Intelligent Network Application Protocol Operation Statistics Data Processing Method in Intelligent Information System {Method of processing for INAP operation statistics on AIN IP}

The present invention relates to a method for processing INAP operation statistics data in an advanced information network (AIN IP: Intelligent Peripheral), and more particularly, to collecting intelligent network application protocol (INAP) operation statistics data. In order to avoid affecting call processing and resource service processing time, measurement data is collected in the form of low data using the measurement library and stored in local memory. The present invention relates to a method of processing statistical data of INAP operation that calculates and formats the data in the required format and delivers the data to the operator.

The intelligent information providing system is a system that provides resources that are more centralized in one system than providing services by distributing them to special resources or multiple network elements that are difficult to possess in other network elements of the next-generation intelligent network. The operation management technology of the intelligent information providing system consists of three fields: operator matching function, data processing function, measurement and statistical processing function, and the present invention is included in the measurement and statistical processing function.

Intelligent Network Application Protocol (INAP) is a communication protocol for transmitting and receiving information between Service Switching Point (SSP), Service Control Point (SCP) and Intelligent Peripheral (IP) in next-generation intelligent network. It operates on the signal network protocol SS No.7 stack. In the existing early intelligent network, an application service element (ASE) was developed for each intelligent network service to communicate between SSP and SCP through the common line signaling network protocol SS No.7. Therefore, we developed an application service element that can handle the service whenever a new intelligent network service is provided. However, INAP of next generation intelligent network is independent of intelligent network service because it provides services by combining service independence building blocks (SIBs), which are service independent building blocks necessary for communication between networks. In particular, the intelligent information providing system is a system that provides a corresponding resource according to an INAP operation without distinguishing the intelligent network service, and calculates statistical data for each INAP operation. INAP operations handled by intelligent information provision systems include user information collection (PCUI: PromptAndCollectUserInformation), message recording (PRM: PlayRecordingMessage), announcement (PA: PlayAnnouncement), message deletion (EM: EraseMessage), and operation cancellation (CANCEL). .

In AIN IP, measurement and statistics functions are divided into immediate statistics by operator's request and periodic statistics by system's request, which are generated from the entire AIN IP including hardware and software. It is a function that calculates statistical data for each item by measuring all meaningful events.These data can be used to identify the status of the system, performance evaluation, mid- to long-term design, distribution of usage by special resources, system maintenance, and installation of AIN IP. It should be able to provide the information necessary for the distribution of income between stations and the installation of AIN IP. The collected INP operation statistics are collected by the type of the INP operation received from the service control system (SAP), the number of times received, the number of successes, the number of successes processed, the number of occurrences by the failure cause, and the operation processing time (resource). The provision time) is output in the form of text and graphics from the operator terminal.

Statistical functions that collect information about events that occur during operation in the system are essential for the analysis of the unique or important functions of the system. The question of how to implement these functions in the target system or what information is collected depends on the characteristics of the target system.

In the service control function of the intelligent information providing system, collecting and processing all events generated during processing of INAP operation received from SCP and delivering them to the operator, it should not affect call processing and resource service processing time, and analyze network traffic, Through the analysis of execution time by operation, it should be able to be utilized for mid to long term network installation plan, system expansion, and performance evaluation.

Accordingly, an object of the present invention is to provide an INAP operation statistical data processing method which can minimize the change of the measurement target during collection and minimize the load on the system by collecting information that can occur in one event at a time.

In order to achieve the above object, the present invention provides a method for processing statistical data of an intelligent network application protocol (INAP) operation in an intelligent information providing system, wherein the measurement and statistics are generated when an intelligent network application protocol operation measurement event is generated in a service control (SCP) block. Calling a corresponding library for each operation type in a data collection library (MSLC) block to store library data received for each operation in a memory; When the operator requests to perform the statistics through the input window of the graphical user interface, the second step of analyzing the statistics request command in the operator matching block and transmitting information necessary for collecting INAP operation statistics to the measurement and statistical data processing (MSDP) block; ; In the measurement and statistical data processing (MSDP) block, information about the measurement start time, measurement execution time, and measurement repetition time received from the operator matching block is analyzed, and it is determined whether to perform statistical work based on the analyzed information. Registers necessary information in a related table, and transmits a data collection instruction to a measurement data collection (MDGS) block to generate statistical data by reading data stored in the memory for the measurement repetition frequency during the measurement execution time; A third step of calculating the measurement data for each unit of time by calculating the final value-initial value according to the time information managed for each item collected in the step and generating the statistical information to meet the INAP operation statistical information; A fourth step of outputting the calculated statistical data in graphic or text form according to the set input window, and converting and outputting the statistical data generated in the third step into a form requested by an operator; And a fifth step of deleting the statistical work management table managed for performing the statistical work when the measurement execution expires.

