Description

Technical Field

[0001] The present disclosure relates to a method and an apparatus for controlling services of an unmanned aerial system (UAS) terminal by using a wireless communication system. Background Art

[0002] To meet the increasing demand for wireless data services after the commercialization of the fourth-generation (4G) communication system, considerable efforts have been made to develop a pre-fifth-generation (pre-5G) communication system or a 5G communication system. This is one of the reasons why the "5G communication system" or "pre-5G communication system" is called an "ultra 4G network communication system" or a "post-long term evolution (LTE) system". To achieve high data rates, the 5G communication system is being developed to be implemented in the super high frequency band (millimeter wave (mmWave)), such as a 60 GHz band. To reduce the path loss of radio waves in such a super high frequency band and to increase the transmission distance of radio waves in the 5G communication system, various technologies have been discussed and studied, such as beamforming, massive multiple-input multiple-output (MIMO), full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, and massive antennas. To improve the system network for the 5G communication system, various technologies have been developed, such as evolved small cells, advanced small cells, cloud radio access network (Cloud-RAN), ultra-dense network, device-to-device communication (D2D), wireless backhaul, mobile network, cooperative communication, coordinated multi-point (CoMP), and interference cancellation. In addition, for the 5G communication system, other technologies have been developed, such as hybrid frequency shift keying (FSK) and quadrature amplitude modulation (QAM) (FQAM) and sliding window superposition coding (SWSC) as advanced coding modulation (ACM) schemes, and filter bank multi-carrier (FBMC), non-orthogonal multiple access (NOMA), and sparse code multiple access (SCMA) as advanced access schemes.

[0003] The Internet has evolved from a human-based connection network where humans create and consume information to the Internet of Things (IoT) where distributed components such as objects exchange information with each other to process information. The Internet of Everything (IoE) technology is emerging, in which technologies related to IoT are combined with technologies such as those for processing big data through connection with cloud servers. To implement IoT, various technical components are required, such as sensing technology, wired / wireless communication and network infrastructure, service interface technology, security technology, etc. In recent years, technologies including sensor networks for connecting objects, machine-to-machine (M2M) communication, machine type communication (MTC), etc. have been studied. In the IoT environment, intelligent Internet technology (IT) services can be provided to collect and analyze data obtained from objects connected to each other to create new value in human life. As existing information technology (IT) technologies and various industries converge and combine with each other, IoT can be applied to various fields such as smart homes, smart buildings, smart cities, smart cars or connected cars, smart grids, healthcare, smart appliances, high-quality medical services, etc.

[0004] Various attempts are being made to apply 5G communication systems to IoT networks. For example, technologies related to sensor networks, M2M communication, MTC, etc. are being implemented by using 5G communication technologies including beamforming, MIMO, array antennas, etc. Cloud-RAN, as an application of the above big data processing technology, can be an example of the integration of 5G communication technology and IoT technology.

[0005] Since it is possible to provide various services as described above according to the development of wireless communication systems, there has emerged a need for a method of providing UAS services through wireless communication systems. Summary of the Invention

However, the present disclosure is not limited to the following terms, and other terms with equivalent technical meanings may be used.

[0066] For convenience of description, in the present disclosure, terms and names defined in the LTE and NR standards are used. The LTE and NR standards are the latest standards defined by the 3rd Generation Partnership Project (3GPP) organization among existing communication standards. However, the present disclosure is not limited by these terms and names and can be equally applied to systems conforming to other standards. In particular, the present disclosure can be applied to 3GPP NR (the 5th generation mobile communication standard).

Further, embodiments of the present disclosure can be applied to other communication systems with some modifications within a range that does not significantly deviate from the scope of the present disclosure as judged by those skilled in the art.

[0067] The object of the present disclosure is to define a method and device for a UAS (Unmanned Aerial System) service operator to define a serviceable area for a UAS subscriber terminal and control the terminal not to deviate from the service area. The object of the present disclosure is to define a method for a UAS operator to receive status information of a UAS terminal from a wireless communication system and manage the service area of the UAS terminal.

