In FIG. 2a, the message sequence file is a data file that defines the sequence of messages to be transmitted and received and the characteristics of each message, which are determined during the interworking function test of the personal communication exchange.

The message sequence file includes one file for each defined message procedure, and is classified into two categories, one containing information on the message procedure and the message characteristics defined in the protocol specification, and cannot be changed by the tester and is always present in the simulator. Template message sequence file. The second is a file that defines the message procedure and message characteristics defined by the tester so that the tester can test by changing the message procedure and message characteristics. The file is changed by the tester based on the template message sequence file and stored in a separate file. Message order file.

As shown in the figure, the order of the data stored in one file indicates the order of messages to be transmitted and received, and the components of these data are message identifiers defined in the protocol specification. A message identifier field 201 having a message, a transmission mode field 202 indicating whether a message is transmitted or received in the present invention, a timeout field 203 indicating a maximum time value waiting for a response of a transmitted message, a message Message condition field 204, indicating that the message is mandatory, conditional, optional, 'On / NoHold' to indicate whether to output or hold the message data after the message has been sent or received, Trace mode field 205 shown as 'On / Hold' or 'Off', indicating whether an abnormal message should be sent when sending the message. The normal status display field 206 is configured.

Message sequence file field (213), transmitted according to the message sequence file Which consists of a log (Logging) mode field 214 indicates whether or not to record the message data.

3 is a simulator process flow diagram according to the present invention, which is performed at a higher layer of TCAP 106.

As shown in the figure, when the present invention starts execution, a start program operates to set parameters of No. 7 common line signaling method and outputs a start screen to the terminal to perform system initialization (300), and to receive a message and tester. Waiting state 1 (301) is awaited operation.

When the standby state 1 301 receives a request to open a subscriber database (hereinafter referred to as DB) data file from the tester (302), the subscriber DB data file is read and the information of the parameter and the actual data value are displayed on the screen. (303).

The subscriber DB data is data holding all service information for the mobile subscriber stored in the subscriber information processing apparatus, and is used as basic data of service (call) processing for the mobile subscriber performed by the electronic switching center. Therefore, the simulator of the subscriber information processing device should retain the data and be able to manipulate it.

Therefore, the user receives the changed or added data from the examiner with respect to the parameters of the subscriber DB data output to the terminal, changes or adds the information of the subscriber DB data file (304), and switches to the standby state 1 (301).

When the message sequence file opening operation is requested from the tester in the standby state 1 (301) (305), the selected file is read from the tester and the message transmission / reception procedure is graphically displayed according to the data order of the file, and the parameter information and the actual data are displayed. The value is output to another part of the screen (306), when the tester changes the parameter value through the screen, the data is input and the corresponding parameter data value is changed (307), and the new file is checked (308).

As a result of confirming whether the new file is the new file, the new message sequence file is received from the tester and stored in the same manner as the abnormal message procedure (309), and the tester-defined message sequence file parameter of the lookup table (LookUp Table) is stored. Add new message order file information to the other parameters are set to the default value (310), and then switched to the standby state 1 (301).

On the other hand, as a result of checking whether the new file is the new file, if it is not stored in the new file, only changed data is stored in the basic file (311) and the standby state 1 (301) is switched.

When the start message is received from the electronic switch in the waiting state 1 (301) (312), the lookup table (LookUp Table) is searched (313) to obtain information of the message procedure to be performed next (313). Obtain the sequence file information, read the corresponding message sequence file (314), output the message procedure graphically to the terminal according to the contents of the read data, and output the parameter values to other parts of the terminal screen (315), then look up the sequence file The logging mode is checked among information of the lookup table (316).

As a result of checking the logging mode, if logging is 'on', the data of the received message is stored (317). If the logging is not 'on', the information of the received message is displayed in the information of the message sequence file. After checking the tracking mode (318), if the tracking mode is 'on', the raw data of the received message is output to the screen (319), and then the tracking mode is 'On / Hold' (On / Hold). 320).

As a result of the check, if the tracking mode is 'On / Hold', the wait state 2 321 is waited for the continuous or stop operation from the tester. When the tester command is checked in the standby state 2 (321) (322), if the operation command from the tester is the test stop, the standby state 1 (301), and if the tester operation command is continued, and the tracking mode In step 319 and 320, if the tracking mode is not 'ON' and if it is not 'ON / HOLD', the message to be transmitted (responded) is determined based on the data of the message order file (323).

In order to generate a message, the subscriber data file is read (324), a message is produced and transmitted according to the protocol standard (325), and the next message is determined based on the data of the message sequence file (326). If is not present, the test is determined and the result is output to the terminal (327), and the standby state 1 (301) is reached. If there is a transmission message, the process proceeds to the step of determining the message to be transmitted (323). The following procedure is performed, and if there is a received message, a waiting state 3 (328) is waited for a message from the electronic switch.

When the message is received from the electronic switch in the standby state 3 (328) (329), the process proceeds to step 316 to confirm the logging mode.

In the standby state 1 (301), when a test procedure for a message procedure that is first started in the personal communication subscriber information processing apparatus is received, when a test execution operation is requested from a tester (330), it is checked whether a message sequence file is opened (331). ), When the message sequence file is opened and information is output to the terminal, receiving a parameter that needs to be selected from the examiner (332), and searching the sequence file lookup table to obtain information of the message procedure to be performed (313). If the message sequence file is not open, the tester malfunctions (333) and enters the standby state 1 (301).

When the abnormal message test operation is requested from the tester in the waiting state 1 (301) (340), the message ordering file is opened (335), and if the message ordering file is not open, the tester malfunctions (336). When the message sequence data file is open, the parameter input information is output to the terminal in order to receive data for generating an abnormal message from the tester (337), and the parameter from the tester. Is input (338), an abnormal message is displayed on the selected message among the data of the message sequence file, the input parameter is stored (339), and the standby state 1 (301) is entered.

When the end operation is requested from the tester in the standby state 1 (301) (340), the simulator process is stopped (341) and ends.

According to the above, the present invention can be easily accommodated even if the higher protocol standard of the Transaction Capabilities Application Part is changed in the No.7 common line signaling method, so that the function test of the personal communication switchboard may be performed. Instead of providing personal communication subscriber information processing device, not only provide protocol procedure according to MAP protocol standard, but also send and receive messages according to protocol specification or tester-defined message procedure and message characteristics to test abnormal processing procedure. do.
