Function limiting method for telephone communication terminal, telephone communication method, telephone communication terminal and repeating center equipment

摘要

An information signal processing function of a telephone communication terminal can be limited taking regulations applied to the other party or an input of the other party into consideration. A base station that repeats a radio wave of a call originating portable telephone terminal transmits a country code thereof to a telephone terminal. Based on a region identification code such as a state code (international number) or a country code included in information received upon origination of the call, the called terminal refers to a status table in a ROM thereof to specify presence or absence of limitations to recording of conversation during communication applied to a state or a region in which the call originating terminal is used. In accordance with the specified limitation contents, use of the conversation recording function during communication is controlled such that a warning sound generator transmits warning sound or a voice decoding section disables recording of the conversation.
