Summary of the Invention

Problems to be Solved by the Invention

[0004] In network construction, when a difference arises between measured quality and target value for some reason, such as when the measured quality deteriorates compared to the target value, which is a quality value determined by prior environmental simulations, reducing the time and cost required for countermeasures through root cause analysis becomes a challenge. The system described in Patent Document 1 acquires environmental information indicating the environment in which the receiver is placed, associates the receiver's communication state with the content reception format according to the acquired environmental information, determines evaluation criteria, and controls the receiver so that it can receive in an appropriate format according to the communication state based on the determined evaluation criteria.

[0005] However, in Patent Document 1, the environmental information to be acquired is information about the receiver and its surroundings, and the target of control based on the determined evaluation criteria is also the receiver. Therefore, if the cause of deterioration in communication quality or application quality is not the receiver and its surroundings that are subject to quality control, but rather communication involving other devices not subject to quality control that share the communication path, communication environment, etc., or another application not subject to quality control that communicates simultaneously within the same terminal, these cannot be controlled, and there is a problem that the receiver cannot be controlled to receive in an appropriate form according to the communication state.

[0006] This disclosure has been made in view of the above, and aims to provide a parameter adjustment content calculation device capable of improving the accuracy of improving the communication quality of communications subject to quality control. [Means for solving the problem]

[0007] To solve the aforementioned problems and achieve the objectives, the parameter adjustment content calculation device of this disclosure comprises: an information acquisition unit that acquires parameters set in one or more communication systems that conduct multiple communications, and quality information of communications subject to quality control among the multiple communications; a design information knowledge acquisition unit that acquires design information of one or more communication systems, and knowledge used to calculate parameter adjustment content for adjusting parameters; an information storage unit that stores the parameters and quality information acquired by the information acquisition unit as information, and stores the design information and knowledge acquired by the design information knowledge acquisition unit as information; a parameter adjustment content calculation unit that calculates parameter adjustment content based on the information stored in the information storage unit; and a parameter adjustment content output unit that outputs parameter adjustment content to the communication system whose parameters are adjusted by the parameter adjustment content. When the information acquisition unit acquires parameters from one or more communication systems, it acquires parameters set for the communication system that conducts communications subject to quality control, as well as parameters set for communication systems that share the same communication environment as the communication system that conducts communications subject to quality control and that conduct communications not subject to quality control. The communication system that conducts communications subject to quality control and the communication system that conducts communications not subject to quality control include application terminals used for communication by applications. Communication systems that perform communications subject to quality control and communication systems that perform communications not subject to quality control differ in at least one of the included devices and the applications used in the communications. Stored in the information storage unit The information is characterized by including parameters that can be set in the actual environment where communication systems that perform communications subject to quality control and communication systems that perform communications not subject to quality control are installed.

[0010] The parameter adjustment content calculation device, control circuit, storage medium, and parameter adjustment content calculation method according to embodiments of this disclosure will be described in detail below with reference to the drawings.

[0011] Embodiment 1. Figure 1 shows an example configuration of the parameter adjustment system 1 according to Embodiment 1. The parameter adjustment system 1 comprises a parameter adjustment content calculation device 10, a communication system 30, and a communication system 40. Communication systems 30 and 40 are communication networks installed in the actual environment 20, that is, in the same communication environment. Of these, communication system 30 is a communication network that performs quality-controlled communications whose communication quality is controlled by the parameter adjustment content calculation device 10. Communication system 40 is a communication network that performs non-quality-controlled communications whose communication quality is not controlled by the parameter adjustment content calculation device 10.

[0012] Communication system 30 includes an application user terminal 31 connected to a transmitting device 32, a transmitting device 32, a communication channel 33, a receiving device 34, and an application user terminal 35 connected to the receiving device 34. In communication system 30, the transmitting device 32 and the receiving device 34 perform quality-controlled communication via the communication channel 33 for application user terminals 31 and 35 to communicate using a certain application. Communication system 40 includes an application user terminal 41 connected to a transmitting device 42, a transmitting device 42, a communication channel 43, a receiving device 44, and an application user terminal 45 connected to the receiving device 44. In communication system 40, the transmitting device 42 and the receiving device 44 perform non-quality-controlled communication via the communication channel 43 for application user terminals 41 and 45 to communicate using a certain application. In the following explanation, when app-using devices 31, 35, 41, and 45 are not distinguished, they will simply be referred to as "devices," and when transmitting devices 32, 42 and receiving devices 34, 44 are not distinguished, they will be referred to as "base stations." Also, when communication channels 33 and 43 are not distinguished, they will be referred to as "communication channels." Furthermore, devices and base stations together may be referred to as "devices." A device may include communication channels.

[0013] Regarding an application example of the parameter adjustment system 1, for example, there is a platform monitoring system from aboard a vehicle using a surveillance camera installed at a station in the railway field. Regarding the parameter adjustment system 1, among others, there are applications to communication systems for mobility aimed at autonomous driving using V2X (Vehicle to Everything), applications when constructing a network in a specific area such as the installation of local 5G (5th Generation) or Wi-Fi (registered trademark) in an urban area or an event venue, etc. Also, regarding the parameter adjustment system 1, different from quality control by network slices, it is possible to apply it to multiple communication systems within the same slice.

