The object of the present invention is to provide a cellular phone to be used for emergency reports that performs GPS positioning by means of remote control from an emergency report center, and transmits positional information to the emergency report center. The emergency report cellular phone according to the present invention is constituted such that when an emergency report switch thereof is depressed, a call request is made to the emergency report center. The emergency report center transmits a response signal with the result that a call link is formed between the emergency report cellular phone and the emergency report center. Following completion of the telephone call, the emergency report center transmits a position recalculation command message, by means of a DTMF signal. The emergency report cellular phone, which has received this command message, performs GPS positioning and then converts latitudinal and longitudinal information to a DTMF signal before transmitting same to the emergency report center. As a result, even in a case where, in a time of emergency, a reporting party is unable to perform GPS positioning manually as a result of a poor physical condition, for example, since GPS positioning is possible by means of remote control, it is possible to rescue the reporting party in a rapid and reliable manner.
