Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in information and communication systems such as LTE (Long Term Evolution), 4G (4th Generation), and 5G (5th Generation), the core network provides sensing services. The internal configuration of the workspace, the configuration of the core network, and the interfaces with external systems outside the core network were not clearly defined.

[0006] One aspect of the disclosed embodiment is to enable the efficient provision of sensing-based information in information and communication systems. [Means for solving the problem]

[0007] Embodiments of the disclosure are illustrated by an information and communication system. This information and communication system is an information and communication system that responds with information related to a target to be detected in response to a request from a requester. This information and communication system includes a control unit that receives the frequency at which the information is to be responded to and responds with the information based on the received frequency. [Effects of the Invention]

[0008] This information and communication system can efficiently provide information through sensing. [Brief explanation of the drawing]

[0009] [Figure 1] Figure 1 shows the components (parts) that make up the fifth-generation mobile communication system. [Figure 2] Figure 2 illustrates the configuration of a data center forming a 5GC. [Figure 3] Figure 3 is an explanatory diagram of the information processing system according to the embodiment. [Figure 4] Figure 4 shows an example of the configuration of an information processing device. [Figure 5] Figure 5 shows an example of a terminal configuration. [Figure 6] Figure 6 is a sequence diagram showing an example of processing sensing information in this information and communication system. [Figure 7] Figure 7 is a flowchart illustrating the process when SENSING notifies the NEF of information that satisfies the sensing conditions. [Figure 8] Figure 8 is a flowchart illustrating the processing of the receiver. [Figure 9] Figure 9 illustrates the processing of NEF and SENSING. [Figure 10] Figure 10 is a flowchart illustrating the SENSING process using a modified example. [Modes for carrying out the invention]

[0010] The information communication system, control device, and information communication method of this embodiment will be described below with reference to the drawings. This information communication system responds with information related to the target to be detected in response to a request from the requester. This information communication system includes a control unit that receives the frequency at which information should be responded to and responds with information based on the received frequency. The frequency is also called the response rate.

[0011] This information and communication system is based on standards for 5G systems and later. The requester may be a device, UE, server, etc., on another network outside of this information and communication system. Furthermore, the requester may be one of the components called NF or AF within this information and communication system. The control unit of this information and communication system then provides a standard-based sensing service to the information requester (also called a receiver).

[0012] In this information communication system, the control unit receives from the requester the detection conditions for detecting information and different detection frequencies corresponding to those conditions. In other words, a feature of this information communication system is that it accepts different detection frequencies when it detects information. These detection conditions may include at least one of the following: whether or not the object to be detected is moving, its speed of movement, its size, the history of the information in the object to be detected, the area in which the object to be detected is located, the location of the object to be detected, and the required level of confidence for the information.

[0013] This information communication system further includes a detection unit that detects information related to a detection target, and the roles may be shared with the control unit. For example, the control unit reserves the detection by specifying the detection frequency and detection conditions to the detection unit. Here, the term "reservation" is based on Subscribe. On the other hand, the detection unit notifies the control unit of the information that satisfies the detection conditions, and the control unit may further notify the information notified from the detection unit to the requester. Also, the detection unit may change the detection frequency according to the detected information. The detection unit may obtain the information acquired or generated in the device connected to the information communication system or the device connected to another network connected to the information communication system and notify the control unit.

[0014] The control unit accepts a plurality of detection conditions specified by the identification information, and each detection condition is associated with a selection condition. The control unit may select the detection condition that satisfies the selection condition and select the information related to the detection target. Note that the detected information is dynamic information when the object related to the geographical information changes over time, and is effective for creating or updating the dynamic map. In the following embodiments, the detection condition is called a sensing condition.

[0015] (Embodiment 1) Hereinafter, embodiments of the present disclosure will be described based on the drawings. The following embodiments are merely examples for explanation, and the present disclosure is not limited to the configurations of the embodiments. For example, hereinafter, an example in which the present disclosure is applied to the fifth-generation mobile communication system will be described, but the present disclosure may be applied to the fourth-generation or subsequent fifth-generation mobile communication systems. The present disclosure is also by other than 3GPP It may be applied to a mobile communication system defined by this, or may be applied to any wireless communication system or wired communication system other than the mobile communication system. Also, as information used by a receiver exemplified by an external application server, sensing information detected, measured, or generated by an external device connected to a fifth-generation mobile communication system is exemplified. However, the information provided and used may be sensing information measured by other than an external device connected to the fifth-generation mobile communication system, or may be any data other than the sensing information. For example, the receiver may be provided with and use information obtained by a component called a Network Function (NF) in the fifth-generation mobile communication system. Also, the receiver may be provided with and use information obtained by a component called an Aplicatin Function (AF).

[0016] <Configuration of Information Processing System> FIG. 1 shows components (constituent elements) constituting a fifth-generation mobile communication system (also called 5G network, 5GNW). In FIG. 1, UE (User Equipment) 2 is a terminal of a user (subscriber). RAN (Radio Access Network) 3 is an access network to a 5G core network (5GC). RAN 3 is constituted by a base station (gNB) 3A. The 5G network has a 5G core network (5GC) and an access network ((R)AN), and the UE 2, DN 5, and AF 12 are connected to the 5G network. Each of NF11a to 11k, 11n is a function realized by one or more computers (information processing devices) executing a program. However, a single computer may realize any two or more of NF11a to 11k. In this embodiment, the components of 5GC are collectively called NF11 and individually called NEF11e and the like. In FIG. 1, each component is assigned an individual code in parentheses together with a general code.

