Patent ID: 8855566

Claim:
A method for managing radio resources of a base station, the method comprising: evaluating a radio environment between the base station and at least one neighboring base station or a radio environment between the base station and terminals connected to the base station; when the evaluated radio environment does not meet predetermined criteria, selecting a new radio resource; and deactivating the existing radio resource and activating the new radio resource, wherein deactivating the existing radio resource and activating the new radio resource comprises releasing the existing radio resource and increasing a power of the new radio resource gradually in predetermined increments after the existing radio resource is released, or decreasing a power of the existing radio resource gradually in predetermined decrements to release the existing radio resource after the new radio resource is activated, wherein each of the existing radio resource and the new radio resource include a preamble index, and wherein, when a plurality of terminals is in an idle state, increasing the power of the new radio resource gradually includes: transmitting a paging message to the plurality of terminals at a power of a first level, increasing the power from the first level to a second level when only at least one first terminal succeeds in network connection from among the plurality of terminals, and transmitting the paging message to remaining terminals at the power of the second level, and increasing the power from the second level to a third level when at least one second terminal fails in network connection from among the remaining terminals, and transmitting the paging message to the second terminal at the power of the third level.
