System for controlling communications in a network based on a previous place name and relocated place name displayed on terminals of current conversation participants

摘要

A communication system is arranged to efficiently control communications as being conscious of location information of a mobile body. The communication system includes an address list managing unit, a data supplying unit, a call connecting unit, a display unit, and a user interface. The address list managing unit stores and manages an address list about the location of each registered member. The data supplying unit generates data based on the address list so that the data can be disclosed on a Web site. The call connecting unit gives a call to a destination member specified by a user side for controlling a call connection. The display unit displays a screen image of the data to be referenced on the Web site. The user interface is used for specifying a destination member and a communication service type on the screen.