[0014] The parameter adjustment content calculation device 10, together with the communication system 30 that performs communication subject to quality control, also performs acquisition of information, output of parameter adjustment content, etc. for a communication system 40 that performs communication not subject to quality control but uses the same communication environment, that is, the actual environment 20, although different from the communication system 30 and devices, etc. The parameter adjustment content calculation device 10 automatically or manually acquires, as information, communication quality or application quality subject to quality control, parameters set in devices, communication paths, surrounding environments, etc. on the actual environment 20, design information of each device, knowledge, domain knowledge of specialized fields, etc. Also, the parameter adjustment content calculation device 10 outputs, as output, parameter adjustment content that is optimal for the network, that is, optimal for the communication system 30 that performs communication subject to quality control, and reflects it automatically or manually on the corresponding device on the actual environment 20.

[0015] The parameter adjustment content calculation device 10 accumulates various design information necessary for constructing a communication network by the communication systems 30 and 40, the correspondence between the parameters set in each device of the communication systems 30 and 40 and the communication quality of the communication system 30, etc. Using the information about the communication system 30 that performs communication subject to quality control and the information about the communication system 40 that performs communication not subject to quality control, it calculates the parameter adjustment content for improving the communication quality of the communication subject to quality control in the communication system 30. The parameter adjustment content calculation device 10 outputs the parameter adjustment content to at least the communication system including the device to be adjusted among the communication systems 30 and 40, thereby improving the communication quality of the communication system 30 that performs communication subject to quality control. In the parameter adjustment system 1, the parameter adjustment content calculation device 10 may output the parameter adjustment content only to the communication system including the device to be adjusted among the communication systems 30 and 40, or may output the parameter adjustment content to the communication systems 30 and 40. In either case, in the communication systems 30 and 40, the device targeted by the parameter adjustment content adjusts the parameter based on the parameter adjustment content, and the device not targeted by the parameter adjustment content ignores the parameter adjustment content.

[0016] Next, the detailed configuration and operation of the parameter adjustment content calculation device 10 will be described. FIG. 2 is a diagram showing a configuration example of the parameter adjustment content calculation device 10 according to Embodiment 1. The parameter adjustment content calculation device 10 includes an information acquisition unit 11, a design information knowledge acquisition unit 12, an information storage unit 13, a parameter adjustment content calculation unit 14, and a parameter adjustment content output unit 15.

[0017] The information acquisition unit 11 acquires parameters set in one or more communication systems where multiple communications take place, and quality information of the communication subject to quality control among the multiple communications. Quality information is information indicating the communication quality of a communication, and in this case, it is information indicating the communication quality of the communication subject to quality control. In Embodiment 1, the information acquisition unit 11 acquires parameters set in communication systems 30 and 40, each performing different communications, and quality information of the communication subject to quality control performed by communication system 30. The quality information of communication system 30 may be measured by each device of communication system 30, or it may be measured by sensors outside the devices of communication system 30. The information acquisition unit 11 connects to devices, communication paths, surrounding environments, etc. on the actual environment 20, or to a terminal device (not shown) used by the user of the parameter adjustment content calculation device 10, and acquires information as an interface that accepts any input.

[0018] The design information knowledge acquisition unit 12 acquires design information for one or more communication systems and knowledge used to calculate parameter adjustments for adjusting parameters. The design information knowledge acquisition unit 12 acquires design information for devices included in one or more communication systems as design information and acquires domain knowledge used to calculate parameter adjustments for adjusting parameters as knowledge. In Embodiment 1, the design information knowledge acquisition unit 12 acquires design information for communication systems 30 and 40 and knowledge used to calculate parameter adjustments for adjusting parameters. The design information knowledge acquisition unit 12 functions as an input interface for acquiring design information for each device in communication systems 30 and 40, and domain knowledge such as necessary specialized fields.

[0019] The information storage unit 13 stores the parameter and quality information acquired by the information acquisition unit 11 as information, and the design information and knowledge acquired by the design information knowledge acquisition unit 12 as information. The information storage unit 13, for example, has a database and stores the information acquired by the information acquisition unit 11 and the design information knowledge acquisition unit 12 in the database.

[0020] The parameter adjustment content calculation unit 14 calculates the parameter adjustment content based on the information stored in the information storage unit 13. That is, the parameter adjustment content calculation unit 14 calculates the parameter adjustment content using the information acquired by the information acquisition unit 11 and the information acquired by the design information knowledge acquisition unit 12.

[0021] The parameter adjustment content output unit 15 outputs the parameter adjustment content to the communication systems 30 and 40, whose parameters are adjusted according to the parameter adjustment content. The parameter adjustment content output unit 15 is connected to devices, communication paths, and surrounding environments in the actual environment 20, or to terminal devices (not shown) used by the user of the parameter adjustment content calculation device 10, and functions as an output interface.

[0022] Here, we will explain the various types of information acquired by the parameter adjustment calculation device 10.

[0023] Figure 3 shows an example of quality information acquired by the information acquisition unit 11 of the parameter adjustment content calculation device 10 according to Embodiment 1. Communication or application quality information includes information about image transmission applications or video transmission applications, voice transmission applications, other applications, networks, physical environments, etc.

