The configuration is a performance management system 200, an upper layer system 201. An operator 202, an other processor 203, and a lower hierarchy system 210. [

The performance management system 200 includes an operation receiving unit 204, a performance monitoring activation processing unit 205, a threshold setting processing unit 206, a performance alarm processing unit 207, a data processing unit 208, and a performance alarm receiving unit 209 .

Here, the operation receiving unit 204 receives the performance monitoring activation operation from the upper layer system 201 or the operator 202 for the network elements or logical elements requiring performance monitoring, And if it is still inactive, it is stored and managed in the data storage unit. The performance monitoring activation processing unit 205 determines activation of a performance monitoring function for an active component or a logical resource and processes the activation of each function required for the component. The threshold value setting processing unit 26 sets a proper value to be a reference when there is a reference point when a network element generates a performance alarm. This is set to an appropriate value based on the situation of the operator and the entire network.

When the performance alarm is generated, the performance alarm processor 207 transmits the performance information and the performance alarm to the related system and the processor, notifies the operator of the performance information, and informs the logical resource of the network resource component or the network of alarm To handle performance alerts such as preventing future performance degradation or resolving the cause of performance degradation in the future.

The data processing unit 208 stores and manages all information data related to performance alert activation, performance alert data, and all data generated during performance processing. The performance alarm receiving unit 209 receives and manages performance alerts generated in the network elements and the lower layer. The lower layer system 210 controls the direct network element. The lower layer system 210 processes the activation of the performance monitoring and reports performance alerts generated by the network elements to the performance monitoring processor.

FIG. 3 is a method for activating performance data collection according to the present invention. First, a performance data collection activation command is issued to an upper layer or a network element in which an operator needs performance monitoring. At this time, the data acquisition activation command is received by the operation receiving unit 204 and stored in the data storage unit (not shown) (S303). Then, the information of the data processor 208 is searched to determine whether an item for activating a function for a performance test is currently activated (S304). At this time, if the item to be activated as a result of the determination in step S304 is currently active, the operator is notified of the item.

If it is determined in operation S304 that the item to be activated is not currently active, that is, if the item is in an inactive state, it is determined in operation 305 whether the operation to be activated is a function. If it is determined in operation S305 that the function to be activated is a traffic measurement, the parameter is changed and stored (S309) so as to lower the operation to the lower layer (S309), and then the corresponding processing routine (S312) is performed.

Here, the processing routine step S312 first changes the information that activates the traffic data measurement to the relevant logical network element (S312-a), selects a lower layer network management system that manages a point of the component to be actually activated , And activates the function to the component of the lower sub-network (S317).

On the other hand, if it is determined in operation S305 that the function to be activated is the user parameter control (S307), the parameter is changed and stored in S310 so as to lower the operation to the lower layer (S310) ).

Here, the processing routine step S313 first changes the information to enable the user parameter control measurement to the related logical network element (S313-a), and selects a lower layer network management system that manages the point of the component to be actually activated (S313-b), and activates the function of the component of the lower-level subnetwork (S318).

On the other hand, if it is determined in operation S305 that the function to be activated is the activation of the performance measurement (S308), the parameter is changed and stored (S311) so as to lower the operation to the lower layer (S311) do.

Here, the processing routine step S314 first changes the information to activate the user parameter control measurement on the relevant logical network element (S314-a). To do this, the OAM (Operation And (S314-b) for selecting a lower layer network management system for managing a component point for inserting a cell into a cell, and extracting performance measurement data from the cell for operation and maintenance (OAM) A lower layer network management system that manages a component point is selected (S314-c). Then, an operation for activating the function is actually sent to the corresponding network element (S320).

FIG. 4 illustrates a performance data collection / deactivation method according to an embodiment of the present invention. Referring to FIG. 4, a performance data collection deactivation command is issued to an upper layer or a network element requiring an operator to monitor performance. The operation receiving unit 204 receives the command and stores the data in a data storage unit (not shown) (S403). Then, the information of the data processing unit 208 is searched and it is determined whether an item to disable a function for a certain performance check is currently activated (S404). At this time, if the item to be deactivated as a result of the determination in step S404 is currently inactivated, it is notified to the operator.

If it is determined in operation S404 that the item to be deactivated is not currently deactivated, that is, if it is in an active state, it is determined in operation 405 whether the operation to be deactivated is a function. If it is determined in operation S405 that the function to be deactivated is a traffic measurement, a parameter is changed and stored in a lower layer to perform an operation (S409), and then a corresponding processing routine S412 is performed.

