DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] It is conceivable that the system receives a request from a user terminal, detects the position and traveling direction of the user terminal, and notifies the user terminal of information including the position and traveling direction of the user terminal. As an example, the user terminal is a mobile communication terminal. In such a system, the user terminal may wish to obtain not only its own position and traveling direction, but also the position and traveling direction of an object other than itself. As an example, the object other than the user terminal may be a mobile communication terminal other than the user terminal. For example, the user terminal may wish to obtain the traveling direction of an object existing on its path for safe movement. Therefore, it is desirable for the system to detect the position and traveling direction of not only the user terminal that transmitted the request, but also any object designated by the user terminal, and notify the user terminal.

[0011] A system according to one aspect of the present disclosure includes: A system constituting a wireless communication network includes a processor that executes the following operations: receiving an acquisition request for information including a traveling direction of an object to be detected; and transmitting first sensing information, which is a sensing result of the object, including information indicating the traveling direction of the object, based on the acquisition request.

[0012] An example of the wireless communication network is a system using 5G, 4G, LTE, LTE-A, SUPER 3G, IMT-Advanced, NR, etc., and a next-generation system expanded based on these. Other examples of the wireless communication network are IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, UWB, Bluetooth (registered trademark), and other systems and a next-generation system expanded based on these. The wireless communication network may be a system in which a plurality of systems are combined.

[0013] The object to be detected is typically a mobile communication terminal other than the user terminal. Note that the object to be detected does not have to be a mobile communication terminal. The object to be detected may be any object that does not have a communication function.

[0014] The direction of travel is the direction in which an object is moving when it is moving from one point to another. The direction of travel may be expressed as north, south, east, or west, or may be expressed as an azimuth angle.

[0015] This allows the system according to the present disclosure to notify the UE (terminal) of the traveling direction of an object inquired about by the UE.

[0016] Further, the acquisition request includes a first ID that is an ID of a first terminal that is a terminal connected to the wireless communication network, and the processor, based on the first ID, calculates a traveling direction of the object to be detected based on a traveling direction of the first terminal as the first sensing information. The information may be sent by including it in the

[0017] This allows the system according to the present disclosure to relatively identify the traveling direction of the object to be detected and the UE, and therefore the system according to the present disclosure can determine the traveling direction of the object to be detected based on the relative direction with respect to the traveling direction of the UE that transmitted the sensing request.

[0018] The processor may also determine, based on the first ID, whether the direction of travel of the first terminal and the object to be detected are the same, and transmit the determination result in the first sensing information as information indicating the direction of travel.

[0019] In this way, the system according to the present disclosure can identify whether the traveling direction of the object to be detected is the same as that of the UE, and can relatively determine the traveling direction of the object to be detected based on the traveling direction of the UE that has transmitted the sensing request.

[0020] The processor may also transmit a second ID, which is an ID of a second terminal having the same traveling direction as the traveling direction of the object, as information indicating the traveling direction in the first sensing information.

[0021] This allows the system of the present disclosure to provide information regarding the ID of a UE traveling in the same direction as the object being detected.

[0022] The processor may also include, in the first sensing information, an order in which a plurality of base stations and the object to be detected are connected as information indicating the traveling direction, and transmit the information.

[0023] A UE (terminal) connected to the core network connects to the nearest base station, but as the UE (terminal) moves, the base station it connects to also changes. Therefore, if the detected object is connected to the core network, it is possible to determine the object's direction of travel based on the connection history between the object and the base station.

[0024] This allows the system according to the present disclosure to determine the direction of travel of the detected object based on the object's connection history with the base station.

[0025] In addition, a terminal according to the present disclosure performs the following steps: sending an acquisition request for information including a traveling direction of a detected object to a core network; and acquiring first sensing information, which is a sensing result of the detected object including the traveling direction of the detected object, from the core network.

[0026] As a result, the terminal according to the present disclosure can achieve the same effects as the above system.

