A cellular mobile telephone apparatus has circuits for generating messages, a storage circuit for storing messages, and transmitter/receiver circuit for transmitting a message. When the user of the cellular mobile telephone apparatus cannot immediately respond to an incoming call, a desired one of a plurality of previously generated and stored messages can be transmitted to a calling party through simple key manipulations or by other means.

According the present invention, a line using status of each personal station which contains an existing analog line in a route between the personal station and an exchange unit is determined. The PS number of a personal station having a telephone call, the line number used for the telephone call, and the line use order of in which the personal station uses the line are registered in a billing unit provided to a cell station every time a telephone call is made, and the line number, the line use order and the charging rate parameter of usage of the line are registered in a billing center every time a telephone call is made. Further, the information registered in the billing unit is periodically collected in the form of analog signals in the billing center, and the PS number and the charging rate parameter are associated with each other by using the line number and the line use order as a key.
