A radio communication system capable of preventing interference in the existing microwave transmission systems with a simple construction. In a radio communication system for communicating between a first and a second communication terminal equipments by using the frequency band of the existing microwave transmission systems, judging whether the first communication terminal equipment is within a communicable area is performed based on information specifying the position of a base station of other radio communication system which is obtained therefrom, and if within a communicable area, it shifts to a transmittable state and transmits a registration message to the second communication terminal equipment to be shifted to a transmittable state. Thereby, interference in the existing microwave transmission systems can be prevented with a simple construction without adding a circuit for confirming the present position as a prior art.
