(Schematic configuration of the communication network monitoring device 3)
Next, a schematic configuration of the communication network monitoring device 3 will be described with reference to FIGS. FIG. 3 is a block diagram illustrating a schematic configuration of the communication NW monitoring device 3. In FIG. 3, for easy understanding, a communication network 100 connected to the communication NW monitoring device 3 and a monitoring terminal 500 used by an operator are shown together.
As shown in FIG. 3, the communication NW monitoring device 3 provided in the monitoring system 300 includes a distribution data storage unit 31, an NW configuration management unit 32, a customized data storage unit (an example of an arithmetic expression storage unit) 33, Calculation unit 34, calculation result storage unit 35, opposing adapter (hereinafter, the adapter may be abbreviated as “ADP”) 36, web adapter (hereinafter abbreviated as “WEB-ADP”) (calculation result output) Part) 37).

  The opposing ADP 36 acquires distribution data distributed through the communication network 100. The distribution data includes, for example, communication traffic data between NW components connected to each other among NW components 110 to 113-4 (not shown in FIG. 3) constituting the communication network 100, NW configuration It includes communication traffic data such as data traffic between the elements 113-1 to 113-4 and the mobile terminal devices 400-11 to 400-2 n 2 (not shown in FIG. 3), alarm data, or the like. The traffic data may be any data as long as the communication traffic can be quantitatively compared between the NW components, and may not be the communication traffic itself. For example, the traffic data may be the CPU usage rate of the NW component, the number of application transactions executed by the NW component, and the like.

  The distribution data storage unit 31 stores distribution data acquired by the opposing ADP 36 from the communication network 100. The distribution data storage unit 31 is configured to manage distribution data acquired from the communication network 100 using a database or the like by assigning codes according to the type of the distribution data. The distribution data management unit 31 manages data used for calculation analysis of the communication network 100 with codes.

FIG. 4 shows an example of a data management structure for managing distribution data in the distribution data storage unit 31. In the example shown in FIG. 4, for convenience of explanation, the management items of distribution data are represented by symbols such as “A”, “B”, “α1”, “β1”. Further, in the example shown in FIG. 4, for convenience of explanation, the number of data included in each item is as illustrated, but the number of these data is not limited to the number of this example.
As shown in FIG. 4, the data management structure of distribution data is classified into four items of “category”, “distribution data item name”, “distribution data name”, and “serial number”.

  “Category” indicates the type of the NW component, and is classified according to items such as a communication method for NW configuration and whether the NW component is a node system or an access system, for example. In this example, the category is classified into two items of “A” and “B” (for example, IMT (International Mobile Telecommunication) and wireless LTE (Long Term Evolution) radio).

  “Distribution data item name” indicates the type of distribution data and is classified in association with the category. In this example, the distribution data item names are “α1”, “α2”, “β1”, “β2”, and “β3” (for example, CS (Circuit Switched) or PS (Packet Switched) transmission completion rate, CS or PS (Α1) and “α2” are associated with the category “A”, and “β1”, “β2”, and “β3” correspond to the category “B”. It is attached.

  “Distribution data name” is the name of distribution data acquired from the communication network, and indicates specific distribution data included in the distribution data item name. Data classified and stored as “distributed data name” is a value that is substituted into an argument of a dedicated function included in an arithmetic expression described later. In this example, the distribution data names are “α1-1”, “α1-2”, “α2-1”, “α2-2”, “β1-1”, “β1-2”, “β2-1”. , “Β2-2” and “β3-1” (for example, the number of CS or PS transmission completions and the number of CS or PS call completions). The distribution data names “α1-1” and “α1-2” are included in the distribution data item name “α1”, and the distribution data names “α2-1” and “α2-2” are the distribution data item names. The distribution data names “β1-1” and “β1-2” are included in the distribution data item name “β1”, and the distribution data names “β2-1” and “β2-” are included in “α2”. 2 ”is included in the distribution data item name“ β2 ”, and the distribution data name“ β3-1 ”is included in the distribution data item name“ β3 ”.

  “Serial number” indicates a code assigned in association with “distributed data name”. Although the details will be described later, the number in the “serial number” is used as an argument of the dedicated function included in the arithmetic expression customized by the operator. The number in the serial number and the type of distribution data in the distribution data name are associated one-to-one, and a plurality of distribution data names are not assigned to one number in the serial number. For this reason, the corresponding distribution data is uniquely selected by designating one of the serial numbers. Thus, the communication NW monitoring device 3 can select distribution data necessary for calculation analysis of the communication network 100 by an operator specifying a serial number.

  Although illustration is omitted, the distribution data storage unit 31 holds information on the acquisition unit of distribution data in association with “category”. Further, the distribution data storage unit 31 associates with the “distribution data name” and stores information on distribution data collection period and collection type (whether it is an instantaneous value at a predetermined timing or a count value for a predetermined period). keeping. The distribution data storage unit 31 manages various distribution data acquired through the opposing ADP 36 as a database with the data management structure shown in FIG.

  Returning to FIG. 3, the NW configuration management unit 32 provided in the communication NW monitoring device 3 manages the network configuration information acquired by the opposite ADP 36 from the communication network 100. The NW configuration information is information related to the current connection between a plurality of NW components. The NW configuration information includes at least self information, information on higher NW components, and information on lower NW components. For example, the NW configuration information of the NW component 111-1 shown in FIG. 2 includes the self number as the information of the self (NW component 111-1) and the number of the NW component 110 as the information of the upper NW component. And the numbers of the NW components 112-1 and 112-2 are included as information of the lower NW components. The self number and the numbers of the upper and lower NW components are managed as ID numbers having a predetermined number of digits, for example, and by specifying the number of digits of the ID number (for example, specifying the lower four digits), The upper and lower NW components can be specified. The NW configuration management unit 32 manages NW configuration information of all NW components that constitute the communication network 100. For this reason, the NW configuration management unit 32 grasps the connection state between the NW components of the communication network 100 when the NW configuration information is acquired. Since the communication NW monitoring device 3 is configured to acquire NW configuration information at a predetermined cycle, for example, even if a change occurs in the NW configuration of the communication network 100, the latest NW configuration information related to the changed NW configuration is displayed. It can be managed by the NW configuration management unit 32. As a result, the communication NW monitoring device 3 can follow the change of the NW configuration.

  The customization data storage unit 33 stores an arithmetic expression customized by the operator. In the customized arithmetic expression, a logic component including a dedicated function having a code assigned according to the type of distribution data as an argument and data used for calculation analysis of network elements as a return value is used. The customized data storage unit 33 corresponds to an arithmetic expression storage unit. In the present embodiment, the arithmetic expression customized by the operator using the monitoring terminal 500 is input to the customized data storage unit 33 via the WEB-ADP 37.