[0068] According to an embodiment of the present disclosure, before the terminal moves into a service restricted area, the UAS can preemptively control the UAS terminal based on the communication environment of the UAS terminal and the determination of the movement path of the UAS terminal.

[0069] Additionally, the object of the present disclosure is to define a method and device for a Unmanned Aerial System (UAS) service operator to define a serviceable area for a UAS subscriber terminal and control the terminal when the terminal has deviated from the service area.

[0070] According to an embodiment of the present disclosure, the UTM can determine the position of the UAS terminal by using a wireless communication system and can perform required control on the UAS terminal that has moved into an area where UAS services are not allowed by using the wireless communication system.

[0071] Figure 1 is a diagram showing the system structure for providing UAS services according to an embodiment of the present disclosure.

[0072] The UAS for providing UAS services may include at least one of the following: an unmanned aerial vehicle (UAV) and a UAV controller as elements constituting a Unmanned Aerial System (UAS), a radio access network (RAN) and a core network (CN) of a wireless communication system (or a mobile communication system), a UAS traffic management (UTM) for providing additional information to the UAS terminal and controlling operations, and a regulatory agency such as a government that provides flight control information. The UAS is not limited to the above examples, and the system for providing UAS services may include more than Figure 1More or fewer components than those shown, and the operation or function of at least one component may be provided by different components.

[0073] According to an embodiment of the present disclosure, the UAV 122 may include various flying devices, such as aircraft, vehicles, and aircraft capable of providing UAS services. For example, the UAV may include airplanes, helicopters, drones, robots, etc., and is not limited to the above examples, and may include flying devices capable of providing services within an operable area, regardless of its form or structure.

[0074] According to an embodiment of the present disclosure, the UAV controller 121 may control at least one UAV. For example, the UAV controller may control the position, flight, route, speed, etc. of the UAV. The UAV controller is not limited to the above examples.

[0075] According to an embodiment of the present disclosure, the radio access network (RAN) 130 and the core network (CN) 140 may respectively refer to configurations included in a wireless communication network. The RAN 130 may be a configuration responsible for the wireless connection to a wireless terminal (e.g., a UAV). For example, the RAN 130 may be a base station. The base station may include an LTE base station (e.g., an eNodeB) or an NR base station (gNodeB).

[0076] In addition, the core network (CN) 140 may include network elements that process data received from a wireless terminal through the RAN and provide a connection to other networks, and may include a 5G core network, an evolved packet system (EPS), etc.

[0077] According to an embodiment of the present disclosure, a wireless communication system (or a wireless communication network) may refer to a mobile communication system (or a mobile communication network). In addition, the wireless communication system may include a RAN and a CN.

[0078] According to an embodiment of the present disclosure, the components included in Figure 1 the UAS service system may be network functions. In addition, the network function may be referred to as a network entity. The components are not limited to the above examples, and may be separate configurations other than network functions.

[0079] Refer to Figure 1, UTM 110 can be a configuration for tracking and managing the registration and movement of each of the UAS terminals 120, namely the UAV 121 and the UAV controller 122. UTM 110 can periodically or when a certain condition is met collect information about the location change of the UAS terminal from the UAS terminal and the wireless communication network (e.g., RAN 130, CN 140), and can perform operations required to control the UAV 122. For example, when the terminal has left the permitted flight area or returned to the permitted area, it can order the terminal to stop flying in consideration of the flight control information specified by the regulatory authority 150.

[0080] In addition, according to an embodiment of the present disclosure, UTM 110 can deliver information related to the no-fly zone of the UAS terminal 120 to the UAS terminal 120 and the wireless communication system (e.g., RAN or CN) in advance or during the service through the registration process of the terminal or a separate message. In a method of restricting the service area of the terminal based on the information about the no-fly zone, the prior control through UTM110 can be restricted until the UAS terminal 120 moves into the no-fly zone.

[0081] Figure 2 A method of providing a UAS service according to an embodiment of the present disclosure is shown.

[0082] According to an embodiment of the present disclosure, a method of being controlled by UTM 210 is implemented before the UAS terminal 240 moves into a no-fly zone in a state where the UAS terminal 240 is controllable by using a wireless communication system.

