1 is a schematic block diagram of a call recording / querying system according to the present invention.

As shown in FIG. 1, the recording / retrieval system of the present invention includes a base station 30 and an exchange station 40 for establishing a call line and establishing a network between a calling terminal 10 and a receiving terminal 20. , Recording server 50 for storing and managing call contents between receiving terminals, telephone 61, PC computer 62, and mobile communication terminal 63 for inquiring and managing recording contents through wired / wireless Internet and public telephone networks. ) And the like.

In particular, the system according to the present invention applies a conference call (conference call or multi-party call) function of the switching center 40 in order to transmit the call content between the caller and the receiver to the recording server 50. That is, when a call recording is requested from the caller (or receiver), the switching center 40 regards the recording server 50 as one of the multiparty calls, and the third party (or the caller, the receiver, and the recording server) constitutes the caller. By setting a call line between the above), the voice data of the caller and the receiver is transmitted to the recording server 50 side.

At this time, not only the one-to-one call between the caller and the receiver, but also the one-to-multi call may be transmitted to the recording server 50 through the conference call function.

In addition, a home location registration (HLR) 46 manages subscriber information and terminal location information, and the switching center 40 refers to each mobile communication terminal 10, 20 and a recording server with reference to this HLR. By knowing the status and location of 50), they are called and connected to the call line.

The recording server 50 databases and manages the call data received from the switching center 40 for each subscriber, and provides the subscriber with the inquiry / management service for the call recording data through WEB, WAP or ARS.

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 service 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.

FIG. 2 is a diagram illustrating the configuration blocks for performing a conference call function at the switching center 40.

The conference telephone processing block at the switching center 40 is composed of a time division switch 41, a control subsystem 42, a conference mixer (CMX) 43, and the like.

The time switch & link (TSL) 41 serves to switch a multi-party call line by allocating a channel in a time division manner to each call terminal of the conference phone.

In addition, the control subsystem 42 is a block that generally controls functions such as call processing and operation maintenance of the switching center CMX 43, and transmits call-related information to the CMX 43 to call processing and channel allocation. And so on.

The CMX 43 is a block that performs a conference call and a conference call function according to a predetermined process. That is, the PCM (pulse code modulation) voice signal is received from the time division switch 41 and performs a conference call function, and then the PCM voice signal is output to the time division switch 41.

The CMX 43 and the time division switch 41 are connected by sub-highways to exchange PCM voice signals.

The CMX 43 includes a conference call processor 44 and a recording request recognition unit 45.

The Advanced Conference Mixer Card (ACMC) 44 is a component that performs a conference call function by mixing a voice signal of a conference call participant. N-1 voice signals are added to the time slot of the time division switch 41 except for the voice signals.

The recording request recognition unit 45 determines whether there is a recording request before or during a call from the calling terminal 10 (or the receiving terminal).

The recording request may be recognized depending on whether a specific tone button (*, #, etc.) or a dual tone multi frequency (DTMF) signal of a dedicated button is received from the terminal.

When the recording request recognition unit 45 recognizes the recording request from the sender or the receiver as described above, the time division switch 41 is connected to the calling terminal 10, the receiving terminals 1 to n 20, and the recording server 50. Allocate each channel to establish a conference call line, and the conference call processor 44 performs a multi-party call function by mixing voice data of other participants in the call line of each channel.

Thus, the recording server 50 becomes a participant of the conference call, and can easily receive call data between the caller and the receiver.

The conference call processing method of the illustrated exchange station 40 is just one embodiment to which the present invention is applied, and the technical idea of the present invention is to provide a call to the recording server 50 by using a conference call method. The call voice data between the recipients is transmitted to the recording server 50 side.

On the other hand, Figure 3 is a flow chart showing the process of performing the call recording, when the caller requests recording before the call.

As shown in FIG. 3, the caller first requests a call recording service together with a call attempt by inputting a terminal telephone number (CTN) and a call recording key button (*, # button, etc.) of the receiver in the terminal. (S301)

The request method of the call recording service may be implemented by inputting a specific key button (*, #, etc.) or using a recording-only key button or a selection menu item.

The CMX 43 of the switching center 40 recognizes that there is a call recording service request from the call connection request data from the caller (S302) and executes the conference call function to make the calling terminal 10 and the receiving terminal 10. , And to establish a multi-call (multi-call) consisting of the recording server 50. (S303)

Accordingly, the recording server 50 can receive the call voice data exchanged between the calling terminal 10 and the receiving terminal 10.

When a call is made between the caller and the receiver (s), the recording server 50 temporarily stores the call data as caller data (S304).

If there is a recording stop request from the caller or the call ends during the call (S305), the recording server makes a database of the call data stored therein as call recording data of the caller (S306).

In the case of the recording stop request, it may be implemented in the manner of a promised specific key button (*, # button, etc.), re-click of the recording-only button, or a selection menu item.

4 is a flowchart illustrating a recording process when a caller or a receiver requests a call recording during a call.

Call recording service according to the request during the call is as follows.

That is, a one-to-one or one-to-many call line is formed between the caller and the receiver (s), and during the call (S401), the caller or the receiver inputs a specific key button (or a dedicated button, menu selection) to the switching center 40. The call recording service is requested. (S402)

When the switching center 40 receives a dual tone multi frequency (DTMF) signal of a specific key button for recording a call from the calling or receiving terminal (S403), it executes a conference call function and adds it to the call line between the currently set caller and receiver. To set the call to the recording server 50 side (S404).

Accordingly, the recording server 50 receives the call data between the caller and the receiver after that, and obtains information (CTN, etc.) about which terminal requested a service from the switching center 40.

Then, the recording server 50 temporarily stores the received call voice data as data for the service requester (S405).

Then, when there is a recording stop request from the service request terminal, or the call line of the request terminal is terminated (S406), the recording server 50 receives the call data between the caller, the receiver received during the call recording data for the service requester Databaseize (S407)

On the other hand, Figure 5 is the subscriber in the state in which the call data in the recording server 50 as a database for each subscriber (or mobile communication terminal), the subscriber inquires and manages the recording contents through the wired, wireless Internet or ARS It is a flow chart showing the process.

First, the subscriber accesses the recording server 50 through wired or wireless Internet or ARS (S501).

That is, when connecting to a mobile communication terminal, the WAP (Wireless Application Protocol) site of the recording server 50 is connected over the wireless Internet, and the WEB site provided by the recording server 50 when connected in a wired environment such as a PC computer. Alternatively, the user may access a page, and the general telephone may access the recording server 50 through an automatic response system (ARS) service.

When the user accesses the recording server 50 as described above, the subscriber goes through a predetermined authentication procedure for inputting a terminal number or ID and a password (P / W), and is granted access to the call data.

Accordingly, the subscriber can query and manage his / her own recorded call data in a database (S503).

At this time, the recording server 50, the following call recording data management services can be provided to the subscriber.

That is, the function of playing or deleting the recorded call, the function of downloading the recorded data to the mobile communication terminal or the computer terminal, the function of sorting each data by time or by the call counterpart, the call data to another mobile communication terminal A function of transmitting, a reprocessing function of adjusting a tone and volume of stored call data, or inserting a background sound or sound, and the like may be provided.

As described above, a method and a system for providing a call recording / query function in a mobile communication network according to the present invention apply a conference call function of an exchange office to record a call on a server and provide an inquiry and management service. Call recording is possible regardless of whether or not the support is provided, and the recorded contents can be easily inquired and managed through various routes.

In addition, since the contents of the call are stored on the server rather than the terminal, the amount of recorded data can be increased, and it can be stored for a long time.
