Description

Switching method for creating and managing call detail records {METHOD OF OPERATING AND ADMINISTRATING DETAILED RECORD OF A CALL HISTORY}

The present invention relates to a method for generating a call information record generated by a line connection between a caller and a called party in a telephone exchange. Particularly, a call history, statistical data, billing data, etc. are calculated quantitatively and accurately, A technique for recording call transitions, three-way calls, and the like in detail.

When a caller enters the called party's telephone number through a communication terminal such as a public telephone, a public telephone, or a mobile telephone, and requests the telephone exchange to make a telephone connection, the telephone exchange connects the caller's line and the called party's line to each other so that the call can It works to establish. At this time, the called party accepts the caller's call request and the mutual phone call is called 'call'. When the call is terminated and the line connected for the mutual phone call is disconnected, the call is lost.

By the way, the call is lost due to the disconnection of the circuit, but various kinds of historical information about the lost call are transmitted from the buffer memory of the telephone exchange to the service system which processes the statistical data. On the other hand, the call history information transmitted to the statistical data processing service system is processed in accordance with a predetermined format (store) in a storage location in the database.

The call history information stored as such is used as statistical data for the communication service provider to calculate various statistical information such as call time, origination area, reception rate, or billing data for billing the user with the provided service usage fee or service fee. Is used.

According to the method of generating call history information according to the prior art, while the call is generated through the communication line connection and the call is terminated by disconnection at the end of the telephone call, the history information for the call is accumulated in the buffer memory of the telephone exchange. The accumulated call history information is not accumulated due to the capacity limitation of the buffer memory, and is transmitted to the service system which processes statistical data at the same time as the call disappears.

The call history information transmitted to the statistical data processing service system according to the prior art is not an information record form having a systematic format and contents so that it can be directly applied to accurate statistics or a billing system, but the caller and called party's telephone number and telephone call time. And the like are checked and have a small simple recording form recorded in the buffer memory of the telephone exchange.

Therefore, call history information accumulated and transmitted in the buffer memory of the telephone exchange according to the prior art is subjected to a processing process in a service system for processing statistical data, and the information data generated through the processing is not generated. It is in the form of call history information that systematically includes detailed information about. As a result, call history information processed and generated in the statistical data processing service system is transferred to a database for storing and managing various information materials and stored according to a predetermined rule.

Techniques for methods and systems for generating history information of calls originating from telephone exchanges and storing and managing records of calls are detailed in US Pat. Nos. 5,898,762, 5,283,829, 5,220,501 and the like.

However, recently, as communication devices and systems and communication services provided are developed, functions of telephones are complicated and variously, services provided by telephony providers have tended to be diversified. In particular, as the demand for additional services for a call, such as a change in the state of a caller or a change in the number of callers, increases, the contents of call control are gradually complicated.

Accordingly, various call types such as call transition, call transfer, three-way call, call return, etc. in the telephone exchange can be made in order to satisfy the request of the additional service for the call. However, the method for generating and managing call history information according to the conventional technology has call history information generated by the telephone exchange in a small unit in a simple recording form in the buffer memory, and is accumulated in the statistical data processing service system at the same time as the call disappears. Call history information management has a problem that is very dependent on the service system that receives and processes the data from the buffer memory of the telephone exchange.

As a result, in the prior art, where the management of call details is dependent on the service system, it is impossible to calculate accurate telephone statistics for various additional services such as call transitions, call transfers, and three-way calls. There is a problem that it becomes difficult to operate a stable billing management.

That is, in order to generate accurate call history information, the telephone exchange should be able to independently manage call history information regardless of the service system. The method of generating and managing call history information according to the related art described above is provided for statistical data processing. Depending on the service system, there is a disadvantage that it is difficult to accurately track and calculate various form changes of the call within the telephone exchange.

Accordingly, the above-mentioned problem of the method for generating and managing call history information according to the prior art is solved, and a new operation method for managing call history information capable of independently generating call history information in a telephone exchange regardless of a service system is provided. New call history information management method to extract accurate and reliable statistics and billing data for various call types such as call transition, call transfer, three-way call, call return, etc. The system is indispensable.

Accordingly, a first object of the present invention is to provide a system operation method for generating a detailed record of a call using history information on a call generated at a telephone exchange independently regardless of a service system.

In addition to the first object, the second object of the present invention is to accurately track various call types such as call transitions, call transfers, three-way calls, call reversions, etc. in the telephone exchange, thereby providing reliable call history information. It is to provide a system operation method to generate.

