Voice over Internet Protocol (VoIP) refers to IP telephony technology for a set of facilities that deliver voice information using IP, which is a digital form of discrete packets rather than traditional protocols based on circuits such as PSTN, a public switched telephone network. Means to transmit voice information. The main advantage of VoIP and Internet telephony technology is that it integrates telephone service by utilizing existing IP network so that telephone users can receive long distance and international phone service in internet and intranet environment with only local call charge.

A technique for recording a voice file using such a VoIP network is disclosed in Korean Patent Laid-Open Publication No. 2004-0039638. Considering the method of recording the contents of the call between the caller and the receiver during the phone call by applying the recording technique, there are three ways as follows.

First, a method of recording the entire caller's and receiver's contents, from the moment the receiver responds to the caller's call connection request until the call is terminated by the on-hook of either the receiver or the sender. It is a way to record.

Second, the caller or receiver selectively records only the portion of the call that needs to be recorded by using a specific button or a predetermined recording program.At the time when the person who wants to record during the call starts recording at a specific moment and wants to end the recording. If you want to stop recording, but if you use the keytone of a specific button or in case of softphone, recording starts and stops by predefined command.

Third, a method of re-editing previously recorded voice data is a method of extracting, deleting, and modifying a specific section of the recorded voice data using an editing tool to produce a desired format.

However, in case of the first method, since the voice data must be sequentially searched from the beginning in order to search for a specific voice data section, the average search time is excessively consumed. There is a problem that can not be searched, there is a problem that the portion recorded by the user is stored in a number of files, and the same problem as the above first method exists in one voice data file.

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

1 is a block diagram showing the configuration of a call history recording system according to the present invention.

The calling terminal 110 requests a call connection with a specific receiving terminal to the switching center 130 through a predetermined communication network 120, and exchanges a call with the connected receiving terminal.

The communication network 120 plays a role of connecting communication between the calling terminal 110 and the switching center 130, and for this, a dedicated line network such as E1 and T1, a circuit switched network (CSN) including a public switched telephone network (PSTN), and ISDN. , A mobile network, or the like may be used.

Switching station 130 plays a role of connecting a call with the corresponding receiving terminal 150 when the calling terminal 110 requests a call connection to a specific receiving terminal 150, the VoIP network signal from the communication network 120 It is responsible for the conversion to 140 and vice versa. Therefore, each receiving terminal connected to the switching center 130 has its own IP address, and the switching terminal 130 has a predetermined table for matching the IP address for each receiving terminal with a predetermined digit number (telephone number). While receiving the digit number information for the call connection from the calling terminal 110 to retrieve the corresponding IP address to connect the call to the corresponding receiving terminal. The switching center 130 is a concept corresponding to a gateway in particular in a VoIP network, and the gateway receives voice data divided into packets from users in the VoIP network and sends it to another part of the intranet or uses a T1 or E1 interface. Is responsible for transmitting to the PSTN.

Since the VoIP network 140 has been described above with reference to FIG. 1, a description thereof will be omitted herein.

The receiving terminal 150 transmits and receives a call with the calling terminal 110 through the switching center 130 and transmits various recording related control signals to the recording device 160. Such a recording-related control signal includes a recording start control signal, a recording end control signal, and an index insertion signal in particular. In addition, the recording pause control signal, the recording cancellation control signal, and the index removal control signal may be further included.

Receiving terminal 150 may be provided with a predetermined selection means and recording signal generation module to allow the receiver to generate the recording-related control signal arbitrarily.

That is, when the receiving terminal has a structure consisting of a telephone terminal and a predetermined service server, the service server lists the various functions related to recording in a voice guidance manner to the telephone terminal and invites the user to select one of them. Press a specific digit input button (phone number input button) to generate a control signal for that function. In this case, the digit input button is the predetermined selection means.

In addition, when the receiving terminal is configured as a computer terminal and a headset, when the computer terminal displays a menu for selecting various functions related to recording on the monitor through a predetermined application program, the receiver selects a specific menu for a desired function. A control signal for the function is generated, and the application program at this time becomes the predetermined selection means. Of course, the service server and the computer terminal are each provided with a recording signal generation module for generating a predetermined recording-related control signal when a predetermined digit input button or a predetermined menu is selected.