[0017] As described above, 5GC is composed of a set of components that have predetermined functions called NFs (Network Functions). Figure 1 illustrates the following as NF11 that make up 5GC. In Figure 1, they are shown as rectangles with thick lines. UPF (User Plane Function) 11a AMF (Access and Mobility Management Function)11b SMF (Session Management Function)11c PCF(Policy Control Function)11d NEF(Network Exposure Function)11e NRF(Network Repository Function)11g NSSF(Network Slice Selection Function)11h AUSF(Authentication Server Function)11i UDM(Unified Data Management)11j NWDAF(Network Data Analytics Function)11k UPF11a handles routing and forwarding of user packets (user plane packets sent and received by UE2), packet inspection, and QoS processing. AMF11b is the UE location accommodation device in 5GC1 (Figure 3). AMF11b accommodates RAN3 and performs subscriber authentication control, UE2 location (mobility) management, etc. UDM11j provides subscriber information, or retrieves, registers, deletes, and modifies the status of UE2.

[0018] SMF11c manages PDU (Protocol Data Unit) sessions and controls UPF11a for QoS (Quality of Service) control and policy control. A PDU session is a virtual communication channel for data exchange between UE2 and DN (Data Network) 5. DN5 is an external data network (such as the Internet) outside of 5GC.

[0019] PCF11d performs QoS control, policy control, and billing control under the control of SMF11c. QoS control involves controlling the quality of communication, such as prioritizing packet forwarding. Policy control involves communication control such as QoS, packet forwarding eligibility, and billing based on network or subscriber information. NEF11e uses AF (Application Function)12, and It plays the role of mediating communication between nodes outside 5GC and 3GPP's NF. AF12 is an element that interacts with 5GC to provide services to the user. In this embodiment, AF12 requests and receives sensing information provided by SENSING11n. Therefore, in this embodiment, AF12 is referred to as a sensing information receiver (hereinafter simply referred to as a receiver).

[0020] NRF11g stores and manages information on NFs (e.g., AMF, SMF, UPF, etc.) within 5GC1 (Figure 3). In response to an inquiry regarding an NF that the user wishes to use, NRF11g can return multiple candidate NFs to the inquirer.

[0021] NSSF11h has the function of selecting the network slice to be used by the subscriber from among the network slices generated by network slicing. A network slice is a virtual network with specifications tailored to its intended use.

[0022] AUSF11i is a subscriber authentication server that performs subscriber authentication under the control of AMF11b. UDM11j holds subscriber-related information. NWDAF11k has the function of collecting and analyzing data from each NF11, OAM terminal 8 (Figure 2), receiver 12a (Figure 3), etc. In other words, NWDAF11k is an NF that provides network analysis information.

[0023] SENSING11n performs sensing processing, which includes collecting sensing information from UE2 or other external systems, and providing the collected sensing information to UE2, AF12, or other external systems (such as DN5). Details of SENSING11n will be described later.

[0024] Figure 2 illustrates the configuration of data centers 6 that form 5GC. Each NF forming 5GC consists of one or more information processing devices (servers and network equipment, etc.). The information processing devices are installed in a special building called a data center. A data center is also called a central office. As shown in Figure 2, one or more data centers 6 are located within the communication area of ​​5GC (three are shown as an example in Figure 2), and the data centers 6 are connected by communication lines 7. Each data center 6 is equipped with an OAM (Operations, Administration, and Maintenance) terminal 8. The OAM terminal 8 has the function of operating, managing, and maintaining the network (5GC).

[0025] In 5GC, multiple NFs of the same type may be provided. For example, NF11 may be provided for each data center 6. Also, one NF11 may be shared among data centers 6. Furthermore, one data center 6 may comprise multiple NF11s of the same type. The number of data centers 6, the number of NF11s, and the correspondence between NF11 and data centers 6 can be set as appropriate.

[0026] Figure 3 is an explanatory diagram of an information processing system according to an embodiment. The 5GC1 shown in Figure 3 has NF11 (11a~11k, 11n) as shown in Figure 1A. UE2 wirelessly connects to base station 3A which constitutes RAN3 and can exchange data with a communication partner (DN5) through 5GC1. In the example shown in Figure 3, UE2 is mounted on vehicle 9, but UE2 does not have to be an in-vehicle terminal. UE2 may be a mobile terminal or a smartphone. Vehicle 9 may be a human-driven vehicle or an autonomous vehicle. good.

[0027] SENSING11n receives a request for sensing information from, for example, receiver 12a via NEF11e, and collects sensing information from the specified detection target. It then notifies receiver 12a, which received the request for sensing information, of the collected sensing information via NEF11e. Receiver 12a includes UE2 connected to 5GC, other network devices connected to 5GC, information processing devices, servers, etc., as well as base station 3A and NF11. Note that NF11 requesting sensing information can also be referred to as the requesting NF11 or NF11 as receiver 12a.

[0028] In the following embodiment, the process will be explained using an external device 13 as an example of the detection target. Therefore, in this embodiment, the external device 13 may include a UE2 connected to 5GC, other network devices connected to 5GC, an information processing device, a server, etc. Also, the external device 13 may include NF11 other than the requesting NF11 mentioned above. The external device 13 monitors the detection target with sensors, etc., according to the sensing conditions (also called detection conditions) specified by SENSING11n, acquires information from the detection target, and reports (notifies or responds) to SENSING11n.

[0029] In this embodiment, the information monitored and acquired by the external device 13 can be described as dynamic information, such as when objects related to geographical information change over time. When the receiver 12a receives notification of dynamic information from this information communication system, the receiver 12a can efficiently create a dynamic map. A dynamic map is defined as high-precision three-dimensional geospatial information (basic map information) that allows the vehicle's position on the road and its surroundings to be identified at the lane level, and on top of that, various additional map information necessary to support autonomous driving, etc. (for example, traffic regulation information including dynamic information such as accidents and construction information, in addition to static information such as speed limits) (Public-Private ITS Concept and Roadmap 2016, Headquarters for the Promotion of an Advanced Information and Communications Network Society, May 20, 2016 https: / / www8.cao.go.jp / cstp / gaiyo / sip / iinkai / jidousoukou_23 / sanko3.pdf, accessed May 13, 2023). However, the processing of the receiver 12a in this embodiment is not limited to updating the dynamic map.

