After the unmanned aerial device accesses a mobile communication network, a connection can also be established between the unmanned aerial device and the controller of the unmanned aerial device through the mobile communication network, so that the controller of the unmanned aerial device can control the unmanned aerial device.

[0015] For example, as shown in FIG. 1, the first unmanned aerial device and the second unmanned aerial device both establish a connection with the UTM via a 3GPP (3rd Generation Partnership Project) communication network, the unmanned aerial device transmits data between the UTM and the UTM via the 3GPP communication network, and the first controller of the first unmanned aerial device also transmits data with the UTM via the 3GPP communication network to control the first unmanned aerial device based on the 3GPP communication network, and the second controller of the second unmanned aerial device directly controls the second unmanned aerial device, and does not need to control the second unmanned aerial device based on the 3GPP communication network.

[0016] In some embodiments, the 3GPP communication network is a 5G communication network, and the architecture of the 5G network system is as shown in FIG. 2, in which a terminal device makes an access layer connection with an access network through a Uu (a certain communication interface) port, and further transmits access layer messages through the access network, and performs wireless data transmission. And the terminal device makes a non-access layer connection with an AMF (Access and Mobility Management Function) network element through an N1 (a certain communication interface) port, and transmits non-access layer messages with the AMF network element. The UDM (Unified Data Management) is a contract database in the core network, and is used to store contract data of terminal devices in the 5G network. The AMF network element has a mobility management function and a forwarding function for session management messages, and the SMF (Session Management Function) network element has a session management function. The PCF (Policy Control Function) network element has a policy management function, and is responsible for formulating policies regarding mobility management, session management, charging, etc. for terminal devices. The UPF (User Plane Function) network element has a user plane function, performs data transmission with an external data network through the N6 interface, and performs data transmission with the core network through the N3 (a communication interface) interface. After the terminal device accesses the 5G network through the Uu port, it deviceIt establishes a PDU (Protocol Data Unit) session data connection from to UPF and transmits data. NSSF (Network Slice Selection Function) network element is used to select a network slice. AUSF (Authentication Server Function) has authentication function.

[0017] In some embodiments, the access network includes several base stations. A base station is a device installed in an access network to provide wireless communication functions to terminal devices. The base station may include various types of macro base stations, micro base stations, relay stations, access points, etc. In systems employing different wireless access technologies, the name of a device having the function of a base station may be different, for example, in an LTE system, it is called eNodeB or eNB, and in a 5G NR-U system, it is called gNodeB or gNB. As communication technology develops, the description of "base station" may change.

[0018] The terminal device may include various handheld devices, in-vehicle devices, wearable devices, computing devices or other processing devices connected to a wireless modem having wireless communication capabilities, as well as various forms of user devices, mobile stations (MS), unmanned aerial vehicles, etc. For convenience of explanation, the above devices are collectively referred to as terminal devices.

[0019] FIG. 3 shows a flowchart of a method for obtaining target information according to an exemplary embodiment of the present invention, which is applied to a network device and a terminal device, and includes at least part of the following contents:

[0020] In step (301), the network device transmits an information acquisition request to the terminal device. In an embodiment of the present invention, when a terminal device is connected to a management device of the terminal device via a network device, in order to determine whether the terminal device is an authorized device, the network device needs to determine the result of authorization or authentication between the terminal device and the management device, and provides services and control functions to the terminal device if it determines that the terminal device is an authorized device.

[0021] When the network device determines that authentication or authorization is required for the terminal device, it sends an information acquisition request to the terminal device and instructs the terminal device to send target information to the network device based on the information acquisition request.

[0022] It should be noted that the embodiment of the present invention only takes the network device sending an information acquisition request to the terminal device as an example for description, in other embodiments, the network device needs to determine whether to send an information acquisition request to the terminal device according to the request sent by the terminal device.

[0023] In some embodiments, the network device sends an information acquisition request to the terminal device in response to a registration request sent by the terminal device.

[0024] First type: Each time the network device receives a registration request sent by the terminal device, the network device sends an information acquisition request to the terminal device.

[0025] The terminal device transmits a registration request to the network device to request registration, and when the network device receives the registration request, the network device can determine that authentication or authorization needs to be performed on the terminal device. Each time the network device receives a registration request transmitted by the terminal device, the network device transmits an information acquisition request to the terminal device. Here, the registration request is used to instruct the terminal device to register with the network device.

[0026] In an embodiment of the present invention, each time a network device receives a registration request sent by a terminal device, it obtains target information of the terminal device, ensuring that it can authenticate or authorize the terminal device every time, thereby improving the security of communication with the terminal device.

[0027] Second type: When the network device receives a registration request sent by the terminal device for the first time, the network device sends an information acquisition request to the terminal device.

