Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a configuration of a protocol test device 20 for testing a protocol of an exchange 10 that communicates with a terminal device such as a telephone.

The protocol test apparatus 20 includes an operation unit 21,
It comprises a display 22, an SDL diagram creation unit 23, an SDL diagram selection unit 30, a test communication unit 31, an execution macro storage unit 32, and an interface 33.

The operation unit 21 is formed of, for example, a keyboard and a mouse, and the display 22 is formed of a CRT or a liquid crystal type image display.

The SDL diagram creation means 23 is provided with an SDL descriptor storage means 24, a message storage means 25, and an SDL editing means 26 so that an SDL diagram can be edited, created and registered on the screen of the display 22 by operating the operation unit 21. , Message editing means 27 and SDL diagram storage means 28.

In the SDL descriptor storage means 24, ITU-
SDL (Sp
Attribute and image information of an ecification and description language (descriptor) are stored in advance.

The message storage means 25 has an SD
Messages that can be written in the L descriptor are stored in advance for each type (attribute) of the SDL descriptor.

The SDL editing means 26 can be selected by, for example, a mouse operation on the left side of the screen of the display unit 22, as shown in FIG. 2, based on each image of the SDL descriptor stored in the SDL descriptor storage means 24. SDL descriptors a1 to a8
Is displayed, and a plurality of columns of cells for vertically arranging the selected SDL descriptors in the execution order are displayed in the center of the screen.

Note that each S displayed on the display 22 is
The DL descriptors a1 to a8 each have the meaning shown in FIG.

The SDL editing means 26 makes it possible to drag and drop, for example, the SDL descriptor selected by the mouse to an arbitrary cell. In addition, the SDL descriptor dropped in the cell can be deleted or overwritten by mouse operation or key operation.

The SDL editing means 26 stores the SD in the cell.
When the L descriptor is dropped, candidates for messages that can be written in the descriptor are displayed.

For example, when the type of the selected SDL descriptor is a descriptor indicating waiting for an internal event, "TEST
START. display a list of text such as "req"
Select this by operating the mouse or keyboard,
When the type of the selected SDL descriptor is a descriptor indicating waiting for an external event, “CALLPROC”,
A list of texts such as "ALERT" is displayed, and this is selected by operating a mouse or a keyboard.

If the type of the selected SDL descriptor is a descriptor indicating internal processing, "Time Out"
And a list of texts relating to internal operations of the apparatus such as a lamp display operation such as “LedSet” and the like, and the user is allowed to select the list by operating a mouse or a keyboard.

If the type of the selected SDL descriptor is a descriptor indicating internal message transmission, "Path
Test Exe. display a list of texts corresponding to specific messages relating to the operation of this device, such as "req"
This is selected by operating a mouse, a keyboard, or the like.

When the type of the selected SDL descriptor is a descriptor indicating external message transmission, "aler
A list of texts of messages normally output to the exchange, such as "t", "callproc", and "conn", is displayed.

When a specific operation of a mouse or a keyboard is performed during the display of this message, the message editing means 27
Is activated, and it becomes possible to edit and create an arbitrary external message to be output to the exchange.

The message editing unit 27 inputs or selects parameters such as a protocol identifier, a call number, a message type, and a message length by operating the operation unit 21 to create an external message corresponding to the selected parameter. .

Each SDL arranged in each cell as described above
A message is selected or created and written in the descriptor, and an SDL diagram corresponding to the protocol to be tested is completed on the screen of the display 22 as shown in FIG. 4, for example.

The SDL editing means 26 outputs the created S
The data of the DL diagram is stored as one SDL file in the SDL diagram storage means 28 including a non-volatile memory and a disk by operating the operation unit 21.

The SDL editing means 26 stores the SDL
The SDL file stored in the figure storage means 28 is read out and displayed on the display unit 22, and the contents are arbitrarily changed by operating the operation unit 21, and the changed SDL file is replaced with a new or previous file to replace the SDL diagram. The data is stored in the storage unit 28.

The SDL diagram selecting means 30 uses the operation unit 2 to select one of the SDL diagrams created by the SDL diagram creating means 23.
The user selects the SDL file arbitrarily by the operation 1 and sets the data of the SDL file corresponding to the selected SDL diagram in the test communication unit 31.

The test communication means 31 is an SDL diagram creation means 2
The SDL description of the SDL diagram selected by the SDL diagram selecting unit 30 from the execution macro storage unit 32 which previously stores the execution macros corresponding to the respective SDL descriptors including the SDL diagram message edited and created by the SDL diagram selecting unit 30 Read and execute the macros corresponding to the
The communication according to the figure is performed with the exchange 10 via the interface 33, and the communication protocol of the exchange 10 is tested.

As described above, the protocol test apparatus 20 according to the embodiment arranges the SDL descriptor displayed on the screen of the display 22 in an arbitrary cell, and selects and writes a message in the SDL descriptor. You can edit and create the SDL diagram of the protocol you want to test.
When any one of the L diagrams is selected, the selected SD among the execution macros stored in the execution macro storage means in advance is selected.
It is configured to execute an execution macro corresponding to each SDL descriptor in the L diagram to test a protocol according to the SDL diagram.

For this reason, it is possible to easily create or change the test content of the protocol, which has been difficult in the past, at the level of a general user, and it is possible to execute the created test content quickly without the need for compiling. .

The arrangement of the SDL descriptors on the display and the display format of the cells are arbitrary, and are not limited to the above embodiment.