The present invention collects measurement data in the form of low data using a measurement library, stores it in a local memory, reads the corresponding information in a given time unit, and calculates statistical data in a required form. By formatting and passing it to the operator, the collection of INAP operation statistics data does not affect the call processing and resource service processing time. In addition, it provides the maximum information needed by the operator in the expression of data so that the entire system can be analyzed with a single statistical item, and the format required by the operator (text, pie, bar). Since it is output according to the graph, it can be very useful for analyzing the results and comparing the analysis status of AIN IP and manganese service provision.

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

1 is a hardware configuration diagram of an intelligent information providing system to which the present invention is applied.

As shown in the figure, the AIN IP includes a Specialized Resource Main Processor (SRMP) 101 and a Specialized Resource Switch (SRS) 102 serving as a server of the intelligent information providing system. ) And a Specialized Resource Unit (SRU) 103.

The main processor (SRMP) 101 is connected to the graphical user interface 104 and provides an operator matching function and a maintenance function for handling operator message input / output functions of an intelligent information system (AIN IP) using a workstation. .

Special resource unit (SRU) 103 is a complex frequency code (DTMF: Dual Tone Multi-Frequency) collection, tone transmission, fixed / edit / on-demand announcement provided by the intelligent information system (AIN IP), The system consists of a special resource board that provides voice recording and functions to control it. It is implemented using a Pentium Pro-class personal computer (PC).

The special resource switch (SRS) 102 was developed by changing the RASM exchanger of the integrated telecommunications network electronic switch (TDX-10 (trade name)), and is serviced by a switch access and management processor (SAMP). It performs most of the functions for providing special resources in AIN IP, such as control, call processing, intelligent network application protocol (INAP), SS No.7 protocol, operation and maintenance.

2 shows a software block structure diagram for performing an INAP operation statistics data collection and transfer process.

The function of collecting and transferring the INAP operation statistics data is composed of data collection and storage function, data management function, data processing and delivery function.

In FIG. 2, the service control block 201 functions to analyze the received INAP operation from the service control system (SCP), determine whether the corresponding resource is available, and provide the resource. The service control block 201 is also a function of controlling all operations on resources provided by the AIN IP, which is a main function of evaluating the performance of the AIN IP together with the call processing block. Therefore, it should not affect resource service processing time and performance in order to collect statistical data on resource services from the service control block. The measurement library related to the present invention includes three libraries: IPMD_SCPrim (), which collects the corresponding information when the INAP operation is transmitted and received, IPMD_RscSucc (), which collects the information when the resource provision is successful, and IPMD_OprFail (), which collects the information when the resource provision fails. These libraries are managed by the MSLC 202 described below. That is, when a measurement event occurs in the process of receiving an INAP operation and providing a resource, the resource service control function calls the library.

Referring now to the above process, first, the data collection function (data writing function) is an intelligent peripheral (IP) corresponding to the INAP operation transmission and reception and INAP operation from the service control block 201 that processes the INAP operation received from the SCP When a measurement event for resource provision occurs, the MSLC 202, which is a data collection library block, calls a corresponding library to collect it from the library block and stores it in local memory as low data. Or continually while the system is operating, regardless of system requirements.

The data management function (data reading function) reads the data necessary for INAP operation statistics from the raw data stored in the MSLC library, which is the measurement data gathering for AIN IP service (MDGS) block 203, which is a measurement data collection block, and processes the data. This function transmits to Measurement and Statistics Data Processing (MSDP) block 204, which is a measurement and statistical data processing block, which manages the collection information so that the information can be provided by the time required by the operator or by the time required by the system. .

The data processing and delivery function (data formatting and presentation function) analyzes the received statistics execution command from the operator and processes the collected information for the time required by the MDGS block 203 for the INAP operation statistics. Or, it processes the collected information for the time required by the system and delivers it to the operator. More specifically, when the MSDP block 204 receives a statistics request from the operator matching block 205, the MSDP block 204 recognizes that the received statistics are for the INAP operation, and receives from the operator matching block 205 through performing the statistics. Analyze the information. In other words, it analyzes the measurement start time, measurement execution time (measurement time), information about the number of measurement repetitions, etc. (if the operator designates it, the statistics are performed with the designated input value. Perform statistics), and determine whether statistics can be performed based on the analysis information, and register necessary information in a related table. The data acquisition command is sent to the MDGS block 203 to generate statistical data by reading data stored in the local memory for the number of measurement repetitions during the measurement execution time. Based on the time information managed by the items collected in the measurement library, the final value-initial value is calculated to calculate the measurement data for each measurement unit hourly, and generate statistical data to match the INAP operation statistics.

