[0010] Consider the following situation: a request is received from a user terminal, the position and direction of travel of the user terminal are detected, and information including the position and direction of travel of the user terminal is notified to the user terminal. As an example, the user terminal is a mobile communication terminal. In such a system, the user terminal sometimes wants to obtain not only its own position and direction of travel, but also the position and direction of travel of other objects other than itself. As an example, other objects other than the user terminal may be other mobile communication terminals other than the user terminal. For example, in order to move safely, the user terminal sometimes wants to obtain the direction of travel of an object that is on its own path of travel. Therefore, the preferred system not only detects the position and direction of travel of the user terminal that sent the request and notifies the user terminal, but also detects the position and direction of travel of any object specified by the user terminal and notifies the user terminal.

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

[0012] An example of a wireless communication network is 5G, 4G, LTE, LTE-A, SUPER3G, IMT-Advanced, NR, other systems, and next-generation systems based on these systems. In addition, other examples of wireless communication networks are IEEE802.11 (Wi-Fi (registered trademark)), IEEE802.16 (WiMAX (registered trademark)), IEEE802.20, UWB, Bluetooth (registered trademark), other systems, and next-generation systems based on these systems. A wireless communication network may also be a system composed of a plurality of systems.

[0013] The object to be detected is typically a mobile communication terminal other than a user terminal. Of course, the object to be detected may not be a mobile communication terminal. The object to be detected may also be any object without a communication function.

[0014] The direction of travel refers to the direction in which an object is moving when it is moving from one location to another. The direction of travel can be expressed in terms of east, west, south, north, or azimuth.

[0015] As a result, the system involved in the present disclosure can notify the UE (terminal) of the moving direction of the object for which there is an inquiry.

[0016] In addition, the acquisition request may also include the ID of the first terminal which is a terminal connected to the wireless communication network, that is, the first ID, and the processor, based on the first ID, includes the travel direction of the object to be detected, which is determined based on the travel direction of the first terminal, in the first perception information and sends it.

[0017] Thus, the system involved in the present disclosure can relatively identify the direction of travel between the object as the detection object and the UE. Therefore, the system involved in the present disclosure can determine the direction of travel of the object as the detection object based on the direction relative to the direction of travel of the UE that sent the perception request.

[0018] In addition, the processor may determine whether the first terminal and the object to be detected have the same moving direction based on the first ID, and include the determination result in the first perception information as information indicating the moving direction and send it.

[0019] Thus, the system involved in the present disclosure can identify whether the object to be detected and the UE are moving in the same direction. Therefore, the system involved in the present disclosure can relatively determine the moving direction of the object to be detected based on the moving direction of the UE that sent the perception request.

[0020] In addition, the processor may include the ID of the second terminal having the same travel direction as the travel direction of the object, that is, the second ID, in the first perception information as information indicating the travel direction and send it.

[0021] Therefore, the system involved in the present disclosure can provide information related to the ID of the UE that has the same moving direction as the object to be detected.

[0022] In addition, the processor may include the order in which the object to be detected is connected to a plurality of base stations as information indicating the traveling direction in the first perception information and send the information.

[0023] The UE (terminal) connected to the core network is connected to the nearest base station, but as the UE (terminal) moves, the base station it is connected to also changes. Therefore, when the object to be detected is an object connected to the core network, the direction of travel of the object to be detected can be inferred based on the connection history between the object to be detected and the base station.

[0024] Therefore, the system involved in the present disclosure can determine the moving direction of the object to be detected based on the connection history between the object to be detected and the base station.

[0025] In addition, the terminal involved in the present disclosure executes: sending a request for obtaining information representing the moving direction of the object as the detection object to the core network; and obtaining the perception result of the object as the detection object, i.e., the first perception information, from the core network, which includes the moving direction of the object as the detection object.

[0026] Therefore, the terminal involved in the present disclosure can achieve the same effect as the above-mentioned system.

[0027] Hereinafter, specific embodiments of the present disclosure will be described based on the accompanying drawings. 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 the configuration, unless otherwise specified. For example, the following describes an example in which the present disclosure is applied to a fifth-generation mobile communication system, but the present disclosure can also be applied to mobile communication systems after the fourth or fifth generation. In addition, the present disclosure can also be applied to a mobile communication system specified by a method other than 3GPP (registered trademark), and can also be applied 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 utilized by the user terminal is perception data measured by the user terminal. However, the data provided and utilized can also be perception data measured by a device other than the user terminal, or can be any data other than perception data.

