Abstract

PURPOSE:To use processing to be executed by processing programs in common and to reduce the requires memory capacity of a communication control program by providing the communication control system with a matrix table and a processing means for switching the matrix table to a necessary value. CONSTITUTION:At the time of receiving a trigger 22 to be a request event by the status 12 of procedure attained by the matrix table ID=XX, a processing program (b) executes processing (b). When control is changed to the status C and the table ID=YY belonging to the matrix table ID=YY, control is transferred to the table ID=YY extracted and arranged by the processing common to respective communication control procedures. Although the values of the table ID=XX is receded to a communication control management table, the status value is also receded if necessary. Thereby, switching to the matrix for executing common processing can be attained, processing based upon the common matrix table can be attained, the switching system to the matrix is made common, and the required memory capacity of the communication control program can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention provides an O8 for communication control in an online system.
Regarding the program startup method.

(Prior Art) As a conventional method for starting a communication control program, a communication control method was realized as shown in FIG. 4 by creating a matrix table corresponding to a communication control procedure. In the communication control state, the processing program to be activated is determined by a request event (trigger) from the higher-level software or the line side.

In the communication control procedure, each communication phase has a management state (phase) according to the procedure, and when a request event from the upper software or the line side is received according to each management state, the processing program to be started is selected. are doing.

When the processing program is started, it executes the processing necessary for the communication control procedure, and also changes the state of the corresponding line to the management status (status) corresponding to the corresponding communication phase.
It has the next request event to be performed. The activation of the processing program by this request event is made to correspond to the communication phase by the transition of the management state (status), and the communication control program is realized by the selected matrix table.

(Problems to be Solved by the Invention) In the conventional communication control program startup method, a matrix table having a management state corresponding to a communication phase is required for each communication control procedure. Therefore, even if a similar communication control procedure is additionally supported, a similar matrix table must be created separately, resulting in an increase in the amount of memory required.

Furthermore, since different control information is provided for each procedure in the processing program, there is a drawback that adding a procedure requires adding another processing program, resulting in an increase in the required memory capacity.

An object of the present invention is to have a communication control management table for each line, set control information corresponding to communication control procedures in a matrix table, standardize the processing executed by the processing program, and manage the management status according to the communication phase. It is an object of the present invention to provide a communication control system using matrix switching, which eliminates the above-mentioned drawbacks by switching the matrix table to a necessary value, and is configured so that the required memory capacity often increases.

(Means for Solving the Butterfly Problem) A communication control system using matrix switching according to the present invention is configured to include a matrix table and processing means.

The matrix table is used to set control information corresponding to communication control procedures and to share processing executed by processing programs.

The processing means is for switching the matrix table to a required value in a management state according to the communication phase.

(Implementation 8ill) Next, the present invention will be explained in detail with reference to the drawings.

The eleventh is an explanatory diagram showing state transition in an embodiment of the communication control method using matrix switching according to the present invention.

In FIG. 1, 12 to 15 are management states (status), 22 and 26 are request events (trigger), and 32, 33, and 35 are processing programs, respectively.

FIG. 2 is an explanatory diagram showing one row of a matrix table related to FIG. 1'.

FIG. 3 is a communication control management table related to FIG. 2.

Assume that a processing program for implementing a certain communication control procedure is started using the matrix table shown in FIG.

When a request event trigger 22 is received according to the management state (status) 12 of the procedure realized by matrix table ID=XXK, processing program b executes the processing shown in FIG. Status C, table ID = XY belonging to
Matrix table ID = extracted and organized by common processing for each communication control procedure by changing control to
Move to XY.

At this time, from the matrix table that is the starting source = XX
The O value is saved in the communication control management table shown in FIG. 3, and the status is also saved if necessary. child,
) LK, it is possible to switch to a matrix that executes common processing and execute processing using a common matrix table.

The process of returning from the common process to the starting source is executed as follows. That is, when the trigger 25, which is a request event, is received due to the status D of the common matrix table ID=XY, the above processing is realized by the processing program C that is started.

After executing process C, the processing program C obtains the ID@XX of the matrix table saved in the communication control management table in order to move to the starting matrix table ID=XX, and transfers the migration destination status value E to the starting source. Change this with. In some cases, instead of using the saved status value as the status in the communication control management table, there is a case where the status returns to the original activated state of the matrix.

In this matrix table switching process F[, differences in control conditions of matrix table control procedures are absorbed by the following process.

When migrating to the common processing matrix, the necessary controls (44 items are executed as processing in the processing program. When accessing the activation source matrix from the common processing matrix, control information of the accommodation procedure of the activation source matrix is stored in advance. By setting this in the communication control management table and executing it as process C in the processing program that returns to the activation source matrix as needed, differences in activation sources can be absorbed and the processing programs can be made common.

(Effects of the Invention) As explained below, the present invention focuses on the communication phase of a communication control program that implements a communication control procedure, and commonizes control difference information in the processing program in a communication control management table in units of nine. This has the effect of making it possible to share the logic of processing programs. In addition, by standardizing the processing program, the matrix IJ table for changing the processing program can be separated from the common part, and the method for switching to the matrix can be standardized, reducing the memory requirements for the communication control program. This has the effect of reducing the amount of time required for debugging and maintenance.

In addition, if differences in procedures are recognized as setting information in the communication control management table by standardizing the processing program, the communication control management table can be easily incorporated into the processing program as control information corresponding to the procedure with additional support for communication control procedures. It has the effect of being able to