In this case, the operator may select an output format, and the AIN IP delivers the calculated statistical information in a format requested by the operator, that is, a graphic (pie, bar, graphic) or text.

3 is a flowchart illustrating a procedure of collecting INAP operation statistics data by an operator request.

The measurement target block for the INAP operation statistics is a service control block. The types of INAP operation to be measured are user information collection (PCUI), message recording (PRM), announcement (PA), message deletion (EM) and operation cancellation (CANCEL). Measure it. Statistical data collection is performed continuously while the AIN IP is running, so the collected data is stored in local memory. Looking at the process thereof with reference to the drawings as follows.

When the event for the INAP operation transmission and reception occurs in the service control block through the start 10 of the process (11), the library is called according to the INAP operation type (PCUI, PRM, PA, EM, CANCEL) (12). That is, when an INAP operation is received from the SCP, which is a service control system, the INAP operation reception library "IPMD_SCPrim ()" is called (13), and the library information received for each INAP operation in the MSLC block is stored in the memory (14). When the SCP sends the INAP operation, it calls the INAP operation transmission library "IPMD_SCPrim ()" (15), and stores the library information received for each INAP operation in the MSLC block in memory (16). Upon successful execution of the INAP operation, the " IPMD_RscSucc () ", which is an INAP operation execution success library, is called (17), and the library information received for each INAP operation in the MSLC block is stored in the memory (18). When the INAP operation fails, the INAP operation failed library "IPMD_OprFail ()" is called (19), and the library information received for each INAP operation in the MSLC block is stored in the memory (20). While the AIN IP is operating, operation data is collected through the above process, and when the system is stopped, the data collection operation is terminated (21).

4A to 4D are flowcharts illustrating a process of analyzing an INAP operation statistics command and transmitting a result according to an operator's request in an intelligent information providing system.

When the system is started and the process starts 30, it is placed in a waiting state 31 for receiving messages from the operator. Upon receiving the request for performing the statistics (32), the item for performing the statistical analysis is analyzed (33). As a result of the analysis, if it is not the INAP operation statistics (34), the statistical processing for the corresponding item is performed (35), and returned to the path A to wait for receiving a message from the operator (31). In the case of the service statistics request for each resource which is the INAP operation statistics (34), the statistical command input window is analyzed (36). As a result of the analysis, if the command is input in the statistical graphic window (37), the user data type is set as statistical data (UserDataType = STATISTICS_DATA) (38). Then, the statistical work management table is searched (39). If the command is not entered in the statistical graphic window, the process proceeds directly to step 39 of searching the statistical work management table. Next, it is checked whether the statistical work can be performed (40). At this time, if the number of INAP operation statistics work being performed reaches the limit set by the system and it is impossible to perform new statistics work, if the user data type is statistical data (UserDataType = STATISTICS_DATA) to send an error message to the operator (43) Formatting (44) a message for failure cause transmission to the graphical statistics window, transmitting an error message to the statistics window (45) about the inability to perform statistical work, and waiting to receive a new message from the operator (31). . On the other hand, if the user data type is not statistical data (UserDataType = STATISTICS_DATA) (43) after the message formatting for transmission of the cause of the failure to the message output window (46), and transmits an error message to the message output window about the inability to perform statistical operations (47), and proceeds to path A, waiting (31) to receive new messages.

On the other hand, if the statistical task can be performed (40), information about the task is registered 41 in the statistical task management table, the operator request inputs are analyzed 42, and the process proceeds to the path B. The INAP operation statistics perform measurement on all INAP operations transmitted and received by the intelligent peripheral device (IP) without having to specify a measurement target. Therefore, first of all, the user input checks whether the measurement start time is input (48), and if not input, the measurement start time is designated as the current time (49). If the operator has entered a measurement start time at step 48, the user at step 52 to verify 50 a measurement start time error, and if it is 51, send an error message for the measurement start time error to the operator. If the data type is statistical data (UserDataType = STATISTICS_DATA), format the message for transmitting the measurement start time error in the graphical statistics window (53). If the user data type is not statistical data (UserDataType = STATISTICS_DATA), the measurement start time is displayed in the message output window. After formatting the message for error transmission (54), the corresponding statistical information is deleted (55) from the statistical work management table, the measurement start time error message is transmitted (56), and then the path A is progressed.