[0027] Specific embodiments of the present disclosure will be described below with reference to the drawings. Unless otherwise specified, the hardware configuration, module configuration, functional configuration, etc. described in each embodiment are not intended to limit the technical scope of the disclosure to only those. For example, an example in which the present disclosure is applied to a fifth generation mobile communication system will be described below, but the present disclosure may also be applied to a fourth generation mobile communication system or a generation after the fifth generation. The present disclosure may also be applied to a mobile communication system defined by a system other than 3GPP (registered trademark), or to any wireless communication system or wired communication system other than a mobile communication system. In addition, it is assumed that the data provided and used by the user terminal is sensing data measured by the user terminal. However, the data provided and used may be data stored in a user terminal. The data may be sensing data measured by a device other than the user terminal, or may be any data other than sensing data.

[0028] (Embodiment) FIG. 1 shows components constituting a fifth generation mobile communication system (5G network). 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 composed of base stations (gNB). The 5G network has a 5G core network (5GC) and an access network ((R)AN), and a UE 2, a DN 5, and an AF 12 are connected to the 5G network. Each of NFs 11a to 11m is a function realized by one or more computers (information processing devices) executing a program. However, a single computer may realize two or more of NFs 11a to 11m. Each of NFs 11a to 11m can also be referred to as a network node or a network component. The components shown in FIG. 1 realize a system 100 according to an embodiment.

[0029] 5GC is composed of a set of components with specific functions called NFs (Network Functions). Figure 1 shows the following as NF11 that composes 5GC. In Figure 1, the multiple elements that compose NF11 are shown as thick rectangles.

[0030] 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 SENSING (Sensing Function) 11m

[0031] The UPF 11a performs routing and forwarding of user packets (user plane packets transmitted and received by the UE 2), packet inspection, and QoS processing.

[0032] The AMF 11b is a device for accommodating UEs in the 5GC. The AMF 11b accommodates the RAN 3 and performs subscriber authentication control and location (mobility) management of the UE 2.

[0033] The SMF 11c manages a PDU (Protocol Data Unit) session and controls the UPF 11a to implement QoS (Quality of Service) control and policy control. The PDU session is a virtual communication path for exchanging data between the UE 2 and a DN (Data Network) 5. The DN 5 is a data network (such as the Internet) outside the 5GC.

[0034] The PCF 11d performs QoS control, policy control, billing control, etc. under the control of the SMF 11c. QoS control controls the quality of communication, such as by prioritizing packet forwarding. Policy control controls communication, such as QoS based on network or subscriber information, whether or not to forward packets, and billing.

[0035] NEF11e acts as an intermediary between external nodes and nodes within the control plane. .

[0036] The NRF 11g stores and manages information on NFs (e.g., AMF, SMF, UPF, etc.) in the 5GC. In response to an inquiry about an NF to be used, the NRF 11g can return multiple NF candidates to the inquiry source.

[0037] The NSSF11h has a function of selecting a network slice to be used by a subscriber from among the network slices generated by network slicing. A network slice is a virtual network with specifications according to the application.

[0038] The AUSF 11i is a subscriber authentication server that performs subscriber authentication under the control of the AMF 11b.

[0039] The UDM 11j holds subscriber-related information, and provides subscriber information, or obtains, registers, deletes, and changes the status of the UE 2.

[0040] NWDAF11k has the function of collecting and analyzing data from each NF11 and external servers. It is an NF that provides network analysis information.

[0041] SENSING11m performs sensing services including collecting sensing information from UE2, RAN3 (base station (gNB)) or other nodes, and providing the collected sensing information to UE2 or other external systems (AF12, DN5, etc.). Details of SENSING11m will be described later.