[0024] Quality information for image or video transmission applications includes PSNR (Peak Signal-to-Noise Ratio), SSIM (Structural SIMilarity Index), the number and percentage of frame losses for a specified type of frame, the number and percentage of frame losses for I (Intra-coded), P (Predicted), and B (Bi-directional predicted) frames, the total number and percentage of frame losses for all types of frames, and information on the distribution of frame losses for each frame.

[0025] Furthermore, quality information for voice transmission applications includes Q (Quality) values ​​and MOS (Mean Opinion Score) values.

[0026] Other application quality information includes application-level metrics such as end-to-end latency, file transfer time, and various defined subjective evaluation metrics.

[0027] Furthermore, network quality information includes packet loss count, packet loss distribution information, network delay and delay jitter measured by specified commands such as the ping command, and throughput.

[0028] Furthermore, quality information for the physical environment includes RSSI (Received Signal Strength Indicator), RSRP (Reference Signal Received Power), RSRQ (Reference Signal Received Quality), SNR (Signal to Noise Ratio), SINR (Signal to Interference and Noise Ratio), delay due to radio wave propagation delay dependent on the communication channel, delay jitter due to radio wave propagation delay dependent on the communication channel, effective spread in the delay profile, number of effective paths in the delay profile, and rice factor.

[0029] The above quality information is just an example, and the information acquisition unit 11 may acquire quality information other than that exemplified above.

[0030] Figure 4 shows an example of set parameters acquired by the information acquisition unit 11 of the parameter adjustment content calculation device 10 according to Embodiment 1. The set parameters are parameters set for each device provided by the communication systems 30 and 40. The set parameters include those related to the application and those related to the physical environment. Parameters related to the application, i.e., parameters set for the application, include common parameters, parameters related to voice such as VoIP (Voice over Internet Protocol), parameters related to images or video, and parameters related to file transmission such as FTP (File Transfer Protocol). Parameters set for the physical environment include those related to the physical environment or the communication environment.

[0031] Among the parameters set for an application, common parameters include the type of application used, the number of applications used simultaneously, packet transmission timing, and the receive buffer size.

[0032] Furthermore, parameters for voice transmission such as VoIP include codec type and packet conversion cycle.

[0033] Furthermore, parameters for image or video transmission include codec type, resolution, frame rate, transmission bitrate, I-frame interval, and protocol type.

[0034] Additionally, file transfer parameters such as FTP include file types such as TCP (Transmission Control Protocol) and UDP (User Datagram Protocol).

[0035] Among the parameters set for the physical environment, the physical environment or communication environment includes the reflector position, the position, height and angle of base stations such as transmitters or receivers included in the communication system, the number, position and height and movement path, speed and acceleration of terminals such as application-using terminals included in the communication system, the network topology between each base station and each terminal, the type of wireless communication, the combination of wireless communication types in redundancy in multiple wireless communication, the number of HARQ (Hybrid Automatic Repeat reQuest) counts, the ratio of UL (UpLink) and DL (DownLink) in the specified communication method, the modulation scheme, the center frequency and channel, the bandwidth, the numerology, and the transmit power.

[0036] Note that the above parameters are just examples, and the information acquisition unit 11 may acquire parameters other than those exemplified above.

[0037] Figure 5 shows an example of design information for terminals and base stations acquired by the design information knowledge acquisition unit 12 of the parameter adjustment content calculation device 10 according to Embodiment 1. The design information for terminals and base stations includes information on antennas, radio wave characteristics, frequency characteristics, network characteristics, power supply requirements, physical design, security, etc.

[0038] Antenna design information includes antenna pattern, directivity, gain, polarization, full width at half maximum, sidelobe level, antenna position and direction, number and spacing, impedance characteristics, feedline characteristics, antenna shape and material, etc.

[0039] The radio wave characteristics of the device include transmission power, reception sensitivity, radio wave propagation model, and characteristics against obstacles, multipath propagation, and fading.

[0040] Frequency characteristics include operating frequency, bandwidth, frequency response, and channel allocation.

[0041] Network characteristics include cell size, cell planning, threshold settings for handover, network topology, and traffic management settings.

[0042] Power supply requirements include battery capacity and lifespan, power efficiency, and more.

[0043] Physical design considerations include size, weight, durability, and environmental resistance to temperature and humidity.

[0044] Security aspects include encryption methods, authentication methods, and access control specifications.

[0045] The above design information is just an example, and the design information knowledge acquisition unit 12 may acquire design information other than that exemplified above.

[0046] Next, we will describe the operation of the parameter adjustment content calculation device 10 in which it acquires and stores quality information and set parameter information from the actual environment 20, calculates the parameter adjustment content, and outputs it. Figure 6 is a flowchart showing the operation of the parameter adjustment content calculation device 10 according to Embodiment 1. In the parameter adjustment content calculation device 10, it is assumed that the design information knowledge acquisition unit 12 acquires design information, knowledge, domain knowledge, etc. in advance as a preliminary operation before the start of the operation shown in the flowchart in Figure 6, and stores and holds it in the information storage unit 13, and also acquires the target value of quality information that the communication subject to quality control should take, and stores and holds it in the information storage unit 13. The timing of the acquisition of design information knowledge by the design information knowledge acquisition unit 12 is not particularly limited, and it may be updated as needed, or it is sufficient that it can be reflected in the parameter adjustment content calculation unit 14 when the parameter adjustment content calculation unit 14 calculates the parameter adjustment content.