In step S412, the information is changed to deactivate traffic data measurement to the related logical network element (S412-a), and a lower layer network management system that manages a point of a component to be actually deactivated is selected (S412-b ), The function is disabled for the component of the lower sub-network (S417).

On the other hand, if it is determined in operation S405 that the function to be deactivated is for user parameter control (S407), the parameter is changed and stored in S410 corresponding to the lower layer operation (S410) .

In step S413, first, the information is changed to disable the user parameter control measurement to the related logical network element (S413-a), and a lower layer network management system that manages a point of the component to be actually deactivated is selected S413-b), the function is disabled to the component of the lower-level subnetwork (S418).

On the other hand, if it is determined that the function to be deactivated in step S405 is inactivated (S408), the parameter is changed and stored in step S411 so that the operation is performed in the lower layer (S411) .

In step S414, information is changed to disable the user parameter control measurement to the related logical network element (S414-a). To do so, first, an operation and maintenance (OAM) cell (S414-b), extracts the operation and maintenance (OAM) cell and extracts the performance measurement data from another component point A lower layer network management system for managing the lower layer network management system is selected (S414-c). Then, an operation for disabling the function is sent to the corresponding network element (S420).

FIG. 5 is a flowchart illustrating a method for changing the performance threshold of a network element according to an embodiment of the present invention. Referring to FIG. 5, operations for changing performance threshold values are performed on an upper layer or a network element requiring an operator to perform a performance test. Upon receiving this operation (S502), the data is first stored in the data storage unit (S503), and the information of the data processing unit 208 is searched to compare the threshold value of the performance item to be changed at present with the existing threshold value And determines whether or not they are the same value (S504).

At this time, if the threshold value of the performance item to be changed is equal to the existing threshold value as a result of the determination in step S504, the operator is not notified further but notifies the operator.

If it is determined in step S504 that the threshold value of the performance item to be changed is not the same as the existing threshold value, it is determined in step S505 whether the current performance threshold value is to be changed. If it is determined in step S505 that the number of performance thresholds to be changed is an item for traffic, data of a threshold number to be changed is changed (S509), and a sub-NMS for managing a component to be modified is searched (S512) To change the number of performance thresholds (S516).

If it is determined in step S505 that the number of performance thresholds to be changed is a user parameter, data of a threshold number to be changed is changed (steps S507 and S510), and a sub-NMS that manages a component to modify the threshold number is searched (step S513) . And instructs to change the performance threshold number of the component (S517).

If it is determined in step S505 that the number of performance thresholds to be changed is for the performance data measurement, the data of the threshold number to be changed is changed (S508 and S511), and the sub-NMS for managing the sub- (S514, S518) to find the sub-NMS that manages the point where the OAM cell is terminated.

FIG. 6 shows a performance alert monitoring activation and a threshold number change operation with guaranteed transaction. First, the performance monitoring processor activates a performance monitoring function for performance checking from the upper layer system 201 or the operator 202, (Operation S603). In operation S603, data for processing is combined with information on the operation received in operation S603, and stored in the corresponding storage (SS05). In step S606, the routine for each operation processing is determined after step S603. If the processing routine is determined in step S606, information on the related network element is changed in step S607. At this time, if the information change of the component is processed in step S607, the information is stored in the corresponding storage and the changed information is prepared to be stored in the storage (S609).

On the other hand, in order to activate a related point, a related point is found and a process for activating the function for the point is performed (S608). At this time, all the information generated in the step S608 and the changed information are prepared to be stored in the storage ). Then, the lower layer network management system that manages this point is determined and the operation is sent.

In operation of the lower layer network management system, the performance processing client is notified of the success or failure of the performance monitoring activation function (aa). Then, the performance monitoring client checks whether the processing result is properly processed in the lower layer network management system or if the processing is unsatisfactory due to processing abnormality (bb). At this time, if the check result has been successfully processed, it is instructed to store the prepared data in the storage (cc). If the test is unsuccessful, instruct the repository to discard any information it has prepared to store (dd).

As described in detail above, according to the present invention, in the asynchronous transmission mode high-speed communication network management system configured hierarchically and taking into account ease of network management and expansion, a performance monitoring function for performance testing is activated and deactivated And a method for changing the performance thresholds are described. First, if a command issued by the upper layer is verified, if the same command is issued, the operation is terminated immediately without propagating the operation to the lower layer, thereby shortening the time for the operation processing. In this way, the reliability of network operation is improved for the operator who operates the network by preventing inconsistent operation of the operation in the middle.

It will be apparent to those skilled in the art that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. You should see.