[0030] There are no limitations on the detection targets monitored by the external device 13 or the sensors used for monitoring. Sensors can detect, for example, images including video and still images, sounds including audio, temperature, humidity, wind speed, precipitation, pressure, mass, and physical quantities detected by vehicles. Sensors that detect images include cameras, which acquire images from a predetermined area, environment (roads, rivers), objects, etc. Cameras can also be mounted on moving objects (vehicles, ships, aircraft, satellites, etc.) and acquire images while in motion. The images acquired by the external device 13 can usually be described as dynamic information of the target object as it changes over time.

[0031] The sound sensor is a microphone that collects sound from the environment in which it is installed or from the surroundings of the mobile object on which it is mounted. Sensors that detect temperature, humidity, wind speed, precipitation, pressure, mass, etc., are measuring devices that measure the respective physical quantities. Physical quantities detected in a vehicle include, for example, speed, acceleration, angular velocity, direction of movement, direction of acceleration, direction of rotation, engine speed, fuel or battery level, voltage and current values ​​of power circuits, resistance values, and the current location of the mobile object. The sound and other physical quantities acquired by the external device 13 can be considered dynamic information as the object changes over time.

[0032] However, the sensor may simply be the control unit of the computer itself. For example, the sensing information acquired by the control unit of the computer acting as a sensor may include values ​​calculated by a computer as exemplified in a simulator, parameters set in manufacturing equipment in a manufacturing process, etc. This includes store sales and inventory for a specified period, the number of units sold for each product during a specified period, and the number of users and sales of services provided during a specified period. This sensing information can be considered dynamic information as the target object changes over time.

[0033] Sensing services using SENSING11n can be provided using either the Subscribe / Notify method or the Request / Response method (similar to the provisions of TS23.288 Chapter 6.1, TS38.502 Chapter 4.15.3, etc.).

[0034] <Configuration of information processing equipment and terminal> Figure 4 shows an example configuration of an information processing device 20 that can operate as NF11a~11k, 11n, OAM terminal 8, and receiver 12a, respectively. In Figure 4, the information processing device 20 can be configured using a dedicated or general-purpose information processing device (computer) such as a personal computer (PC), workstation (WS), or server machine. However, the information processing device 20 may also be a collection of one or more computers (cloud).

[0035] The information processing device 20 includes a processor 21 acting as a processing unit or control unit (controller), a storage device 22, a communication interface 23 (communication IF 23), an input device 24, and a display 25, all interconnected via a bus 26.

[0036] The storage device 22 includes main memory and auxiliary storage. The main memory is used as at least one of the following: a program and data storage area, a program deployment area, a program work area, and a communication data buffer area. The main memory consists of RAM (Random Access Memory), or a combination of RAM and ROM (Read Only Memory). The auxiliary storage is used as a data and program storage area. Non-volatile storage media are used for the auxiliary storage. Non-volatile storage media include, for example, hard disks, solid state drives (SSDs), flash memory, or EEPROM (Electrically Erasable Programmable Read-Only Memory). The storage device 22 may also include a drive device for a disk recording medium.

[0037] Communication IF23 is a circuit that performs communication processing. For example, communication IF23 is a network interface card (NIC). Alternatively, communication IF23 may be a wireless communication circuit that performs wireless communication (such as 5G, wireless LAN (Wi-Fi®), BLE, etc.). Furthermore, the communication IF23 may be a combination of a circuit that processes wired communication and a wireless communication circuit.

[0038] The input device 24 includes keys, buttons, pointing devices, and touch panels, and is used for inputting information. The display 25 is, for example, a liquid crystal display and displays information and data.

[0039] The processor 21 performs various processes by executing various programs stored in the storage device 22. By the processor 21 executing the programs stored in the storage device 22, the information processing device 20 can operate as NF11a~11k, 11n, OAM terminal 8, and receiver 12a, respectively.

[0040] Figure 5 shows an example configuration of a terminal 40 that can operate as a UE2. The terminal 40 includes a processor 41, a storage device 42, a communication interface 43 (communication IF 43), an input device 44, and a display 45, all interconnected via a bus 46. The processor 41, storage device 42, communication IF 43, input device 44, and display 45 are the same as those of the processor 21, storage device 22, communication IF 23, input device 24, and display 25. It is possible to use it. Therefore, these explanations will be omitted.

[0041] Processors 21 and 41 are, for example, Central Processing Units (CPUs). U is also called a Microprocessor Unit (MPU). Processors 21 and 41 are single-phase The configuration may be a processor-based or multiprocessor-based configuration. Furthermore, a single physical CPU connected via a single socket may have a multicore configuration. Processors 21 and 41 may include various circuit configurations of arithmetic units, such as Digital Signal Processors (DSPs) or Graphics Processing Units (GPUs). Processors 21 and 41 may also have configurations that interact with at least one of the following: integrated circuits (ICs), other digital circuits, and analog circuits. Integrated circuits include LSIs, Application Specific Integrated Circuits (ASICs), and Programmable Logic Devices (PLDs). PLD This includes, for example, a Field-Programmable Gate Array (FPGA). Processors 21 and 4 1 includes, for example, what are called microcontrollers (MCUs), SoCs (System-on-a-chip), system LSIs, or chipsets. <Example of processing> Figure 6 is a sequence diagram showing an example of sensing information processing in this information communication system. Figure 6 also shows the processing of the receiver 12a, which requests sensing information, and the external device 13, which collects sensing information. Figure 6 exemplifies processing using the Subscribe / Notify method. However, the processing of sensing information in this information communication system is not limited to the Subscribe / Notify method. Sensing information in this information communication system may also be provided using the Request / Response method.

