PURPOSE: A method for searching destination codes at a minimum in an MSC(Mobile Station Controller) is provided to reduce the load of call processing and to improve the performance of a system by minimizing the comparison frequency between an inputted destination code and registered destination codes. CONSTITUTION: An MSC calls a statistical library(ST11) and judges whether the statistical library is the first statistical event(ST12). If the statistical library is the first statistical event, the MSC compares an inputted destination code with a registered destination code and obtains a destination code index(ST13). The MSC stores the obtained destination code index in a call register(ST14) and records the first statistical event(ST15). However, in case that it is judged that the statistical library is not the first statistical event, the MSC checks whether a destination code index equivalent to an relevant call register value is positive(ST16). If the destination code index is positive, the MSC records the destination code statistical event in an area corresponding to the destination code index(ST17). Then the MSC records the outgoing call statistical event(ST18).
