[0031] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. In this specification and drawings, elements that can be similarly described will be designated by the same reference numerals, and redundant description may be omitted.

[0033] <<1. System Configuration>> An example of the configuration of a system 1 according to an embodiment of the present disclosure will be described with reference to Figures 1 to 3. Figure 1 is an explanatory diagram showing an example of a schematic configuration of a system 1 according to an embodiment of the present disclosure. Referring to Figure 1, the system 1 includes a core network (CN) 10, a control device 100, a radio station 500, and a mobile terminal 600. Naturally, the system 1 may include multiple radio stations 500, or multiple mobile terminals 600.

[0034] For example, the system 1 is a mobile communication system that complies with the technical specifications (TS) of the Third Generation Partnership Project (3GPP). More specifically, the system 1 may comply with the technical specifications (TS) of the fifth generation (5G) / New Radio (NR). Of course, the system 1 is not limited to these examples.

[0035] (1) Core Network (CN) 10 The CN 10 includes a plurality of core network (CN) nodes, each of which may be referred to as a network function (NF). For example, as shown in FIG. 1, the CN 10 includes a first CN node 200, a second CN node 300, and a third CN node 400.

[0036] For example, the first CN node 200 manages at least one of access and mobility of the mobile terminal 600. The second CN node 300 is used by devices located outside the CN 10 (e.g., application functions (AFs)) to interact with the CN 10. The third CN node 400 manages sessions for the mobile terminal 600.

[0037] Referring to Figure 2, which shows a more specific example, for example, CN10 is a 5G core network (5GC), the first CN node 200 is an AMF (Access and Mobility Management Function), the second CN node 300 is an NEF (Network Exposure Function), and the third CN node 400 is an SMF (Session Management Function).

[0038] Naturally, the first CN node 200, the second CN node 300, and the third CN node 400 are not limited to the above examples. Naturally, the CN10 may further include one or more CN nodes other than the first CN node 200, the second CN node 300, and the third CN node 400. Furthermore, the CN10 may include a plurality of first CN nodes 200, a plurality of second CN nodes 300, or a plurality of third CN nodes 400. Furthermore, as the mobile terminal 600 moves, the first CN node 200 that manages the mobile terminal 600 may be updated to another first CN node 200. Similarly, as the mobile terminal 600 moves, the third CN node 400 that manages the session of the mobile terminal 600 may be updated to another third CN node 400.

[0039] (2) Radio Station 500 The radio station 500 is a node of a Radio Access Network (RAN) and communicates with mobile terminals (e.g., mobile terminal 600) located within the cell or coverage area of the radio station 500. For example, the radio station 500 communicates with the mobile terminal using radio resources allocated to the mobile terminal.

[0040] Referring to FIG. 2 for a more specific example, for example, the radio station 500 is an NG-RAN (Radio Access Network) node. As defined in 5G TSs (e.g., TS 38.300, TS 38.401), the NG-RAN node may be a gNB or an ng-eNB, or a node with another name defined in the TS. The gNB is a node that provides termination of at least one of NR user plane and control plane protocols for a UE (User Equipment) and is connected to a 5GC via an NG interface. The ng-eNB is a node that provides termination of at least one of E-UTRA (Evolved Universal Terrestrial Radio Access) user plane and control plane protocols for a UE and is connected to a 5GC via an NG interface. Two NG-RAN nodes may be directly connected to each other via an Xn interface.

[0041] The radio station 500 may include multiple units (or multiple nodes). The multiple units (or multiple nodes) may include a first unit (or first node) that processes an upper protocol layer and a second unit (or second node) that processes a lower protocol layer. As an example, the first unit may be called a central unit (CU), and the second unit may be called a distributed unit (DU). For example, the first unit (central unit) may process a radio resource control (RRC) layer, a service data adaptation protocol (SDAP) layer, and a packet data convergence protocol (PDCP) layer. Furthermore, the second unit (distributed unit) may process a radio link control (RLC) layer, a medium access control (MAC) layer, and a physical layer (PHY).

[0042] Alternatively, the wireless station 500 may be a single unit (or a single node). In this case, the wireless station 500 may be one of the plurality of units (e.g., one of the first unit and the second unit) and may be connected to another unit of the plurality of units (e.g., the other of the first unit and the second unit).

[0043] (3) Mobile Terminal 600 and Control Device 100 The mobile terminal 600 communicates with the wireless station 500. For example, the mobile terminal 600 communicates with the wireless station 500 when it is located in the cell or coverage area of the wireless station 500. For example, the mobile terminal 600 communicates with the wireless station 500 using radio resources allocated to the mobile terminal 600.

[0044] In particular, the mobile terminal 600 can fly, and the control device 100 plans the flight of the mobile terminal 600. For example, the control device 100 determines a flight path for the mobile terminal 600, and the mobile terminal 600 moves along that flight path. The control device 100 may also communicate with the mobile terminal 600 during flight and control the flight of the mobile terminal 600. Communication between the control device 100 and the mobile terminal 600 may be performed as communication of user data, i.e., User Plane (UP) data, or as control signaling, i.e., Control Plane (CP) signaling. These communications may be performed via (i.e., terminated as appropriate) predetermined nodes of a core network (CN) and a radio access network (RAN).

[0045] In particular, the mobile terminal 600 may be a manned aircraft, also referred to as a PAV (Passenger Air Vehicle) or a manned aircraft, capable of flying using a wireless communication network (e.g., a wireless communication network using the 3GPP standard).

[0046] For example, the control device 100 generates flight path information for the mobile terminal 600 or acquires it from another device. Information including all or part of the flight path information may be called a flight plan, a flight profile, or the like. Alternatively, the flight path information itself may be called a flight plan, a flight profile, or the like. The flight path information includes route information (e.g., information indicating the positions of one or more waypoints) indicating the flight path of the mobile terminal 600. The position of each of the one or more waypoints may be expressed as latitude, longitude, and altitude. The flight path information may include movement speed information indicating the movement speed (velocity) of the mobile terminal 600. The movement speed information may indicate the horizontal movement speed (horizontal velocity) of the mobile terminal 600 and the vertical movement speed (vertical velocity) of the mobile terminal 600. The flight path information may further include other information, such as time information indicating the time for the flight of the mobile terminal 600. The time information may indicate the time at which the mobile terminal 600 passes through each of one or more waypoints. Additionally or alternatively, the time information may indicate the flight time of the mobile terminal 600 in one or more sections, each of which may be a section between any two waypoints. The mobile terminal 600 moves according to the flight path information. The flight path information may include information indicating a list of cells used in the flight of the mobile terminal 600.

[0047] 3 is an explanatory diagram illustrating an example of movement of a mobile terminal 600 in accordance with flight path information. Referring to FIG. 3, the mobile terminal 600 moves (i.e., flies) from a departure point 20 to a destination point 30 along a flight path 40. The flight path 40 overlaps with the cells 50 of each of a plurality of wireless stations 500, and the mobile terminal 600 can communicate (e.g., with the control device 100) via these wireless stations 500 when moving along the flight path 40. That is, the mobile terminal 600 can communicate (e.g., with the control device 100) using a plurality of cells 50 when moving along the flight path 40.

[0048] 3, the mobile terminal 600 uses one cell for each wireless station 500 when moving along the flight path 40, but the aspects of the present disclosure are not limited to such an example. The flight path 40 may overlap with two or more cells of a certain wireless station 500, and the mobile terminal 600 may communicate using the two or more cells when moving along the flight path 40. The two or more cells may be cells in different areas (e.g., cells in different sectors) or may be cells in different frequency bands.

[0049] 2 showing a specific example, for example, the mobile terminal 600 is a UE (User Equipment). In particular, the mobile terminal 600 may be called an Aerial UE. For example, the mobile terminal 600 may be a flying device (e.g., a drone or a UAV) or a communication device attached to the flying device.

[0050] The control device 100 is located outside the CN 10. For example, the control device 100 is an application function (AF).

[0051] The above describes an example of the configuration of the system 1 according to the embodiment of the present disclosure. The above-described system 1 is particularly a system according to the first to fourth embodiments described below, but may also be a system according to other embodiments (fifth to ninth embodiments).

[0053] <2.1. Control equipment configuration> 4 is a block diagram showing an example of a schematic configuration of the control device 100 according to an embodiment of the present disclosure. Referring to FIG. 4, the control device 100 includes a network communication unit 110, a storage unit 120, and a processing unit 130.

[0054] (1) Network communication unit 110 The network communication unit 110 receives signals from a network and transmits signals to a network.

[0055] (2) Storage section 120 The memory unit 120 temporarily or permanently (non-temporarily) stores programs and parameters, as well as various data, for the operation of the control device 100. The programs include one or more instructions for the operation of the control device 100.

[0056] (3) Processing unit 130 The processing unit 130 provides various functions of the control device 100. The processing unit 130 includes a control unit 131 and a communication processing unit 133. The processing unit 130 may further include other components in addition to these components. That is, the processing unit 130 may perform operations other than those of these components. The specific operations of the control unit 131 and the communication processing unit 133 will be described in each aspect.

[0057] For example, the processing unit 130 (communication processing unit 133) communicates with other network nodes (for example, core network nodes) via the network communication unit 110.

[0058] (4) Implementation example The network communication unit 110 may be implemented by a network adapter, a network interface card, a transmitter, a receiver, and / or a transceiver, etc. The storage unit 120 may be implemented by a memory (e.g., non-volatile memory and / or volatile memory) and / or a hard disk, etc. The processing unit 130 may be implemented by one or more processors. The control unit 131 and the communication processing unit 133 may be implemented by the same processor, or may be implemented separately by different processors. The memory (storage unit 120) may be included in the one or more processors, or may be located outside the one or more processors.

[0109] <<3. Overview of the Aspects>> An overview of an embodiment of the present disclosure will be described with reference to FIG.

[0110] Fig. 10 is an explanatory diagram for explaining an overview of the embodiment of the present disclosure. Referring to Fig. 10, five operations (operation 1100, operation 1200, operation 1300, operation 1400, and operation 1500) are performed in the entire embodiment of the present disclosure.

[0111] The first aspect is directed to operation 1100 (transmitting and receiving capability information indicating whether operation of a wireless station is supported) and operation 1200 (transmitting and receiving resource information regarding availability of wireless resources). The fifth aspect is directed to operation 1100 in a more generalized manner, and the sixth aspect is directed to operation 1200 in a more generalized manner.

[0112] The second aspect is an aspect of the operation 1300 (reservation of radio resources), and the seventh aspect is a more generalized aspect of the operation 1300.

[0113] The third aspect is an aspect of operation 1400 (initiating communication for flight), and the eighth aspect is a more generalized aspect of operation 1400.

[0114] The fourth aspect is an aspect of the operation 1500 (handover), and the ninth aspect is a more generalized aspect of the operation 1500.

[0115] All of the five operations shown in FIG. 10 may be combined, or some of the five operations may be combined. That is, all of the operations in the first to fourth aspects may be combined, or at least some of the operations in the first to fourth aspects may be combined. Conversely, one of the five operations shown in FIG. 10 may be independent of the other four of the five operations. As an example, the operation of the fourth aspect (operation 1500) may be independent of the operations of the first to third aspects (operations 1100 to 1400). For example, the operations in each aspect may be performed according to different (or independent) conditions, as follows:

[0116] For example, operation 1100 (transmitting and receiving capability information indicating whether operation of a wireless station is supported) and operation 1200 (transmitting and receiving resource information regarding availability of wireless resources) are not performed for each individual flight of mobile terminal 600, but are performed in advance for many flights planned in the future. For example, operation 1100 (transmitting and receiving capability information indicating whether operation of a wireless station is supported) may be performed at the time of initial setup or each time each device is started up.

[0117] For example, operation 1300 (reserving radio resources) may occur during planning of an individual flight of mobile terminal 600 .

[0118] For example, operation 1400 (initiate communication for flight) occurs at the start of a planned flight.

[0119] For example, operation 1500 (handover) occurs while mobile terminal 600 is in flight.

[0120] <<4. First Aspect>> Next, a first aspect of the present disclosure will be described with reference to FIGS.

[0121] (1) Sending and receiving capability information (1-1) Capabilities of radio station 500 The radio station 500 (first communication processing unit 543) transmits, to the first CN node 200, first capability information indicating whether the radio station 500 supports operation for flight management of a manned air vehicle capable of flying using a radio communication network (e.g., a radio communication network using the 3GPP standard). The first CN node 200 (communication processing unit 233) receives the first capability information from the radio station 500. For example, the first capability information may be information indicating whether each of various operations of the radio station 500 disclosed herein is supported. Specifically, the first capability information may be information indicating whether drone service is supported, or information indicating whether "CN initiated HO (Handover) support" is true. In another example, the first capability information may be information indicating whether a change in flight path of the mobile terminal 600 is supported, or information indicating whether an instruction or request for landing of the mobile terminal 600 or auxiliary information used to determine whether to land the mobile terminal 600 is supported. Also, for example, the first capability information may be information indicating whether the wireless station 500 can provide resource information regarding the availability of wireless resources for at least one time period.

[0122] For example, the first CN node 200 (communication processing unit 233) receives the capability information from each of the multiple wireless stations 500 corresponding to the first CN node 200.

[0123] For example, the wireless station 500 (first communication processing unit 543) transmits an NG SETUP REQUEST message including the above-mentioned first capability information to the first CN node 200. The first CN node 200 (communication processing unit 233) receives the NG SETUP REQUEST message from the wireless station 500.

[0124] As one example, the first capability information may indicate that the wireless station 500 is capable of providing the resource information. As another example, the first capability information may indicate that the wireless station 500 does not support operation of the wireless station 500 to perform flight management of a manned air vehicle capable of flying using a wireless communication network, or the first capability information may indicate that the wireless station 500 is not capable of providing the resource information.

[0125] The specific content of the resource information will be explained in detail later.

[0126] (1-2) Capability of the first CN node 200 For example, the first CN node 200 (communication processing unit 233) transmits second capability information to the radio station 500 indicating whether the CN node 200 supports operation for flight management of a manned aircraft capable of flying using a wireless communication network (e.g., a wireless communication network using the 3GPP standard). The radio station 500 (first communication processing unit 543) receives the second capability information from the first CN node 200. For example, the second capability information may be information indicating whether each of the various operations of the CN node 200 disclosed herein is supported. Specifically, the second capability information may be information indicating whether drone service is supported, or information indicating whether "CN initiated HO (Handover) support" is true. In another example, the second capability information may be information indicating whether a change in the flight path of the mobile terminal 600 is supported, or information indicating whether an instruction or request for landing of the mobile terminal 600, or auxiliary information used to determine whether to land the mobile terminal 600, is supported. Furthermore, for example, the second capability information may be information indicating whether the first CN node 200 supports a service related to resource information related to the availability of radio resources for at least one time period. Also, for example, the second capability information may be information indicating whether the first CN node 200 can provide resource information related to the availability of radio resources for at least one time period. Additionally, the second capability information may indicate whether the first CN node 200 can accept resource information from the wireless station 500 regarding the availability of radio resources for at least one time period.

[0127] The second capability information set by the first CN node 200 may be set taking into consideration the presence or absence of capabilities of the control device 100 constituting the system 1, the presence or absence of capabilities of the second CN node (NEF) 300, and the presence or absence of capabilities of the third CN node (SMF) 400. Each of the control device 100, the second CN node (NEF) 300, and the third CN node (SMF) 400 may notify the first CN node (AMF) 200 of its own capability information in advance, or the first CN node 200 may determine the capabilities of the system 1 by inquiring of the control device 100, the second CN node (NEF) 300, and the third CN node (SMF) 400. The capabilities of each device may be determined based on at least one of whether the device has the capability, whether the device has the capability temporarily at the time the capability is present, and whether the physical device managing the device or an instance of the device is connected to the first CN node 200.

[0128] For example, the first CN node 200 (communication processing unit 233) receives an NG SETUP RESPONSE message including the second capability information from the first CN node 200. The radio station 500 (first communication processing unit 543) receives the NG SETUP RESPONSE message from the first CN node 200.

[0129] As one example, the second capability information may indicate that the first CN node 200 can provide the resource information (e.g., to other CN nodes). As another example, the second capability information may indicate that the first CN node 200 does not support operation for flight management of a manned air vehicle capable of flying using a wireless communication network, or the second capability information may indicate that the first CN node 200 cannot provide the resource information (e.g., to other CN nodes).

[0130] The specific content of the resource information will be explained in detail later.

[0131] (1-3) Processing flow FIG. 11 is a sequence diagram illustrating an example of a schematic flow of a process for transmitting and receiving capability information according to the first aspect.

[0132] In FIG. 11, for clarity, as a specific example, the radio station 500 is described as an NG-RAN node, and the first CN node 200 is described as an AMF.

[0133] The NG-RAN node 500A transmits an NG SETUP REQUEST message including the first capability information to the AMF 200 (S1101).

[0134] In response to receiving the NG SETUP REQUEST message, the AMF 200 transmits an NG SETUP RESPONSE message to the NG-RAN node 500A (S1103). The NG SETUP RESPONSE message may include second capability information.

[0135] FIG. 11 shows an example of a sequence for capability negotiation between the NG-RAN node 500A and the AMF 200, but the respective capability information may be transmitted using the following messages.

[0136] For example, the first capability information of the NG-RAN node 500A may be transmitted to the AMF 200 in a RAN CONFIGURATION UPDATE message and / or an AMF CONFIGURATION UPDATE ACKNOWLEDGE message transmitted from the NG-RAN node 500A to the AMF 200. Furthermore, the second capability information of the AMF 200 may be transmitted to the NG-RAN node 500A in a RAN CONFIGURATION UPDATE ACKNOWLEDGE message and / or an AMF CONFIGURATION UPDATE message transmitted from the AMF 200 to the NG-RAN node 500A.

