TECHNICAL FIELD OF THE INVENTION
The present invention relates to a resource audit processing system and a processing method for an exchange, and more particularly, to a resource for securing a resource upon occurrence of a call and releasing the resource upon termination of a call, performing a proper use check of an exchange resource, and forcibly releasing an illegally used resource. The present invention relates to an audit processing system and a processing method thereof.
[0002]
[Prior art]
Conventionally, as an auditing method of a switching system, an auditing process is started by checking at a predetermined time period (see Japanese Patent No. 2618126 and Japanese Patent Application Laid-Open No. 2-200049).
[0003]
[Problems to be solved by the invention]
In the above-described conventional switching system audit processing method, since the check is performed at a predetermined time period, even if the resource becomes busy, it is not possible to immediately release the illegally used resources, and there are many illegal uses of the resources. Thus, even if a call is lost, there is a problem that an audit for immediately releasing an illegally used resource cannot be performed.
[0004]
[Means for Solving the Problems]
The resource audit processing system of the present invention is a resource audit processing system that secures resources in accordance with the occurrence of a call and releases resources upon termination of a call, performs a proper use check of the resources of an exchange, and forcibly releases an illegally used resource. Resource management means for capturing and releasing resources necessary in response to a release request, and outputting resource usage information indicating the total number of resources and the number of resources being captured; and Upon receiving the resource usage status information from the management means, calculate the resource usage rate, which is the ratio of the number of resources being captured in the total number of resources, and start the audit execution of the resource with the calculated resource usage rate set in advance. Judge whether the standard usage rate that is the standard of A resource measurement unit that outputs an audit execution request when the reference usage rate has been reached, and when an audit execution request is received from the resource measurement unit, the resource being captured by the resource management unit uses the resource. Means for checking whether or not the resource is properly used and, if there is a resource that is not properly used, outputting an instruction to release the resource to the resource management means and causing the resource management means to release the resource;
[0005]
Further, in the above configuration, the resource measuring means may calculate a resource usage rate calculated based on the resource usage state information from the resource management means with a first reference usage rate serving as a reference for starting auditing of the resource. When the comparison does not reach the first reference usage rate, it is further determined whether or not the second reference usage rate serving as a reference for switching the mode of the usage rate measurement set in advance is reached. If the usage rate has not been reached, instead of receiving the resource usage information by autonomous transmission from the resource management means, receiving the resource usage information as a response to a transmission request for resource usage information transmitted at a predetermined cycle set in advance, If the second reference usage rate has been reached, the resource usage status information is sent to the autonomous transmission from the resource management means. When the resource management means receives the transmission request of the resource usage information from the resource measurement means, the resource management means displays the resource usage information indicating the total number of resources and the number of resources being captured at that time. To be sent to the user.
[0006]
Further, a reference usage rate (or a first reference usage rate) serving as a reference for starting auditing of the resources set in the resource measuring means is 100%, and the number of resources being captured matches the total number of resources. When the resource is busy, the auditing of the resource can be started.
[0007]
The resource audit processing method according to the present invention is a resource audit processing method for securing the resources in accordance with the occurrence of a call and releasing the resources upon termination of the call, performing a proper use check of the resources of the exchange, and forcibly releasing the illegally used resources. In addition to capturing and releasing resources required in response to a resource release request from the means that uses, resource usage information indicating the total number of resources and the number of resources being captured is created each time, and the total number of resources is calculated. Calculate the resource usage rate, which is the ratio of the number of resources being captured during, and determine whether the calculated resource usage rate has reached a reference usage rate that is a reference for starting audit execution of a preset resource, and If the usage rate has been reached, the resource being captured is justified by the means that uses the resource. If it is checked whether it is used, not being legitimate uses resources, with the step of releasing the resources.
[0008]
Further, in the above-mentioned step, when the calculated resource usage rate does not reach the first reference usage rate when it is compared with a first reference usage rate that is a reference for starting audit execution of the resource, It is determined whether or not a second reference usage rate serving as a reference for switching the mode of the usage rate measurement set in advance has been reached. If the second reference usage rate has not been reached, the resource usage status information is captured, A step of generating the resource usage information at each time of capturing and releasing the resource when the resource usage information is generated at a predetermined cycle set in advance instead of each time the resource is released and the second reference usage rate is reached; Can be.
[0009]
Further, when the reference usage rate (or the first reference usage rate) serving as a reference for starting the audit execution of the resource is 100%, and the number of resources being captured matches the total number of resources, the resource audit is performed. There can be a step of initiating execution.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
First, the outline of the present invention will be described. According to the present invention, in a resource control of an exchange which secures resources (memory blocks) with the occurrence of a call and releases the resources upon termination of the call, a proper use check of resources is performed in accordance with a resource usage rate, and illegal By forcibly releasing used resources, a call loss caused by all resources being busy due to improper use of resources due to a programming error or the like is promptly eliminated.