[0083] According to an embodiment of the present disclosure, UTM 210 can provide information about the no-fly zone (no-fly zone information) to the UAS terminal 240. For example, UTM 210 can provide information about the no-fly zone to the UAS terminal 240 through the wireless communication network (CN 220 and RAN 230) (operation 2), or can provide information about the no-fly zone by using a different method (e.g., a UAS application) (operation 1). However, according to the implementation, operation 1 of providing information about the no-fly zone by using a different method can be omitted.

[0084] According to an embodiment of the present disclosure, UTM 210 can deliver information about the no-fly zone of the UAS terminal 240 to the CN 220 of the wireless communication system (operation 2). CN 220 can configure the UAS service restriction area information (e.g., information about the UAS service area) in the wireless communication system based on the information about the no-fly zone received from UTM 210, and deliver the information to RAN 230 (operation 3).

[0085] According to an embodiment of the present disclosure, the UAS service restricted area information may be a TAI (Tracking Area Identifier) or a cell ID. The UAS service restricted area information is not limited to the above examples, and the UAS service restricted area information may include any type of information that can identify the UAS service restricted area.

[0086] That is, the CN 220 can identify which cell or which tracking area the no-fly zone corresponds to, generate (or configure) the UAS service restricted area information as the identified information, and provide the UAS service restricted area information to the RAN 230.

[0087] According to an embodiment of the present disclosure, in the process of determining whether to perform a handover (operation 4: measurement) based on the channel quality information included in the measurement report received from the terminal, the RAN 230 may perform an operation of selecting a target cell for handover considering the current cell ID of the terminal, GPS location information, UAS service restricted area information, etc.

[0088] According to an embodiment of the present disclosure, when the channel quality information received from the terminal is maintained at or below a reference value and there is no alternative cell within the UAS serviceable area, the RAN 230 may deliver a warning message indicating a possible loss of communication with the UAS terminal 240 to the UTM 210 via the CN 220, and thus control is required (operation 5: warning report).

[0089] According to an embodiment of the present disclosure, when receiving the warning message, the UTM 210 may deliver a warning message about the UAS service restricted area to the UAS terminal 240. Additionally, when necessary, the UTM 210 may perform necessary controls such as flight control and remote control on the UAS terminal 240 (e.g., UAV). According to the implementation, the transmission of the warning message may be initiated by the RAN 230 considering the current movement path and speed of the terminal.

[0090] Figure 3 Illustrates an operation of delivering information about a no-fly zone to a terminal and a wireless communication system during an initial access process of a UAS terminal according to an embodiment of the present disclosure. Figure 3 The operation of delivering information about the no-fly zone is an example of the present disclosure, and the name of the message, the transmission order of the message, etc. may be changed according to the implementation.

[0091] According to an embodiment of the present disclosure, the UAV 301 and the UAV controller (UAC) terminal 302 may perform an initial registration process for communication services through a wireless communication network. Refer to Figure 3, in operation 311, the UAV 301 may send a registration request to the AMF 304. In operation 312, the UAC 302 may send a registration request to the AMF 304, and the UAV 301 and the UAC 302 may perform an initial registration process together with network entities in the CN such as the AMF (Access and Mobility Management Function) 304, the Policy Control Function (PCF) 305, and the Unified Data Management (UDM) 306, and perform an authorization process (e.g., 3GPP authentication / authorization).

[0092] When the authorization process of operation 313 is successfully executed, the radio communication network determines that the terminal is a UAS terminal (UAV 301 or UAC 302) based on the UE type information sent by the terminal via the registration request message or the UE type information of the subscription information registered to the terminal. Refer to Figure 3 , in operation 314, the AMF 304 may obtain subscription data by exchanging UE registration request / response messages with the UDM, and the UE type information may be included in the subscription data.

[0093] The radio communication network may determine to additionally perform an additional authorization process for flight approval and UAS service authorization with the UTM with respect to the UAS type terminal (e.g., UAV), and control the UAS terminal (e.g., UAV 301, UAC 302) to perform the necessary additional authorization process with the UTM 308. Refer to Figure 3 , in operation 315, the AMF 304 may determine whether the UAS type terminal will perform an additional authorization process with the UTM (decide additional authorization with the UTM), and based on the determination result, control the UAV 301 and the UTM 308 to perform the additional authorization process.

