[0011] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In this disclosure, the drawings may relate to one or more embodiments. Furthermore, each element in the drawings may apply to one or more embodiments. In each drawing, the same or corresponding elements are designated by the same reference numerals, and duplicated explanations will be omitted as necessary for clarity of explanation.

[0012] First Embodiment <Example of control device configuration> Fig. 1 is a block diagram showing an example of a control device of the present disclosure. In Fig. 1, the control device 10 has an acquisition unit 11 and a comprehensive evaluation value calculation unit (first calculation unit) 12. For example, the control device 10 may be disposed in a core network device, a network device such as a base station, or a terminal device.

[0013] The acquisition unit 11 acquires a measurement value set. The measurement value set includes a plurality of measurement values ​​corresponding to a plurality of items related to the quality of an evaluation target. The evaluation target may be, for example, a network slice. The plurality of items may be two or more of bandwidth (throughput), delay, congestion, packet loss, line disconnection, and jitter.

[0014] The overall evaluation value calculation unit 12 calculates an overall evaluation value, which is an overall evaluation index for the measurement value set, based on the multiple measurement values ​​in the measurement value set acquired by the acquisition unit 11. For example, the overall evaluation value calculation unit 12 may calculate the sum of the multiple measurement values ​​in the measurement value set as the overall evaluation value.

[0015] <Example of control device operation> FIG. 2 is a flowchart showing an example of the processing operation of the control device of the present disclosure.

[0016] The acquisition unit 11 acquires a measurement value set (step S11).

[0017] The overall evaluation value calculation unit 12 calculates an overall evaluation value, which is an overall evaluation index for the measurement value set, based on the multiple measurement values ​​in the acquired measurement value set (step S12).

[0018] As described above, according to the first embodiment, the overall evaluation value calculation unit 12 in the control device 10 calculates an overall evaluation value, which is an overall evaluation index of the measurement value set, based on multiple measurement values ​​of the measurement value set acquired by the acquisition unit 11.

[0019] The configuration of the control device 10 makes it possible to calculate a comprehensive evaluation value, which is a comprehensive evaluation index for the evaluation target. By using this comprehensive evaluation value for evaluation, it is possible to improve the accuracy of the evaluation.

[0020] Second Embodiment <Example of control device configuration> 3 is a block diagram showing another example of a control device according to the present disclosure. In FIG. 3, a control device 20 includes an acquisition unit 21 and a comprehensive evaluation value calculation unit (first calculation unit) 22.

[0021] The acquiring unit 21 acquires a measurement value set in the same manner as the acquiring unit 11. However, the number of items corresponding to the measurement values ​​included in the measurement value set is three or more.

[0022] Similar to the overall evaluation value calculation unit 12, the overall evaluation value calculation unit 22 calculates an overall evaluation value, which is an overall evaluation index for the measurement value set, based on the multiple measurement values ​​of the measurement value set acquired by the acquisition unit 21.

[0023] For example, the comprehensive evaluation value calculation unit 22 includes a radar chart creation unit 22A and an area calculation unit 22B.

[0024] The radar chart creation unit 22A plots a plurality of values ​​corresponding to the plurality of measurement values ​​of the measurement value set on a radar chart having a plurality of axes corresponding to the plurality of items, respectively. For example, as shown in FIG. 4, each axis of the radar chart has a plurality of plot candidate points (e.g., scale 1, scale 2, scale 3, scale 4, and scale 5). The radar chart creation unit 22A may plot the measurement value for each item at a plot candidate point corresponding to the measurement value range that includes the measurement value for each item, based on the correspondence between the plurality of measurement value ranges for each item and the plot point candidates corresponding to each measurement value range. FIG. 4 is a diagram showing an example of a radar chart.

[0025] The area calculation unit 22B calculates the area of ​​a figure formed by connecting two adjacent points among the multiple points plotted on the radar chart as the overall evaluation value. For example, the shape of a triangle formed between the two adjacent axes and the area of ​​the triangle are uniquely determined by the scale values ​​of the two points plotted on the two adjacent axes. Therefore, the area calculation unit 22B may store a correspondence relationship between all combinations of the scale values ​​of the two points plotted on the two adjacent axes and the area of ​​the triangle corresponding to each combination. Then, the area calculation unit 22B may use this correspondence relationship to identify the area of ​​the triangle formed between each of the two axes of the radar chart. Then, the area calculation unit 22B may calculate the overall evaluation value by calculating the sum of the areas of all the identified triangles.