[0042] In this process, first, receiver 12a requests sensing information notification from NEF11e using a Subscribe message (arrow A1). A Subscribe message is a message that requests sensing notification via Notify. The Subscribe message specifies an entry (e.g., ENTRY1) and a condition (e.g., C1). Receiver 12a can request sensing services from NEF11e by specifying different conditions. The entry (e.g., ENTRY1) is information that identifies the condition (e.g., C1) that receiver 12a specifies to NEF11e. Therefore, receiver 12a can request sensing services from NEF11e using Subscribe messages containing different conditions by specifying different entries. NEF11e stores the conditions specified in the Subscribe message in association with the entries.

[0043] Therefore, in the example of arrow A1, the Subscribe message includes entry ENTRY1 and condition C1, as exemplified by Subscribe,ENTRY1,C1. Condition C1 includes, for example, conditions related to the object to be detected, the sensing interval, the sensing time, the sensing accuracy, etc.

[0044] For example, in the example of arrow A1, the Subscribe message is "Subscrib e ENTRY1, Frequency F1, Velocity V1, Size S1, Confidence Co1,…” Here, the conditions identified by ENTRY1 are the sensing frequency F1, the velocity of the object to be detected (V1), the size of the object to be detected (S1), and the confidence level (Co1) are specified. The sensing frequency F1 is SENSING11. n is the time interval for acquiring sensing information from the external device 13. Of the parameters specified in the Subscribe message, parameters other than frequency F1 are used to determine whether the sensing information acquired from the target of detection is sufficient. For this reason, parameters other than frequency F1 are also called sensing conditions (or detection conditions). The detection frequency is set according to the sensing conditions.

[0045] Speed ​​V1 is the speed of movement of the object sensed via the external device 13. Size S1 of the detected object is the size of the object sensed via the external device 13. Condition parameters that specify the attributes of such objects to be sensed may be specified as values ​​within a predetermined range. The predetermined range may be specified, for example, as a minimum value to a maximum value. For example, speed V1 to V2, size S1 to S2, etc. Also, condition parameters that specify attributes may be specified as a specific value and a tolerance value for deviation from that value. For example, speed may be specified as V1 plus or minus 10%. Note that condition parameters that specify the attributes of an object are not limited to speed and size, but include examples such as color, shape, and type of object. Types of objects include people, moving objects, vehicles, shops, etc.

[0046] Confidence Co1 is that SENSING11n is an external device 1 Co1 specifies the confidence or accuracy when determining whether the sensing information obtained from 3 satisfies the conditions specified in the Subscribe message (e.g., C1). In other words, when SENSING11n determines that the sensing information about the detection target reported from the external device 13 satisfies the conditions specified when the sensing information was requested, the percentage of times this determination is correct is Confidence.

[0047] When NEF11e receives a Subscribe message, it saves the condition (e.g., C1) to the specified entry (e.g., ENTRY1). Then, NEF11e returns an Acknowledgement message to receiver 12a (arrow A10). Next, NEF11e requests sensing information from SENSING11n via a Subscribe message specifying condition C1 (arrow A2). In response, SENSING11n returns an Acknowledgement message to NEF11e (arrow A3).

[0048] Furthermore, SENSING11n requests sensing from the external device 13 according to condition C1 (arrow A4). For example, SENSING11n requests the external device 13 to acquire information at the frequency F1 specified by condition C1 in the Subscribe message from NEF11e. More specifically, if the external device 13 is a camera, SENSING11n requests the camera to take images at frequency F1 and notify SENSING11n of the captured images.

[0049] Frequency F1 is exemplified by the number of times information is acquired per unit time. However, frequency F1 may also be the interval, i.e., the time elapsed since the last information acquisition. In this case, the interval can also be a parameter that controls the external device 13 so that the time elapsed since the last new information was detected is less than a predetermined amount. Therefore, frequency F1 can also be considered an example of the information acquisition history.

[0050] In the example in Figure 6, SENSING11n requests information acquisition from external device 13 with a Subscribe message (arrow A4), and external device 13 returns an Acknowledgement message to SENSING11n (arrow A5). Then, external device 13 notifies of the acquired information (e.g., an image) with frequency F1 using a Notify message (arrow A6). This notification by Notify message is repeated until SENSING11n sends a Release message to external device 13 (arrow A44), and external device 13 returns an Acknowledgement message to SENSING11n (arrow A45). However, this notification by Notify message may also be modified by an Update message sent by SENSING11n to external device 13, which updates the sensing condition C1.

[0051] Furthermore, the processing of sensing information by SENSING11n is done via Request / Res When provided via the ponse method, the frequency F1, etc., should be controlled by SENSING11n. That is, SENSING11n should send a sensing Request message to the external device 13 at time intervals corresponding to the frequency F1, and receive sensing information corresponding to the Request message in a Response message. SENSING11n should receive a Release message from NEF11e (arrow A42) and continue sending sensing Request messages to the external device 13 at frequency F1 until the external device 13 returns an Acknowledgement message to NEF11e (arrow A43).

[0052] When SENSING11n receives information (e.g., an image) acquired by the external device 13 via a Notify message, SENSING11n determines whether the acquired information satisfies condition C1. Details of this determination will be explained separately in Figure 7. SENSING11n notifies NEF11e via a Notify message of the information (N11) from the information notified by the external device 13 that satisfies condition C1 (arrow A11). Then, NEF11e notifies receiver 12a of the information (N11) notified by SENSING11n via a Notify message (arrow A12).

[0053] Through this process, receiver 12a can cause external device 1 to detect information that satisfies condition C1 at a specified frequency F1, and acquire information that corresponds to condition C1. Information that corresponds to condition C1 is, for example, an image of a detected object that is moving at a speed V1 (plus or minus 10%), has a size of S1 (plus or minus 10%), and has been identified with a confidence level of Co1. The acquisition of information (N1i) by external device 13 and notification to SENSING 11n (arrow A1i), the determination by SENSING 11n as to whether or not condition C1 is satisfied, and the notification of information (N1i) that satisfies condition C1 to receiver 12a (arrow A1j) are repeated multiple times.