  FIG. 5 is a diagram for explaining logic components used in the arithmetic expression. In the example shown in FIG. 5, for convenience of explanation, the dedicated function is written using abbreviated characters such as “◯◯◯ ()”. In the example shown in FIG. 5, for convenience of explanation, the number of dedicated functions is as shown in the figure, but the number of dedicated functions is not limited to the number of this example. In FIG. 5, “logic component” indicates a function that is provided in advance and can be used in the arithmetic expression, “description content” indicates the processing content in the arithmetic expression, and “use” is general purpose or not. Is shown. “General” in the application column represents a logic component for general use, and “Specific” represents a logic component for a specific application.

  In the present embodiment, “usable operators”, “usable language functions”, and “dedicated functions” are provided in advance as logic components. “Description contents” described as usable operators include addition, subtraction, multiplication, division, and the like. The processing contents of usable operators are calculations such as four arithmetic operations. Usable operators are general-purpose logic components, but the format of calculation formulas and operator priorities need to be created according to the rules of the language used. “Description contents” described in usable language functions include “total”, “arithmetic average”, and the like. The “summation” in the description content indicates a function that calculates a total value of a plurality of numerical values, and “arithmetic average” indicates a function that calculates an average value of a plurality of numerical values. The usable language functions are general-purpose parts, but the format of the calculation formula needs to be created according to the definition of the language to be used.

 The “description content” described in the “dedicated function” includes a function that uses data used for calculation analysis of the communication network such as the number of people in the NW component and the number of alarms as a return value. Dedicated functions are used for calculation analysis of communication networks and are special-purpose components that enable special operations. The dedicated function is composed of a part that suggests data used for calculation analysis of the communication network and a part that describes a code (in this example, a serial number) assigned according to the type of distribution data as an argument. For example, a description such as “BTS_Built-in” is used in the portion that suggests data to be used in the communication network, and it is suggested that the number of people in the base station can be obtained as return data. . In the portion describing the argument of the dedicated function, for example, the “serial number” number in the distribution data storage unit 31 is described. In this example, as shown in FIG. 4, dedicated functions “XX ()”, “XXX ()”, “ΔΔΔ ()”, and “□□□ ()” are provided in advance. Yes. Note that “xxx” in front of the parenthesis of each dedicated function is a part that suggests data to be used for the communication network, and the parenthesis part is a part that describes an argument.

  FIG. 6 is a diagram for explaining an arithmetic expression stored in the customization data storage unit 33. As shown in FIG. 6, there are five arithmetic expressions stored in the customization data storage unit 33: “category”, “target device”, “arithmetic expression number”, “corresponding terminal ratio condition number”, and “arithmetic expression”. Consists of items. “Category” corresponds to “Category” shown in FIG. 4 and indicates a category including a serial number (distributed data name) used as an argument of an arithmetic expression. “Target device” indicates an NW component to be calculated. “Operational expression” indicates an arithmetic expression customized by the operator. Details of the “arithmetic number” and “corresponding terminal ratio condition number” will be described later.

  Here, an arithmetic expression (first line excluding the item line in the drawing of FIG. 6) for obtaining the calculation result of XX of the NW component 112 and the calculation result of ΔΔΔ of the NW component 113 are obtained. Custom data storage, taking as an example an arithmetic expression (second line in the figure) and an arithmetic expression (third line in the figure) for obtaining the calculation result of XX of the NW component 111 The arithmetic expression stored in the unit 33 will be specifically described.

  For the calculation of XXX of the NW component 112, for example, it is necessary to add the exclusive function "XXX ()" and the distribution data names "α1-1" and "α1-2". . The operator operates the monitoring terminal 500 and selects “XX ()” of the dedicated function and serial numbers of “α1-1” and “α1-2” of the distribution data names, thereby The arithmetic expression “(α1-1_001 + α1-2_002)” is customized. The category including serial numbers “001” and “002” is “A”, and the target device is “NW component 112”. Also, assuming that the arithmetic expression number is “1” and the corresponding terminal ratio condition number is “0”, the arithmetic expression stored in the customized data storage unit 33 is “A, NW components 112, 1, 0, OO (α1-1_001 + α1-2_002) ”. The arithmetic expression is stored in the customized data storage unit 33 via the WEB-ADP 37 in the csv file format, for example.

  In addition, for the calculation of ΔΔΔ of the NW component 113, for example, the exclusive function “ΔΔΔ ()” and the distribution data with the distribution data names “β1-1” and “β2-1” are summed. Suppose it is necessary. The category including the serial number “101” corresponding to β1-1 and the serial number “111” corresponding to β2-1 is “B”, and the target device is “NW component 113”. Also, assuming that the arithmetic expression number is “1” and the corresponding terminal ratio condition number is “0”, the arithmetic expression stored in the customized data storage unit 33 is “B, NW components 113, 1, 0, ΔΔΔ (β1-1 — 101 + β2-1 — 111) ”.

  In addition, in the calculation analysis of the communication network 100, the calculation result of “◯◯◯ (α1-1_001 + α1-2_002)” of the customized calculation formula and the calculation result of “ΔΔΔ (β1-1_101 + β2-1_111)” of the customization calculation formula When an integrated value is required, the arithmetic expression is an operator that indicates the integration of “usable operators” provided as logic components (in this example, the operator is represented by “* ”), And customized by multiplying the dedicated functions as“ XX (α1-1 — 001 + α1-2 — 002) * ΔΔΔ (β1-1 — 101 + β2-1 — 111) ”.

  Further, as shown in the third line in FIG. 6, the arithmetic expression may be a nested form in which the dedicated function is described in the argument portion of the dedicated function. The dedicated function indirectly uses the argument of the dedicated function described in the argument part as an argument. For the calculation of XXX of the NW component 111, for example, the dedicated function “XXX ()”, the dedicated function “xxx ()”, the distribution data names “α1-1” and “α1” -2 "is required to be added. The operator operates the monitoring terminal 500 to display the dedicated functions “XXX ()” and “XXX ()” and the distribution data names “α1-1” and “α1-2”. By selecting, the arithmetic expression “XXX” (xxx (α1-1_001 + α1-2_002)) ”is customized. The category including serial numbers “001” and “002” is “A”, and the target device is “NW component 111”. Also, assuming that the arithmetic expression number is “1” and the corresponding terminal ratio condition number is “0”, the arithmetic expression stored in the customized data storage unit 33 is “A, NW components 111, 1, 0, OO (xxx (α1-1_001 + α1-2_002)) ”.

