In the personal communication service (PCS), the subscriber information processing device is connected to a personal communication exchange and performs information exchange through a protocol of an application layer called a Personal Communication Application Part (PAP) protocol. Therefore, in the subscriber information processing device simulator, the PAP protocol must be performed so that information can be transmitted by being connected to the electronic exchange before personal communication.

In order to load the PAP in the subscriber information processing device simulator most efficiently, the PAP structure should be the same as the PAP structure proposed in the protocol specification. The PAP structure is largely classified into a PAP provider section and a PAP user section. The PAP user section actually requests and executes the personal communication application service. To this end, the PAP user section uses various primitives provided by the PAP provider section according to a predetermined procedure.

Therefore, a PAP user unit is required to test the PAP function of the personal communication exchange using various primitives provided by the PAP provider in the subscriber information processing device simulator.

Accordingly, in order to provide various test methods for testing the PAP function of the electronic exchange before personal communication in the subscriber information processing device simulator, the present invention provides a PAP provider section And to provide a protocol processing method of a personal communication application unit for processing common / application service primitives.

According to an aspect of the present invention for achieving the above object, there is provided a personal communication application unit (PAP) which performs a personal communication application unit (PAP) protocol using a service provided by a dialogue processing function application unit, and provides a common primitive and an application service primitive, A test control manager for performing functions corresponding to the purpose of the simulator using various primitives provided by the personal communication application part (PAP) provider while managing the control and data for the provider part and the overall test, and a subscriber data, message sequence data, (PAP) protocol processing method applied to a subscriber information processing device simulator configured to include a data file for storing data, After initializing the data such as reading data about the stored information, Upon receiving the message sender from the tester, it determines the message procedure of the service function to be performed, generates and stores the application context name, requests the PAP provider section to start the PAP, Upon receipt of the signal, it examines the error status of the received message, generates an acknowledgment primitive and transmits it to the Personal Communication Application (PAP) provider, stores the application context name, determines the message procedure, A first step of switching to a service waiting state; Upon receipt of the PAP primitive instruction signal from the PAP provider unit in the application service waiting state, the error status of the received message is checked. If the subscriber data is required to be changed according to the received message after changing the subscriber data , If the message to be transmitted does not exist in the second step of determining whether there is a next message to be transmitted according to the message procedure after activating the requested test function by the tester, the message application context name is assigned to the stored application context name , Transmits a PAP end request signal to the PAP provider unit, completes the message procedure, generates a conversation identifier if it is not a new application context request but a response message of the received message if a message to be transmitted exists, and stores the conversation identifier , Transmits a PAP primitive request signal to the PAP provider unit, A step of transmitting a PAP application service start request signal, which is a request signal for requesting transmission of a private communication exchange symbol, to the PAP provider unit and receiving a PAP primitive confirmation signal from the PAP provider unit to check whether the subscriber data should be changed according to the received message And a third step of performing the following steps.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram of a subscriber information processing device simulator to which the present invention is applied. In FIG. 1, reference numeral 10 denotes a NO.7 common channel signal network matching board driver, 12 denotes a message transmission unit level- MTP-3: Message Transfer Part level 3 / SCCP: Signaling Connection Control Part), 13 is Transaction Capabilities Application Part (TCAP), 14 is Personal Communication Application (PAP) 'Denotes a test control management unit,' 16 'denotes an operator matching unit, and' 17 'denotes a data file.

The subscriber information processing device simulator is capable of attaching peripherals such as terminal, printer, and cartridge driver, and is equipped with a system bus (VME Bus) which is a standardized bus and a UNIX system which is an operating system of a general computer system It is configured on the computer.

