In order to achieve the above object, the present invention provides a first step of generating a multi-process by setting the number of multi-processes after initializing statistical information and multi-call test data in a personal communication switch test method using a multi-call generator. After receiving the call test type and test control information to be performed in each process from the subscriber information database, the message sequence is selected to establish a communication path between each process and the exchange. When a response message is received from the exchange after transmitting to the exchange using a message queue, a third step of decoding the response message and checking the message processing capability of the exchange is performed. After the renewal, the exchange will be A fourth step of setting a communication path and releasing the communication path after a predetermined time; a fifth step of releasing a communication path established between each process and the exchange after completing a test procedure by sending a call release message to the exchange; And a sixth step of repeating from the third step a specified number of times after performing the test result output and the statistical database update.

Hereinafter, with reference to the accompanying drawings will be described an embodiment according to the present invention;

1A and 1B are configuration diagrams of a multiple call generator to which the present invention is applied. The common line signal (SS No. 7) protocol 1 handles the protocol matching function of the multiple call generator and the personal communication exchange period. The voice board 2 is hardware for testing the voice call path of the multiple call generator and the personal communication exchange period, and '' Motorola's System Bus (WEBus) matching board (MVME162) (3) is the VME of the multiple call generator. The rack-mounted, real-time operating system that manages the message processor layer 2 of the common line signaling (SS No. 7) protocol is running, and Greensprings' multi-protocol protocol-specific hardware board (IPcomm-302) (4) is the message transmitter layer 2 In charge of. The E1 multiplexer 5 performs the E1 matching function between the switch and the multiple call generator, the central processing unit 6 controls each component of the multiple call generator, and the input / output processor 7 the multiple call generator. Responsible for the I / O processing of

The functional blocks for testing the personal communication switch 8 are as follows.

The base station controller emulator 9 is responsible for the matching function between the call generator 10 and the common line signal (SS No. 7) protocol 1, and the call generator 10 provides multiple mobility management and call processing functions. It is responsible for coding and decoding a layer 3 message for testing, and the call generation control / statistical information output 11 is responsible for setting the selection function according to the request of the investigator and controlling the overall multi-call test. The mobile terminal information 12 is responsible for generating, retrieving, and deleting information of the mobile terminal for the multiple call test.

2A and 2B are flowcharts of a personal communication switch test method according to the present invention. To perform the multi-call test, the user selects call processing, location registration and deletion, handover function such as local call, other call, and fixed call that can be tested for each mobile terminal, and clicks the start test button. Based on this, multiple processes are created. In addition, it can be tested by specifying the frequency of occurrence by periodic repetition test and test type. Simultaneously created multiple processes monitor the system resources and make the most of the available resources to generate messages and send them to the exchange through the common line signaling (SS No. 7) protocol for testing. It also collects and analyzes statistical and error information in real time during the test process and outputs process-specific and total information on a user-matched graphic screen.

In order to test a personal communication switch, it is possible to test using a plurality of mobile terminals. In order to simulate a large number of mobile terminals in this multi-call generating apparatus, each mobile terminal call number, called number, terminal equipment number (ESN), And location information. Therefore, the information of the mobile terminal and the data for starting the test are initialized (21).

The number of multiple processes to be executed in parallel is set according to the system memory, the central processing unit computing power, and the resources of the common line (SS No. 7) signal link (22), and a test multiple process is generated (23).
