摘要： The present invention provides an MiAN, a system and a method for finding partners for use in an MiAN cluster system. The method comprises the step of performing, by the slave MiAN, search on working channels of the proximity interface in accordance with a preset search order, and trying to establish a communication connection with the proximity interface of a master MiAN with respect to the MiANs that have been searched during the search process. When selecting the working channels of the proximity interface, all the master MiANs in the clustering system perform search in accordance with the search order, and operate on the channel which has been searched first in accordance with the search order and the channel quality of which meets a predetermined requirement. According to the present invention, the processes of finding, selecting and binding partners in the MiAN cluster system will be accelerated.
