[Technical Field]

[0001] The present disclosure relates to the prioritized transmission of the latest data that is aggregated to a size that can be transmitted at one time or less. [Background technology]

[0002] The information provided in this Background section is intended only to enhance understanding of the general background of the present disclosure and should not be construed as an admission that the information is prior art known to those of ordinary skill in the art, nor should it be construed as suggesting in any way that prior art is known to those of ordinary skill in the art.

All features and their combinations presented in the embodiments are not necessarily essential to the present disclosure.

[0019] For convenience, the embodiments are presented by breaking down the embodiments into components for each function and / or each group of functions that realize the functions. However, one component in the embodiments may actually be realized by a combination of multiple separate components, or multiple components in the embodiments may actually be realized by a single integrated component. Furthermore, in describing the wireless communication system in the present embodiments, terminology in existing wireless communication standards such as 5G is used for convenience. This is not intended to limit the present disclosure to 5G or the like, and does not prevent the present disclosure from being applied when a technology similar to the present disclosure is provided under a different name in future wireless communication systems such as 6G.

[0020] FIG. 1 schematically illustrates an overview of a wireless communication system 1 according to an embodiment of the present disclosure. The wireless communication system 1 includes a 5G wireless communication system 11, a 4G wireless communication system 12, and a satellite communication system 13. The 5G wireless communication system 11 conforms to a fifth-generation mobile communication system (5G) that uses NR (New Radio) or 5G NR (Fifth Generation New Radio) as the radio access technology (RAT) and 5GC (Fifth Generation Core) as the core network (CN). The 4G wireless communication system 12 conforms to a fourth-generation mobile communication system (4G) that uses LTE (Long Term Evolution) or LTE-Advanced as the radio access technology and EPC (Evolved Packet Core) as the core network. The satellite communication system 13 provides satellite communication via a communication satellite 131. Although not shown in the figures, the wireless communication system 1 may include a wireless communication system of a generation earlier than 4G, a wireless communication system of a generation later than 5G (such as 6G), or any wireless communication system that is not associated with a generation such as Wi-Fi (registered trademark). Furthermore, the wireless communication system 1 may not include some or all of the 5G wireless communication system 11, the 4G wireless communication system 12, and the satellite communication system 13.

[0021] The 5G wireless communication system 11 includes communication devices 2A, 2B, 2C, and 2D (hereinafter collectively referred to as communication devices 2) such as smartphones that are installed on the ground and are also called UE (User Equipment) or UT (User Terminal), and multiple 5G base stations 111A, 111B, and 111C (hereinafter collectively referred to as 5G base stations 111) that can communicate via 5G NR. The base station 111 in 5G is also called a gNodeB (gNB). The communication range or support range of each of the 5G base stations 111A, 111B, and 111C is called a cell, and is illustrated as 112A, 112B, and 112C, respectively (hereinafter collectively referred to as 5G cells 112).

[0022] The size of the 5G cell 112 of each 5G base station 111 is arbitrary, but typically ranges from a few meters to tens of kilometers in radius. Although there is no established definition, cells with a radius of a few meters to tens of meters are called femtocells, cells with a radius of tens to tens of meters are called picocells, cells with a radius of tens to hundreds of meters are called microcells, and cells with a radius of more than hundreds of meters are called macrocells. 5G often uses high-frequency radio waves such as millimeter waves, and because of their high line-propagation ability, radio waves can be blocked by obstacles, shortening the communication distance. For this reason, 5G tends to use smaller cells than 4G and earlier generations.

[0023] A communication device 2 can perform 5G communication if it is located within at least one of multiple 5G cells 112A, 112B, and 112C. In the illustrated example, a communication device 2B located within 5G cells 112A and 112B can communicate with both 5G base stations 111A and 111B via 5G NR. Furthermore, a communication device 2C located within 5G cell 112C can communicate with 5G base station 111C via 5G NR. Communication devices 2A and 2D are located outside all of the 5G cells 112A, 112B, and 112C and are therefore unable to communicate via 5G NR. 5G communication via 5G NR between each communication device 2 and each 5G base station 111 is managed by the 5GC, which is a core network. For example, the 5GC handles data transmission and reception between each 5G base station 111, data transmission and reception between EPC, a satellite communication system 13, and external networks such as the Internet, and mobility management of the communication device 2.

[0024] The 4G wireless communication system 12 includes multiple 4G base stations 121 (only one is shown in FIG. 1). The multiple 4G base stations 121 are installed on the ground and are capable of communicating with the communication device 2 via LTE or LTE-Advanced. In 4G, the base station 121 is also called an eNodeB (eNB). Like each 5G base station 111, the communication range or support area of ​​each 4G base station 121 is also called a cell, and is illustrated as 122.

