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 VME Bus Matching Board (MVME162) (3) is a VME rack of the multiple call generator. And a real-time operating system that manages the message processor layer 2 of the common line signal (SS No. 7) protocol, and Greensprings's multi-communication protocol dedicated hardware board (IPcomm-302) (4) is a 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 processes the multiple call input and output. In charge of.

The functional blocks for testing the personal telecommunication 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 functions with multiple mobility management and call processor functions. It is responsible for coding and decoding the layer 3 message to test the call generation control / statistics information output (11) is responsible for the setting of the selection function according to the request of the tester and the control of the entire 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 a flow chart of a personal communication switch test method according to the invention.

In order to perform the multiple call test, the user selects the call processing, location registration and deletion, handover function such as local call, other station, and fixed call, which can be tested by mobile terminal, and clicks the start test button. Based on this, multiple processes are created. In addition, the test may be performed by designating a periodic repetition test and an occurrence frequency for each 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. In addition, the statistical information and error information is collected and analyzed in real time during the test process, and the process-specific and total information is output on the 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 performed 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).

Mobile terminal subscriber information database (25) which manages call processing related information such as call number, called number, terminal equipment number, and location information of mobile terminal and call delay time, test type, history management, test count, debugging information, etc. ) Is provided with the call test type to be performed in each process and the test control information required in the test process (24, 26).

The call processing procedure according to the IS-634 standard is loaded from the defined file manager message sequence file 28 into the test control block according to the call test type (27).

In order to establish a communication path between the corresponding process and the base station controller emulator for sending and receiving messages to and from the exchange, the message queue provided by the UNIX operating system is initialized. 7) bind to the signal connection control unit user layer of the protocol stack (29).

A layer 3 message defined in the message sequence is generated, wrapped in a complete layer 3 message, and delivered through a message sending (spusendToPCX) function (30).

Monitor the emulator's message queue in No Waiting mode to receive messages from the exchange. Examine the time from the transmission to the reception to check whether the threshold time is exceeded to check the message processing capability of the exchange, and configure the information elements through the message decoding function function (31) to check for conformance and format errors. If it is an error (32), it updates the statistical data and ends (33).

If the test is required as a call like an incoming / outgoing call in the procedure of receiving message analysis instead of a message error (34), voice processing implemented in a personal computer (PC) using a socket, which is a network function of UNIX. A message including a corresponding time slot is transmitted to the board to configure a call path with the exchange (35), and a timer is driven to perform a call release procedure after a predetermined time (36, 37).

If the test is not a call or the call release procedure is completed, a call release message is sent to the exchange to terminate the test procedure (38), and the common line signal (SS No. 7) link formed between the emulator and the multiple call generator is connected. (39) The test results are graphically outputted with the test call type, common line (SS No. 7) message statistics, error information by type, and the success or failure of the test by process, and the statistical database is updated (40). ).

The message is repeatedly performed from the message generation and transmission process 30 according to the number of repeated tests, and ends when the repeated test is completed (41).

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains, and the above-described embodiments and accompanying It is not limited to the drawing.

The present invention as described above, by requesting a large number of calls to the personal communication exchange to increase the reliability of the service by testing the function and performance of the exchange, anytime, anywhere, anyone can use a better exchange in the development of personal communication service By enabling the development, it is effective to provide a convenient service to the subscriber at a low fee.