[0026] Here, when the number of items corresponding to the measured values ​​included in the measurement value set is four or more, the order of the items may be predetermined according to the following correlation: That is, the correlation between a first item among the multiple items and a second item corresponding to a second axis adjacent to the first axis corresponding to the first item in the radar chart may be higher than the correlation between the first item and a third item corresponding to a third axis not adjacent to the first axis. This makes it possible to increase the weight (contribution) of the two highly correlated items in the overall evaluation value calculated by area calculation unit 22B.

[0027] <Example of control device operation> FIG. 5 is a flowchart showing another example of the processing operation of the control device of the present disclosure.

[0028] The acquisition unit 21 acquires a measurement value set (step S21).

[0029] The radar chart creation unit 22A plots a plurality of values ​​corresponding to the plurality of measurement values ​​of the measurement value set on a radar chart having a plurality of axes corresponding to the plurality of items respectively (step S22).

[0030] The area calculation unit 22B calculates the area of ​​a figure formed by connecting each two adjacent points among the plurality of points plotted on the radar chart as a comprehensive evaluation value (step S23).

[0031] As described above, according to the second embodiment, the radar chart creation unit 22A in the control device 10 plots a plurality of values ​​corresponding to the plurality of measurement values ​​in the measurement value set on a radar chart having a plurality of axes corresponding to the plurality of items, respectively. The area calculation unit 22B calculates the area of ​​a figure formed by connecting each two adjacent points among the plurality of points plotted on the radar chart as the overall evaluation value.

[0032] The configuration of the control device 20 makes it possible to calculate a comprehensive evaluation value, which is a comprehensive evaluation index of the evaluation target, as the area of ​​the radar chart. By using this comprehensive evaluation value for evaluation, it is possible to improve the evaluation accuracy.

[0033] <Modification of the second embodiment> The radar chart creation unit 22A may plot multiple values ​​corresponding to the multiple measurement values ​​of the measurement value set on multiple radar charts, each having multiple axes corresponding to multiple items and arranged in a different order from one another.The area calculation unit 22B may then calculate the area of ​​a figure formed by connecting two adjacent points among the multiple points plotted on each of the multiple radar charts.The area calculation unit 22B may then calculate the sum or average of the multiple areas calculated for the multiple radar charts as the overall evaluation value.This makes it possible to calculate an overall evaluation value that is less affected by the level of correlation between two items corresponding to two adjacent axes.

[0034] Third Embodiment <Example of control device configuration> 6 is a block diagram showing another example of a control device according to the present disclosure. In FIG. 6, a control device 30 includes an acquisition unit 31, a comprehensive evaluation value calculation unit (first calculation unit) 32, and an integrated value calculation unit 33 (second calculation unit).

[0035] The acquisition unit 31 acquires a plurality of measurement value sets by acquiring a measurement value set at predetermined time intervals over a predetermined period of time. That is, the measurement timings of the plurality of measurement value sets are different from one another.

[0036] The overall evaluation value calculation unit 32 calculates an overall evaluation value for each measurement value set. The method of calculating the overall evaluation value by the overall evaluation value calculation unit 32 may be the same as that used by the above-mentioned overall evaluation value calculation unit 12 or the same as that used by the overall evaluation value calculation unit 22.

[0037] The integrated value calculation unit 33 calculates an integrated overall evaluation value by integrating the multiple overall evaluation values ​​calculated by the overall evaluation value calculation unit 32 for the multiple measurement value sets acquired by the acquisition unit 31.

[0038] Here, the acquisition unit 31 may acquire a set of measurement values ​​at predetermined time intervals for each of a plurality of predetermined periods. The plurality of predetermined periods may be, for example, four periods obtained by dividing 24 hours into six-hour periods (e.g., 0:00 to 6:00, 6:00 to 12:00, 12:00 to 18:00, and 18:00 to 24:00). The overall evaluation value calculation unit 32 may then calculate an overall evaluation value for each set of measurement values ​​for each predetermined period. The integrated value calculation unit 33 may then calculate an integrated overall evaluation value for each predetermined period.