[0025] The communication device 2 can perform 4G communication if it is located inside the 4G cell 122. In the illustrated example, the communication devices 2A and 2B located inside the 4G cell 122 can communicate with the 4G base station 121 via LTE or LTE-Advanced. The communication devices 2C and 2D are located outside the 4G cell 122 and are therefore unable to communicate via LTE or LTE-Advanced. The 4G communication between each communication device 2 and each 4G base station 121 via LTE or LTE-Advanced is managed by the EPC, which is a core network. For example, the EPC handles the exchange of data with each 4G base station 121, the exchange of data with external networks such as 5GC, the satellite communication system 13, and the Internet, and the mobility management of the communication device 2.

[0026] Focusing on each of the communicators 2A, 2B, 2C, and 2D, in the illustrated example, communicator 2A is capable of 4G communication with 4G base station 121, communicator 2B is capable of 5G communication with 5G base stations 111A and 111B and 4G communication with 4G base station 121, and communicator 2C is capable of 5G communication with 5G base station 111C. In cases where there are multiple base stations (111A, 111B, 121) with which communicator 2B can communicate, one base station determined to be optimal in terms of communication quality, etc., is selected under the management of the 5G communication center (5GC) and / or the EPC core network, and communication with communicator 2B is performed. Furthermore, communicator 2D is not capable of communication with any of the 5G base stations 111 and 4G base station 121, and therefore performs communication via satellite communication system 13, which will be described next.

[0027] The satellite communication system 13 is a wireless communication system that uses a communication satellite 131, which is a low-orbit satellite flying in space at an altitude of approximately 500 km to 700 km above the Earth's surface, as a non-terrestrial base station. Similar to the 5G base station 111 and the 4G base station 121, the communication range or support area of ​​the communication satellite 131 is also called a cell and is illustrated as 132. In this way, the communication satellite 131, which is a non-terrestrial base station, provides the satellite communication cell 132, which is a non-terrestrial communication cell, to the ground. A terrestrial communication device 2 can perform satellite communication if it is located inside the satellite communication cell 132. Similar to the 5G base station 111 in the 5G wireless communication system 11 and the 4G base station 121 in the 4G wireless communication system 12, the communication satellite 131, which is a base station in the satellite communication system 13, can wirelessly communicate with the communication device 2 in the satellite communication cell 132 directly or indirectly via an aircraft or the like. The radio access technology that the communication satellite 131 uses for radio communication with the communication device 2 in the satellite communication cell 132 may be 5G NR, the same as the 5G base station 111, or LTE or LTE-Advanced, the same as the 4G base station 121, or any other radio access technology that can be used by the communication device 2. Therefore, the communication device 2 does not need to be provided with special functions or components for satellite communication.

[0028] The satellite communication system 13 includes a gateway 133 as a ground station installed on the ground and capable of communicating with a communication satellite 131. The gateway 133 includes a satellite antenna for communicating with the communication satellite 131, and is connected to a 5G base station 111 and a 4G base station 121 as terrestrial base stations constituting a terrestrial network (TN) via their respective wireless access technologies, such as 5G NR or LTE, or other wired or wireless access technologies or interfaces. In this way, the gateway 133 connects the non-terrestrial network (NTN) constituted by the communication satellite 131 as a non-terrestrial base station or satellite base station and the TN constituted by the terrestrial base stations 111 and 121 so that they can communicate with each other. When the communication satellite 131 performs 5G communication with the communication device 2 in the satellite communication cell 132 using 5G NR, the 5GC connected via the gateway 133 and the 5G base station 111 (or a 5G radio access network) in the TN is used as the core network, and when the communication satellite 131 performs 4G communication with the communication device 2 in the satellite communication cell 132 using LTE or LTE-Advanced, the EPC connected via the gateway 133 and the 4G base station 121 (or a 4G radio access network) in the TN is used as the core network. In this way, appropriate cooperation is achieved between different wireless communication systems such as 5G communication, 4G communication, and satellite communication via the gateway 133.

[0029] Satellite communication using a communication satellite 131 is primarily used to cover areas where terrestrial base stations such as 5G base station 111 and 4G base station 121 are not installed or are few in number. In the illustrated example, a communication device 2D located outside the communication cells of all terrestrial base stations communicates with the communication satellite 131. Meanwhile, communication devices 2A, 2B, and 2C that can communicate satisfactorily with any terrestrial base station are also within a satellite communication cell 132 and can therefore communicate with the communication satellite 131. However, by communicating with a terrestrial base station rather than the communication satellite 131 as a satellite base station, the limited communication resources (including power) of the communication satellite 131 are conserved for the communication device 2D and the like. The communication satellite 131 improves the quality of communication with the communication device 2D by directing communication radio waves toward the communication device 2D within the satellite communication cell 132 using beamforming.