[0054] Next, an example of updating conditions by receiver 12a is shown. Depending on the situation, receiver 12a can request SENSING 11n to acquire information at different frequencies via NEF 11e and notify information that satisfies other conditions Cn, etc. In this case, receiver 12a may request sensing services from NEF 11e with a Subscribe message specifying a different condition Cn in a different entry ENTRY2 than the Subscribe message of arrow A1. However, receiver 12a may also request NEF 11e to update condition C1 to Cn with an Update message in the same entry ENTRY1 as the Subscribe message of arrow A1. From arrow A21 onwards in Figure 6, an example of the process in which frequency F1 is updated to frequency Fn and condition C1 is updated to condition Cn by an Update message is shown.

[0055] In this process, receiver 12a requests NEF 11e to update the sensing conditions with an Update message (arrow A21). Similar to the Subscribe message, the Update message specifies an entry (e.g., ENTRY1) and a condition (e.g., Cn). Receiver 12a can request NEF 11e to update the sensing conditions by specifying different conditions for the entry currently in use with the Update message. As already mentioned, the entry is information that identifies the condition that receiver 12a specifies to NEF 11e.

[0056] In the example of arrow A21, the Update message includes entry ENTRY1 and condition Cn, as exemplified by Update, ENTRY1, Cn. That is, receiver 12a requests NEF11e to change the condition corresponding to ENTRY1 to Cn.

[0057] When NEF11e receives an Update message, it processes the specified entry (for example). The updated conditions (e.g., Cn) are saved in ENTRY1). In the example in Figure 6, the conditions Cn are frequency Fn, velocity Vn, size Sn, confidence Con, ... NEF11e returns an Acknowledgement message to receiver 12a (arrow A30).

[0058] Then, NEF11e requests SENSING11n to update the sensing condition from C1 to Cn by sending an Update message specifying condition Cn (arrow A22). SENSING11n returns an Acknowledgement message to NEF11e (arrow A23).

[0059] Furthermore, SENSING11n requests sensing from the external device 13 according to condition Cn (arrow A24). For example, SENSING11n requests the external device 13 to acquire information at the frequency Fn specified by condition Cn in the Subscribe message from NEF11e. More specifically, if the external device 13 is a camera, SENSING11n requests the camera to take images at frequency Fn and notify SENSING11n of the captured images.

[0060] Then, the external device 13 sends an Acknowledgement message back to SENSING11n (arrow A25). The external device 13 then notifies the information it has obtained (for example, an image) via a Notify message at frequency Fn (arrow A26). This notification via Notify messages is repeated until SENSING11n sends a Release message back to the external device 13 (arrow A44), and the external device 13 sends an Acknowledgement message back to SENSING11n (arrow A45).

[0061] When SENSING11n receives information (e.g., an image) acquired by the external device 13 via a Notify message, SENSING11n determines whether the acquired information satisfies condition Cn. SENSING11n notifies NEF11e via a Notify message of the information (N31) from the information notified by the external device 13 that satisfies condition Cn (arrow A31). Then, NEF11e notifies receiver 12a of the information (N31) notified by SENSING11n via a Notify message (arrow A32). Through this process, receiver 12a can cause the external device 1 to detect information that satisfies condition Cn at a specified frequency Fn and acquire information that corresponds to condition Cn. Information that corresponds to condition Cn is, for example, an image of an object that is moving at a speed Vn (plus or minus 10%), has a size of Sn (plus or minus 10%), and can be identified with a confidence level Con.

[0062] When receiver 12a no longer needs to acquire information from external device 13 or notify information from SENSING 11n, it sends a Release message to NEF 11e (arrow A41). NEF 11e then sends an Acknowledgement message back to receiver 12a (arrow A50). NEF 11e then sends a Release message to SENSING 11n (arrow A42). SENSING 11n then sends an Acknowledgement message back to NEF 11e (arrow A43). SENSING 11n then sends a Release message to external device 13 (arrow A44). External device 13 then sends an Acknowledgement message back to SENSING 11n (arrow A45). As described above, information is exchanged between the receiver 12a, NEF 11e, SENSING 11n, and external device 13 through the Subscribe / Acknowledgement, Notify, Update / Acknowledgement, and Release / Acknowledgement messages.

[0063] Figure 7 shows that SENSING11n notifies NEF11e of information that satisfies the sensing conditions. This flowchart illustrates the process when this occurs. In this process, SENSING11n requests sensing information from the external device 13 by specifying the frequency and conditions (S1). The request for sensing information is, for example, by the Subsribe / Notify method. However, the sensing service may also be, for example, by the Request / Response method. Below, Figure 7 explains an example of processing using the Subsribe / Notify method. An example of parameters specified in the Subsribe message in the Subsribe / Notify method has already been illustrated in Figure 6. Here, it is assumed that frequency F1 and condition C1 are specified.

[0064] Then, SENSING11n determines whether or not sensing information has been notified from the external device 13 via a Notify message (S2). If the determination in S2 is that no information has been notified from the external device 13, SENSING11n proceeds to S5. On the other hand, if the determination in S2 is that sensing information has been notified from the external device 13, SENSING11n determines whether or not the notified sensing information satisfies condition C1 (S3).

[0065] There are no limitations on the method of determining S3. For example, if the sensing information is an image and condition C1 specifies that the image contains a specific object, the determination of S3 may be performed by an AI (Artificial Intelligence) system such as deep learning. The AI ​​system may perform a specific The system should include a pre-trained model that has been machine-learned using still images, videos, etc., that contain a large number of target objects. The pre-trained model should determine whether the sensing information (still images, videos) notified from the external device 13 contains any target objects that meet condition C1. Note that the Confidence condition in C1 may be set based on the level of training the pre-trained model has received.