On the other hand, if the measurement start time verification is successful (51) in step 51, the measurement start time is designated (57) by the time input by the operator, and the measurement start time is registered (58) in the timer, Receive 59 a measurement start time notification message from a timer. When the measurement start time is reached, the operator checks whether the measurement execution time has been entered (60) .If the measurement execution time has been entered, the measurement period is designated by the measurement execution time entered by the operator (61). The measurement period is designated by the determined measurement execution time (62). If the number of measurement repetitions is input (63), if the number of measurement repetitions is input, the number of measurement repetitions is designated by the data input by the operator (65), and if not, the number of measurement repetitions is designated as 1 (64). do. Then, the number of measurement executions is incremented by one (66) to collect measurement data, and the process proceeds to path C to register a timer 67 for receiving a measurement period expiration time notification with the timer. Then, the INAP operation related measurement information collected and stored in the MSLC library so far is read and stored in the initial data storage area (Init_Data) (68). The MSLC block then collects, accumulates and stores INAP operation statistics data from the service control block (steps 11-20 and 69). Upon receiving the measurement period expiration time from the timer (70), the INAP operation related measurement information stored in the MSLC library is read and stored in the final data storage area (Last_Data) (71), and the library is calculated to calculate the INAP operation statistics data. "Last_Data-Init_Data" is performed for each stored INAP operation (72). Next, the operator command input window is analyzed to transmit the calculated result to the operator. That is, in step 73, when the user data type is statistical data (UserDataType = STATISTICS_DATA), the graphic output message is formatted (74) in order to transmit the statistical result to the graphical statistical window (75) and the statistical result is transmitted to the graphical statistical window (75). . On the other hand, in step 73, if the user data type is not statistical data (UserDataType = STATISTICS_DATA), the text output message formatting 76 for transmitting the statistical result to the message output window is performed to transmit the statistical result to the message output window (77). . After the statistical result is transmitted in step 78, if the number of measurement repetitions input by the operator is 0, the processes of steps 66 to 77 are repeated indefinitely until the operator cancels the command for performing the INAP operation statistics (79). ). On the other hand, in step (78), if the number of measurement repetitions is not 0, the comparison is made (80) to determine whether the number of measurement repetitions is equal to the number of measurement repetitions. , The measurement is terminated. On the other hand, if the number of measurements performed and the number of measurement repetitions in step 80 is not the same, the process proceeds to path E. If the number of measurement performed in step (83) is less than the number of measurement repetitions, the process proceeds to the path D, and the number of measurement executions is increased by one until the number of measurement executions is equal to the number of measurement repetitions (66). Repeat the process. If the number of times of measurement is not less than the number of times of measurement, in order to transmit an error message about the number of times of measurement execution to the operator, if the user data type is statistical data (UserDataType = STATISTICS_DATA) in step 84, the number of statistics is performed in the graphical statistics window. Format an output message for error transmission to the processor 85 to transmit the error message to the graphical statistics window. If the user data type is not statistical data (UserDataType = STATISTICS_DATA) in step 84, a message 87 is sent to the message output window for sending an error about the number of statistics performed, and an error message is sent to the message output window ( 88). Subsequently, the statistical information is deleted from the statistical work management table (89), and then ends (90).

On the other hand, when a user receives a statistics cancel request from the operator (31) and waits (91), the user cancels the statistics cancel request item (92), searches the statistics work management table (93), and registers the statistics cancel request item ( 94) Check if it is running. At this time, if the corresponding statistics item is not registered, an error message about the failure to cancel the statistical work execution request is transmitted to the operator (99), and waiting (31) to receive a new message from the operator, and the corresponding statistical item is registered in the table. If it is (94), it requests (95) the termination of the process in which the statistics work is being performed, and terminates the process (96). After the corresponding statistical information is deleted from the statistical work management table (97), the statistical work execution cancellation success message is transmitted to the operator (98). Then wait 31 again to receive a new message from the operator.

Figure 5 shows the output content of the INAP operation statistics in the intelligent information providing system.

The INAP operation statistics are the number of operations received (RCV_CNT) and the number of operations sent (SND_CNT) for each operation such as user information collection (PCUI), message recording (PRM), announcement broadcast (PA), message deletion (EM), and operation cancellation (CANCEL). ), The number of successful operations performed (SUCCCNT), the number of unsuccessful attempts by the SCP for unavailable resources (UNAVAIL), the number of failures due to IP internal channel reasons, UNOBTAIN, the number of unsuccessful SRU system congestion (CONGEST), and the operation cancel (CANCEL) failed. Number of times (CANCFAIL), number of failures due to error in resource provision (RSCFAIL), number of operations canceled due to SCP request (SCPCANC), total operation processing time (TSVCTIME), average operation processing time (ASVCTIME) Information about) is displayed.

According to the present invention as described above, the data write part for collecting the INAP operation statistics data and storing it in the memory and the data read part for formatting the information required at the required time and delivering it to the operator, Load and service load can be minimized.In addition, the number of times of transmission and reception, the number of successful executions, the number of failure causes, and the operation processing time for each operation type received from SCP to provide resources in the intelligent peripheral device (IP). By outputting text and the like in the form of a graph desired by the operator, there is an effect of facilitating the results analysis by the operator.