[0030] The size of the satellite communication cell 132 of the communication satellite 131 serving as a satellite base station can be set arbitrarily depending on the number of beams emitted by the communication satellite 131; for example, a satellite communication cell 132 with a diameter of approximately 24 km can be formed by combining up to 2,800 beams. As shown in the figure, the satellite communication cell 132 is typically larger than a terrestrial communication cell such as the 5G cell 112 or the 4G cell 122, and may include one or more 5G cells 112 and / or 4G cells 122 therein. Note that, although the above example illustrates a communication satellite 131 flying in low orbit at an altitude of approximately 500 km to 700 km above the Earth's surface as a flying non-terrestrial base station, a communication satellite flying in high orbit such as a geostationary orbit, or an unmanned or manned aircraft or drone flying in the atmosphere at a lower altitude (for example, approximately 20 km above the Earth's surface) such as the stratosphere, may be used as a non-terrestrial base station in addition to or instead of the communication satellite 131.

[0031] FIG. 2 is a schematic functional block diagram of a wireless communication system 1 including a collected data transmission device 3 according to this embodiment. The collected data transmission device 3 includes a data collection unit 31, a collected data storage unit 32, a latest data aggregation unit 33, a collected data transmission unit 34, and a transmission success / failure determination unit 35. Some of these functional blocks may be omitted as long as the collected data transmission device 3 or the wireless communication system 1 can achieve at least some of the actions and / or effects described below. These functional blocks may be implemented by the cooperation of hardware resources, such as a central processing unit (CPU), memory, input devices, output devices, and peripheral devices connected to the computer, of a computer implemented in the collected data transmission device 3, and software executed using these hardware resources. Regardless of the type or location of the computer, each of the above functional blocks may be implemented by the hardware resources of a single computer or by combining hardware resources distributed across multiple computers.

[0032] For example, as described below, the data collection unit 31 may be configured with various sensors as hardware separate from the other functional blocks 32 to 35. Such a data collection unit 31 may be installed in a location remote from the hardware on which the other functional blocks 32 to 35 are implemented. In this case, the data collection unit 31 is connected to the collected data storage unit 32, etc., so as to be able to communicate with the collected data storage unit 32, etc. wirelessly or via a wire (at least in one direction from the data collection unit 31 to the collected data storage unit 32, etc.) in order to transmit the collected or measured data to the collected data storage unit 32, etc. In this way, the collected data transmission device 3 according to this embodiment may be configured with a combination of multiple hardware or devices configured to be able to communicate with each other. Note that the data collection unit 31 and the other functional blocks 32 to 35, etc. may be implemented in the collected data transmission device 3 as a single piece of hardware.

[0033] The collected data transmitting device 3 transmits collected data collected over time to a base station that provides a communication cell. In the example of FIG. 2, a communication satellite 131 as a non-terrestrial base station and a 4G base station 121 as a terrestrial base station are exemplified as base stations to which collected data is transmitted by the collected data transmitting device 3. Note that the satellite communication cell 132 as a non-terrestrial communication cell and the 4G cell 122 as a terrestrial communication cell that they respectively provide on the ground are not shown in the figure. However, the base station to which collected data is transmitted by the collected data transmitting device 3 is not limited to the communication satellite 131 or the 4G base station 121, and may be any type of base station exemplified in relation to FIG. 1.

[0034] 2 may transmit or provide the collected data to the server SV via either the communication satellite 131 or the 4G base station 121. In this way, the collected data transmitting device 3 may select any one of the base stations available to or communicable with it (which may be any one of the communication devices 2 connected thereto, as will be described later), and transmit or provide the collected data to the server SV via that base station.

[0035] The data collection unit 31 collects over time data (hereinafter also referred to as collected data or measured data) that the collected data transmitting device 3 transmits to base stations such as the communication satellite 131 and the 4G base station 121. The data collection unit 31 may be configured by various sensors that can measure various data at the installation location (i.e., can acquire measured data).

[0036] In this embodiment, the data collection unit 31 is configured with a soil sensor that measures temperature and humidity over time, which indicate the state of agricultural soil at the installation site. In addition to or instead of such a soil sensor, the data collection unit 31 may be equipped with a sensor or device that collects over time information about the environment, weather, and other conditions useful for agriculture, such as brightness, amount of sunlight, hours of sunlight, amount of rain, wind speed, atmospheric pressure, weather, crop growth status, and weed and pest infestation status at the installation site.

