MOBILE COMMUNICATION SYSTEM, BASE STATION DEVICE, MOBILE STATION DEVICE, AND MOBILE COMMUNICATION METHOD

摘要

Even when a radio communication terminal is located at a cell edge in the multi-band mobile communication method, it is possible to stably execute cell search so as to easily establish a connection with a radio base station. The radio communication terminal includes: a first judgment unit (13) which judges whether a broadcast map can be received from a plurality of radio base stations; a second judgment unit (14) which judges whether an AAS diversity map can be received in the ascending order of the used frequency bands of the radio base stations when it is judged that the broadcast map cannot be received; and a communication control unit (15) which selects the radio base station which is judged to be capable of receiving the AAS diversity map as a radio base station of the connection destination and communicates with the selected radio base station.
