Problems solved by technology

[0004] However, according to the random backoff mechanism in the existing standard, it cannot meet the requirement that when the STA detects other STAs sending probe request frames (Proberequest), it will not send its own probe request frame (Proberequest), but wait for The probe response frame (Proberesponse) replied by the AP needs this kind of demand, so it is necessary to improve the existing random backoff mechanism to meet this demand

Abstract

The invention provides a data communication device and a data communication method. The data communication device comprises a data processing module and a data interaction module, wherein the data processing module generates a first broadcasting message frame and does not generate a random back-off time window when the data interaction module receives a second broadcasting message frame within a preset time threshold, and the type of the second broadcasting message frame is in accordance with that of the first broadcasting message frame; and the data interaction module monitors and receives the second broadcasting message frame and monitors a response message frame of the second broadcasting message frame. With the adoption of an improved random back-off mechanism, the interaction of the message frames can be reduced to the greatest extent when numerous terminals are accessed to a wireless local area network, so that the conflict probability due to the interaction of the numerous message frames is reduced, and the connection efficiency of initial network access of the wireless local area network is improved.

Description

Technical field [0001] The present invention relates to the field of wireless communication technology, and in particular, to a data communication device and a data communication method. Background technique [0002] A new task group 11ai was established in the IEEE (Institute of Electrical and Electronics Engineers) 802.11ah project group to study how the terminal (station, STA) can establish a fast initial connection with the access point (accesspoint, AP). The requirements are 100 terminals can establish an initial link with the AP at the same time within 1s. In order to reduce the interaction of network access signaling and the possibility of conflicts of network access signaling, improvements have been made to network discovery. For example, when an STA hears another STA sending a probe request frame (Proberequest), it does not send its own The probe request frame (proberequest), but the probe response frame (Proberesponse) waiting for the AP to reply, so as to avoid multip...