[0037] The data collection unit 31 may also be configured to acquire any measurement data over time according to the purpose of installation, not limited to agricultural support. For example, in the logistics field, the data collection unit 31 may be configured by various sensors attached to transport machinery such as trucks and ships that transport cargo, or to the cargo itself, capable of measuring various data over time, such as temperature, humidity, brightness, vibration, and position based on a GPS (Global Positioning System). Furthermore, the data collection unit 31 or the collected data transmission device 3 according to this embodiment can be used not only in agriculture and logistics, but also in any other applications, such as smart cities, environmental monitoring, and energy management.

[0038] The collected data holding unit 32 at least temporarily holds the collected data or measurement data collected over time by the data collecting unit 31 before the collected data transmitting unit 34 transmits the data to a base station such as the communication satellite 131 or the 4G base station 121. The collected data holding unit 32 may be configured with a storage medium such as a memory or storage device with limited capacity. As will be described in detail later, the collected data holding unit 32 generally operates on a FIFO (First In, First Out) basis, and when new collected data is written to the collected data holding unit 32 that has substantially no free space, the oldest collected data is overwritten or erased in order.

[0039] The data collection unit 31 as various sensors and the collected data storage unit 32 that stores the measurement data may be implemented as different hardware. In this case, the data collection unit 31 and the collected data storage unit 32 (or the main body of the collected data transmission device 3) are connected wirelessly or with a wire so that collected data can be transmitted from at least the data collection unit 31 to the collected data storage unit 32. For example, the data collection unit 31 and the collected data storage unit 32 may be connected to each other so that communication can be performed unidirectionally (from the data collection unit 31 to the collected data storage unit 32) or bidirectionally using a wireless communication method that preferably has low power consumption, such as LoRa. Since LoRa enables long-distance transmission of, for example, 2 km to 15 km, the data collection unit 31 as a soil sensor or the like and the main body of the collected data transmission device 3 including the collected data storage unit 32 can be installed in different locations that are far apart.

[0040] The collected data collected by the data collection unit 31 and at least temporarily stored by the collected data storage unit 32 can be classified according to its collection period. As shown in Fig. 2, the collected data stored by the collected data storage unit 32 includes the latest data collected in the latest collection period (conveniently indicated as N (natural number)), past data collected in the collection period just before that (conveniently indicated as N-1), past data collected in the collection period just before that (conveniently indicated as N-2), etc.

[0041] As mentioned above, the capacity of the collected data storage unit 32 is limited, so in principle, collected data is overwritten or deleted in order, starting with the oldest. For example, if the collected data storage unit 32 can store collected data for a maximum of M (a natural number) collection periods, collected data from M collection periods (NM) before the most recent collection period is sequentially deleted. Specifically, when new, latest data (collection period N+1) is stored in the collected data storage unit 32, the oldest past data (collection period N-M+1) is deleted at that time. Furthermore, the latest data from the previous collection period (collection period N) becomes past data for the new, latest data (collection period N+1).

[0042] The lengths of the M collection periods for which collected data is stored in the collected data storage unit 32 may be equal to or different from one another. In this embodiment, all of the M collection periods have a uniform length of one day (24 hours). In this case, the collected data storage unit 32 stores collected data for M consecutive days (with substantially no overlapping).

[0043] Note that consecutive collection periods that are statically set as described above may overlap in time.

[0044] FIG. 3 shows an example of data collected over time when the data collection unit 31 is a soil sensor.

[0045] 3A is a graph of RSSI (Received Signal Strength Indicator), which may constitute part of collected data over time. This RSSI indicates the signal strength of collected data received by the collected data storage unit 32 or the main body of the collected data transmission device 3 from the data collection unit 31 (a soil sensor) via wireless communication such as LoRa. In the example of FIG. 3A, RSSI for eight days from July 25 to August 1 is shown.

[0046] 3B is a graph of the voltage of the collected data transmitting device 3 (excluding the data collecting unit 31) which may constitute part of the collected data over time. This voltage is measured by a voltage sensor (not shown) mounted on the collected data transmitting device 3 (excluding the data collecting unit 31) which functions as a data collecting unit separate from the soil sensor 31. In the example of FIG. 3B, as in FIG. 3A, the voltage for eight days from July 25th to August 1st is shown.

[0047] FIG. 3C is a graph of measurement data by the soil sensor 31 that may constitute part of the data collected over time. In this embodiment, the soil sensor 31 measures two types of data: soil temperature and humidity. The two graphs shown in FIG. 3C show the changes in temperature and humidity over time, respectively. In the example of FIG. 3C, similar to FIGS. 3A and 3B, the temperature and humidity for eight days from July 25 to August 1 are shown.