  As described above, in the present embodiment, a dedicated function is prepared in advance for items that require special calculation for the calculation analysis of the communication network 100, and a code associated with the distribution data necessary for the calculation is dedicated. By describing it in the argument part of the function, a desired calculation result can be obtained. The communication NW monitoring apparatus 3 according to the present embodiment excludes information that is changed every day, such as the NW configuration of the communication network, from the dedicated function, and the NW configuration information managed by the NW configuration management unit 32 for these pieces of information. It is comprised so that it may absorb. For this reason, the operator can easily customize the arithmetic expression using the dedicated function without being aware of the current NW configuration or NW configuration change.

  Returning to FIG. 3, the calculation unit 34 provided in the communication NW monitoring device 3 includes an arithmetic expression stored in the customization data storage unit 33, NW configuration information managed by the NW configuration management unit 32, and distribution data. The distribution data stored in the storage unit 31 is bundled, calculation data generation processing for generating calculation data obtained by converting the calculation expression into a mathematical expression, and data used for calculation analysis of the communication network 100 are calculated using the calculation data. And an arithmetic process including a data calculation process to be performed. The calculation unit 34 executes a calculation data generation process 34a for generating calculation data by executing the calculation data generation process, and a calculation unit 34 for calculating data by executing the data calculation process using the generated calculation data. have. The calculation data generation unit 34a acquires distribution data corresponding to an argument included in the arithmetic expression from the distribution data storage unit, and generates a mathematical expression in which the argument is replaced with the acquired distribution data. Here, the circulation data replaced with the argument is numerical data, and the mathematical expression is an expression in which the character part representing the argument is replaced with the numerical value. Based on the NW configuration information managed by the NW configuration management unit 32, the calculation data generation unit 34a calculates the calculation formulas for all NW components under the subordinate (directly below) the target device associated with the calculation formula. Calculation data converted into a mathematical expression is generated.

  For example, the dedicated function “XXX ()” is an expression for calculating the number of NW components, and “xxx ()” is an expression for selecting the lowest NW component, and NW The value of α1-1_001 of the component 112-1 is “1000”, the value of α1-2_002 is “2000”, the value of α1-1_001 of the NW component 112-2 is “3000”, and α1 It is assumed that the value of −2 — 002 is “4000”. The calculation data generation unit 34a recognizes that the calculation target component calculates the number of people in the NW component under the NW component 111 based on the calculation formula transmitted from the customization data storage unit 33. To do. Based on the NW configuration information acquired from the NW configuration management unit 32, the calculation data generation unit 34a confirms that the NW components 112-1 and 112-2 are connected to the bottom of the NW component 111-1. Ascertain and calculate operation data obtained by converting the operation expression into a mathematical expression for each of the NW components 112-1 and 112-2. The calculation data generation unit 34a generates calculation data obtained by converting “xxx (α1-1_001 + α1-2_002)” in the calculation formula into a formula for the NW component 112-1. The calculation data generation unit 34a acquires “1000” as the value of α1-1_001 and “2000” as the value of α1-2_002 of the NW component 112-1 from the distribution data storage unit 31 and maps them to the calculation expression. , Converted into mathematical expression “c (1000) + c (2000)” to generate operation data. Similarly, the calculation data generation unit 34a acquires “3000” as the value of α1-1_001 and “4000” as the value of α1-2_002 of the NW component 112-2 from the distribution data storage unit 31 and sets Mapping is performed and converted into the mathematical expression “c (3000) + c (4000)” to generate operation data. In this example, the format of the mathematical formula obtained by the conversion follows the rules of the R language. The calculation data generation unit 34a transmits a calculation execution request including calculation data “c (1000) + c (2000)” and “c (3000) + c (4000)” obtained by converting the calculation formula into a mathematical expression to the calculation unit 34b. . In addition, since the dedicated function “XX ()” is a function for calculating the number of people in the service area, the generation unit 34 a generates the calculation data by using the two formulas “c (1000) + c (2000)” and “c ( (3000) + c (4000) ”is added to the calculation execution request.

  For example, even if the information about the connection between NW components such as how many NW components are connected at the bottom of one NW component is not included in the customized calculation formula, Based on the NW configuration information managed by the NW configuration management unit 32, the generation unit 34a selects distribution data to be used for the arithmetic expression from a large amount of distribution data stored in the distribution data storage unit 31, and calculates the arithmetic expression and the distribution data. And the operation data obtained by converting the operation expression into a mathematical expression can be generated.

  The calculation unit 34b executes a data calculation process for calculating data used for calculation analysis of the communication network 100 based on the calculation execution request including the calculation data transmitted from the calculation data generation unit 34a, and calculates the calculated calculation result. The data is transmitted to the result storage unit 35.

The calculation result storage unit 35 is configured to transmit the temporarily stored calculation result to the WEB-ADP 37 in accordance with, for example, a predetermined timing or a WEB-ADP 37 transmission request.
The WEB-ADP 37 is a data transmission / reception unit that bidirectionally transmits and receives data between the monitoring terminal 500 and the communication NW monitoring device 3. The WEB-ADP 37 transmits an arithmetic expression received from the monitoring terminal 500 to the customized data storage unit 33 and transmits a calculation result received from the calculation result storage unit 35 to the monitoring terminal 500.

The communication NW monitoring device 3 acquires distribution data at different timings according to the type in a predetermined period. Further, the communication NW monitoring device 3 acquires NW configuration information of a plurality of NW components 110 to 113-4 constituting the communication network 100 from the communication network 100 via the opposing ADP 36 and manages them by the NW configuration management unit 32. . The arithmetic expression customized by the operator transmitted from the monitoring terminal 500 via the WEB-ADP 35 is stored in the customization data storage unit 33. The communication NW monitoring device 3 binds the arithmetic expression stored in the customized data storage unit 33, the NW configuration information managed by the NW configuration management unit 32, and the distribution data stored in the distribution data storage unit 31.

Run. The communication NW monitoring device 3 stores the calculation result calculated by the calculation unit 34 in the calculation result storage unit 35 and outputs the stored calculation result to the monitoring terminal 500 via the WEB-ADP 37 at a predetermined timing.

