Direct connection link communication method and related equipment and system

Abstract

An embodiment of the invention discloses a direct connection link communication method and related equipment and system. The method includes: a first station supporting a direction connection link building function transmits a direct connection link building request frame to an access point, and the first station receives a direct connection link building response frame transmitted by the access point, wherein the direct connection link building response frame comprises instruction information for instructing the first station to be encapsulated into the access point; the first station is encapsulated into the access point according to the instruction information and performs direct connection link communication with the second station. By the method, a direct connecting link communication building mechanism can be provided, and direct link communication between a station supporting a DLS function and another station which does not support the DLS function can be built under the circumstance that only the access point and one station support the DLS function.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a direct link communication method and related equipment and systems. Background technique [0002] In a wireless local area network, a station (STA) usually communicates with other stations or networks through an access point (AP). Even communication between two stations in the same Basic service set (BSS) requires Forwarding through the access point, that is, the sending station first sends the data to the access point, and then the access point forwards the data to the receiving station. In practical applications, when the distance between two stations is very short, which is suitable for direct link communication, if the data is forwarded through the access point, the communication efficiency of the system will be reduced. To this end, the Direct-link setup (DLS) mechanism is introduced. In the DLS mechanism, when two sites support the DLS function and one of ...

Problems solved by technology

[0003] However, it is found in practice that when two sites are suitable for direct link communication, if one of the sites does not support the DLS function, then the DLS mechanism cannot establish a direct link communication between the two sites
