Referring to Figure 3 will be described in detail a preferred embodiment of the present invention made of the above configuration means.

General call storage service In order for a registrant to save a call during a call, the registrant must apply for a call storage service and be registered as a subscriber.

Therefore, a general telephone subscriber having an analog phone needs to call an application server in order to apply for a call storage service (S20).

When a call is made to the application server, the phone number arrives at the access gateway, and the access gateway is connected to the application server under the control of the soft switch.

When the call is connected to the application server, the application server checks the telephone number of the call storage service applicant and sends a service announcement to the call storage service applicant, and the call storage service applicant applies for the service according to the service request announcement ( S20).

When the call content storage service applicant requests a service, the application server confirms a service request and then requests a call recording server to secure a call content storage space necessary for a call subscriber who applied for call storage service (S21).

The call recording server receiving the request for securing the call storage space secures the storage space of the telephone subscriber who applied for the call storage service, registers the storage space information of the telephone subscriber, and then notifies the application server of the result. The result of notifying the application server of the call recording server means an index value indicating the telephone subscriber who applied for the call storage contents service and the storage space allocated to the subscriber (S22).

The application server receiving the notification registers the telephone subscriber who applied for the call storage service as a service providing registrant and notifies the applicant of the call storage service that the call storage service is registered, and the subscriber who applied for the service receiving the notification. Recognize that the service application is completed (S23 ~ S24).

Recognizing that the call content service application is completed, the call content storage service registrant dials the other party's telephone number to make a call with the other party's subscriber, and the access gateway receives the phone number and is controlled by a soft switch to connect to the other party's subscriber's phone. The access gateway is connected to the access gateway, which is controlled by a soft switch to connect a call to the other party, so that a call is established between the call content storage service registrant and the other subscriber (S25).

When the call is formed, the subscriber applying for the call storage service and registered as a service registrant requests the application server to store the call contents during the call. For example, if # 100 is pressed after the hook flash, the access gateway is accessed. Determines that this is a service call of the call content storage service registrant for call storage and connects to the application server (S26).

The application server receiving the call content storage request commands the call recording server to store the call content, and informs the index value of the telephone subscriber who has received the call content storage service registration and the index value of the storage space allocated to the service registrant ( S27).

After the application server commands the call recording server, at the same time, the subscriber registered to the call content storage service notifies the access gateway to which the subscriber is connected and the access gateway to which the other party is connected to deliver the contents of the call to the call recording server as well as the other party. (S28).

After the notification is made, the call is stored in the call recording server and stored in the call recording server until the end of the call. The call recording server stores the allocated call value corresponding to the index value given to the call storage service registrant. The content of the call is stored in the space (S27).

When the call is terminated between the call content storage service registrant and the counterpart phone subscriber, the application server notifies the telephone subscriber who has registered the call content storage service that the call content is completed. After a certain time, the application server attempts to make a call with a telephone subscriber who has registered a call content storage service, and informs the service broadcaster that the call content storage is completed by lifting the handset (S28).

The registrant of the call content storage service who has been informed that the call content storage has been completed may be able to listen to the stored content at any time later.

Hereinafter, a preferred embodiment in the case where the stored call contents are to be listened to will be described in detail with reference to FIG.

 To store the call details, the service registrant must first call the application server to listen to the call contents. When the phone is dialed to the promised application server phone number, the access gateway is connected to the application server under the control of the smart switch (S31).

Then, the application server confirms that the telephone subscriber who is calling to listen to the call is registered in the call storage service and listens to the announcement, which is' 1 if you want to listen to the stored call. Press, and to delete the stored call details, press 2 times and the message will be told (S32).

According to the announcement, when a subscriber registered in a call storage service selects to listen to a call, the application server tells a call recording server an index value of a person registered in the call storage service and an index value of storage space allocated for the registered person. While delivering a command to tell the call content storage service registrants the selected call content (S33).

The call recording server receiving the command finds the stored call contents by referring to the index value of the call contents storage service registrant and the index value of the allocated storage space, and informs the call contents storage service registrant of the call contents, and stores the stored contents. After all, the completion message is sent to the application server (S34).

Receiving the completion message, the application server informs the call content storage service registrant requesting to listen to the call storage contents to receive the announcement regarding the processing of the stored message, processes the stored message according to the call content storage service registrant's selection, and terminates the call. (S35-S36).

The announcement broadcast regarding the stored message processing means a message such as "1 to hear the message again, 2 to delete the message heard, 3 to hear another message" and the like.

As described above, in the next-generation communication network (NGN), a general telephone subscriber can call an application server to apply for a call storage service and receive a registration as a service provider. The application server can be called to obtain a storage service and the call can be stored in the storage space allocated to the call recording server. Then, at any time after the call is terminated, the application server requests the stored call contents to control the call recording server so that the stored call contents can be heard by the service registrant.

According to the present invention having the above-described configuration means and embodiments, through the call content storage service in the next-generation communication network, the general subscriber only secures a storage space in a server connected to the next-generation communication network without preparing a terminal for a separate recording. The service can be provided at a low cost.

In addition, when registering a service using a system such as the present invention at a government office such as a police station or a fire station, it is possible to reduce the problems caused by problems in the operation of the public office by making a prank call to an existing government office and preventing the prank call. There is.

On the other hand, if necessary, evidence that can be used as an important material for civil / criminal can be collected simply and inexpensively, and it is effective for civil / criminal security as a system useful for securing the location of criminals.