[0047] Target values ​​can be set according to defined criteria, such as upper limits, lower limits, and thresholds for the target range. This includes lower thresholds for quality to be improved to a specific value after quality degradation, and upper thresholds for quality suppression to conserve network resources. Furthermore, target values ​​do not have to be set as a single value; different values ​​may be assigned depending on the conditions. For example, target values ​​can be expressed as a correspondence between different combinations of parameter values, or in any other format that serves as a guideline for calculating parameter adjustments.

[0048] Furthermore, the information acquisition unit 11 of the parameter adjustment content calculation device 10 will, as a preliminary operation before the start of the flowchart shown in Figure 6, store in the information storage unit 13 a database of combinations of quality information previously acquired from each device of the communication system 30 and parameters set for each device of the communication systems 30 and 40.

[0049] First, in the parameter adjustment content calculation device 10, the information acquisition unit 11 acquires quality information about the communication subject to quality control from the communication system 30 (step S1). For example, under the condition that the communication systems 30 and 40 are operating in parallel, the information acquisition unit 11 acquires quality information and combinations of set parameters from base stations, terminals, communication paths, other devices on the network, and the surrounding physical environment. The environmental conditions of the devices to be acquired may be the actual environment 20 or a simulation. The type of communication here may be any type of wired environment such as Ethernet® or optical fiber, or any type of wireless environment such as W-CDMA (Wideband-Code Division Multiple Access), 4G (4th Generation) / LTE (Long Term Evolution), 5G / NR (New Radio), Wi-Fi, Bluetooth®, Zigbee®, Wi-SUN (Wireless-Smart Utility Network), SigFox®, or LoRaWAN (Long Range Wide Area Network). Furthermore, the method for acquiring various types of information at this time may be that the information acquisition unit 11 acquires the information by directly connecting to base stations, terminals, communication channels, other devices, the surrounding physical environment, etc., or the user of the parameter adjustment content calculation device 10 may manually input the information from an external source using an interface.

[0050] The information that the parameter adjustment calculation device 10 takes as input includes any or a combination of the quality information described in Figure 3, any or a combination of the parameter information described in Figure 4, and any or a combination of the design information described in Figure 5. The parameter adjustment calculation device 10 may take any information as input as long as it can be quantified. The parameter adjustment calculation device 10 holds and stores multiple sets of the information acquired here. The parameter adjustment calculation device 10 may continue to hold all elements included in the information, discard some as needed at a specified timing, or add information at a specified timing.

[0051] The communication system 30 that performs the communication subject to quality control may include an image transmission system, a video transmission system, an audio transmission system, a file transmission system, and any other information transmission system whose quality can be quantitatively evaluated.

[0052] The information acquisition unit 11 compares the acquired quality information with the target value and determines whether there is a difference between the quality information and the target value (step S2). If there is no difference between the quality information and the target value (step S2: No), the information acquisition unit 11 returns to step S1. The information acquisition unit 11 waits until it can acquire quality information about the communication subject to quality control from the communication system 30. For example, the information acquisition unit 11 performs the operation of step S1 at a predetermined interval.

[0053] If there is a difference between the quality information and the target value (Step S2: Yes), the information acquisition unit 11 proceeds to Step S3. That is, in the parameter adjustment content calculation device 10, if there is a difference between the current quality information and the target value for some reason, such as the quality information obtained by actual measurement being worse than the quality value evaluated by simulation, the information acquisition unit 11 acquires information necessary for calculating the parameter adjustment content from base stations, terminals, communication paths, other devices, and the surrounding physical environment inside and outside the network (Step S3). In Step S1, the information acquisition unit 11 only needed to acquire the quality information of the communication system 30 that performs the communication subject to quality control, but now it acquires parameter information for communication systems 40 that perform communication not subject to quality control, in addition to the communication system 30 that performs the communication subject to quality control.

[0054] The information acquisition unit 11 stores the acquired information in the information storage unit 13 (step S4). The information acquisition unit 11 may add the information acquired in step S3 to the information already stored. The information acquisition unit 11 may choose to acquire the information in step S3 according to a list of information types already stored, or it may add and store new types of information.

[0055] In the parameter adjustment calculation device 10, the parameter adjustment calculation unit 14 uses the information stored in the information storage unit 13 to calculate the optimal parameter adjustment content to reduce the difference between the quality information of the communication subject to quality control performed in the communication system 30 and the target value (step S5). The parameter adjustment calculation unit 14 may calculate the parameter adjustment content using statistical analysis such as regression analysis or optimization, mathematical analysis methods, or machine learning. Furthermore, the parameter adjustment calculation unit 14 may add constraints during calculation based on whether the parameters adjusted by the parameter adjustment content are within the range that can actually be operated in the real environment 20, or it may evaluate the feasibility of the calculated parameter adjustment content. The quality information subject to control by the parameter adjustment content includes any or a combination of the quality information described in Figure 3.

[0056] In the parameter adjustment content calculation device 10, the parameter adjustment content output unit 15 outputs the parameter adjustment content calculated by the parameter adjustment content calculation unit 14 (step S6). The parameter adjustment content output unit 15 may also automatically reflect the parameter adjustment content by actually adjusting the parameters in the corresponding base station, terminal, communication channel, other devices, surrounding physical environment, etc. in the actual environment 20.

