Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a test verification method associated with a change in station / subscriber conditions during maintenance and operation of an electronic exchange.

[Conventional technology]

For the conventional test verification method, either one of the following two methods or a combination thereof was adopted. (B) In the case where the station / subscriber condition description data of the current operation is changed in advance and the changed data is referred to as normal processing without burdening the reference program, and the correct result is obtained. Recognizes this change as a formal process, but if an erroneous result is obtained due to this change, further change it and perform the test and verification again. (B) For limited station / subscriber condition description data, such as route decision data for incoming calls from the electronic exchange, two types of data are prepared in advance, one for current operation and one for test verification, and the reference program Also, set up a processing group that refers to each for current operation or test verification,
The data for test verification is referred to during test verification, and if this produces a correct result, the data for test verification is adopted as the data for the current operation, but if the reference produces an incorrect result, further Change the test verification data and repeat the changes until correct results are obtained.

[Problems to be Solved by the Invention]

In the above-mentioned conventional test verification method (a), the change data is temporarily overwritten on the change target data, that is, the current operation data, and the reference program refers to the change data by the same processing as the reference of the current operation data. To do. Therefore, when accidental failures occur during test verification, such as failure of the main processing unit and recovery from the failure, the change target data, that is, the current operation data is guaranteed by the program and data initial load, but the change data itself is lost. .

Further, in the conventional test verification method (b), if the current operation data and the changed data are located on the same main processing unit, the problem in the test verification method (b) is still taken over, and if not, When the current operation data and the changed data are located on different main processors, this time, two types of programs, one for the current operation and one for the test verification, are provided for each test verification type, and thus for each reference program to the target data. It had to be developed and prepared, and the number of information elements was increased due to the necessity of introducing an identifier for identifying the main processing unit on which both data are mounted.

Therefore, according to the present invention, when the station condition description data is changed and tested and verified, the arrival and the reference to the current operation data and the change data are carried out by completely different programs, and the main processor for referring to the change data. It is to provide the system with fault tolerance of changed data and simplification of reference processing by arranging it on a processing device separate from that and achieving it by the method of the present invention.

[Means for solving the problem]

The test verification method of the present invention refers to the current operation data or changed data of the station / subscriber data in a program group for realizing the test verification accompanying the change of the station / subscriber data of the electronic exchange. A call processing program and a station / subscriber data management program for delivering the current operation data or the changed data to the call processing program in response to a reference request from the call processing program are arranged in the call processing device,
A copy of the subscriber data management program and test verification data as the change data are arranged in the maintenance operation management processing device, and an interface for issuing a reference request from the call processing program is used as a station / subscriber data management program of the call processing device. The station / subscriber data management program of the call processing device issues a reference request to the station / subscriber data management program of the maintenance operation management processing device in response to the request for reference of the test verification data from the call processing program. Then, the station / subscriber data management program of the maintenance operation management processor refers to the test verification data and returns a reference result to the station / subscriber data management program of the call processor.

[Action]

According to the present invention, when the station / subscriber data of the electronic exchange is changed, the station / subscriber data reference program, a so-called call processing program, is not added to the data for the current operation on the processor. The change processing data is generated on the maintenance operation management processing device without any change, and when the test call which is the purpose of the test verification is generated, the call processing program generates the test verification data reference request, and this request The subscriber data management program carries the data to the maintenance and operation management processing unit, and the above request is realized only for maintenance and operation management. That is,
The substance of the test verification data is referred to, the test verification data reference result is returned to the request source processing device, and the reference request generation source program of this device can refer to the test verification data as the request result.

〔Example〕

Next, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a diagram showing the system and software configurations of an embodiment of the present invention. In this system, a call processing device 1 accommodating an exchange subscriber 4 is connected to a maintenance operation management processing device 2 via a system internal bus 5. The processing device 2 has the external storage device 3 as a storage medium. Further, the call processing program, that is, the station / subscriber data reference program A processes a series of exchange operations such as call generation and call disconnection from the subscriber 4 while referring to the station / subscriber data C. The data reference request a is issued to the station / subscriber data management program B on the processor 1, the program B directly refers to the data C, and the reference result b is returned to the program A. FIG. 2 shows the flow of call handling processing in the above-mentioned normal processing. Further, the same program B as the program B in the call processing apparatus 1 is installed in the processing apparatus 2 in FIG. 2, and the station / subscriber data is changed in the external storage apparatus 3, that is, the test verification. Data is installed, but these are not activated or referenced at all in normal call processing.

FIG. 3 shows the flow of software processing at the time of test verification. The data C'in the external storage device 3 is test verification data generated by the switching center maintenance person via the switching center maintenance operation command. is there. The program A issues a request a'instead of the request a to the program B, and as soon as the program B recognizes that the request is a ', it immediately sends this request to the same program B in the maintenance operation management processor 2. Forward. The program B in the processing device 2 recognizes that the requested data C'is installed in the external storage device 3 connected to the own processing device 2, and refers to the data C'to request the result. The same program B in the call processing device 1
Return to. The program B in the call processing device 1 returns the returned result to the program A as the final request source as the result b '.

The request a and the request a ′ have exactly the same format,
The only difference is that the requirements themselves are different. The program B in the call processing device 1 is open to the same format for all the station / subscriber data reference programs, and the user of the program B is not limited to the program A shown in the figure.

〔The invention's effect〕

As described above, according to the present invention, the test verification data at the time of maintenance operation work is completely separated from the call processing device that is the center of the exchange processing in the electronic exchange, and the fault tolerance function of the call processing device is converted to the test verification function. Along with expansion, it provides a format in which all stations / subscriber data reference programs, that is, call processing programs, can refer to test verification data in exactly the same format when the current operation data is referred to. The development and maintenance of the subscriber data reference program can be facilitated.