[0028] (Implementation Method) Figure 1 It represents the components (constituent elements) that make up the fifth generation mobile communication system (5G network). Figure 1 In the figure, UE (User Equipment) 2 is the terminal of the user (subscriber). RAN (Radio Access Network) 3 is the access network to the 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 UE 2, DN 5 and AF 12 are connected in the 5G network. NF 11a~11m are functions implemented by executing programs by one or more computers (information processing devices). However, more than two of NF 11a~11m can also be implemented by a single computer. NF 11a~11m can also be called a network node or a network component. Figure 1 The components (constituent elements) shown realize the system 100 according to the embodiment.

[0029] 5GC is composed of a collection of components with specified functions called NF (Network Function). Figure 1 In FIG. 5 , NF 11 constituting 5GC is shown as follows. Figure 1 In FIG. 1 , a plurality of elements constituting NF 11 are indicated by bold 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 data packets (data packets on the user plane sent / received by the UE 2), packet inspection, and QoS processing.

[0032] AMF 11b is an on-network accommodation device for UE in 5GC. AMF 11b accommodates RAN 3, performs subscriber authentication control, and manages the location (mobility) of UE 2.

[0033] SMF 11c controls UPF 11a to manage PDU (Protocol Data Unit) sessions, implement QoS (Quality of Service) control and policy control. PDU sessions are virtual communication lines used to access data between UE 2 and DN (Data Network) 5. DN 5 is a data network (such as the Internet) outside 5GC.

[0034] PCF 11d performs QoS control, policy control, and fee control under the control of SMF 11c. In QoS control, communication quality control such as priority forwarding of packets is performed. In policy control, communication control such as QoS, packet forwarding permission, and fee deduction is performed based on network or subscriber information.

[0035] NEF 11e implements the function of mediating the communication between external nodes and nodes in the control plane.

[0036] NRF 11g stores and manages information of NFs (such as AMF, SMF, UPF, etc.) within 5GC. NRF 11g can respond to inquiries about the NFs that the user wishes to use by providing multiple NF candidates to the inquiring party.

[0037] The NSSF 11h has a function of selecting a network slice to be used by a subscriber from among network slices generated by network segmentation. A network slice is a virtual network having specifications according to the usage.

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

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

[0040] The NWDAF 11k has a function of collecting and analyzing data from each NF 11, an external server, etc. It is an NF that provides analysis information of the network.

[0041] SENSING 11m implements a sensing service, which includes collecting sensing information from UE 2, RAN 3 (base station (gNB)) or other nodes, and providing the collected sensing information to UE 2 or other external systems (AF 12, DN 5, etc.). The details of SENSING 11m are described later.

[0042] AF 12 is an NF that provides application services via NRF 11g as part of 5GC, or an NF that is located outside 5GC and provides application services via NEF 11e. AF 12 performs processing using sensing data, for example. As an example, AF12 notifies UE (terminal) of information indicating the position and direction of travel of an object to be detected, which is obtained by SENSING 11m. In addition, the position may not be included in the information. In addition, an application executed in the UE (terminal) may also act as AF 12.

[0043] In 5GC, multiple NFs of the same type are sometimes prepared. For example, NF 11 is sometimes prepared for each data center (building). In addition, one NF 11 is sometimes shared between data centers. In addition, multiple NFs of the same type are sometimes configured by one data center. The number of data centers and the number of NFs 11 can be appropriately set according to the correspondence between NFs 11 and data centers.

[0044] <Configuration of information processing device and terminal> Figure 2A FIG. 2 is a diagram showing a configuration example of an information processing device 20 that can operate as the system 100 according to the embodiment. Figure 2A In the embodiment, the information processing device 20 can be formed by using a dedicated or general-purpose information processing device (computer) such as a personal computer (PC), a workstation (WS) or a server. Of course, the information processing device 20 can also be a collection of one or more computers (cloud).

[0045] The information processing device 20 includes a processor 21 as a processing unit or a control unit (controller), a storage device 22 , a communication interface 23 (communication IF 23 ), an input device 24 , and a display 25 , which are connected to each other via a bus 26 .