[0048] In Figure 2, the latest data aggregation unit 33 aggregates the latest data collected during the latest collection period (in the example of Figure 2, N, which is the latest day (24 hours)) from the collected data collected by the data collection unit 31 or held by the collected data holding unit 32 into priority transmission data PD that is equal to or smaller than the size that can be transmitted in one go by the collected data transmission unit 34.

[0049] The size of data that can be transmitted at one time by the collected data transmitting device 3 or the collected data transmitting unit 34 may be expressed as 1 MTU (Maximum Transmission Unit). The size of 1 MTU is determined by a communication method (e.g., RAT) with a base station (the communication satellite 131 or the 4G base station 121 in the example of FIG. 2) or the communication device 2 to which the collected data is to be transmitted. For example, 1 MTU is approximately 1,400 bytes when the collected data transmitting unit 34 transmits collected data to the communication satellite 131, the 4G base station 121, the 5G base station 111 (not shown), or the like by LTE. Furthermore, 1 MTU when the collected data transmitting unit 34 transmits collected data to the communication satellite 131 or the 5G base station 111 (not shown) by 5G NR, or 1 MTU when the collected data transmitting unit 34 transmits collected data to the communication device 2 by Wi-Fi (registered trademark), for example, may differ from 1 MTU in the case of LTE.

[0050] In this embodiment, the specific size (or value) of one MTU is not important, but in this example embodiment where the length of each collection period is one day (24 hours), the size of the collected data collected in each collection period (i.e., each day) (in the example of FIG. 3, a set of 24 hours' worth of RSSI, 24 hours' worth of voltage of the collected data transmitting device 3, and 24 hours' worth of temperature and humidity measurements by the soil sensor 31) is much larger than one MTU. In the case of LTE transmission, one MTU is 1400 bytes, while the collected data in each collection period (i.e., each day) is, for example, approximately 400 kilobytes.

[0051] When the collected data transmission unit 34 (strictly speaking, the normal transmission unit 342 described later) transmits the collected data for each collection period that exceeds 1 MTU (by a large margin) in this way essentially as is (although data compression, etc., may be performed), the collected data needs to be divided into many (multiple) packets of 1 MTU or less and transmitted multiple times (multiple times). In addition to or instead of such multiple normal transmissions, the latest data aggregation unit 33 aggregates the latest data (N) of up to approximately 400 kilobytes into prioritized transmission data PD of 1 MTU or less (for example, 1,400 bytes in the case of LTE communication) to enable prioritized transmission that can be completed in one go by the priority transmission unit 341 described later.

[0052] As long as the latest data (N) can be aggregated or compressed into prioritized transmission data PD of 1 MTU or less, any mode or method of aggregation may be used by the latest data aggregation unit 33. For example, the latest data aggregation unit 33 may aggregate the latest data collected in the latest collection period (N) into statistics over the latest collection period (i.e., the most recent day (24 hours)).

[0053] 3, the latest data aggregator 33 may aggregate each piece of time-series measurement data (FIG. 3C) of temperature and humidity over the most recent day (24 hours) by the soil sensor 31 into any statistical value such as maximum, minimum, mean, median, mode, standard deviation, variance, range, skewness, or kurtosis that can be calculated based on each piece of measurement data for that day. In this way, by aggregating a large amount of measurement data (for the most recent day) as exemplified in FIG. 3C into a small number of statistical values, the latest data aggregator 33 can generate prioritized transmission data PD of 1 MTU or less.

[0054] However, the latest data aggregator 33 may aggregate the latest data (N) into prioritized transmission data PD of 1 MTU or less using a non-statistical method. For example, the latest data aggregator 33 may generate prioritized transmission data PD of 1 MTU or less by sampling a small number of measurement data from the temperature and humidity measurement data (FIG. 3C) over the most recent day (24 hours) measured by the soil sensor 31. In this case, the sampling period may be fixed (e.g., 1 hour) or variable. If the sampling period is variable, it is preferable that the latest data aggregator 33 autonomously increase the sampling period during periods of interest in the measurement data, such as periods when the measurement data values ​​are large or small, periods when the measurement data change significantly, or periods when abnormal behavior of the measurement data is observed. In addition to or instead of the above, the latest data aggregator 33 may incorporate the most recent or most recent instantaneous values ​​of the temperature and humidity measurement data measured by the soil sensor 31 into the prioritized transmission data PD.

