Active scanning method and device

摘要

Disclosed are an active scanning method and an active scanning device. The active scanning method in a wireless LAN comprises the steps of: a second station (STA) receiving a first probe request frame which has been broadcast by a first STA; and the second STA broadcasting a second probe request frame. The second probe request frame may include a probe request frame detection field, and the probe request frame detection field may indicate that the second STA has received the first probe request frame. Accordingly, a probe response frame is broadcast to a plurality of STAs, thus simplifying a scanning procedure.

主权项

1. An active scanning method in a wireless local area network (WLAN), the active scanning method comprising:
receiving, by a second station (STA), a first probe request frame broadcasted from a first STA; broadcasting, by the second STA, a second probe request frame to an AP (access point), wherein the second probe request frame includes a probe request frame detection field, and wherein the probe request frame detection field indicates that the second STA has received the first probe request frame; and receiving, by the second STA, a beacon frame or a probe response frame from the AP, wherein the probe response frame is a response to the second probe request frame, and wherein when the same information should be transmitted to the first STA and the second STA as a response to the first probe request frame and the second probe request frame, the AP broadcasts the probe response frame.
