Abstract
Whenever there is an incoming call to a terminal accommodated by a terminating exchange, the terminating exchange creates incoming-call data, which contains at least the terminating subscriber's number, the originating subscriber's number and the communication time, and transmits the incoming-call basic data to a communication center. The communication center accumulates the incoming-call basic data and, in response to issuance of an output request, creates and outputs an incoming-call logging list for the requesting user on the basis of the incoming-call basic data. Further, secondary data, which includes at least the names and addresses of calling parties, is registered in a data base beforehand in correspondence with subscriber's numbers. The secondary data is combined with the incoming-call basic data to create incoming-call information, which is then stored in memory. In response to issuance of the output request, the incoming-call logging list of the requesting user is outputted based upon the incoming-call information.
