Method and system for switching off base stations within a cellular network by message passing

A method for determining whether the power of an individual base station in a cellular network is blocked by itself includes: receiving terminal messages in an error value from a terminal in a cell coverage of the base station in the cellular network; calculating the error value of the base station message on each terminal based on the received terminal messages; individually transmitting the base station messages of the calculated error value of each terminal; repeatedly performing the reception, the calculation, and the transmission until the calculated error value of the base station message is converged on a predetermined value; calculating a base station message convergence value, which is one error value on whole terminals based on the converged error values of the terminal messages when the error value of the base station message is converged; and determined whether the power of the base station is blocked based on the base station message convergence value.
