In addition, the background sound information storage unit 36 may be implemented as a database or as a separate file server.

Next, the operation of the background sound providing system having the above-described configuration will be described.

First, the user accesses the web server 39 through the Internet to receive the background sound providing service, and then sets personal information such as his / her calling number and name and a background sound environment to be provided (ST1). In this case, the user provides the initial background sound type, the background sound volume level, the background sound providing method, and the background sound ranking information to the web server 39, and the web server 39 stores the background sound information through the background sound processor 37. It is stored in the unit 36.

In the above state, the caller makes a call connection request with the background sound providing apparatus 30 through the corresponding communication network 20 through his communication terminal 10 in order to receive the background sound service (ST2).

Thereafter, the background sound providing apparatus 30 detects the called party information based on the call connection request information of the caller provided through the communication network 20 (ST2). That is, when predetermined call connection request information is applied to the background sound providing device 30 from the caller's communication terminal, the call connection request information is provided to the information detection unit 35 under the control of the call control unit 32, and the information detection unit ( 35 detects the caller's calling number and caller name information from the call connection request information and provides it to the call controller 32. The call control unit 32 allocates a communication channel to the caller's communication terminal, and controls the call control unit 32 to communicate with the ARS processing unit 34 through the communication channel. Here, the ARS processing unit 34 requests the caller's communication terminal to set the called number and the background sound service, and the information that is authorized from the caller's communication terminal is provided to the call control unit 32. The call controller 32 makes a call connection request to the called number provided from the ARS processor 34, and allocates a communication channel to the called number to perform call processing between the called number and the calling number.

In addition, the call control unit 32 performs the step ST2, and provides the background sound processor 37 with the calling number applied from the information detection unit 35. Then, the background sound processor 37 reads out the background sound information corresponding to the calling number received from the call controller 32 in the background sound information storage unit 36 (ST3). At this time, the user can change the background sound setting during the communication with the ARS processing unit 34 in step ST2, in which case the background sound change information is transmitted to the background sound processing unit 37 to update the background sound information storage unit 36. The background sound information is read out based on the updated information.

Thereafter, the call control unit 32 synthesizes the background sound read in the step ST3 to the voice signals of the caller and the called party, and performs call relay processing between the calling number and the called number through the switching unit 33 (ST5). That is, the call control unit 32 selects the background sound based on the background sound information set for the calling number through the background sound processing unit 37 and adjusts the volume to provide the audio sound to the audio mixer 38. In addition, the call control unit 32 provides the audio mixer 38 with a voice signal applied through a communication channel of the calling number and the called number.

That is, the keypad of the communication terminal (not shown) to change the background sound environment such as adjusting the volume of the background sound set by the caller or changing the type of background sound while the background sound service between the caller and the called party is provided. When a predetermined key is pressed in advance, the key input signal is applied to the background sound providing device 30 together with the caller's voice signal. The caller's voice signal is provided to the information detector 35, and the information detector 35 detects a specific key input signal, that is, a DTMF signal, from the caller's voice signal (ST6). Subsequently, the information detector 35 transmits the detected DTMF signal to the background sound processor 37, and the background sound processor 37 updates the background sound information storage unit 36 based on the detected DTMF signal (ST7). In addition, the information detector 35 changes the background sound to correspond to the updated background sound information, and provides the changed background sound to the called party and the caller by providing the changed sound to the audio mixer 38.

For example, when a DTMF signal corresponding to "5 *" is applied from the caller communication terminal while the background sound service is provided to the caller and the called party, the background sound information storage unit 36 is updated so that the background sound volume level corresponds to "5" and the background sound control is performed. Through the portion 37b, the current background sound level is changed and provided. In addition, when a DTMF signal corresponding to "3 #" is applied from the caller communication terminal, the background sound providing device 30 stops the currently provided background sound, and reads the background sound of the third rank in the background sound information storage unit 36 to send the caller. And to the called party. In addition, when a DTMF signal corresponding to "* 2 #" is applied from the caller communication terminal, the background sound providing apparatus 30 changes the background sound providing method so as to repeatedly provide the background sound currently being transmitted.

Thereafter, when the call connection between the caller and the called party is terminated (ST9), the background sound providing apparatus 30 performs call connection termination processing such as recovering the communication channel assigned to the caller and the called party (ST10).

That is, according to the above embodiment, the setting of the background sound type, the background sound volume level, the background sound providing method, etc., can be made for the background sound that the caller is arbitrarily provided to while still providing the background sound service to the caller and the called party.

Therefore, the user can always be provided with a background sound service suitable for the call environment whenever the call with the other party.

In addition, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the technical spirit of the present invention.

As described above, according to the present invention, the user can change the type of the background sound, the background sound volume level, the background sound providing method, and the like for the background sound that the caller is randomly provided to while the background sound service is provided to the caller and the receiver. It is always possible to receive a background sound service suitable for the current call environment.
