The present invention relates to a service level guarantee system and method for automatic collection of performance data, and more particularly, PM-OM (PM-) for collection of performance data related to guarantee of communication quality in asynchronous transmission mode (ATM). The present invention relates to a service level guarantee system for automatically collecting performance data and a method thereof, by automatically setting OAM) functions to collect performance data, so that communication quality can be more efficiently guaranteed without operator intervention.

Recently, not only providing a communication service but also ensuring a quality of a provided communication service has emerged as an important issue. The service quality evaluation is performed on various checks related to the quality of the communication service, for example, the communication speed, the response rate to subscriber inquiries, and the performance of the opening / failure recovery on time, thereby improving the satisfaction of the subscriber and the overall quality of the communication service. Efforts are being actively made.

Quality assurance for telecommunications services is currently divided into three quality areas: opening quality, failure quality and communication quality. In addition, the communication service system includes various management systems for performing work in each quality field, for example, an opening management system, a failure management system, a network management system, and a plurality of management systems according to a request for completion of subscription from a subscriber. There is a service level agreement system for monitoring whether work is being performed.

Herein, the service level agreement system will be described in more detail. The service level guarantee system may include an opening management system, a failure management system, and a network management so that the service level according to the subscriber's subscription (commitment) can be guaranteed. It refers to a system that monitors whether a system, etc., fulfills an offer, and analyzes the cause of the failure if it does not, so that quality assurance can be properly performed.

For example, an opening management system sends a communication service opening request from a subscriber (eg, a company) to a service level guarantee system, and informs a worker (person) to perform an actual opening work. After completion of the opening work, the subscriber and the service level guarantee system are notified of the completion of the opening. Here, the service level guarantee system checks the subscription (ie contracted quality assurance level) with the subscriber and schedules the service to be opened on the scheduled opening date, for example, within 2 days after receiving the opening information. If a period of time has passed but no notification has been received from the opening management system, a pre-warning message is sent to the appropriate department (ie the responsible worker).

In another example, the failure management system receives failure information from the subscriber (eg, telephone line cuts due to sewer pipe laying) and informs the service level guarantee system and the worker, and then the subscriber and service level as the worker completes the recovery. Notify the guarantee system of the completion of the fault recovery. Here, the service level guarantee system checks whether or not the completion of the failure recovery after two hours if the recovery is completed within 3 hours after receiving the failure information, for example, based on the subscription with the subscriber ( If you are not notified of the completion of a failure recovery, send a pre-warning message to the responsible department (the responsible worker) to ensure that the recovery can be completed within the agreed time.

In another example, the network management system (NMS) performs configuration of various communication equipments (eg, routers, switches, servers), collection of performance data, and fault monitoring to ensure communication quality. That is, it controls (commands) communication equipment such as an exchange according to requests from various management systems. Here, the communication quality is guaranteed by various evaluation items such as packet delivery delay, packet loss rate, upload / download speed (highest / average / lowest rate), and the like. In recent years, the company has entered a competitive era for high-quality services, such as the provision of a system to compensate for falling below the agreed minimum rate.

On the other hand, asynchronous transmission mode (ATM) is a broadband integrated information network (B-ISDN), a high-speed, parallel by transmitting a header (including the destination label) and information in a cell of fixed size (53 bytes) Processing is possible. Here, the cell includes a user cell for transmitting / receiving various kinds of information such as voice and video, and a repair cell (OEM cell) having the same destination label as the user cell. In the asynchronous transmission mode, the detection interval of the bit error can be detected using a repair cell (OHM cell). In particular, in the asynchronous transmission mode (ATM), the PM-OAM function is provided. By setting the PM-OAM function, various performance data regarding network resources and connections can be collected. And through this analysis work can ensure the communication quality.

However, in the related art, an operator has to manually set and manage a PM-OAM function provided in an asynchronous transmission mode (ATM). That is, conventionally, due to the manual operation of the operator for the PM-OAM function, there is a problem in that work efficiency is lowered and it is difficult to completely guarantee communication quality.

The present invention has been proposed to solve the above problems, and provides a PM-PM (PM) provided in the asynchronous transmission mode (ATM) in response to the request for subscription completion from the subscriber to ensure the communication quality in the asynchronous transmission mode (ATM) -OAM) to automatically collect the performance data related to the communication quality by setting the function automatically, so that a more efficient communication quality management can be achieved without operator intervention, and a service level guarantee system for the automatic collection of performance data The purpose is to provide.

That is, according to the present invention, the PM-OAM function provided by the asynchronous transmission mode (ATM) is automatically set according to the type of subscription completion request from the subscriber to periodically collect performance data for guaranteeing communication quality. Therefore, the object of the present invention is to provide a service level guarantee system and method capable of reducing the operator's workload and ensuring the communication quality more completely.

Other objects and advantages of the present invention can be understood by the following description, and will be more clearly understood by the embodiments of the present invention.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings, whereby those skilled in the art may easily implement the technical idea of the present invention. There will be. In addition, in describing the present invention, when it is determined that the detailed description of the known technology related to the present invention may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

According to the present invention, performance data accumulated periodically by setting a communication service management function provided by a communication equipment (ATM equipment), that is, PM-OAM function, to guarantee communication quality in an asynchronous transmission mode (ATM). It is performed automatically without the intervention of the operator (operator of the service level guarantee system) in collecting the data, so that efficient communication quality management can be achieved.