[0137] Furthermore, the first capability information of the NG-RAN node 500A may be notified to the NG-RAN node 500B. The first capability information of the NG-RAN node 500A may be transmitted to the NG-RAN node 500B in an XN SETUP REQUEST message transmitted from the NG-RAN node 500A to the NG-RAN node 500B and / or an NG-RAN NODE CONFIGURATION UPDATE message. Also, the first capability information of the NG-RAN node 500B may be notified to the NG-RAN node 500A. The first capability information of the NG-RAN node 500B may be transmitted to the NG-RAN node 500A in an XN SETUP RESPONSE message transmitted from the NG-RAN node 500B to the NG-RAN node 500A and / or an NG-RAN NODE CONFIGURATION UPDATE ACKNOWLEDGE message.

[0138] The NG-RAN node 500A may generate third capability information of the system 1 based on the first capability information of the NG-RAN node 500A and the second capability information of the AMF 200 connected to the NG-RAN node 500A. Here, the third capability information may be information indicating whether the system 1 supports operation for flight management of a manned air vehicle capable of flying using a wireless communication network (e.g., a wireless communication network using the 3GPP standard). Specifically, the third capability information may be information indicating whether drone service is supported, or information indicating whether "CN initiated HO (Handover) support" is true. In another example, the third capability information may be information indicating whether a change in flight path of the mobile terminal 600 is supported, or information indicating whether an instruction or request to land the mobile terminal 600 or auxiliary information used to determine whether to land the mobile terminal 600 is supported. The NG-RAN node 500A may broadcast the generated third capability information to the mobile terminal 600 in a System Information Block (SIB) using a Broadcast Control Channel (BCCH). Note that the third capability information may be transmitted as a control plane signal or as user plane data. When the NG-RAN node 500A is connected to multiple AMFs 200, the third capability information may be generated using the second capability information supported by at least one AMF 200.

[0139] The first capability information, the second capability information, and the third capability information may be treated as network slice information in the system 1. In this case, the capability to support a flying mobile terminal (or aerial UE or drone) may be associated with a unique value of NSSAI (Network Slice Selection Assistance Information). Alternatively, the capability to support a flying mobile terminal (or aerial UE or drone) may be associated with a unique value of Standardized SST (Slice / Service type), which is a subfield of NSSAI. In this case, the first capability information, the second capability information, and the third capability information are handled by information elements such as Requested NSSAI, Subscribed NSSAI, Configured NSSAI, and Allowed NSSAI.

[0140] The Requested NSSAI contains one or more Single-Network Slice Selection Assistance Information (S-NSSAI) that the UE sends to the network, and the Allowed NSSAI contains one or more S-NSSAI that the network allows to be used.

[0141] The Configured NSSAI includes one or more S-NSSAIs that have been indicated to the UE as applicable to one or more public land mobile networks (PLMNs). The Subscribed NSSAI includes an S-NSSAI based on subscriber information that indicates that the UE is subscribed to use a certain PLMN.

[0142] As with the NG-RAN node 500A, the NG-RAN node 500B and the NG-RAN node 500C also transmit and receive messages in the same manner (S1111, S1113, S1121, S1123).

[0143] In the example of Fig. 11, "NG-RAN node" may be replaced with "radio station", "AMF" may be replaced with "first CN node", and "NG SETUP REQUEST" and "NG SETUP RESPONSE" may each be replaced with "message".

[0144] In the example of FIG. 11, the transmission and reception of the first capability information (steps S1101, S1111, S1121) may be performed, but the transmission and reception of the second capability information (steps S1103, S1113, S1123) may not be performed.

[0145] (1-4) First Modified Example -First capability information As described above, for example, the first capability information may indicate whether the wireless station 500 supports operation for flight management of a manned air vehicle capable of flying using a wireless communication network (e.g., a wireless communication network using the 3GPP standard). However, the first capability information is not limited to this example.

[0146] The first capability information may indicate whether the radio station 500 supports a flying mobile terminal (or an aerial UE or a drone). Furthermore, if the radio station 500 supports a flying mobile terminal (or an aerial UE or a drone), the radio station 500 may be able to provide the resource information.

[0147] -Second capability information As described above, for example, the second capability information may indicate whether the first core network node 200 supports operation for flight management of a manned air vehicle capable of flying using a wireless communication network (e.g., a wireless communication network using the 3GPP standard). However, the second capability information is not limited to this example.

[0148] The second capability information may indicate whether the first CN node 200 supports a flying mobile terminal (or an aerial UE or a drone). Furthermore, if the first CN node 200 supports a flying mobile terminal (or an aerial UE or a drone), the first CN node 200 may be able to provide the resource information.

[0149] -Third Capability Information As described above, for example, the third capability information may indicate whether the system 1 supports operation for flight management of a manned air vehicle capable of flying using a wireless communication network (e.g., a wireless communication network using the 3GPP standard). However, the third capability information is not limited to this example.

[0150] The third capability information may indicate whether the system 1 supports a flying mobile terminal (or an aerial UE or a drone). Furthermore, if the system 1 supports a flying mobile terminal (or an aerial UE or a drone), the system 1 may be able to provide the resource information.

[0151] The transmission and reception of capability information according to the first aspect has been described above. When the first capability information is not transmitted from the radio station 500 to the first CN node 200, the first CN node 200 may request information for flight management (e.g., resource information) from the radio station 500, regardless of whether the radio station 500 supports operation for flight management of a manned air vehicle capable of flying using a wireless communication network (e.g., a wireless communication network using the 3GPP standard). Here, if the radio station 500 is unable to provide the information for flight management, the request for the information for flight management is wasted. Therefore, unnecessary signaling may occur when transmitting and receiving the information for flight management, resulting in wasted communication resources and processing resources of each node. On the other hand, when the first capability information is transmitted from the radio station 500 to the first CN node 200 as described above, the first CN node 200 may determine whether the radio station 500 supports operation for flight management of a manned air vehicle capable of flying using a wireless communication network (e.g., a wireless communication network using the 3GPP standard). This avoids the occurrence of unnecessary signaling, thereby avoiding the waste of communication resources and processing resources of each node.

[0152] Furthermore, if the second capability information is not transmitted from the first CN node 200 to the radio station 500, the radio station 500 can provide the first CN node 200 with information for flight management (e.g., resource information) regardless of whether the radio station 500 supports the operation of the first CN node 200 for flight management of a manned air vehicle capable of flying using a wireless communication network (e.g., a wireless communication network using the 3GPP standard). Here, if the first CN node 200 is unable to provide the information for flight management, the provision of the information for flight management by the radio station 500 is wasted. Therefore, communication resources and processing resources of each node may be wasted when transmitting and receiving the information for flight management. On the other hand, if the second capability information is transmitted from the first CN node 200 to the radio station 500 as described above, the radio station 500 can determine whether the radio station 500 supports the operation of the first CN node 200 for flight management of a manned air vehicle capable of flying using a wireless communication network (e.g., a wireless communication network using the 3GPP standard). This avoids the occurrence of unnecessary signaling, thereby avoiding the waste of communication resources and processing resources of each node.

[0153] Furthermore, if the third capability information is not transmitted from system 1 to mobile terminal 600, mobile terminal 600 will access system 1 regardless of whether system 1 supports flying mobile terminals. Therefore, even if mobile terminal 600 desires communication for flight, it will communicate with system 1 that does not support flying mobile terminals, resulting in a waste of communication resources, processing resources of each node, and the time required to connect to the desired system. On the other hand, as described above, if the third capability information is transmitted from system 1 to mobile terminal 600, mobile terminal 600 can determine whether system 1 supports flying mobile terminals. Therefore, connection to an undesired (unsupported) system 1 is avoided, thereby preventing the waste of communication resources and processing resources of each node.

[0154] The capability information may be referred to as support information. That is, the first capability information, the second capability information, and the third capability information may be referred to as first support information, second support information, and third support information, respectively. The capability information may be an information element (IE) with an arbitrary name. The information element may be explicit information or implicit information. For example, the first capability information may be an information element that explicitly indicates whether the radio station 500 can provide the information for flight management, or may be an information element that implicitly indicates whether the radio station 500 can provide the information for flight management. For example, the second capability information may be an information element that explicitly indicates whether the first CN node 200 can provide the information for flight management, or may be an information element that implicitly indicates whether the first CN node 200 can provide the information for flight management.

[0155] The above-described first capability information may be used, for example, by the CN node 200 to select a wireless station 500. The above-described second capability information may be used, for example, by the wireless station 500 to select a CN node 200.

[0156] (2) Sending and receiving resource information The wireless station 500 (first communication processing unit 543) transmits resource information regarding the availability of wireless resources for at least one time period. The at least one time period is at least one time period in the future. The control device 100 (communication processing unit 133) receives the resource information.

[0157] For example, the wireless station 500 (first communication processing unit 543) transmits the resource information to the first CN node 200.

[0158] (2-1) Resource Information -By time / by frequency band For example, the resource information is information about the availability of radio resources for each time period.

[0159] For example, the resource information is information about the availability of radio resources for each frequency band for at least one time period.

[0160] For example, the resource information is information about the availability of radio resources for each time and each frequency band.

[0161] For example, the resource information is information regarding the availability of radio resources for each time and each cell. The resource information and location information indicating the radio station 500 or the location covered by the cell may be transmitted to the first CN node 200. Information regarding transmission power may be transmitted to the first CN node 200 together with the resource information. The information regarding transmission power may be average transmission power, maximum transmission power, or the like. Information regarding transmission power and location information of the radio station 500 may be transmitted to the first CN node 200 together with the resource information.

[0162] The frequency band may be a component carrier (CC), or may be a bandwidth part (BWP) included in a CC, or may be a band including multiple CCs.

[0163] The resource information regarding the availability of the radio resources may indicate that the radio resources are available for use by a mobile terminal, that the radio resources are available for a radio station to secure, or that the radio resources are temporarily reserved by a radio station.

[0164] -Contents --First example As a first example, the resource information is information indicating whether the radio resource is available or not, i.e., the resource information indicates that the radio resource is available or that the radio resource is unavailable.

[0165] For example, the resource information indicates whether radio resources are available for each frequency band at each time. As an example, when target times are T1 and T2 and target frequency bands are F1, F2, and F3, the resource information indicates whether radio resources are available for each of the frequency bands F1, F2, and F3 at time T1, and further indicates whether radio resources are available for each of the frequency bands F1, F2, and F3 at time T2.

[0166] --Second example As a second example, the resource information may be information indicating the degree of availability of the radio resource. For example, the resource information indicates whether the availability of the radio resource is high, medium, or low.

[0167] For example, the resource information indicates the degree of availability of the radio resources for each time period and for each frequency band. As an example, when target times are T1 and T2 and target frequency bands are F1, F2, and F3, the resource information indicates whether the availability of the radio resources for each of the frequency bands F1, F2, and F3 at time T1 is high, medium, or low, and further indicates whether the availability of the radio resources for each of the frequency bands F1, F2, and F3 at time T2 is high, medium, or low.

[0168] In the above example, three levels (high, medium, and low) are defined as the availability levels of the radio resources. However, the availability levels of the radio resources are not limited to this example. Four or more levels may be defined as the availability levels of the radio resources. The availability levels may be represented, for example, by linear values ranging from 0 to 100, or by linear values ranging from -100 to 100. In addition to the above types, a special value may be used to indicate that the availability is unknown, abnormal, or irregular. The special value may be expressed, for example, by one bit as a flag. For example, if the availability level is represented from 0 to 100, the special value may be 101. For example, if the availability level is represented from -100 to 100, the special value may be 101 or -101.

[0169] (2-2) Transmission to the control device The resource information is transmitted from the first CN node 200 to the control device 100 which generates or obtains flight path information for the mobile terminal 600 .

[0170] More specifically, for example, the resource information is transmitted from the radio station 500 to the control device 100 via OAM (Operations, Administration and Maintenance). Also, for example, the resource information is transmitted from the radio station 500 to the first CN node 200 (e.g., AMF), from the first CN node 200 to the second CN node 300 (e.g., NEF), and from the second CN node 300 to the control device 100.

[0171] In this case, the first CN node 200 (communication processing unit 233) receives the resource information from the radio station 500 and transmits the resource information to the second CN node 300. The second CN node 300 (communication processing unit 333) receives the resource information from the first CN node 200 and transmits the resource information to the control device 100. The control device 100 (communication processing unit 133) receives the resource information from the second CN node 300.

[0172] The resource information may be transmitted in response to some trigger. Specific examples of triggers for transmitting the resource information include, but are not limited to, the following examples. -First example: Sending on request As a first example, the radio station 500 (first communication processing unit 543) transmits the resource information to the first CN node 200 in response to the request for the resource information.

[0173] For example, the control device 100 (communication processing unit 133) transmits a message requesting the resource information to the second CN node 300. The message requesting the resource information may be, for example, a Nnef_Radio_condition_request message, or a message defined by another name. The second CN node 300 (communication processing unit 333) transmits a message requesting the resource information to the first CN node 200 in response to the request for the resource information from the control device 100. The message requesting the resource information may be a Namf_Radio_condition_request message, or a message defined by another name. The first CN node 200 (communication processing unit 233) requests the resource information from the radio station 500 in response to the request for the resource information from the second CN node 300. At this time, the first CN node 200 (communication processing unit 233) may request the resource information from the radio station 500 by transmitting a RAN STATUS REQUEST message or a message defined by another name. In response to a request for the resource information from the first CN node 200, the radio station 500 (first communication processing unit 543) transmits the resource information to the first CN node 200. At this time, the radio station 500 may transmit a RAN STATUS RESPONSE message including the resource information or a message defined by another name.

[0174] For example, the first CN node 200 (control unit 231) determines whether the radio station 500 can provide the resource information based on the first capability information. If the radio station 500 can provide the resource information, the first CN node 200 (communication processing unit 233) transmits a message requesting the resource information to the radio station 500. On the other hand, if the radio station 500 cannot provide the resource information, the first CN node 200 (communication processing unit 233) may transmit a response message indicating a rejection of the request for the resource information to the second CN node 300. Furthermore, the second CN node 300 (communication processing unit 333) may transmit a response message indicating a rejection of the request for the resource information to the control device 100.

[0175] The above-described on-demand transmission allows, for example, the control device 100 to obtain resource information on demand.

[0176] -Second example: Periodic transmission As a second example, the radio station 500 (first communication processing unit 543) may periodically transmit the resource information to the first CN node 200.

[0177] For example, the control device 100 (communication processing unit 133) may transmit periodicity information indicating the period of transmission of the resource information to the second CN node 300. The periodicity information may be transmitted, for example, included in a Nnef_Radio_condition_request message, or may be transmitted in a message defined by another name. The second CN node (communication processing unit 333) may receive the periodicity information from the control device 100 and transmit the periodicity information to the first CN node 200. The periodicity information may be transmitted, for example, included in a Namf_Radio_condition_request message, or may be transmitted in a message defined by another name. The first CN node 200 (communication processing unit 233) may receive the periodicity information from the second CN node 300 and transmit the periodicity information to the radio station 500. The periodicity information may be transmitted, for example, included in a RAN STATUS REQUEST message, or may be transmitted in a message defined by another name. The radio station 500 (first communication processing unit 543) may receive the periodic information from the first CN node 200 and transmit the resource information to the first CN node 200 (communication processing unit 233) at the period indicated by the periodic information.

[0178] Periodic transmission as described above allows, for example, the control device 100 to obtain resource information without individual requests.

[0179] (2-3) Resource Information Target For example, the radio station 500 (first communication processing unit 543) receives target information indicating the target of the resource information, and transmits the resource information for the target indicated by the target information to the first CN node 200.

[0180] More specifically, for example, the control device 100 (communication processing unit 133) transmits the above target information to the second CN node 300. The above target information may be transmitted, for example, included in a Nnef_Radio_condition_request message, or may be transmitted, for example, included in a message defined by another name. The second CN node 300 (communication processing unit 333) receives the above target information from the control device 100 and transmits the above target information to the first CN node 200. The above target information may be transmitted, for example, included in a Namf_Radio_condition_request message, or may be transmitted, for example, included in a message defined by another name. The first CN node 200 (communication processing unit 233) receives the above target information from the second CN node 300 and transmits the above target information to the radio station 500. The above target information may be transmitted, for example, included in a RAN STATUS REQUEST message, or may be transmitted, for example, included in a message defined by another name. The radio station 500 (first communication processing unit 543) receives the above object information from the first CN node 200, and transmits the above resource information for the object indicated by the object information to the first CN node 200. The first CN node 200 (communication processing unit 233) receives the above resource information for the object from the radio station 500. The second CN node 300 (communication processing unit 333) receives the above resource information for the object from the first CN node 200. The control device 100 (communication processing unit 133) receives the above resource information for the object from the second CN node 300.

[0181] For example, the target indicated by the target information includes one or more times and / or one or more frequency bands. That is, the target information includes information indicating the one or more times and / or information indicating the one or more frequency bands. As an example, the target is times T1 and T2 and frequency bands F1, F2, and F3, as described above.

[0182] Furthermore, the target indicated by the target information may include the wireless station 500 or the cell of the wireless station 500. That is, the target information may include information for identifying the wireless station 500 or the cell of the wireless station 500 (for example, a cell ID (Cell Identity)).

[0183] According to the target information as described above, for example, the control device 100 can acquire desired resource information.

[0184] (2-4) Processing flow -Summary 12 is a first sequence diagram for explaining an example of a schematic flow of a process of transmitting and receiving resource information according to the first aspect. The first sequence diagram is a schematic sequence diagram.

[0185] In FIG. 12, for clarity, the radio station 500 is depicted as an NG-RAN node as a specific example.

[0186] Resource information regarding the availability of radio resources for at least one time period is transmitted from the NG-RAN node 500A to the control device 100 (S1201). The NG-RAN node 500A may execute the process of S1201 for each business operator (carrier).

[0187] Similar to the NG-RAN node 500A, the NG-RAN node 500B and the NG-RAN node 500C each transmit resource information to the control device 100 (S1203, 1205).

[0188] In the example of FIG. 12, "NG-RAN node" may be replaced with "wireless station."

[0189] -detail 13 is a second sequence diagram illustrating an example of a schematic flow of a process of transmitting and receiving resource information according to the first aspect, the second sequence diagram illustrating an example in which the resource information is transmitted in response to a trigger.

