Abstract: A communication method according to an embodiment comprises: notifying, by a base station, a radio terminal of a discontinuous reception (DRX) cycle; notifying, by a Mobility Management Entity (MME), the radio terminal of an extended DRX cycle longer than the DRX cycle; determining, by the radio terminal, whether or not the base station supports an extend DRX; using, by the radio terminal, the extended DRX cycle to execute an extended DRX operation in an idle mode, in response to determining that the base station supports the extend DRX; and using, by the radio terminal, the DRX cycle to execute a DRX operation without using the extended DRX cycle, in response to determining that the base station does not support the extend DRX.

Abstract: A control method comprises: transmitting, by a first management apparatus included in a first network allocated with a first frequency band, to a second network allocated with a second frequency band, an allocation request signal for requesting allocation of a part of the second frequency band to the first network, the signal being generated on the basis of a usage state of the first frequency band, determining, by a second management apparatus included in the second network, on the basis of a usage state of the second frequency band, a bandwidth to be allocated to the first network out of the second frequency band and an allocated frequency band corresponding to the bandwidth; managing the allocated frequency band as unavailable; transmitting, an allocation request response signal including information indicating the allocated frequency band, to the first network; and managing the allocated frequency band as available in the first network.
