Cognitive communication network system and communicating method thereof

Abstract

Object: To provide a mechanism and a function of a system that can determine a communication method and the like effectively utilizing frequency resources, considering priority of each communication, in a cognitive communication network system of a frequency shared type or the like assuming that a given frequency band is shared by a plurality of systems in use. Solution: In a configuration in which a cognitive communication network system has a plurality of radio access networksand a superior communication networkthat provides a common platform at least to the radio access networks, in a plurality of base stationson at least a part of the radio access network, base-station state obtaining meansthat collect information relating to a state of the base station itself in the base station or a communication state and base-station communication reconfiguration managing meansthat reconfigure at least one of either a selection of the base station to be used in the communication or a communication condition in the base station on the basis of the information collected by the base-station state obtaining means are provided.