[0042] The AF12 is an NF that provides application services via the NRF11g as part of the 5GC, or an NF that is outside the 5GC and provides application services via the NEF11e. The AF12 performs processing using sensing data, for example. As an example, the AF12 notifies the UE (terminal) of information indicating the position and traveling direction of a detected object acquired by the SENSING11m. Note that the information does not need to include the position. Also, an application program executed in the UE (terminal) may operate as the AF12.

[0043] In 5GC, multiple NFs of the same type may be prepared. For example, an NF 11 may be prepared for each data center (station). Also, one NF 11 may be shared between data centers. Also, multiple NFs 11 of the same type may be configured in one data center. The number of data centers, the number of NFs 11, and the correspondence between the NFs 11 and the data centers may be set appropriately.

[0044] <Configuration of information processing device and terminal> Fig. 2A is a diagram showing a configuration example of an information processing device 20 operable as the system 100 according to the embodiment. In Fig. 2A, the information processing device 20 can be configured using a dedicated or general-purpose information processing device (computer) such as a personal computer (PC), a workstation (WS), or a server machine. However, the information processing device 20 may be a collection (cloud) of one or more computers.

[0045] The information processing device 20 includes a processor 21 serving 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, which are interconnected via a bus 26.

[0046] The storage device 22 includes a main storage device and an auxiliary storage device. The main storage device stores programs and It is used as at least one of a data storage area, a program expansion area, a program working area, and a buffer area for communication data. The main storage device is configured with a RAM (Random Access Memory) or a combination of a RAM and a ROM (Read Only Memory). The auxiliary storage device is used as a data and program storage area. A non-volatile storage medium is applied to the auxiliary storage device. Examples of the non-volatile storage medium include a hard disk, a Solid State Drive (SSD), a flash memory, and an EEPROM (Electrically Erasable Programmable Read-Only Memory). The storage device 22 may also include a drive device for a disk recording medium.

[0047] The communication IF 23 is a circuit that performs communication processing. For example, the communication IF 23 is a network interface card (NIC). The communication IF 23 may be a wireless communication circuit that performs wireless communication (5G, wireless LAN (Wi-Fi (registered trademark)), BLE, etc.). Moreover, the communication IF 23 may be a combination of a circuit that performs wired communication processing and a wireless communication circuit.

[0048] The input device 24 includes keys, buttons, a pointing device, a touch panel, etc., and is used to input information. The display 25 is, for example, a liquid crystal display, etc., and displays information and data.

[0049] The processor 21 performs various processes by executing various programs stored in the storage device 22. The processor 21 executes the programs stored in the storage device 22, so that the information processing device 20 can operate as each of the NFs 11a to 11m and the external servers 12a and 12b. The processor 21 is a specific example of a control unit of the system 100.

[0050] 2B is a diagram showing a configuration example of a terminal 40 operable as a UE 2. The terminal 40 is an example of a first terminal. 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, which are mutually connected via a bus 46. The processor 41, the storage device 42, the communication IF 43, the input device 44, and the display 45 can be similar to the processor 21, the storage device 22, the communication IF 23, the input device 24, and the display 25. Therefore, description thereof will be omitted.

[0051] The processors 21 and 41 are, for example, Central Processing Units (CPUs). The PU is also called a Microprocessor Unit (MPU). The processors 21 and 41 may have a single processor configuration or a multi-processor configuration. Also, a single physical CPU connected via a single socket may have a multi-core configuration. The processors 21 and 41 may include arithmetic devices of various circuit configurations, such as a Digital Signal Processor (DSP) or a Graphics Processing Unit (GPU). Also, the processors 21 and 41 may have a configuration in which they cooperate with at least one of an integrated circuit (IC), other digital circuits, and analog circuits. The integrated circuit may be an LSI, an application specific integrated circuit (ASIC), a programmable logic device (PLD), etc. The PLD includes, for example, a Field-Programmable Gate Array (FPGA). The processors 21 and 41 include, for example, what is called a microcontroller (MCU), a system-on-a-chip (SoC), a system LSI, or a chip set.

