The process of accessing the wireless terminal into the network mainly comprises the following steps: scanning, authenticating and associating.
Scanning: before joining the network, the wireless terminal first needs to search for the network in the area where the wireless terminal is located, namely, through active scanning or passive scanning. The active scanning is that the wireless terminal requests to join the network by sending a Probe Request frame, and the AP sends a Probe Response frame to respond after receiving the Request frame sent by the wireless terminal; passive scanning is that the AP will periodically broadcast Beacon (Beacon) frames outwards, and the wireless terminal discovers the network by listening to the Beacon frames.
And (3) authentication: when the wireless terminal receives the Probe Response frame of the AP, one of the candidate APs is selected to be associated. Before association, identity authentication is required, and the identity authentication comprises open system authentication and shared key authentication. The Authentication process is that the wireless terminal requests Authentication to a specified AP by sending an authorization Request (Authentication Request) frame; the AP receives and sends an authorization Response (authorization Response) frame in Response.
And (3) association: after the authentication is passed, the wireless terminal side can establish Association with the designated AP, the Association process is that the wireless terminal sends an Association Request (Association Request) frame to Request Association from the designated AP, and the AP receives the Association Request frame and sends an Association Response (Association Response) frame to respond.
In the process of implementing the invention, the inventor finds that the prior art has at least the following problems:
the AP periodically broadcasts Beacon frames during passive scanning, so that the wireless terminal can discover the network by listening to the Beacon frames. Due to the use environment of the WiFi network, a significant portion of APs cannot be powered externally, and must be powered by a storage battery, and since whether to save power directly determines the sustainable operation time of the AP, it becomes crucial to save power of such APs. And the AP broadcasts the Beacon frame outwards periodically, which results in that the AP consumes a large amount of power in transmitting the Beacon frame.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings of the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
The embodiment of the invention provides a method for sending a beacon frame by an access point. Referring to fig. 1, the method may include the following steps:
step S1: the access point acquires a received signal strength indication of a station associated with the access point;
to ensure communication quality and handoff, and to implement dynamic frequency selection or system power control functions, the access point typically requires the stations to report Received Signal Strength Indicators (RSSI) in order for the system to make proper selections and decisions.
In this embodiment, the access point may actively acquire the received signal strength indication of the station associated with the access point without a proxy station or according to a set period, so as to find out the station broadcasting the beacon frame regularly by the proxy.
Step S2: when the received signal strength indication of the station is larger than a first threshold value, the access point sends a proxy request for broadcasting the beacon frame to the station at regular intervals, if a proxy response returned by the station is received, the station is determined as a proxy station, and the proxy station proxies the access point to broadcast the beacon frame at regular intervals.
The RSSI range is typically between-110 dbm and-20 dbm. Generally speaking, if RSSI < -95dbm, the coverage of the current network signal is poor, and almost no signal exists; -95dmb < RSSI < -40dbm, which indicates that the current network signal coverage is very weak; RSSI > 40dbm, which shows that the signal coverage of the current network is better.
In this embodiment, a first threshold value of the received signal strength indication is preset, for example, the first threshold value is-40 dbm. If the received signal strength indication for a station is greater than the first threshold, it indicates that the station is relatively close to the access point, and it may become a proxy access point that periodically broadcasts beacon frames.
After the access point actively acquires the received signal strength indication of the station associated with the access point, whether a station with the received signal strength indication larger than a first threshold value exists is searched:
if the beacon frame is not found, the access point continues to broadcast the beacon frame regularly;
if the beacon frame is found, the access point sends an agent request for broadcasting the beacon frame regularly to the found station.
Specifically, the access point extends a Vendor Specific field (Vendor Specific IE), setting corresponding values for the requesting agent, the granting agent, and the cancelling agent. The access point sends an Action (Action) frame containing a supplier specific field corresponding value as a request agent to the searched station to request the station agent to periodically broadcast a beacon frame. 802.11h incorporates support for Action frames that are used to trigger measurement actions and to ask the workstation to take the necessary actions.
If the station supports the agent to broadcast the beacon frame regularly, the agent response is returned to the access point. Specifically, the station sends an action frame to the access point containing a vendor specific field corresponding value as the consent agent.
Further, if the access point receives a proxy response from more than one station, the station with the best received signal strength indication can be selected as the proxy station to proxy the access point to broadcast the beacon frame periodically. The optimal rssi may refer to the station having the largest rssi.
Step S3: and when the received signal strength indication of the proxy station is smaller than a second threshold value, the access point sends a cancellation proxy message of a periodic broadcast beacon frame to the proxy station, and cancels the proxy station.
In this embodiment, a second threshold for the received signal strength indication is preset, for example, the second threshold is-50 dbm. If the received signal strength indication of the proxy station is less than the second threshold, it indicates that the proxy station is already a little further away from the access point and is no longer suitable as a proxy station for the access point.
The access point sends a cancellation agent message of a periodic broadcast beacon frame to the proxy station, specifically, the access point sends an action frame containing a provider specific field corresponding value as a cancellation agent to the station, and the station stops the proxy access point from periodically broadcasting the beacon frame after receiving the action frame. When the proxy station and access point disassociate, or do not have any interaction for a certain amount of time, the access point will default to the proxy station not to proxy for periodic broadcast beacon frames.
In addition, the method of the present invention may further comprise:
when the proxy station is cancelled, the access point will repeat the steps of S2 and S3, and start the process of finding a new proxy station, i.e. find a station with a received signal strength indication greater than the first threshold among the associated stations. If not found, the access point broadcasts beacon frames periodically, but does not stop the action of finding proxy sites, because the station's received signal strength indication and access conditions are dynamic, and it is likely that a suitable proxy site will be found again in the near future.
