BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exchange system, and more particularly to a call processing operation test system in the exchange system.

[0002]

2. Description of the Related Art Generally, in a premises in which a plurality of communication terminals (telephones) are installed, there is used an exchange which controls connections between extensions and makes and receives calls between the inside and the outside.
This exchange is a terminal interface that accommodates a plurality of communication terminals (telephones), a line interface that connects to a station line / dedicated line, a switch unit (connection unit) that performs a call path exchange connection, and call exchange control. It is composed of a control unit for performing processing, and the operation of each unit for making and receiving calls is controlled by the exchange software.

[0003] Conventionally, when debugging exchange software, on a general-purpose control device such as a workstation or a personal computer, terminal control means that virtualizes the function of the exchange-specific device and the operation of a communication terminal are simulated. A terminal simulator to reproduce was provided, and the call processing operation was confirmed using this terminal simulator. Here, the exchange-specific device refers to a hardware portion obtained by removing the control unit from the above-described components of the exchange.

In this case, the function corresponding to the control unit is
It is realized by the exchange control means set on the general-purpose control device. However, in the test of call processing operations such as call origination / termination performed by using the exchange control means, the terminal control means, and the terminal simulator, the contents of signals going in and out between communication terminals are logically judged. The success or failure is confirmed, and the actual communication path of the communication terminal is not controlled or the communication is not performed. Therefore, finally, the call processing operation is confirmed again by using the actual hardware.

[0005]

As described above, in the conventional method, after the debugging using the terminal control means or the like on the general-purpose control device, the procedure is further shifted to the test using the actual exchange. I had to. However, when the type and number of line interface cards and the number of slots for accommodating the line interface cards in the actual exchange are limited, that is, when the hardware environment is limited, the data used for the test is the terminal control means. It has to be rebuilt for the actual exchange from the one used in the simulation, and in addition to the time to move the test environment, it is also necessary to rebuild the test data, so it takes time and effort. There was a problem.

As described above, in the conventional switch software development environment, complicated work such as software debugging and testing is required. Therefore, it is not possible to realize new service development in a short period of time in response to various user needs. It was difficult, and the work efficiency was required.

An object of the present invention is to provide an exchange system capable of efficiently developing software by simplifying the work for confirming the operation of call processing.

FIG. 4 is a layout diagram of a communication terminal connected to the exchange-specific device 14 and the terminal control means 12. The terminal I / F of the exchange specific device 14 accommodates a plurality of communication terminals such as a standard telephone 14a and a digital telephone 14b, and the terminal I / F section of the terminal control means 12 is a pseudo communication terminal. The simulator 12a is housed. It should be noted that the accommodation position of the connected communication terminal, the setting of the slot number, and the like correspond to the table of FIG.

Next, the processing procedure for testing the call processing operation in the above-mentioned exchange system 100 will be described with reference to the flowchart of FIG.

When testing the call processing operation for the communication terminal connected to the exchange specific device 14, a signal is input to the communication control means 13 by the terminal simulator connected to the terminal control means 12. In this way, the call origination process is carried out by the terminal simulator connected to the terminal control means 12.

The signal interface 21 in the communication control means 13 relays the request signal received from the terminal control means 12 to the communication control section 24, and the communication control section 24 exchanges with the exchange control means 1.
The request signal is passed to 1 (step 101). The exchange control means 11 carries out an actual exchange control process according to the request signal,
Based on this result, a response signal is returned to the communication control unit 24 (step 102). The communication control unit 24 passes this response signal to the signal analysis unit 22. The signal analysis unit 22 analyzes the response signal, extracts the information such as the terminal number and the terminal attribute, and passes the information to the communication control unit 24 (step 103).
The communication control unit 24 activates the connection destination information storage unit 23,
The table is searched based on the terminal number and the terminal attribute, and the information regarding the connection destination is acquired (step 104). From this information, the communication control unit 24 confirms the setting of the connection destination mode and the mounting state of the exchange-specific device 14 (step 10).
5). Then, the communication control means 24 determines the exchange-specific device 14 or the terminal control means 12 to which the call is connected (step 106), and based on the determination result, connects to both the exchange-specific device 14 and the terminal control means 12. A request signal is sent (step 107).

Next, a specific example of the case where the call processing operation is tested based on the processing of the above-mentioned flowchart will be described with reference to FIGS.