[0094] When the UAS terminal is successfully authorized and the service becomes available, the UTM 308 may configure information about the no-fly zone (or permitted flight zone) of the UAS terminal and deliver the information to the radio communication system and the terminal. Refer to Figure 3 , in operation 317, the UTM 308 may determine, judge, or identify the no-fly zone (decide the no-fly zone) based on the information received from the regulatory authority and the configuration information, weather / traffic information, etc. The UTM 308 may deliver the identified information to the radio communication system. The information about the no-fly zone may be expressed as, for example, geographical information such as location and longitude, administrative region information, or location information used in other aviation systems.

[0095] In addition, the UTM 308 may deliver the information about the no-fly zone of the terminal to the UDM 306 and the PCF 305. The UTM 308 may deliver the information about the no-fly zone to the UDM 306 and the PCF 305. Refer to Figure 3, in operation 318, the UTM 308 may provide information about the no - fly zone to the UDM and the PCF via an update message.

[0096] The AMF 304 may configure information about the UAS serviceable area (or UAS service restriction area) of the terminal based on the information about the no - fly zone of the terminal received from the UDM 306 and the PCF 305 during the process of completing the registration process of the terminal, and deliver the above - mentioned information to the RAN and the terminal via a registration approval message.

[0097] Reference Figure 3 , in operation 319, the AMF 304 may send or receive a UE registration request / response message from the UDM 306 and send or receive an MM policy request / response message from the PCF. At least one of the UE registration response message and the MM policy response message may include UAS serviceable area information.

[0098] According to an embodiment of the present disclosure, the PCF 305 (or the network exposure function (NEF) 307) may generate (or configure) UAS serviceable area information based on the information about the no - fly zone received from the UTM 308. The PCF 305 (or the NEF 307) may send the generated UAS serviceable area information to the AMF 304.

[0099] In addition, according to an embodiment of the present disclosure, the UAS serviceable area information may be a tracking area identifier (TAI) or a cell ID. The UAS serviceable area information is not limited to the above examples, and the UAS serviceable area information may include any type of information that can be used in a wireless communication network and can identify the UAS service restriction area.

[0100] According to an embodiment of the present disclosure, the AMF 304 may send UAS serviceable area information to the RAN 303. In operation 320, the AMF 304 may send the serviceable area information to the RAN 303 during the process of delivering a registration acceptance message to the UAV. In addition, in operation 321, the RAN 303 may send the serviceable area information to the UAV 301 by delivering the registration acceptance message received from the AMF to the UAV 301.

[0101] Figure 4 A method for controlling a UAS service area according to the signal quality of a terminal and the change of the terminal's position according to an embodiment of the present disclosure is shown. Figure 4 The method for controlling the UAS service area according to the signal quality and position change of the terminal is an example of the present disclosure, and the name of the message, the compound name of the message, the transmission order of the message, etc. may be changed according to the implementation.

[0102] The UAS terminal can perform an operation of sending measurement values (measurement reports) on the received channel quality to the RAN according to the period and conditions set by the wireless communication system. Refer to Figure 4 , in operation 411, the UAS terminal (UAV 401 or UAC402) can send a measurement report. The measurement report can include a cell list, SINR values, etc. The measurement report is not limited to the above examples.

[0103] The RAN 403 compares the channel quality measurement values received from the terminal with the handover reference value to determine whether to hand over to another cell. Refer to Figure 4 , in operation 412, the RAN 403 can determine whether there is an available cell for handover, and in operation 413, the RAN 403 can determine whether the signal quality has dropped to or below a certain threshold. This disclosure is not limited to the above examples.

[0104] In the case where the channel quality continues to drop to or below the set value (e.g., the handover reference value) when the terminal is flying in an adjacent cell (location) of the no-fly zone (or in a border cell of the permitted flight area), and there is no alternative cell in the permitted flight area, the RAN can deliver a warning message including information such as the current location of the terminal and the communication state of the terminal to the AMF, so as to alarm the UTM that the communication connection for the flight control of the terminal may be lost or the terminal may enter the no-fly zone. Refer to Figure 4 , in operation 414, the RAN 403 can send a warning report to the AMF, and the warning report can include the UE ID, cell ID, etc. This disclosure is not limited to the above examples.

