Hereinafter, a description will be given of the functions and procedures performed in the respective component blocks for the call tone service of the present invention with reference to FIG. 2.

When the caller attempts to make a call, the calling terminal 110 transmits the called party's telephone number to the calling switching center 120 to request a call line setting.

Before the call line is established, the originating switching center 120 confirms the current location information of the called party and whether the call tone service is registered according to the present invention through the HLR 122 (S201).

At this time, when the called party is a registrant of the ring tone service, the SSP of the originating exchange 120 switches to the intelligent network system without directly connecting to the called exchange 125, thereby converting the identified recipient's location information and the ring tone service registration information into the intelligent network SCP. (S202).

Accordingly, the SCP 123 confirms that the intelligent network call is the call tone service call of the present invention and transmits the calling party and the called party information received from the SSP of the originating exchange 120 to the IP 124 of the intelligent network. (S203) IP 124 transmits the caller information and the called party information (service registration information, identification information, etc.) to the service management server 130 (S204).

Accordingly, the service management server 130 checks the call ring tone content set by the called party, and reads it from the sound source DB 135 until the call is made with the called party. In place of the ring-back tone to (110) (S205).

On the other hand, the IP 124, while the call connection sound is transmitted to the calling terminal 110 in this way, connected to the corresponding destination exchange 125 through the location information of the called terminal received from the calling exchange 120 and the called terminal Paging 115 is performed. (S206)

When the called party paged through the destination exchange responds to the call, the IP 124 disconnects the ring back tone flowing out to the calling terminal (S207). The service management server 130 calls the caller's background sound of the called party. In step S208, the IP 124 performs the conference call function of the switching center CMX to the call management line 130 for the call line between the caller and the called party. By adding a line with), the background sound of the call can be transmitted while maintaining a smooth call between the caller and the called party. (S209)

In addition, while the call connection sound or the call background sound is being transmitted in this way, the service management server 130 changes the sound source or the volume of the call background sound being transmitted according to the caller or caller's DTMF signal or the menu window operation of the terminal. You can control the adjustment, interruption / resume of the sound source, and so on.

The call background tone service may be provided to the calling party and the called party immediately after the call connection sound is blocked, and may also be provided by the called party's request (DTMF). This depends on the initial setup of the called party.

On the other hand, Figure 3 is a more detailed block diagram of the service management server 130.

As shown in FIG. 3, the service management server 130 may include an interface unit 131, an authentication unit 132, a sound source setting unit 133, a sound source output unit 134, a control unit 136, and a transmission / reception unit. 137, voice modulator 138, and the like.

Here, the interface unit 131 is in charge of a connection interface with an external network PSTN, wired, wireless Internet network, IP (124) of the intelligent network, and the authentication unit 132 confirms the forwarded recipient information It authenticates whether the called party is a subscriber to the ring tone service of the present invention.

In addition, the sound source setting unit 133 provides various call connection sound or call background sound contents stored in the sound source DB 135 and sets and manages the call connection sound or background sound of each subscriber by the user's selection. In addition, it is possible to query / listen or edit (or record a voice message) of a preset call connection sound or background sound and provide an appropriate user interface accordingly. The sound source setting may be provided through ARS, wired or wireless Internet, and for this purpose, the sound source setting unit 133 should have an appropriate user setting interface for each.

In addition, when the sound source output unit 134 is authenticated as a subscriber through the authentication unit 132, the received caller information is checked and the preset call connection sound and the call background sound of the called party are read from the sound source DB 135. It is sent to the caller or called party.

The voice modulator 138 modulates the subscriber's voice and, in conjunction with the voice setter 133, performs voice subscriber recording and voice call editing.

In addition, the transmitting / receiving unit 137 is responsible for data transmission and reception with the external network and the intelligent network IP 124, and converts into a communication protocol of each network to transmit / receive data and to make a call sound to a calling or receiving terminal. Data transmission, DTMF signal for controlling the sound source, the setting control signal when setting the ARS through the PSTN, and the sound source setting control signal through the Internet from the sender or the receiver.

At this time, the receiver checks whether the called party is a subscriber of the call tone service of the present invention, and performs a general call processing process if the subscriber is not a service subscriber (S403).

On the other hand, when the called party is a service registrant, the SSP of the outgoing exchange 120 switches to the SCP 123 of the intelligent network without directly connecting to the destination exchange 125, and the intelligent network call from the SCP 123 is the call tone of the present invention. After confirming the service call, the caller information, the confirmed caller's location and service registration information are transmitted to the intelligent network IP 124. (S404)

Accordingly, the IP 124 transmits the caller and the called party information to the service management server 130, and the service management server 130 reads the call connection tone of the called party from the sound source DB 135 and the call exchanger. Send to the sender side through (S405).

In addition, the IP 124 confirms the corresponding destination exchange 125 through the called party location information, and Paing the called party through the destination exchange (S406).

At this time, if there is no answer of the called party, the ring back tone is continuously transmitted to the caller, and if there is no response even after a predetermined time elapses, the call ends.

On the other hand, if there is a response from the called party, the IP 124 cuts off the call connection sound of the caller and performs a conference call function, thereby establishing a call line between the calling terminal and the called terminal from the service management server 130. The background sound of the call is transmitted to both the caller and the called party. (S408)

On the other hand, while the call background sound flows out, the caller or the called party can request control of replacement of the sound source, interruption / resume of the sound source, volume control, etc. through the operation of the DTMF signal or the menu window.
