Abstract

A call control management system is constructed causing no deterioration in performance relative to call control even when utilizing a totalizing function. The call control management system includes a call control system and a call information management system. The call control system outputs, every time the transition of a status of a call under control is made, a record showing a status after the call transition to a call status information log file. The call information management system extracts a record about the same call from the call status information log file, creates a record containing at least data convertible into a call charge on the basis of the extracted record, and stores the call information collecting log file with the created record. The call information management system, when indicated to output accounting information and traffic information etc, creates and outputs information indicated to be outputted based on the information stored in the call information collecting log file.

Claims

1. A call control management system for performing communications via a telephone line network, comprising:

a call control unit having a call status information log file for storing a call status record of each call showing a certain call status at a certain time, for implementing call control and outputting the call status record showing a status after a call transition to said call status information log file every time when the call status transition is made; and

a call information management unit extracting the call status record relative to the same call from said call status information log file, creating a call information record containing at least a data which is convertible into a call charge on the basis of the extracted call status record, and storing the created call information record in the form of a report call information log file to reduce the load on the call status information log file.

2. A call control management system according to claim 1, wherein said call control unit allocates a unique call identification data to a new call when starting the control relative to the new call, indicates a status after the call transition each time when the call status transition is made, and outputs the call status record containing the call identification data allocated to the call to said call status information log file;

and

said call information management unit extracts the call status record pertaining to the same call from said call status information log file by use of the call identification data.

3. A call control management system according to claim 2, wherein said call information management unit extracts only the call status record needed for creating the call information record relating to the same call from said call status information log file.

4. A call control management system according to claim 1, wherein said call information management unit creates the call information record in said report call information log file which allows summing up of an accounting information and a traffic information, respectively, and outputs, upon indicated to output the accounting information or the traffic information, the call information record stored in the report call information log file showing a result of sum of the basis of the indication.

5. A call control management system according to claim 1, further comprising:

an application unit for controlling said call control unit in order to implement a service of connecting said telephone line network to a computer, said application unit having an application information log file for storing a record showing a content of the service implemented, and storing said application information log file with the record showing the content of the service when starting the service; and

wherein said call information management unit, upon indicated to output information based on a service unit, outputs information relating to a designated service by combining the record stored in said application information log file with the call information record stored in the report call information log file.