[0028] In an embodiment of the present invention, the terminal device sends a registration request to the network device multiple times, and when the network device receives the registration request sent by the terminal device for the first time, it sends an information acquisition request to the terminal device, and then, when the terminal device sends the registration request again, it needs to send the information acquisition request to the terminal device again to obtain the target information of the terminal device.

[0029] In an embodiment of the present invention, when a network device receives a registration request sent by a terminal device for the first time, it obtains target information of the terminal device by sending an information acquisition request, and then authorizes or authenticates the terminal device. When a network device receives a registration request for the terminal device again, there is no need to authorize or authenticate the terminal device again, so there is no need to obtain the target information of the terminal device again, which saves signaling overhead and improves resource utilization.

[0030] For example, as shown in FIG. 4, before step (301), the method further includes step (401).

[0031] In step (401), the terminal device sends a registration request to the network device. After the terminal device sends a registration request to the network device, if the network device determines that authentication or authorization needs to be performed on the terminal device, the network device executes step (301).

[0032] Note that the embodiments of the present invention only describe a network device as an example, and in other embodiments, the network device is an AMF network element, the terminal device registers with the AMF network element, and the AMF network element sends an information acquisition request to the terminal device.

[0033] In some embodiments, the network device sends a get information request to the terminal device in response to a session establishment request or a session modification request sent by the terminal device.

[0034] First type: the network device sends an information acquisition request to the terminal device every time it receives a session establishment request or a session modification request sent by the terminal device.

[0035] Here, the session establishment request is used to instruct the terminal device to request the network device to establish a PDU session corresponding to the target condition, and the session modification request is used to instruct the terminal device to request the network device to modify the PDU session corresponding to the target condition. Here, the PDU session corresponding to the target condition corresponds to a pre-configured DNN. PDU A session, or a PDU session corresponding to a pre-configured network slice identifier.

[0036] In an embodiment of the present invention, in order to request a network device to establish a PDU session that corresponds to a target condition or to modify a PDU session that corresponds to a target condition, the terminal device sends a session establishment request or a session modification request to the network device, and upon receiving the session establishment request or session modification request, the network device can determine that authentication or authorization is required for the terminal device, thereby sending an information acquisition request to the terminal device each time the network device receives a session establishment request or a session modification request sent by the terminal device.

[0037] In an embodiment of the present invention, each time a network device receives a session establishment request or a session modification request sent by a terminal device, the network device obtains target information of the terminal device, ensuring that authentication or authorization can be performed for the terminal device every time, thereby improving the security of communication with the terminal device.

[0038] Second type: When the network device first receives a session establishment request or a session modification request sent by the terminal device, the network device sends an information acquisition request to the terminal device.

[0039] In an embodiment of the present invention, a terminal device sends a session establishment request or a session modification request to a network device multiple times, and when the network device receives a session establishment request or a session modification request sent by the terminal device for the first time, the network device sends an information acquisition request to the terminal device, and then, when the terminal device sends a session establishment request or a session modification request again, the network device needs to send an information acquisition request to the terminal device again to obtain target information of the terminal device.

[0040] In an embodiment of the present invention, when a network device receives a session establishment request or a session modification request sent by a terminal device for the first time, it obtains target information of the terminal device by sending an information acquisition request, and then authorizes or authenticates the terminal device. When a network device receives a session establishment request or a session modification request from the terminal device again, it does not need to authorize or authenticate the terminal device again, so it does not need to obtain the target information of the terminal device again, which saves signaling overhead and improves resource utilization.

[0041] For example, as shown in FIG. 5, before step (301), the method further includes step (501).

[0042] In step (501), the terminal device sends a session establishment request or a session modification request to the network device. After the terminal device sends a session establishment request or a session modification request to the network device, if the network device can determine that authorization needs to be performed for the terminal device based on the session establishment request or the session modification request, the network device executes step (301).

[0043] It should be noted that the embodiment of the present invention only takes the network device to perform step (301) as an example for description. In another embodiment, the network device is an SMF network element, and the terminal device requests the SMF network element to establish or modify a PDU session corresponding to a target condition, and the SMF network element sends an information acquisition request to the terminal device.

[0044] In one possible implementation manner, the mutual information between the SMF network element and the terminal device needs to be transparently transmitted through the AMF network element, that is, the AMF network element has a forwarding function, and the mutual information between the SMF network element and the terminal device needs to be forwarded through the AMF network element.