The subscriber information processing device simulator is connected to the E1 trunk of the personal communication exchange, and mounted on the system bus of the general-purpose computer to support the NO.7 common line signaling system. The IP-302 and IP-E1 cards A NO.7 common signal network matching board (MVME-162) (10), which is mounted in the board and performs level 1 and level 2 signaling, adds a special purpose new board to the general-purpose computer's system bus, NO.7 common signal network interface board driver (11) implemented in the UNIX kernel (Kernal) layer for transmitting and receiving information between boards, and level 3 and level 4 of the lower protocol of NO.7 common signaling method (TCAP) 13 for performing a dialogue processing function, which is an upper protocol of the MTP-3 / SCCP 12, the No. 7 common signaling method, In the Interaction Processing Function Application (TCAP) (13) A personal communication application unit (PAP) provider unit 14 for providing a common primitive and an application service primitive to a PAP user as a test control management unit 15 while performing a PAP protocol using a public service, A test control manager 15 serving as a PAP user that performs a function suited to the purpose of the simulator using various primitives provided by the PAP provider unit 14 and a graphical user interface A Man Machine Interface (MMI) 16 for receiving data from a tester or outputting test information through a graphic screen of the terminal, subscriber data required for executing a subscriber information processing device simulator, message sequence data, message logging And a data file 17 for storing logging data.

Here, certain types of information transmitted and received between the PAP provider unit 14 and the PAP user as the test control management unit 15 are referred to as primitives, which are largely divided into common primitives and application service primitives.

The common primitive is a primitive commonly used when the PAP user 15 requests an application service to the PAP provider unit 14. The primitive types for performing a normal application service primitive are PAP start (open), PAP end (open) close), the PAP application service delimiter primitive is used.

The application service primitive is a primitive that provides various application services required to perform the personal communication service performed by the application unit of the subscriber information processing device simulator.

A primitive transmitted from the subscriber information processing apparatus to the personal communication exchange, that is, a primitive transmitted from the PAP user 15 to the PAP provider unit 14 includes a Request / Response primitive for each common / Primitives that the PAP provider unit 14 transmits to the PAP user 15 include indications and confirms for each common / application service primitive, Lt; / RTI >

Here, the request is a primitive for a message to be transmitted when an operation corresponding to an application service is first generated in a subscriber information processing device simulator, and a response is a primitive for a message to be transmitted to a subscriber information processing device simulator Lt; RTI ID = 0.0 > received < / RTI >

Indication is a primitive for a message received from a subscriber information processing device simulator due to an application service generated at a personal communication exchange. Confirm is a primitive for an application service request generated in the subscriber information processing device simulator This is the primitive for the response message of the communication exchange.

2a through 2c show a flow chart of the personal communication application protocol processing according to the present invention.

First, when the present invention is performed, system data such as parameter setting of the No. 7 common line signaling method or data reading of information stored in the current file is initialized (301), and then through a graphical user interface And switches to a tester command waiting state for receiving a test execution command from the tester (302).

Upon receipt of a message reception command from the tester in the tester command standby state 302 (303), the system prepares to transmit and receive the message, and then switches to a message waiting state (304).

Upon receipt of the execution end command from the tester in the tester command standby state 302, the functions to be performed at the end of the program are performed according to the activated test function and terminated.

Upon receipt of a message sending instruction from the tester in the tester command waiting state 302 (306), a message procedure indicating the processing procedure of the service function is selected from the tester, the message procedure is determined with the selected contents, If an application context name is used, the message procedure is determined with the contents already selected (307).

Then, an application context name according to the message procedure is generated and stored 308, and a PAP start request signal, which is a common primitive, is transmitted to the PAP provider unit 14 to start a message procedure with the personal communication exchange 309 ), And switches to the message waiting state (304).

Upon receipt of the OPEN signal from the PAP provider unit 14 in the message waiting state 304, the PAP initiator OPEN signal is activated by the PAP start (OPEN) request signal, which is the common primitive transmitted before the PAP provider unit 14 (Step 325) of checking the necessity of changing the subscriber data, which is the step of processing the test function and transmitting the application service primitive thereafter.

Upon receiving a PAP start (OPEN) instruction signal as a common primitive from the PAP provider unit 14 (311) in the message waiting state 304, the personal communication exchange switches to the application context name included in the parameter of the primitive , It checks the error status of the parameters of the received primitive. If there is no error, it assigns the dialog acceptance value to the result value of the parameter of the response message. If an error occurs, (312). Here, a specific application context name is an information element representing a series of message procedures including one or more application services, and a message procedure for an application context name is defined in the protocol procedure.

