PURPOSE: A method for supplying a background sound and a recording service is provided to connect the first speech path with the second speech path, and to mix background sounds previously prepared at the first and second speech paths, thereby supplying the background sounds while performing a voice call. CONSTITUTION: An originating MSC perceives a position of a receiving terminal through an HLR(301). The originating MSC transmits a call connection request signal to a receiving MSC(303). If a speech path is connected up to the receiving MSC, the receiving MSC transmits the call connection request signal to the receiving terminal(305), and transmits the request signal to a background sound supplying device(307). The receiving MSC transmits a call connection response signal(313). The background sound supplying device connects a speech path with the receiving terminal, and mixes a preset background sound with the speech path(315). An originating user calls a receiving terminal user with the background sound(317). |