[0045] In the embodiment of the present invention, the network device determines to send an information acquisition request to the terminal device in response to a session establishment request or a session modification request sent by the terminal device. In another embodiment, when the network device receives a session establishment request or a session modification request sent by the terminal device, it first determines whether or not it has obtained an authentication result or an authorization result for the terminal device, and if the network device has obtained an authorization result or an authentication result for the terminal device, it does not send an information acquisition request to the terminal device and performs authorization or authentication for the terminal device. On the other hand, if the network device does not obtain an authentication result or an authorization result for the terminal device, it sends an information acquisition request to the terminal device.

[0046] In some embodiments, the network device is an SMF network element, and the SMF network element determines whether to obtain an authorization result or authentication result from the AMF network element, and further determines whether to send an information acquisition request to the terminal device, where the AMF network element determines to send an information acquisition request to the terminal device according to a registration request sent by the terminal device, and performs authentication or authorization for the terminal device according to the obtained target information of the terminal device, and obtains an authorization result or authentication result for the terminal device.

[0047] In some further embodiments, the network device sends an information acquisition request to the terminal device when a pre-defined time point is reached.

[0048] In the network device, a preset time point is set, and when the preset time point is reached, approval or authentication is required for the terminal device, and thus an information acquisition request is sent to the terminal device to obtain the target information of the terminal device.

[0049] Here, the pre-set time point is set by the network device, or set by an operator, or set in other manners.

[0050] The network device can set one or more preset time points, and sends an information acquisition request to the terminal device each time the preset time point is reached.

[0051] In step (302), the terminal device receives an information acquisition request sent by the network device.

[0052] In step (303), the terminal device transmits the target information to the network device according to the information acquisition request.

[0053] In an embodiment of the present invention, when a network device sends an information acquisition request to a terminal device, the terminal device can receive the information acquisition request sent by the network device and determine that the network device needs to acquire the target information of the terminal device, thus device transmits the target information to the network device based on the information acquisition request.

[0054] Here, the target information is used by the management device to perform authentication or authorization for the terminal device.

[0055] In some embodiments, the target information includes at least one of an identifier of the terminal device, a serial number of the terminal device, pilot information of the terminal device, manufacturer information of the terminal device, or a device type of the terminal device.

[0056] Here, the target information can indicate any terminal device. The identifier of the terminal device is the ID (Identity document, identification number) of the terminal device or other identifiers. The serial number of the terminal device is a number added to the terminal device by the manufacturer during the manufacturing process. For example, the serial number of the terminal device may be added in the order of manufacture of the terminal device or added in other ways. The pilot information of the terminal device is an identifier of a user who logs in to the terminal device. The manufacturer information of the terminal device is information of the manufacturer that manufactures the terminal device, and the manufacturer to which the terminal device belongs can be determined according to the manufacturer information. The device type of the terminal device is the type to which the terminal device belongs.

[0057] In some embodiments, the terminal device is an unmanned aerial vehicle device, and thus the device type is a type to which the unmanned aerial vehicle device belongs, for example, the device types include fixed-wing unmanned aerial vehicles, rotary-wing unmanned aerial vehicles, umbrella-wing unmanned aerial vehicles, etc.

[0058] In step (304), the network device receives the target information sent by the terminal device.

[0059] In step (305), the network device transmits the target information to the management device of the terminal device.

[0060] In an embodiment of the present invention, when the network device transmits the received target information to the management device, the management device can perform authentication or authorization for the terminal device according to the target information.

[0061] Wherein, the management device is a UTM, a USS or other device having management function, wherein the UTM or the USS can perform authorization or authentication on the terminal device and determine the authorization result or authentication result on the terminal device.

[0062] In some embodiments, the network device sends an authorization request carrying the target information to the terminal device, or the network device sends an authentication request carrying the target information to the terminal device.

[0063] In the embodiment of the present invention, the network device only transmits an information acquisition request to the terminal device once. In other embodiments, after the network device transmits the information acquisition request to the terminal device, the network device transmits the information acquisition request to the terminal device again for each reference time length, and continues to execute steps (302) to (305).

[0064] Here, the reference time length is set by the network device, or by an operator, or set in other manners, for example, the reference time length is 10 seconds, 20 seconds, or other value.

[0065] In an embodiment of the present invention, after receiving the target information of the terminal device, the management device can perform authorization or authentication on the terminal device based on the target information, and determine an authorization result or authentication result.

[0066] After the management device determines the approval result or authentication result, it transmits the approval result or authentication result to the network device, and the network device transmits the approval result or authentication result to the terminal device.

[0067] Note that the embodiments of the present invention are only described by taking as an example the network device being an AMF network element or an SMF network element, and in other embodiments, the network device further includes an unmanned aerial vehicle management function network element, and the AMF network element or SMF network element sends target information to the unmanned aerial vehicle management function network element, and the unmanned aerial vehicle management function network element sends the target information to the management device.
