Besides a plurality of base stations (64) enabling telephone calls between mobile terminals (30) and between the mobile terminals (30) and fixed telephones (12), a call management apparatus (60) is further provided a broadcasting station (72) that transmits call origination information via a broadcasting station carrier of a frequency band that is lower than that of a telephone call carrier. Furthermore, each mobile terminal (30) is provided with a broadcasting station carrier receiver portion capable of receiving broadcasting station carriers. An exchange control station (70) transmits call origination information from the broadcasting station (72) via a broadcasting station carrier if a mobile terminal (30) is in a state in which it is incapable of transmission/reception via the telephone call carrier. Since broadcasting station carriers have a better electromagnetic reflection characteristic than telephone call carriers, each mobile terminal (30) can receive call origination information by using the broadcasting station carrier receiver portion even if the mobile terminal (30) is in a state in which it is incapable of transmission/reception via the telephone call carrier. Thus, the communication of call origination information to the mobile terminals (30) can be improved.