[0057] Here, the input and output destinations for various types of information in the parameter adjustment content calculation device 10 may include a communication system 40 that performs communication that is not subject to quality control. That is, the parameter adjustment content calculation device 10 may reflect the parameter adjustment content based on information obtained from the communication system 40 that is not subject to quality control to the device of the communication system 40 that is not subject to quality control, or it may reflect the parameter adjustment content based on information obtained from the communication system 30 that is subject to quality control to the device of the communication system 40 that is not subject to quality control, or it may reflect the parameter adjustment content based on information obtained from the communication system 40 that is not subject to quality control to the device of the communication system 30 that is subject to quality control.

[0058] As a result, the expected effect is that the parameter adjustment calculation device 10 can suppress interference by reducing the output of the equipment in the communication system 40 that is not subject to quality control if radio interference from equipment in the communication system 40 that is not subject to quality control is the cause of quality degradation, thereby indirectly improving the quality information of the communication system 30 that is subject to quality control. Furthermore, if bandwidth congestion caused by equipment in the communication system 40 that is not subject to quality control and shares the communication bandwidth with the communication system 30 that is subject to quality control is the cause of quality degradation, the parameter adjustment calculation device 10 can increase the usable traffic of the communication system 30 that is subject to quality control by limiting the bandwidth occupied by the equipment in the communication system 40 that is not subject to quality control, thereby indirectly improving the quality information of the communication system 30 that is subject to quality control.

[0059] As a method for reflecting the parameter adjustments, the parameter adjustment calculation device 10 may reflect the parameter adjustments by connecting to the device in the actual environment 20 where the parameters are adjusted according to the parameter adjustments and directly manipulating the parameters. Alternatively, the user of the parameter adjustment calculation device 10 may be made able to confirm the parameter adjustments using text, images, or audio on the interface. In addition, the device may prompt the user to reflect the adjustments to the device in the actual environment 20 by giving instructions such as messages. The parameters adjusted according to the parameter adjustments include any or a combination of the parameters described in Figure 4. Thus, in the parameter adjustment calculation device 10, the parameter adjustment output unit 15 may present the parameter adjustments to the user so that the user who has confirmed the parameter adjustments can manually reflect the parameter adjustments to the communication system whose parameters are being adjusted. Alternatively, if the parameter adjustment output unit 15 and the communication system whose parameters are being adjusted are connected, the parameter adjustments may be directly reflected to the communication system whose parameters are being adjusted.

[0060] After the completion of step S6, the parameter adjustment calculation device 10 performs the operation of step S1, for example, after a period of time based on a specified cycle has elapsed since the previous operation of step S1. The parameter adjustment calculation device 10 then repeats the above operation.

[0061] Thus, in the parameter adjustment content calculation device 10, when the information acquisition unit 11 acquires parameters from one or more communication systems, it acquires parameters set for communication subject to quality control, as well as parameters set for communication not subject to quality control. The parameter adjustment content output unit 15 outputs the parameter adjustment content to at least one of the communication systems that perform communication subject to quality control, namely the communication system whose parameters are adjusted according to the parameter adjustment content, namely the communication system 30 that performs communication subject to quality control and the communication system 40 that performs communication not subject to quality control.

[0062] In Embodiment 1, in the parameter adjustment content calculation device 10, the timing of the information acquisition unit 11 acquiring parameter and quality information is controlled by the information acquisition unit 11, and the timing of the parameter adjustment content calculation unit 14 calculating the parameter adjustment content is controlled by the parameter adjustment content calculation unit 14. Furthermore, in the parameter adjustment content calculation device 10, the timing of transmitting the parameter adjustment content from the parameter adjustment content output unit 15 to the communication system in which the parameters are adjusted, and the timing of reflecting the parameter adjustment content in the actual control of the communication system in which the parameters are adjusted, are controlled by the parameter adjustment content output unit 15.

[0063] Next, the hardware configuration of the parameter adjustment content calculation device 10 will be described. In the parameter adjustment content calculation device 10, the information acquisition unit 11, the design information knowledge acquisition unit 12, the information storage unit 13, the parameter adjustment content calculation unit 14, and the parameter adjustment content output unit 15 are realized by the hardware configuration shown in Figure 7 or Figure 8. Figure 7 is the first diagram showing an example of the hardware configuration of the parameter adjustment content calculation device 10 according to Embodiment 1. Figure 8 is the second diagram showing an example of the hardware configuration of the parameter adjustment content calculation device 10 according to Embodiment 1. The difference between Figure 7 and Figure 8 is that the memory 93 and CPU (Central Processing Unit) 94 in Figure 7 are realized by the processing circuit 96 in Figure 8. The processing circuit 96 is also called a control circuit.

[0064] In the parameter adjustment content calculation device 10, the information acquisition unit 11 and the design information knowledge acquisition unit 12 are implemented by the information acquisition interface termination unit 91 and the memory 93 and CPU 94, or the processing circuit 96. The information storage unit 13 and the parameter adjustment content calculation unit 14 are implemented by the memory 93 and CPU 94, or the processing circuit 96. The parameter adjustment content output unit 15 is implemented by the parameter adjustment content output interface termination unit 92 and the memory 93 and CPU 94, or the processing circuit 96. In the example in Figure 7, the power supply circuit 95 supplies power to the CPU 94, and in the example in Figure 8, it supplies power to the processing circuit 96.