[0052] <System Operation> 3 is a sequence diagram of sensing processing executed by a control unit of the system according to the embodiment. Note that the sequence diagram shown here is an example, and may include processing other than that shown in the diagram, may omit some of the processing shown in the diagram, and may change the execution order of the processing shown in the diagram. You may change it.

[0053] In this operation example, the UE 2 that transmits a sensing request to SENSING 11m corresponds to a mobile communication terminal that uses this service, and SENSING 11m and NWDAF 11k correspond to applications that provide this service.

[0054] In step S10, a UE 2 that requests sensing of an object transmits a request message to the SENSING 11m to request sensing data. The message includes a parameter for identifying the object to be detected. The parameter for identifying the object to be detected may represent, for example, the area in which the object exists, the shape of the object, the moving speed, and a flag indicating the notification method of the traveling direction. A first example of the notification method is a method in which the ID of a specific UE is stored in the request message and the traveling direction of the object to be detected is notified based on the traveling direction of the UE. Examples of the notification method based on the traveling direction of the specified UE include a method of notifying whether the traveling directions are the same or different, whether the traveling directions are the same or opposite, and a specified angle based on the traveling direction of the specified UE. A second example of the notification method is a method of notifying using the service area of ​​a base station. By notifying at least two base stations, it is possible to grasp in which direction the object to be detected is moving. A third example of the notification method is a method of notifying the ID of another UE that has the same traveling direction as the object to be detected. A fourth example of the notification method is a method of specifying the traveling direction of the object to be detected by an azimuth angle. The UE2 transmits a request message including a parameter indicating which notification method is desired for the sensing data to be notified. In addition, the UE2 may transmit a request message to the SENSING11m via the AF12.

[0055] In step S11, SENSING11m acquires the result of sensing (sensing information) for the object to be detected. For example, SENSING11m transmits a data request message to a base station or a UE other than UE2. The data request message also includes a parameter for identifying the object to be detected. The parameter for identifying the object to be detected is the same as that of the request message.

[0056] SENSING11m may acquire the result of wireless sensing performed by the base station on the object to be detected. In addition, SENSING11m may communicate with a UE other than UE2 and acquire the result of wireless sensing performed by the other UE on the object to be detected.

[0057] In step S12, the SENSING 11m that has received the request message from the UE 2 transmits a mobility request message to the NWDAF 11k. The mobility request message includes the UE ID of the object to be detected.

[0058] In step S13, the NWDAF 11k transmits a mobility response including statistical information corresponding to the UEID of the detected object. The mobility response includes an analysis result of the traveling direction of the detected object. The traveling direction of the object may be represented as a handover history in which the detected object is connected to the base station.

[0059] In step S14, the SENSING 11m that has received the data response from the NWDAF 11k transmits first sensing information as a sensing response to the UE 2. The first sensing information includes information corresponding to the area in which the object exists, the shape of the object, the moving speed, the traveling direction, and the like.

[0060] Next, a process executed by the control unit of the system 100 according to the embodiment will be described. FIG. 4 is a flowchart of a sensing process executed by the control unit of the system according to the embodiment. Specifically, the process described in FIG. 4 is performed by using information that can operate the system 100. It may be executed by the processor 41 of the processing device 20.

[0061] First, in step S20, the control unit receives a request for acquiring the position and traveling direction of a detection target object from the UE 2. The control unit receives a request message from the UE 2 indicating a request for the area in which the object exists, the shape of the object, the moving speed of the object, and the traveling direction information of the object as information related to the detection target object. Note that the acquisition request does not necessarily include a request for acquiring the position of the object.

[0062] Next, in step S21, SENSING11m acquires the result of sensing (sensing information) for the object to be detected. For example, SENSING11m may communicate with a base station and acquire the result of wireless sensing performed by the base station for the object to be detected. SENSING11m may also communicate with a UE other than UE2 and acquire the result of wireless sensing performed by the other UE for the object to be detected.