[0011]
More specifically, the resource user means issues a resource capture / release request to the resource management means. The resource management means manages the availability of the resources in the main storage device, and the resource measurement means measures the usage rate of the resources being captured by the resource management means. The resource measuring means holds the usage rate for executing the audit, and when the usage rate reaches a predetermined usage rate, issues a request to execute the audit to the audit execution means. In this way, auditing according to the resource usage rate is enabled.
[0012]
Next, embodiments of the present invention will be described in detail with reference to the drawings.
[0013]
FIG. 1 is a block diagram of an exchange (electronic exchange) according to an embodiment of the present invention. In FIG. 1, an exchange 10 of the present embodiment includes a main storage device (memory) 12 for storing various programs and data, and a central processing unit for controlling (software control) each section in the exchange in accordance with the programs and data in the main storage device 12. (CPU) 11. The central processing unit 11 executes a resource user unit 111 that uses resources (memory blocks), a resource management unit 112 that manages the availability of resources, a resource measurement unit 113 that measures the resource usage rate, and performs an audit. And an audit execution unit 114.
[0014]
In addition, the exchange 10 has circuits and means for connecting to subscribers and other exchanges and controlling outgoing calls, telephone calls, incoming calls, and the like, in addition to the above-described units, but is not directly related to the present invention. Detailed description is omitted.
[0015]
The resource user unit 111 performs processing using a resource in the main storage device 12 when a call from the exchange occurs. The resource user unit 111 requests the resource management unit 112, which manages the number of mounted resources and the availability of the resources, to acquire the resources, secures the resources, and holds the resource numbers. When the resource becomes unnecessary, the resource user unit 111 requests the resource management unit 112 to release the resource and deletes the number of the held resource.
[0016]
The resource management unit 112 sets the resource in use state when the resource is captured, and transitions to the unused state when releasing the resource. The resource management unit 112 notifies the resource measurement unit 113 each time the state changes.
[0017]
The resource measuring unit 113 sets in advance a predetermined usage rate (a reference usage rate that is a reference for starting the audit execution of the resource) to be notified to the audit execution unit 114. The resource measurement unit 113 counts the number of busy states notified from the resource management unit 112, and notifies the audit execution unit 114 when the number reaches a predetermined usage rate set in advance.
[0018]
The audit execution unit 114 checks whether or not the resource in use by the resource management unit 112 is in use by the resource user unit 111, and issues a release instruction to the resource management unit 112 if the resource is unused (illegal use). .
[0019]
Next, the overall operation of the present embodiment will be described in detail with reference to FIG.
[0020]
First, when a resource is required in a process when a call is generated in the exchange 10, the resource user unit 111 requests the resource management unit 112 to capture the resource. Upon receiving the resource capture request, the resource management unit 112 captures the resource and blocks it. The resource user unit 111 holds the number of the captured resource, and the resource can be used. When the secured resources are no longer needed, the resource user unit 111 requests the resource management unit 112 to release the resources. Upon receiving the resource release request, the resource management unit 112 releases the resources and makes them free. Such resource capture (and release) is processed in parallel as needed (step S100 in FIG. 2).
[0021]
The resource measurement unit 113 causes the resource management unit 112 to notify the number of mounted resources and the number of blocked resources (the number of captured resources) as resource usage information each time the resource is blocked or released (S101).
[0022]
Based on the notified data (resource usage status information), the usage rate (number of blocks / number of blocks) of the used (closed) resources held by the resource management unit 112 is calculated (S102).
[0023]
The calculated usage rate of the resource is a reference rate that is set in advance in the resource measurement unit 113 and serves as a reference for starting the execution of the audit of the resource that is being used illegally in order to prevent a call loss caused by a resource busy ( It is determined whether or not the reference usage rate has been reached. However, this reference usage rate is set to an arbitrary value of 100% or less.
[0024]
If the calculated usage rate has reached the reference usage rate for starting the execution of the audit, the resource measurement unit 113 issues an audit execution request to the audit execution unit 114 (S103).
[0025]
When the audit execution unit 114 receives the audit execution request notification, the resource management unit 112 closes the resources, but the resource user unit 111 notifies the resource management unit 112 of unused resources (illegal resources). The resource release is requested, and the unauthorized resource is released (S104).
[0026]
The processing of steps S100 to S104 described above is repeated.
[0027]
Next, a description will be given using a specific example. Here, it is assumed that the number of mounted resources is 200, and the usage rate (reference usage rate) of the resource for performing the audit is set to 90%.
[0028]
Resources are captured from the resource user unit 111 to the resource management unit 112, and the number of actually blocked resources is set to 180, and the resource measurement unit 113 is notified. When calculating the resource usage rate, the resource measurement unit 113 makes an audit request to the audit execution unit 114 because the usage rate is 90% and has reached the usage rate for executing the audit.