[0046] The storage device 22 includes a main storage device and an auxiliary storage device. The main storage device is used as at least one of a storage area for programs and data, an opening area for programs, an operation area for programs, and a cache area for communication data. The main storage device is composed of a RAM (Random Access Memory) or a combination of RAM and ROM (Read Only Memory). The auxiliary storage device is used as a storage area for data and programs. A non-volatile storage medium is used as an auxiliary storage device. Non-volatile storage media are, for example, hard disks, solid state drives (SSDs), flash memories, or EEPROMs (Electrically Erasable Programmable Read-Only Memory). In addition, the storage device 22 may include a drive device for a disk storage medium.

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

[0048] The input device 24 includes keys, buttons, pointing devices, and touch panels, etc., for inputting information. The display 25 is, for example, a liquid crystal display, etc., for displaying 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 the NFs 11a to 11m and the external servers 12a and 12b. The processor 21 is a specific example of the control unit of the system 100.

[0050] Figure 2B 4 is a diagram showing an example of a configuration of a terminal 40 that can operate 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 that are connected to each other via a bus 46. The processor 41, the storage device 42, the communication IF 43, the input device 44, and the display 45 can use the same components as the processor 21, the storage device 22, the communication IF 23, the input device 24, and the display 25. Therefore, the description of these components is omitted.

[0051] Processors 21 and 41 are, for example, central processing units (CPUs). CPUs are also called microprocessor units (MPUs). Processors 21 and 41 may be composed of a single processor or multiple processors. In addition, a single physical CPU connected via a single socket may also have a multi-core structure. Processors 21 and 41 may also include computing devices composed of various circuits such as digital signal processors (DSPs) or graphics processing units (GPUs). In addition, processors 21 and 41 may also have a structure that works in conjunction with at least one of an integrated circuit (IC), other digital circuits, and analog circuits. Integrated circuits include LSIs, application specific integrated circuits (ASICs), and programmable logic devices (PLDs). PLDs include, for example, field programmable gate arrays (FPGAs). Processors 21 and 41 may also include components called microcontrollers (MCUs), SoCs (System-on-a-chip), system LSIs, or chipsets.

[0052] <System Operation> Figure 3 It is a timing diagram related to the perception processing performed by the control unit of the system involved in the embodiment. In addition, the timing diagram shown here is an example, and can include processing other than the diagram, or can omit part of the processing shown in the diagram, and can also change the execution order of the processing shown in the diagram.

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

[0054] In step S10, the UE 2 requesting the perception of the object sends a request message (Request) for sensing data to the SENSING 11m. The request message contains parameters for determining the object to be detected. The parameters for determining the object to be detected may, for example, represent the area where the object to be detected exists, the shape of the object to be detected, the moving speed, and a flag indicating the notification method of the traveling direction. The first example of the notification method is a method in which the ID of the specified 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. As an example of a notification method based on the traveling direction of the specified UE, it is envisaged that there is a method of notifying whether the specified angle is the same as or different from the traveling direction, the same as or opposite to the traveling direction, etc. based on the traveling direction of the specified UE. The second example of the notification method is a method of notifying using the service area of ​​the base station. By notifying at least two base stations, it is possible to grasp in which direction the object to be detected is moving. The third example of the notification method is a method of notifying the ID of other UEs with the same traveling direction as the object to be detected. A fourth example of a notification method is a method of specifying the direction of travel of an object to be detected by an azimuth angle. UE 2 includes a parameter indicating which notification method is desired for notifying sensing data in a request message and sends the request message. In addition, UE 2 may also send a request message to SENSING 11m via AF 12.

[0055] In step S11, SENSING 11m obtains the result of sensing the object as the detection object (sensing information). For example, SENSING 11m sends a data request message to the base station or other UEs other than UE 2. The data request message also includes parameters for determining the object as the detection object. The parameters for determining the object as the detection object are the same as those in the above request message.

[0056] SENSING 11m may also obtain the result of wireless sensing performed by the base station on the object to be sensed. In addition, SENSING 11m may also communicate with other UEs other than UE 2 to obtain the result of wireless sensing performed by the other UEs on the object to be sensed.

[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 UEID of the object to be detected.

[0058] In step S13, the NWDAF 11k sends a mobility response including statistical information corresponding to the UEID of the object to be detected, etc. The mobility response includes the result of analyzing the moving direction of the object to be detected. The moving direction of the object to be detected can also be expressed as a handover record of the connection between the object to be detected and the base station.

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

[0060] Next, the processing executed by the control unit of the system 100 according to the embodiment will be described. Figure 4 is a flowchart related to the sensing process performed by the control unit of the system involved in the embodiment. Figure 4 The described processing can be executed by the processor 41 of the information processing device 20 that can operate as the system 100 .