[0055] As described above, when the latest data aggregator 33 aggregates data into the prioritized transmission data PD, it is preferable that measurement data (FIG. 3C) from the data collector (soil sensor) 31, which is considered to be of high importance, be preferentially incorporated into the prioritized transmission data PD. Meanwhile, collected data (hereinafter also referred to as device status data) indicating the status or operating status of the collected data transmitting device 3 itself, such as the RSSI shown in FIG. 3A or the voltage of the collected data transmitting device 3 shown in FIG. 3B, may also be incorporated into the prioritized transmission data PD as long as it satisfies the condition of 1 MTU or less. Like the measurement data, the device status data may be aggregated into prioritized transmission data PD of 1 MTU or less using a statistical or non-statistical method. Alternatively, the device status data (FIGS. 3A and 3B) may not be incorporated into the prioritized transmission data PD at all because it is less important than the measurement data (FIG. 3C).

[0056] In either case, it is preferable to make the ratio of device status data in the priority transmission data PD ("size of device status data included in priority transmission data PD" ÷ "size of measurement data included in priority transmission data PD") smaller than the ratio of device status data in the latest data (N) before aggregation by the latest data aggregation unit 33 ("size of device status data included in latest data" ÷ "size of measurement data included in latest data").

[0057] In this embodiment, as priority transmission data PD of 1 MTU or less (1,400 bytes in the case of LTE transmission), the latest data aggregation unit 33 generates the maximum and minimum values ​​(specifically, the maximum temperature value in the last 24 hours, the minimum temperature value in the last 24 hours, the maximum humidity value in the last 24 hours, and the minimum humidity value in the last 24 hours) and the latest or most recent instantaneous values ​​of the temperature and humidity measurement data for the most recent day (24 hours) taken by the soil sensor 31 shown in Figure 3C, as well as the RSSI shown in Figure 3A and the latest or most recent instantaneous value of the voltage of the collected data transmission device 3 (i.e., device status data) shown in Figure 3B.

[0058] The collected data transmitting unit 34 includes a priority transmitting unit 341 that transmits, with the highest priority, prioritized transmission data PD of 1 MTU or less that has been aggregated by the latest data aggregating unit 33, and a normal transmitting unit 342 that, after the priority transmission of the priority transmission data PD by the priority transmitting unit 341, divides into a large number of packets and sequentially transmits normal collected data (however, the size may be reduced by data compression, etc.) for each collection period that exceeds 1 MTU (by a large margin) and that has not been aggregated by the latest data aggregating unit 33. Note that the priority transmitting unit 341 and the normal transmitting unit 342 (i.e., the entire collected data transmitting unit 34) are preferably configured as a single transmitting unit or transmitter in terms of hardware.

[0059] 2, the collected data transmission unit 34 transmits collected data (including prioritized transmission data PD) to a base station such as a communication satellite 131 or a 4G base station 121. The collected data transmission unit 34 may be directly connected to the communication satellite 131 (represented by a solid line) within a satellite communication cell 132 (not shown) provided by the communication satellite 131, and may transmit the collected data directly to the communication satellite 131 using any RAT such as 5G NR or LTE. Furthermore, the collected data transmission unit 34 may be directly connected to the 4G base station 121 (represented by a solid line) within a 4G cell 122 (not shown) provided by the 4G base station 121, and may transmit the collected data directly to the 4G base station 121 using any RAT such as LTE.

[0060] In the example of FIG. 2 , the collected data transmission unit 34 may indirectly transmit the collected data to a base station (the communication satellite 131 or the 4G base station 121) via a communication device 2 located within a communication cell (the satellite communication cell 132 provided by the communication satellite 131 or the 4G cell 122 provided by the 4G base station 121). In this case, the collected data transmission unit 34 transmits the collected data to the communication device 2, such as a smartphone, tablet, or personal computer, using any wireless or wired communication protocol, such as Wi-Fi (registered trademark) (represented by a dotted line). Then, the communication device 2 is directly connected (represented by a dotted line) to the base station (the communication satellite 131 or the 4G base station 121) within the communication cell (the satellite communication cell 132 or the 4G cell 122), and transmits or transfers the collected data (received from the collected data transmission unit 34) directly to the base station using any RAT, such as 5G NR or LTE.

[0061] The collected data received by the communication satellite 131 directly or indirectly from the collected data transmission unit 34 is transferred to the core network CN via a base station or radio access network (RAN) such as the gateway 133 or 5G base station 111 that can communicate with the communication satellite 131, as described above with reference to Fig. 1. Also, the collected data received by the 4G base station 121 directly or indirectly from the collected data transmission unit 34 is transferred to the core network CN, as described above with reference to Fig. 1.

[0062] The core network CN collects collected data (including device status data) such as measurement data and device status data collected by the data collection unit 31 or the collected data transmission device 3, and transfers the collected data transferred from a base station, etc. to a server SV that provides any service for monitoring, analysis, etc.