[0066] In the S3 determination, if the notified sensing information satisfies condition C1, SENSING11n notifies NEF11e of the sensing information (S4). Then, SENSING11n determines whether or not to terminate the process (S5). The process is terminated when SENSING11n receives a Release message from NEF11e.

[0067] If SENSING11n does not terminate processing based on the judgment in S5, it determines whether it has received a condition update instruction from NEF11e (S6). Here, the conditions are the same as those described in Figure 6, and include frequency. If SENSING11n receives a condition update instruction within the predetermined period based on the judgment in S6, it notifies the external device of the updated conditions (including frequency) (S7). Then, SENSING11n returns processing to S2. If SENSING11n does not receive a condition update instruction within the predetermined period based on the judgment in S6, it returns processing to S2 as is.

[0068] Furthermore, if SENSING11n terminates processing based on the S5 determination, it notifies the external device 13 of the termination (Release). SENSING11n then terminates processing after receiving an acknowledgment from the external device 13.

[0069] <Effects of the Embodiment> As described above, according to this embodiment, the NEF11n, as a control unit, receives conditions including the frequency of responding with information from the receiver 12a, and responds with information detected by the SENSING11n based on the received frequency. More specifically, the NEF11n requests the SENSING11n to acquire information at the received frequency and notify the SENSING11n of information that satisfies condition C, which is specified as a sensing condition. The SENSING11n, as a control unit, acquires information from the external device 13, determines whether the acquired information satisfies condition C, and notifies the NEF11n of information that satisfies condition C. The NEF11n also notifies the receiver 12a of the information notified by the SENSING11n. Therefore, in this information communication system, the NEF11n and SENSING11n act as control units and respond to the receiver 12a. Then, at the desired timing, information that satisfies the conditions specified by receiver 12a can be notified.

[0070] Furthermore, according to this embodiment, the NEF 11n, as a control unit, receives conditions including different frequencies from the receiver 12a and requests the SENSING 11n to notify it of information. At least one of the NEF 11n and SENSING 11n, as a control unit, holds conditions including frequencies in association with the corresponding entries (ENTRY1, etc.), so that the SENSING 11n can acquire information satisfying the desired conditions from the external device 13 at a specified frequency and notify the receiver 12a of the acquired information via the NEF 11e. Therefore, the receiver 12a can efficiently acquire the desired information at an appropriate time by accessing this information communication system. In other words, since the frequency of information acquisition by the external device 13 is adjusted in this information communication system, it is possible to save communication resources required for transmitting sensing information, for example.

[0071] Condition C, as a sensing condition, may include at least one of the following: whether or not the detected object is moving, its speed, its size, the history of the information on the detected object (the time elapsed since initial detection is less than a predetermined value), and the required level of confidence for the information. Therefore, this information communication system can identify various attributes of the detected object, narrow down the detected object, and acquire information related to the detected object. Note that if the detected object is not moving, the speed of movement is 0, and if it is moving, the speed of movement will be a value other than 0. For this reason, the presence or absence of movement can be included in the speed of movement.

[0072] Furthermore, this information communication system includes a SENSING11n as a detection unit that detects information related to the target to be detected. The NEF11e, acting as a control unit, specifies a condition C including frequency to the SENSING11n and subscribes to the SENSING11n for detection. The SENSING11n then notifies the NEF11e of information that satisfies condition C1. The NEF11e then further notifies the receiver 12a, the requester, of the information notified by the SENSING11n. Therefore, this information communication system can process information appropriately and efficiently by coordinating between the NEF11e, which acts as an interface with the receiver 12a, the information requester, and the external device 13, the information acquisition destination. Consequently, this information communication system can provide information to the receiver 12a at a reasonable cost when the receiver 12a performs processing such as generating and updating a dynamic map.

[0073] (Second Embodiment) Referring to Figure 8, an information communication system according to the second embodiment is described. In the first embodiment, an information communication system was exemplified that receives conditions including the frequency of responding with information from the receiver 12a and responds with information based on the received frequency. In the first embodiment, an information communication system was exemplified that receives conditions including different frequencies from the receiver 12a and responds with information that satisfies the conditions at the specified frequency. In this embodiment, the processing of an information communication system including the receiver 12a is exemplified. In this embodiment, the receiver 12a updates a dynamic map, for example.

[0074] Figure 8 is a flowchart illustrating the processing of receiver 12a. Receiver 12a requests the acquisition of sensing information from 5GNW, for example, NEF11n (hereinafter the same) (S11). The request for acquisition of sensing information can be made using either the Subscribe / Notify method or the Request / Response method. Receiver 12a then receives the sensing results from NEF11n (S12). Receiver 12a then uses the received information. For example, receiver 12a updates the dynamic MAP based on the received information (S13).

[0075] Next, receiver 12a determines whether to continue receiving sensing results (S14). Continuing to receive sensing results means that the processing period set by the operator or the like has not yet elapsed. If receiver 12a continues to receive sensing results, it determines whether to change the sensing conditions, including the frequency of acquiring sensing information (S15). The determination of whether to change the sensing conditions can also be expressed as whether to change the sensing request. These conditions can be set, for example, by the operator of receiver 12a.

[0076] If a change in sensing conditions is necessary, receiver 12a sends an Update message to 5GNW (S16). Then, receiver 12a returns to processing S12. On the other hand, if no change in sensing conditions is necessary, receiver 12a returns to processing S12 as is.

[0077] Furthermore, if the receiver 12a does not continue to receive sensing results based on the determination in S14, it sends a Release message to 5GNW (S17).

[0078] As described above, according to this embodiment, when the receiver 12a continuously receives sensing results, it can determine whether or not it is necessary to change the sensing conditions and set the sensing conditions, including the desired frequency, to 5GNW. In other words, the information communication system including the receiver 12a can acquire sensing information at the desired frequency and sensing conditions.