  As described above, the communication NW monitoring device 3 according to the present embodiment absorbs the configuration of the communication network using the NW configuration information and separates it from the customized arithmetic expression as a calculation tool. The communication NW monitoring device 3 does not need to change the arithmetic expression if there is no change in the calculation analysis target of the communication network regardless of the configuration of the communication network or the change in the communication network configuration. This eliminates the need to modify the calculation tool program. Thereby, since the communication NW monitoring device 3 is not stopped for the program modification, the change of the communication network configuration can be easily reflected without interruption in the calculation of data used for the calculation analysis of the communication network. In addition, the communication network can be monitored without stopping.

The traffic item names are 12 such as “number of in-site profiles / LAC”, “CS call completion rate”, “CS call completion rate”, “PS (Packet Switched) call completion rate”, “PS call completion rate”, etc. It is classified by type. For example, “the number of in-site profiles / LAC” is associated with the categories “IMT radio” and “node system”, and the seven types from “CS transmission completion rate” to “handover rate” are the categories “IMT” “EMB (Evolved Packet System Mobility Management) -DEREGISTERED” and “EMM-REGISTRED” are associated with the categories “LTE radio” and “node system”. (Mobile-Originalized) data completion rate "and" MT (Mobile-Terminated) access completion rate "are associated with the categories" LTE radio "and" access system ".

  “Traffic data name” is the name of the traffic data acquired from the NW components constituting the 3G network 600, and indicates specific traffic data included in each traffic data item name. The data classified and stored as “traffic data name” is a value that is substituted into the argument of the dedicated function included in the arithmetic expression. In this embodiment, the traffic data names are “LAC (key information)”, “attach profile number (line)”, “detach profile number (line)”, “CS call completion number”, “CS call completion number”, etc. Are classified into 22 types of data. Among the traffic data names, “attach profile” indicates the number of mobile terminal devices registered in the CS-GW as traffic data related to calculation of the number of BTS users, which will be described later, and “detach profile” The number of mobile terminal apparatuses whose registration status with the CS-GW has been deleted is shown. “Line” in the attach profile or detach profile indicates that the location registration processing is performed by CS (circuit switching), and “Combine” indicates that the location registration processing is performed in cooperation with CS and PS (packet switching). It shows that. “CS transmission completion number” indicates the number of CS transmission completions, “CS transmission retransmission completion number” indicates the number of CS transmission completions retransmitted, and “CS reception completion number” indicates the number of CS reception completions. “CS incoming retransmission completion number” indicates the number of completed CS incoming retransmissions. “PS transmission completion number” indicates the number of PS transmission completions, “PS transmission retransmission completion number” indicates the number of retransmitted PS transmissions, and “PS reception completion number” indicates the number of PS reception completions. “PS incoming retransmission completion number” indicates the number of completed PS incoming retransmissions. “Number of completed branch additions” indicates the number of completions of intra-base station handover (SHO: Soft HandOver) or inter-base station handover (DHO: Diversity HandOver). “Number of users with Radio Link ID = 1” indicates the number of mobile terminal devices with a Radio Link number (the number of radio links) of 1, and “Number of users with Radio Link ID = 2” is a number of users with a Radio Link ID of 2. The number of terminal devices is shown, and the “number of users with Radio Link ID = 3” indicates the number of mobile terminal devices with a Radio Link number of 3. Five types of data from the distribution data name “LAC (key information)” to “number of detached profiles (Combine)” are included in the “number of visited profiles / LAC” of the traffic item name. “CS transmission completion number” is included in “CS transmission completion rate” of traffic item name, and “CS reception completion number” and “CS reception retransmission completion number” are included in “CS reception completion rate” of traffic item name. ing. Similarly, various types of traffic data of “traffic data name” are included in one of the types of traffic data of “traffic data item name”.

  “Serial number” indicates a code assigned in association with “traffic data name”. The serial number is used as an argument of a dedicated function included in an arithmetic expression customized by the operator. The serial number “0001” is assigned to the “attach profile number (line)” of the traffic data name, the serial number “0002” is assigned to the “detach profile number (line)” of the traffic data name, and the serial number “0003” is The traffic data name “Attach profile number (Combine)” is assigned, and the serial number “0004” is assigned to the traffic data name “Detach profile number (Combine)”. Different numbers are assigned to other traffic data names as serial numbers. The serial number and the traffic data name are associated with each other on a one-to-one basis, and a plurality of traffic data names are not assigned to one serial number. For this reason, the corresponding traffic data is uniquely selected by designating one of the serial numbers. Thereby, the communication NW monitoring device 3 can select the traffic data necessary for the calculation analysis of the 3G network 600 by the operator specifying the serial number.

  The “collection cycle” indicates a cycle for collecting traffic data. “Collection type” indicates how to collect traffic data. “Acquisition unit” indicates an NW component from which traffic data is collected. The traffic data collection period, collection type, and acquisition unit differ depending on the type of traffic data. For example, the collection period of the traffic data names “attach profile number (line)”, “detach profile number (line)”, “attach profile number (combine)”, and “detach profile number (combine)” is 15 minutes each. Each collection type is an instantaneous value every 15 minutes, and each acquisition unit is CS-GW. For example, these traffic data are calculated values obtained by averaging the instantaneous values acquired every 15 minutes over one hour, and each calculated value is stored in association with a serial number. Further, for example, the collection period of the traffic data names “CS transmission completion number” and “CS transmission retransmission completion number” is 1 minute, the collection type is a count value for 1 minute, and the acquisition unit is BTS, sector and carrier. It has become. These traffic data are sum values obtained by summing count values for one minute for one hour, and the respective total values are stored in association with numbers having different serial numbers. The distribution data storage unit 31 includes “CS transmission completion number” and “CS transmission retransmission completion number” for each of the BTSs 62-1 to 62-4, the sectors 63-1 to 63-7, and the carriers 64-1 to 64-8. Manage traffic data. The communication NW monitoring device 3 obtains the data of the traffic data name included in the traffic data item name for all NW components of the acquisition unit (for example, if the acquisition unit is BTS / sector / carrier, the BTS 62-1 to 62- 4, sectors 63-1 to 63-7 and carriers 64-1 to 64-8). The communication NW monitoring device 3 assigns serial numbers of different numbers to all the traffic data acquired from the 3G network 600 and stores them in a database. Thereby, the communication NW monitoring device 3 can select the traffic data of the NW component necessary for the calculation analysis of the 3G network 600 by the operator specifying one of the serial numbers.

  Next, logic components in the present embodiment will be described with reference to FIG. FIG. 9 is a diagram for explaining logic components used in the arithmetic expression in this embodiment. In FIG. 9, “logic component” indicates a function that is provided in advance and can be used in an arithmetic expression, “description content” indicates processing contents in the arithmetic expression, and “use” is general-purpose or not. “General-purpose” indicates that it is a logic component for general-purpose use, “IMT” indicates that it is a logic component for specific use used for NW components of 3G wireless communication, and “LTE” Indicates a specific-use logic component used for an NW component of LTE wireless communication, and “common” is a specific-use logic component used for both IMT and LTE wireless communication. It shows that there is.

