Hereinafter, an operation according to an exemplary embodiment of the present invention will be described in detail with reference to the above configuration.

Meanwhile, in the following description of an operation according to an exemplary embodiment of the present invention, an operation of updating the operation information required by the exchange to transmit information through the D channel of the ISDN and an operation of actually transmitting the information are described. Explain them separately.

First, with reference to the control flow shown in Figure 2 will be described in detail a preferred embodiment according to the operation of updating the operation information required by the exchange to transmit information through the D channel of the ISDN in detail.

The central processing unit 110 monitors whether there is an input of a secret code in step 210 to control the authority to access maintenance, statistics, and billing information. In step 210, when the password for which the use right is recognized is input, the central processing unit 110 proceeds to step 212. In step 212, the central processing unit 110 switches to an environment setting mode in which operation information according to the present invention can be set by an operator.

When the switch to the environment setting mode is made, the CPU 110 proceeds to step 214 to determine whether a service change request is input from the operator to change the operation information according to the present invention.

If the password is not input in step 210 or the service change request according to the present invention is not input in step 214, the central processing unit 110 proceeds to step 224 to perform a corresponding function.

In contrast, when a service change request according to the present invention is input, the CPU 110 proceeds to step 216 to access a database storing maintenance, statistics, and billing information.

When the connection to the database is made, the CPU 110 proceeds to step 216 to perform service registration according to a menu of operation information according to the present invention.

Looking at this in more detail, the central processing unit 110 provides the operator with a message asking the type of maintenance, statistics and billing information, and determines the information type by the operation information provided from the operator in response to the question Save it. When the storage of the information type is made, the central processing unit 110 asks for a period to transmit, and stores the information provided from the operator as a period in response to the question. By the above method, additional operation information is received from the operator and stored.

While the service registration is performed by the routine as described above, the CPU 110 checks whether the service registration termination request is made from the operator in step 220.

If the service registration termination request is detected in step 220, the CPU 110 proceeds to step 222 and completes the service registration, and then performs the information providing operation according to the present invention by the registered operation information.

Next, the operation of transmitting information through the D channel of the ISDN by the operation information updated by the above operation will be described.

The central processing unit 110 monitors whether a message is received from the private exchange through the D channel configured as the SO 136 in step 310. When the reception of the message is detected in step 310, the CPU 110 determines whether the received message is a call control message or maintenance, statistics, and billing information in steps 312 to 316.

In step 312, it is determined whether the received message is a call-related message. In step 314, it is determined whether the received message is a control / management message. In step 316, it is determined whether the received message is a message including statistics / billing information.

If it is determined in step 312 that it is a call-related message, the ISDN terminal 138 proceeds to step 328 and performs a D channel control processing routine that is normally performed through the D channel of the ISDN, and ends.

However, if the control / management message is determined in step 314, steps 318 to 322 are performed. If it is determined in step 316 as a statistics / billing message, steps 324 to 326 are performed.

First, in the case where the control / management message is determined in step 314, the ISDN terminal 138 proceeds to step 318 and analyzes the control / management information from the received message. When the analysis of the control / management information is completed, the ISDN terminal 138 proceeds to step 320 and performs response processing corresponding to the analyzed control / management information, and then proceeds to step 322. The ISDN terminal 138 proceeds to step 322 and provides information to the operator by displaying the processing result made in step 320 on the monitor.

Secondly, in the case where it is determined in step 316 that the statistics / charging message, the ISDN terminal 138 proceeds to step 324 to analyze the statistics / charging information from the received message. Meanwhile, when the analysis is performed, the ISDN terminal 138 configures and stores the analyzed statistics / billing information in an internal memory. When the storage is completed, the ISDN terminal 138 proceeds to step 326 to notify the operator of the result by displaying the stored result on the monitor.

As described above with reference to FIG. 3, when the maintenance, statistics, and billing information are input from the side of the ISDN terminal 138 connected to the SO 136, firstly, whether the information is control / management information. Separate If it is a control / management message, the corresponding processing and response is sent. In addition, in the case of statistics / billing information, it is checked whether or not it is a real-time display designation state, and the screen is displayed and stored to update the database. The information stored in this way can have a separate database structure for processing if necessary.

As described above, the present invention generally avoids the limited use of the ISDN service mainly used for voice and data communication on the B channel, and can be referred to as a method that can utilize the ISDN network more efficiently.

As the conventional limited service alone does not make the most of the advantages of the ISDN and does not sufficiently show the advantages of the ISDN to the user, the text information service according to the present invention can provide various additional services in its application. This can increase the value of the system and increase the utilization of ISDN.

In addition, by integrating the configuration of devices for maintenance, statistics, and billing in a single structure, the cost of implementation can be minimized because additional hardware is not required, and the further improvement of services is easy. Has an advantage.
