The present invention relates to a restriction processing apparatus and method for an input command in an electronic switchboard, and in particular, selectively according to the load of a processor that processes an input command when an operator command is input, such as output / change / deletion of various information. The present invention relates to a restriction processing apparatus and a method suitable for performing restriction processing.

In general, electronic switchboards have hundreds of operator instructions, and the corresponding processing is performed in the software block related to the instructions according to the inputted instructions to output the result to the operator terminal, the input / output processing unit.

1 is a hardware configuration diagram illustrating a process of processing an input command in a conventional all-electronic exchange.

Referring to FIG. 1, when an operator inputs a predetermined command through the input / output processing unit 100, the operator matching unit 111 in the central control unit 110 receives the received command, and the operator matching unit 111 inputs the received command. After checking whether the error is checked through the instruction interpreting means 112, a processor capable of processing the instruction in the normal case requires processing of the instruction. At this time, since the processor information necessary for the instruction processing is predefined in the input instruction, the input instruction interpreter 112 can grasp the processor to be processed when interpreting, and the instruction processing request is made to the corresponding processor based on the determination result.

Therefore, when the input command corresponds to the subscriber and the trunk line matching unit 120 (1) -102 (n), the command processing request signal is transmitted to the subscriber and the trunk line matching unit 120 (1) -102 (n). If it is related to the network control unit 130, the command network request signal is transmitted to the network control unit 130. Accordingly, the instruction processing means 121 and 131 in each processor perform the corresponding processing, and when the processing is completed, the processing result is sent back to the operator matching unit 111. The operator matching unit 111 transmits the received processing result to the input / output processing unit 100 through the result output unit 113.

As described above, conventionally, when the load of the processor is severe, the instruction processing may not be normally performed by allowing the operator to process the input command regardless of the load of the processor having the instruction execution means.

Accordingly, an object of the present invention is to provide an input instruction limit processing apparatus and method capable of adaptively performing a process for an inputted operator instruction in accordance with a load state of an instruction processing processor in an all-electronic exchange.

In accordance with an aspect of the present invention, there is provided an apparatus for performing restriction processing on an input instruction in an electronic switchboard that processes an instruction according to an operator's request. And an input / output processing unit for outputting a processing result for the input command. An operator matching unit for interpreting the input / output processing unit and outputting a load test for a processor to process an instruction input from the input / output processing unit and a processing result for the input instruction; And a database storing process related load information, wherein the operator matching unit comprises: input instruction analyzing means for analyzing an instruction applied from the input / output processing unit and analyzing information about a processor to process the instruction; And a load class for the processor which is to be controlled by the input command interpreting means, using the information related to whether or not the instruction has priority and load related information about the processor that is to process the instruction read from the database. It provides a limiting processing device for the input command in the electronic switch, characterized in that it comprises a processor load check means for checking and providing to the input command interpreting means.

Method according to the invention, if the command is input by the operator, the step of analyzing the input command; Checking whether the instruction is processed in a specific processor or through multiple processors at a system level by analysis; A first load state checking step of checking a load state of the processor when the instruction is processed by the specific processor; A second load state checking step of checking a load state of the entire system when the instruction is processed through several processors; Performing the processing of the input command when the load rating is not equal to or greater than a reference value as a result of the check in the first load state checking step and the second load state checking step; The electronic load changer comprising the step of outputting a non-implementation message and not processing a command when the load class is equal to or larger than a reference value as a result of checking in the first load state check step and the second load state check step. Provides a method for handling restrictions on input commands.

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

2 is a block diagram of an input command restriction processing apparatus according to the present invention in an electronic switch, an input / output processing unit 100 for outputting a command approved by an operator and a processing result for an input command, such as an operator terminal, Subscriber and trunk line matching unit 120 (1) -120 (n) having a central control unit 200 in the electronic switchboard, an instruction execution unit 121 for processing a corresponding command, and inputted commands The network controller 130 includes an instruction execution unit 131 for performing a corresponding process, and a database 210 storing load-related information for each processor.

