Problems solved by technology

[0004] However, according to the random backoff mechanism in the existing standard, it cannot meet the requirements that when the STA detects that other STAs send probe request frames (Probe request), it will not send its own probe request frame (probe request). It is to wait for the demand of the probe response frame (Proberesponse) replied by the AP, 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 technical field of wireless communication, in particular, to a data communication device and a data communication method. Background technique [0002] In the IEEE (Institute of Electrical and Electronics Engineers) 802.11ah project team, a new task group 11ai was established to study how the terminal (station, STA) establishes a fast initial connection with the access point (access point, AP), and the proposed requirements It is within 1 second that 100 terminals can establish initial links with the AP at the same time. In order to reduce the interaction of network access signaling and the possibility of network access signaling conflicts, network discovery has been improved. For example, when a STA detects that other STAs send probe request frames (Probe request), it does not send itself The probe request frame (proberequest), but waits for the probe response frame (Probe response) replied by the AP, thus avoidin...