  In this embodiment, “usable operators”, “usable language functions”, and “dedicated functions” are provided in advance as logic components. The “description contents” described as usable operators include “addition (+)”, “subtraction (−)”, “multiplication (*)”, “division (/)”, “power calculation (^)”. ”,“ Consolidation division (% /%) ”, and“ remainder (%%) ”. The processing contents of usable operators are calculations such as four arithmetic operations. Usable operators are general-purpose logic components, but the format of calculation formulas and operator priorities need to be created according to the rules of the language used. The “description content” described in the “usable language function” includes “sum”, “arithmetic mean”, and “concatenation (c)”. Summation (sum) indicates a function that calculates the total value of a plurality of numerical values, arithmetic mean (mean) indicates a function that calculates the average value of a plurality of numerical values, and concatenation (c) is in the array It is a function that concatenates the character strings (or numeric values) of and returns them as a character string. Usable language functions are general-purpose logic components, but the format of the calculation formula needs to be created according to the rules of the language used.

The “description content” described in the “dedicated function” includes a function having a return value as data used for calculation analysis of the NW component such as the number of people in the NW component and the number of alarms. Dedicated functions are used for calculation analysis of communication networks and are special-purpose components that enable special operations. The dedicated function is composed of a part that suggests data used for calculation analysis of the communication network and a part that describes a code (in this example, a serial number) assigned according to the type of distribution data as an argument. For example, a description such as “BTS_Built-in” is used in the portion that suggests data to be used in the communication network, and it is suggested that the number of people in the base station can be obtained as return data. . In the part describing the argument of the dedicated function, for example, the serial number assigned to the distribution data name in the distribution data storage unit 31 is described.
As shown in FIG. 9, in the communication NW management device 3 according to the present embodiment, “LAC unit_number of profiles ()” and “LAC unit_RNC collection traffic ()” used for calculation analysis regarding LAC, calculation analysis regarding BTS In total, 27 dedicated functions such as “different BTS_branch addition ()”, “BTS_branch addition ()”, “BTS_handover rate ()”, and “BTS_location ()” used in the above are provided.

  “LAC unit_number of profiles ()” is used to add up the number of profiles in LAC units, and “0001-0004” of “serial number” shown in FIG. 8 is used as an argument described in parentheses. Also, “BTS_Busy ()” is used to add up the number of carriers in BTS units, and “0001-0004”, “Between serial numbers” shown in FIG. 8 are used as arguments described in parentheses. 1001, 1002, 1011, 1012, 1021, 1022, 1031, 1041 "are used. Although detailed explanation is omitted, other dedicated functions are used for the calculation of the contents described in the remarks column of FIG.

  FIG. 10 is a diagram for explaining an arithmetic expression stored in the customization data storage unit 33. As shown in FIG. 10A, the arithmetic expressions stored in the customized data storage unit 33 are “category”, “target device”, “arithmetic expression number”, “corresponding terminal ratio condition number”, and “arithmetic expression”. It consists of five items. “Category” indicates a category including a serial number (distribution data name) used as an argument of an arithmetic expression, “target device” indicates an NW component to be calculated, and “calculation expression” is an arithmetic expression customized by an operator. Is shown. The “arithmetic expression number” is a number indicating whether or not the area coefficient is taken into consideration in the calculation, and is “1” when considered or “2” when not considered. The “corresponding terminal ratio condition number” indicates a number assigned according to the terminal ratio of the mobile terminal apparatus that supports a plurality of carriers. The corresponding terminal ratio condition number is “0” when the corresponding terminal ratio is 0%, “1.00” when 100%, “2” when 60%, and “3” when 40%. .

  Here, the corresponding terminal ratio and the area coefficient will be described. The number of users calculated by the communication NW monitoring device 3 is the number of users affected by interruption (the number of users who cannot use the service). When one area is covered with multiple carriers (2 GHz, 1.7 GHz, 1.5 GHz, 800 MHz) (when overlaying), a mobile terminal device that supports multiple carriers is in use. Even if one carrier breaks down, it is only necessary to use another carrier, so a single carrier failure does not interrupt service. On the other hand, since a mobile terminal apparatus that cannot handle a plurality of carriers cannot use another carrier when one carrier in use fails, it needs to be treated as a service interruption. Therefore, in this embodiment, the ratio of mobile terminal devices that support a plurality of carriers to all mobile terminal devices included in one LAC is defined as a corresponding terminal ratio, and the mobile terminal device is present at the time of service interruption. It is supposed to be excluded from the number of players. If the corresponding terminal ratio is 100%, the service can be continued on another carrier at the time of a single carrier failure, so the number of people in service (number of affected users) is treated as zero.

  The terminal ratio at which the mobile terminal apparatus is relieved by overlay (multiple carriers) even if a single carrier fails can be handled by a calculation formula by using the corresponding terminal ratio. However, in addition, there is a pattern that can be relieved between radio base stations as an area regardless of the overlay at the boundary of the serving cell between the radio base stations. A pattern that can be relieved between the radio base stations is defined in the form of an area coefficient. Details of the area coefficient calculation formula will be described later.

“Calculation formula” indicates a calculation formula customized by the operator. FIG. 10B shows in detail the expression described in the column of “arithmetic expression” surrounded by a broken line shown in FIG. As shown in FIG. 10A, “BTS” of the target device, “1” of the arithmetic expression number, and “2” of the corresponding terminal ratio condition number are associated with the arithmetic expression. For this reason, the calculation formula is a formula for calculating the number of BTS users in consideration of the area coefficient and the corresponding terminal ratio. The number of BTS users when the area coefficient and the corresponding terminal ratio are not taken into consideration is obtained by multiplying the number of people in the LAC unit by the number of CS / PS transmission / reception completions in the carrier (band) unit and CS / PS in the LAC unit It can be obtained by dividing by the number of outgoing / incoming calls completed. For this reason, as shown in FIG. 10 (b), the calculation formula includes the dedicated function “LAC” in the parentheses of the dedicated function “BTS_Built-in ()” whose return value is the number of BTS users. “Unit_profile number ()”, “carrier unit ()”, and “LAC unit_RNC collection traffic ()” are described, and serial numbers used for these dedicated functions are indirectly used as arguments. In addition, since the “corresponding terminal ratio condition number” is “2”, the term (1−0.60) is added to “BTS_location”. As a result, the term of the BTS area in the equation becomes “BTS_area (LAC unit_profile number (traffic_0001 + traffic_0002 + traffic_0003 + traffic_0004) * carrier unit (traffic_1001 + traffic_1011 + traffic_1021 + traffic_1031 + traffic_1002 + traffic). _1012 + traffic_1022 + traffic_1032) / LAC unit_RNC collection traffic (traffic_1001 + traffic_1011 + traffic_1021 + traffic_1031 + traffic_1002 + traffic_1012 + traffic_1022 + traffic_1032) * (1-1.00)) ”.
Further, the area coefficient is taken into consideration, and the area coefficient is added to the value calculated by the dedicated function “BTS_location ()”. The area coefficient can be obtained by the following equation (1). Note that the BTS indicates the BTS of the target device, and the branch addition completion number for the different BTS indicates the number of areas relieved by the BTS arranged next to the BTS.

