The present invention relates to a method and a system for providing a sound effect during a call, and more particularly, to a method and system for providing a sound effect during a call that can provide a sound effect at the request of a user during communication.

Older phone calls were focused on features for voice calls only. However, with the advance of technology, the functions of enriching the conventional simple voice call-oriented telephones in telecommunication terminals and networks have begun to be added, and this phenomenon has become more active with the advent of mobile terminals. In addition to the services that are made before a call such as a back tone, a service providing an effect sound, a voice modulation, or a background sound (hereinafter collectively referred to as an effect sound) related to the contents of the call has been provided during the voice call.

Looking at the conventional sound effect providing service from the user's point of view, after the user subscribes to the service, the user requests the service through the wireless Internet, and attempts to voice call again receives the sound effect service. Another service method receives an effect sound service by simultaneously transmitting a key requesting the effect sound service to the network together with the called number.

However, in the former case, it is cumbersome to access the wireless Internet every time in order to receive the service. In addition, in the latter case, there is no need to connect to the wireless Internet, but there is a problem of receiving unnecessary services because the receiver of the called party requests an effect sound service without being confirmed, and also needs to apply for the service before the call. There is a problem that the called party cannot request a service.

The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a method and a system for providing an effect sound during a call, in which a subscriber requests an effect sound service during a call and thus provides an effect sound service. will be.

Preferably, the MSC establishes a call between the effect sound providing server and the calling party using the calling party's number as a calling party number, and uses the called party's number as the calling party number and the effect sound providing server. A call is set up between the called party, and the effect sound providing server forms the second call path using the calling party and the called party number as the calling party numbers.

Advantageously, said service request signal comprises one or more of a predetermined number, a predetermined key signal, a voice signal, and a DTMF signal.

Preferably, the effect sound in the present invention includes all the information (eg, background sound, voice modulation, sound, audio, or character) provided on the call path except for the voices of the calling party and the called party during the call.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a configuration diagram schematically showing the configuration of a system for providing a sound effect during a call according to an embodiment of the present invention.

Referring to FIG. 1, an effect sound providing system during a call according to an embodiment of the present invention includes an MSC 230 and an effect sound providing server 300.

 The MSC 230 according to the present invention forms a first call path between the calling party and the called party 100 according to a call (called or called) request, and requests a service from the calling party or the called party 100. When a signal FC (FeatureCode) is generated, a second communication path is formed between the calling party 100 and the called party 100 through the effect sound providing server 300, and the first calling path Release it.

The effect sound providing server 300 stores the terminal number of the service subscriber and the effect sound selected by the subscriber. When the second call path is established, the effect sound providing server 300 provides the effect sound to the calling terminal and the called terminal 100 through the second call path, respectively.

When the service request signal is generated from the calling party or the called party 100, the MSC 230 checks whether the calling party or the called party subscribes to the effect tone service, and as a result of the check, the calling party or the calling party When the called party 100 subscribes to the effect tone service, the second call path is formed.

According to an embodiment, the MSC 230 queries the HLR 240 to confirm whether the calling party or the called party 100 subscribes to the effect tone service. For example, when an FC is generated from the calling party or the called party 100, the MSC 230 transmits an inquiry corresponding to the FC or FC to the HLR 240. When the HLR 240 receives an inquiry corresponding to FC or FC, the HLR 240 checks whether the calling party or the called party 100 is a subscriber terminal of the service by referring to a subscriber profile. If the calling party or the called party 100 is the subscriber, the HLR 240 is responsible for establishing the second communication path according to the present invention in response to the inquiry corresponding to the FC or FC. Necessary information, for example, values of parameters such as RoutingDigits or TerminationList, ActionCode, and DMH_RedirectionIndicator defined in IS-41 are provided to the MSC 230 to allow the MSC 230 to form the second call path.

According to an embodiment, if the FC is generated at the originating side (terminal: 100) and the originating side is a terminal 100 registered by the MSC 230, the MSC 230 is a VLR. The caller may confirm that the calling party 100 is a subscriber of the service, and form the second communication path according to the information from the VLR.