[0190] In FIG. 13, for ease of understanding, as a specific example, the radio station 500 is described as an NG-RAN node, the first CN node 200 is described as an AMF, the second CN node 300 is described as an NEF, the third CN node 400 is described as an SMF, and the mobile terminal 600 is described as a UE.

[0191] The control device 100 transmits an Nnef_Radio_condition_request message to the NEF 300, requesting resource information regarding the availability of radio resources for at least one time period (S1211). Geographical location information may be added to the Nnef_Radio_condition_request message. The geographical location information is GPS (Global Positioning System) information or information indicating waypoints (hereinafter referred to as waypoint information) for the flight of the mobile terminal 600. For example, the waypoint information is also GPS information.

[0192] In response to receiving the Nnef_Radio_condition_request message, the NEF 300 transmits a Namf_Radio_condition_request message requesting the resource information to the AMF 200 (S1213). If the Nnef_Radio_condition_request message includes geographical location information, the NEF 300 may transmit a Namf_Radio_condition_request message to the AMF 200 that manages the location (area) based on the location information. The Namf_Radio_condition_request message may include the geographical location information.

[0193] In response to receiving the Namf_Radio_condition_request message, the AMF200 transmits a RAN STATUS REQUEST message requesting the resource information to the NG-RAN node 500 (S1215). If the Namf_Radio_condition_request message includes geographical location information, the AMF200 may determine the NG-RAN node 500 to which the RAN STATUS REQUEST message is to be transmitted based on the location information. Note that the location information may include GPS information of multiple locations or information on multiple waypoints, and multiple NG-RAN nodes 500 may be identified. Note that the AMF200 may determine the NG-RAN node 500 to which the RAN STATUS REQUEST message is to be transmitted based on the capability information of the NG-RAN node 500 described above.

[0194] In response to receiving the RAN STATUS REQUEST message, the NG-RAN node 500 transmits a RAN STATUS RESPONSE message including the resource information to the AMF 200 (S1217).

[0195] In response to receiving the RAN STATUS RESPONSE message, the AMF 200 transmits a Namf_Radio_condition_response message including the resource information to the NEF 300 (S1219).

[0196] In response to receiving the Namf_Radio_condition_response message, the NEF 300 transmits a Nnef_Radio_condition_response message including the resource information to the control device 100 (S1221).

[0197] The control device 100 receives the Nnef_Radio_condition_response message and acquires the resource information.

[0198] The Nnef_Radio_condition_request message, Namf_Radio_condition_request message, and RAN STATUS RESPONSE message may include the target information (e.g., time information, frequency information, and / or cell ID). In this case, the resource information may be resource information about a target indicated by the target information (e.g., one or more times, one or more frequency bands, and / or one or more cells, etc.).

[0199] Furthermore, the Nnef_Radio_condition_request message, Namf_Radio_condition_request message, and RAN STATUS RESPONSE message may include the periodicity information. In this case, the transmissions in steps S1217, S1219, and S1221 may be performed periodically.

[0200] In the example of Figure 13, "NG-RAN node" may be replaced with "radio station," "AMF" may be replaced with "first CN node," "NEF" may be replaced with "second CN node," "SMF" may be replaced with "third CN node," and "UE" may be replaced with "mobile terminal." Also, each of the messages shown in Figure 13 may be replaced with "message."

[0201] (2-5) Second Modification As described above, the target may include the wireless station 500 or the cell of the wireless station 500, and the target information may include information for identifying the wireless station 500 or the cell of the wireless station 500 (for example, a cell ID). However, the target information is not limited to this example.

[0202] The target information may include location information indicating one or more locations, and the target may include one or more wireless stations 500 corresponding to the one or more locations. For example, the first CN node 200 may identify the one or more wireless stations 500 based on the location information. Then, the first CN node 200 may transmit a message requesting the resource information to the one or more wireless stations 500.

[0203] (2-6) Third Modification As described above, for example, the resource information is transmitted from the first CN node 200 to the second CN node 300. However, the transmission of the resource information is not limited to this example.

[0204] The resource information may be transmitted from the first CN node 200 to the third CN node 400 and from the third CN node 400 to the second CN node 300.

[0205] The first CN node 200 (communication processing unit 233) may transmit the above resource information to the third CN node 400, the third CN node 400 (communication processing unit 433) may receive the above resource information from the first CN node 200 and transmit the above resource information to the second CN node 300, and the second CN node 300 (communication processing unit 333) may receive the above resource information from the third CN node 400. In this way, the first CN node 200 (communication processing unit 233) may indirectly transmit the above resource information to the second CN node 300, and the second CN node 300 (communication processing unit 333) may indirectly receive the above resource information from the first CN node 200.

[0206] (2-7) Fourth Modification As described above, for example, the resource information is transmitted from the wireless station 500 to the control device 100 by signaling within the CN 10. However, the transmission of the resource information is not limited to this example.

[0207] The resource information may be transmitted from the wireless station 500 to the control device 100 via OAM (Operations, Administration and Maintenance). In this case, the control device 100 may be an OAM node.

[0208] FIG. 14 is a sequence diagram illustrating an example of a schematic flow of a process of transmitting and receiving resource information according to the fourth modified example of the first aspect.

[0209] In FIG. 14, for clarity, the radio station 500 is depicted as an NG-RAN node as a specific example.

[0210] The NG-RAN node 500 transmits resource information regarding the availability of radio resources for at least one time period to the control device 100 via OAM (S1231).

[0211] In the example of FIG. 14, "NG-RAN node" may be replaced with "wireless station."

[0212] The transmission and reception of resource information according to the first aspect has been described above. If the resource information is not transmitted to the control device 100, the control device 100 plans the flight of the mobile terminal 600 (for example, determines the flight path of the mobile terminal 600) without knowing whether wireless resources are likely to be available. This may make it difficult for the control device 100 to determine a flight path that will ensure wireless resources. On the other hand, if the resource information is transmitted to the control device 100 as described above, the control device 100 can know to some extent whether wireless resources are likely to be available, and therefore, it may become easier to determine a flight path that will ensure wireless resources. As a result, it may become easier to determine a flight path that ensures the flight of the mobile terminal 600 and the safety of the crew aboard the mobile terminal 600.

[0213] <<5. Second Aspect>> Next, a second aspect of the present disclosure will be described with reference to FIGS.

[0214] (1) Request for securing resources The control device 100 (communication processing unit 133) executes a procedure to request the wireless station 500 to reserve wireless resources for the mobile terminal 600 that moves according to the flight path information. For example, the control device 100 transmits a first request message to the wireless station 500 via OAM, requesting the reservation of the wireless resources, based on the flight path information. Also, for example, the control device 100 transmits the first request message to the CN 10 connected to the wireless station 500 that reserves the wireless resources, based on the flight path information. The following describes an example of the operation when the control device 100 transmits a first request message to the CN 10. An example of the operation when the control device 100 transmits a first request message to the wireless station 500 via OAM will be described in (5) Second Modification.

[0215] (1-1) Information included in the first request message - First identification information (identification information for the mobile terminal 600) For example, the first request message includes first identification information for identifying the mobile terminal 600. For example, the first identification information is a temporary UE ID.

[0216] - Secondary identification (flight identification) For example, the reservation of the radio resources is reservation of radio resources for the flight of the mobile terminal 600, and the first request message includes second identification information for identifying the flight of the mobile terminal 600. For example, the second identification information is a flight ID or flight number (for example, normalized for each mobile terminal 600). The second identification information is managed by the mobile terminal 600 and distributed to devices constituting the system 1. Each device constituting the system 1 may recognize a unique flight in the system 1 by combining the first identification information and the second identification information. As another method for managing unique flights in the system 1, the control device 100 may issue and manage second identification information to the mobile terminal 600. In this case, the first request message does not include second identification information for identifying the flight of the mobile terminal 600. In this case, the control device 100 distributes the second identification information to devices in the system 1, including the mobile terminal 600.

[0217] -Frequency information For example, the radio resource is a radio resource in a specific frequency band, and the first request message includes frequency information indicating the specific frequency band.

[0218] The frequency band may be a component carrier (CC), or may be a bandwidth part (BWP) included in a CC, or may be a band including multiple CCs.

[0219] Of course, the frequency information may indicate multiple frequency bands, and the frequency information may indicate the multiple frequency bands in order of priority. For example, by giving a higher priority to lower frequencies, it is possible to stabilize wireless connections with flying mobile terminals.

[0220] According to the frequency information as described above, the CN 10 can request the wireless station 500 to reserve wireless resources in a desired frequency band.

[0221] -Time information For example, the radio resource is a radio resource for a specific time period, and the first request message includes time information indicating the specific time period.

[0222] For example, the specific time includes a time when the mobile terminal 600 moving according to the flight path information is scheduled to communicate with the wireless station 500 .

[0223] According to the time information as described above, the CN 10 can request the wireless station 500 to reserve wireless resources for the desired time (i.e., the time when the mobile terminal 600 is scheduled to communicate with the wireless station 500).

[0224] -Location information For example, the first request message includes location information indicating a location, and the wireless station 500 for which the wireless resources are to be reserved corresponds to the location information. That is, the CN 10 identifies or determines the wireless station 500 for which the wireless resources are to be reserved based on the location information.

[0225] For example, the location information is a cell identifier (cell ID). In this case, the radio station 500 that reserves the radio resources is identified based on the cell identifier. Note that the location information may include multiple cell identifiers, and multiple radio stations 500 may be identified.

[0226] Alternatively, the location information is GPS (Global Positioning System) information or information indicating a waypoint (hereinafter referred to as waypoint information) for the flight of the mobile terminal 600. For example, the waypoint information is also GPS information. In this case, the wireless station 500 that secures the wireless resource is determined based on the GPS information or the waypoint information. Note that the location information may include GPS information of a plurality of positions or information of a plurality of waypoints, and a plurality of wireless stations 500 may be identified.

[0227] -Session attribute information For example, the first request message includes session attribute information required for communication between the mobile terminal 600 and the control device 100. The session attribute information may be expressed as QoS (Quality of Service) information. The session attribute information may include QoS Profile information indicating the type of resource and the amount of resource. The QoS Profile information may include a 5G QoS Identifier (5QI), Allocation and Retention Priority (ARP), Reflective QoS Attribute (RQA), Guaranteed Flow Bit Rate (GFBR) - UL and DL, Maximum Flow Bit Rate (MFBR) - UL and DL, and / or Maximum Packet Loss Rate - UL and DL.

[0228] According to the location information as described above, the CN 10 can determine a desired wireless station and can request that the wireless resources of the desired cell be reserved for the desired wireless station.

[0229] (1-2) Requirements for radio stations For example, in response to receiving the first request message in CN10, the first CN node 200 (communication processing unit 233) transmits a second request message requesting the reservation of the radio resources to the radio station 500 that reserves the radio resources.

[0230] More specifically, for example, the control device 100 (communication processing unit 133) transmits the first request message to the second CN node 300, and the second CN node 300 (communication processing unit 333) receives the first request message from the control device 100. In response to receiving the first request message, the second CN node 300 (communication processing unit 333) transmits a third request message to the first CN node 200 requesting the reservation of the radio resources, and the first CN node 200 (communication processing unit 233) receives the third request message from the second CN node 300. In response to receiving the third request message, the first CN node 200 (communication processing unit 233) transmits the second request message to the radio station 500 requesting the reservation of the radio resources, and the radio station 500 (first communication processing unit 543) receives the second request message. In response to receiving the second request message, the wireless station 500 (control unit 541) reserves the wireless resources.

[0231] - Information contained in the third request message For example, the third request message transmitted by the second CN node 300 includes the above-mentioned information included in the first request message transmitted by the control device 100.

[0232] Specifically, for example, the third request message includes the first identification information, the second identification information, the frequency information, the time information, the location information, and / or the session attribute information.

[0233] For example, the first CN node 200 (control unit 231) identifies or determines the radio station 500 that will secure the radio resources (i.e., the radio station 500 to which the first CN node 200 will send the second request message) based on the location information.

[0234] -information contained in the second request message For example, the second request message sent by the second CN node 300 includes the above-mentioned information included in the first request message and the third request message.

[0235] Specifically, for example, the second request message includes the first identification information, the second identification information, the frequency information, the time information, and / or the session attribute information.

[0236] Two or more of the first request message, the second request message, and the third request message may contain the same information, or two or more of the first request message, the second request message, and the third request message may be the same message.

[0237] (2) Responding to requests for resources The control device 100 (communication processing unit 133) receives the first response message regarding the reservation of the wireless resources. For example, the control device 100 receives the first response message regarding the reservation of the wireless resources from the wireless station 500 via OAM. Also, for example, the control device 100 receives the first response message regarding the reservation of the wireless resources from the CN 10. The following describes an example of the operation of the control device 100 when it receives a first response message from the CN 10. An example of the operation of the control device 100 when it receives a first response message from the wireless station 500 via OAM will be described in (5) Second Modification.

[0238] (2-1) Information included in the first response message For example, the first response message includes information indicating whether the radio resources have been secured. More specifically, the information is, for example, information indicating that the radio resources have been secured (for example, information indicating "OK"), or information indicating that the radio resources have not been secured (for example, information indicating "Reject").

[0239] For example, the first response message may include information indicating the reserved radio resources.

[0240] (2-2) Response from the radio station For example, the radio station 500 (first communication processing unit 543) transmits a second response message regarding the reservation of the radio resources to the first CN node 200, and the first CN node 200 (communication processing unit 233) receives the second response message from the radio station 500. In response to receiving the second response message, the first CN node 200 (communication processing unit 233) transmits a third response message regarding the reservation of the radio resources to the second CN node 300, and the second CN node 300 (communication processing unit) receives the third response message from the first CN node 200. In response to receiving the third response message, the second CN node 300 (communication processing unit) transmits the first response message to the control device 100.

[0241] -Information contained in the second response message For example, the second response message sent by the wireless station 500 includes the above-mentioned information included in the first response message.

[0242] Specifically, for example, the second response message may include information indicating whether the radio resources have been secured. The second response message may include information indicating the secured radio resources.

[0243] -Information contained in the third response message For example, the third response message sent by the first CN node 200 includes the above-mentioned information included in the first response message and the second response message.

[0244] Specifically, for example, the third response message may include information indicating whether the radio resources have been secured. The third response message may also include information indicating the secured radio resources.

[0245] Two or more of the first response message, the second response message, and the third response message may contain the same information. Also, two or more of the first response message, the second response message, and the third response message may be the same message.

[0246] (3) Processing flow -Summary 15 is a first sequence diagram illustrating an example of a schematic flow of a process for reserving radio resources according to the second aspect. The first sequence diagram is a schematic sequence diagram.

[0247] In FIG. 15, for clarity, as a specific example, the radio station 500 is described as an NG-RAN node, and the mobile terminal 600 is described as a UE.

[0248] The UE 600 transmits a flight request for the flight of the UE 600 to the control device 100 (S1301). This transmission is performed at the application layer. The control device 100 plans the flight in accordance with the flight request. For example, the control device 100 determines the route of the flight.

[0249] A request message requesting reservation of radio resources for the UE 600 is transmitted from the control device 100 to the NG-RAN node 500A (S1303). For example, the request message includes the first identification information, the second identification information, the frequency information, the time information, and / or the location information. Furthermore, the request message may include flight-related information and flight path information.

[0250] Furthermore, a response message to the request message is transmitted from the NG-RAN node 500A to the control device 100 (S1305). For example, the response message includes information indicating that the radio resources have been secured.

[0251] Similar to the NG-RAN node 500A, the request message and the response message are transmitted and received between the NG-RAN node 500B and the NG-RAN node 500C (S1307 to S1313).

[0252] The control device 100 transmits a response (flight response) to the flight request to the UE 600 (S1315). The transmission of the flight response is a transmission at the application layer. For example, the flight response includes information indicating acceptance of the flight by the UE 600 (for example, information indicating "OK"). Also, for example, the flight response includes the first identification information and the second identification information. Note that the flight response may include flight path information and flight-related information for the mobile terminal 600 generated or acquired by the control device 100. As a result, the mobile terminal 600 may acquire the flight path information.

[0253] In the example of FIG. 15, "NG-RAN node" may be replaced with "wireless station" and "UE" may be replaced with "mobile terminal."

[0254] -detail 16 is a second sequence diagram for explaining an example of a schematic flow of a process for securing radio resources according to the second aspect. The second sequence diagram is a sequence diagram showing an example of a case where the control device 100 receives a first response message regarding the securing of the radio resources from the CN 10, and particularly explains steps S1303 and S1305 in the first sequence diagram shown in FIG. 15 in more detail.

[0255] In FIG. 16, for ease of understanding, as a specific example, the radio station 500 is described as an NG-RAN node, the first CN node 200 is described as an AMF, the second CN node 300 is described as an NEF, the third CN node 400 is described as an SMF, and the mobile terminal 600 is described as a UE.

[0256] The control device 100 transmits the above-mentioned first request message (for example, a Nnef_Radio_reconfiguration_request message or a message defined by another name) requesting the reservation of radio resources for the UE 600 to the CN 10 (specifically, the NEF 300) (S1311).

[0257] In response to receiving the first request message (Nnef_Radio_reconfiguration_request message), NEF300 transmits the above-mentioned third request message (for example, a Namf_Radio_reconfiguration_request message or a message defined by another name) requesting reservation of radio resources for UE600 to AMF200 (S1313). NEF300 determines the AMF200 to which the third request message is to be transmitted based on the first identification information set in the first request message (Nnef_Radio_reconfiguration_request message).

[0258] In response to receiving the third request message (Namf_Radio_reconfiguration_request message), AMF200 transmits the second request message (e.g., a RAN RECONFIGURATION REQUEST message or a message defined by another name) to the NG-RAN node 500 requesting the reservation of radio resources for UE600 (S1315).