[0079] The receiver 12a can change the sensing frequency according to, for example, the time of day, the confidence level of the sensing result, the speed of the detected object, etc. For example, the sensing frequency for fixed objects such as buildings will be set lower than predetermined. However, newly appearing fixed objects, such as obstacles or traffic signs, should be updated at a higher frequency than normal fixed objects.

[0080] (Third embodiment) The information communication system according to the third embodiment will be described below with reference to Figure 9. In the second embodiment described above, the information communication system including the receiver 12a determined whether it was necessary to change the sensing conditions, including the sensing frequency, set the sensing conditions to 5GNW, and acquired sensing information. In this embodiment, an information communication system is described in which the NEF 11e or SESING 11n, acting as the control unit of the information communication system, can set the frequency of acquiring sensing information and the sensing conditions.

[0081] Figure 9 illustrates the processing of NEF11e and SENSING11n as control units in this embodiment of the information communication system. Although the processing of external device 13 is omitted in Figure 9, external device 13 operates in the same manner as in Figure 6. In this process, first, receiver 12a requests notification of sensing information from NEF11e with a Subscribe message (arrow A51). Then, NEF11e returns an Acknowledgement message to receiver 12a (arrow A52).

[0082] A key feature of this information communication system is that the receiver 12a can specify multiple entries to the NEF 11a. For example, the receiver 12a can specify condition C3 for ENTRY3 and condition C4 for ENTRY4, such as Subscribe ENTRY3, C3, ENTRY4, C4.

[0083] Here, the conditions C3 specified in ENTRY3 are area AR1, velocity V1, confidence Co1, time window (7am-9am), frequency F1, ... Condition C3 specifies, for example, that information about a detection target moving at speed V1 in a geographic area AR1 be acquired with confidence level C1. That is, area AR1 specifies, for example, the area where the detection target is located. Furthermore, condition C3 specifies that information about the detection target be acquired with frequency F1 during a time window (7am-9am), that is, between 7am and 9am. Here, the specification of area AR1, that is, the specification of area AR1 to be sensed, is an example of geographical information. When the detection target changes over time, the information about the detection target that satisfies condition C3 can be said to be dynamic information when an object related to geographical information changes over time. Here, time window (7am-9am) is an example of a selection condition, as it specifies whether or not condition C3, which is a sensing condition, is selected.

[0084] Furthermore, the conditions C4 specified in ENTRY4 are area AR1, velocity V1, confidence Co1, time window (9am-11am), frequency F2, etc. Condition C4 specifies, for example, that information on a detection target moving at velocity V1 in geographic area AR1 be acquired with confidence Co1. In addition, condition C4 specifies that information on the detection target be acquired at frequency F2 during the time window (9am-11am), i.e., between 9am and 11am. Note that in conditions C3 and C4, the location of the detection target may be specified instead of area AR1. The location is specified, for example, as a range of latitude and longitude, and is almost synonymous with area. Here, time window (9am-11am) is also an example of a selection condition, as it specifies whether or not condition C4, which is a sensing condition, is selected.

[0085] Next, NEF11e selects the corresponding entry (S101). In this embodiment, NEF11e obtains the current time and determines whether the time window is satisfied. For example, if the current time satisfies the time window (7am-9am), NEF11e selects ENTRY3. Then, specifying condition C3, it sends a Subscribe message to SENSING11n (arrow A53). SENSING11n then returns an Acknowledgement message to NEF11e (arrow A54). SENSING11n then receives notification of information (N31) from the external device 13 at frequency F1 and notifies NEF11e of the information (N31) that satisfies condition C3 (arrow A55). Furthermore, NEF11e notifies receiver 12a of the information that satisfies condition C3 (arrow A56).

[0086] Then, NEF11e determines whether or not it is necessary to change the update frequency (S102). For example, in the example in Figure 9, NEF11e determines whether or not the current time satisfies the time window (7am-9am) condition. If the current time satisfies the time window (7am-9am) condition, NEF11e continues sensing under condition C3. That is, notifications by arrows A55 and A56 are repeated until the time window (7am-9am) condition is no longer satisfied.

[0087] On the other hand, if the current time does not satisfy the time window (7am-9am) condition, NEF11e determines whether the current time satisfies the time window (9am-11am) condition C4. If the current time satisfies the time window (9am-11am) condition, NEF11e selects ENTRY4 (S103) and sends an Update message to SENSING11n so that it can be sensed under condition C4 (arrow A57). SENSING11n then returns an Acknowledgement message to NEF11e (arrow A58).

[0088] In this way, time window time window (9am-11 At 9am-11am, the sensing conditions are updated to condition C4 of ENTRY4, and sensing is performed. Then, SENSING11n receives information (N41) from external device 13 at frequency F2 and notifies NEF11e of the information (N41) that satisfies condition C4 (arrow A59). Furthermore, NEF11e notifies receiver 12a of the information (N41) that satisfies condition C4 (arrow A60). In this way, notifications by arrows A59 and A60 are repeated until the conditions of the time window (9am-11am) are no longer satisfied.

[0089] Note that the time window is not limited to 7 AM to 9 AM or 9 AM to 11 AM; other time slots can also be specified. NEF11n simply selects the sensing conditions for the corresponding entry from the current time and the specified time window, and sends a Subscribe message or Update message to SENSING11n.

[0090] Furthermore, the processing of NEF11e in this embodiment is not limited to switching entries based on a time window. Receiver 12a can specify various entry selection conditions. For example, NEF11e may specify selection conditions based on whether it is morning or afternoon of the day, the day of the week, the date, the season, etc. Multiple entry selection conditions may also be specified. Multiple specified entry selection conditions may be joined using OR logic or AND logic.

