Abstract: The present invention relates to a radio resource reallocation method based on the circuit mode. In order to efficiently use the radio resource in the packet-based data transmission system, a circuit mode radio resource is reallocated based on a rearrangement information element and a rearrangement counter information element by using the circuit mode. Accordingly, an unused region of the discontinuous radio resource that can be generated by resource de-allocation and resource change can be eliminated, and a resource allocation mismatch that can be generated by a MAP receiving error can be solved.

Abstract: A method of setting a cycle of a low-duty mode in a femto base station is provided. The cycle of the low-duty mode has a pattern in which an available interval and an unavailable interval repeatedly appear, and the available interval is set to include a paging listening interval of a paging cycle. A method of setting a cycle of a low-duty mode in a femto base station having a service area overlapping with that of a macrocell is provided. An unavailable interval is set by taking the overlapping degree of the service area of the femto base station with the macrocell into consideration. A method of setting a cycle of a low-duty mode in a plurality of femto base stations operated in the low-duty mode is provided. The same cycle can be set for a plurality of base stations.