Area coefficient = (1-x) ^ (y-1) (1)
x = (Number of completed branch additions from the BTS to the different BTS)
÷ (Number of completed branch additions in the BTS)
y = ((Radio Link ID 1 number of users × 1)
+ (Radio Link ID 2 number of users x 2)
+ (Radio Link ID 3 number of users x 3))
÷ ((Radio Link ID 1 number of users)
+ (Number of Radio Link ID 2 users)
+ (Radio Link ID 3 number of users))

  X in Expression (1) can be obtained by using “different BTS_branch addition ()” of the dedicated function and “BTS_branch addition ()” of the dedicated function, and y in Expression (1) is “ The BTS handover rate () ”can be used. Therefore, the area coefficient term in the arithmetic expression shown in FIG. 10B is “area coefficient ((1−different BTS_branch addition (traffic_1041 + traffic_1042) / (different BTS_branch addition (traffic_1041 + traffic_1042)) + BTS_ Branch addition (traffic_1041 + traffic_1042))) ^ (BTS_handover rate (traffic_1051 * 1 + traffic_1052 * 2 + traffic_1053 * 3) / BTS_handover rate (traffic 1051 + traffic 1052 + traffic 1053) -1)).

  Although the operator needs to customize the calculation formula using the monitoring terminal 500, the calculation formula does not include any information regarding the NW configuration of the 3G network 600. For this reason, even if there is a change in the NW configuration, the arithmetic expression is not changed. Thereby, the operator can customize the calculation formula without being aware of the current NW configuration or the changed NW configuration.

(Communication network monitoring method according to this embodiment)
Next, a method for monitoring a communication network according to the present embodiment will be described with reference to FIGS. 11 to 13 with reference to FIGS. 3 and 7 to 10. In this embodiment, a method for monitoring a communication network will be described by taking the calculation of the number of BTS users as an example. FIG. 11 is a flowchart illustrating an example of the flow of the communication network monitoring method according to the present embodiment. FIG. 12 is a flowchart illustrating an example of a flow of calculation data generation processing in the communication network monitoring method according to the present embodiment.

  The communication NW monitoring device 3 according to the present embodiment acquires traffic data and NW configuration information from the 3G network 600 at a predetermined cycle (for example, one hour cycle), and an arithmetic expression stored in the customized data storage unit 33 at the cycle. Based on the above, a predetermined calculation related to the target device is executed. For example, the communication NW monitoring device 3 according to the present embodiment starts the execution scenario of the BTS resident calculation after acquiring all data such as traffic data.

  In the communication network monitoring method according to the present embodiment, when the information acquisition start timing is reached, all the NW components (IP-RNCs 61-1 to 61-3, BTS 62-1 to 62-4, sector 63, which constitute the 3G network 600). -1 to 63-7 and carriers 64-1 to 64-8), distribution data (traffic data in this embodiment) is started, and acquisition of NW configuration information is started (step S1). The acquired traffic data is stored as a database in the distribution data storage unit 31, and the NW configuration information is transmitted to the NW configuration management unit 32 and managed.

In step S2 subsequent to step S1, an arithmetic expression customized by the operator is acquired and stored in the customized data storage unit 33. For example, the customization data storage unit 33 acquires an arithmetic expression associated with the target device or the like via the WEB-ADP 37, stores it as a database, and stores it. Note that the arithmetic expression acquired and stored by the customized data storage unit 33 is not limited to one and may be plural.
In step S3 subsequent to step S2, a user calculation execution scenario is activated to execute calculation data generation processing. The calculation data generation process is executed by the calculation data generation unit 34a. The in-service person calculation execution scenario is activated after the acquisition of all data of traffic data and NW configuration information is completed.

As shown in FIG. 12, in the calculation data generation process, first, all traffic data related to the target device to be calculated is acquired from the distribution data storage unit 31 (step S101). For example, the calculation data generation unit 34a of the calculation unit 34 includes the traffic data of the BTS 62-1 to 62-4 and all the NW components (in this example, connected directly or indirectly to the BTS 62-1 to 62-4). The traffic data of the sectors 63-1 to 63-7, the carriers 64-1 to 63-8, and the IP-RNCs 61-1 to 61-3) are acquired, and the process proceeds to step S102.
In step S102 following step S101, an arithmetic expression is acquired from the customization data storage unit 33. For example, the calculation data generation unit 34a acquires the calculation formula and information such as the target device and the calculation formula number associated with the calculation formula from the customization data storage unit 33, and proceeds to step S103.

  In step S103 following step S102, NW configuration information of the NW component related to the calculation target is acquired from the NW configuration management unit 32. In order to calculate the NW component to be calculated, NW configuration information of all NW components connected to the NW component such as the lowest device is required. Therefore, the calculation data generation unit 34a acquires the NW configuration information of the BTSs 62-1 to 62-4 that are the calculation targets, and is connected to the BTSs 62-1 to 62-4 based on the acquired NW configuration information. The NW configuration information of the NW component is acquired. For example, the NW configuration information of the BTSs 62-1 to 62-4 includes information that the upper NW components are IP-RNCs 61-1 to 61-3, and the lowest NW component is the sector 63-. Information of 1 to 63-7 is included. For this reason, for example, for the BTS 62-1, the calculation data generation unit 34a acquires the NW configuration information of the IP-RNC 61-1 and the sectors 63-1 and 63-2. Similarly, the operation data generation unit 34a acquires the NW configuration information of the IP-RNCs 61-2 and 61-3 and the sectors 63-3 to 63-7 for the BTSs 62-2 to 62-4. Furthermore, the calculation data generation unit 34a acquires the NW configuration information of the carriers 64-1 to 64-8 based on the acquired NW configuration information of the sector. When the acquisition of all NW configuration information is completed, the calculation data generation unit 34a proceeds to step S104.