[0259] Each of the Nnef_Radio_reconfiguration_request message, the Namf_Radio_reconfiguration_request message and the RAN RECONFIGURATION REQUEST message includes first identification information for identifying UE 600, second identification information for identifying the flight of UE 600, frequency information indicating a specific frequency band, time information indicating a specific time, location information indicating a location, and / or session attribute information.

[0260] In response to receiving the RAN RECONFIGURATION REQUEST message, the NG-RAN node 500 reserves radio resources for the UE 600. Then, the NG-RAN node 500 transmits the above-mentioned second response message (for example, a RAN RECONFIGURATION RESPONSE message or a message defined by another name) regarding the reservation of the radio resources to the AMF 200 (S1317).

[0261] The AMF 200 transmits the third response message (for example, a Namf_Radio_reconfiguration_response message or a message defined by another name) regarding the reservation of the radio resources to the NEF 300 (S1319).

[0262] The NEF 300 transmits the first response message (for example, a Nnef_Radio_reconfiguration_response message or a message defined by another name) regarding the reservation of the radio resources to the control device 100 (S1321).

[0263] Each of the RAN RECONFIGURATION RESPONSE message, the Namf_Radio_reconfiguration_response message, and the Nnef_Radio_reconfiguration_response message includes, for example, information indicating that the radio resources have been reserved. Each of these messages may further include information indicating the reserved radio resources.

[0264] In the example of Figure 16, "NG-RAN node" may be replaced with "radio station," "AMF" may be replaced with "first CN node," "NEF" may be replaced with "second CN node," "SMF" may be replaced with "third CN node," and "UE" may be replaced with "mobile terminal." Also, each of the messages shown in Figure 16 may be replaced with "message."

[0265] The NG-RAN node 500 that has secured the radio resources may take the following measures in response to the operation of a Self-Organizing Network (SON) defined by 3GPP, for example.

[0266] For example, when the NG-RAN node 500 that has reserved radio resources receives a proposal to turn off the cell and / or neighboring RAN node, the NG-RAN node 500 may send a negative response, thereby avoiding an increased load on the NG-RAN node 500 that has reserved radio resources due to the neighboring RAN node being turned off.

[0267] For example, the NG-RAN node 500 that has reserved radio resources may transmit a request to start up the cell of a neighboring RAN node in the SON that is turned off and / or the neighboring NG-RAN node 500. By activating the neighboring RAN node, it is possible to distribute the load of the NG-RAN node 500 that has reserved radio resources and provide stable communication to the flying UE.

[0268] (4) First Modification As described above, for example, the third request message is transmitted from the second CN node 300 to the first CN node 200, and the third response message is transmitted from the first CN node 200 to the second CN node 300. However, the transmission of the third request message and the third response message is not limited to this example.

[0269] The second CN node 300 (communication processing unit 333) may transmit the third request message to the third CN node 400 in response to receiving the first request message transmitted by the control device 100. The third CN node 400 (communication processing unit 433) may transmit a further request message (fourth request message) to the first CN node 200 in response to receiving the third request message, requesting the reservation of radio resources for the UE 600.

[0270] The first CN node 200 (communication processing unit 233) may transmit the third response message to the third CN node 400 in response to receiving the second request message transmitted by the radio station 500. The third CN node 400 (communication processing unit 433) may transmit a further response message (fourth response message) regarding the reservation of the radio resources to the second CN node 300 in response to receiving the third response message.

[0271] (5) Second Modification As described above, for example, the request message and response message for securing radio resources are transmitted by signaling within the CN 10. However, the transmission of the request message and response message is not limited to this example.

[0272] The request message may be transmitted from the control device 100 to the wireless station 500 via OAM. Also, the response message may be transmitted from the wireless station 500 to the control device 100 via OAM. In this case, the control device 100 may be an OAM node.

[0273] 17 is a sequence diagram illustrating an example of a schematic flow of a process for reserving radio resources according to a second modification of the second aspect. This sequence diagram particularly describes in more detail steps S1303 and S1305 of the first sequence diagram shown in FIG.

[0274] In FIG. 17, for clarity, the radio station 500 is depicted as an NG-RAN node as a specific example.

[0275] The control device 100 transmits a request message (e.g., a resource reservation request message) requesting reservation of radio resources for the UE 600 to the NG-RAN node 500 via OAM (S1331). For example, the request message includes the first identification information, the second identification information, the frequency information, the time information, the location information, and / or session attribute information (QoS information).

[0276] The NG-RAN node 500 transmits a response message regarding the reservation of the radio resources (e.g., a resource reservation response message) to the control device 100 via OAM (S1333). For example, the response message includes information indicating that the radio resources have been reserved. The response message may further include information indicating the reserved radio resources.

[0277] In the example of FIG. 17, "NG-RAN node" may be replaced with "wireless station."

[0278] The second aspect has been described above. If reservation of radio resources for the mobile terminal 600 moving according to the flight path information is not requested, the radio resources will not be reserved, and it may be difficult for the mobile terminal 600 to communicate continuously during flight. As a result, it may be difficult to appropriately control the flight of the mobile terminal 600 from the outside. On the other hand, if reservation of radio resources for the mobile terminal 600 is requested in advance according to the flight path information as described above, the radio resources on the flight path of the mobile terminal 600 will be reserved in advance, making it easier for the mobile terminal 600 to communicate continuously during flight. As a result, it may be easier to ensure the flight of the mobile terminal 600 and the safety of the crew aboard the mobile terminal 600.

[0279] <<6. Third Aspect>> Next, a third aspect of the present disclosure will be described with reference to FIG.

[0280] (1) A request to call a mobile terminal The control device 100 (communication processing unit 133) transmits a first request message to the CN10 requesting paging of the mobile terminal 600 for a flight of the mobile terminal 600 for which radio resources have been secured.

[0281] (1-1) Information included in the request message - First identification information (identification information for the mobile terminal 600) For example, the first request message includes first identification information for identifying the mobile terminal 600. For example, the first identification information is a temporary UE ID.

[0282] - Secondary identification (flight identification) For example, the first request message includes second identification information for identifying the flight of the mobile terminal 600. For example, the second identification information is a flight ID or flight number (e.g., normalized for each mobile terminal 600).

[0283] -Flight related information For example, the first request message includes flight-related information regarding the flight of mobile terminal 600.

[0284] --Relationship between flight-related information and flight route information The flight-related information is information stored and used in the CN 10 (eg, the first CN node 200, the second CN node 300 and / or the third CN node 400) and / or the wireless station 500.

[0285] Meanwhile, the above-mentioned flight path information is information that is transmitted by the control device 100 to the mobile terminal 600 and used for flight by the mobile terminal 600. The flight path information may be generated by the control device 100, or may be acquired by the control device 100 from another device.

[0286] As described above, information including all or part of the flight path information may be referred to as a flight plan, a flight profile, etc. Similarly, information including all or part of the flight-related information may also be referred to as a flight plan, a flight profile, etc. Alternatively, the flight path information itself or the flight-related information itself may be referred to as a flight plan, a flight profile, etc.

[0287] The flight-related information may be the same as the flight path information described above. Alternatively, the flight-related information may be different from the flight path information described above. For example, the flight-related information may include or be included in the flight path information described above. Alternatively, the flight-related information may only partially overlap with the flight path information described above, or may be completely different from the flight path information described above.

[0288] --Flight-related information stored and used at each node The flight-related information stored in each CN node (each of the first CN node 200, the second CN node 300, and the third CN node 400) may be the same as or different from the flight-related information stored in the other CN nodes. Each CN node may store flight-related information including information necessary for that node. The flight-related information may be in a form in which at least one of first identification information and second identification information is identified in each CN node.

[0289] The flight-related information stored and used in the wireless station 500 may be different from the flight-related information stored in the CN 10. The wireless station 500 may store flight-related information including information necessary for the wireless station 500. As an example, the wireless station 500 may include information about its own cell, and the flight-related information stored in the CN 10 may include information about the cells of multiple wireless stations 500. The flight-related information may be such that at least one of the first identification information and the second identification information is identified in the wireless station 500.

[0290] It should be noted that the flight-related information stored and used in the wireless station 500 may be the same as the flight-related information stored in the CN 10 .

[0291] --Identification information The first identification information and the second identification information may be included in the flight-related information, or may be included in the first request message as information separate from the flight-related information.

[0292] --Route information For example, the flight-related information includes route information indicating the route of the flight of the mobile terminal 600 .

[0293] As a first example, the route information indicates, as the route of the flight, one or more cells on the route of the flight, the one or more cells used by the mobile terminal 600 in the flight. That is, the one or more cells are a list of cells used by the mobile terminal 600 in the flight (i.e., a handover list). In the example case of Fig. 3, the one or more cells are a list of four cells 50. The list may be a sequence of the cells (i.e., a list of cells with an order).

[0294] As a second example, the route information may indicate one or more waypoints of the flight as a route for the flight, and the route information may indicate each of the one or more waypoints by latitude, longitude, and altitude.

[0295] The flight-related information may include both first route information indicating the one or more cells and second route information indicating the one or more waypoints.

[0296] --Time information For example, the flight-related information includes time information indicating a time for the flight.

[0297] As a first example, the time information indicates a time for the flight for each of the one or more cells (i.e., one or more cells on the route of the flight that are used by mobile terminal 600 in the flight). More specifically, for example, the time information indicates a time period for which radio resources are reserved for the mobile terminal for each of the one or more cells.

[0298] For example, in the example case of Figure 3, radio resources are reserved for the mobile terminal 600 for four cells at the following times, and the above flight-related information includes time information indicating the following times for the four cells: -First cell 50:15:00-15:05 -Second Cell 50:15:02-15:10 - Third Cell 50:15:08-15:15 -Fourth Cell 50:15:12-15:20 These pieces of time information have a relationship in which, except for time information that includes the time of either the starting point or the ending point of the flight of the mobile terminal 600, there is time information that indicates the time before and after which at least a portion of the time indicated by a certain piece of time information overlaps.

[0299] Additionally or alternatively, the time information may indicate, for each of the one or more cells, a time at which the mobile terminal 600 enters and a time at which the mobile terminal 600 leaves. Additionally or alternatively, the time information may indicate, for each of the one or more cells, a time period during which the mobile terminal 600 passes through (or stays in).

[0300] As a second example, the time information indicates a time for the flight for one or more waypoints of the flight. More specifically, for example, the time information may indicate the time at which the mobile terminal 600 passes through each of one or more waypoints of the flight. The one or more waypoints may be a portion of all waypoints of the flight. Alternatively, the one or more waypoints may be all waypoints of the flight. Additionally or alternatively, the time information may indicate flight time of the mobile terminal 600 for one or more segments, each of which may be a segment between any two waypoints.

[0301] --Movement speed information The flight-related information may include movement speed information indicating the movement speed (velocity) of the mobile terminal 600. For example, the movement speed information may indicate the horizontal movement speed (Horizontal velocity) of the mobile terminal 600 and the vertical movement speed (Vertical velocity) of the mobile terminal 600.

[0302] For example, the movement speed information may indicate the movement speed of the mobile terminal 600 for each of one or more waypoints. Alternatively, the movement speed information may indicate the movement speed of the mobile terminal 600 for one or more sections, and the one or more sections may be sections between any two waypoints.

[0303] --Frequency information The flight-related information may include frequency information indicating a particular frequency band, which may be a frequency band used by the mobile terminal 600 during the flight.

[0304] The frequency information may indicate multiple frequency bands. The frequency information may indicate the multiple frequency bands in order of priority. For example, by giving a higher priority to lower frequencies, it is possible to stabilize wireless connections with flying mobile terminals.

[0305] --Configuration information For example, the flight-related information includes configuration information indicating a configuration for mobile terminal 600 .

[0306] For example, the configuration information indicates a configuration for the mobile terminal 600 for each of the one or more cells (i.e., one or more cells along the route of the flight and used by the mobile terminal 600 in the flight). For example, the configuration information is information included in an RRC (Radio Resource Control) Reconfiguration message.

[0307] --Session attribute information For example, the flight-related information includes attribute information of a session for communication during the flight of the mobile terminal 600. For example, the session attribute information includes information indicating the quality of the session. As an example, the session is a PDU (Packet Data Unit) session, and the session attribute information includes a QCI (Quality of Service (QoS) Class Identifier) or a 5QI (5G QoS Identifier) for the PDU session.

[0308] --Radio resource information For example, the flight-related information includes radio resource information indicating radio resources for communication of the mobile terminal 600 during the flight.

[0309] (1-2) Call For example, the first CN node 200 (communication processing unit 233) performs the above-mentioned page of the mobile terminal 600 via the wireless station 500 in response to receiving the above-mentioned first request message in the CN 10.

[0310] More specifically, for example, the control device 100 (communication processing unit 133) transmits the first request message requesting the call to the second CN node 300, and the second CN node 300 (communication processing unit 333) receives the first request message from the control device 100. In response to receiving the first request message, the second CN node 300 (communication processing unit 333) transmits a second request message requesting the call to the third CN node 400. In response to receiving the second request message, the third CN node 400 (communication processing unit 433) transmits a further request message (third request message) to the first CN node 200, and the first CN node 200 (communication processing unit 233) receives the third request message from the third CN node 400. The first CN node 200 (communication processing unit 233) performs the above-mentioned page of the mobile terminal 600 via the wireless station 500 in response to receiving the above-mentioned third request message.

[0311] For example, each of the second request message and the third request message includes the first identification information, the second identification information, and / or the flight-related information.

[0312] Two or more of the first request message, the second request message, and the third request message may contain the same information, or two or more of the first request message, the second request message, and the third request message may be the same message.

[0313] Note that (1) A request to call a mobile terminal has been described as a process of paging the mobile terminal 600 from the control device 100 (communication processing unit 133), but if the mobile terminal 600 is in a CM-CONNECTED state rather than a CM-IDLE state, the AMF 200 transmits a NOTIFICATION message to the mobile terminal 600 to prompt the mobile terminal 600 to transmit a Service request message. In this case, (1) A request to call a mobile terminal does not need to be executed.

[0314] (2) Request to start communication The mobile terminal 600 (communication processing unit 635) transmits a message requesting the start of communication for the flight of the mobile terminal 600 for which radio resources have been secured to the first CN node 200. For example, the message is a Service request message.

[0315] -Send in response to calls For example, in response to the page of the mobile terminal 600, the mobile terminal 600 (communication processing unit 635) transmits the message requesting the start of the communication to the first CN node 200.

[0316] -Send without a call trigger "(1) Request for paging of mobile terminal" describes the process of paging the mobile terminal 600 from the control device 100 (communication processing unit 133), but for example, the mobile terminal 600 may set up a PDU session without undergoing the above-mentioned paging process. In this case, the setting up of the PDU session is initiated by the mobile terminal 600 transmitting the above-mentioned message (e.g., a Service request message) requesting the start of the communication to the first CN node 200 in accordance with at least one of the flight-related information and the flight path information. For example, the mobile terminal 600 may transmit the above-mentioned message (e.g., a Service request message) requesting the start of the communication to the first CN node 200 using at least one of the flight path information and the flight-related information included in the flight response received at S1315 in the second aspect.

[0317] -Session settings For example, in response to receiving the above message, the first CN node 200 (control unit 231 and communication processing unit 233) establishes a session for the mobile terminal 600 together with the third CN node 400. For example, the session is a PDU (Packet Data Unit) session.

[0318] -Transmit flight-related information For example, after receiving the message requesting the start of the communication (e.g., a Service request message), the first CN node 200 (communication processing unit 233) transmits the flight-related information to the radio station 500, and the radio station 500 (first communication processing unit 543) receives the flight-related information.

[0319] Furthermore, the wireless station 500 (second communication processing unit 545) may transmit the flight-related information to the mobile terminal 600.

[0320] -Send flight route information The above-mentioned flight path information (i.e., information generated or acquired by the control device 100 and used by the mobile terminal 600 for flight) may be transmitted to the mobile terminal 600 after transmitting the message requesting the start of the communication (e.g., a Service request message). For example, when the message requesting the start of the communication is received at the first CN node 200, the CN10 may notify the control device 100. In response to the notification from the CN10, the control device 100 may transmit the above-mentioned flight path information to the mobile terminal 600.

[0321] 15 in the second embodiment, the flight path information may be transmitted in advance in a flight response to a flight request from the mobile terminal 600. In this case, the mobile terminal 600 (communication processing unit 635) may include the flight path information in the message requesting the start of the communication (e.g., a Service request message). This allows the mobile terminal 600 to provide the flight path information to the CN10 (first CN node 200).

[0322] (3) Processing flow FIG. 18 is a sequence diagram illustrating an example of a schematic flow of a process according to the third aspect.

[0323] In FIG. 18, for clarity, as a specific example, the radio station 500 is described as an NG-RAN node, the first CN node 200 is described as an AMF, the second CN node 300 is described as an NEF, the third CN node 400 is described as an SMF, and the mobile terminal 600 is described as a UE.

[0324] The control device 100 sends the above-mentioned first request message (e.g., an Nnef_NIDD_Delivery Request message or a message defined by another name) to CN10 (specifically, NEF300) requesting a call for UE600 for a flight of UE600 for which radio resources have been reserved (S1401).

[0325] In response to receiving the Nnef_NIDD_Delivery Request message, the NEF 300 transmits the second request message (for example, an Nnef_NIDD_Delivery Request message or a message defined by another name) to the SMF 400 (S1403).

[0326] In response to receiving the above-mentioned Nnef_NIDD_Delivery Request message, SMF400 sends the above-mentioned third request message (e.g., a Namf_Communication_N1N2MessageTransfer message or a message defined by another name) to AMF200 requesting a call to UE600 (S1405).

[0327] Each of the Nnef_NIDD_Delivery Request message and the Namf_Communication_N1N2MessageTransfer message includes first identification information for identifying the UE 600, second identification information for identifying the flight of the UE 600, and / or flight-related information regarding the flight of the mobile terminal 600.

[0328] In response to receiving the third request message (for example, a Namf_Communication_N1N2MessageTransfer message or a message defined by another name), the AMF 200 calls the UE 600 via the NG-RAN node 500 (S1407, S1409).