[0063] As described above, the acknowledgement (ACK) of the collected data transmitted from the collected data transmitter 34 can be returned from any entity on the transmission path to the collected data transmitter 34 or to an entity preceding the entity (on the collected data transmitter 34 side). In the example of Fig. 2, at least one of the communication satellite 131, 4G base station 121, communication device 2, gateway 133, core network CN, server SV, etc., through which the collected data from the collected data transmitter 34 may pass or arrive, returns an acknowledgement of the collected data to the collected data transmitter 34.

[0064] The transmission success / failure determination unit 35 determines whether the transmission of the collected data (including the prioritized transmission data PD) by the collected data transmission unit 34 has been successful or not, depending on the response from the base station (communication satellite 131 or 4G base station 121), the communication device 2, etc. to the transmission of the collected data (including the prioritized transmission data PD). Specifically, the transmission success / failure determination unit 35 determines that the transmission of the collected data has been successful if it receives a receipt confirmation from the base station (communication satellite 131 or 4G base station 121), the communication device 2, etc. within a predetermined period after the transmission, and determines that the transmission of the collected data has failed if it does not receive a receipt confirmation from the base station (communication satellite 131 or 4G base station 121), the communication device 2, etc. within the predetermined period after the transmission.

[0065] The collected data transmitting unit 34 transmits priority transmission data PD of 1 MTU or less as a top priority by the priority transmitting unit 341, and if the transmission success / failure determining unit 35 determines that the transmission is successful, the normal collected data of each collection period that (much) exceeds 1 MTU is divided into a large number of packets and transmitted sequentially by the normal transmitting unit 342, starting from the most recent collection period.

[0066] In other words, as shown schematically in FIG. 2, when transmitting collected data, the collected data transmission unit 34 sets the highest first priority to the prioritized transmission data PD of 1 MTU or less aggregated by the latest data aggregation unit 33, sets the next highest second priority to the latest data (before being aggregated by the latest data aggregation unit 33) relating to the latest collection period (N), sets the next highest third priority to the past data relating to the collection period one period before that (N-1), and sets the next highest fourth priority to the past data relating to the collection period one period before that (N-2) (and so on up to collection period (N-M+1)).

[0067] In particular, the priority transmission unit 341 transmits the latest data (priority transmission data PD of 1 MTU or less) aggregated by the latest data aggregation unit 33 with the highest priority (first priority) to the base station (communication satellite 131 or 4G base station 121) or the communication device 2. The transmission success / failure determination unit 35, which serves as a priority transmission success / failure determination unit, determines the success or failure of the priority transmission according to the response (for example, presence or absence of reception confirmation) from the base station (communication satellite 131 or 4G base station 121) or the communication device 2, etc., to the priority transmission of the priority transmission data PD of 1 MTU or less by the priority transmission unit 341.

[0068] When the transmission success / failure determination unit 35 determines that the priority transmission by the priority transmission unit 341 was successful based on receiving a reception confirmation from the base station, the communication device 2, or the like, the normal transmission unit 342 sequentially transmits the untransmitted collected data (data not yet aggregated by the latest data aggregation unit 33) in accordance with the above priority. In the example of FIG. 2, the normal transmission unit 342 transmits the latest data (data before being aggregated by the latest data aggregation unit 33) relating to the latest collection period (N), the past data relating to the collection period immediately before that (N-1), and the past data relating to the collection period immediately before that (N-2) in that order. As described above, since the size of the collected data relating to each collection period exceeds 1 MTU, the normal transmission unit 342 divides the collected data relating to each collection period into multiple packets and transmits them to the base station, etc., multiple times.

[0069] On the other hand, if the transmission success / failure determination unit 35 determines that the priority transmission by the priority transmission unit 341 has failed based on not receiving a receipt confirmation from the base station, the communication device 2, etc. within a predetermined period of time, the priority transmission unit 341 and the normal transmission unit 342 suspend the transmission of collected data (retransmission of the failed priority transmission data PD or transmission of unaggregated collected data) for at least a predetermined period of time (or reduce the transmission frequency for at least a predetermined period of time). In this way, if the priority transmission of priority transmission data PD of 1 MTU or less has failed, it is considered that data transmission from the collected data transmission unit 34 to the server SV is substantially impossible, so it is preferable to temporarily suspend the transmission of collected data (including retransmission of the priority transmission data PD), which is likely to waste resources such as limited power of the collected data transmission device 3, and wait for the connection on the transmission path to be restored.

