Problems solved by technology

But when this AP is in an environment where multiple APs share wireless bandwidth, since all APs will send Beacon, if each AP sends Beacon at a period of 100ms, there will be too many Beacon packets in the entire wireless environment , because the transmission rate of Beacon packets is the lowest rate and the highest priority, when too many Beacon packets are sent, the wireless resources in the entire space are largely occupied by Beacon packets, and the normal data transmission efficiency cannot Get wireless resources reasonably

[0068] Such as figure 1 As shown in the flowchart of the first embodiment of the present invention: a method for automatically adjusting the period of a wireless local area network device (AP) 1000 sending a Beacon frame, the wireless local area network device (AP) 1000 includes: a Beacon frame detection module 200, a Beacon Frame comparison module 300, Beacon frame adjustment module 400, Beacon frame transmission module 500, described method comprises the following steps:

[0069] S200: The Beacon frame detection module 200 detects all Beacon frames within the data coverage;

[0070] S300: The Beacon frame comparison module 300 compares the sending period of the Beacon frame of the network device (AP) 1000 with the average sending period of all Beacon frames within the data coverage within a certain period of time;

[0071] S400: The Beacon frame adjustment module 400 adjusts the sending period of the Beacon frame of the network device (AP) 1000 according to the comparison r...

[0081] On the basis of the method for automatically adjusting the period of the Beacon frame sent by the local area network device / wireless local area network device (AP) 1000 in Embodiment 1, as image 3 It is shown in the schematic flow chart of the second embodiment of the present invention:

[0082] Preferably, in the method for adjusting the periodicity of a wireless local area network device (AP) 1000 sending a Beacon frame, the wireless local area network device (AP) 1000 also includes a Beacon frame initialization module 100, and the step S200 includes a step S100 before the step: The Beacon frame initialization module 100 sets the initial period T of the Beacon frame as T0.

[0083] Preferably, in the method for adjusting the periodicity of the wireless local area network device (AP) 1000 to send Beacon frames, the step S100 includes the step S150: the Beacon frame initialization module 100 sets the Beacon frame detection module 200 to wait at least 30 seconds, Then ...

no. 3 example

[0095] Such as Figure 5 As shown in the schematic diagram of the working state of the present invention, the steps of STA and AP:

[0096] Initially, the initial transmission period of Beacon frames is determined by the administrator configuration, assuming T0; the actual transmission period T can only be dynamically adjusted within the range of (T0 / N, T0*N), and the dynamic range factor N is configurable. (Note: The existence of the dynamic range factor N is to prevent the AP from having a very long or very short Beacon transmission cycle due to the dynamic adjustment algorithm when there are too many APs in the wireless environment. Because if there are too many APs in the entire wireless space An AP that does not support this invention may invalidate the algorithm, resulting in a very long or very short Beacon sending cycle for APs that support this invention, and the dynamic range factor N can prevent this from happening.)

[0097] Step 1), at the beginning, the period T...

Abstract

The invention discloses a data sending method. The method comprises the steps that S200, a Beacon frame detection module detects all Beacon frames in a local area network; S300, a Beacon frame comparison module compares a sending cycle of the Beacon frames in a local area network device with an average sending cycle of all Beacon frames in the local area network within certain time period; S400, a Beacon frame adjusting module adjusts the sending cycle of the Beacon frames of the local area network according to a comparison result of the Beacon frame comparison module; and S500, a Beacon frame sending module sends the Beacon frames according to the adjusted sending cycle of the Beacon frames of the local area network device.

Description

technical field [0001] The present application relates to the field of local area network / wireless local area network technology, and in particular to the adjustment of the Beacon frame transmission period on the WIFI network. Background technique [0002] A WLAN is mainly composed of a station (Station, STA), an access point (Access Point, AP), a wireless medium (WirelessMedium, WM) and a distributed system (Dis-tribution System, DS). [0003] station (STA). The STA is generally a client in a WLAN, which can be a computer equipped with a wireless network card or a smart phone with a WiFi module. STA can be mobile or fixed, and is the most basic unit of WLAN. [0004] In a wireless local area network (WIFI network), all communication must pass through the AP (Access Point, access point), and the AP is responsible for sending Beacon frames (beacon frames) to announce the existence of a certain wireless network, and the range of the Beacon frame That is the basic service ar...
