Whether channel codes corresponding to the number of requested channel codes exist in an i-th index scrambling code is searched(S203). If exist, the vacant channel codes are allocated to a corresponding mobile station of the arrived call(S204). If channel codes corresponding to the number of requested channel codes do not exist in the i-th index scrambling code in the S203 step, the index i is raised by one step to i+1(S205).