The application context name parameter of the response message to the received common primitive is assigned the received common primitive value as it is, and the other parameter values are assigned to the parameter values stored in the data file, and the PAP start (OPEN) response signal (313). The application context name used at this time is stored in the data file (314) since the application context name must be used continuously until the end of the message procedure thereafter.

If there is no message procedure selected by the tester, the message procedure file corresponding to the application context name is stored, and the message procedure is determined (315), and the application service state is entered (316).

At this time, determining the message procedure according to the application context name indicates a normal message procedure, and the message procedure selected from the tester indicates an abnormal message procedure prescribed by the tester for testing.

When a PAP end instruction (CLOSE) indicating a common primitive is received from the PAP provider unit 14 (317) in the application service waiting state 316, the message procedure is completed (318) And switches to the command waiting state (302).

Upon receiving the PAP primitive indicating signal of the application service primitive from the PAP provider unit 14 in the application service waiting state 316, this is a message included in the common primitive 312, so that the application context name stored in the data file is used And verifies (320) whether it is an application service primitive defined in the determined message procedure.

If the check result is an error (320), an error process is performed on the received message reporting the error status (321), and the process is switched to the message waiting state (304). Otherwise, the response message is generated (Invoke Identification) included in the received message to store the message (322).

Here, the conversation identifier is a value that distinguishes a dialog formed during a private communication exchange to perform an application service. The conversation identifier uses the same value in the present invention with the private communication exchange, and the application service response message includes an application service request (Request) message.

If it is necessary to change the currently stored subscriber information according to the received primitive message (323), the subscriber data stored in the file is changed to the parameter value of the received primitive ( 324) and performs various activated test functions (325) such as a test function selected by the tester, that is, a message logging function, a message trace function, and the like.

After determining the message name and related characteristics to be transmitted from the selected message procedure (326), it is determined whether a message to be transmitted exists (327).

If the message to be transmitted does not exist (327), the message application context name is assigned to the application context name stored in the data file (328), and other parameters are assigned to the stored parameter values, And transmits it to the PAP provider unit 14 (329). Since all the message procedures have been performed, the information displayed on the screen is output (330) and the state is switched to the tester command waiting state (302).

If the message to be transmitted exists (327), it is determined whether the transmission message should use a new application context name (331). That is, it is determined whether a message procedure should be performed with a personal communication exchange other than the personal communication exchange that has previously transmitted the message, and if the new application context name is used, a message procedure is determined (step 307) If the application route name is not requested, it is checked whether the message to be transmitted is a response message of the received message (332).

In the case of the response message of the received message 332, the PAP primitive response signal, which is a response message of the received application service primitive, is allocated to the PAP provider unit 332 (Step 334).

A PAP application service start (DELIMITER) request signal, which is a common primitive used to instruct the PAP provider unit 14 to transmit the application service primitive, uses the stored application context name to the PAP provider unit 14, (335). After performing the activated test function (336), the application service is put into the standby state (316).

If the message to be transmitted does not form a response message but forms a new dialogue, that is, generates a new application service (332), a new talk identifier is generated and stored (337), and a PAP primitive request signal using this talk identifier To the PAP provider unit 14 (338), transmits a PAP application service start (DELIMITER) request signal using the stored application context name to the PAP provider unit 14 (339) (340).

Upon receiving the PAP primitive confirmation signal, which is a response message to the message transmitted in the response message waiting state 334 (341), the error state of the received PAP primitive confirmation signal is checked (342). If the parameter such as the conversation identifier value is an error Performs a processing procedure of the received response message, performs an error process for storing necessary data for the activated test function, and switches to a tester command standby state (302). If it is normal, (Step 323).

According to the present invention as described above, in order to provide various test methods for testing the PAP function of the personal e-mail exchanger in the subscriber information processing device simulator, the PAP provider It is possible to process a common / application service primitive provided by the subscriber information processing device simulator, thereby developing a new additional service in the personal communication service for the purpose of using the subscriber information processing device simulator.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventive concept as defined by the appended claims and their equivalents. It is not limited.
