Description

Bidirectional Sound Effect Service System and Method During Conversation in Telecommunication Network

The present invention relates to a system and method for transmitting a sound effect during a call. More particularly, the present invention relates to a system for performing a sound effect service when a call is set up between a calling terminal and a called terminal. The present invention relates to a system and method for transmitting a two-way effect sound during a call to transmit a corresponding sound effect to a calling terminal and a called terminal to transmit various sound effects during a call.

The existing telephone service does not implement a service that plays an intended sound effect other than voice by a subscriber's operation during a voice call to the other party.

As a similar function of the existing technology, an emoticon in an Internet messenger service is exemplified. An emoticon is a pictogram representing various emotion expressions. The emoticon expresses one's emotions to the other while expressing each other's intentions through the characters.

However, the above emoticon of the messenger is merely applied to the text conversation, but not to the voice conversation.

On the other hand, in the telephone service, a background sound call service is proposed, which is a technology in which a user sets a background sound in advance and plays it at the start of a call. The background sound is unilaterally played by the caller and the receiver cannot play the background sound. That is, bidirectional service is not possible.

In addition, in the related art, a prank call elimination service is proposed to transmit a strange sound effect to a counterpart when it is determined to be a prank call, which is limited to a specific purpose and is implemented as a function of a telephone terminal rather than a function of a network. In order to do so, it was necessary to purchase a phone that provides the above functions.

In addition, the ring back tone service that transmits a predetermined sound source to a caller and a caller in a call waiting is a service that statically transmits only a predetermined sound source only in a call waiting state. The disadvantage was that it could not transmit various sound sources dynamically and in real time.

Accordingly, the present invention is to solve the above disadvantages and problems of the prior art, so that the user of the call service of the wired and wireless networks or mobile communication networks can express their intention using not only simple voice calls but also sound effects. Accordingly, an object of the present invention is to provide a system and method for transmitting a two-way effect sound during a call to provide an entertainment function in a telephone communication.

On the other hand, when a call is established between the calling side exchange 30 and the called side exchange 31 via the sound effect server 210 as described above, when the call is connected, the sound effect server 210 is the caller and the called party is busy Recognizing the DTMF signals transmitted from the calling side exchange 30 and the called side exchange 31 according to the pressing of a specific button, the caller sends the sound source according to the effect sound code information for each address number set in the DB server 220 for each subscriber. And it transmits to the calling terminal 100 and the called terminal 110 with the called party's voice signal.

Call setting process and sound effect sending process of the two-way effect sound transmission service system of the present invention configured as described above will be described below with reference to FIGS.

First, FIG. 2 is a flowchart illustrating a call setup process of the two-way effect sound transmission service method during a call according to the first embodiment of the present invention, and shows a call setup process when the caller is an effect sound service subscriber.

As shown, first, as the number of the called terminal is input from the calling terminal and the call is attempted (S101), the calling exchange requests the location information to the calling home location register (S102).

The calling party's home location register determines whether the caller who attempted the call subscribes to the sound effect service and the activation state of the service (S103), and if the user is a service user, includes the routing information to the sound effect server in the response message for the location information request. And transmits to the calling side exchange (S104), and the calling side exchange establishes a call path with the sound effect server according to the received routing information, connects a call (S105), and receives information to the sound effect server (MIN). Number).

Next, the sound effect server requests a relay call processing by using the incoming information received from the originating exchange to a gateway exchange (cellular gateway system (CGS) or an adjacent exchange) connected thereto (S106), and the gateway exchange receives the incoming call. The location information of the called party is requested to the side home location register (S107), and the called home location register requests routing information to the called side exchange (S108).

The called party home location register receives a response message for a routing information request from the called party exchange (S109) and transmits a response message for the location information request to the gateway exchange (S110), wherein the gateway exchange uses the relay. A call path is established between the sound effect server requesting the call processing and the called side exchange (S111).

Accordingly, the calling exchange and the called exchange provide a call path between the calling terminal and the called terminal via the sound effect server, and the sound effect server detects a DTMF signal when a button is pressed from the calling terminal or the called terminal during a call. The sound effect is simultaneously sent to the calling terminal and the called terminal.

In this case, when the call path is set via the sound effect server according to whether the caller subscribes to the sound effect service as described above, when the DTMF signal is generated from the called party, the sound effect server is connected to the number button of the called party that generated the DTMF signal to the DB server. It is determined whether there is a specified relationship with the effect sound source and whether the called party subscribes to the sound effect transmission service, and the sound effect server may directly determine the subscriber information by holding the subscriber information.

As shown, first, as the number of the called terminal is input from the calling terminal and a call is attempted (S201), the calling exchange requests the location information to the calling home location register (S202).

The calling party's home location register determines whether the caller who attempted the call subscribes to the sound effect service and the activation state of the service (S203), and requests the location information including information of the called party's home location register when the caller is not a service user. The response message is transmitted to the originating exchange (S204).

Next, when the calling side exchange requests the called party's location information to the called party's home location register according to the received party's home location register information (S205), the called party's home location register registers the effector service of the called party and The activation state of the service is determined (S206).

In this case, when the called party is a sound effect service user, the called party home location register requests routing information including routing information of the sound effect server to the called side exchange (S207), and the called side exchange exchanges the received routing information. According to the sound effect server and the call to establish a call (S208).

