[0045] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0046] It can be understood that the terms "first", "second", etc. used in this application can be used to describe various concepts in this article, but unless otherwise specified, these concepts are not limited by these terms. These terms are only used to distinguish one concept from another concept.

[0047] The embodiments of the present application are applied in the scenario where the drone device communicates with UTM (Unmanned Aerial System Traffic Management) or USS (UAS Service Supplier) through a mobile communication network. The drone device can access the mobile communication network and establish a connection with the UTM or USS. The UTM or USS is responsible for registering, tracking the location or controlling the drone device. In addition, after the drone device accesses the mobile communication network, it can also establish a connection with the controller of the drone device through the mobile communication network, so that the controller of the drone device can control the drone device.

[0048] For example, Figure 1As shown, both the first drone device and the second drone device establish a connection with the UTM via the 3GPP (3rd Generation Partnership Project) communication network, so that the drone device transmits data with the UTM via the 3GPP communication network, and the first controller of the first drone device can also transmit data with the UTM via the 3GPP communication network, and the first drone device is controlled based on the 3GPP communication network, and the second controller of the second drone device directly controls the second drone device, without the need to control the second drone device based on the 3GPP communication network.

[0049] In some embodiments, the 3GPP communication network is a 5G communication network, and the 5G network system architecture is as follows: Figure 2 As shown, the terminal device is connected to the access network at the access layer through the Uu (a communication interface) port, and then transmits access layer messages and wireless data transmission through the access network. And the terminal device is connected to the AMF (Access and Mobility Management Function) network element at the non-access layer through the N1 (a communication interface) port, and transmits non-access layer messages with the AMF network element. UDM (Unified Data Management) is a contract database in the core network, which is used to store the contract data of the terminal device in the 5G network. The AMF network element has the mobility management function and the forwarding function of the session management message, and the SMF (Session Management Function) network element has the session management function. The PCF (Policy Control Function) network element has the policy management function, which is responsible for formulating the mobility management, session management, billing and other related policies for the terminal device. The UPF (UserPlane Function) network element has the user plane function, and transmits data with the external data network through the N6 interface, and transmits data with the core network through the N3 (a communication interface) interface. After the terminal device accesses the 5G network through the Uu port, a PDU (Protocol Data Unit) session data connection is established from the terminal to the UPF under the control of the SMF for data transmission. The NSSF (Network Slice Selection Function) network element is used to select network slices. The AUSF (Authentication Server Function) has an authentication function.

[0050] In some embodiments, the access network includes several base stations. A base station is a device deployed in the access network to provide wireless communication functions for terminal devices. Base stations may include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems using different wireless access technologies, the names of devices with base station functions may be different. For example, in LTE systems, they are called eNodeB or eNB; in 5G NR-U systems, they are called gNodeB or gNB. As communication technology evolves, the description of "base station" may change.

[0051] Terminal devices may include various handheld devices with wireless communication functions, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to wireless modems, as well as various forms of user equipment, mobile stations (MS), drone devices, etc. For the convenience of description, the above-mentioned devices are collectively referred to as terminal devices.

[0052] Figure 3 A flowchart of a method for acquiring target information provided by an exemplary embodiment of the present application is shown, which is applied to a network device and a terminal device. The method includes at least part of the following contents:

[0053] 301. The network device sends an information acquisition request to the terminal device.

[0054] In an embodiment of the present application, when a terminal device is connected to a management device of the terminal device through a network device, the network device needs to determine the authorization or authentication result of the terminal device and the management device to determine whether the terminal device is a legal device, and provide services and control functions to the terminal device when it is determined that the terminal device is legal.

[0055] If the network device determines that the terminal device needs to be authenticated or authorized, it sends an information acquisition request to the terminal device to instruct the terminal device to send target information to the network device based on the information acquisition request.

[0056] It should be noted that the embodiment of the present application is only described by taking the example of a network device sending an information acquisition request to a terminal device. In another embodiment, 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.

[0057] In some embodiments, the network device sends an information acquisition request to the terminal device according to the registration request sent by the terminal device:

[0058] The first type: each time the network device receives a registration request sent by the terminal device, it sends an information acquisition request to the terminal device.

[0059] The terminal device will send a registration request to the network device to request registration. After receiving the registration request, the network device can determine that the terminal device needs to be authenticated or authorized. Each time the network device receives a registration request sent by the terminal device, it sends an information acquisition request to the terminal device. The registration request is used to instruct the terminal device to register with the network device.

