Detailed Implementation

[0020] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0021] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0022] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0023] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0024] Smart agriculture, as an important development direction of modern agriculture, is gradually adopting unmanned agricultural machinery service systems to improve the level of automation. Unmanned agricultural machinery can typically perform tasks such as sowing, fertilizing, and harvesting, which can improve production efficiency and reduce reliance on human labor.

[0025] An unmanned agricultural machinery system typically includes an unmanned agricultural machinery terminal, a communication network, and a management platform. The unmanned agricultural machinery terminal can send operating data, receive control commands, and execute corresponding tasks. The management platform is used to monitor and schedule the unmanned agricultural machinery. Data transmission occurs between the unmanned agricultural machinery terminal and the management platform via the communication network.

[0026] See Figure 1 This is a schematic diagram of a network architecture for an application scenario provided in an embodiment of this application, such as... Figure 1 As shown, the unmanned agricultural machinery terminal 110 includes a first unmanned agricultural machinery 111, a second unmanned agricultural machinery 112, and a third unmanned agricultural machinery 113. The communication network 120 includes an access network 121, a bearer network 122, and a core network 123 connected in sequence. Each of the unmanned agricultural machinery 111-113 in the unmanned agricultural machinery terminal 110 establishes a communication link with the base station 1211 in the access network 121, and the core network 123 is connected to the management platform 130.

[0027] The unmanned agricultural machinery 111-113 in the unmanned agricultural machinery terminal 110 can acquire and transmit their own operating condition data, i.e., the operating condition data of the unmanned agricultural machinery terminal, and simultaneously receive and execute control commands from the management platform 130. Specifically, the unmanned agricultural machinery terminal sends its operating condition data to the base station 1211 in the access network 121 via a wireless communication link; the access network receives the data and transmits it to the core network 123 through the bearer network 122, and finally to the management platform 130. The control commands generated by the management platform 130 are first sent to the core network 123, then forwarded to the access network 121 through the bearer network 122, and finally distributed by the access network 121 to the unmanned agricultural machinery terminal 110 or one or more corresponding unmanned agricultural machinery in the unmanned agricultural machinery terminal 110 through the base station 1211.

[0028] Understandably, the management platform 130 can determine control commands based on the working condition data of the unmanned agricultural machinery terminal, and realize, but not limited to, status monitoring, path planning, task scheduling and management of multiple unmanned agricultural machinery terminals 110, such as querying the work task status of the first unmanned agricultural machinery 111, starting the second unmanned agricultural machinery 112 and setting the work task and path planning, controlling the third unmanned agricultural machinery 113 to return and shut down at a time, etc.

[0029] It should be pointed out that, such as Figure 1The application scenario shown is only an exemplary application scenario. For example, the number of unmanned agricultural machines in the unmanned agricultural machinery terminal can be more or less, the number of base stations in the access network can be two or more, and the communication links between the unmanned agricultural machinery terminal and the access network can be more. Those skilled in the art can also apply the embodiments of this application to other applicable application scenarios according to actual needs.

[0030] In practical applications, unmanned agricultural machinery systems can also include drone terminals, which can be used to perform tasks such as patrolling, crop monitoring and identification, and high-precision map building. Similarly, the drone terminals can transmit data obtained from these tasks to a management platform via a communication network. The management platform then formulates instructions based on the drone's and the drone terminal's operational data and transmits them to the unmanned agricultural machinery. After receiving the instructions, the drone terminal can typically perform tasks such as sowing, fertilizing, and harvesting.

[0031] It should be noted that the operational data of unmanned agricultural machinery terminals typically includes multiple business flow types, including but not limited to the terminal's status data and environmental data. The terminal's status data may include its location, operational status, and / or equipment information; its environmental data includes, but is not limited to, images of the surrounding environment. The operational data can be acquired through sensors mounted on the unmanned agricultural machinery terminal, including but not limited to cameras, navigation and positioning devices, and status monitoring sensors.

[0032] However, during data transmission in a communication network, factors such as limited network bandwidth may lead to a decline in communication service quality, data transmission delays or losses, thereby increasing the risk of security incidents.

[0033] In view of this, this application provides a communication method for an unmanned agricultural machinery service system based on a 5G / 6G network, which helps to solve the problems of declining communication service quality, data transmission delay or loss, and thus increased risk of safety accidents.

[0034] See Figure 2 This is a flowchart illustrating a communication method for an unmanned agricultural machinery service system provided in an embodiment of this application, which can be applied to, for example... Figure 1 The application scenarios shown include an unmanned agricultural machinery service system comprising an access network, a bearer network, and a core network, such as... Figure 2 As shown, the method specifically includes: S201: The unmanned agricultural machinery terminal sends its operating status data to the access network.