[0105] The AMF 404 can deliver the information of the warning message received from the RAN to the PCF. Refer to Figure 4 , in operation 415, the AMF 404 can send a warning report to the PCF 405, and the warning report can include the UE ID, cell ID, etc. This disclosure is not limited to the above examples.

[0106] The PCF 405 can check the flight policy of the terminal, and when a violation is confirmed (or predicted), the PCF 405 can deliver the current location and warning status of the terminal to the UTM 408 through the NEF and AF 407 so that the UTM 408 can take necessary actions before the communication with the terminal is disconnected. Refer to Figure 4 , in operation 416, the PCF 405 can send a warning report to the UTM 408. The warning report can be sent to the UTM 408 via the NEF and AF 407, and in addition to the UE ID and cell ID, it can also include the location information format used by the UTM, such as geographical information or administrative information corresponding to the cell ID. This disclosure is not limited to the above examples.

[0107] The UTM 408 can examine the communication status and travel route of a terminal based on information received from a wireless communication system, and deliver a message for controlling the UAV 401 to the UAV 401 and the UAV controller terminal (UAC) 402. Depending on the situation, the UTM 408 delivers necessary control information to the UAV 401 and the UAV controller (UAC) terminal 402 via the wireless communication system, such as commanding the UAV terminal 401 to detour before entering a no-fly zone, forcing the UAV terminal 401 to land, or make a turning flight at a certain position. Refer to Figure 4 , in operation 417, the UTM 408 can deliver a UAS control overload message to the UAV 401 or the UAC 402, and the UAS control overload message can include orientation, an authentication code (auth code), a control code, etc. The present disclosure is not limited to the above examples.

[0108] Therefore, according to an embodiment of the present disclosure, a method and apparatus for allowing the UTM 408 to perform necessary control on UAS terminals 401 and 402 (e.g., UAV 401, UAC 402) via a wireless communication system before the UAS terminals move into a no-fly zone. According to the present disclosure, when the quality of a communication channel drops to or below a set value in a situation where a terminal is flying at a position adjacent to a no-fly zone, a warning message is sent to the UTM 408 via the wireless communication system so that the UTM 408 can perform necessary control on the UAS terminals 401 and 402 in a controllable environment regarding the UAS terminals 401 and 402.

[0112] According to an embodiment of the present disclosure, the data session can include a PDU session, and the PDU session can be a dedicated session for sending or receiving a UAS control message of the UTM 110.

[0113] In addition, according to an embodiment of the present disclosure, a data session for sending or receiving UAS control messages may be established by a PDU session identifier that is distinguishable from other data sessions. The PDU session identifier may be a DNN or S-NSSAI indicating a certain slice or a separately reserved indicator. In addition, the data session for sending or receiving UAS control messages may be a data session using a separate port.

[0114] In addition, according to an embodiment of the present disclosure, a data session for sending or receiving UAS control messages may be established by a 5G QoS indicator (5QI) or a reserved QoS flow identifier (QFI) that is distinguishable from other sessions.

[0115] In addition, according to an embodiment of the present disclosure, a data session for sending or receiving UAS control messages may be established during the UE registration process for UAS services.

[0116] Additionally, according to an embodiment of the present disclosure, the data session for sending or receiving UAS control messages may be a data session that is not affected by the control of the service allowed area.

Specifically, the UTM 110 may deliver a NAS message including UAS control information to the CN 140, and may deliver the NAS message to the UAV 122 via the CN 140 and the RAN 130.

[0120] According to an embodiment of the present disclosure, a NAS message including UAS control information may be configured in a new format including UAS control information or may be configured in an existing NAS message format. In addition, the NAS message may include a container including UAS control information.

[0121] Figure 7 is a diagram for describing a method for delivering UAS control messages by using an emergency session function of a wireless communication system according to an embodiment of the present disclosure.

[0122] Reference Figure 7 ,UTM 110 can deliver UAS control messages of the UTM to the UAS terminal 122 that has moved outside the UAS service permitted area by utilizing the emergency session function of the wireless communication system.

