摘要： A method for managing radio resource of a femto cell includes: providing, by the femto cell, a service to one or more UEs by using most of pre-set radio resource; receiving measurement results from the one or more UEs; determining whether or not one or more neighbor femto cells are closely located nearby based on the measurement results; and if it is determined that neighbor femto cells are closely located nearby, reducing the pre-set radio resource into a small radio resource and providing a service with the small radio resource.