[0061] First, in step S20, the control unit receives a request for obtaining the position and moving direction of the object to be detected from UE 2. The control unit receives a request message from UE 2, which indicates the area where the object to be detected exists, the shape of the object to be detected, the moving speed of the object to be detected, and the moving direction of the object to be detected, for which information related to the object to be detected is requested. In addition, the acquisition request may not include the acquisition request for the position of the object to be detected.

[0062] Next, in step S21, SENSING 11m obtains the result of sensing the object as the detection target (sensing information). For example, SENSING 11m can communicate with the base station to obtain the result of wireless sensing of the object as the detection target by the base station. In addition, SENSING 11m can also communicate with other UEs other than UE 2 to obtain the result of wireless sensing of the object as the detection target by the other UEs.

[0063] Next, in step S22, the SENSING 11m determines the moving direction of the object as the detection target based on the sensing result of the object as the detection target. The process of determining the moving direction of the object as the detection target by the SENSING 11m is as follows: Figure 5 and Figure 6 Describe in detail.

[0064] Next, in step S23, the control unit sends the first perception information to UE 2. Here, the first perception information refers to information indicating the result obtained after the object as the detection object is perceived, and may include the area where the object as the detection object exists, the shape of the object as the detection object, the moving speed of the object as the detection object, and the moving direction information of the object as the detection object. The control unit obtains the result obtained after the wireless perception of the object as the detection object, and sends information including the position and moving direction of the object to UE 2. In addition, the first perception information may not include the position of the object as the detection object.

[0065] There are many ways to express the direction of travel information included in the first perception information. The first example is to express the direction of travel based on the UE (first terminal) included in the request message. For example, the direction of travel of the object to be detected can be expressed as being the same as or opposite to the first terminal, or it can also be expressed as an angle based on the moving direction of the first terminal. The second example is to express the direction of travel of the object to be detected using at least two base stations. In this case, the direction of travel can be determined as the direction from the first base station cell toward the second base station cell. In the second example, the handover history of the object to be detected can be directly included in the first perception information. The third example is a method of expressing the direction of travel of the object to be detected using a UE having the same direction of travel as the object to be detected. The fourth example is a method of expressing the direction of travel of the object to be detected in directions such as east, west, south, and north or in azimuth.

[0066] Figure 5 This is a flowchart of a process executed by the control unit of the system 100 involved in the embodiment to determine the traveling direction of an object based on the order of connection with the base station. For example, the system 100 can determine the traveling direction of the object as the detection target based on the connection history between the object as the detection target and the base station. In addition, the method for determining the traveling direction of the object as the detection target is not limited to this.

[0067] First, in step S30, the control unit obtains the order in which the object to be detected is connected to the base station. In step S31, the control unit determines the direction of travel of the object to be detected based on the connection order of the base stations obtained. In the case where the object to be detected is an object connected to the base station through wireless communication, the control unit obtains the connection history between multiple base stations and determines which of the multiple base stations the object to be detected is connected to in sequence. The object to be detected is connected to the base station near the area where it is located at each time as it moves, so the direction in which the base stations are arranged in the order of connection with the object to be detected can be determined as the direction of travel of the object. Specifically, SENSING 11m can obtain statistical information associated with the UEID of the object to be detected from NWDAF 11k. The statistical information includes the handover history of the object to be detected.

[0068] In addition, the method for determining the moving direction of the object to be detected is not limited to this. The control unit can also determine the moving direction of the object to be detected based on the history of the detection position of the object to be detected. In this case, the moving direction of the object to be detected is represented by an azimuth, for example.

[0069] Figure 6 1 is a schematic diagram showing a situation where the first terminal of the system involved in the embodiment is connected to multiple base stations. The object to be detected (e.g., any UE 3) sequentially connects to the base stations corresponding to the respective cells in which it is located as it moves. The system 100 has a function of determining the relative direction between the UE (terminal) that has sent a request for sensing the object to be detected and the object to be detected. Therefore, the system 100 can relatively infer the direction of travel of the object to be detected based on the direction of travel of the object to be detected and the UE (terminal) that has sent a request for sensing.

[0070] Specifically, if Figure 6 As shown, UE 3 is first connected to base station 500A. Then, as UE 3 moves, UE 3 releases the connection with base station 500A and connects to base station 500B. In addition, as UE 3 further moves, UE 3 releases the connection with base station 500B and connects to base station 500C.