On the other hand, in addition to the method of generating a recording-related control signal by the receiver's random selection as described above, the receiving terminal is automatically connected to the calling terminal and the call and generates a recording start control signal automatically, the call is terminated at the same time as the calling terminal and recording ends It is also possible to take the form of automatically generating the control signal. In this case, the service server and the computer terminal should be provided with a recording signal automatic generation module, respectively.

In addition, in generating the index insertion control signal, the receiving terminal may generate it according to a predetermined automated scenario instead of a random selection of the receiver. In this case, the service server and the computer terminal are each provided with a scenario module for this. do. Such a scenario module includes a pattern table defining one or more specific pattern data, and receiving or calling party call history data (which may be audio or video data, collectively referred to as 'media data') in real time. And a pattern search module for analyzing specific pattern data and searching for specific pattern data, and an index signal generating module for automatically generating an index insertion control signal when a specific pattern existing in the pattern table is searched.

Finally, the recording device 160 receives both the source media data and the receiving media data from the switching center 130 and repeats the temporary storage and updating continuously by the limited capacity, and then controls the recording related from the receiving terminal 150. When a signal is received, the source and receiver media data are mixed and recorded, an index is inserted, or the recording is terminated according to the type of the control signal. Detailed internal configuration and the role of each component to implement this will be described with reference to FIG.

2 is a block diagram showing the internal configuration of the call history recording apparatus according to the present invention.

The recording apparatus is composed of a packet processor 210, a mixer 220 and a storage 230. First, the packet processing unit 210 will be described.

The packet processing unit 210 captures a packet of a sending media data, a receiving media data, and a packet of various control signals, and a predetermined header if the captured packet is a media data packet or a recording related control signal packet. The control module 212 removes and transfers the control unit to each mixer unit and performs other control signal packets. In particular, the control module 212 includes predetermined protocols for implementing a VoIP network. Specifically, the control module 212 may include unique protocols and RTPs that are independently provided by H.323, SIP, or network equipment manufacturers.

Here, H.323 defines the components, protocols and procedures for providing real-time point-to-point and multipoint multimedia communication in packet-based networks, and SIP (Session Initiation Protocol) is a standard for establishing a VoIP connection. An application layer control protocol that establishes, modifies, and terminates sessions in a client-server fashion. In addition to the IP capabilities of VoIP, RTP is a protocol that allows all packets connected to the public network before establishing a TCP socket connection with the other party to ensure that packets arrive on time. It is a protocol that pings a network gateway and selects the fastest route based on the results.

When the recording start control signal is transmitted from the control module, the mixer unit 220 starts mixing of the temporarily stored source and reception media data to generate recording media data, and when the index insertion control signal is transmitted during the mixing. A data mixing module 221 performs mixing by attaching a predetermined index to a predetermined point, and terminates the data mixing when the recording end control signal is transmitted. Preferably, the source and receiving media data before mixing are included. Each may further include a codec conversion module 222 converting PCM (Pulse Code Modulation) to the data mixing module 221 and converting the PCM data mixed by the data mixing module 221 into a preset codec. Can be.

The codec conversion module 222 assumes that the media data is particularly audio data, the codec applied to the sender and receiver media data before mixing, and the PCM codec and the codec to be uniformly applied after the mixing (this is referred to as 'user codec'). To support G.711, G.723, G.728, G.729, etc. H.323 defines audio codecs in the range of 5.3 to 64 kbit / s, and basically uses G.711, a PCM method. However, G.711 is a codec designed to be used in the telephone network and is relatively unsuitable for communication on the Internet with less subscriber-side bandwidth. Therefore, most H.323 terminals provide high quality sound at 5.3kbit / s and 6.3kbit / s. G.723.1 or G.728 and G.729 provide high sound quality at 16kbit / s and 8kbit / s, respectively.

In addition, assuming that the media data is video data, since H.323 specifies that the video can be selectively supported, the codec conversion module 222 may use the H.261 / QCIF or H.263 codec for this purpose. Equipped with.