In particular, the operator lower part 201 in the central control unit 200 may include the input command interpreting means 202 and the input command interpreting means 202 for analyzing (or interpreting) the command applied from the input / output processing unit 100. Processor load checking means 203 for performing a load check on a processor to process an instruction authorized by a request; and a result output means for outputting to a input / output processing unit 100 when a processing result for an instruction input from each processor is received. 204 is provided.

3 is a flowchart illustrating a method for processing an input command restriction according to the present invention.

Next, the operation of the present embodiment will be described in detail with reference to FIGS. 2 and 3.

When the operator inputs an operator command related to the exchange system through the input / output processing unit 100 in step 301, the operator matching unit 201 in the central control unit 200 receives the input command, and the process proceeds to step 302. It is applied to the interpreting means 202 to analyze the input command. At this time, when analyzing the input instruction as described above, information about the processor to process the instruction is obtained. At this time, the information about the processor is classified into a case where only a specific process is processed and a case where a processor is processed through multiple processors at the system level.

Therefore, it is checked whether the command currently input in step 303 is a command for a specific device based on the information on the processor obtained by the analysis performed in step 302. As a result of the check, in the case of an instruction that needs to be processed through several processors at the system level, the process proceeds from step 303 to step 304 to set the value ALL to the device flag variable. However, if the command corresponds only to a specific device, the flow proceeds from step 303 to step 305 to set the device name in the device flag variable.

In step 306, the state of the set device flag is checked. If the device flag is ALL, the input command interpreting means 202 performs processor load checking means to perform a system-wide load test in step 307. 203 is controlled. However, if the device flag is not ALL, the input command interpreting means 202 controls the processor load checking means 203 to proceed from step 306 to step 308 to perform only load checking on the corresponding device.

The processor load checking means 203 then checks the priority of the input instruction (step 309). The priority of a command is included in the command information in the command definition step. At this time, the priority of all commands is not defined, and the command is classified into a command having priority and a command without priority according to its importance. That is, the commands having priority are selected for commands that are important for the operation management and maintenance of the system. The reason for checking the priority when checking the load on the processor is that the load class for the instruction having priority and the instruction having no priority is different. In other words, the load class for each processor is divided into processor down state, critical load state, major load state, minor load state, and normal state. In the normal state, the minor load state, and the major load state, the instruction without priority is processed only in the normal state and the minor load state among the above-described load classes.

Therefore, in step 309, the processor load checking means 203 performs priority check on the input instruction and reads the load state of each processor stored in the processor load database 210 according to the check result of the priority. And the priority and the load state read from the processor load database 210 to check whether the load state of the processor to process the input instruction is greater than or equal to the reference value.

If the result of the check is not equal to or greater than the reference value, processing is possible. Therefore, the process proceeds from step 310 to step 311 so that the processor load checking means 203 transmits a message to the execution block of the corresponding input command. send. Accordingly, the input command interpreting means 202 terminates the restriction processing operation on the input command and makes a request to perform the execution block for the input command. In this case, the above-described execution block is an instruction execution unit 121 or 131 in each processor. The next process processed by the command performing means 121 or 131 is performed in the same manner as in the prior art.

However, when the check result of step 310 indicates that the load of the processor to process the input instruction is greater than or equal to the reference value, the processing is not possible, the processor load checking means 203 proceeds from step 310 to step 312 to load the processing apparatus. Due to the improper execution of the command is difficult message is transmitted to the input command interpreting means 202. Accordingly, the input command interpreting means 202 transmits a non-implementation message to the input / output processing unit 100 and then ends the restriction process for the input command.

As described above, the present invention is to check the load state of the processor before performing the instruction processing function of the operator in the electronic switchboard to perform the limit processing for the input command, the abnormal state of the input command due to the load of the processor Can be effectively prevented.