[0035] In practical applications, unmanned agricultural machinery terminals access communication networks via access networks. These access networks are typically used to establish communication links with devices within their coverage area and can also convert between wireless and wired signals. An unmanned agricultural machinery terminal can be a single machine, a swarm of all machines in a scenario, or even a subset of machines within a swarm. The operational data of the unmanned agricultural machinery terminal typically includes its status data and environmental data. The status data can be the location, operating status, and / or equipment information of each or at least one machine, while the environmental data can be images of the surrounding environment collected by at least one or each machine. The methods for acquiring the operational data of the unmanned agricultural machinery terminal are similar to those used in application scenarios and will not be elaborated upon here.

[0036] Furthermore, the unmanned agricultural machinery terminal communicates with the access network. For example, the unmanned agricultural machinery terminal can access the access network by establishing a communication link with a 5G base station or a 6G base station in the access network, thus realizing the communication connection between the unmanned agricultural machinery terminal and the access network. In this way, the unmanned agricultural machinery terminal can send its operating status data to the access network and / or receive data sent by the access network.

[0037] Of course, those skilled in the art can also choose other methods for acquiring, transmitting, and specifying the content of unmanned agricultural machinery terminal operating data according to actual needs. This application does not impose specific limitations in this regard.

[0038] In one possible implementation, the access network includes at least one base station, and the unmanned agricultural machinery terminal sends its operating status data to at least one base station in the access network.

[0039] Understandably, in agricultural settings, there may be weak signal areas or even blind spots at the edges of base station signals. When unmanned agricultural machinery (UAVs) enter these areas, they may be unable to establish a communication link with base stations in the access network, leading to network connection interruptions, poor signal quality, data loss, and even increased risk of accidents.

[0040] In practical applications, an access network typically includes two or more base stations. An unmanned agricultural machinery terminal can access the access network and send data to it by establishing a communication link with one base station; it can also access the access network and send data by establishing multiple communication links with two or more base stations.

[0041] Of course, those skilled in the art can also achieve zero-interruption handover when establishing communication links with different base stations through technologies such as Dual Active Protocol Stack (DAPS) and Packet Data Convergence Protocol (PDCP) packet duplication technology, thereby further improving connection status and signal quality.

[0042] It should be noted that the unmanned agricultural machinery terminal can also communicate with the access network through the identity authentication module. The identity authentication module is usually used to generate communication keys to prevent counterfeit devices from accessing the communication network, avoid eavesdropping or tampering with the unmanned agricultural machinery terminal's operating data, and prevent network attacks.

[0043] In one possible implementation, the unmanned agricultural machinery terminal determines its communication key through an authentication module and sends the communication key to the access network. The access network receives the communication key sent by the unmanned agricultural machinery terminal and determines whether the unmanned agricultural machinery terminal is an authorized access device based on the communication key. If the unmanned agricultural machinery terminal is an authorized access device, the access network establishes a communication link with the unmanned agricultural machinery terminal. In this way, the unmanned agricultural machinery terminal can communicate with the management platform through the communication network.

[0044] Of course, those skilled in the art can also choose other methods to prevent unauthorized terminal access, such as dynamically generating a unique session key for each unmanned agricultural machine through a Generic Bootstrapping Architecture (GBA) two-way authentication mechanism to establish a security system. This application does not impose specific limitations on this approach.

[0045] S202: The access network sends the operating status data of the unmanned agricultural machinery terminal to the bearer network.

[0046] In this embodiment of the application, the access network receives the operating status data of the unmanned agricultural machinery terminal sent by the unmanned agricultural machinery terminal, and sends the operating status data of the unmanned agricultural machinery terminal to the bearer network.

[0047] In practical applications, the access network can also manage transmitted data. For example, the access network can convert the unmanned agricultural machinery terminal operating status data sent by the unmanned agricultural machinery terminal from wireless signals to wired signals, so that it can be transmitted in a wired network.

[0048] The bearer network typically refers to the backbone transmission network connecting the access network and the core network. It is usually composed of optical fibers, routers, and switches. It is typically used as a data channel to transmit data and usually does not parse or process the transmitted data content.

[0049] Furthermore, the access network and the bearer network are connected in communication. For example, the base station equipment in the access network is typically connected to the router or switch in the bearer network via wired transmission media such as optical fiber. In this way, when the access network receives the unmanned agricultural machinery terminal's operating status data from the base station it covers, it can encapsulate and convert the operating status data, and then send the unmanned agricultural machinery terminal's operating status data to the bearer network through its communication interface with the bearer network.