The storage unit 230 divides the media data received from the control module 212 into a sender and a receiver and temporarily stores the media data, and finally stores the recording media data generated by the mixer 220. This may be implemented as a local memory of the recording apparatus, or may be implemented as a predetermined client module requesting storage. In the latter case, a separate recording media data storage server should be provided externally.

Now, an operation process of a call history recording method or a recording system according to the present invention will be described with reference to FIGS. 3 to 4. 3 is a signal flow chart schematically showing an operation process of the call history recording system according to the present invention, and FIG. 4 is a flowchart sequentially showing an implementation process of the call history recording method according to the present invention.

When the calling terminal transmits predetermined digit information to the switching center and requests a call connection to a specific receiving terminal, the switching center connects the call to a receiving terminal having an IP address matching the received digit information (S401).

When a call is connected between the calling terminal and the receiving terminal, digitized call history data is generated according to the caller's or receiver's call initiation, which may be audio data or video data. The generated media data is present in the form of packets in the VoIP network. When the packet capture module of the recording apparatus arrives at the packet of the calling or receiving media data (S403), a predetermined packet for supporting VoIP among the packets is received. After separating the header of the extracted pure media data only and temporarily stores it in the storage unit (S405). At this time, the sender media data and the receiver media data are separately reached to the recording device, and the temporary storage is also made separately.

Now, if a predetermined selection means is selected at the receiving terminal or a predetermined scenario module is executed to generate a recording start control signal, which is captured by the packet capture module of the recording device, and then it is determined by the control module as a recording start control signal (S407). ), The mixer's data mixing module is executed to start mixing of the temporarily stored sender and receiver media data in step S405 (S409), and then receive an index insertion control signal from the receiver terminal in the same manner as in step S407. If a lower index (S411), a predetermined index is inserted into a specific point of the mixing media data (S413).

The steps S407 to S413 will be described in more detail with reference to FIG. 5 as follows.

The sending and receiving media data temporarily stored in the recording device may be coded according to the codec type supported by the VoIP network. That is, if the media data is audio data, it may be coded according to any one of G.711, G.723, G.728, and G.729. If the media data is video data, the media data may be coded according to any one of H.261 / QCIF or H.263. It will be coded accordingly (S510). In the present embodiment, it is assumed that the media data is audio data.

In the present invention, regardless of which codec the media data received from the VoIP network is coded, a predetermined conversion means is provided so that the user can uniformly convert and store the same into a specific codec desired by the user. That is, if the media data to be mixed is audio data, the source and receiver media data are uniformly converted to a PCM (Pulse Coded Modulation) code to perform mixing (S520), and then the mixed and merged PCM files are merged again. The conversion is to a predetermined specific codec (S530). In order to play such a role, the mixer of the recording apparatus may further include a codec conversion module. The specific codec set in the codec conversion module is set according to a predetermined policy determined in consideration of storage sound quality, storage capacity, and other conditions, and if the codec is not necessarily required and the codec supported by the original VoIP network is used as it is. Codec conversion module need not be provided separately.

When the index insertion control signal arrives between steps S510 and S530, a predetermined index is inserted and mixed in the media data being mixed (S550). Such an index can be implemented in two types. The first is to use a certain code as an index among the codes allowed by the user codec applied to the mixed media data, and the second is to use a code having a predefined data structure. It is used as an index.

6A illustrates an example in which the first index is implemented. That is, when the user codec applied to the mixed media data is G.723, a certain code, that is, "111000" (600) among the codes allowed by the codec, is defined as an index and corresponds to a point in time when an index insertion control signal is received. The code 600 is inserted at a specific point of the media data.

6B illustrates an example in which the second index is implemented. That is, a predetermined data structure may be defined for use as an index in the present invention, and in addition to the simple position display function, the data structure includes a predetermined field for providing predetermined brief information. For example, the predetermined data structure may include an index start 651, an index serial number 652, an index checksum (CRC) 653, an index information 654, and an index end. (Index end) 654 field.