[0329] The AMF 200 transmits an N11 message to the SMF 400 (S1411), the SMF 400 transmits an Nnef_NIDD_Delivery Response message to the NEF 300 (S1413), and the NEF 300 transmits an Nnef_NIDD_Delivery Response message to the control device 100 (S1415).

[0330] The UE 600 transmits a Service request message to the AMF 200 (S1421).

[0331] AMF200 and SMF400 set up a PDU session for UE600 (S1423).

[0332] The AMF 200 sends a PDU SESSION RESOURCE SETUP REQUEST message to the NG-RAN node 500 (S1425). The PDU SESSION RESOURCE SETUP REQUEST message includes the first identification information, the second identification information, and / or the flight-related information.

[0333] The NG-RAN node 500 sends an RRC Reconfiguration message to the UE 600 (S1427). The RRC Reconfiguration message may include the first identification information, the second identification information, and / or the flight-related information.

[0334] The NG-RAN node 500 transmits a PDU SESSION RESOURCE SETUP Response message to the AMF 200 (S1429).

[0335] The AMF 200 and SMF 400 update the PDU session (S1431).

[0336] In the example of Figure 18, "NG-RAN node" may be replaced with "radio station," "AMF" may be replaced with "first CN node," "NEF" may be replaced with "second CN node," "SMF" may be replaced with "third CN node," and "UE" may be replaced with "mobile terminal." Also, each of the messages shown in Figure 18 may be replaced with "message." Also, in the example of Figure 18, if UE 600 sets up a PDU session without undergoing paging processing, there is no need to perform the processes of S1401, S1403, S1405, S1407, S1409, S1411, S1413 and S1415 described in Figure 18, and UE 600 simply sends a Service request message to the first CN node 200 (S1421).

[0337] (4) Variations As described above, for example, the second CN node 300 transmits the second request message to the third CN node 400, and the third CN node 400 transmits the third request message to the first CN node 200. However, the transmission of the request message is not limited to this example.

[0338] In response to receiving the first request message from the control device 100, the second CN node 300 (communication processing unit 333) may transmit the second request message to the first CN node 200. The first CN node 200 (communication processing unit 233) may receive the second request message from the second CN node 300. In response to receiving the second request message, the first CN node 200 (communication processing unit 233) may perform the above-mentioned call to the mobile terminal 600 via the radio station 500.

[0339] The second request message may be a Namf_Communication_N1N2MessageTransfer message.

[0340] The third aspect has been described above.

[0341] In this aspect, at least one of the mobile terminal 600 and the control device 100 requests the start of communication based on at least one of the flight path information and the flight-related information. Since at least one of the flight path information and the flight-related information is information that ensures that radio resources are secured along the flight path of the mobile terminal 600, requesting the start of communication based on this information may make it easier for the mobile terminal 600 to communicate continuously during flight. As a result, it may be easier to ensure the flight of the mobile terminal 600 and the safety of the crew aboard the mobile terminal 600.

[0342] Furthermore, for example, if a call to the mobile terminal 600 is not requested, the flight of the mobile terminal 600 is started autonomously by the mobile terminal 600. Therefore, it may be difficult for the control device 100 to control the flight of the mobile terminal 600 from the start. On the other hand, as explained in (1) of the third aspect, if a call to the mobile terminal 600 is requested, the flight of the mobile terminal 600 is started in response to a request from the network. Therefore, it becomes possible for the control device 100 to control the flight of the mobile terminal 600 from the start.

[0343] <<7. Fourth Aspect>> Next, a fourth aspect of the present disclosure will be described with reference to FIGS.

[0344] The fourth aspect is a handover of a mobile terminal 600 that moves according to flight path information. The handover is between two wireless stations 500, and hereinafter, the target wireless station of the two wireless stations 500 will be referred to as the "first wireless station 500A," and the source wireless station of the two wireless stations 500 will be referred to as the "second wireless station 500B."

[0345] (1) Handover Procedures The first wireless station 500A (control unit 541) controls handover of the mobile terminal 600 that moves in accordance with the flight path information from the second wireless station 500B (source wireless station) to the first wireless station 500A (target wireless station) in accordance with the flight path information. The second wireless station 500B (control unit 541) also controls the handover.

[0346] (1-1) Handover -Source cell and target cell As described above, the handover is a handover from the second radio station 500B to the first radio station 500A. More specifically, for example, the handover is a handover from the cell of the second radio station 500B (i.e., the source cell) to the cell of the first radio station 500A (i.e., the target cell). Furthermore, the second radio station 500B and the first radio station 500A may be the same radio station. That is, the handover may be a handover between cells within the same radio station 500.

[0347] -Handover according to flight path information As described above, the handover is a handover in accordance with the flight path information. More specifically, for example, the flight path information includes route information (e.g., information indicating waypoints) indicating a flight path of the mobile terminal 600, and the handover is a handover planned on the premise that the mobile terminal 600 will move along the flight path.

[0348] The flight path information may include information indicating a list of cells used in the flight of the mobile terminal 600, and the handover may be a handover between two cells included in the list. Alternatively, the handover may be a handover between cells (between cells using the same frequency or between cells using different frequencies) indicated in the route information indicating the flight path of the mobile terminal 600, for example, where information indicating waypoints indicates the same waypoint and indicates cells associated with information indicated by each waypoint.

[0349] (1-2) Securing radio resources at the first radio station For example, the first radio station 500A (control unit 541) reserves radio resources for the mobile terminal 600 in the first radio station 500A.

[0350] More specifically, for example, the first radio station 500A (control unit 541) reserves the radio resources based on flight-related information related to the flight of the mobile terminal 600.

[0351] (a) Flight-related information For example, the flight-related information includes information similar to the flight-related information described in the third embodiment.

[0352] For example, the flight-related information includes first identification information for identifying the mobile terminal 600. For example, the flight-related information includes second identification information for identifying the flight of the mobile terminal 600.

[0353] For example, the flight-related information includes route information indicating the route of the flight of the mobile terminal 600, time information indicating the time for the flight of the mobile terminal 600, movement speed information indicating the movement speed of the mobile terminal 600, frequency information indicating a specific frequency band, configuration information indicating a configuration for the mobile terminal 600, attribute information of a session for communication during the flight of the mobile terminal 600, and / or radio resource information indicating radio resources for communication during the flight of the mobile terminal 600. Detailed descriptions of the various types of information are the same as those of the various types of information in the third aspect, for example. Therefore, redundant descriptions will be omitted here. However, the various types of information are not limited to the examples described in the third aspect.

[0354] For example, the flight-related information includes, inter alia, the route information, the time information, the configuration information, the session attribute information and / or the radio resource information for one or more cells (including a target cell) of the first radio station 500A on the route of the flight and used by the mobile terminal 600 in the flight.

[0355] The relationship between the flight-related information and the flight path information is the same as that described in the third embodiment, for example. Therefore, a duplicated description will be omitted here. However, the relationship is not limited to the example described in the third embodiment.

[0356] It should be noted that although the description of the third aspect is referred to, this reference is merely for the sake of omission of description, and the fourth aspect does not depend on the third aspect. The fourth aspect may be independent of the third aspect. Alternatively, the fourth aspect may be combined with the third aspect. When the fourth aspect and the third aspect are combined, the flight-related information in the fourth aspect may be the same as the flight-related information in the third aspect.

[0357] (b) Methods for securing resources For example, the first radio station 500A (control unit 541) may determine whether the radio resources can be secured based on the flight-related information, and secure the radio resources based on the result of the determination. Note that the first radio station 500A (control unit 541) may secure the resources without determining whether the radio resources can be secured. An example of this will be described later.

[0358] As an example, the first radio station 500A (control unit 541) determines whether radio resources can be secured in each of one or more cells of the first radio station 500A indicated by the above-mentioned route information at the time indicated by the above-mentioned time information so that the quality indicated by the above-mentioned session attribute information is satisfied.

[0359] For example, the first radio station 500A (control unit 541) determines that the radio resources can be secured. In this case, the first radio station 500A (control unit 541) secures the radio resources.

[0360] For example, the first radio station 500A (control unit 541) determines that the radio resources cannot be secured. The process in this case will be described in detail later.

[0361] (c) Radio Resources For example, the radio resource (reserved by the first radio station 500A) is at least one of time and frequency resources. That is, the radio resource is a radio resource in the narrow sense. As an example, the radio resource is a time-frequency resource.

[0362] Alternatively, the radio resources may include at least one of time and frequency resources (radio resources in a narrow sense) and resources for processing by the first radio station 500A. That is, the radio resources may be radio resources in a broad sense. The resources for processing by the first radio station 500A may include transport network layer (TNL) resources of the first radio station 500A and / or a processing load of the first radio station 500A.

[0363] (1-3) Sending and receiving messages The first wireless station 500A (first communication processing unit 543) triggers (or starts, hereinafter the same) processing to transmit a message including information regarding the acceptance of the handover (hereinafter referred to as acceptance information) to the second wireless station 500B.

[0364] The message may be an X2AP or XnAP message sent directly from the first wireless station 500A to the second wireless station 500B, a message sent from the CN10 to the second wireless station 500B, or a message sent from the first wireless station 500A to the second wireless station 500B via the CN10.

[0365] If the message is an X2AP or XnAP message, the first wireless station 500A may directly trigger a process of transmitting the message to the second wireless station 500B. If the message is a message transmitted from the CN10 to the second wireless station 500B, the first wireless station 500A may trigger a process of requesting the CN10 to transmit the message and / or another message including the message to the second wireless station 500B. If the message is a message transmitted from the first wireless station 500A to the second wireless station 500B via the CN10, the first wireless station 500A may trigger a process of transmitting the message to the CN10.

[0366] The second wireless station 500B (first communication processing unit 543) receives the message including the acceptance information.

[0367] For example, the message including the acceptance information is a message that notifies the second radio station 500B that the first radio station 500A is ready for the handover. As an example, the message including the acceptance information is a Handover Ready Notification message. Of course, the message including the acceptance information may be a message with another name (for example, a Handover Preparation Notification message, a Handover Allowance Indication message, etc.).

[0368] (a) Examples of transmission methods -Direct transmission The message containing the acceptance information may be sent directly from the first wireless station 500A to the second wireless station 500B.

[0369] The first wireless station 500A (first communication processing unit 543) may directly transmit the message including the acceptance information to the second wireless station 500B.

[0370] The second wireless station 500B (first communication processing unit 543) may receive the message including the acceptance information from the first wireless station 500A.

[0371] 19 is a sequence diagram for explaining an example of direct transmission of the message (e.g., Handover Ready Notification message or a message defined by another name) including the acceptance information according to the fourth aspect. A first radio station 500A (target RAN node) transmits the message (e.g., Handover Ready Notification message or a message defined by another name) including the acceptance information to a second radio station 500B (source RAN node) (S1501).

[0372] -Indirect transmission The message including the acceptance information may be transmitted from the first wireless station 500A to the second wireless station 500B via the first CN node 200. That is, the message including the acceptance information may be transmitted from the first wireless station 500A to the first CN node 200, and from the first CN node 200 to the second wireless station 500B.

[0373] The first radio station 500A (first communication processing unit 543) may transmit the message including the acceptance information to the second radio station 500B via the first CN node 200. That is, the first radio station 500A (first communication processing unit 543) may transmit the message including the acceptance information to the first CN node 200, and the first CN node 200 may transmit the message including the acceptance information to the second radio station 500B. The first CN node 200 may transmit the message including the acceptance information itself to the second radio station 500B. Alternatively, the first CN node 200 may transmit another message including the message including the acceptance information to the second radio station 500B. As an example, the message including the acceptance information may be encapsulated within the other message. In this case, the message including the acceptance information may be included in a transparent container within the other message.

[0374] The second radio station 500B (first communication processing unit 543) may receive the message including the acceptance information from the first CN node 200 that receives the message including the acceptance information from the first radio station 500A.

[0375] 20 is a sequence diagram for explaining an example of indirect transmission of the message (e.g., Handover Ready Notification message or a message defined by another name) including the acceptance information according to the fourth aspect. The first radio station 500A (target RAN node) transmits the message (Handover Ready Notification message or a message defined by another name) including the acceptance information to the CN10 (first CN node 200) (S1503). The CN10 (first CN node 200) transmits the message (Handover Ready Notification message or a message defined by another name) including the acceptance information to the second radio station 500B (source RAN node) (S1505). Note that the CN10 (first CN node 200) may transmit the Handover Ready Notification message itself to the second radio station 500B (source RAN node). Alternatively, the CN 10 (first CN node 200) may send another message including the above Handover Ready Notification message to the second radio station 500B (source RAN node).

[0376] -others The first radio station 500A may send another message to the first CN node 200 to trigger transmission of the message including the acceptance information. This other message may include at least one of the acceptance information and the message including the acceptance information. Upon receiving the other message that triggers transmission of the message including the acceptance information, the CN node 200 may send the message including the acceptance information to the second radio station 500B.

[0377] The first radio station 500A (first communication processing unit 543) may cause the first CN node 200 to transmit the message including the above-mentioned acceptance information to the second radio station 500B by transmitting to the first CN node 200 another message that triggers transmission of the above-mentioned message including the above-mentioned acceptance information from the first CN node 200 to the second radio station 500B. In other words, the first CN node 200 may perform processing to transmit the above-mentioned message in response to receiving the other message.

[0378] The second wireless station 500B (first communication processing unit 543) may receive the message including the acceptance information from the first CN node 200 that receives the other message from the first wireless station 500A.

[0379] As an example, the message including the acceptance information may be a Handover Ready Notification message, and the other message may be a Handover Ready Indication message.

[0380] 21 is a sequence diagram illustrating another example of transmission of a message including the above-mentioned acceptance information (e.g., a Handover Ready Notification message or a message defined by another name) according to the fourth aspect. The first radio station 500A (target RAN node) transmits a message including the above-mentioned acceptance information (e.g., a Handover Ready Indication message or a message defined by another name) to the CN10 (first CN node 200) (S1507). The CN10 (first CN node 200) transmits a message including the above-mentioned acceptance information (e.g., a Handover Ready Notification message or a message defined by another name) to the second radio station 500B (source RAN node) (S1509).

[0381] (b) Sending without receiving a request message The first radio station 500A (first communication processing unit 543) triggers processing to transmit the message including the acceptance information to the second radio station 500B without receiving the request message for handover transmitted from the second radio station 500B.

[0382] The second wireless station 500B (first communication processing unit 543) receives the message including the acceptance information without transmitting the request message for handover.

[0383] For example, the second radio station 500B (first communication processing unit 543) may transmit the request message for handover when it receives the message including the acceptance information, without transmitting (i.e., even if it has not transmitted) a request message for handover before receiving the message including the acceptance information.

[0384] For example, the first radio station 500A (first communication processing unit 543) may receive the request message for handover transmitted from the second radio station 500B when the first radio station 500A transmits the message including the acceptance information to the second radio station 500B without receiving (i.e., even if it has not received) the request message for handover transmitted from the second radio station 500B before transmitting the message including the acceptance information to the second radio station 500B.

[0385] For example, the request message for handover is a Handover Request message, and the response message to the request message for handover is a Handover Request Acknowledge message.

[0386] (c) Acceptance Information - Information about securing radio resources For example, the acceptance information includes information indicating that radio resources for the mobile terminal 600 have been reserved.

[0387] Specifically, for example, when the first radio station 500A (control unit 541) determines that the radio resources can be secured and secures the radio resources, the acceptance information includes the information indicating that the radio resources have been secured.

[0388] Alternatively, the acceptance information may include information indicating that radio resources for the mobile terminal 600 at the first radio station 500A cannot be secured.

[0389] Specifically, when the first radio station 500A (control unit 541) determines that the radio resources cannot be secured, the acceptance information may include information indicating that the radio resources cannot be secured.

[0390] - Information about the target cell The admission information may include information about the target cell of the handover (ie, the cell of the first radio station 500A).

[0391] Specifically, for example, the information about the target cell may include identification information (cell ID) for identifying the target cell. For example, the information about the target cell may include information about the frequency band of the target cell. The information may be any one or a combination of information about the carrier frequency, frequency band, or synchronization signal of the target cell. The information about the synchronization signal may be information indicating the frequency position of an SS / PBCH Block (SSB).

[0392] (1-4) Processing flow FIG. 22 is a sequence diagram illustrating an example of a schematic flow of handover processing according to the fourth aspect.

[0393] This process is a process of handing over the mobile terminal 600 from the second wireless station 500B (source wireless station) to the first wireless station 500A (target wireless station). For example, this process starts after it is confirmed or determined that the wireless resources for the mobile terminal 600 in the first wireless station 500A are secured, or after it is confirmed or determined that the first wireless station 500A can accept the handover of the mobile terminal 600.

[0394] 19, the first wireless station 500A transmits a Handover Ready Notification message to the second wireless station 500B (S1501). The Handover Ready Notification message includes information related to the acceptance of the handover (acceptance information).

[0395] In response to receiving the Handover Ready Notification message, the second wireless station 500B transmits a Handover Request message to the first wireless station 500A (S1511).

[0396] In response to receiving the Handover Request message, the first wireless station 500A transmits a Handover Request Acknowledge message to the second wireless station 500B (S1513).

[0397] In response to receiving the Handover Request Acknowledge message, the second radio station 500B transmits an RRC Reconfiguration message to the mobile terminal 600 (S1515).

[0398] The mobile terminal 600 performs random access to the target cell (the cell of the first radio station 500A) (S1517). Furthermore, the mobile terminal 600 transmits an RRC Reconfiguration Complete message to the first radio station 500A (S1519).

[0399] The first wireless station 500A and the CN 10 perform a path switch (S1521). The first wireless station 500A transmits a UE Context Release message to the second wireless station 500B (S1523).

[0400] (1-5) First Modified Example As described above, for example, the first wireless station 500A (control unit 541) determines whether the wireless resources can be secured based on the flight-related information, and secures the wireless resources based on the result of the determination. However, the fourth aspect is not limited to this example.

[0401] The first radio station 500A (control unit 541) may always reserve the radio resources without determining whether the radio resources can be reserved.