[0065] In the hardware configuration shown in Figure 7, each function of the parameter adjustment calculation device 10 is realized by software, firmware, or a combination of software and firmware. The software or firmware is written as a program and stored in memory 93. In the example in Figure 7, each function is realized by the CPU 94 reading and executing the program stored in memory 93. This program can also be said to be a program that causes the parameter adjustment calculation device 10 to execute each function realized by the CPU 94. This program may be provided by a storage medium on which the program is stored, or by other means such as a communication medium.

[0066] The above program can also be described as a program that causes the parameter adjustment content calculation device 10 to execute the following steps: an information acquisition step in which the information acquisition unit 11 acquires parameters set in one or more communication systems where multiple communications take place, and quality information of the communication subject to quality control among the multiple communications; a design information knowledge acquisition step in which the design information knowledge acquisition unit 12 acquires design information of one or more communication systems and knowledge used to calculate parameter adjustment content for adjusting parameters; an information storage step in which the information storage unit 13 stores the parameters and quality information acquired by the information acquisition unit 11 as information, and stores the design information and knowledge acquired by the design information knowledge acquisition unit 12 as information; a parameter adjustment content calculation step in which the parameter adjustment content calculation unit 14 calculates the parameter adjustment content based on the information stored in the information storage unit 13; and a parameter adjustment content output step in which the parameter adjustment content output unit 15 outputs the parameter adjustment content to the communication system whose parameters are adjusted by the parameter adjustment content.

[0067] In Figure 7, the CPU 94 is, for example, a processing unit, arithmetic unit, microprocessor, microcomputer, or DSP (Digital Signal Processor). The memory 93 is, for example, a non-volatile or volatile semiconductor memory such as RAM (Random Access Memory), ROM (Read Only Memory), flash memory, EPROM (Erasable Programmable ROM), EEPROM (Registered Trademark) (Electrically EPROM), magnetic disks, flexible disks, optical disks, compact disks, minidiscs, or DVDs (Digital Versatile Discs).

[0068] Furthermore, in Figure 8, the processing circuit 96 can be, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or a combination thereof. The parameter adjustment calculation device 10 may also be configured such that some functions are implemented by the memory 93 and CPU 94, and other functions are implemented by the processing circuit 96. In other words, the parameter adjustment calculation device 10 may implement some functions with dedicated hardware and others with software or firmware. Thus, the parameter adjustment calculation device 10 can implement each of the above functions using dedicated hardware, software, firmware, or a combination thereof.

[0069] As described above, according to this embodiment, the parameter adjustment content calculation device 10 stores the correspondence between various necessary design parameters and quality information during network construction, etc., calculates the optimal parameter adjustment content for quality control using communication information from other devices, other applications, etc., and outputs it to the parameter to be adjusted. As a result, when a difference occurs between the current quality information and the target value due to some problem, such as when the actual quality value, i.e., quality information, deteriorates compared to the quality value obtained by simulation evaluation during network construction, etc., the parameter adjustment content calculation device 10 can shorten the time required for cause analysis and countermeasures.

[0070] The parameter adjustment calculation device 10 acquires information such as parameters for both the communication system 30 subject to quality control and the communication system 40 not subject to quality control in a real environment 20 where multiple communications are taking place. The parameter adjustment calculation device 10 not only adjusts the parameters of the communication system 30 subject to quality control, but also adjusts the parameters of the communication system 40 not subject to quality control if adjusting the parameters of the communication system 40 not subject to quality control can improve the quality information of the communication system 30 subject to quality control. By performing such control, the parameter adjustment calculation device 10 can improve the accuracy of improving the communication quality of the communication subject to quality control compared to cases where the parameters of the communication system 40 not subject to quality control cannot be adjusted, such as when the communication quality of the communication subject to quality control deteriorates, and further improve the efficiency of quality degradation countermeasures.

[0071] In Embodiment 1, the parameter adjustment system 1 was described as having one communication system 30 for quality control-targeted communications and one communication system 40 for non-quality control-targeted communications in the actual environment 20, but it is not limited to this. The parameter adjustment system 1 can also have two or more communication systems 30 for quality control-targeted communications and two or more communication systems 40 for non-quality control-targeted communications in the actual environment 20.

[0072] Furthermore, in Embodiment 1, the parameter adjustment content calculation device 10 did not acquire quality information from the communication system 40 which is not subject to quality control, but it may acquire quality information from the communication system 40 which is not subject to quality control. For example, in cases where the quality information of the communication system 40 deteriorates as a result of adjusting the parameters of the communication system 40 due to the parameter adjustment content, the parameter adjustment content calculation device 10 may calculate the parameter adjustment content within a range where the quality information of the communication system 40 does not fall below a specified value, or within a range where communication in the communication system 40 can be maintained.

