Problems solved by technology

[0006] However, since the establishment process of the direct link between two WIFI terminals in the prior art needs to depend on the APs currently associated with the two WIFI terminals, and requires that the two WIFI terminals establishing the direct link be associated with the same AP at the same time, therefore , when there is no AP associated with the two WIFI terminals or there is no AP in the surrounding environment, the two WIFI terminals cannot establish a direct link

Embodiment approach

[0065] As an implementation manner, the first STA device 51 may also include:

[0066] The switching unit is configured to switch the UMTS link to the established direct link by using the heterogeneous network switching mechanism in the IEEE802.11 standard as required after establishing the direct link through WIFI.

[0067] implemented as Figure 5 The first embodiment of the communication system of the present invention shown, by establishing the UMTS link between two dual-mode mobile communication terminals (the first STA device 51, the second STA device 52), and using the UMTS link on the UMTS link Exchanging direct connection establishment messages for negotiating and confirming the parameters for establishing a direct connection link using WIFI, and establishing the direct connection link using the WIFI according to the parameters confirmed through negotiation, thereby solving the problem when there are no two dual-mode mobile When the AP associated with the communicati...

Abstract

The embodiment of the invention discloses an establishment method of a direct connected link, comprising the following steps: utilizing a first type wireless media to interact with direct connected establishment information; wherein the direct connected establishment information is used for consulting and confirming parameters utilizing a second type wireless media to establish the direct connected link; and utilizing the second type wireless media to establish the direct connected link according to the consulting and confirmed parameters. The embodiment of the invention also discloses a station device and a communication system. When the embodiment of the invention is adopted, two WIFI terminals can still utilize WIFI to establish the direct connected link when an AP associated with the two WIFI terminals does not exist or the AP does not exist in the surrounding environment.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for establishing a direct link, a station device and a communication system. Background technique [0002] The Institute of Electrical and Electronics Engineers (Institute of Electrical and Electronics Engineers, IEEE) 802.11z standard is to study two wireless fidelity (Wireless Fidelity, WIFI) terminals (that is, station equipment) connected to the same access point (Access Point, AP). , STATION, referred to as STA) exchange messages through the data channel provided by the AP, so as to establish a direct link mechanism, such as figure 1 As shown, because the messages exchanged during the establishment of the direct link between two WIFI terminals are encapsulated in the data frames transmitted by the two WIFI terminals through the data channel of the AP, so the establishment process of such a direct link It is also called Tunneled Direct Link Setup (TDLS). According to the ...
