Method and system for identifying wireless mesh network

The invention discloses a method and a system for identifying a wireless mesh network. The method comprises the following steps: an MP node selects an identified node as a father node when a new node is accessed into the network and the node is a grid node MP node; a solely marked safe passage exists between the father node and AC; the MP node identifies by using the father node as an identification point; an identification message is transmitted to the AC through the safe passage between the father node and the AC and then transferred to AS by the AC; in the same way, a return message of the AS is transferred to the father node by the AC through the safe passage; the MP node is identified; the identification information is simultaneously stored on the AC so as to identify the MP node for the second time. By adopting the method and the system which are disclosed by the invention, the problem that the access delay is increased because the identification mode adopted in the prior art is fussy is solved.
