PURPOSE: A system for supplying a service which announces a changed telephone number by using a short message of a terminal is provided to receive a changed telephone number by using a short message if a signal is transmitted through a terminal during a call forwarding process, thereby realizing user convenience without separately recording or storing the telephone number. CONSTITUTION: A terminal(10) receives a short message to display the short message. An announcement server(20) receives a telephone number transmitted from the terminal(10), and processes the received telephone number. A changed telephone number DB(30) stores information on an announcement of a changed telephone number. A retrieving module(40) compares the changed telephone number DB(30) with the telephone number to decide whether the number is changed, and informs the announcement server(20) of the results. A call forwarding module(50) forwards a call with the changed telephone number. An announcement module(60) announces the changed telephone number by using the short message. |