The Index start 651 field indicates that the data is index data and also indicates the start of a specific index. The Index serial number (652) field indicates how many times the index is inserted. An index checksum (CRC) 653 field is provided to check whether or not the information provided in the index has not been altered in the mixing process. The Index Infomation field 654 briefly tells what the position where the index is inserted has or what content is included in the media data proceeding after the index. The index end 654 field indicates that the index is over and the media data thereafter. Such an index data structure is only one embodiment, and those skilled in the art will understand that various fields may be modified in the data structure.

Meanwhile, the first index data as described above may be preset in the data mixing module of the recording apparatus or transmitted from the receiving terminal together with the index insertion control signal, and the second index data may reach the index insertion control signal at the recording apparatus. Each time may be manufactured in the data mixing module, or may be produced in the control signal generating module, the control signal automatic generating module or the scenario module of the receiving terminal and transmitted to the recording apparatus together with the index insertion control signal.

4, when the recording end control signal reaches the recording apparatus (S415), the mixer terminates the mixing (S417) and returns to the step S403 again unless the call between the callees is terminated. Continue to run. If the call is terminated (S419), the recording operation is terminated.

Now, an embodiment in which a call history recording system or method according to the present invention is applied to an insurance consultation service system will be described with reference to FIG. 7.

The customer 710 calls a specific insurance company and talks with the insurance agent by talking to an insurance agent's counselor 740. The customer 710 transmits the insurance company's call center phone number information to the switching center 730 through the E1 or T1 class dedicated network 721, ISDN network 722, or PSTN network 723. Connect the arcs. An insurance company's call center has a number of counselors who can be connected to specific counselors through a private exchange office (PBX).

After the call is connected, the counselor explains various information necessary for insurance consultation, and when the customer decides to join the insurance, the counselor asks for various information necessary for the insurance, such as the subscriber's name, social security number, address, and whether to join the insurance. . At this time, the counselor selects a specific key of the counseling terminal or a specific menu of the monitor to instruct the recording apparatus to start recording so that all important information can be recorded. In addition, an index may be ordered for inserting personal information or a statement indicating consent.

In this case, the recording start and index insertion command may be executed by selecting a specific key or a specific menu of the counseling terminal every time a counselor needs it, or by executing a predetermined scenario program with one specific key or a specific menu selection. Recording start and index insertion can also be ordered automatically.

In the latter case, the scenario program recognizes a specific statement of a counselor, such as "I will start the insurance process", or a specific statement of the customer, such as "I will purchase insurance." Automatically orders recording start, recognizes phrases such as "subscriber's name" and "resident registration number" among counselor's comments, or recognizes phrases such as "Jeong Yujin" and "751101 -..." among customer comments. To insert an index.                     

The recording device 750 receives a recording start command from the counseling terminal, but records the call history of the customer and the counseling agent, mixes it, converts it into a single file, and stores the recording information in the recording information DB 755. Of course, when the index insertion command is contacted from the counseling terminal during the recording process, the recording is performed by inserting a predetermined index at the corresponding point.

In confirming the name, resident registration number, address, insurance details, health condition, intention of consent, etc. of the registered customer in the future, the recording information may replace the existing subscription document, and if the customer confirms the subscription, insurance In case of related disputes or the collection of insurance customer information, necessary parts can be quickly searched and provided through the index, and only specific information can be extracted and used.

The media data recording method and system including the index according to the present invention can be applied in a similar manner to call centers and counseling centers such as banks, securities companies, shopping malls, and the like.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by those equivalent to the scope of the claims.

 According to the present invention having the above-described configuration, since an index is inserted at a predetermined point of the recorded call history data, it is possible to quickly search for a point to be searched in the corresponding recording data in the future, and move to the corresponding point and play it back. In addition, since the index is inserted in real time during the recording process, it is possible to omit the trouble of having to edit the index for inserting the index separately after all the recording is finished.

In addition, the receiver is provided with selection means or a predetermined scenario module for transmitting various recording related control signals including index insertion, thereby allowing the receiver to perform recording in a more flexible manner.

In addition, in implementing the index, it is possible to prevent the recording speed from being affected by using a specific codec code, and by using a predetermined data structure, it is possible to receive brief information on the index in addition to the position display function.

In addition, since the codec conversion module is provided in the recording apparatus, regardless of the type of codec of the call history data before recording, it can be uniformly converted into a predetermined codec and stored.