[0402] At the time of flight planning (for example, by the method described in the second aspect or by other methods), it may be ensured in advance that radio resources for the mobile terminal 600 are reserved at the time (or time period) that the mobile terminal 600 will use or pass through. For example, in such a case, the radio resources may be always reserved.

[0403] In this case, the acceptance information does not include information indicating that radio resources for the mobile terminal 600 have been secured, nor information indicating that radio resources for the mobile terminal 600 at the first radio station 500A cannot be secured, but may include information regarding the target cell of the handover (i.e., the cell of the first radio station 500A).

[0404] (1-6) Second Modification As described above, for example, the second radio station 500B (first communication processing unit 543) may transmit the request message for handover after receiving the message including the acceptance information, without transmitting the request message for handover before receiving the message including the acceptance information. For example, the first radio station 500A (first communication processing unit 543) may receive the request message for handover transmitted from the second radio station 500B when it has transmitted the message including the acceptance information to the second radio station 500B, without receiving the request message for handover transmitted from the second radio station 500B before transmitting the message including the acceptance information to the second radio station 500B. However, the fourth aspect is not limited to this example.

[0405] The second radio station 500B (first communication processing unit 543) may not need to transmit the request message for the handover not only before receiving the message including the acceptance information, but also after receiving the message including the acceptance information.

[0406] Furthermore, the first radio station 500A (first communication processing unit 543) does not need to receive the request message for the handover transmitted from the second radio station 500B not only before transmitting the message including the acceptance information to the second radio station 500B to the second radio station 500B, but also after transmitting the message including the acceptance information to the second radio station 500B.

[0407] In such a case, the message including the acceptance information may trigger the second radio station 500B and the mobile terminal 600 to perform the handover, instead of a response message to the request message for the handover (e.g., a Handover Request Acknowledge message). For example, the message including the acceptance information may trigger the second radio station 500B to transmit a message for performing the handover to the mobile terminal 600. That is, the second radio station 500B (second communication processing unit 545) may transmit a message for performing the handover to the mobile terminal 600 in response to receiving the message including the acceptance information. The message for performing the handover may be an RRC Reconfiguration message or another message.

[0408] As described above, the acceptance information may include information about the target cell of the handover (i.e., the cell of the first radio station 500A). In particular, in the second variant, the information about the target cell may include information indicating a configuration for the mobile terminal 600 in the target cell. The information indicating the configuration may be information to be included in the message for executing the handover (e.g., an RRC Reconfiguration message).

[0409] 22 again, in the second modification, the transmission of the Handover Request (S1511) and the transmission of the Handover Request Acknowledge (S1513) may not be performed. That is, the second radio station 500B may transmit an RRC Reconfiguration message to the mobile terminal 600 (S1515) in response to receiving the Handover Ready Notification message (S1501).

[0410] According to the second modification, for example, signaling in the handover procedure can be reduced, and the handover procedure can be performed more quickly.

[0411] (1-7) Third Modification The procedure for handover according to the fourth aspect is initiated by the first radio station 500A (for example, as described with reference to FIG. 22). However, the fourth aspect is not limited to this example.

[0412] The procedure for handover according to the fourth aspect may be initiated by the first CN node 200.

[0413] Operation of the first CN node 200 The first CN node 200 (control unit 231) may generate a request message for the handover. The first CN node 200 (communication processing unit 233) may transmit the request message to the first radio station 500A without receiving the request message from the second radio station 500B. In other words, the request message is not transmitted from the second radio station 500B to the first CN node 200, but is generated by the first CN node 200 and transmitted to the first radio station 500A.

[0414] The first CN node 200 may store the flight-related information (for example, by the method described in the third aspect or by other methods), and the first CN node 200 (control unit 231) may decide to initiate the handover based on the flight-related information. As an example, the first CN node 200 (control unit 231) may decide to initiate the handover based on the time information included in the flight-related information.

[0415] Operation of the first wireless station 500A The request message may trigger the second radio station 500B to transmit a message including information regarding acceptance of the handover (acceptance information) even if the first radio station 500A has not received the request message for handover transmitted from the second radio station 500B.

[0416] The first radio station 500A (first communication processing unit 543) may receive the request message transmitted from the first CN node 200, and in response to receiving the request message transmitted from the first CN node 200, may transmit the message including the acceptance information to the second radio station 500B.

[0417] -message The request message sent by the first CN node 200 may be a Handover Request message, and the message including the acceptance information sent by the first wireless station 500A may be a Handover Ready Notification message. The request message sent by the first CN node 200 may include flight-related information and flight route information.

[0418] -Processing flow FIG. 23 is a sequence diagram illustrating an example of a schematic flow of handover processing according to the third modified example of the fourth aspect.

[0419] This processing is processing for handing over the mobile terminal 600 from the second wireless station 500B (source wireless station) to the first wireless station 500A (target wireless station).

[0420] The first CN node 200 decides to start the handover, generates a Handover Request message, and transmits the Handover Request message to the first wireless station 500A (S1531).

[0421] In response to receiving the Handover Request message, the first wireless station 500A transmits a Handover Request Acknowledge message to the first CN node 200 (S1533).

[0422] As described with reference to Fig. 19, the first radio station 500A transmits a Handover Ready Notification message to the second radio station 500B (S1501). The Handover Ready Notification message includes information about acceptance of the handover (acceptance information). The acceptance information includes information indicating a configuration for the mobile terminal 600 in a target cell of the handover.

[0423] In response to receiving the Handover Ready Notification message, the second radio station 500B transmits an RRC Reconfiguration message to the mobile terminal 600 (S1535). The RRC Reconfiguration message includes the information indicating the configuration.

[0424] Alternatively, the second radio station 500B may transmit a Handover Ready Notification message, instead of an RRC Reconfiguration message, to the mobile terminal 600. The Handover Ready Notification message may include the information indicating the configuration.

[0425] The mobile terminal 600, the first wireless station 500A, and the second wireless station 500B execute the handover (S1537).

[0426] The first wireless station 500A transmits a Handover Notify message to the first CN node 200 (S1539). The first CN node 200 may adjust the timing of transmitting the next Handover Request message based on the reception of the Handover Notify message.

[0427] The mobile terminal 600 communicates with a first wireless station 500A.

[0428] The first CN node 200 transmits a UE context release command message to the second radio station 500B (S1541), and the second radio station 500B transmits a UE context release command complete message to the first CN node 200 (S1543).

[0429] -Securing radio resources Radio resources for the mobile terminal 600 may be reserved in advance during flight planning (for example, by the method described in the second aspect or by other methods). In such a case, for example, the request message for the handover (for example, a Handover Request message) transmitted by the first CN node 200 may be accepted without being rejected.

[0430] According to the third modification, for example, all handovers during the flight of the mobile terminal 600 can be collectively controlled in the CN 10.

[0431] (1-8) Fourth Modification The handover may not be a normal handover but may be a conditional handover (CHO).

[0432] In the conditional handover (CHO), a source radio station (second radio station 500B) transmits a handover request message (CHO request) of the mobile terminal 600 to a target radio station (first radio station 500A) earlier than in a conventional handover. For example, the source radio station may set a smaller offset value or threshold (e.g., RSRP Threshold, RSRQ Threshold) related to the radio quality of the target cell (and the radio quality of the source cell) in the configuration of an event (e.g., Event Ax, Bx specified in LTE or NR) for the measurement report so that a trigger to execute a measurement report from the terminal occurs earlier than in a conventional handover. Then, upon receiving the measurement report, the source radio station may transmit a handover request message (CHO request). The target radio station transmits a response message (CHO request acknowledgement) to the handover request, which includes a target cell configuration (CHO Configuration) for the CHO of the mobile terminal 600, to the source radio station. The source radio station transmits the target cell configuration together with a CHO execution condition to the mobile terminal 600. Then, the mobile terminal 600 determines whether the CHO execution condition is satisfied, and if satisfied, initiates (executes) handover to the target cell. Here, the target cell configuration may be, for example, a bearer configuration (Bearer configuration) or a radio resource configuration (Cell group configuration, Radio resource configuration). Furthermore, the execution condition of CHO may be specified, for example, based on the relationship between the radio qualities (e.g., RSRP, RSRQ, SINR) of the source cell and the target cell. For example, the execution condition may be that the radio quality of the target cell becomes greater than the radio quality of the source cell by a predetermined (or specified) offset value, or that such a state continues for a predetermined (or specified) time. Alternatively, the execution condition may be specified with respect to the radio quality of either the source cell or the target cell. For example, the execution condition may be that the radio quality of the target cell becomes a predetermined (or specified) absolute value, or that such a state continues for a predetermined (or specified) time. The source radio station may simultaneously designate multiple target cells (candidates) to the mobile terminal 600 and notify each target cell (candidate) of an individual CHO execution condition and target cell setting. The multiple target cells may be multiple cells managed by one target radio station, or may be designated across multiple different target radio stations. On the other hand, when multiple target cells (candidates) are designated, the mobile terminal 600 may determine whether the notified CHO execution condition for each cell is satisfied, and perform handover to a target cell (candidate) that satisfies the CHO execution condition.

[0433] The acceptance information may include information about a target cell configuration for the conditional handover (CHO). As described above, the acceptance information may include the information about the target cell, and the information about the target cell may include information about a target cell configuration for the CHO, or they may be equivalent (i.e., replaced). This allows the condition information to be transmitted to the second radio station 500B.

[0434] Furthermore, as described above, the second radio station 500B (second communication processing unit 545) may transmit a message for executing the handover (for example, an RRC Reconfiguration message) to the mobile terminal 600, and the message for executing the handover may include the condition information. As a result, the condition information may be transmitted to the mobile terminal 600.

[0435] The mobile terminal 600 (communication control unit 633) may control the handover based on the condition information. For example, the mobile terminal 600 (communication control unit 633) may determine whether to perform random access to the target cell based on the condition information.

[0436] Such a conditional handover may, for example, allow the mobile terminal 600 to more reliably maintain a connection with the network.

[0437] The procedure for handover in the fourth aspect has been described above. If the message including the acceptance information is not transmitted to the second radio station 500B, as in the general procedure, the second radio station 500B transmits the request message for handover without knowing whether radio resources for the mobile terminal 600 are reserved in the first radio station 500A. Therefore, even if the request message is transmitted, radio resources may not be reserved and the mobile terminal 600 may not be able to communicate in the target cell during flight. On the other hand, if the message including the acceptance information is transmitted to the second radio station 500B as described above, the second radio station 500B can transmit the request message for handover after knowing that radio resources for the mobile terminal 600 are reserved in the first radio station 500A, or can start executing the handover without transmitting the request message. This allows the mobile terminal 600 to more reliably communicate in the target cell during flight. As a result, it may be easier to ensure the safety of the flight of the mobile terminal 600 and the safety of the crew on board the mobile terminal 600.

[0438] (2) Change of flight route (2-1) Determining whether radio resources are available in the first radio station As described above, for example, the first radio station 500A (control unit 541) determines whether radio resources for the mobile terminal 600 in the first radio station 500A can be secured.

[0439] For example, the first radio station 500A (control unit 541) determines whether the radio resources can be secured or whether the radio resources cannot be secured.

[0440] (2-2) Flight route change For example, the first wireless station 500A (first communication processing unit 543) changes the flight path of the mobile terminal 600 when the wireless resources cannot be secured.

[0441] The change in flight path is a change in the flight path of the mobile terminal 600 within the coverage area of the first wireless station 500A.

[0442] The changed flight path of the mobile terminal 600 may be called an alternative path, and the change in the flight path of the mobile terminal 600 may also be called the selection of an alternative path. The change in the flight path of the mobile terminal 600 (i.e., the selection of an alternative path) may also be called re-routing.

[0443] -First example As a first example, the change in flight path may be a change in the cell in which the mobile terminal 600 uses radio resources.

[0444] More specifically, for example, the change in the flight path does not include a change in the waypoint of the mobile terminal 600, but may be a change in the cell for which the mobile terminal 600 uses radio resources. As an example, when radio resources of a first cell in a first frequency band cannot be secured but radio resources of a second cell in the first frequency band or a second frequency band that geographically overlaps with the first cell can be secured, the cell for which the mobile terminal 600 uses radio resources is changed from the first cell to the second cell.

[0445] -Second example As a second example, the change in flight path may be a change in the waypoints of the mobile terminal 600 .

[0446] More specifically, a cell for which the mobile terminal 600 uses radio resources may also be changed in association with a change in the waypoint of the mobile terminal 600. As an example, when radio resources of a first cell (e.g., a cell in a first sector) cannot be secured but radio resources of a second cell (e.g., a cell in a second sector) geographically adjacent to the first cell can be secured, the waypoint of the mobile terminal 600 may be changed so that the mobile terminal 600 passes through the second cell instead of the first cell. Furthermore, the target cell (the second cell) after the change in the waypoint may use the same frequency band as the first cell or a different frequency band.

[0447] -Methods for changing flight routes (selecting detour routes) For example, the flight-related information may include not only the route information (information indicating the route of flight of the mobile terminal 600) but also detour route information indicating one or more detour routes for flight of the mobile terminal 600. The first radio station 500A (first communication processing unit 543) may select a detour route indicated by the detour route information. Such selection of a detour route may be called prepared re-routing.

[0448] Alternatively, the first wireless station 500A (first communication processing unit 543) may independently select a detour route. Such selection of a detour route may be called dynamic re-routing.

[0449] (2-3) Notification of flight route changes For example, when the first wireless station 500A (first communication processing unit 543) cannot secure the wireless resources, it triggers a process of notifying the second wireless station 500B of a change in the flight path of the mobile terminal 600.

[0450] -First example For example, the first wireless station 500A (first communication processing unit 543) may notify the second wireless station 500B of the change in the flight path by directly notifying the second wireless station 500B of the change in the flight path.

[0451] FIG. 24 is a sequence diagram for explaining a first example of notification of a change in flight path of the mobile terminal 600 according to the fourth embodiment.

[0452] If the first radio station 500A (target RAN node) cannot secure radio resources for the mobile terminal 600 at the first radio station 500A, it notifies the second radio station 500B (source RAN node) of a change in the flight path of the mobile terminal 600 (S1551).

[0453] The first wireless station 500A (target RAN node) transmits information (Re-routing Information) about a change in the flight path of the mobile terminal 600 to the CN 10 (S1561), and the CN 10 transmits the information (Re-routing Information) to the control device 100 (S1563).

[0454] The control device 100 updates the flight path information and transmits the updated flight path information as user plane data to the mobile terminal 600 via the CN 10 and the second wireless station 500B (S1565, S1567, S1569).

[0455] -Second example The first radio station 500A (first communication processing unit 543) may notify the second radio station 500B of the change in the flight path by notifying the first CN node 200, which notifies the second radio station 500B of the change in the flight path.

[0456] FIG. 25 is a sequence diagram for explaining a second example of notification of a change in flight path of the mobile terminal 600 according to the fourth embodiment.

[0457] If the first radio station 500A (target RAN node) cannot secure radio resources for the mobile terminal 600 at the first radio station 500A, it notifies the CN10 (first CN node 200) of a change in the flight path of the mobile terminal 600 (S1553).

[0458] The CN 10 (first CN node 200) notifies the second radio station 500B (source RAN node) of the change in flight path of the mobile terminal 600 (S1555).

[0459] Steps S1561 to S1569 are the same as the first example in Fig. 24. Therefore, duplicated explanations will be omitted here.

[0460] The notification in step S1553 and the transmission in step S1561 may be performed together. For example, based on the reception of the notification in step S1553, the CN 10 may start the process of step S1555 and the process of step S1561.

[0461] -Notification to the control device 100 For example, the control device 100 is notified of the change in the flight path of the mobile terminal 600 .

[0462] -First example For example, the first wireless station 500A (first communication processing unit 543) may notify the CN 10 of the change in the flight path, and the CN 10 may notify the control device 100 of the change in the flight path.

[0463] Specifically, for example, as described with reference to Figures 24 and 25, the first radio station 500A (target RAN node) transmits information (Re-routing Information) about a change in the flight path of the mobile terminal 600 to the CN10 (S1561), and the CN10 transmits the information (Re-routing Information) to the control device 100 (S1563).

[0464] -Second example After the handover, the mobile terminal 600 (communication processing unit 635) may notify the control device 100 of the change in the flight path of the mobile terminal 600.

[0465] FIG. 26 is a sequence diagram for explaining a second example of notification of a flight path change to the control device 100 according to the fourth embodiment.

[0466] When the first radio station 500A (target RAN node) cannot secure radio resources for the mobile terminal 600 in the first cell of the first radio station 500A, the first radio station 500A notifies the second radio station 500B (source RAN node) of a change in the flight path of the mobile terminal 600 (S1571). Note that the change in the flight path may indicate, for example, a second cell different from the first cell of the first radio station 500A.

[0467] The second wireless station 500B transmits a Handover Request message to the first wireless station 500A (S1573).

[0468] In response to receiving the Handover Request message, the first wireless station 500A transmits a Handover Request Acknowledge message to the second wireless station 500B (S1575).

[0469] In response to receiving the Handover Request Acknowledge message, the second radio station 500B transmits an RRC Reconfiguration message to the mobile terminal 600 (S1577).

[0470] The mobile terminal 600 performs random access to the target cell (the cell of the first radio station 500A) (S1579). Furthermore, the mobile terminal 600 transmits an RRC Reconfiguration Complete message to the first radio station 500A (S1581). As an example, the target cell is the cell included in the information indicating the flight route change notified in step S1571.

[0471] The first wireless station 500A and the CN 10 perform a path switch (S1583). The first wireless station 500A transmits a UE Context Release message to the second wireless station 500B (S1585).

[0472] The mobile terminal 600 transmits flight path update information (ie, information about changes to the flight path of the mobile terminal 600) as user plane data to the control device 100 via the second wireless station 500B and the CN 10 (S1587, S1589, S1591).

[0473] The change of flight path in the fourth aspect has been described above. By changing the flight path in this way, wireless resources can be secured even when wireless resources cannot be secured on the original flight path. Therefore, the mobile terminal 600 can communicate more reliably during flight. As a result, it may be easier to ensure the flight of the mobile terminal 600 and the safety of the crew aboard the mobile terminal 600.