[0073] Embodiment 2. Embodiment 1 described a case where a communication system 30 that performs quality-controlled communications and a communication system 40 that performs communications not subject to quality control jointly use the same communication environment, i.e., the actual environment 20, but the terminals, base stations, communication paths, etc., are all different. Embodiment 2 describes a case where a communication system 40a that shares an application user terminal 31 and a transmitting device 32 with the quality-controlled communication system 30a, but has a different receiving device 44 and application user terminal 45 than the receiving device 34 and application user terminal 35, jointly uses the same communication environment, i.e., the actual environment 20, as the communication system 30a.

[0074] Figure 9 shows an example configuration of the parameter adjustment system 1a according to Embodiment 2. The parameter adjustment system 1a comprises a parameter adjustment content calculation device 10, a communication system 30a, and a communication system 40a. Communication systems 30a and 40a are communication networks installed in the actual environment 20, that is, in the same communication environment. Of these, communication system 30a is a communication network that performs communication for quality control targets by the parameter adjustment content calculation device 10. Communication system 30a has the same configuration as communication system 30 of Embodiment 1. In communication system 30a, the transmitting device 32 communicates with the receiving device 34 for quality control targets via communication channel 33, and also communicates with the receiving device 44 for non-quality control targets via communication channel 43.

[0075] The communication system 40a is a communication network that performs communications that are not subject to quality control by the parameter adjustment content calculation device 10. The communication system 40a comprises a receiving device 44 and an application user terminal 45 connected to the receiving device 44. In order for application user terminals 31 and 45 to communicate using a certain application, the transmitting device 32 and the receiving device 44 perform communications that are not subject to quality control via the communication path 43.

[0076] In Embodiment 2, the parameter adjustment content calculation device 10 does not need to acquire information such as parameters from the application user terminal 41 and the transmission device 42, compared to Embodiment 1. However, in other respects, the parameter adjustment content calculation device 10 operates in the same way as in Embodiment 1. Furthermore, the parameter adjustment content calculation device 10 can achieve the same effects as in Embodiment 1 in Embodiment 2. Therefore, a detailed explanation of the configuration and operation of the parameter adjustment content calculation device 10 in Embodiment 2 is omitted.

[0077] Embodiment 3. Embodiment 3 describes a case in which a communication system 40b and a communication system 30b, which share a receiving device 34 and an application user terminal 35 with a communication system 30b subject to quality control, and which have different application user terminals 41 and transmitting device 42 than the application user terminal 31 and transmitting device 32, jointly use the same communication environment, i.e., the actual environment 20.

[0078] Figure 10 shows an example configuration of the parameter adjustment system 1b according to Embodiment 3. The parameter adjustment system 1b comprises a parameter adjustment content calculation device 10, a communication system 30b, and a communication system 40b. Communication systems 30b and 40b are communication networks installed in the actual environment 20, that is, in the same communication environment. Of these, communication system 30b is a communication network that performs communication for quality control targets by the parameter adjustment content calculation device 10. Communication system 30b has the same configuration as communication system 30 of Embodiment 1. In communication system 30b, the receiving device 34 communicates with the transmitting device 32 for quality control targets via communication channel 33, and also communicates with the transmitting device 42 for non-quality control targets via communication channel 43.

[0079] Communication system 40b is a communication network that performs communications that are not subject to quality control by the parameter adjustment content calculation device 10. Communication system 40b comprises an application user terminal 41 connected to a transmitting device 42, and the transmitting device 42. Communication system 40b allows application user terminals 41 and 35 to communicate using a certain application, and the transmitting device 42 and receiving device 34 perform communications that are not subject to quality control via a communication path 43.

[0080] In Embodiment 3, the parameter adjustment content calculation device 10 does not need to acquire information such as parameters from the receiving device 44 and the application user terminal 45, compared to Embodiment 1. However, in other respects, the parameter adjustment content calculation device 10 operates in the same way as in Embodiment 1 in Embodiment 3. Furthermore, the parameter adjustment content calculation device 10 can achieve the same effects as in Embodiment 1 in Embodiment 3. Therefore, a detailed explanation of the configuration and operation of the parameter adjustment content calculation device 10 in Embodiment 3 is omitted.

[0081] Embodiment 4. Embodiment 4 describes a case where the communication system 30c comprises an application user terminal 31, a transmitting device 32, a communication channel 33, a receiving device 34, and an application user terminal 35, and the transmitting device 32 and the receiving device 34 perform communication subject to quality control while simultaneously performing other communication as background traffic, i.e., communication not subject to quality control.

[0082] Figure 11 shows an example configuration of the parameter adjustment system 1c according to Embodiment 4. The parameter adjustment system 1c comprises a parameter adjustment content calculation device 10 and a communication system 30c. The communication system 30c is a communication network installed in the actual environment 20. The communication system 30c performs communication subject to quality control by the parameter adjustment content calculation device 10, as well as communication not subject to quality control. The communication system 30c has the same configuration as the communication system 30 of Embodiment 1. In the communication system 30c, the transmitting device 32 and the receiving device 34 perform communication subject to quality control in a first application via the communication path 33, and perform communication not subject to quality control in a second application different from the first application.

[0083] In Embodiment 4, the parameter adjustment content calculation device 10 does not need to acquire information such as parameters for the communication system 40, compared to Embodiment 1. However, in other respects, the parameter adjustment content calculation device 10 operates in the same way as in Embodiment 1. Furthermore, the parameter adjustment content calculation device 10 can achieve the same effects as in Embodiment 1 in Embodiment 4. Therefore, a detailed explanation of the configuration and operation of the parameter adjustment content calculation device 10 in Embodiment 4 is omitted.