Also preferably, when the service request signal (FC) is generated from the originating side or the called party 100, the MSC 230 is the one that generated the service request signal, the MSC 230 is the current service Check whether it is generated from the terminal, and if the terminal generating the service request signal is serviced by the MSC (230) performs the second communication path forming process according to the present invention.

Preferably, the service request signal FC includes one or more of a predetermined number, a predetermined key signal, a voice signal, and a DTMF signal.

According to an embodiment, the MSC 230 establishes a call between the effect sound providing server 300 and the calling party using the calling party number as the calling party number, and sets the called party number as the calling party number. A call is established between the effect sound providing server 300 and the called party. Then, the effect sound providing server 300 forms the second call path using the calling party and the called party number as the calling party numbers.

Hereinafter, with reference to the accompanying drawings will be described in more detail than the effect sound providing system and its operation shown in FIG.

2 to 4 are diagrams for conceptually explaining a process of providing an effect sound service during a call in the system shown in FIG. 1.

FIG. 5 is a diagram illustrating a process of providing an effect sound service during a call to a terminal subscribed to the service in the system shown in FIG. 1.

In addition, in the present embodiment, a case in which a subscriber subscribed to the service is described by way of example, those skilled in the art will fully understand that the present invention can be applied to an incoming call.

Referring to FIG. 5, when receiving a call request from the originating terminal 100 through the base station 210, the MSC 230 performs the normal procedure according to the call request, for example, according to the IS-41. As shown in FIG. 2, between the caller and the called terminal 400, a first call path is established (S1 to S5).

In order to receive an effect tone service during a call, when the user of the calling terminal 100 generates a service request signal FC, the FC is provided to the HLR 240 through the base station 210 and the MSC 230. do. Alternatively, when the FC is received by the MSC 230, the MSC 230 may make an inquiry about the FC to the HLR 240. In addition, after the first call path is formed, the FC is generated when the called terminal 400 responds, and the users of the calling and called terminals 100 and 400 are in a call or the user of the called terminal 400. May occur before the response (S6 to S9).

When receiving the inquiry FC from the MSC 230, the HLR 240 checks whether the calling terminal 100 is the service subscription terminal based on the subscriber profile of the calling terminal 100. If the originating terminal 100 is a terminal subscribed to the service, a response message (FeatReq RR) including information (RoutingDigits or TerminationList, ActionCode DMH_RedirectionIndicator, etc.) necessary for providing an effect sound service may be received. 230 to (S10).

When receiving the response message from the HLR 240, the MSC 230 establishes a call according to the routing number of the effect tone providing server 300 included in the "RoutingDigits or TerminationList" parameter of the response message. . At this time, the calling party number of the call request message (IAM) uses the number of the called terminal 400. Subsequently, in order to establish a call between the called terminal 400 and the effect sound providing server 300, the MSC 230 sets up a call again according to the routing number of the effect sound providing server 300. At this time, as the caller number of the call request message (IAM), the number of the caller terminal 100 is used (S11 to S14).

Then, the effect sound providing server 300 connects a call between the calling and called terminals 100 and 400 by using the numbers of the calling and called terminals 100 and 400 provided as the calling party number. As shown in FIG. 3, the call between the calling and terminating terminals 100 and 400 is formed through the first and second call paths in duplicate (S15).

When the second call path is formed or at the same time as the formation of the second call path, the MSC 230 releases the first call path, as shown in FIG. 4, of the calling and terminating terminals 100 and 400. While the call is established through the second call path, the effect sound providing server 300 sends and receives the effect sound requested by the user of the calling terminal 100 through the second call path 100. And 400, respectively (S16).

Therefore, according to the above configuration, the subscriber can receive the effect sound service by simple key operation during the call.

As described above, according to the present invention, it is possible to realize a method and a system for providing an effect sound during a call, in which a subscriber can request an effect sound service during a call and thereby provide an effect sound service.

Although the present invention has been described in detail by the above embodiments, the present invention is not limited thereto, and variations and improvements can be made without departing from the ordinary knowledge of those skilled in the art.