The third object of the present invention, in addition to the first object, is to describe the history of the call generated in the telephone exchange without omission and transmit without loss to the database to generate call history information that can be used to calculate stable statistics and billing data. It is to provide a system operation method.

The present invention provides a method of operating a telephone exchange system that can independently record information on a history of a digital recorder and store or transmit it to a system other than a telephone exchange requiring a call detailed record (CDR).

In addition, in order to achieve another object of the present invention, in a logical call, call detail recording sequence, call ID (ID), original originating signal received from the network, original incoming signal received from the network, It manages the type of call inside the exchange, the start time of information creation of call detail record, and the end time of information generation of call detail record, and the line ID, occupancy start time, response time, recovery time, call in each circuit constituting the call. Provided is a method for operating a telephone exchange system that generates and manages call detail records including direction, calling line, directory number, and the like.

Best Mode for Carrying Out the Invention Preferred embodiments of a call detail record generation and operation system and method according to the present invention will now be described in detail with reference to the accompanying drawings.

Figure 1 illustrates a call information operation and management technique for storing and transmitting history information of a call generated at a telephone exchange in a call detail recording format by a line connection between a caller and a called party according to a preferred embodiment of the present invention. Referring to FIG. 1, a telephone exchange 110, a general telephone network 120, a caller 131, a called party 132, a call controller 140, a statistical data processing service system 150, a call information database 160, Statistical data system 170, billing data system 180, call detail record 210, and the like are shown.

Referring to FIG. 1, the caller 131 requests the telephone exchange 110 to make a telephone call with the called party 132 through the general telephone network 120, and if the line connection with the called party 132 is successful, the call exchanger ( An arc is generated at 110). The generated call is adjusted and managed by the call controller 140. The call history information generated during the telephone call is stored in the buffer memory in the telephone exchange 110.

When a call disappears due to a line disconnection between the caller 131 and the called party 132 according to the termination of a phone call, a detailed call record with a systematic format is used by using the history information of the destroyed call stored in the buffer memory in the telephone exchange 110. 210 is generated. The call detail record 210 generated according to the present invention is transmitted to the statistical data processing service system 150, and when the transmission to the statistical data processing service system 150 is completed, the call history information and the call detail record 210 are It is deleted from the buffer memory.

Meanwhile, the call detail record 210 transmitted to the statistical data processing service system 150 is transmitted to the call information database 160 and stored. Subsequently, the call history information stored in the call information database 160 according to the present invention is used for requesting information such as a statistical data system 170 for calculating various statistical data and trends and a billing data system 180 for calculating various usage charges. Are accessed and utilized accordingly.

FIG. 2 illustrates a workflow in which call history information generated in a telephone exchange and stored in a buffer memory is stored and transmitted in a call detail recording format according to a preferred embodiment of the present invention, and used as data for statistics or billing. Referring to Figure 2, in the system for generating the history information data of the call generated in the telephone exchange 110 when the telephone line connection between the caller 131 and the called party 132, the caller 131 is connected to the general telephone network 120 The telephone exchange 110 makes a call request with the called party 132 (step S300).

Subsequently, the telephone exchange 110 attempts to connect the telephone line between the called party 132 and the caller 131 according to the request of the caller 131 (step S301). However, when the line connection between the caller 131 and the called party 132 fails, the caller 131 transmits a busy signal and ends (step S302).

If the line connection is successful, a call is generated due to the line connection between the caller 131 and the called party 132 (step S303). Subsequently, after the call type is changed or the call disappears, the call detail record 210 is generated using the call history information stored in the buffer memory (step S304).

On the other hand, the call detail record 210 generated by the telephone exchange 110 is transmitted to the statistical data processing service system 150, and the call history information and the call detail record 210 accumulated in the buffer memory are deleted (step S305). ). Subsequently, the statistical data processing service system 150 transmits and stores the call detail record 210 to the call information database 160 (step S306). Finally, the call detail record 210 stored in the call information database 160 is accessed and utilized by the statistical data system 170 and the charging data system 180 (step S107).

Meanwhile, the history information 420 of the first call 510 and the detailed record 210 of the first call 510 are removed from the buffer memory of the telephone exchange 110.

Next, a new second call 520 is generated to connect the first caller 551 and the third caller 553. The history information 420 of the second call 520 reorganized in the first call 510 is accumulated in the buffer memory 410 of the telephone exchange 110. In the case where the call transition is realized by changing the form of the call generated by the telephone exchange through the adjustment of the call controller, the information of the line included in the first call 510 is determined by the first caller 551 constituting the first call 510. ) And the second caller 552, the information of the line included in the second call 520 is the first caller 551 and the third caller (553) constituting the second call (520) ).