[0084] Embodiment 5. Embodiment 5 describes a case where Embodiments 1 to 4 are combined.

[0085] Figure 12 shows an example configuration of the parameter adjustment system 1d according to Embodiment 5. The parameter adjustment system 1d comprises a parameter adjustment content calculation device 10, a communication system 30d, and a communication system 40d. Communication systems 30d and 40d are communication networks installed in the actual environment 20, that is, in the same communication environment. Of these, communication system 30d is a communication network that performs communication subject to quality control by the parameter adjustment content calculation device 10 using a first application, and performs communication not subject to quality control by the parameter adjustment content calculation device 10 using a second application. Communication system 30d has the same configuration as communication system 30 of Embodiment 1. In communication system 30d, the transmitting device 32 and the receiving device 34 perform communication subject to quality control using a first application and communication not subject to quality control using a second application via a communication path 33.

[0086] The communication system 40d is a communication network that performs communications that are not subject to quality control by the parameter adjustment content calculation device 10. The communication system 40d comprises an application user terminal 41 connected to the transmitting device 42, the transmitting device 42, a communication channel 43, a receiving device 44, and an application user terminal 45 connected to the receiving device 44. The communication system 40d performs the three types of communications that are not subject to quality control as described in Embodiments 1 to 3.

[0087] In Embodiment 5, the parameter adjustment content calculation device 10 operates in the same manner as in Embodiment 1. Furthermore, in Embodiment 5, the parameter adjustment content calculation device 10 can achieve the same effects as in Embodiment 1. Therefore, a detailed explanation of the configuration and operation of the parameter adjustment content calculation device 10 in Embodiment 5 is omitted.

[0088] Although the example in Figure 12 describes a combination of Embodiments 1 to 4, the method is not limited to this. Even when two or more embodiments from Embodiments 1 to 4 are combined, the parameter adjustment content calculation device 10 operates in the same way as in Embodiment 1, and the same effects as in Embodiment 1 can be obtained.

[0089] Embodiment 6. In Embodiments 1 to 5, the timing of the operation of each component in the parameter adjustment calculation device 10 was controlled by each component. Embodiment 6 describes a case in which the parameter adjustment calculation device 10e centrally manages the timing of the operation of each component.

[0090] Figure 13 shows an example of the configuration of the parameter adjustment content calculation device 10e according to Embodiment 6. The parameter adjustment content calculation device 10e comprises an information acquisition unit 11, a design information knowledge acquisition unit 12, an information storage unit 13, a parameter adjustment content calculation unit 14, a parameter adjustment content output unit 15, and a timing control unit 16. In Embodiment 6, the timing of information acquisition by the information acquisition unit 11, the timing of parameter adjustment content calculation by the parameter adjustment content calculation unit 14, the timing of transmission of parameter adjustment content by the parameter adjustment content output unit 15, and the timing of actually reflecting the parameter adjustment content by the parameter adjustment content output unit 15 are not determined by each individual component, but are determined collectively by the timing control unit 16 connected to each component.

[0091] Since these timings influence each other, the parameter adjustment calculation device 10e manages them collectively by the timing control unit 16 to prevent situations where the preceding process does not finish and the next process cannot proceed, or where the next process does not start even though it is ready to begin. As a result, the parameter adjustment calculation device 10e can acquire information, calculate parameter adjustments, and output parameter adjustments at an appropriate frequency without excess or deficiency, and it is expected that parameters can be adjusted in a shorter time and with less computation.

[0092] Furthermore, the timing control unit 16 may not control the timing of all of the operations listed above, but may control only the timing of some of the operations. Also, the timing control unit 16 may control the timing of the operations of each configuration by specifying a time, or by controlling the timing of the operations after a specified period has elapsed from a reference point at the start of control, or any method is not particularly limited as long as the timing of the operations of each configuration can be controlled.

[0093] Thus, the timing control unit 16 sets and manages at least one of the following: the timing at which the information acquisition unit 11 acquires parameter and quality information; the timing at which the parameter adjustment content calculation unit 14 calculates the parameter adjustment content; the timing at which the parameter adjustment content output unit 15 transmits the parameter adjustment content to the communication system in which the parameters are adjusted; and the timing at which the parameter adjustment content is reflected in the actual control in the communication system in which the parameters are adjusted.

[0094] In the parameter adjustment calculation device 10e, the operation of all parts except the timing control unit 16 is the same as that described in Embodiments 1 to 5. Furthermore, in Embodiment 6, the effect obtained by the parameter adjustment calculation device 10e is the same as that obtained in Embodiment 1.

[0095] Although not shown in the figures, the parameter adjustment content calculation device 10e is applicable to Embodiments 1 to 5. That is, in the parameter adjustment systems shown in Figures 1 and 9 to 12, the parameter adjustment content calculation device 10 can be replaced with the parameter adjustment content calculation device 10e.

[0096] The configurations shown in the above embodiments are merely examples, and it is possible to combine them with other known technologies, combine different embodiments, and omit or modify parts of the configuration without departing from the gist of the invention. [Explanation of Symbols]