[0029]
Assuming that the reference usage rate is 100%, an audit request is issued to the audit execution unit 114 in a resource busy (all busy) state in which the number of mounted resources (in this case, 200) and the number of captured resources (the number of blocked resources) are the same. It will be.
[0030]
Next, another embodiment of the present invention will be described in detail with reference to the operation flowchart of FIG.
[0031]
As in the processing step S100 of FIG. 2 described in the above embodiment, when a resource is required in the processing when a call is generated in the exchange 10, the resource user unit 111 causes the resource management unit 112 to capture the resource. Request. Upon receiving the resource capture request, the resource management unit 112 captures the resource and blocks it. When the secured resources are no longer needed, the resource user unit 111 requests the resource management unit 112 to release the resources. Upon receiving the resource release request, the resource management unit 112 releases the resources and makes them free. Such resource capture (and release) is processed in parallel as needed (step S200 in FIG. 3).
[0032]
In this example, the operation modes of the resource management unit 112 and the resource measurement unit 113 include two modes depending on the difference in the usage rate measurement method, that is, the state transition every time measurement mode and the cycle measurement mode. In the initial state, the measurement mode is set for each state transition.
[0033]
The resource management unit 112 under the state transition every time measurement mode measures the resource blockage / release (state transition), the resource implementation number and the resource blockage number (capture number) as resource use status information. The notification is made to the unit 113 (S201).
[0034]
The resource measurement unit 113 calculates the resource usage rate, which is the ratio of the number of captured resources in the total number of resources, based on the notified resource usage information (S202), and the calculated resource usage rate is set in advance. It is determined whether a first reference usage rate (a first predetermined value, for example, 90%) serving as a reference for starting audit execution of the resource has been reached (S203).
[0035]
If the first predetermined value has not been reached in the processing of step S203 (NO side of S203), the resource measurement unit 113 further uses the second reference use as a reference for switching the mode of the usage rate measurement set in advance. It is determined whether the rate (second predetermined value, for example, 60%) has been reached (S210).
[0036]
In the process of step S210, if the second predetermined value has not been reached (NO in S210), the resource measuring unit 113 changes the mode of the usage rate measurement from the state transition every time measurement mode to the cycle measurement mode, Notify the resource management unit 112.
[0037]
The resource measurement unit 113 in the cycle measurement mode sends a resource usage status information transmission request to the resource management unit 112 at a predetermined cycle set in advance.
[0038]
The resource management unit 112 under the cycle measurement mode performs resource measurement at the time when a resource use status information transmission request is received from the resource measurement unit 113, rather than every time a resource is blocked or released. It is sent to the unit 113 (S211). The resource measurement unit 113 repeats the processing from step S202.
[0039]
In the process of step S210, if the second predetermined value has been reached (YES side of S210), the resource measuring unit 113 returns the mode of the usage rate measurement from the cycle measurement mode to the state transition every time measurement mode, and Notify the management unit 112. The resource management unit 112 returns control to notify the resource measurement unit 113 of the resource usage information each time the resource is closed or released (S200) (S201).
[0040]
When the first predetermined value has been reached in the processing of step S203 (YES side of S203), the resource measuring unit 113 sets the state transition every time measurement mode to the state transition mode when the usage rate measurement mode is the cycle measurement mode. And an audit execution request is made to the audit execution unit 114.
[0041]
When the audit execution unit 114 receives the audit execution request notification, the resource management unit 112 closes the resources, but the resource user unit 111 notifies the resource management unit 112 of unused resources (illegal resources). The resource release is requested, and the unauthorized resource is released (S104).
[0042]
The processes in steps S200 to S211 are repeated.
[0043]
Also in the present embodiment, if the reference usage rate is 100%, the resource measuring unit 113 executes an audit in a resource busy (all busy) state in which the number of mounted resources and the number of captured resources (the number of blocked resources) are the same. An audit request is made to the unit 114.
[0044]
As described above, in the present embodiment, if the resource usage rate is considerably lower than the value at which the audit should be started, the resource usage rate is checked not at every resource state transition but at a predetermined cycle interval. Therefore, the processing load on the system can be reduced.
[0045]
In any of the above-described embodiments, the audit target resource is described as a resource that is captured when a call is generated and released when the call is terminated. However, the present invention is not limited to this. The present invention can be applied to all resources used in the processing in the exchange.
[0046]
【The invention's effect】
As described above, according to the present invention, each time a resource is captured or released, the resource is audited according to the resource usage rate, so that a call loss occurs due to a resource busy due to the improper use of the resource due to some factor. This can be prevented promptly.
[0047]
In addition, according to the degree of the resource usage rate, by checking the resource usage rate at predetermined intervals, rather than every time the resource is captured or released, the processing load on the system can be reduced. it can.
