Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of method for building up of direct connected link, a kind of station equipment and a kind of communication system.
Background technology
Institute of electrical and electronic engineers (Institute of Electrical and Electronics Engineers, IEEE) the 802.11z standard is that research is connected to same access point (Access Point, AP) two Wireless Fidelity (Wireless Fidelity on, WIFI) terminal (is station equipment, STATION, abbreviate STA as) between the data channel that provides by AP carry out interacting message, thereby set up the mechanism of direct connected link, as shown in Figure 1, because the interactive messages in the process set up of two WIFI terminal room direct connected links is to be encapsulated in the Frame of two WIFI terminals by the data channel transmission of AP to transmit, so the process of setting up of such direct connected link be called again the tunnel direct-connected set up pattern (Tunneled Direct Link Setup, TDLS).According to the TDLS mechanism that present IEEE802.11z standard provides, the foundation of two WIFI terminal room direct connected links must depend on the data channel of setting up by AP, and two WIFI terminals that require to set up direct connected link are associated with same AP.
About the foundation of direct connected link between two WIFI terminals, introduced two kinds of methods at present among the IEEE802.11:
One is the direct-connected request message of setting up that a WIFI terminal is set up direct connected link to AP transmission and the 2nd WIFI terminal of own current association, by this AP this direct-connected request message of setting up is resolved identification, and should direct-connectedly set up request message and further be forwarded to the 2nd WIFI terminal, the 2nd WIFI terminal will send to AP to the direct-connected response message of setting up of setting up request message, and by further being forwarded to a WIFI terminal after the AP parsing identification;
The 2nd, earlier by a WIFI terminal, the 2nd WIFI terminal is set up a data passage by AP, when WIFI terminal desire is set up direct connected link with the 2nd WIFI terminal, the one WIFI terminal sends the direct-connected request message (being packaged in the Frame) of setting up by the current described data channel of having set up to the 2nd WIFI terminal, directly the direct-connected request message of setting up is identified parsing by the 2nd WIFI terminal, and the direct-connected response message of setting up sent to a WIFI terminal by described data channel, receive that a direct-connected WIFI terminal of setting up response message sends the direct-connected acknowledge message of setting up by same mode to the 2nd WIFI terminal again, under this pattern, the direct-connected message of setting up of the one WIFI terminal and the 2nd WIFI terminal interaction is directly to transmit by the Frame encapsulation, so this pattern is also referred to as TDLS.
But because the direct connected link of two WIFI terminal rooms of prior art is set up the AP that process all needs to depend on the current association of two WIFI terminals, and two WIFI terminals that require to set up direct connected link are associated with same AP simultaneously, therefore, when there be not AP in the AP that does not have the association of two WIFI terminals or surrounding enviroment, two WIFI terminals just can't be set up direct connected link.