1 is a configuration diagram of an embodiment of a service level guarantee system for automatically collecting performance data according to the present invention.

As shown in FIG. 1, the service level guarantee system for automatically collecting performance data according to the present invention includes a PM-O according to the requested type of completion of the subscription as the service completion message is received from an external subscription management system 10. PM-OAM automatic configuration module 21, network management to generate the PM-OAM setting message and transmit to the external network management system 30 so that the PM-OAM function is set The PM-OAM setting result processing module 22 for receiving and storing the processing result for the PM-OAM setting message from the system 30, and the PM-OAM function The performance data accumulated as set is collected periodically from the external performance management server 40 (for example, every 15 minutes) to process the performance analysis to ensure communication quality. It includes a performance data collection module 23.

At this time, the PM-OAM automatic configuration module 21 receives the subscription completion message from the external subscription management system 10 in order to activate or deactivate the PM-OAM (PM-OAM) function A setting message is generated and sent to the network management system 30.

That is, the PM-OEM automatic setting module 21 analyzes the subscription completion message received from the subscription management system 10 to find a corresponding message type (New / Delete / Change). Here, the subscription completion message refers to a message generated by the subscription management system 10 in response to a subscription completion request from a communication service subscriber (eg, a company), and includes various types of subscription completion (eg new, suspension of use, change of contract). Can be classified accordingly (according to the classified subscription completion type) and have a predetermined message type (New / Delete / Change).

In addition, the PM-OAM automatic setting module 21 determines whether to activate the PM-OAM function according to the found message type (New / Delete / Change), and sets the PM-OAM accordingly. Create and send a message. For example, if the message type is New, the segment information of the subscriber trail is collected to generate a configuration message for activating the PM-OAM function, and the message type is changed. ), It generates a setting message for activating the PM-OAM function by collecting section information of the subscriber trail and confirming that a change has occurred by comparing with the existing section information. If the type is Delete, it generates a setup message for deactivating the PM-OAM function.

In addition, the PM-OH setting result processing module 22 stores the result of processing the PM-OME setting message from the external network management system 30. In more detail, when the PM-OAM function is successfully set, the processing result of the PM-OAM setting message received from the network management system 30 is checked. On the other hand, if the setting of the PM-OAM function fails, the number of attempts (the number of transmissions of the PM-OEM setting message) is checked and the same setting is performed if the preset limit number (eg, 2 times) is not exceeded. The P-OEM automatic configuration module 21 requests to retransmit the message (secondary transmission), and if the limit number is exceeded, does not attempt to retransmit the configuration message (secondary transmission) and stores the result as it is. At this time, the processing result of the PM-OEM setting message may be stored in a database.

In addition, the performance data collection module 23 periodically connects to the external performance management server 40 at intervals of, for example, 15 minutes to collect performance data for ensuring communication quality. Here, the performance data is data accumulated automatically in the performance management server 40 as the PM-OAM function provided by the communication network (ATM network) is activated. In addition, the performance data collection module 23 processes the collected performance data so as to perform an analysis operation for ensuring communication quality.

Meanwhile, the subscription management system 10 generates a subscription completion message according to a request for completion of various types of subscriptions from a subscriber of a communication service (for example, a company), and automatically sets the PM-OEM module of the service level guarantee system 20. (21). That is, in order to automatically set the PM-OAM function of the communication network (ATM network) by the service level guarantee system 20 according to the request for subscription completion from the subscriber to generate and send a subscription completion message do. The completion of each type of subscription will be described in more detail with reference to FIG. 2 to be described later.

In addition, the network management system 30 is a system for configuration, performance, and failure management of various equipments of the communication network (ATM network) from the PM-OEM automatic configuration module 21 of the service level guarantee system 20 The PM-OAM setting message is received and a setting command for the PM-OAM function, that is, an activation command or a deactivation command, is sent to the exchange (not shown). Thereafter, it is checked whether the PM-OAM setting command succeeds and transmits the result to the PM-OAM setting result processing module 22 of the service level guarantee system 20.

In addition, the performance management server 40 accumulates various performance data for a communication network (ATM network).

FIG. 2 is a diagram illustrating an embodiment of a PM-OEM setting message according to a subscription completion type in a service level guarantee system according to the present invention.

As shown at 25, subscription completion messages received from subscription management system 10 may be classified into various subscription completion types. For example, new, unused revival, suspended reinstatement, termination, suspension of use, suspension, contract change, line history change, branch number change, and the like. At this time, the various types of subscription completion as described above can be largely classified into three fields, there is a message type (New / Delete / Change) matching corresponding to each field as shown in "26". That is, different message types are matched according to the subscription completion type of the subscription completion message. For example, subscription completion types such as new and deprecated revival match new message types, and subscription completion types such as revocation and deprecation correspond to delete message types. The subscription completion type, such as change, is matched to the change message type.

