Hereinafter, the pre-call connection tone service method according to the present invention will be described with reference to FIG. 3. First, in step S301, the originating terminal transmits call connection information including the called terminal information to the originating exchange, and in step S303 the originating exchange requests a call connection to the called exchange corresponding to the called terminal. In step S305, the destination exchange transmits a request response signal to the originating exchange, and in step S307, a callset is requested to the destination terminal.

Here, the called exchanger may determine whether the called terminal subscribes to the call service according to the present invention, and may provide preset advertisement information instead of the ring back tone when the call service subscriber is a call service subscriber.

That is, when a call connection request is made to the call service providing server with the called terminal information in step S309, the call service providing server transmits a request response signal to the destination exchange in step S311, and transmits a connection completion signal in S313.

In step S315, the call service providing server extracts the advertisement information corresponding to the called terminal, and transmits the advertisement information to the calling terminal instead of the ring back tone through the called exchange.

When the destination exchange receives the connection signal from the destination terminal in step S317, the destination exchange transmits a call release request signal to the call service providing server in step S319. Upon receiving the call release request signal, the call service providing server releases the call in step S321 to terminate the transmission of the advertisement information, and transmits a request response signal corresponding to the call release request signal to the destination exchange.

In step S323, the destination exchange transmits a connection completion signal for the voice call to the calling exchange, and in step S325, a voice call is made between the calling terminal and the called terminal.

Hereinafter, when the called terminal is oak hook, it has been described on the basis of the termination of the pre-call service, it can provide the pre-call service by various methods.

According to the embodiment of the present invention, types of call services according to the present invention are shown in Table 3.

The determination of the type of advertisement information may be configured to terminate when the recipient terminal hooks off, or may be configured to send all the designated advertisements regardless of whether the recipient terminal is hooked off. And no-cut service refers to a service that listens to the end without interrupting advertising or music even if the other party picks up the handset.

In addition, provided advertisement information may also be provided sequentially after setting a plurality of advertisement information, or may be provided at random to reduce weariness caused by the caller to the same advertisement information.

And it is possible to provide a pre-listening service that provides only the set advertisement information to the caller or the called party.

Busy service

The basic pre-call service is configured to be provided to the calling terminal, but by setting the call path between the terminal and the call service providing server 400 when the call is set, the call service is configured to be provided to both parties of the call according to the present invention. Can be. The overall service providing procedure for providing such a service is illustrated in FIG. 4A, and a diagram illustrating a call path setting method according to a service request according to an exemplary embodiment of the present invention is illustrated in FIG. 4B.

FIG. 4A is a diagram illustrating a whole service providing procedure during a call according to a preferred embodiment of the present invention, and FIG. 4B is a diagram illustrating a call setting method according to a service request according to a preferred embodiment of the present invention.

Referring to FIG. 4A, first, in step S410, a call path is set between the calling terminal, the called terminal, and the call service providing server 400. After setting the call path as described above, the service type is determined using the service identifier in step S420, and a service during the call corresponding to the determination result is provided. That is, if the requested service is the background sound service, the background sound service is provided in step S430, and if the modulated sound service, the modulated sound service is provided in step S440. If the call recording service, the call recording service can be provided in step S450.

The call path setting method in the service providing method during a call according to the present invention can be classified into two types. That is, the call path setting method includes a first method configured to unconditionally set a call path for providing a service during a call when the user terminal subscribed to the service requests a voice call, and a signal and a busy service requesting a voice call. The second method may be configured to classify a signal for requesting and selectively setting a call path for providing a busy service only to a terminal requesting a busy service.

For example, according to the first method, a user may provide a service during a call according to the present invention by operating a call button after inputting a counterpart phone number like a conventional voice call. On the other hand, according to the second method, when the user operates the call button by inputting the identification number and the counterpart phone number, the service during the call according to the present invention is provided, and only the counterpart phone number is input to operate the call button. The case may be configured to provide only a voice call service as in the conventional method.

According to the first method, the user can conveniently be provided with the service during the call by one button operation during the call, while it is possible to set an additional call path for all the voice calls, so that more unnecessary channels can be set. There is this. On the other hand, according to the second method, the user has to perform a separate button operation, but it is not necessary to allocate an unusable channel, so that the channel can be efficiently used.

Referring to FIG. 4B, first, it is determined whether a method for setting a call request for the service corresponds to one of a first method and a second method in step S450.

As a result of the determination of step S450, in the case of the first method of establishing a call path when the call is connected to the above method, in step S455 only the service subscription according to the present invention is determined and the call path is set. In other words, if a service subscriber, in step S460 provides a busy service according to the present invention, and if not a service subscriber, provides a general voice call service in step S465.

On the other hand, when it is determined in step S450 that it is determined whether the identification number is included in the second method of establishing a call path, it is determined in step S453 whether the identification number is included in the request signal. As a result of the determination in step S453, if the identification number is not included, the flow proceeds to step S465 to provide a general voice call service without setting a separate call path.