[0063] Next, in step S22, SENSING 11m determines the traveling direction of the object to be detected based on the sensing result of the object to be detected. The process of SENSING 11m determining the traveling direction of the object to be detected will be described in detail with reference to FIGS.

[0064] Next, in step S23, the control unit transmits the first sensing information to the UE2. Here, the first sensing information is information that indicates the result of sensing the object to be detected, and may include the area in which the object exists, the shape of the object, the moving speed of the object, and the traveling direction information of the object. The control unit acquires the result of wireless sensing of the object to be detected, and transmits information including the position and traveling direction of the object to the UE2. Note that the first sensing information does not need to include the position of the object.

[0065] There are various possible ways of expressing the travel direction information included in the first sensing information. The first example is an expression of travel based on the UE (first terminal) included in the request message. For example, the travel direction of the object to be detected may be expressed as being the same as or opposite to that of the first terminal, or may be expressed as an angle based on the moving direction of the first terminal. The second example is an expression that expresses the travel direction of the object to be detected using at least two base stations. In this case, the travel direction can be specified as the direction from the first base station cell to the second base station cell. In the second example, the handover history of the object to be detected may be included in the first sensing information as it is. The third example is a method of expressing the travel direction of the object to be detected using a UE having the same travel direction as the object to be detected. The fourth example is a method of expressing the travel direction of the object to be detected by a direction such as east-west, north-south, or an azimuth angle.

[0066] 5 is a flowchart of a process of determining the traveling direction of an object based on the order of connection with base stations, which is executed by the control unit of the system 100 according to the embodiment. For example, the system 100 can determine the traveling direction of the object to be detected based on the connection history of the object to be detected with the base station. Note that the method of determining the traveling direction of the object to be detected is not limited to this.

[0067] First, in step S30, the control unit acquires the order in which the object to be detected connected to the base station. In step S31, the control unit determines the traveling direction of the object based on the acquired connection order of the base stations. If the object is an object that connects to a base station by wireless communication, the control unit acquires a connection history with multiple base stations and determines the order in which the object connected to the multiple base stations. As the object moves, it connects to base stations in the vicinity of the area in which it is located at any given time, so the direction in which the base stations are arranged in the order in which they were connected to the object may be determined to be the traveling direction of the object. Specifically, SENSING11m may acquire statistical information linked to the UEID of the object to be detected from NWDAF11k. The statistical information may be used to determine the traveling direction of the object. The information includes the handover history of the detected object.

[0068] However, the method of determining the traveling direction of the object to be detected is not limited to this. The control unit may determine the traveling direction of the object to be detected from the history of the detected position of the object to be detected. In this case, the traveling direction of the object to be detected is represented by, for example, an azimuth angle.

[0069] 6 is a conceptual diagram showing that a first terminal of the system according to the embodiment is connected to a plurality of base stations. As the object to be detected (for example, any UE 3) moves, it sequentially connects to the base station corresponding to each cell in which it is located. The system 100 has a function of determining the relative direction between the UE (terminal) that has transmitted a sensing request for the object to be detected and the object to be detected. Therefore, the system 100 can relatively determine the traveling direction of the object to be detected from the traveling directions of the object to be detected and the UE (terminal) that has transmitted the sensing request.

[0070] 6, UE3 is first connected to base station 500A. Then, as UE3 moves, UE3 disconnects from base station 500A and connects to base station 500B. As UE3 moves further, UE3 disconnects from base station 500B and connects to base station 500C.

[0071] In this way, the UE 3 connects to each of the multiple base stations in turn. Then, the system 100 can determine the relative traveling direction of the object to be detected based on the traveling direction of the UE 3 determined from the connection history with the multiple base stations.

[0072] The control unit of the system 100 may notify the direction of travel of the detected object by an azimuth angle, or may notify by the order of connected base stations.

[0073] There are several methods for notifying the moving direction of the detected object. Each method will be described below.

