Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a switching system, and in particular, to maintenance and maintenance provided by a switching system that is input and sent from a plurality of terminal users.
The present invention relates to a command conflict management method for operation commands.

[Conventional technology]

Conventionally, this type of command conflict management system assigns, for each command, a command conflict management number used in command conflict management and data indicating whether or not a conflict operation with another command is possible in correspondence with the command conflict management number. Every command conflict management managed by command conflict management command execution management data by command number
The command conflict management method is used to perform command conflict control based on impossible data.

[Problems to be Solved by the Invention] In the command conflict management method for maintaining and operating the conventional switching system described above, for each command in the switching system, the number managed by the command conflict management and other commands are The competing operation possible / impossible data was given. As described above, since a large amount of memory is used for each command because competing operation possible / impossible data with other commands is required, the number of commands provided by the switching system must be limited due to the amount of memory. Since the command conflict management number area is also reserved in advance, a number area that is not assigned is also conceivable, and there is a disadvantage that memory is wasted.

Furthermore, since there is no number of commands being executed for each command conflict management number, when multiple commands use the same command conflict management number, both commands are being executed 1
If only the command is command-terminated, the command having the command conflict management number will give a conflict action enable instruction. Therefore, if multiple commands with the same command management number are being executed, and one of the commands has finished, and the command with the true management number is still being executed, the command entered next will be the command conflict described above. When the conflict operation impossible data is set for the command having the management number, the command conflict check is OK (OK). As a result, there is a drawback in that a command input afterwards will execute an execution process even though the command which originally has a true management number cannot conflict with the command.

Therefore, most of the present invention is to provide a command conflict management system that does not limit the maintenance / operation commands of the exchange system and can effectively use the memory.

[Means for solving problems]

The command conflict management system in the exchange system of the present invention comprises an exchange and a plurality of terminals, the terminal responds to an input request from the exchange and sends a maintenance / operation command provided by the exchange system, and the exchange receives the input command. In a switching system configured to execute a corresponding command processing program, the maintenance / operation commands provided by the switching system are divided into a plurality of command groups in advance, and a command family number for managing this is given to the divided command groups. , Manages the number of command executions within the same command family number corresponding to the command family number and the presence or absence of executing commands within the command family. Also, each command manages its own command family number and the command family number for other commands Each command processing by managing whether the command conflict After the program is started, the command is processed by the data indicating the command conflict number corresponding to the command family number managed by each command processing program and the data indicating the presence or absence of the executing command in the command family corresponding to the command family number managed by the exchange system. It has a control means for performing a conflict check.

EXAMPLES Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention.

The exchange 1 manages each user space 6,7,8,9 for controlling data such as commands and messages input and sent from the terminal users 2,3,4,5 connected thereto and command conflict management. It has a command conflict management space 15 for execution and a function space for fulfilling the function of the exchange system.

User space for each command entered and sent 6,7,8,9
Has programs 10, 11, 12 for controlling terminal transmission data (commands, data, etc.), and in particular, the command processing program 12 (corresponding to FIG. 3 described below) is its own command family number data 13 and command. It has conflict check pattern data (unsigned type 32 bits) 14.

The command conflict management space 15 is used as a command conflict check processing program 18 at command activation (corresponding to FIG. 4 described below), a command termination program 19 at command termination (corresponding to FIG. 5 described below) and management data. Command family number-adaptive flag data (unsigned type 32
Bit) 16 and execution counter data 17 for each command family number.

Command conflict check pattern data 14 of each command processing program and command flag No. corresponding to command family number 16 managed in command conflict management space
Controls each bit of data by associating it with a command family number.

FIG. 2 shows the structure of maintenance / operation commands provided by the exchange system.

All maintenance / operation commands 20 provided by the exchange system are divided into a plurality of command groups 1A, 2A to 32A, and command family numbers 1B and 2B to 32B are given to them (32 commands in this embodiment). It is divided into groups).

The present embodiment will be described below with reference to the flow charts shown in FIGS. Here, FIG. 3 shows the whole process, FIG. 4 shows the command conflict check program in FIG. 3,
FIG. 5 shows the command termination program in FIG.

The command sent from the user terminal is activated after input control. After starting, as shown in Fig. 3, the command processing program first gives its own command family number after checking the parameters (steps), and then the command conflict check pattern (32-bit data corresponds to this family number bit). Is set to 0 when conflict is possible and 1 is set when conflict is not possible), and the command conflict check program is called (step,).

In the command conflict check program (see Fig. 4),
Check the input command family number (step), and if there is a problem (NG), return a command family number error (step; N). If OK (step;
Y), the command flag corresponding to the command family number that is the input command conflict check pattern and command conflict management data (32 bit data: 1 if there is an executing command for this command family number corresponding bit, 1 if no executing command) If 0 is set, 0 is set), and the command conflict check is performed by taking a logical product with (0) (step).

When the result is = 0, it is determined that the command conflict check is OK, 1 is set as the command family number bit in the command flag corresponding to the command family number (step), and the execution counter data for each command family number is incremented by 1 ( Step). Also, the result is
When = 1, an error is returned as a command conflict check NG, and the command processing program which has obtained this terminates the processing.

The command processing program (step; Y) that has returned the command conflict OK sets the own command family number when the command ends and calls the command end program (step ~).

As shown in FIG. 5, the command end routine checks the input command farimi number (step),
If the check is OK, the execution counter corresponding to this command family number is decremented by 1 (step). Here, if the execution counter corresponding to this command family number becomes 0,
Assuming that there is no command being executed within the command family number, 0 is set to this command family number corresponding bit of the command family number corresponding execution flag, and the process returns to the command processing program (step,). The command processing program can then terminate.

〔The invention's effect〕

As described above, the present invention divides the maintenance / operation commands provided by the exchange system into a plurality of command groups, assigns the same management number to the commands belonging to the same command group, and manages the command conflict for each management number. By doing
The maintenance / operation commands of the exchange system can be provided without restriction, and the memory can be effectively used.

Further, by managing the command execution counter data for each command family number by the command conflict management, it is possible for a plurality of commands to have the same command conflict management number (called the command family number in the embodiment). There is an effect.
