  • Communications system using portable recording medium
    Patent number: 6470082
    Abstract: By using an external portable recording medium (for instance, IC card) that stores a personal ID, a communications apparatus automatically transmits the personal ID and its own terminal identification information to a center apparatus. The center apparatus manages the personal ID and the terminal identification information so that they are correlated with each other. For example, the terminal identification information includes a called-party address, a communication mode, and a position ID. Further, the center apparatus manages a present/absent mode for each personal ID. During the present mode, the center apparatus forwards a call using a personal telecommunication number, such as a UPT (universal personal telecommunication) number, which corresponds to a certain personal ID to a communications apparatus that corresponds to the personal ID. During the absent mode, the center apparatus automatically records a message.