[0074] 7 is a flowchart showing the process of the control unit of the system 100 according to the embodiment when notifying the traveling direction of the detection target based on the moving direction of the first terminal. In this case, the request message includes the ID of the first terminal.

[0075] First, in step S40, the control unit acquires the traveling direction of the first terminal and the detection target. In step S40, the control unit may acquire each of the traveling direction of the first terminal and the traveling direction of the detection target, or may acquire the relative traveling direction of the first terminal and the detection target. Each traveling direction can be acquired by the above-mentioned method. The relative traveling direction can be acquired, for example, by the method specified in TS23.273 6.20.

[0076] In step S41, the control unit expresses the traveling direction of the detection target based on the traveling direction of the first terminal. As an example, the control unit may determine whether the traveling direction of the detection target is the same direction as or opposite to the traveling direction of the first terminal, or may determine the angle of the moving direction of the detection target based on the traveling direction of the first terminal. In step S42, the control unit generates first sensing information including the traveling direction information of the detection target, and transmits the first sensing information to the UE2 by including it in a data response.

[0077] 8 is a conceptual diagram of a process in which the traveling direction of a detection target is notified using another UE traveling in the same direction. For example, when notifying the traveling direction of a sensing target object, the system 100 can notify using the ID (second IE) of another UE traveling in the same direction as the object.

[0078] First, the UE 2 transmits a request message requesting sensing data to the system 100. Then, the system 100 acquires information such as the traveling direction of the object 300, which is the object to be detected.

[0079] Next, the system 100 detects another UE (the second UE) moving in the same direction as the moving direction of the object 300 and obtains its UE ID. This UE ID is referred to as the second ID. It is desirable that the second UE knows its moving direction. Therefore, the UE2 may notify the system 100 of candidates for the second UE in advance, and the system 100 may select the second UE from among the candidates. Alternatively, the system 100 may assume that the moving direction in the vicinity of the UE2 is known to the UE2 and select a UE in the vicinity of the UE2 as the second UE.

[0080] Then, the system 100 includes the second ID in the first sensing information and transmits it to the UE2.

[0081] <UE's operation> First, the UE2 transmits a request for obtaining information including the position and moving direction of the object to be detected to the system 100 (core network). The UE2 transmits a request message for making a request (Request) for sensing data to the SENSING11m via the AF12 included in the system 100. Note that the acquisition request may not include a request for information regarding the position of the object. It does not have to include a request for the information regarding the position of the object.

[0082] Next, the UE2 obtains, from the system 100 (core network), first sensing information that is the sensing result of the object to be detected and includes the moving direction of the object to be detected. The first sensing information includes information corresponding to the area where the object exists, the shape of the object, the moving speed, a flag (UE ID) indicating the moving direction, and the like.

[0083] <Other variations> The above embodiments are merely examples, and the present disclosure can be appropriately modified and implemented without departing from the gist thereof.

[0084] In the above embodiment, the system 100 acquires the results of wireless sensing of the object to be sensed, but the system 100 may acquire the results of sensing of the object to be sensed by a UE other than the first terminal (UE2).

[0085] In the above embodiment, data is provided to the user terminal by a Request / Response method, but it may be provided by a Subscribe / Notify method.

[0086] The present disclosure can also be realized by supplying a computer program implementing the functions described in the above embodiments to a computer, and having one or more processors of the computer read and execute the program. Such a computer program may be provided to the computer by a non-transitory computer-readable storage medium connectable to the system bus of the computer, or may be provided to the computer via a network. Non-transitory computer-readable storage media include, for example, any type of disk, such as a magnetic disk (floppy disk, hard disk drive (HDD), etc.), an optical disk (CD-ROM, DVD disk, Blu-ray disk, etc.), a read-only memory (ROM), a random access memory (RAM), an EPROM, an EEPROM, a magnetic card, a flash memory, an optical card, and any type of medium suitable for storing electronic instructions.