The subscription completion type and the message type according to the above are the criteria for determining whether to activate the PM-OAM function provided by a communication network (ATM network).

Figure 3 is a flow diagram of an embodiment of the automatic PM-OM setup in the service level guarantee system according to the present invention.

First, the PM-AUM automatic setting module 21 receives the subscription completion message from the external subscription management system 10 (301) and analyzes the received subscription completion message to determine the message type according to the subscription completion type (New / Delete / Change) (302).

As a result of the message type determination 302, in the case of the new message type, a configuration message for activating the PM-OAM function of the communication network (ATM network) is collected by collecting section information of the subscriber trail (303). Generate (304) and transmit to external network management system 30 (305).

On the other hand, the message type determination result 302, in the case of a change (Change) message type is collected (306) the section information of the subscriber trail to determine whether or not changed compared to the existing section information (307). As a result of determining whether the section information is changed (307), if the section information is not changed, the process is terminated. If the section information is changed, the network management system 30 generates a setting message for activating the PM-OAM function. The process proceeds to steps 304 and 305 of FIG.

On the other hand, if the message type determination result 302, the delete message type generates a configuration message for the deactivation of the PM-OAM (PM-OAM) function (308), the generated configuration message is a network management system (30).

Thereafter, the PM-AUM automatic setting module 21 waits for receiving a new subscription completion message.

4 is a flowchart illustrating an example of a process of processing a PMS-OEM setting result in a service level guarantee system according to the present invention.

First, the PM-OH setting result processing module 22 receives a processing result of the PM-OME setting message from an external network management system 30 (401). In operation 402, it is determined whether the PM-OAM function is successfully set.

As a result of determining whether the PM-OAM setting succeeds (402), if it fails, it is determined whether the number of attempts (number of transmissions of the same setting message) exceeds a preset limit number (for example, two times). Determine (403). As a result of determining whether the limit is exceeded (403), if not exceeded, request the PMS-OHM automatic configuration module 21 to retransmit (secondary transmission) the same PMP-OH setting message to the network management system 30. In operation 401, the processing result of the PM-OH setting message is received. On the other hand, if exceeded, the processing result is stored as it is (405).

On the other hand, the result of determining whether the PM-OAM setting is successful (402), and if successful, proceeds to the process of storing the processing result (405).

Thereafter, the PM-OEM setting result processing module 22 waits for reception of a processing result for a new PM-OH setting message.

5 is a flowchart illustrating a method of collecting performance data in a service level guarantee system according to the present invention.

First, the performance data collection module 23 checks whether a log file exists as the communication service and the communication quality guarantee service are started (501).

As a result of checking the log file (501), if the log file exists, the final performance data collection time recorded in the log file is searched (502) to set the next scheduled performance data collection time (503). At this time, it can be set to collect performance data at regular time intervals. On the other hand, if the log file check result 501, the log file does not exist, the next scheduled performance data collection time is set to a predetermined time (for example, 0 o'clock) (504).

Thereafter, the performance data collection module 23 determines whether the sum of the spare time (for example, 30 minutes and 1 hour) in consideration of the set performance data collection scheduled time and performance data accumulation time is smaller than the current time ( 505). That is, it determines the current collection possibility of the performance data.

In the result of determining whether the performance data can be collected (505), when performance data can be collected (when the sum of the scheduled performance time and the free time is less than the current time), the performance accumulated in the meantime from the external performance management server 40 Collect data (506). That is, the PM collects performance data accumulated for the set port. The subscriber data of the communication quality guarantee service is separated from the collected performance data (507), and processed and stored to perform an analysis operation for ensuring communication quality (508). Thereafter, the performance data collection module 23 records the performance data collection time in a log file and sets the next scheduled performance data collection time. In addition, if an end event from the operator (operator of the service level guarantee system) occurs, it terminates.

On the other hand, if it is determined that the performance data collection is possible (505), when performance data collection is impossible (when the sum of the performance data collection scheduled time and the spare time is larger than the current time), the terminal sleeps (509). Thereafter, the process proceeds to step 505 of determining whether performance data can be collected.

As described through the above embodiment, the present invention is based on the control of the service level guarantee system 20 when a subscription completion request (for example, new, discontinued, contract change) occurs from a subscriber (for example, a company). By automatically enabling / disabling the PM-OAM function provided by the ATM network, performance data can be collected more efficiently and communication quality can be guaranteed without manual intervention of an operator.

As described above, the method of the present invention may be implemented as a program and stored in a recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.) in a computer-readable form. Since this process can be easily implemented by those skilled in the art will not be described in more detail.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the technical spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited by the drawings.

The present invention as described above, the PM-OAM (PM-OAM) function is automatically set in the asynchronous transmission mode (ATM) without the operator's intervention to collect the performance data, thereby ensuring the operational quality of the communication quality This has the effect of improving efficiency.

That is, according to the present invention, the PM-OAM function for collecting performance data in the asynchronous transmission mode (ATM) is automatically activated / deactivated according to the request for subscription completion from the subscriber, thereby reducing the operator's workload. There is an effect to increase the work efficiency.

Accordingly, there is an effect that can guarantee the communication quality more completely.