[0060] The network device in the embodiment of the present application obtains the target information of the terminal device each time it receives a registration request sent by the terminal device, ensuring that the terminal device can be authenticated or authorized each time, thereby improving the security of communication with the terminal device.

[0061] The second type: after 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.

[0062] In an embodiment of the present application, the terminal device will send registration requests to the network device multiple times, and after the network device receives the registration request sent by the terminal device for the first time, it will send an information acquisition request to the terminal device. When the terminal device sends a registration request again subsequently, it is necessary to send an information acquisition request to the terminal device again to obtain the target information of the terminal device.

[0063] After the network device in the embodiment of the present application receives the registration request sent by the terminal device for the first time, it obtains the target information of the terminal device by sending an information acquisition request, and subsequently authorizes or authenticates the terminal device. If the network device receives the registration request from the terminal device again, there is no need to authorize or authenticate the terminal device again. Therefore, there is no need to obtain the target information of the terminal device again, which saves signaling overhead and improves resource utilization.

[0064] For example, Figure 4 As shown, before step 301, the method further includes step 401:

[0065] 401. The terminal device sends a registration request to the network device.

[0066] After the terminal device sends a registration request to the network device, if the network device determines that the terminal device needs to be authenticated or authorized, the network device executes step 301.

[0067] It should be noted that the embodiment of the present application is only described by taking a network device as an example. In another embodiment, 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.

[0068] In some other embodiments, the network device sends an information acquisition request to the terminal device according to the session establishment request or session modification request sent by the terminal device:

[0069] The first type: each time the network device receives a session establishment request or a session modification request sent by the terminal device, it sends an information acquisition request to the terminal device.

[0070] The session establishment request is used to instruct the terminal device to request the network device to establish a PDU session that meets the target conditions, and the session modification request is used to instruct the terminal device to request the network device to modify the PDU session that meets the target conditions. The PDU session that meets the target conditions is a session corresponding to a preset DNN, or a PDU session corresponding to a preset network slice identifier.

[0071] In an embodiment of the present application, the terminal device will send a session establishment request or a session modification request to the network device to request the network device to establish a PDU session that meets the target conditions or modify the PDU session that meets the target conditions. After the network device receives the session establishment request or the session modification request, it can determine that the terminal device needs to be authenticated or authorized. Therefore, each time the network device receives a session establishment request or a session modification request sent by the terminal device, it sends an information acquisition request to the terminal device.

[0072] The network device in the embodiment of the present application obtains the target information of the terminal device each time it receives a session establishment request or a session modification request sent by the terminal device, ensuring that the terminal device can be authenticated or authorized each time, thereby improving the security of communication with the terminal device.

[0073] The second type: after the network device receives the session establishment request or session modification request sent by the terminal device for the first time, it sends an information acquisition request to the terminal device.

[0074] In an embodiment of the present application, the terminal device may send a session establishment request or a session modification request to the network device multiple times, and the network device may send an information acquisition request to the terminal device after receiving the session establishment request or the session modification request sent by the terminal device for the first time. When the terminal device subsequently sends a session establishment request or a session modification request again, it is necessary to send an information acquisition request to the terminal device again to obtain the target information of the terminal device.

[0075] After the network device in the embodiment of the present application receives a session establishment request or a session modification request sent by the terminal device for the first time, it obtains the target information of the terminal device by sending an information acquisition request, and subsequently authorizes or authenticates the terminal device. If the network device receives a session establishment request or a session modification request from the terminal device again, there is no need to authorize or authenticate the terminal device again. Therefore, there is no need to obtain the target information of the terminal device again, which saves signaling overhead and improves resource utilization.

[0076] For example, Figure 5 As shown, before step 301, the method further includes step 501:

[0077] 501. The terminal device sends a session establishment request or a session modification request to the network device.

[0078] After the terminal device sends a session establishment request or a session modification request to the network device, the network device can determine that the terminal device needs to be authorized based on the session establishment request or the session modification request, and then the network device executes step 301.

[0079] It should be noted that the embodiment of the present application is only described by taking the network device executing step 301 as an example. 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 that meets the target conditions, and the SMF network element sends an information acquisition request to the terminal device.

[0080] In one possible implementation, the interactive 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 interactive information between the SMF network element and the terminal device needs to be forwarded through the AMF network element.

[0081] It should be noted that the embodiment of the present application is only described by taking the example that the network device determines to send an information acquisition request to the terminal device according to the session establishment request or session modification request sent by the terminal device. In another embodiment, the network device receives the session establishment request or session modification request sent by the terminal device, and first determines whether the authentication result or authorization result of the terminal device has been obtained. If the network device has obtained the authorization result or authentication result of the terminal device, it does not send an information acquisition request to the terminal device to authorize or authenticate the terminal device. If the network device has not obtained the authentication result or authorization result of the terminal device, it sends an information acquisition request to the terminal device.

