Description

Exchange simulation method using OMS and its system {THE EXCHANGE SIMULATION METHOD USING THE OMS AND THEREOF SYSTEM}

The present invention relates to a method for simulating an interface module test using an OPERATION MAINTENANCE SYSTEM (OMS), and more particularly, to a method for simulating a developed block and an undeveloped block using an interface module. will be.

In general, in order to form a transmission path between two persons or more persons who send and receive pseudo information and data information, the connection request from the incoming line of the switch network is detected, the outgoing line is selected, and the incoming / outgoing line is established. A series of actions that monitor, cut, or charge a condition. The device that does this is called an exchange.

When the exchange is classified according to the format of the communication information, the voice format such as conversation is called the telephone exchange, the text format such as the full text is called the telegraph exchange, and the image information format is called the image exchange. In addition, information format suitable for machine processing, including telegraph exchange and image exchange, is called data exchange. On the other hand, if the subject of communication is heeded, it is classified into domestic public exchange, international exchange, premises exchange, and leased line exchange. The purpose of the exchange is to provide the means of information transfer and the efficient operation of the circuit.

When developing a single feature, the feature is tested at each stage of development, and the development proceeds to the next stage after testing is complete.

In general, simulation tests are divided into module test, integrated test, and system test.

The module test is conducted on a personal PC based on input / output, and the integrated test is a step of testing interfaces or block relationships between developers.

The system test verifies the operation state between the blocks of the sub-system or higher concept, and is recognized as the final test according to the function implementation.

The integrated test and the system test are verification steps for testing whether the software developed while the hardware is operating normally operates correctly.

The system test is a step for checking whether the corresponding function actually works by describing the operation sequence used by the customer in advance in the test procedure.

Figure 1 is a block diagram showing such a prior art.

The developer clearly presents the interface relationship between different blocks to create a functional design document, and implements the functional design based on the written functional design document. Most tests are performed using the personal PC 10.

The test for the module is performed by a computer using input / output tests. To this end, the developer conducts module tests by using a macro method provided by various emulators or by using a separate program.

The interface test between different blocks manually writes system messages from other blocks on the PC, and the written messages are used as input messages to the development block.

Development S / S that simulates data processed by the input / output processing unit 21 for processing data input from the outside, the message processing unit 22 for processing the data input through the input / output processing unit 21, and the message processing unit 22. It is composed of a PC (10) that is connected to the switch system 20 consisting of the W block 23 and the relative development S / W / block 25 and the wired 30 to process the module test.

However, when performing a simulation using a PC as described above, there is a problem that the error occurs in the result because there is a difference from the test environment based on the system hardware.

Thus, a problem arises in that the reliability of the test data is lowered.

The present invention devised to solve the above problems, an object of the present invention is to simulate the interface module test between the developed software block and the undeveloped block using OMS.
