It consists of an advanced intelligent network (AIN) system (40).

The exchange MSC 200 is equipped with a CMX (Conference Mixer, 25) device that performs a three-party or multi-party conference call, using the conference call function of the CMX (25) temporary call to the call line between the caller, the called party By additionally setting a call line (i.e., a recording line) to a storage means (SCP or recording server of the intelligent network), the temporary storage means can easily receive call tone data between the calling party and the called party.

At this time, the call data is transferred to the recording server 50 or the SCP DB 44 through the conference call function for the one-to-one call as well as the one-to-multi call between the called party and the called party. It is possible to transmit, and even if a new caller is added during recording, the tone data between them can be transferred.

The HLR 30 is a device for managing location information, terminal status, additional service registration, etc. of a terminal subscriber in a mobile communication system, and an SSP (Service Switching Point) 41 of an intelligent network refers to the HLR 30. It is an intelligent network switch that checks whether the called party is a subscriber of the intelligent network service and links the intelligent network system 40 to the mobile communication network.

The recording server 50, as the caller or called party requests the recording of the call, by making a database of call tone data between the caller and the called party temporarily stored in the SCP DB 44 (or recording server 50) for each subscriber It manages and provides the ARS service or inquiry and management service about the call tone data to subscribers on the wired / wireless internet through PSTN, WEB, or WAP.

To this end, the recording server 50 should be provided with a web, a swap server, or an ARS server device according to its implementation form, and must be provided with various interfaces accordingly.

In addition, the recording server 50 is a management function for the call recording data, play or delete function for the recording data, download function, time or call party classification function, retransmission function, reprocessing of voice data and audio insertion Function, etc.

On the other hand, the intelligent network system 40 by interworking No.7 common network and mobile communication network hierarchically separates the connection of simple call and complex service control, create and manage new services quickly and conveniently, effectively Network system for processing.

FIG. 2 illustrates a schematic internal block configuration of such an intelligent network system. The intelligent network system includes an SSP (Service Switching Point) 41, an IP (Intelligent Peripheral 42), an SMP (Service Management Point, 45), It consists of SCP (Service Control Point, 43) and DB (44).

The SSP 410 is an intelligent network switch for interworking a mobile communication network and an intelligent network, and performs a function of recognizing an intelligent network service call in a call of a mobile communication user and connecting a call according to information required for processing an intelligent network service call. The SSP 41 provides a call control function (CCF), which is a call control function providing call and service processing and control functions, and a set of functions required for interaction between the SCPF and a service control function (SCF) of the SCP 43. It includes functional means such as SSF (Service Switching Function).

The IP 42 is an intelligent information providing system, which is connected to one or more SSPs 41 and SCP 43 through a signal network, and collects customized and continuous announcements, voice recognition, voice synthesis, and DTMF. It also provides special resources such as network interface, etc., and provides interface function to subscribers so that information can be flexibly exchanged between subscribers and intelligent network.

The SCP 43 has a service logic program (SLP: Service Logic Program) necessary for providing an intelligent network service, and has a DB 44 for storing and providing data. In particular, SCP 43 is provided with a logic program of a recording service during a call according to the present invention, and when the intelligent network is linked to the call, it controls the procedure of recording service accordingly.

In addition, the SMP 45 controls service management, service introduction, service deployment, and the like, and performs database management, network monitoring and testing, network traffic management, network related data collection, and the like. To this end, the SMP 45 provides an interface with an external system of an intelligent network such as an HLR, a customer service & billing system (CSBS), a web server, a network management system (NMS), a location server, and the like. In addition, SCE (Service Creation Environment) is a means for defining, developing, and testing intelligent network services.

Hereinafter, with reference to FIGS. 3 to 5, the process of recording call tone data between the caller and the receiver through the above-described system will be described in more detail.

3 shows a process of setting up a call line between a caller and a called party.

First, when a call is attempted by entering a called terminal number in the calling terminal 60 (S301), the calling switching center 20-1 checks the information of the called terminal 70 with reference to the HLR 30, and The destination switching center 20-2 requests the establishment of the call line. (S302)

Accordingly, the destination switching center 20-2 calls the corresponding destination terminal 70 and, as the destination terminal 70 responds, establishes a call line between the calling terminal and the called terminal (S303).

In addition, when the caller enters a number of another called terminal and requests a conference call, the calling switch office 20-1 executes the CMX 25 to make a conference call between the called terminals 70 and the calling terminal 60. FIG. Configure lines to enable multiparty calls.

On the other hand, the present invention is to determine whether the call is an intelligent network service and recording service call in the process of establishing a call between the caller and the receiver as described above, Figure 4 is to temporarily store the call content When using SCP DB (44) of intelligent network as a means.

FIG. 4A shows a process of establishing a recording line to SCP 43 through the conference call function of the switching center CMX and temporarily storing call tone data between caller and receiver in SCP DB 44.

In the process of establishing a call between the originating terminal 60 and the terminating terminal 70 as described above with reference to FIG. 3, the SSP 41 of the originating switching center 20-1 refers to the HLR 30. Check whether the call is an intelligent network service call. (S401)

At this time, in case of an intelligent network service call, that is, when either one of the caller or the called party is a subscriber of the intelligent network service, the SSP 41 links the intelligent network system 40 to the call and identifies the service subscriber's identification information (terminal number). ) Is provided to SCP 43. (S402) SCP 43 also confirms that the subscriber is a subscriber of the in-call recording service according to the present invention.