  In step S104 subsequent to step S103, an arithmetic expression decomposition process is executed. The calculation data generation unit 34a decomposes the calculation formula acquired from the customization data storage unit 33 for each dedicated function included in the calculation formula. The dedicated function is decomposed into a part that suggests data used for calculation analysis of the communication network and an argument part. FIG. 13 is a conceptual diagram of an arithmetic expression that has been subjected to decomposition processing, and shows a state in which the arithmetic expression shown in FIG.

  As illustrated in FIG. 13, the calculation data generation unit 34 a includes “LAC unit_number of profiles ()”, “carrier unit ()”, “LAC unit_RNC collection traffic ()” of eight dedicated functions included in the calculation formula. ”,“ Add another BTS_branch () ”,“ Add another BTS_branch () ”,“ Add BTS_branch () ”,“ BTS_handover rate () ”and“ BTS_handover rate () ”, respectively, The process is divided into a part suggesting data used for calculation analysis of the 3G network 600 shown on the left side and an argument part shown on the right side, and the process proceeds to step S105. The calculation data generation unit 34a also extracts the corresponding terminal ratio portion from the calculation formula. The calculation target NW component and all NW components that are directly or indirectly connected to the calculation target NW component such as the subordinate apparatus of the NW component are decomposed.

  In step S105 following step S104, calculation data and a calculation file are generated. In step S <b> 105, the arithmetic data generation unit 34 a first generates arithmetic data in which the arithmetic expression is converted into an equation by replacing the argument of the decomposed arithmetic expression with the value of the acquired traffic data. For example, it is assumed that the acquired traffic data values corresponding to traffic_0001, 0002, 0003, and 0004 are 1000, 2000, 3000, and 4000, respectively. In this case, the calculation data generation unit 34a sets “trac_0001 + traffic_0002 + traffic_0003 + traffic_0004” in the argument portion of the LAC unit_profile number shown in the uppermost part of FIG. 13 to “c (1000) + c (2000) + c ( 3000) + c (4000) ", and the operation data converted into the mathematical expression is generated by replacing the acquired value. The calculation data generation unit 34a generates calculation data for each carrier accommodated in each of the BTSs 62-1 to 62-4. For example, the BTS 62-1 accommodates the carriers 64-1 to 64-3, and the LAC1 is configured as a domain by the carriers 64-1 to 64-3. For this reason, for the BTS 62-1, the traffic data acquired in the LAC1 and the operation data in which the arguments are replaced with the values of the traffic data acquired in the carrier 64-1, and the traffic data acquired in the LAC1 The calculation data obtained by replacing the argument with the value, the value of the traffic data acquired in the carrier 64-2, the value of the traffic data acquired in the LAC1, and the value of the traffic data acquired in the carrier 64-3 Calculation data with the arguments replaced is generated. Similarly, the calculation data generation unit 34a generates calculation data for the BTSs 62-2 to 62-4.

After the calculation data is generated, the calculation data generation unit 34a generates a calculation file expressed in a predetermined file format for each generated calculation data, and the process proceeds to step S106.
In step S106 following step S105, a calculation execution request including the generated calculation file is transmitted to the calculation unit 34b. In addition to the calculation file, the calculation execution request includes calculation formulas and calculation processing information indicating how to process the values calculated by substituting the formulas described in the calculation file into the calculation formulas. The purpose of this embodiment is to calculate the number of BTS users. The number of people in the BTS can be obtained by adding the number of people in the lower NW component. For this reason, the calculation processing information includes an addition instruction for adding the values calculated using the three calculation files generated from the three calculation data related to the BTS 62-1. Further, the calculation processing information includes the same addition instruction regarding the BTSs 62-2 to 62-4. When the calculation data generation unit 43a transmits a calculation execution request to the calculation unit 34b, the calculation data generation process ends.

  Returning to FIG. 10, in step S4 following the calculation data generation process (step S3), the calculation is executed based on the acquired calculation expression and the calculation file including the generated calculation data. For example, the calculation unit 34b executes a data calculation process for calculating data used for calculation analysis of the NW component of the 3G network 600 based on the calculation formula, the calculation file, and the calculation process information included in the calculation execution request. The calculation result is transmitted to the calculation result storage unit 35. The calculation unit 34b performs the process specified by the calculation process information after calculating each using the calculation file. The calculation unit 34b executes such calculation processing for each NW component to be calculated (in this example, for each BTS 64-1 to 64-4).

In step S5 following step S4, the calculation result transmitted from the calculation unit 34b is stored. For example, the calculation result storage unit 35 temporarily stores the calculation result transmitted from the calculation unit 34b.
In step S6 subsequent to step S5, the calculation result stored in the calculation result storage unit 35 is output. For example, the WEB-ADP 37 outputs the calculation result transmitted from the calculation result storage unit 35 to the monitoring terminal 500. Thus, the communication network monitoring method ends.
The communication NW monitoring device 3 according to the present embodiment repeatedly executes the processing from step S1 to step S6 shown in FIG. 10 at a predetermined cycle, and monitors the communication network. The operator can perform calculation analysis of the 3G network 600 by using, for example, the calculation result output to the monitoring terminal 500, such as discovery or prediction of a congested NW component.

  As described above, the communication NW monitoring apparatus 3 according to the present embodiment absorbs the configuration of the communication network using the NW configuration information and separates it from the customized arithmetic expression as a calculation tool. The communication NW monitoring device 3 does not need to change the arithmetic expression if there is no change in the calculation analysis target of the communication network regardless of the configuration of the communication network or the change in the communication network configuration. This eliminates the need to modify the calculation tool program. Thereby, since the communication NW monitoring device 3 is not stopped for the program modification, the communication network can be monitored in a non-stop state.

(Communication NW monitoring method when communication network configuration changes)
Next, a method for monitoring a communication network when a change occurs in the configuration of the communication network will be described with reference to FIGS. 14, 15, and 11 with reference to FIGS.
First, a case will be described as an example where a BTS is added and the NW configuration of the 3G network 600 is changed. FIG. 14 shows the 3G network 600, in which only the BTS 62-2, the sectors 63-3 and 63-4, the carriers 64-4 and 64-5, and the added BTS 62-5 are extracted.

