摘要

A scheme is disclosed wherein use of an information signal processing function of a telephone communication terminal can be limited taking regulations applied to the other party of communication or a will of the other party of communication into consideration. A base station which repeats a radio wave of a call originating portable telephone terminal transmits a country code thereof to an object call terminating telephone terminal. Based on a region identification code such as a state code (international number) or a country code included in information received upon termination of the call, the call terminating terminal refers to a status table prepared 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 and, where such restrictions are applied, contents of the limitations. In accordance with the specified limitation contents, use of the conversation recording function during communication is controlled such that a warning sound generator is controlled to transmit warning sound or a voice decoding section is controlled to disable recording of conversation into a memory.