First, when the standard telephone 14a at the accommodation position "00" and the slot "01" in the exchange-specific device 14 makes a call to the digital telephone 14b at the same accommodation position and the slot "02", the terminal control is performed. Means 1
A signal is input to the communication control means 13 using the terminal simulator 12a connected to 2. In the communication control means 13, a signal is passed to the communication control section 24 through the signal interface 21, and the exchange control means 11 executes the actual exchange control processing. The response signal from the exchange control means 11 is analyzed by the signal analysis section 22, and information such as the terminal number and the terminal attribute is taken out. In the connection destination information storage unit 23, the table is searched based on the terminal number and the terminal attribute passed from the communication control unit 24, and the information regarding the connection destination is extracted.
As a result, it is possible to know that the connection destination mode of the digital telephone 14b, which is the connection destination, is both the exchange-specific device 14 and the terminal control means 12, and the implementation of the communication terminal in the exchange-specific device 14 by the terminal control classification. You can check the status. The communication control unit 24 sends a connection request signal to both the exchange-specific device 14 and the terminal control means 12, which are connection destinations. Also, the standard telephone 1 that is the caller
Since the connection destination mode of 4a is only the exchange-specific device 14, the connection request signal is transmitted only to the exchange-specific device 14. As a result, the standard telephone set 14a connected to the exchange-specific device 14 hears the ringing tone, and the digital telephone set 14b rings. On the other hand, a message indicating an incoming call is displayed on the digital telephone 14b in the accommodation position "00" and the slot "02" on the terminal simulator connected to the terminal control means 12.

Next, in the exchange-specific device 14, the digital telephone set 14b having the accommodation position of "00" and the slot of "02".
From now on, a case will be described in which a calling process is performed to the digital telephone set at the accommodation position “02” and the slot “01”.
Also in this case, a signal is input to the communication control means 13 using the terminal simulator 12a connected to the terminal control means 12. Similar to the previous example, the exchange control means 11 executes the actual exchange control processing on the input signal from the terminal simulator 12a, the response signal is analyzed by the signal analysis unit 22, and information such as the terminal number and the terminal attribute is obtained. Is taken out. Then, in the connection destination information storage unit 23, a table is searched based on these terminal numbers and terminal attributes, and information regarding the connection destination is extracted. As a result, the connection destination mode of the digital telephone as the connection destination is set to the exchange-specific device 14 and the terminal control means 12.
You can know that both are. On the other hand, looking at the terminal control section, the communication terminal of the connection destination is the exchange-specific device 14
It can be confirmed that it is not implemented in. In this case, the communication control unit 24 sends the connection request signal only to the terminal control unit 12. Also, the digital telephone 1 that is the sender
Since the connection destination mode of 4b is the exchange-specific device 14 and the terminal control means 12, the connection request signal is sent to both the exchange-specific device 14 and the terminal control means 12.
As a result, the digital telephone 14b connected to the exchange-specific device 14 hears the ringing tone, and the terminal control means 1
The digital telephone 14 in the accommodation position "02" and the slot "01" on the terminal simulator 12a connected to
A message indicating an incoming call is displayed on b.
If a voice interface is installed on the terminal simulator 12a, the same ring tone as that of an actual digital telephone can be heard.

In this example, the digital telephone, which is the communication terminal of the connection destination, is not mounted in the exchange-specific device 14, but since it can be simulated by the terminal simulator 12a on the terminal control means 12, the test data can be obtained. Is used in the terminal simulator 12a on the terminal control means 12, there is no need to newly reconstruct it for an actual exchange.

[0033]

As described above, in the exchange system according to the present invention, the communication control means for determining the connection destination of the call based on the connection destination information of the incoming call is provided, and the transmission from the communication terminal is prevented. Since the call is connected to the terminal control means and the exchange specific device through the communication control means, the call processing operation is tested to the exchange specific device almost at the same time as the terminal control means on the general-purpose control device performs the test. Can also be implemented. According to this, the exchange-specific device and the terminal control means can coexist in one system. Therefore, after debugging is performed by using the terminal control means or the like on the general-purpose control device as in the conventional case, the actual exchange can be operated. Since the work of shifting to the test used is not necessary and the restrictions of the hardware environment of the actual exchange can be absorbed by the terminal simulator on the terminal control means, it is necessary to reconstruct the test data for the actual exchange. Data can be used effectively.

As described above, in the exchange system according to the present invention, complicated work such as software debugging and testing can be simplified, so that software development can be efficiently performed. Therefore, when developing a new service for the exchange software, it is possible to realize a new service development in a short period of time in response to various user needs.

The call connection of various communication terminals connected to the exchange-specific device can be controlled by the terminal control means set on the general-purpose control device such as a workstation. By controlling the switching processing of the communication path that is being performed, supporting voice interface, etc., it is possible to realize an application such as an automatic telephone call.
