BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system and method for providing a call background sound service, and more particularly, to a call during a voice call using a conference call function provided by an exchange in a communication network such as a public switched telephone network (PSTN), a mobile communication network, and an internet network. The present invention relates to a method and a system for providing a call back tone service at the request of a caller or a called party.

In general, the call background sound service refers to an additional service that a caller or a receiver who is a caller can hear various background sounds while talking on a call terminal such as a general telephone, a mobile phone, and other mobile communication terminals.

Hereinafter, a conventional background voice service providing system will be described with reference to FIG. 1.

1 is a diagram illustrating a conventional call background sound service providing system.

Conventional call back tone service providing system is the originating terminal (1), terminating terminal (2), originating exchange (3), terminating exchange (4), location register (HLR: Home Location Register) (5), relay exchange (6) And a call background sound providing device 7.

Hereinafter, a method of providing a corresponding call background tone service in the conventional call background tone service providing system configured as described above will be described with reference to FIGS. 2 and 3.

2 is a flowchart illustrating a conventional call background tone service providing procedure, and FIG. 3 is a flowchart illustrating a conventional call background tone service providing method.

The caller who is the subscriber of the call background tone service inputs a special number specially designated in order to receive the call background tone service to the calling terminal 1, and the calling terminal 1 sends the call background tone request call to the calling exchange 3 (S101). ). For example, if you want to make a background tone call with the called terminal 2 with the telephone number 010-1234-5678, you must call * 79, which is the call background tone service identifier number, in front of the telephone number, such as * 7901012345678. .

Accordingly, the originating exchange 3 requests the location register 5 for the location information of the called exchange 4 interworking with the called terminal 2 of the called party (S102).

Accordingly, when it is confirmed that the call back tone service identifier number * 79 is attached to the outgoing call number, the location register 5 connects the outgoing voice call to the call back tone providing device 7 so as to route the corresponding call back tone. The address of the providing device 7 is returned to the originating exchange 3 (S103).

Accordingly, the originating exchange 3 performs ISUP (ISDN User Part) connection to the relay exchange 6 to confirm the address of the call background sound providing device and to connect the voice call to the call background sound providing device 7. (S104). Here, the reason why the relay exchange 6 is required is that if the call background sound providing device 7 is connected to all exchanges, the number of voice paths is required as much as the number of exchanges to be connected, so that the corresponding relay exchange 6 plays a role of channel integration. To do this.

In addition, the relay switch 6 performs voice call connection through ISUP signaling to the apparatus for providing a call background sound (S105).

Accordingly, the apparatus for providing a call background sound 7 checks an internal database to check whether the caller is a subscriber to a call background sound service, and if so, prepares a pre-selected call background sound source (S106).

Then, the call background sound providing apparatus 7 sets itself as a new call to which the call destination sound request is received and the originating terminal 2 is called to relay the call background sound request call received to the caller. The request call is requested to the relay switch 6 (S107).

Accordingly, the relay switch 6 requests location information of the called terminal 2 to the location register 5 to complete the call setup request call (S108).

Accordingly, the location register 5 requests an address for setting a call to the destination exchange 4 to which the destination terminal 2 cooperates according to the value of the internal subscriber location information database (S109).

Accordingly, the destination exchange 4 transmits its address for setting the call path to the location register 5 (S110).

Thus, the location register 5 returns the destination exchange address to the relay exchange 6 in response to the location information request (S111).

Then, the relay switch 6 connects the call setting request call of the call background sound providing device 7 to the corresponding destination switch 4 according to the destination exchange address to set the call path (S112).

Accordingly, the destination exchange 4 paging to the destination terminal 2 after the connection from the relay exchange 6 to the end (S113). . Finally, the voice call for the call background tone service includes the calling terminal (1)-> outgoing exchange (3)-> relay exchange (6)-> call background sound providing device (7)-> relay exchange (6)-> called exchange. (4)-> called terminal (2). When all the calls are connected in response to the called party, the call background sound providing device 7 mixes the prepared background sound into a voice call so that both callers, that is, the caller and the called party, hear the call background sound. Provided to the calling terminal 1 and the called terminal 2 along the connected voice call path (S114).

As described above, in the conventional method for providing a background voice service, only the caller can start the background phone call, and use a specially designated calling method such as using a special identifier number to indicate that the background phone call is used, and all the corresponding calls are made by the calling exchange. The call path must be established by connecting to the call background sound providing device, and even in the position of the call background sound providing device, audio mixing is performed while managing inbound calls with new outbound calls. There is a problem.

In order to solve the above problems, an object of the present invention is to request a caller or called party who is a caller during a voice call by using a conference call function provided by an exchange in a communication network such as a public telecommunication network, a mobile communication network, and an internet network.