In addition, the called party exchange sends a response message for the routing information request to the called party home location register (S209), and the called party home location register registers the sound effect server in the response message for the location information request from the calling exchange. The IP information is transmitted to the originating exchange (S210).

The originating exchange that receives the IP information of the sound effect server establishes a call path with the sound effect server according to the IP information (S211).

Therefore, as in the description of FIG. 2, even if the caller is a subscriber of the effect sound service, even if the caller is a subscriber of the effect sound service, the calling exchange and the called exchange exchange a call path between the calling terminal and the called terminal via the sound effect server. When the button is pressed from the called terminal during a call, the sound effect server detects a DTMF signal and simultaneously transmits the corresponding sound to the calling terminal and the called terminal.

At this time, if both the caller and the called party are not subscribers of the sound effect service, the voice call path by the general call processing method will be set.

Next, FIG. 4 is a flowchart illustrating a call setup process of the two-way effect sound transmission service method during a call according to the third embodiment of the present invention, and illustrates a call setup process of the sound effect server through a feature code.

In this case, the feature code refers to a combination of letters (*, #) and numbers that can control the call setup process by prefixing the number of recipients when a call is attempted.

As shown, when the caller attempts to call by entering the feature code (FC) and the number of the called terminal (S301), the calling exchange requests the location information to the calling home location register including the feature code ( S302).

Next, when the calling party home location register checks the feature code and the feature code requesting the sound effect service, the calling home location register transmits a response message to the calling party exchange message including the routing information of the sound effect server. If (S303), the originating exchange exchanges the call with the sound effect server according to the routing information (S304).

Subsequently, steps S305 to S310 showing the call establishment process between the sound effect server and the destination exchange are the same as those of steps S106 to S111 in the description of FIG.

On the other hand, when the call path is established via the sound effect server according to whether the caller subscribes to the sound effect service as described above, when the DTMF signal is generated from the called party as in the description of FIG. 2, the sound effect server sends a DTMF signal to the DB server. It is determined whether or not the called party subscribes to the sound effect transmission service by determining whether there is a designated relationship between the called party's number button and the effect sound source, and the sound effect server may directly determine the subscriber by holding the subscriber information.

Lastly, FIGS. 5A and 5B are flowcharts illustrating an effect sound transmission process of the two-way effect sound transmission service method during a call according to the present invention after the call setup process of FIGS. 2 to 4. 5B is a flowchart of a case where a sound effect transmission is requested from a called subscriber.

As shown in Fig. 5A, while the calling exchange establishes a call path with the called exchange via the sound effect server (S401), a call is made between the caller and the called party while the caller who is the subscriber of the sound effect service presses a specific button. When the DTMF signal is generated by pressing (S402), the DTMF signal is transmitted from the originating terminal to the sound effect server through the originating exchange (S403).

The sound effect server queries the effect sound source to the DB server by recognizing the originator of the received DTMF signal and DTMF signal (S404), and the DB server for each shortcut number set for the corresponding button of the caller who requested the transmission of the sound effect. According to the effect sound source code information, the effect sound source code and the corresponding sound effect are transmitted to the sound effect server (S405).

When the sound effect is transmitted from the DB server, the sound effect server bidirectionally transmits the sound effect to the calling terminal and the called terminal (S406).

In addition, as shown in FIG. 5B, while a call is connected between the calling exchange, the sound effect server, and the called exchange (S501), while the call is being made between the calling party and the called party, the called party, the subscriber of the sound effect service, presses a button and displays a DTMF signal. Is generated (S502), DTMF signal is transmitted from the called terminal to the sound effect server through the called-side exchange (S503).

The sound effect server queries the effect sound source to the DB server by recognizing the originator of the received DTMF signal and DTMF signal (S504), and the DB server for each shortcut number set for the corresponding button of the called party requesting the transmission of the sound effect. The effect sound source code and the corresponding sound effect are transmitted to the sound effect server according to the effect sound source code information (S505).

Similarly, when the sound effect is transmitted from the DB server, the sound effect server bidirectionally transmits the sound effect to the calling terminal and the called terminal (S506).

At this time, the sound effect server receives the DTMF signal, distinguishes the caller and the called party by distinguishing whether the DTMF signal is transmitted from the calling terminal or the receiving terminal, and when the call is connected to the call through the sound effect server As described above, the effect sound transmission service of the called party as well as the called party can be used as described above.

The channel is divided into a transmission line and a reception channel of the exchange so that the sound effect server can distinguish whether the DTMF signal is a signal from a transmitting side or a signal from a receiving side.

At this time, when the call path is set via the sound effect server according to the caller's subscription, if the DTMF signal is generated from the called party's side, the sound effect server designates the number button of the called party that generated the DTMF signal to the DB server and the effect sound source. It is determined whether or not a relationship exists, and whether or not the called party subscribes to the sound effect transmission service, and the sound effect server may directly determine the subscriber information by holding the subscriber information.

In addition, in the above-described embodiment of the present invention, the case where the calling terminal and the called terminal make a call using the mobile communication network has been described as an example, but the sound effect service device including the sound effect server and the DB server includes a call through the PSTN network.