[0123] According to an embodiment of the present disclosure, the UTM 110 can send a paging request for an emergency session to the CN 140. The UTM 110 can send UAS control messages to the UAV 122 through the emergency session. According to an embodiment of the present disclosure, a method for implementing UTM control by using a wireless communication system in a situation where communication is restricted because the UAS terminal has moved into a no-fly zone. Hereinafter, the method of sending UAS control messages described in Reference Figure 5 and Figure 6 will be described in more detail.

[0124] Figure 8 is a diagram for describing the process of receiving information on the UAS service area from the UTM according to an embodiment of the present disclosure and delivering information necessary for the management of the service area to the base station and the terminal.

[0125] Figure 8 shows the process of delivering information on the UAS service area from the UTM to the wireless communication system during the initial registration of the terminal or the UTM service initiation process. The wireless communication system calculates information necessary for the operation of the network and the terminal based on the UAS service area information provided by the UTM, and delivers this information to each network function and each UAS terminal to achieve necessary control.

[0126] In operation 811, the UTM can configure UAS service area information including geographical information such as latitude and longitude for each UAS terminal and deliver the UAS service area information to the application function (AF) / network exposure function (NEF) of the wireless communication system.

[0127] In operation 812, the AF / NEF can convert the UAS service area information into information such as a tracking area ID and a cell ID, which are parameters used in the corresponding wireless communication system, and store the information obtained through the conversion in a unified data repository (UDR) that stores subscriber information of the UAS terminal.

[0128] According to an embodiment of the present disclosure, when direct communication between the UTM and a user data manager (UDM) that manages subscriber information is permitted, the UTM may directly transmit UAS service area information to the UDM in operation 813, and the UDM may convert the received UAS service area information into location information of the corresponding wireless communication system and store it in the UDR in operation 814. That is, only one of operation 812 and operations 813 and 814 may be performed, or both operation 812 and operations 813 and 814 may be performed.

[0129] In operation 815, the access management function (AMF) may request subscriber information from the UDM with respect to the UAS terminal. In operation 816, the UDM may obtain subscriber information from the UDR through a subscriber information search request and response.

[0130] In operation 817, the stored UAS service area information may be delivered to the AMF together with other subscriber information for controlling wireless communication services, and may be used as service area information for controlling communication services of the UAS terminal.

[0131] In operation 818 , to update the UAS service area, the UTM may deliver the updated UAS service area information to a policy control function (PCF).

[0132] In operation 819, the PCF may convert the received UAS service area information into a communication service area of a corresponding UAS terminal regarding the wireless communication system and send it to the AMF through an MM policy update control message.

[0133] In operation 820, the AMF may deliver the communication service area information about the UAS terminal received through the above process to the base station and the terminal through a UE context update message and a registration accept (or UE configuration update) message, respectively.

[0134] In operation 821, the base station may perform an operation for blocking handover of a PDU session of the terminal when the terminal moves outside the service area based on the received service area information. The terminal selects and accesses a base station within the service-allowed area based on the received service area information. Regardless of the above-described operation of the terminal, there is a chance that the terminal may move to an area where UAS service is not permitted due to a malfunction of the terminal or reception of inaccurate information, and a method for operating a UAS terminal in such a situation is needed.

[0135] According to an embodiment of the present disclosure, Figure 8 The names of the messages shown are merely examples, and the messages are not limited to the message names. Figure 8 Only some of the operations are shown.

[0136] Figure 9 A method is shown for a UAS terminal according to an embodiment of the present disclosure to establish a PDU session for delivering control messages with respect to UAS Traffic Management (UTM) for delivering control messages and to receive control messages from the UTM outside a specified service area.

[0137] Figure 9 A reference is shown Figure 6 The detailed process of the method for delivering control messages of the UTM by using a PDU session described.

[0138] In operations 911 to 914, during the process of initiating a UAS service with the UTM after the connection to the wireless communication system is completed, each UAS terminal (UAV terminal or UAV controller terminal) may perform a process of establishing a separate PDU session to be used for sending UAS control messages to the UTM or receiving UAS control messages from the UTM. That is, the UAV terminal and the UAV controller terminal may each send a PDU session establishment request to the base station, and the base station may send a PDU session establishment request to the SMF.

