PURPOSE: A random access control method for effectively sensing a cooperative spectrum in a recognition wireless based frequency resource sharing system is provided to effectively detect a signal of a user terminal.;CONSTITUTION: A sensing node senses a spectrum in order to detect a signal for a user terminal(S101). The sensing node calculates area detection statistic rates based on a spectrum sensing result(S102). The sensing node calculates transmission rates based on the calculated area detection static rates(S104). The sensing node transmits sensing information to a fusion center based on the calculated transmission rates(S106). The fusion center determines whether a signal for the user terminal is existed based on the transmitted sensing information.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Start; (S101) Executing spectrum sensing in each node and calculating local test statistics and transmission probability P_k; (S102) Transmitting local test statistics as transmission probability P_k by each sensing node; (S103) Does one node transmit?; (S104) Accumulating each local test statistic and calculating the whole test statistic T; (S106) Maintaining transmission when a primary user is not existed; (S107) Determining the existence of a primary user