At this time, the call recovery time for the first caller 551 is not recorded in the call detail record 210 of the first call, and the call detail record 210 of the first call is calculated when the billing information and the relay line statistics are calculated later. By recognizing that the call recovery time is not recorded, it may be confirmed that the first call 510 has a change in a call type such as a call transition. However, the line occupancy and response time for the first caller 551 recorded in the call detail record 210 of the second call is determined by the line occupation for the first caller 551 recorded in the call detail record of the first call and It has the same data as the response time.

5 illustrates a method in which a three-way call is realized by changing the form of a call generated at the telephone exchange according to a preferred embodiment of the present invention through adjustment of a call controller. Referring to FIG. 5, the first call 510 connecting the first caller 551 and the second caller 552 connects the first caller 551 with the third caller 553. In the second call 520, the first call 510, which connects the first caller 551 and the second caller 552, is extinguished for the third party call.

Subsequently, the detailed record 210 of the first call 510 is generated using the history information 420 of the first call 510 stored in the buffer memory 410 of the telephone exchange 110, and the telephone exchange The detailed record 210 of the first call 510 generated at 110 is transmitted to the statistical processing service system 150. Meanwhile, the history information 420 of the first call 510 and the detailed record 210 of the first call 510 are removed from the buffer memory 410 of the telephone exchange 110.

In addition, the second call 520 connecting the first caller 551 and the third caller 553 is extinguished. Subsequently, the detailed record 210 of the second call 520 is generated using the history information 420 of the second call 520 stored in the buffer memory 410 of the telephone exchange 110, and the telephone call is generated. The detailed record 210 of the second call 520 generated at the exchange 110 is transmitted to the statistical processing service system 150. Meanwhile, the history information 420 of the second call 520 and the detailed record 210 of the second call 520 that are accumulated in the buffer memory 410 of the telephone exchange 110 are removed.

Subsequently, a new third call 530 is generated to connect all of the first caller 551, the second caller 552, and the third caller 553. The history information 420 of the third call 530 reorganized in the first call 510 and the second call 520 is stored in the buffer memory 410 of the telephone exchange 110.

Since the form of the call generated in the telephone exchange is changed through the adjustment of the call controller, and the three-way call is realized, the information of the line included in the first call 510 is determined by the first caller (that constitutes the first call 510). 551 and the second caller 552, and the information on the line included in the second call 520 includes the first caller 551 and the third caller constituting the second call 520 ( 553). In addition, the information on the line included in the third call 530 intervenes in the generation of the second caller 552, the third caller 553, and the third call 530 constituting the third call 530. It consists of information about the first caller (551).

At this time, the call recovery time for the second caller 552 is not recorded in the call detail record 210 of the first call and the call recovery time for the third caller 553 in the call detail record 210 of the second call. The time is not recorded. When calculating the billing information and the relay line statistics later, the call detail record 210 of the first call 510 and the second call 520 is used for the second caller 552 and the third caller 553, respectively. Recognizing that the call recovery time is not recorded, it may be confirmed that the first call 510 and the second call 520 have a change in the call type such as a three-way call.

However, the line occupancy and response time for the first caller 551, the second caller 552, and the third caller 553 recorded in the call detail record 210 of the third call is determined by the first call and the second call. It has the same data as line occupancy and response time for the first caller 551, the second caller 552, and the third caller 553 recorded in the call detail record of the second call.

Fig. 6 illustrates a method in which a call return is realized by changing the form of a call generated at the telephone exchange according to a preferred embodiment of the present invention through adjustment of a call controller. Referring to FIG. 6, in the first call 510 connecting the first caller 551 and the second caller 552, the first caller 551 and the third caller are once used to realize call return. Create a second call (520) connecting the caller (553).

Subsequently, while attempting to connect the first caller 551 and the third caller 553 through the second call 520, the line connection between the first caller 551 and the third caller 553 is not established. Failed to cancel the connection. The second call 520 connecting the first caller 551 and the third caller 553 is extinguished.

Meanwhile, the detailed record 210 of the second call 520 is generated using the history information 420 of the second call 520 stored in the buffer memory 410 of the telephone exchange 110, and the telephone call is generated. The detailed record 210 of the second call 520 generated at the exchange 110 is transmitted to the statistical processing service system 150. Then, the history information 420 of the second call 520 and the detailed record 210 of the second call 520 that are accumulated in the buffer memory 410 of the telephone exchange 110 are removed.

Then, the call returns to the first call 510 connecting the first caller 551 and the second caller 552. The returned history information 420 of the first call 510 is accumulated in the buffer memory 410 of the telephone exchange 110.