At this time, if the subscriber (sender or the called party) is a user registered in the recording service of the present invention, the SCP 43 sends the SCP to the originating switching center 20-1 through the SSP 41 according to the logic program of the recording service. It is requested to add the conference call to 43. (S403)

Accordingly, the originating switching center 20-1 executes the conference call function of the CMX 25 to execute a three-way or multi-party call line consisting of the originating terminal 60, the called terminal 70, and the SCP 43 (drawings). O), SCP (43) will be able to receive the ring tone data between the caller, the called party as it is (S404).

In addition, SCP 43 temporarily stores and manages the call tone data received in the SCP DB 44 (S405).

In FIG. 4B, when the call is terminated between the caller and the called party, and the caller (service subscriber) transmits a recording request DTMF signal to the SCP 43 to request a call recording service (S406), the SCP 43 displays the DB ( The call tone data temporarily stored in 44 is transmitted to the recording server 50 together with the requested subscriber information (S407).

At this time, even after the call line is released between the calling terminal 60 and the called terminal 70 (indicated by x in the drawing), the call is still activated between the calling terminal 60 and the SCP 43 (o is shown in the drawing). Therefore, after the call is terminated, the calling terminal 60 can transmit the recording request DTMF signal to the SCP 43 as described above.

In addition, the recording server 50 stores and manages the data transmitted from the SCP 43 as call tone data for the requestor (sender). In addition, the ARS provides the subscriber with the inquiry and management service for the recorded data through the wired / wireless Internet (S408).

In the above, the recording request is not limited only after the end of the call, but also during the call. In addition, when both the caller and the called party are subscribers of the recording service and both request call recording, the recording server 50 stores the call tone data as data for the caller and the called party, respectively.

On the other hand, Figures 5a and 5b is a view showing a recording process during a call for the case of using the recording server 50 directly as a temporary storage means of the call sound.

First, in the process of establishing a call between the calling terminal and the called terminal, the SSP 41 of the calling switching center 20-10 refers to the HLR 30 and checks whether the calling party or the called party is a member of the intelligent network service (S501). In the case of the subscriber of the intelligent network service, the intelligent network system is interlocked with the call and the identification information of the subscriber is transmitted to the SCP 43. (S502)

The SCP 43 checks whether the subscriber (caller or called party) of the intelligent network service is a user subscribed to a recording service during a call according to the present invention, and if the subscriber is a service subscriber, according to a predetermined logic program of the recording service, 20-1) provides the location information of the recording server 50 and requests to perform the conference call function (S503).

Accordingly, the originating switching center 20-1 executes the conference call function of the CMX 25 to additionally set the recording line to the recording server 50 in the call line between the calling party and the called party. (S504)

Then, the recording server 50 receives the call sound data between the caller, the called party through the recording line and manages it as temporary storage data.

In addition, in FIG. 5B, in a state where a call is completed between the caller and the called party and the caller ends the call, the caller still transmits a predetermined DTMF signal through a recording line to the active recording server to request recording of the call. (S505)

Accordingly, the recording server 50 databases the temporarily stored call and call tone data between the caller and the caller in the DB 55 as data for the requester (caller). On the other hand, when all callers (callers, called party) end the call without a separate call recording request, the recording server 50 deletes the temporarily stored call sound data.

In addition, the recording server 50 provides the subscriber with the inquiry and management service for the call tone through the ARS service and the wired and wireless Internet (S506).

6 is a schematic flowchart of a recording method during a call using the intelligent network and the conference call function according to the present invention.

In Fig. 6, in order to use the recording service of the present invention, the terminal user first subscribes to the recording service according to a predetermined procedure, and this information is registered and managed by the HLR 30 and the SCP 43 of the intelligent network. )

Then, as the caller attempts to make a call with the called party through the switching center, the switching center MSC 20 sets up the call line (S602), and at the same time, the SSP 41 of the calling switching center 20-1 The caller or the receiver of the call checks whether the subscriber is an intelligent network service, and if it is an intelligent network subscriber, SCP 43 of the intelligent network verifies whether the caller or the called party is a subscriber of the call recording service (S603).

At this time, if either of the caller or the called party is not a subscriber of the recording service, the call proceeds to the general call without the recording service.

On the other hand, when either party is a subscriber of the recording service, the SCP 43 requests the originating exchange 20-1 to execute the conference call function, and the originating exchange 20-1 calls the conference call of the CMX 25. By executing the function, the recording line to the SCP 43 (or recording server 50) side is additionally set. (S604)

As a result, the SCP 43 (or the recording server 50) can receive call tone data between the caller and the called party, and temporarily stores and manages the call tone data.

When the subscriber (sender or the called party) transmits the call recording request DTMF signal while the call is in progress or after the call is completed (S606), the SCP 43 (or the recording server 50) is temporarily stored in the meantime. Call sound data between the calling party and the called party is transmitted to the recording server 50, and the recording server 50 stores the call data of the requesting subscriber. (S607)

At this time, when both the caller and the called party terminate the call without a separate call recording request, the temporarily stored call tone data is deleted.

In addition, the subscriber accesses the recording server 950 through the ARS and the wired and wireless Internet, and inquires and manages his / her call data.

As described above, in the intelligent network switching system according to the present invention, an automatic recording and inquiry / managing method of a call using a conference call function, and a system thereof, by automatically recording a call on a server using an intelligent network service and a conference call function, The user's convenience and efficient operation of the recording system can be achieved, and the user can easily provide the user with the inquiry and management service regarding the call data through various routes.