[0039] <Example of control device operation> FIG. 7 is a flowchart showing another example of the processing operation of the control device of the present disclosure.

[0040] The acquisition unit 31 acquires a plurality of measurement value sets that are measured during a predetermined period and are measured at different timings (step S31).

[0041] The overall evaluation value calculation unit 32 calculates an overall evaluation value for each measurement value set (step S32).

[0042] The integrated value calculation unit 33 calculates an integrated overall evaluation value by integrating the multiple overall evaluation values ​​calculated for the multiple measurement value sets (step S33).

[0043] As described above, according to the third embodiment, the integrated value calculation unit 33 in the control device 30 calculates an integrated evaluation value by accumulating multiple overall evaluation values ​​calculated by the overall evaluation value calculation unit 32 for multiple measurement value sets acquired by the acquisition unit 31.

[0044] This configuration of the control device 30 makes it possible to calculate an integrated comprehensive evaluation value, which is an evaluation index that smooths out the effects of instantaneous fluctuations in the comprehensive evaluation value over time for a predetermined period of time. By using this integrated comprehensive evaluation value for evaluation, it is possible to improve the accuracy of the evaluation.

[0045] <Fourth embodiment> 8 is a block diagram showing another example of a control device according to the present disclosure. In FIG. 8, a control device 40 includes an acquisition unit 31, a comprehensive evaluation value calculation unit (first calculation unit) 32, an integrated value calculation unit (second calculation unit) 33, and an evaluation unit 41.

[0046] The evaluation unit 41 evaluates the evaluation object based on the integrated comprehensive evaluation value calculated by the integrated value calculation unit 33. Here, the evaluation object is a network slice. For example, as described above, when the integrated value calculation unit 33 calculates the integrated comprehensive evaluation value for each of a plurality of predetermined periods, the evaluation unit 41 can quantitatively evaluate the network slice by classifying the evaluation value (e.g., level 1 to 10) based on the integrated comprehensive evaluation value for each predetermined period. Specifically, the larger the integrated value, the better the quality of the network slice is considered to be. By doing so, the quality of the network slice can be confirmed at the time each measurement value set is acquired. Note that this may also be applied to determining which time period is appropriate for using a network slice, which network slice should be used, the motivation for changing the network slice settings, etc.

[0047] Here, the network slice is provided to a customer such as a company, etc. If an evaluation result for the network slice for each predetermined period is obtained as described above, a usage fee for the network slice for each predetermined period can be set based on this evaluation result.

[0048] <Other embodiments> FIG. 9 is a diagram illustrating an example of the configuration of a control device. In FIG. 9, the control device 100 includes a processor 101, a memory 102, and an interface 103. The processor 101 may be, for example, a microprocessor, a microprocessing unit (MPU), or a central processing unit (CPU). The processor 101 may include multiple processors. The memory 102 is configured by a combination of a volatile memory and a nonvolatile memory. The memory 102 may include storage located away from the processor 101. In this case, the processor 101 may access the memory 102 via an input / output (I / O) interface (not shown).

The acquisition units 11, 21, and 31, the comprehensive evaluation value calculation units 12, 22, and 32, the integrated value calculation unit 33, and the evaluation unit 41 of the control devices 10, 20, 30, and 40 of the first to fourth embodiments may be realized by the processor 101 reading and executing a program stored in the memory 102. That is, the control devices 10, 20, 30, and 40 of the first to fourth embodiments can be realized by software. The program can be stored using various types of non-transitory computer-readable media and supplied to a computer. The non-transitory computer-readable media include various types of tangible storage media. Examples of non-transitory computer-readable media include magnetic recording media (e.g., flexible disks, magnetic tapes, hard disk drives), magneto-optical recording media (e.g., magneto-optical disks), CD-ROMs (Read Only Memory), CD-Rs, CD-R / Ws, DVDs (Digital Versatile Discs), semiconductor memories (e.g., mask ROMs, PROMs (Programmable ROMs), EPROMs (Erasable PROMs), flash ROMs, and RAMs (Random Access Memory). The program may also be supplied to a computer by various types of transitory computer-readable media. Examples of transitory computer-readable media include electric signals, optical signals, and electromagnetic waves. The transitory computer-readable medium can supply the program to a computer via a wired communication path such as an electric wire or optical fiber, or via a wireless communication path.
