hiding or omitting MAC addresses of the first station and a second station in a frame for identity discovery between the two stations, adopting identity codes to identify the identities of the two stations and authenticating the identities by using a ciphertext, improves the degree of privacy protection during identity discovery of the stations.
