Method, system and device for dynamically determining Off-Channel

Abstract

The invention discloses a method for dynamically confirming Off-Channel, which comprises the following steps: wireless environment and channel parameters of a local terminal and a receiving terminal are obtained by a sending terminal; the sending terminal sends out a request message, so as to switch to the receiving terminal, and the request message for switching carries an information list of a switching channel; the sending terminal receives the switching response message returned by the receiving terminal, and the response message carries the switching channel information confirmed by the receiving terminal. The invention further discloses a system and equipment for dynamically confirming the Off-Channel. The invention ensures that the Off-Channel which is available through direct connection is confirmed on a dynamic and real-time basis, so that the availability of Off-Channel is ensured.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, system and device for dynamically determining an Off-Channel. Background technique [0002] In the prior art, two WIFI (Wireless Fidelity, wireless fidelity) terminals connected to the same AP (Access Point, access point) exchange messages through the data channel provided by the AP, thereby establishing a direct connection channel, because The messages exchanged during the establishment of the direct channel between the two terminals are encapsulated in the data frames transmitted by the two terminals through the communication channel of the AP. Therefore, such a direct channel establishment process is also called TDLS (Tunneled Direct Link Setup , tunnel direct connection establishment mode). According to the TDLS mechanism provided by the current standard, the establishment of a direct connection channel between two WIFI terminals must depend on the A...

AI Technical Summary

Problems solved by technology

Because, after the direct connection channel of two WIFI terminals is established, the communication path will not necessarily be switched from the AP path to the direct connection path immediately, and even if the direct connection path is switched to the direct connection path, the Off-Channel may not be used (the Base-channel may also be used ), so that due to time or changes in the wireless environment, the pre-determined Off-Channel will become unavailable when the terminal needs to switch from Base-channel to Off-Channel (for example, the same frequency as Off-channel appears nearby during the period) sources of interference)