[0474] (3) Landing (3-1) Determining whether radio resources are available in the first radio station As described above, for example, the first radio station 500A (control unit 541) determines whether radio resources for the mobile terminal 600 in the first radio station 500A can be secured.

[0475] For example, the first radio station 500A (control unit 541) determines whether the radio resources can be secured or whether the radio resources cannot be secured.

[0476] (3-2) Notification of landing of mobile terminal 600 If the above-mentioned radio resources cannot be secured, the first radio station 500A (first communication processing unit 543) notifies the second radio station 500B or the first CN node 200 of the landing of the mobile terminal 600.

[0477] (a) Notice For example, the first radio station 500A (first communication processing unit 543) notifies the second radio station 500B or the first CN node 200 of the landing of the mobile terminal 600, and instructs or requests the second radio station 500B or the first CN node 200 to land the mobile terminal 600.

[0478] Alternatively, the first radio station 500A (first communication processing unit 543) may transmit auxiliary information to the second radio station 500B or the first CN node 200 as notification of the landing of the mobile terminal 600, the auxiliary information being used to determine whether to allow the mobile terminal 600 to land.

[0479] (b) Notification to the second wireless station 500B For example, when the first radio station 500A (first communication processing unit 543) cannot secure the radio resources, it notifies the second radio station 500B of the landing of the mobile terminal 600.

[0480] For example, in response to the notification of the landing of the mobile terminal 600 from the first wireless station 500A, the second wireless station 500B (first communication processing unit 543) notifies the mobile terminal 600 of the landing of the mobile terminal 600. For example, as the notification of the landing of the mobile terminal 600, the second wireless station 500B (first communication processing unit 543) instructs or requests the mobile terminal 600 to land.

[0481] For example, the mobile terminal 600 (flight control unit 631) controls the landing of the mobile terminal 600 in response to the notification of the landing of the mobile terminal 600 from the second wireless station 500B.

[0482] -Notification to control equipment For example, the control device 100 may be notified that the mobile terminal 600 has landed.

[0483] --First example For example, the first wireless station 500A (first communication processing unit 543) may notify the CN 10 of the landing of the mobile terminal 600, and the CN 10 may notify the control device 100 of the landing of the mobile terminal 600.

[0484] FIG. 27 is a sequence diagram for explaining a first example of a process for landing of the mobile terminal 600 according to the fourth embodiment.

[0485] When the first wireless station 500A is unable to secure wireless resources for the mobile terminal 600 at the first wireless station 500A, the first wireless station 500A notifies the second wireless station 500B of the landing of the mobile terminal 600 (S1601).

[0486] The first wireless station 500A notifies the CN 10 of the landing of the mobile terminal 600 (S1603), and the CN 10 notifies the control device 100 of the landing of the mobile terminal 600 (S1607).

[0487] In response to the notification of the landing of the mobile terminal 600 from the first wireless station 500A, the second wireless station 500B transmits an RRC Connection Release message including a landing instruction to the mobile terminal 600 (S1611).

[0488] The mobile terminal 600 transmits an Acknowledge message in response to the RRC Connection Release message to the second radio station 500B (S1621).

[0489] The mobile terminal 600 lands (S1623).

[0490] The second wireless station 500B performs UE Context Release (S1625).

[0491] --Second example The second wireless station 500B (first communication processing unit 543) may notify the CN 10 of the landing of the mobile terminal 600, and the CN 10 may notify the control device 100 of the landing of the mobile terminal 600.

[0492] FIG. 28 is a sequence diagram for explaining a second example of the process for landing of the mobile terminal 600 according to the fourth embodiment.

[0493] In the second example, unlike the first example of FIG. 26, the second wireless station 500B notifies the CN 10 of the landing of the mobile terminal 600 (S1605).

[0494] Other processing in the second example is the same as the processing in the first example of Fig. 26. Therefore, duplicated explanations will be omitted here.

[0495] --Third example The mobile terminal 600 (communication processing unit 635) may notify the control device 100 of the landing of the mobile terminal 600.

[0496] FIG. 29 is a sequence diagram for explaining a third example of the process for landing of the mobile terminal 600 according to the fourth embodiment.

[0497] In this third example, unlike the first example of Figure 26 and the second example of Figure 27, the mobile terminal 600 uses user plane data to notify the control device 100 of the landing of the mobile terminal 600 via the second radio station 500B and CN10 (S1613, S1615, S1617).

[0498] Other processing in the third example is the same as the processing in the first example in Fig. 26 and the second example in Fig. 27. Therefore, overlapping explanations will be omitted here.

[0499] (c) Notification to the first CN node 200 For example, if the above-mentioned radio resources cannot be secured, the first radio station 500A (first communication processing unit 543) notifies the first CN node 200 of the landing of the mobile terminal 600.

[0500] As a first example, in response to notification of the landing of the mobile terminal 600 from the first radio station 500A, the first CN node 200 (communication processing unit 233) notifies the mobile terminal 600 of the landing of the mobile terminal 600 via the second radio station 500B. For example, the first CN node 200 (communication processing unit 233) instructs or requests the mobile terminal 600 to land, as notification of the landing of the mobile terminal 600. For example, the first CN node 200 (communication processing unit 233) notifies the mobile terminal 600 of the landing of the mobile terminal 600 via the second radio station 500B using an NAS (Non Access Stratum) message.

[0501] As a second example, the first CN node 200 (communication processing unit 233) may notify the second radio station 500B of the landing of the mobile terminal 600 in response to the notification of the landing of the mobile terminal 600 from the first radio station 500A. The first CN node 200 (communication processing unit 233) may instruct or request the second radio station 500B to land the mobile terminal 600 as the notification of the landing of the mobile terminal 600. The second radio station 500B (first communication processing unit 543) may notify the mobile terminal 600 of the landing of the mobile terminal 600 in response to the notification of the landing of the mobile terminal 600 from the first CN node 200. The second radio station 500B (first communication processing unit 543) may instruct or request the mobile terminal 600 to land the mobile terminal 600 as the notification of the landing of the mobile terminal 600.

[0502] As a third example, in response to the notification of the landing of the mobile terminal 600 from the first wireless station 500A, the CN10 may notify the control device 100 of the landing of the mobile terminal 600. In response to the notification of the landing of the mobile terminal 600 from the CN10, the control device 100 (communication processing unit 133) may notify the mobile terminal 600 of the landing of the mobile terminal 600. As the notification of the landing of the mobile terminal 600, the control device 100 (communication processing unit 133) may instruct or request the mobile terminal 600 to land.

[0503] For example, the mobile terminal 600 (flight control unit 631) controls the landing of the mobile terminal 600 in response to the notification of the landing of the mobile terminal 600.

[0504] -Processing flow (notification from first CN node 200) FIG. 30 is a sequence diagram for explaining a fourth example of the process for landing of the mobile terminal 600 according to the fourth embodiment.

[0505] If the first wireless station 500A is unable to secure wireless resources for the mobile terminal 600 at the first wireless station 500A, it notifies the CN 10 (first CN node 200) of the landing of the mobile terminal 600 (S1631).

[0506] In response to notification of the landing of the mobile terminal 600 by the first radio station 500A, the CN10 (first CN node 200) notifies the mobile terminal 600 of the landing of the mobile terminal 600 via the second radio station 500B using an NAS message (S1641, S1643).

[0507] The mobile terminal 600 notifies the control device 100 of the landing of the mobile terminal 600 by using user plane data via the second wireless station 500B and the CN 10 (S1645, S1647, S1649).

[0508] The mobile terminal 600 notifies the second wireless station 500B of the landing of the mobile terminal 600 (S1661).

[0509] The second radio station 500B transmits an RRC Connection Release message to the mobile terminal 600 (S1663).

[0510] The mobile terminal 600 lands (S1665).

[0511] The second wireless station 500B performs UE Context Release (S1667).

[0512] -Processing flow (notification from control device 100) FIG. 31 is a sequence diagram for explaining a fifth example of the process for landing of the mobile terminal 600 according to the fourth embodiment.

[0513] 30, the CN10 notifies the control device 100 of the landing of the mobile terminal 600 in response to the notification of the landing of the mobile terminal 600 from the first wireless station 500A (S1653). Furthermore, the control device 100 notifies the mobile terminal 600 of the landing of the mobile terminal 600 by using user plane data via the CN10 and the second wireless station 500B (S1653, S1655, S1657).

[0514] Other processing in the fifth example is the same as the processing in the fourth example of Fig. 30. Therefore, duplicated explanations will be omitted here.

[0515] (3-3) Landing point For example, the landing of the mobile terminal 600 is the landing of the mobile terminal 600 at a landing point.

[0516] For example, the flight path information includes information indicating the landing point, and the mobile terminal 600 (flight control unit 631) lands at the landing point based on the flight path information.

[0517] Alternatively, the second radio station 500B (control unit 541) may determine the landing point. The mobile terminal 600 (flight control unit 631) may land at the landing point determined by the second radio station 500B.

[0518] Alternatively, the mobile terminal 600 (flight control unit 631) may determine the landing point. The mobile terminal 600 (flight control unit 631) may land at the landing point determined by itself. The mobile terminal 600 (flight control unit 631) may determine the landing point based on predetermined conditions. Information about the predetermined conditions may be included in the flight path information, or may not be included in the flight path information and may be provided separately by the second radio station 500B or the control device 100.

[0519] The landing of the mobile terminal 600 in the fourth aspect has been described above. According to such a landing, even when radio resources cannot be secured, it is possible to land the mobile terminal 600 safely. Therefore, it may be easier to ensure the flight of the mobile terminal 600 and the safety of the crew aboard the mobile terminal 600.

[0520] <<8. Fifth Aspect>> Next, a fifth aspect of the present disclosure will be described with reference to Figures 32 to 34. The above-described first aspect is a specific aspect, but the fifth aspect is a more generalized aspect, particularly with regard to transmission and reception of capability information.

[0524] CN node 250 may include a network adapter, a network interface card, a transmitter, a receiver, and / or a transceiver, etc. Additionally, CN node 250 may include a hard disk.

[0526] The CN node 250 may include a transceiver and a controller. The controller may perform the operations of the communication processor 251 and may send and receive information or messages via the transceiver.

[0527] The CN node 250 may be virtualized. That is, the CN node 250 may be implemented as a virtual machine. In this case, the CN node 250 (virtual machine) may operate as a virtual machine on a physical machine (hardware) including a processor, memory, etc., and on a hypervisor.

[0528] <8.2. Radio Station Configuration> 33 is a block diagram showing an example of a schematic configuration of a wireless station 550 according to the fifth aspect. Referring to FIG.

[0529] (1) Communication processing unit 551 The communication processing unit 551 communicates with other nodes (for example, CN nodes). The specific operation of the communication processing unit 551 will be described later.

[0530] (2) Implementation example The communication processing unit 551 may be implemented by one or more processors and memories. The memory may be included in the one or more processors or may be external to the one or more processors. The communication processing unit 551 may be implemented by a controller, which may include one or more processors and memories.

[0532] The wireless station 550 may include a memory that stores a program (one or more instructions) and one or more processors that can execute the program (the one or more instructions). The one or more processors may execute the program to perform the operations of the communication processing unit 551. The program may be a program that causes a processor to perform the operations of the communication processing unit 551.

[0533] The wireless station 550 may include a transceiver and a controller. The controller may perform the operations of the communication processor 551 and may transmit and receive information or messages via the transceiver.

[0534] The wireless station 550 may be partially or entirely virtualized. That is, part or all of the wireless station 550 may be implemented as a virtual machine. In this case, part or all of the wireless station 550 (virtual machine) may operate as a virtual machine on a physical machine (hardware) including a processor, a memory, etc., and a hypervisor.

[0535] <8.3. Mobile Terminal Configuration> 34 is a block diagram showing an example of a schematic configuration of a mobile terminal 650 according to the fifth aspect. Referring to FIG.

[0536] (1) Communication processing unit 651 The communication processing unit 651 communicates with other nodes (for example, wireless stations). The specific operation of the communication processing unit 651 will be described later.

[0537] (2) Implementation example The communication processing unit 651 may be implemented by one or more processors and memories. The memory may be included in the one or more processors or may be external to the one or more processors. As an example, the communication processing unit 651 may be implemented in an SoC. The communication processing unit 651 may be implemented by a controller, which may include one or more processors and memories.

[0538] The mobile terminal 650 may include an antenna, radio frequency (RF) circuitry, a transmitter, a receiver, and / or a transceiver for wireless communication. Additionally, the mobile terminal 650 may include a hard disk.

[0539] The mobile terminal 650 may include a memory that stores a program (one or more instructions) and one or more processors that can execute the program (the one or more instructions). The one or more processors may execute the program to perform the operations of the communication processing unit 651. The program may be a program that causes a processor to perform the operations of the communication processing unit 651.

[0540] The mobile terminal 650 may include a transceiver and a controller. The controller may perform the operations of the communication processor 651 and may transmit and receive information or messages via the transceiver.

[0541] In addition, when the mobile terminal 650 is not a device attached to a flying device but is the flying device itself, the mobile terminal 650 may further include a flying unit, which may be implemented by a battery, a motor, an ESC, etc.

[0542] <8.4. Example of operation> The wireless station 550 (communication processing unit 551) transmits first capability information indicating whether the wireless station 550 supports operation for flight management of a manned air vehicle capable of flying using a wireless communication network (e.g., a wireless communication network using the 3GPP standard) to the CN node 250. The CN node 250 (communication processing unit 251) receives the first capability information from the wireless station 550. Note that the mobile terminal 690 (communication processing unit 651) communicates with the wireless station 550.

[0543] For example, the transmission and reception of the first capability information in the fifth aspect is similar to the transmission and reception of the first capability information in the first aspect, so a redundant description will be omitted here.

[0544] However, the transmission and reception of the first capability information in the fifth aspect is not limited to the same example as in the first aspect.

[0545] The transmission and reception of capability information according to the fifth aspect has been described above. When the first capability information is not transmitted from the radio station 550 to the first CN node 250, the first CN node 250 may request information for flight management (e.g., resource information) from the radio station 550, regardless of whether the radio station 550 supports the operation of the radio station 550 for flight management of a manned air vehicle capable of flying using a wireless communication network (e.g., a wireless communication network using the 3GPP standard). If the radio station 550 is unable to provide the information for flight management, the request for the information for flight management is wasted. Therefore, unnecessary signaling may occur during the transmission and reception of the information for flight management, resulting in the waste of communication resources and the processing resources of each node. On the other hand, when the first capability information is transmitted from the radio station 550 to the first CN node 250 as described above, the first CN node 250 may determine whether the radio station 550 supports the operation of the radio station 550 for flight management of a manned air vehicle capable of flying using a wireless communication network (e.g., a wireless communication network using the 3GPP standard). This avoids the occurrence of unnecessary signaling, thereby avoiding the waste of communication resources and processing resources of each node.

[0546] <<9. Sixth Aspect>> Next, a sixth aspect of the present disclosure will be described with reference to Figures 35 to 39. The above-described first aspect is a specific aspect, but the sixth aspect is a more generalized aspect, particularly with regard to transmission and reception of resource information.

[0548] (1) Communication processing unit 161 The communication processing unit 161 communicates with other nodes (for example, CN nodes). The specific operation of the communication processing unit 161 will be described later.

[0549] (2) Implementation example The communication processing unit 161 may be implemented by one or more processors and memories. The memory may be included in the one or more processors or may be external to the one or more processors. The communication processing unit 161 may be implemented by a controller, and the controller may include one or more processors and memories.

[0550] The control device 160 may include a network adapter, a network interface card, a transmitter, a receiver, and / or a transceiver, etc. Additionally, the control device 160 may include a hard disk.

[0551] The control device 160 may include a memory that stores a program (one or more instructions) and one or more processors that can execute the program (one or more instructions). The one or more processors may execute the program to perform the operation of the communication processing unit 161. The program may be a program that causes a processor to perform the operation of the communication processing unit 161.

[0552] The control device 160 may include a transceiver and a controller. The controller may perform the operations of the communication processing unit 161 and may send and receive information or messages via the transceiver.

[0555] (1) Communication processing unit 261 The communication processing unit 261 communicates with other nodes (for example, wireless stations or CN nodes). The specific operation of the communication processing unit 261 will be described later.

The communication processing unit 261 may be implemented by a controller, and the controller may include one or more processors and memories.

[0557] The first CN node 260 may include a network adapter, a network interface card, a transmitter, a receiver, and / or a transceiver, etc. Additionally, the first CN node 260 may include a hard disk.

[0558] The first CN node 260 may include a memory that stores a program (one or more instructions) and one or more processors that can execute the program (one or more instructions).

[0560] The first CN node 260 may be virtualized. That is, the first CN node 260 may be implemented as a virtual machine. In this case, the first CN node 260 (virtual machine) may operate as a virtual machine on a physical machine (hardware) including a processor, memory, etc., and a hypervisor.

[0561] <9.3. Configuration of the second core network node> 37 is a block diagram showing an example of a schematic configuration of a second CN node 360 according to the sixth aspect. Referring to FIG. 37, the second CN node 360 includes a communication processing unit 361.

[0562] (1) Communication processing unit 361 The communication processing unit 361 communicates with other nodes (for example, a CN node or a control device). The specific operation of the communication processing unit 361 will be described later.

[0563] (2) Implementation example The communication processing unit 361 may be implemented by one or more processors and memories. The memory may be included in the one or more processors or may be external to the one or more processors. The communication processing unit 361 may be implemented by a controller, and the controller may include one or more processors and memories.

[0564] The second CN node 360 may include a network adapter, a network interface card, a transmitter, a receiver, and / or a transceiver, etc. Additionally, the second CN node 360 may include a hard disk.

[0565] The second CN node 360 may include a memory that stores a program (one or more instructions) and one or more processors that can execute the program (one or more instructions). The one or more processors may execute the program to perform the operations of the communication processing unit 361. The program may be a program that causes a processor to perform the operations of the communication processing unit 361.

