Abstract:
1. A wireless communication network having a plurality of base stations for forming a cellular system for wireless communications with a plurality of mobile terminals via uplinks and downlinks, said wireless communication network comprising: a downlink dedicated channel transmission unit configured to individually transmit communication data from the plurality of base stations to the plurality of mobile terminals using downlink dedicated channels of the cellular system; an uplink dedicated channel reception unit configured to individually receive communication data from the plurality of mobile terminals using uplink dedicated channels of the cellular system; a downlink common channel transmission unit configured to transmit broadcast information from the plurality of base stations to the plurality of mobile terminals using the downlink common channels of the cellular system; a broadcast information input unit configured to input high priority broadcast information as the broadcast information; and a transmission method changing unit configured to change the transmission method of the downlink common channels used by the downlink common channel transmission unit so as to make effective radiation power of the downlink common channels of the base stations large at places in the coverage of each of the base stations subjected to propagation loss when the high priority broadcast information is input.