[0139] According to an embodiment of the present disclosure, the PDU session establishment request message sent by the terminal to establish a PDU session to be used for sending or receiving UAS control messages includes type=UAS service value, which is specified to indicate that the message is set for the transmission of UAS control messages, and may additionally include information of the UTM to be accessed.

[0140] According to an embodiment of the present disclosure, the information of the UTM is information for specifying a UTM server, and may include at least one of information such as the IP address, TCP / UDP port, protocol type, etc. of the UTM server. The PDU session establishment process may be performed identically for each of the UAV and UAV controller terminals, and in Figure 9 For convenience of description, the description will focus on the operation of the UAV terminal.

[0141] When receiving a PDU session establishment request message set to type=UAS service from the UAS terminal in operation 915, the SMF may determine whether to accept the PDU session request for the UAS service based on the subscriber information of the UAS terminal, which is received from the UDM (or PCF).

[0142] In operations 916 to 917, the SMF may deliver the result of determining whether to accept the PDU session request for the UAS service to the terminal through a PDU session establishment response message. That is, the SMF may send a PDU session establishment response message to the base station, and the base station may send a PDU session establishment response message to the terminal.

[0143] According to an embodiment of the present disclosure, the subscriber information may include information about the UTM that allows the UAS terminal to use the UAS service, and may be used as a criterion for determining whether to allow the UTM information received from the terminal. Additionally, the PDU session establishment response message may include at least one of a QoS flow ID and packet filtering information to be used by the UAS terminal to send and receive UAS control messages to and from the UTM.

[0144] According to an embodiment of the present disclosure, the packet filtering information is information for restricting packets that can be sent or received using the QoS flow ID, and includes at least one piece of information from among a source IP address, a source port, a destination IP address, a destination port, and a protocol type, and is used to limit the QoS flow to the purpose of sending and receiving UAS control messages. That is, the destination IP address and the destination port are respectively set to the IP address and port of the UTM server specified in the subscriber information received by (or preset in) the SMF. The SMF may set a QFI value specified for the UAS service in the PDU session establishment response message or include a separate indicator such as type=UAS service in the PDU session establishment response message, and send the message to the base station and the terminal to maintain the corresponding PDU session and QoS flow, thereby enabling the sending and receiving of UAS control messages even when the base station and the terminal move outside the specified communication service area.

[0145] When the terminal moves outside the service area relative to the UAS terminal in a situation where the service area of the UAS terminal is defined and managed by referring to the Figure 8 process described, in operation 918, the base station may detect that the terminal has moved outside the service area based on the received service area information, and in operations 919 to 920, the base station may report to the UTM via the AMF that the terminal has moved outside the service area.

[0146] In addition to the above, in operation 921, the UAS terminal may perform an operation of reporting the position of the terminal to the UTM via the UAS control message.

[0147] In operation 922, the UTM may detect that the terminal has moved outside the UAS service allowed area based on the position information of the UAS terminal (the position information is received from the UAS terminal or the wireless communication system), and determine a previously specified command (for example, return to the allowed area, land, etc.) required for controlling the UAS terminal.

[0148] In operation 923, the UTM sends a UAS control message to the wireless communication system, and the wireless communication system delivers the UAS control message to the UAS terminal through a PDU session and a QoS flow maintained for the purpose of UAS transmission. When receiving the UAS control message, the UAS terminal can perform necessary operations according to the commands specified by the UTM.

[0149] According to an embodiment of the present disclosure, the UTM can send information about a no-fly zone of the UAS terminal to the CN of the wireless communication system. The CN can configure UAS service restriction area information (e.g., information about the UAS service area) in the mobile communication system based on the information about the no-fly zone received from the UTM, and deliver the UAS service restriction area information to the RAN.

[0150] According to an embodiment of the present disclosure, the UAS service restriction area information may be a tracking area identifier (TAI) or a cell ID. The UAS service restriction area information is not limited to the above examples, and the UAS service restriction area information may include any type of information capable of identifying the UAS service restriction area.

