ABSTRACT:
To make a call, a calling-end terminal station (3) notifies a call-up control unit (71) of a communications network (7) of the terminal station number of a called-end terminal station (5) so as to cause it to stand by for a connection. The calling-end terminal station (3) notifies a calling party information server (9) of the calling-end-terminal-station number and the called-end-terminal-station number and instructs it to transmit to the called-end terminal station (5) calling party information stored in advance for the caller and called parties. The calling party information server (9) transmits the calling party information to the called-end terminal station (5) which in turn instructs the call-up control unit (71) to exit standby mode. This amounts to the communications network (7) calling up the called-end terminal station (5), resulting in the called-end terminal station (5) reproducing the received calling party information to alert the user to the call from the calling-end terminal station (3). If the user accepts the call, voice communication is started between the calling-end terminal station (3) and the called-end terminal station (5). A communications system is thereby realized whereby alert data to alert to a call can be altered according to the calling party with no settings at the called end.
