Portable telephone terminal device and portable telephone system using the same

Abstract

For reporting an emergency at a minimal level if a user enters the emergency and requires a help of a third party, a portable telephone terminal device receives reported information “S1” constantly transmitted from a radio base station in a country and a district in which the user is roaming, and obtains basic information for use in the communications with the radio base station. The portable telephone terminal device transmits the information about its own station to the radio base station to perform location registration “S2”. The portable telephone terminal device transmits contract area identification information “S3”, and reports corresponding function presence/absence information “S4”. The radio base station transmits to the portable telephone terminal device the information about emergency telephone numbers “S5” of the nearest medical facilities, or the like and formatted text “S6” in the local official language for use in reporting an emergency to the facilities, or the like in either voice or characters. The portable telephone terminal device receives the emergency telephone numbers “S5” and the formatted text “S6”, stores them in a storage unit, and enters a wait state.
