The simulator structure for the present invention includes a test control block 400, a basic call instance management block 500, a signal network matching unit primitive processing block 600, and a special resource service matching unit primitive processing block 700. It consists of two software blocks, two data files containing input data 650 and test output data 660 for testing.

Looking at each configuration and operation of the simulator in detail as follows.

The test control block 400 outputs a screen for selecting a test method to the tester, and receives a test method from the tester. The simulator of the present invention provides an automatic test for collectively performing test items without the tester's intervention and a manual test function for collecting the desired test items from the tester and performing the corresponding test procedure. If the tester wants the automatic test, the test start information is input and the corresponding test procedure of the basic call instance management block 500, the signal network matching unit primitive processing block 600, and the special resource service matching unit primitive processing block 700 is received. Is performed. If the tester wants a manual test, the test items are collected from the tester and the corresponding test of the basic call instance management block 500, the signal network matching unit primitive processing block 600, and the special resource service matching unit primitive processing block 700 is performed. Perform the procedure.

The basic call instance management block 500 is a block that replaces the role of the IUPC. The basic call instance management block 500 generates a basic call instance according to the instruction of the test control block 400, returns an instance identifier ProcessID, and sends a message from the BRSC 312. Receives a response message of the IUPC (314) and transmits to the BRSC (312).

The signal network matching unit primitive processing block 600 is a block that replaces the role of the signal network matching unit 313 illustrated in FIG. 1, and the network matching unit for each test item is instructed by the test control block 400. The primitive is generated and transmitted to the BRSC 312, and when a response message is received from the BRSC, the output result is compared to determine whether the test is successful.

The special resource service matching unit primitive processing block 700 replaces the roles of the special resource service matching units (SRSI) 321 and 331. The special resource service matching unit primitive processing block 700 performs a function module for each test item according to the test control block 400. In response to receiving the message from the BRSC 312, a response message of the SRSI 321 and 331 is generated and transmitted to the BRSC 312.

The test input data 650 is a file holding values that the signal network matching unit 313, the IUPC 314, and the SRSI 321, 331 should transmit to the BRSC 312 for the progress of all test items. The test output data 660 is a file holding true values that the BRSC 312 should output when proceeding with all test items.

When the test control block 400 outputs a screen for selecting a test method (401) to the tester, the tester inputs the automatic test and the manual test (402, 403). If the automatic test is selected, the test control block outputs a screen for selecting a start test item (404), and collects the test item (405) from the tester. According to the collected test item, the operation is requested (406, 407, 408) for the basic call instance management block, the signal network matching unit primitive processing block, and the special resource service matching unit primitive processing block. Since the test items collected from the examiner continue to proceed to the last test item, the signal matching part primitive processing block outputs the test procedure execution result on the screen (409). Proceed to the next test item sequentially until (410, 411).

However, when the tester selects the manual test, the test control block outputs a screen for selecting a desired test item (412) and collects the test item (413) from the tester. According to the test items collected from the tester, a request for performing operations to the basic call instance management block, the signal network matching unit primitive processing block, and the special resource service matching unit primitive processing block is requested (414, 415, 416).

When instructed to perform an operation from the test control block 400, a child process generating a call instance according to the received test item is generated 511, and ProcessID is transmitted to the signal matching unit primitive processing block 600. Forward 512 and wait to receive a message from the BRSC 312. Receiving a message from the BRSC (513), the test output data file 660 is used to compare whether it is a correct output value that can be generated in the test item (514). If the output is correct, the test input data file 650 can be used to generate (515) an IUPC message that can proceed with the test procedure, send it to the BRSC (516), confirm that it is the last test procedure (517), and finally Then terminates the child process and waits to receive a message from BRSC if not last. If the message received from the BRSC in step 513 is not the correct output value, the network matching unit primitive processing block 600 reports (518) that an error has occurred in the BRSC functional test in the corresponding test item.

FIG. 5 shows a procedure diagram of the BRSC test simulator signal network matching unit primitive processing block 600.

If the test control block 400 is instructed to perform the operation, the function module for each test item is performed. Upon receiving (611) a ProcessID, which is a basic call instance identifier capable of processing a corresponding test item, from the basic call instance management block 500, a signal network matching that can proceed with a test procedure using the test input data file 650. A secondary message is generated 612 and sent 613 to the BRSC, and waits for a response message to be received. Receiving a message from the BRSC (614), the test output data file 660 is used to compare whether it is a correct output value that can be generated in the test item (615). If it is a correct output value, check whether it is the end of the test procedure (617). If it is the last time, output to the tester 618 that the BRSC function test was successfully completed in the test item, and terminate the test procedure. In addition, when the message received from the BRSC in step 614 is not a correct output value, or an error occurs in the BRSC function test in the corresponding test item from the basic call instance management block or the special resource service matching unit primitive processing block (619, 620), when the test item receives an error in the BRSC function test, the tester outputs (616) and terminates the test procedure.

6 shows a flowchart of the execution of the BRSC test simulator special resource service matching unit primitive processing block 700.

If the test control block 400 is instructed to perform the operation, the function module for each test item is performed. Upon receiving a message from the BRSC (711), the test output data file 660 is used to compare whether it is a correct output value that can be generated in the test item (712). If the output value is correct, a test input data file 650 is used to generate (714) an SRSI message for advancing the test procedure, send it to the BRSC (715), and check whether it is the end of the test procedure (716), If it is the last time, the test procedure is terminated. If not, wait to receive a message from the BRSC. If the message received from the BRSC in step 712 is not a correct output value, the signal matching unit primitive processing block 600 reports (713) that an error occurs in the BRSC function test in the corresponding test item.

The present invention as described above is an implementation method of a test simulator that can verify the BRSC function mounted on the IP. Instead of acting as a signal network matching unit, IUPC and SRSI block to match the BRSC, the tester can provide the message procedure and message data specified in the IP system standard as desired by the investigator, and the success or failure of the test result can be determined. Output to the screen, so you can check and analyze the test results at any time during or after the test. In addition, the basic call management instance, which can be generated only by receiving the SSP's intelligent network message, can be automatically generated for each test item, thus providing the same test environment as when interworking with other intelligent network elements.