[0151] That is, the CN can identify which cell or which tracking area the no-fly zone corresponds to, generate (or configure) the UAS service restriction area information as the identified information, and provide the UAS service restriction area information to the RAN.

[0152] According to an embodiment of the present disclosure, in the process of determining whether a handover occurs, based on the channel quality information included in the measurement report received from the terminal, the RAN can perform an operation of selecting a target cell for handover considering the current cell ID of the terminal, the GPS location information, the UAS service restriction area information, etc.

[0153] Figure 10 Illustrates a method for delivering a UAS control message to a UAS terminal by a UTM using a control message of a wireless communication system according to an embodiment of the present disclosure.

[0154] Figure 10 Illustrates a process of sending a UAS control message by using a control plane message of the wireless communication system, i.e., a NAS message, as described above in Figure 7 The case may be a case where a separate PDU session and QoS flow are not previously set for the UAS service described for reference Figure 10 and the NAS message of the wireless communication system is used to deliver the UAS control message from the UTM to the UAS terminal. Figure 9

[0155] Figure 9 ​​As described, in operation 1011, the base station may detect a UAS terminal that has moved outside the UAS service area, and in operations 1012 to 1013, the base station may report the location information of the UAS terminal to the UTM.

[0156] In addition to the above, in operation 1014, the UAS terminal may perform an operation of reporting the location of the terminal to the UTM via a UAS control message.

[0157] In operation 1015, the UTM detects that the UAS terminal has left the service permitted area based on the received information. The UTM may determine the control commands required to control the UAS terminal.

[0158] In operation 1016, the UTM sends a UAS control message to the AF (or NEF) of the wireless communication system to request delivery of the UAS control message (UAS command) to the UAS terminal.

[0159] In operation 1017, the AF and NEF may send a direct delivery request message including the UAS control message to the SMF for sending the received UAS control message. In this case, the AF may send the direct delivery request message by including indicator information therein indicating that the request is for the sending of a UAS control message.

[0160] In operation 1018, the SMF may configure a NAS transfer control message including the UAS control message and send the NAS transfer control message to the UAS terminal by using a port (or a separate indicator) designated for UAS services. The terminal that receives the NAS transfer control message may confirm that the received NAS transfer message is for delivering the UAS control message based on the port (or separate indicator) previously designated for UAS services, which is included in the message. The terminal may extract the UAS control message and deliver it to the UAS application client of the terminal. The terminal may interpret the received UAS control message to perform the operations specified by the UTM.

[0161] Figure 11 Illustrates a method for delivering a UAS control message by the UTM using the emergency session function of a wireless communication system according to an embodiment of the present disclosure.

[0162] Figure 11 Is a diagram illustrating a process of delivering a UAS control message to a UAS terminal that has left the UAS service permitted area by using the emergency session function of the wireless communication system as described above with reference to Figure 8 Description of the wireless communication system's emergency session function.

[0163] As referred to Figure 9 And Figure 10As described, in operations 1111 to 1115, the UTM can determine that the UAS terminal has left the UAS service area based on the location information of the terminal received from the RAN, and can determine the necessary control commands. The above corresponds to the description provided in reference Figure 9 and Figure 10 For the sake of brevity, the detailed description thereof is omitted here.

[0164] In operation 1116, the UTM can send a message requesting an emergency session setup to the wireless communication system to deliver the control command. The message requesting an emergency session setup can include an indicator indicating that the emergency session setup request is for UAS service and UTM information. According to an embodiment of the present disclosure, the UTM information can include at least one of a source IP, a source port, a destination IP, a destination port, and protocol type information to be used for the delivery of UAS messages. The PCF of the wireless communication system can identify the UTM based on the subscriber information of the UAS terminal, determine whether to accept the emergency session request received from the UTM, and can proceed with the processes necessary for emergency session setup when it is determined to allow the emergency session request. The PCF can respond to the completion of the UTM emergency session setup, and the UTM that has received the response can send a UAS control message to the terminal through the PDU session for the set emergency session. When receiving the UAS control message, the UAS terminal can perform necessary operations according to the control commands specified by the UTM.