[0566] The second CN node 360 may include a transceiver and a controller. The controller may perform the operations of the communication processor 361 and may send and receive information or messages via the transceiver.

[0567] The second CN node 360 may be virtualized. That is, the second CN node 360 may be implemented as a virtual machine. In this case, the second CN node 360 (virtual machine) may operate as a virtual machine on a physical machine (hardware) including a processor, memory, etc., and a hypervisor.

[0568] <9.4. Radio Station Configuration> 38 is a block diagram showing an example of a schematic configuration of a wireless station 560 according to the sixth aspect. Referring to FIG.

[0569] (1) Communication processing unit 561 The communication processing unit 561 communicates with other nodes (for example, CN nodes). The specific operation of the communication processing unit 561 will be described later.

[0570] (2) Implementation example The description of an implementation example of the wireless station 560 according to the sixth aspect is the same as the description of the implementation example of the wireless station 550 according to the fifth aspect, except for the difference in reference numerals, and therefore, a duplicated description will be omitted here.

[0571] <9.5. Mobile Terminal Configuration> 39 is a block diagram showing an example of a schematic configuration of a mobile terminal 660 according to the sixth aspect. Referring to FIG.

[0572] (1) Communication processing unit 661 The communication processing unit 661 communicates with other nodes (for example, wireless stations). The specific operation of the communication processing unit 661 will be described later.

[0573] (2) Implementation example The description of an implementation example of the mobile terminal 660 according to the sixth aspect is the same as the description of the implementation example of the mobile terminal 650 according to the fifth aspect, except for the difference in the reference numerals, and therefore, a duplicated description will be omitted here.

[0574] <9.6. Example of operation> The radio station 560 (communication processing unit 561) transmits resource information regarding the availability of radio resources for at least one time period to the first CN node 260. The first CN node 260 (communication processing unit 261) receives the resource information from the radio station 560 and transmits the resource information to the second CN node 360. The second CN node 360 (communication processing unit 361) receives the resource information from the first CN node 260 and transmits the resource information to the control device 160, which generates or acquires flight path information for the mobile terminal. The control device 160 (communication processing unit 161) receives the resource information from the second CN node 360. The mobile terminal 660 (communication processing unit 661) communicates with the radio station 560.

[0575] For example, the transmission and reception of the resource information in the sixth aspect is the same as the transmission and reception of the resource information in the first aspect, so a duplicated description will be omitted here.

[0576] However, the transmission and reception of the resource information in the sixth aspect is not limited to the same example as in the first aspect.

[0577] The transmission and reception of resource information according to the sixth aspect has been described above. If the resource information is not transmitted to the control device 160, the control device 160 plans the flight of the mobile terminal 660 (for example, determines the flight path of the mobile terminal 660) without knowing whether wireless resources are likely to be available. This may make it difficult for the control device 160 to determine a flight path that will ensure wireless resources. On the other hand, if the resource information is transmitted to the control device 160 as described above, the control device 160 can know to some extent whether wireless resources are likely to be available, and therefore, it may be easier for the control device 160 to determine a flight path that will ensure wireless resources. As a result, it may be easier to determine a flight path that ensures the flight of the mobile terminal 660 and the safety of the crew aboard the mobile terminal 660.

[0594] The wireless station 570 may include a transceiver and a controller. The controller may perform the operations of the control unit 571 and the communication processing unit 573, and may transmit and receive information or messages via the transceiver.

[0595] The wireless station 570 may be partially or entirely virtualized. That is, part or all of the wireless station 570 may be implemented as a virtual machine. In this case, part or all of the wireless station 570 (virtual machine) may operate as a virtual machine on a physical machine (hardware) including a processor, memory, etc., and a hypervisor.

As an example, the flight control unit 671 and the communication processing unit 673 may be implemented in an SoC. The flight control unit 671 and the communication processing unit 673 may be implemented by a controller, which may include one or more processors and memories. As an example, the flight control unit 671 may be implemented by a flight controller. The communication processing unit 673 may be implemented by the flight controller or another controller.

[0600] The mobile terminal 670 may include an antenna, radio frequency (RF) circuitry, a transmitter, a receiver, and / or a transceiver for wireless communication. Additionally, the mobile terminal 670 may include a hard disk.

[0601] The mobile terminal 670 may include a memory that stores a program (one or more instructions) and one or more processors that can execute the program (the one or more instructions). The one or more processors may execute the program to perform the operations of the flight control unit 671 and the communication processing unit 673. The program may be a program that causes the processor to perform the operations of the flight control unit 671 and the communication processing unit 673.

[0602] The mobile terminal 670 may include a transceiver and a controller. The controller may perform the operations of the flight control unit 671 and the communication processing unit 673, and may transmit and receive information or messages via the transceiver.

[0603] In addition, when the mobile terminal 670 is not a device attached to a flying device but is the flying device itself, the mobile terminal 670 may further include a flying unit, which may be implemented by a battery, a motor, an ESC, etc.

[0604] <10.6. Example of operation> The mobile terminal 670 moves according to the flight path information.

[0605] The control device 170 (communication processing unit 171) transmits a first request message requesting the reservation of radio resources for the mobile terminal 670 to the core network connected to the radio station 570 that reserves the radio resources.

[0606] The second CN node 370 (communications processing unit 371) receives the first request message from the control device. In response to receiving the first request message, the second CN node 370 (communications processing unit 371) transmits a third request message requesting the reservation to the first CN node 270 or to a third CN node that transmits a further request message to the first CN node 270.

[0607] The first CN node 270 (communication processing unit 271) included in the core network transmits a second request message to the radio station 570 that reserves the radio resources, requesting the reservation of radio resources for the mobile terminal 670 that moves according to the flight path information.

[0608] The wireless station 570 (communication processing unit 573) receives the second request message from the first CN node. The wireless station 570 (control unit 571) performs the reservation in response to receiving the second request message.

[0609] The mobile terminal 670 (communication processing unit 673) communicates with the wireless station 560.

[0610] For example, the above-described operation of the seventh aspect is similar to the operation of the second aspect, and therefore, redundant explanations will be omitted here.

[0611] However, the above-described operation of the seventh aspect is not limited to the same example as the operation of the second aspect.

[0612] The seventh aspect has been described above. If reservation of radio resources for the mobile terminal 670 moving according to the flight route information is not requested, the radio resources will not be reserved, and it may be difficult for the mobile terminal 670 to communicate continuously during flight. As a result, it may be difficult to appropriately control the flight of the mobile terminal 670 from the outside. On the other hand, if reservation of radio resources for the mobile terminal 670 is requested in advance according to the flight route information as described above, the radio resources on the flight route of the mobile terminal 670 will be reserved in advance, making it easier for the mobile terminal 670 to communicate continuously during flight. As a result, it may be easier to ensure the flight of the mobile terminal 670 and the safety of the crew aboard the mobile terminal 670.

[0613] <<11. Eighth Aspect>> Next, an eighth aspect of the present disclosure will be described with reference to Figures 45 to 48. The above-described third aspect is a specific aspect, but the eighth aspect is a more generalized aspect. <11.1.

[0614] (1) Communication processing unit 181 The communication processing unit 181 communicates with other nodes (for example, CN nodes). The specific operation of the communication processing unit 181 will be described later.

[0615] (2) Implementation example The description of an implementation example of the control device 180 according to the eighth aspect is the same as the description of the implementation example of the control device 160 according to the sixth aspect, except for the difference in reference numerals. Therefore, the overlapping description will be omitted here.

[0616] <11.2. Configuration of the first core network node> 46 is a block diagram showing an example of a schematic configuration of a first CN node 280 according to the eighth aspect. Referring to FIG. 46, the first CN node 280 includes a control unit 281.

[0617] (1) Control Unit 281 The control unit 281 performs control in the first CN node 280. The specific operation of the control unit 281 will be described later.

[0618] (2) Implementation example The control unit 281 may be implemented by one or more processors and memory. The memory may be included within the one or more processors or may be external to the one or more processors. The control unit 281 may be implemented by a controller, which may include one or more processors and memory.

[0619] The first CN node 280 may include a network adapter, a network interface card, a transmitter, a receiver, and / or a transceiver, etc. Additionally, the first CN node 280 may include a hard disk.

[0620] The first CN node 280 may include a memory that stores a program (one or more instructions) and one or more processors that can execute the program (one or more instructions). The one or more processors may execute the program to perform the operations of the control unit 281. The program may be a program that causes the processor to perform the operations of the control unit 281.

[0621] The first CN node 280 may include a transceiver and a controller. The controller may perform the operations of the control unit 281 and may send and receive information or messages via the transceiver.

[0622] The first CN node 280 may be virtualized. That is, the first CN node 280 may be implemented as a virtual machine. In this case, the first CN node 280 (virtual machine) may operate as a virtual machine on a physical machine (hardware) including a processor, memory, etc., and a hypervisor.

[0623] <11.3. Configuration of the second core network node> 47 is a block diagram showing an example of a schematic configuration of a second CN node 380 according to the eighth aspect. Referring to FIG. 47, the second CN node 380 includes a communication processing unit 381.

[0624] (1) Communication processing unit 381 The communication processing unit 381 communicates with other nodes (for example, a CN node or a control device). The specific operation of the communication processing unit 381 will be described later.

[0625] (2) Implementation example The description of an example implementation of the second CN node 380 according to the eighth aspect is the same as the description of the example implementation of the second CN node 360 according to the sixth aspect, except for the difference in symbols. Therefore, a duplicated description will be omitted here.

[0626] <11.4. Mobile Terminal Configuration> 48 is a block diagram showing an example of a schematic configuration of a mobile terminal 680 according to the eighth aspect. Referring to FIG.

[0627] (1) Communication processing unit 681 The communication processing unit 681 communicates with other nodes (for example, wireless stations). The specific operation of the communication processing unit 681 will be described later.

[0628] (2) Implementation example The description of an implementation example of the mobile terminal 680 according to the eighth aspect is the same as the description of the implementation example of the mobile terminal 650 according to the fifth aspect, except for the difference in symbols, and therefore, redundant description will be omitted here.

[0629] <11.5. Example of operation> The control device 180 (communication processing unit 181) transmits a first request message to the core network requesting a call to the mobile terminal 680 for a flight of the mobile terminal 680 for which radio resources have been reserved.

[0630] The second CN node 380 (communications processing unit 381) receives the first request message. In response to receiving the first request message, the second CN node 380 (communications processing unit 381) transmits a second request message requesting the call to the first CN node 280 or to a third CN node that transmits a further request message to the first CN node 280.

[0631] The first CN node 280 (control unit 281) included in the core network performs the paging via the wireless station 580 in response to reception of the first request message in the core network.

[0632] The mobile terminal 680 (communication processing unit 681) transmits a message to the first CN node 280 requesting the start of communication for the flight of the mobile terminal 680 for which radio resources have been secured.

[0633] For example, the above-described operation of the eighth aspect is similar to the operation of the third aspect, and therefore, redundant explanations will be omitted here.

[0634] However, the above-described operation of the eighth aspect is not limited to the same example as the operation of the third aspect.

[0635] In this aspect, at least one of the mobile terminal 680 and the control device 180 requests the initiation of communication based on at least one of flight path information and flight-related information. This at least one of the flight path information and flight-related information is information that ensures that radio resources are secured along the flight path of the mobile terminal 680. Therefore, by requesting the initiation of communication based on this information, it may become easier for the mobile terminal 680 to communicate continuously during flight. As a result, it may become easier to ensure the flight of the mobile terminal 680 and the safety of the crew aboard the mobile terminal 680.

[0636] Also, for example, if a call to the mobile terminal 680 is not requested, the flight of the mobile terminal 680 is started autonomously by the mobile terminal 680. Therefore, it may be difficult for the control device 180 to control the flight of the mobile terminal 680 from the start. On the other hand, as explained in the eighth aspect, if a call to the mobile terminal 680 is requested, the flight of the mobile terminal 680 is started in response to a request from the network. Therefore, it becomes possible for the control device 180 to control the flight of the mobile terminal 680 from the start.

[0637] Also, as described in the eighth aspect, if the mobile terminal 680 sends a message to the first CN node 280 requesting the initiation of communications for the flight of the mobile terminal 680, the mobile terminal 680 will be able to communicate from the start of the flight.

[0638] <<12. Ninth Aspect>> Next, a ninth aspect of the present disclosure will be described with reference to Figures 49 to 51. The above-described fourth aspect is a specific aspect, but the ninth aspect is a more generalized aspect.

[0639] <12.1. Core network node configuration> 49 is a block diagram showing an example of a schematic configuration of a CN node 290 according to the ninth aspect. Referring to FIG. 49, the CN node 290 includes a control unit 291 and a communication processing unit 293.

The control unit 291 and the communication processing unit 293 may be implemented by the same processor, or may be implemented by different processors. The memory may be included in the one or more processors, or may be external to the one or more processors. The control unit 291 and the communication processing unit 293 may be implemented by a controller, and the controller may include one or more processors and memories.

[0643] CN node 290 may include a network adapter, a network interface card, a transmitter, a receiver, and / or a transceiver, etc. Additionally, CN node 290 may include a hard disk.

[0644] The CN node 290 may include a memory that stores a program (one or more instructions) and one or more processors that can execute the program (one or more instructions). The one or more processors may execute the program to perform the operations of the control unit 291 and the communication processing unit 293. The program may be a program that causes the processor to perform the operations of the control unit 291 and the communication processing unit 293.

[0645] The CN node 290 may include a transceiver and a controller. The controller may perform the operations of the control unit 291 and the communication processing unit 293, and may transmit and receive information or messages via the transceiver.

[0646] The CN node 290 may be virtualized. That is, the CN node 290 may be implemented as a virtual machine. In this case, the CN node 290 (virtual machine) may operate as a virtual machine on a physical machine (hardware) including a processor, memory, etc., and on a hypervisor. <12.2. Radio Station Configuration> 50 is a block diagram showing an example of a schematic configuration of a radio station 590 according to the ninth aspect. Referring to FIG. 50, the radio station 590 includes a control unit 591 and a communication processing unit 593.

[0647] (1) Control Unit 591 The control unit 591 performs control in the wireless station 590. The specific operation of the control unit 591 will be described later.

[0648] (2) Communication processing unit 593 The communication processing unit 593 communicates with other nodes (for example, CN nodes). The specific operation of the communication processing unit 593 will be described later.

[0649] (3) Implementation example The description of an implementation example of the wireless station 590 according to the ninth aspect is the same as the description of the implementation example of the wireless station 570 according to the seventh aspect, except for the differences in the reference numerals, and therefore, redundant description will be omitted here. <12.3. Mobile Terminal Configuration> 51 is a block diagram showing an example of a schematic configuration of a mobile terminal 690 according to the ninth aspect. Referring to FIG. 51, the mobile terminal 690 includes a flight control unit 691 and a communication processing unit 693.

[0650] (1) Flight Control Unit 691 The flight control unit 691 controls the flight of the mobile terminal 690. The specific operation of the flight control unit 691 will be described later.

[0651] (2) Communication processing unit 693 The communication processing unit 693 communicates with other nodes (for example, wireless stations). The specific operation of the communication processing unit 693 will be described later.

[0652] (3) Implementation example The description of an implementation example of the mobile terminal 690 according to the ninth aspect is the same as the description of the implementation example of the mobile terminal 670 according to the seventh aspect, except for the difference in the reference numerals. Therefore, the overlapping description will be omitted here.

[0653] <12.4. Example of operation> The mobile terminal 690 moves according to the flight path information.

[0654] The first wireless station 590A (control unit 591) controls the handover of the mobile terminal 690 from the second wireless station 590B to the first wireless station 590A in accordance with the flight path information. The first wireless station 590A (communication processing unit 593) causes the second wireless station 590B to transmit a message including information regarding acceptance of the handover, without receiving a request message for the handover transmitted from the second wireless station 590B.

[0655] The second radio station 590B (control unit 591) controls the handover of the mobile terminal 690 from the second radio station 590B to the first radio station 590A in accordance with the flight path information. The second radio station 590B (communication processing unit 593) receives a message including information regarding acceptance of the handover without transmitting a request message for the handover.

[0656] The CN node 290 (control unit 291) generates a request message for handover of the mobile terminal 690 from the second radio station 590B to the first radio station 590A in accordance with the flight path information. The CN node 290 (communication processing unit 293) transmits the request message to the first radio station 590A without receiving the request message from the second radio station 590B. The request message triggers the first radio station 590A to transmit a message including information regarding acceptance of the handover to the second radio station 590B without receiving the request message for handover transmitted from the second radio station 590B.

[0657] The mobile terminal 690 (flight control unit 691) controls the movement of the mobile terminal 600 in accordance with the flight route information. The mobile terminal 690 (communication processing unit 693) communicates with the second wireless station 590B.

[0658] For example, the above-described operation of the ninth aspect is similar to the operation of the fourth aspect, and therefore, redundant explanations will be omitted here.

[0659] However, the above-described operation of the ninth aspect is not limited to the same example as the operation of the fourth aspect.

[0660] The ninth aspect has been described above. For example, if the message including the acceptance information is not transmitted to the second radio station 590B, as in the general procedure, the second radio station 590B transmits the request message for handover without knowing whether radio resources for the mobile terminal 690 are reserved at the first radio station 590A. Therefore, even if the request message is transmitted, radio resources may not be reserved and the mobile terminal 690 may not be able to communicate in the target cell during flight. On the other hand, if the message including the acceptance information is transmitted to the second radio station 590B as described above, the second radio station 590B can transmit the request message for handover after knowing that radio resources for the mobile terminal 690 are reserved at the first radio station 590A, or can start executing the handover without transmitting the request message. Therefore, the mobile terminal 690 can more reliably communicate in the target cell during flight. As a result, it may be easier to ensure the safety of the flight of the mobile terminal 690 and the safety of the crew aboard the mobile terminal 690.

[0661] Although the embodiments of the present disclosure have been described above, the present disclosure is not limited to these embodiments.