  In this example, since the NW configuration of the 3G network 600 is in the state shown in FIG. 7 at the start of the processing in step S1 shown in FIG. 10, the communication NW monitoring device 3 has the NW configuration information in the connection state shown in FIG. And managed by the NW configuration management unit 32. In the calculation data generation process (step S3) executed thereafter, the NW configuration information in the connection state shown in FIG. 7 managed by the NW configuration management unit 32 is used. As shown in FIG. 14 after the calculation data generation processing is started, when the BTS 62-5 is added, the NW configuration information of the NW component affected by the addition of the BTS 62-5 is updated. In this example, the NW configuration information of the lower sector 63-4 of the BTS 62-5 is updated. The NW configuration information of the sector 63-4 before the addition of the BTS 62-5 includes the BTS 62-2 as the NW component number immediately above, but the NW configuration of the sector 63-4 after the addition of the BTS 62-5 The information includes the BTS 62-5 number in addition to the BTS 62-2.

  Even if the NW configuration information managed by the NW configuration management unit 32 is changed during the calculation process, the calculation unit 34 does not reflect the change of the NW configuration information in the calculation process being executed until the calculation process is completed. It is like that. Therefore, as shown in FIG. 14, the BTS 62-5 is added during the arithmetic processing, the NW configuration information of the sector 63-4 managed by the NW configuration management unit 32 is changed, and the NW configuration information of the BTS 62-5 is changed. Even if is added, the calculation unit 34 does not reflect the change / addition of the NW configuration information in the calculation process being executed, and continues the calculation process being executed. The calculation unit 34 reflects the change / addition of the NW configuration information in the calculation process to be started next after the calculation being processed.

  When the network configuration is changed, the conventional communication NW monitoring system must be stopped for the program modification of the calculation tool. On the other hand, the communication NW monitoring device 3 absorbs the change of the network configuration by using the NW configuration information and separates it from the customized arithmetic expression as a calculation tool. Even if the network configuration changes, the communication NW monitoring device 3 does not need to change the calculation formula if there is no change in the calculation target of the communication network. Thereby, since the communication NW monitoring device 3 is not stopped for the program modification, the communication network can be monitored in a non-stop state.

  Next, a case where a carrier is added and the NW configuration of the 3G network 600 is changed will be described as an example. FIG. 15 shows the 3G network 600, in which only the BTS 62-2, the sectors 63-3 and 63-4, the carriers 64-4 and 64-5, and the added carrier 64-9 are extracted.

  In the same manner as described with reference to FIG. 14, when the calculation data generation process is started in the calculation data generation unit 34 a and the carrier 64-9 is added as illustrated in FIG. 15, the addition of the carrier 64-9 is performed. The NW configuration information of the affected NW component is updated. In this example, since the carrier 64-9 is the lowest NW component of the sector 63-4, the NW configuration information of the sector 63-4 is updated. The NW configuration information of the sector 63-4 before the addition of the carrier 64-9 includes the number of the carrier 64-5 as the lowest NW component, but the sector 63- after the addition of the carrier 64-9 The NW configuration information of 4 includes the number of the carrier 64-9 in addition to the number of the carrier 64-5.

  As described with reference to FIG. 14, the communication NW monitoring device 3 does not need to change the arithmetic expression associated with the change of the communication network configuration due to the addition of the carrier 64-5, and the calculation processing is being executed. Is not reflected, but is reflected from the next calculation processing to be started, so that it is possible to continue monitoring the communication network without stopping.

  14 and 15, the case where the configuration of the communication network is changed has been described. However, the calculation unit 34 included in the communication NW monitoring device 3 can perform the calculation stored in the customized data storage unit 33 during the calculation process. Even if the formula is changed, the change of the calculation formula is not reflected on the calculation processing being executed until the calculation processing is completed. In this embodiment, since the operator can easily customize the arithmetic expression using a dedicated function, it is possible to change the arithmetic expression in a short time compared with the program modification of the calculation tool of the conventional communication NW monitoring system. is there. As a result, the communication NW monitoring device 3 changes the arithmetic expression in a short time, and even if the arithmetic expression is changed, the communication NW monitoring apparatus 3 does not reflect the change in the ongoing arithmetic processing, but reflects it from the arithmetic processing to be started next. Therefore, it is possible to continue monitoring the communication network without stopping.

In the present embodiment, the logic component is provided in advance in the communication NW monitoring device 3 (for example, the customization data storage unit 33), and when the operator customizes the arithmetic expression, the logic component is provided in the monitoring terminal 500 via the WEB-ADP 37. It may be downloaded. In this case, the monitoring terminal 500 is not included in the monitoring system 300.
On the other hand, in the present embodiment, the logic component may be provided in advance in an external device (for example, the monitoring terminal 500) other than the communication NW monitoring device 3. In this case, the monitoring system 300 includes the external device. Therefore, for example, when a logic component is provided in the monitoring terminal 500 in advance, the monitoring system 300 includes at least the communication NW monitoring device 3 and the monitoring terminal 500.

  The present invention can be embodied as a computer program. For example, the function of each unit of the communication NW monitoring device 3 can be realized as a communication program. Thus, some or all of the present invention can be incorporated into hardware or software (including firmware, resident software, microcode, state machines, gate arrays, etc.). Furthermore, the present invention may take the form of a computer program product on a computer-usable or computer-readable storage medium, which incorporates computer-usable or computer-readable program code. It is done. In the context of this specification, a computer usable or computer readable medium includes, stores, communicates, propagates, programs that are used by or in conjunction with an instruction execution system, apparatus or device, Alternatively, any medium that can be transported can be used.

The present invention is not limited to the above embodiment, and various modifications can be made.
In the above embodiment, the serial number is used as the sign of the argument of the dedicated function, but the present invention is not limited to this. For example, if circulation data corresponding to designating one code is uniquely selected, a character other than a number or a character string combining a number and a character can be used as the code. .

  In the above embodiment, the traffic data is taken as an example of the distribution data, but the present invention is not limited to this. For example, as an example of the distribution data acquired from the communication network, there is alarm data raised from the communication NW component due to a failure, for example. The alarm data can be used for alarm aggregation and alarm trend analysis in the monitored communication network. In the alarm totalization, the number of communication NW components can be accumulated, or the number of alarms per week in the communication network to be monitored can be calculated. Further, when an alarm is raised in one communication NW component, the alarm may be associated with the other communication NW component connected to the one communication NW component. By analyzing the tendency of such alarms, the number of related alarms and alarm contents in the monitored communication network can be tabulated.

  The scope of the present invention is not limited to the illustrated and described exemplary embodiments, but includes all embodiments that provide the same effects as those intended by the present invention. Furthermore, the scope of the invention is not limited to the combinations of features of the invention defined by the claims, but can be defined by any desired combination of particular features among all the disclosed features.