[0091] For example, the Subscribe message indicated by arrow A51 in Figure 9 may be generalized as follows:

[0092] (Formula 1) Subscribe ENTRY1: Element condition D11, Element condition D12, ..., Element condition D1N, (Logical expression R1), Selection condition T11, Selection condition T12, ..., Selection condition T1M, (Logical expression R2), Frequency F1, ENTRY2: Element condition D21, Element condition D22, ..., Element condition D2N, (Logical expression R1), Selection condition T21, Selection condition T22, ..., Selection condition T2M, (Logical expression R2), Frequency F2, …) Here, “element condition D11, element condition D12, ..., element condition D1N” are conditions related to the object to be detected, such as speed, size of the object to be detected, and sensing area. Similarly, “element condition D21, element condition D22, ..., element condition D2N” are also conditions related to the object to be detected. Logical expression R1 is a logical expression that combines multiple element conditions. The logical expression combines each of the element conditions “element condition D11, element condition D12, ..., element condition D1N”, and the conditions defined by the combined logical expression are specified as sensing conditions. Frequency F1 is the frequency specified for this entry.

[0093] Furthermore, “Selection Condition T11, Selection Condition T12, ..., Selection Condition T1M” are conditions that specify whether or not to apply the entry to sensing. Similarly, “Selection Condition T21, Selection Condition T22, ..., Selection Condition T2M” are conditions that specify whether or not to apply the entry to sensing. Logical expression R2 is a logical expression that combines multiple selection conditions. The logical expression combines each of the selection conditions in “Selection Condition T11, Selection Condition T12, ..., Selection Condition T1M” and the combined expression The condition of the entry is designated as a sensing condition if the logic defined by the logical expression is true. Frequency F2 is the frequency specified for the entry.

[0094] As described above, according to this embodiment, the NEF11e or SENSIG11n, acting as a control unit, receives multiple entries and selection conditions for selecting an entry in a Subsribe message, and if the selection conditions are met, it can set the conditions specified in the entry as sensing conditions.

[0095] Furthermore, according to this embodiment, the NEF11e or SENSIG11n, acting as a control unit, can specify logical expressions for multiple element conditions and multiple selection conditions. The control unit can then determine that the target satisfies the selection condition when the logical expression of an element condition is true, extract sensing information, and notify it. Alternatively, when the logical expression of a selection condition is true, the control unit can adopt the sensing condition (logical expression of an element condition) for that entry and set it as the sensing condition. For example, if the logical expression of a selection condition is true, the NEF11e can determine the sensing information according to the logical expression of the element condition for that entry, and if the sensing information makes the logical expression true, it can request the SENSIG11n to notify the sensing information. The SENSIG11n can then notify the NEF11e of the sensing information when the logical expression of an element condition is true, and the NEF11e can further notify the receiver 12a of the notified sensing information.

[0096] As described above, in this embodiment, the NEF11e, acting as the control unit, accepts multiple sensing conditions identified by entries as identification information. Each sensing condition is associated with a selection condition. The control unit then selects the sensing condition that satisfies the selection condition and acquires sensing information from the target. Therefore, this information communication system can change the sensing conditions according to the situation and perform sensing services.

[0097] <Variation> As described above, in Figure 9, the NEF11e or SENSIG11n, acting as the control unit, selects sensing conditions that satisfy the selection criteria, acquires sensing information from the detection target, and extracts sensing information that satisfies the selected sensing conditions. Alternatively, the NEF11e, acting as the control unit, may change the detection frequency according to the detected information. Here, the Subsribe message may be specified as follows.

[0098] (Formula 2) Subscribe ENTRY1: Element condition D1, Element condition D2, ..., Element condition DN, (Logical expression R1), Initial frequency, Selection condition T1, frequency F1, selection condition T2, frequency F2, ..., selection condition TK, frequency FK Here, the elemental conditions D1, etc., are the same as in (Equation 1) above.

[0099] Element condition D1 is, for example, speed V1 to speed V2. Element condition D22 is, for example, SIZE S1 to SIZE S2. Similarly, element condition DN specifies the attribute to be detected. The initial frequency is the frequency initially set when the sensing service is requested via Subscribe.

[0100] Selection condition T1 is a condition obtained by subdividing one of element conditions D1, D2, ..., DN, or a condition obtained by subdividing and combining one or more of them. For example, assume that element condition D1 is a speed between 30 km and 60 km. In this case, selection condition T1 is, for example For example, the speed is 40 km to 50 km. Also, assume that element condition D2 is size 0.5 m to 5 m. In this case, selection condition T2 is, for example, speed 40 km to 50 km and size 1 m to 2 m. The control unit NEF11e or SENSIG11n selects frequency F1 when selection condition T1 is satisfied. The same applies to selection conditions T2 to TK.

[0101] Figure 10 is a flowchart illustrating the processing of SENSING11n according to this modified example. In this process, the processes S1 to S5 and S8 are the same as in Figure 7, so their explanation is omitted. If SENSING11n does not terminate the process at the determination in S5, it determines whether or not a frequency update is necessary for the sensing result (S6A). That is, it determines whether or not the attributes of the detection target sensed from the current detection target satisfy any of the selection conditions T1 to TK. If the sensed attributes of the detection target satisfy one of the selection conditions T1 to TK, for example, selection condition T1, SENSING11n selects a frequency F1 as an example of a second detection frequency corresponding to selection condition T1, and notifies the external device 13 of an Update message (S7A).

[0102] However, the process in Figure 10 is not limited to SENSING11n. For example, NEF11e may perform the process in Figure 10 instead of SENSING11n. If NEF11e performs the process in Figure 10, in the S7A process, NEF11e should select the frequency F1 corresponding to the selection condition T1 that satisfies the attribute of the target to be detected, and notify SENSING11n of an Update message.

[0103] According to the above modifications, this information and communication system can set an appropriate frequency according to the attributes of the object to be detected and provide sensing services.
