摘要

PURPOSE: A mobile communication server for automatically changing a telephone number stored in a terminal, a method thereof, a short message transmission server and a method thereof are provided to enable a called terminal to confirm the second number of a calling terminal in a ring back tone state. CONSTITUTION: A database(202) stores the first number, that is, a phone number of a calling terminal before the change and the second number, that is, a phone number after the change. A communication module(204) receives a call connection request signal to the called terminal through an exchange from the calling terminal having the second number. When the communication module receives the call connection request signal, a data transmitter(210) transfers the first number and the second number stored in the database to the called terminal. The called terminal displays the name of a caller and automatically changes the first number into the second number.
