[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a call management system for a digital exchange that edits detailed call record information.

[0002]

2. Description of the Related Art In a conventional digital exchange system, a call management system is connected online as an external device of a digital private branch exchange. When the call ends, this digital private branch exchange collects detailed record information such as the caller number, the other party's number, the call start time and the call time for the call, and transmits it to the call management system.

In the call management system, the call charge for the call is calculated based on the received detailed record information, and in the case of the calling terminal unit, in the case of a business office, the section, department,
The data is collected for each business site, recorded on memory, and output to a printer.

As described above, in the conventional call management system,
The main purpose was to charge and manage calls made through digital exchanges, but since detailed information can be collected for each call, various usage methods are possible,
For example, there has been a demand for collecting statistics on the usage status of transfers and conference calls, and effectively utilizing them for increasing / decreasing equipment and improving numbering plans.

In the conventional collection of detailed record information, each detailed record information corresponding to a call path of a two-way call is created,
In the case of transfer, each detailed record information is created corresponding to the call path of each two-way call before and after the transfer, and when further transferred, the detailed record information is created again. ing.

For example, as shown in FIG. 7, the digital private branch exchange 24 has terminals 24a, 24b, 24 such as telephones.
In a digital exchange system in which c is connected,
When the terminal 24a calls the terminal 24b through the digital private branch exchange 24 and the terminal 24b calls and transfers the terminal 24c, the detailed record information 25 and 24b-24c for the call between 24a and 24b before the transfer Three pieces of detailed record information, that is, the detailed record information 26 corresponding to the intervals and the detail record information 27 between 24a and 24c after the transfer are all created in the digital private branch exchange 24, and 24a-24b.
The detailed record information 25 for the interval and the detailed record information 26 for the interval 24b-24c are transmitted to a call management system (not shown) when the terminal 24b transfers and exits, and
The detailed record information 27 for -24c is transmitted to a call management system (not shown) when the call ends.

FIG. 8 shows an output example of a call statement when a charge is calculated by a call management system (not shown) based on the detailed record information and is immediately printed out as call statement information. In FIG. 8A, from the terminal 24a with the extension number 4000 to the outside line (03-1234567) at 9:00.
Shows an example in which a call is made to and the call ends for 3 minutes.

In FIG. 8B, the terminal device 24a with the extension number 4000 calls the terminal device 24b with the extension number 5000,
This is the case where the terminal 24b calls and transfers the outside line (03-1234567). The first two call details are output at the time of transfer, and the third call details are after transfer 24a-2.
It is output at the end of the call between 4c. FIG. 8C shows a case where the call details of another call are recorded in the call statement after the terminal 24b in FIG. 8B calls the terminal 24c.

As described above, in the conventional call management system,
It is not possible to distinguish between the detailed record information of the call that was ended by only two parties for one call and the detailed record information of the call that involved more than three parties (three or more terminals) such as transfer or conference call. Therefore, as shown in FIG. 8B, the extension number 5000 and the outside line (03-1234567) are transmitted even though the terminal 24a having the extension number 4000 makes a call only once.
It will be recorded in the call statement as if you made two calls to.

Further, when detailed record information of a plurality of calls involving three or more parties is output, such as transfer, as shown in FIG. 8 (c), a large number are output between the call details before and after transfer. When the call details are output, it is difficult to identify the relationship between them, and if you try to make effective use of transfer and conference call usage statistics to increase / decrease equipment or make a number plan, the printed call details There was a problem that you could not use it as it was.

[0011]

As described above, in the call management system in the conventional digital exchange system, the detailed record information of the call ended by only two parties for one call and the transfer or conference call can be performed. Since it is not possible to distinguish from the plurality of detailed record information of the calls involved in three or more parties, it is not possible to total the number of transfers, charges, time, and the like. Further, a call statement that outputs detailed record information relating to calls of three or more parties, such as transfer and conference call, has a problem in that it is difficult to identify their mutual relationship.

[0012] Therefore, an object of the present invention is to provide a call management system for a digital exchange, which can be effectively used for adding / decreasing facilities, improving number plans, etc. by collecting statistics of transfer and conference calls.