[0071] In this way, UE 3 is sequentially connected to each of the plurality of base stations. Then, system 100 can relatively estimate the moving direction of the object to be detected based on the moving direction of UE 3 estimated from the connection history with the plurality of base stations.

[0072] The control unit of the system 100 may notify the moving direction of the object to be detected through the azimuth angle, or may notify the moving direction of the object to be detected through the order of the connected base stations.

[0073] There are a number of methods for notifying the moving direction of the object to be detected, and each method will be described below.

[0074] Figure 7 This is a flowchart showing the processing of the control unit of the system 100 according to the embodiment when notifying the moving direction of the object to be detected 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 obtains the travel direction of the first terminal and the object as the detection object. In step S40, the travel direction of the first terminal and the travel direction of the object as the detection object can be obtained separately, or the relative travel direction of the first terminal and the object as the detection object can be obtained. Each travel direction can be obtained by the above method. The relative travel direction can be obtained, for example, by the method specified in TS23.273 6.20.

[0076] In step S41, the control unit expresses the moving direction of the object to be detected based on the moving direction of the first terminal. As an example, the control unit can determine whether the moving direction of the object to be detected is the same direction as or opposite to the moving direction of the first terminal, or can determine the angle of the moving direction of the object to be detected based on the moving direction of the first terminal. In step S42, the first perception information representing the moving direction information of the object to be detected is generated, and the first perception information is included in the perception response and sent to UE 2.

[0077] Figure 8 This is a schematic diagram of processing when notifying using other UEs that have the same traveling direction as the object to be detected. For example, when notifying the traveling direction of the object to be sensed, the system 100 can use the ID (second ID) of other UEs that have the same traveling direction as the object to be detected for notification.

[0078] First, UE 2 sends a request message for sensing data to system 100. Then, system 100 obtains the moving direction of object 300 as the object to be detected, etc.

[0079] Next, the system 100 detects another UE (second UE) traveling in the same direction as the traveling direction of the object 300, and obtains its UEID. This UEID is referred to as the second ID. Preferably, the traveling direction of the second UE is known to UE 2. Thus, UE 2 may notify the system 100 of the candidates for the second UE in advance, and the system 100 may select the second UE from these candidates. Alternatively, the system 100 may also assume that UE 2 has grasped the traveling direction of the UE near UE 2, and select the UE near UE 2 as the second UE.

[0080] Then, the system 100 includes the second ID in the first perception information and sends it to the UE 2.

[0081] <UE Action> First, UE 2 sends a request to obtain information indicating the position and direction of travel of the object to be detected to system 100 (core network). UE 2 sends a request message to SENSING 11m to request sensing data via AF 12 included in system 100. In addition, the request to obtain information related to the position of the object to be detected may not be included.

[0082] Next, UE 2 obtains the first perception information, which is the perception result of the object to be detected and indicates the moving direction of the object to be detected, from system 100 (core network). The first perception information includes information such as the area where the object to be detected exists, the shape of the object to be detected, the moving speed, and the flag (UEID) indicating the moving direction.

[0083] <Other Modifications> The above-described embodiment is merely an example, and the present disclosure can be implemented with appropriate modifications without departing from the gist of the disclosure.

[0084] In the above embodiment, the system 100 obtains the result of wireless sensing of the object as the sensing target, but the first terminal (UE 2) may obtain the result obtained by sensing the object as the sensing target through other UEs.

[0085] In the above-mentioned embodiment, the provision of data to the user terminal is performed by a request / response method, but it may also be performed by a subscription / notification method.

[0086] The present disclosure can also be implemented in the following manner: that is, a computer program with the functions described in the above-mentioned embodiment installed is provided to a computer, and the program is read and executed by one or more processors of the computer. Such a computer program can be provided to a computer via a non-temporary computer-readable storage medium that can be connected to the system bus of the computer, or it can be provided to the computer via a network. Non-temporary computer-readable storage media include any type of disks such as magnetic disks (floppy disks (registered trademark), hard disk drives (HDDs), etc.), optical disks (CD-ROMs, DVD disks, Blu-ray disks, etc.), read-only memories (ROMs), random access memories (RAMs), EPROMs, EEPROMs, magnetic cards, flash memories, optical cards, and any type of media suitable for storing electronic instructions.