[0070] It is also possible that the transmission success / failure determination unit 35 determines that the normal transmission by the normal transmission unit 342 failed after the priority transmission by the priority transmission unit 341 was successful. For example, satellite communication via the communication satellite 131 does not always provide stable communication like terrestrial base stations, and operation in a degenerate state is also expected. In such a case, small-sized data such as prioritized transmission data PD of 1 MTU or less can be transmitted, but large-sized data such as collected data related to each collection period that has not yet been aggregated cannot be transmitted. In this way, if the transmission success / failure determination unit 35 determines that the normal transmission by the normal transmission unit 342 failed based on not receiving a reception confirmation from the base station, communication device 2, etc. within a predetermined period, it is preferable that the normal transmission unit 342 suspends subsequent transmission of collected data (retransmission of the failed collected data and transmission of past data related to the previous collection period) for at least a predetermined period.

[0071] As described above, according to this embodiment, the possibility of transmitting subsequent collected data can be dynamically determined depending on the success or failure of the priority transmission of the priority transmission data PD and the normal transmission of unaggregated collected data. Furthermore, even if the normal transmission of unaggregated collected data fails, there is a possibility that prioritized communication of the priority transmission data PD of 1 MTU or less will be successful. As described above, the priority transmission data PD aggregates statistical values ​​of highly important measurement data, so if the wired communication is successful, a minimum amount of information can be provided to the server SV. Then, after waiting for the transmission path to be restored to a state where normal transmission of unaggregated collected data is possible, the raw (unaggregated) collected data that served as the basis for the transmitted statistical values ​​can be replenished to the server SV.

[0072] Figure 4 shows a schematic diagram of the change over time in the measurement data (temperature and humidity) of the soil sensor 31 received by the server SV when the transmission path is restored after a period in which the collected data transmission unit 34 was unable to transmit collected data.

[0073] In Fig. 4A, due to a communication failure or connection problem that occurred on August 1st, the collected data transmission unit 34 was unable to transmit collected data for approximately 24 hours. During this period, the priority transmission unit 341 was also unable to transmit prioritized transmission data PD of 1 MTU or less, and so measurement data was completely missing (shown by dotted lines for convenience). This untransmitted or untransmittable collected data is held in the collected data holding unit 32 in Fig. 2 until it becomes transmittable.

[0074] FIG. 4B shows an example in which, for example, the communication failure or connection failure that occurred in FIG. 4A has continued for about 24 hours, but only 1 MTU of collected data has been transmitted. In response to this, the collected data transmission unit 34 transmits the highest priority transmission data PD to the server SV by the priority transmission unit 341. As described above, in this embodiment, the priority transmission data PD contains the instantaneous values ​​of the measurement data (temperature and humidity) by the soil sensor 31, the maximum value over the last 24 hours, and the minimum value over the last 24 hours. Therefore, as shown in FIG. 4B, the server SV receives the instantaneous value Tins , the maximum value in the last 24 hours T max , the minimum value T in the last 24 hours min , the instantaneous humidity value M ins , maximum value in the last 24 hours M max , minimum value M in the last 24 hours min A total of six measurement data points are received. These minimum measurement data partially compensate for the missing measurement data in Figure 4A and visualize the overall trend.

[0075] 4B, the collected data transmission unit 34 normally transmits the latest data (before being aggregated by the latest data aggregation unit 33) relating to the latest collection period (N) with the second highest priority to the server SV via the normal transmission unit 342. If this normal transmission is successful, the missing measurement data in FIG. 4A is completely compensated for, as shown in FIG. 3C.

[0076] According to the above-described embodiment, the state and capacity of the transmission path to the server SV can be confirmed by the priority transmission of the priority transmission data PD of 1 MTU or less and the subsequent normal transmission, and if the transmission fails, subsequent unnecessary transmissions can be at least temporarily stopped. In particular, the priority transmission data PD of 1 MTU or less has the function of delivering measurement data, etc., aggregated by the latest data aggregation unit 33 to the server SV, as well as the function of confirming whether the transmission path to the server SV is in a state where data of the minimum size of 1 MTU can be transmitted. Note that, prior to the priority transmission of the priority transmission data PD of 1 MTU or less, the priority transmission unit 341 or the collected data transmission unit 34 may send a confirmation message or test message (preferably also 1 MTU or less) to confirm the state of the transmission path to the server SV, and may transmit the priority transmission data PD upon receiving confirmation of the reception of the message.

[0077] In FIG. 2, the priority transmission data PD that has been sent (and preferably has received confirmation of receipt) by the collected data sending unit 34 and the collected data relating to each collection period may, in principle, be deleted in order starting with the oldest, or may be retained as a backup for at least a certain period of time as long as there is available capacity in the collected data retention unit 32.
