Abstract:
1. A method for managing a pre-set radio resource of a femto cell, the method comprising: providing a service to one or more user equipments (UEs) by using a portion of the preset radio resource; receiving measurement results from the one or more UEs; determining whether one or more neighbor femto cells are located nearby based on the measurement results; reducing the pre-set radio resource to a small radio resource and providing the service with the small radio resource if it is determined that one or more neighbor femto cells are located nearby; and increasing the small radio resource to the pre-set radio resource to provide the service if interference with the one or more nearby neighbor femto cells is reduced, wherein increasing the small radio resource comprises: determining whether there are UEs that have been connected for more than a pre-set time period in the femto cell; and providing a service to a UE among the UEs that have been connected for more than the pre-set time period whose signal-to-noise interference noise ratio (SINR) does not increase or decrease in excess of a threshold value by using the entire pre-set radio resource.