[0082] In some embodiments, the network device is an SMF network element, and the SMF network element determines whether to obtain an authorization result or an authentication result from an AMF network element, and then determines whether to send an information acquisition request to the terminal device. The AMF network element determines to send an information acquisition request to the terminal device according to the registration request sent by the terminal device, so as to authenticate or authorize the terminal device according to the target information of the terminal device obtained, and obtain the authorization result or authentication result of the terminal device.

[0083] In other embodiments, the network device sends an information acquisition request to the terminal device when a preset time point is reached.

[0084] A preset time point is set in the network device. When the preset time point is reached, the terminal device needs to be authorized or authenticated, and an information acquisition request is sent to the terminal device to obtain the target information of the terminal device.

[0085] The preset time point is set by the network device, or by an operator, or by other methods.

[0086] The network device can set one or more preset time points, and when each preset time point is reached, it sends an information acquisition request to the terminal device.

[0087] 302. The terminal device receives an information acquisition request sent by the network device.

[0088] 303. The terminal device sends target information to the network device based on the information acquisition request.

[0089] In an embodiment of the present application, if 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 obtain the target information of the terminal device. Then, based on the information acquisition request, the terminal sends the target information to the network device.

[0090] The target information is used by the management device to authenticate or authorize the terminal device.

[0091] In some embodiments, the target information includes at least one of an identification 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.

[0092] Among them, the target information can indicate a terminal device. The identification of the terminal device is the ID (Identity document) of the terminal device, or other identification. The serial number of the terminal device is the number marked by the manufacturer during the production process of the terminal device. For example, the serial number of the terminal device is marked according to the production order of the terminal device, or is marked in other ways. The pilot information of the terminal device is the user identification for logging into the terminal device. The manufacturer information of the terminal device is the manufacturer information of the terminal device, and the manufacturer to which the terminal device belongs can be determined based on the manufacturer information. The device type of the terminal device is the type to which the terminal device belongs.

[0093] In some embodiments, the terminal device is a drone device, and the device type is the type of the drone device. For example, the device type includes a fixed-wing drone, a rotary-wing drone, a paraglider drone, and the like.

[0094] 304. The network device receives the target information sent by the terminal device.

[0095] 305. The network device sends target information to the management device of the terminal device.

[0096] In an embodiment of the present application, the network device sends the received target information to the management device, and the management device can authenticate or authorize the terminal device based on the target information.

[0097] The management device is a UTM, a USS or other devices with management functions, wherein the UTM or the USS can authorize or authenticate the terminal device to determine the authorization result or the authentication result of the terminal device.

[0098] In some embodiments, the network device sends an authorization request carrying target information to the terminal device, or the network device sends an authentication request carrying target information to the terminal device.

[0099] It should be noted that the embodiment of the present application is only described by taking the network device sending an information acquisition request to the terminal device as an example. In another embodiment, after the network device sends the information acquisition request to the terminal device, it sends the information acquisition request to the terminal device again at a reference time length, and continues to execute steps 302-305.

[0100] The reference duration is set by the network device, or by an operator, or by other methods. For example, the reference duration is 10 seconds, 20 seconds, or other values.

[0101] In an embodiment of the present application, after the management device receives the target information of the terminal device, it can authorize or authenticate the terminal device based on the target information and determine the authorization result or the authentication result.

[0102] After the management device determines the authorization result or the authentication result, it sends the authorization result or the authentication result to the network device, and the network device then sends the authorization result or the authentication result to the terminal device.

[0103] It should be noted that the embodiments of the present application are only described using the network device as an AMF network element or an SMF network element as an example. In another embodiment, the network device also includes a drone management function network element. The AMF network element or the SMF network element sends target information to the drone management function network element, and the drone management function network element then sends the target information to the management device.

[0104] An embodiment of the present application provides a solution for obtaining target information for authentication or authorization. On the premise that a network device sends an information acquisition request to a terminal device, the terminal device sends the target information for authentication or authorization, thereby preventing the terminal device from repeatedly sending the target information due to actively sending the target information, reducing resource waste and improving resource utilization.

[0105] In some embodiments, the terminal device is a drone device, the network device is an AMF network element, and the management device of the drone device is a UTM, and the UTM is connected to the drone management function network element.