[0050] In one possible implementation, the access network includes at least one base station, which receives the operating status data of the unmanned agricultural machinery terminal sent by the unmanned agricultural machinery terminal and sends the operating status data of the unmanned agricultural machinery terminal to the bearer network. It is understandable that at least one base station in the access network can send the operating status data of the unmanned agricultural machinery terminal to the bearer network through its respective communication interface with the bearer network.

[0051] S203: The bearer network sends the operating status data of the unmanned agricultural machinery terminal to the core network through the unmanned agricultural machinery private network channel in the bearer network.

[0052] In this embodiment of the application, the bearer network receives the operating status data of the unmanned agricultural machinery terminal sent by the access network, and sends the operating status data of the unmanned agricultural machinery terminal to the core network through the unmanned agricultural machinery private network channel in the bearer network.

[0053] In practical applications, the core network typically refers to the control and management center of the communication network. It is usually used for authenticating access users, managing communication sessions, and routing transmitted data to the corresponding target application platform. It is typically composed of a core network server and a core network management system. Furthermore, the bearer network communicates with the core network. For example, the bearer network and the core network are connected through a standard communication interface. The bearer network can send data to the core network through the standard communication interface, such as sending received operating status data from unmanned agricultural machinery terminals.

[0054] Furthermore, a dedicated network channel for unmanned agricultural machinery is deployed within the bearer network. This dedicated network channel refers to a data channel between the access network and the core network specifically used for transmitting data related to unmanned agricultural machinery terminals. In practical applications, this dedicated network channel is typically an isolated channel established within the bearer network. Specifically, it can be a virtual private network channel constructed based on network slicing technology. Of course, those skilled in the art can also choose other methods to determine the dedicated network channel based on actual conditions, such as allocating a dedicated bandwidth path as the dedicated network channel through traffic engineering strategies.

[0055] In practical applications, those skilled in the art can determine the specific configuration of the dedicated network channel for unmanned agricultural machinery based on network resources and business requirements. This specific configuration includes, but is not limited to, the bandwidth, path priority, or quality of service parameters of the dedicated network channel. For example, based on network resources and business requirements, a dedicated network channel for unmanned agricultural machinery can be configured with a wide-area uplink edge speed of 20Mbps and a packet latency of less than or equal to 50 milliseconds for 99% of data packets, i.e., a one-way latency of 50ms@99% performance. Of course, the above configuration of the dedicated network channel for unmanned agricultural machinery is only an exemplary configuration. Those skilled in the art can determine other specific configurations of the dedicated network channel for unmanned agricultural machinery based on network resources and business requirements. For example, by using a 6G network, a higher-speed, lower-latency dedicated network channel for unmanned aerial vehicles can be determined.

[0056] In this way, when the bearer network receives the operating status data of the unmanned agricultural machinery terminal from the access network, it can send the operating status data of the unmanned agricultural machinery terminal to the core network through the unmanned agricultural machinery private network channel in the bearer network.

[0057] In one possible implementation, the bearer network receives the operating status data of the unmanned agricultural machinery terminal sent by the access network, and sends the operating status data of the unmanned agricultural machinery terminal to the core network through at least one service flow channel.

[0058] Among them, the business flow channel matches the business flow type corresponding to the working condition data of the unmanned agricultural machinery terminal, and at least one business flow channel is deployed in the unmanned agricultural machinery private network channel.

[0059] In practical applications, the operational data of unmanned agricultural machinery terminals can typically be divided into at least one service flow type based on the data content and transmission requirements. For example, the operational status data of unmanned agricultural machinery terminals can be classified as operational data of the first service flow type, and the environmental image data of unmanned agricultural machinery terminals can be classified as operational data of the second service flow type.

[0060] Furthermore, within the dedicated network channel for unmanned agricultural machinery, at least one sub-dedicated network channel, i.e., a service flow channel, can be determined based on the transmission requirements of different service flow types. The number of service flow channels can be one or more. Specifically, at least one service flow channel can be determined by associating operational data with a quality of service identifier, and the service quality identifier can be used to determine the priority, latency, packet loss rate, and other configuration parameters of the service flow channel.

[0061] It is understandable that the service flow channel matches the service flow type corresponding to the operating condition data of the unmanned agricultural machinery terminal. For example, within the dedicated network channel for unmanned agricultural machinery, a first service flow channel is determined based on the transmission requirements of the first service flow type, and a second service flow channel is determined based on the transmission requirements of the second service flow type. In this way, the bearer network receives the operating condition data of the first service flow type and the second service flow type sent by the access network, and sends the operating condition data of the first service flow type to the core network through the first service flow channel, and sends the operating condition data of the second service flow type to the core network through the second service flow channel.

[0062] S204: The core network sends control commands to the bearer network. These control commands instruct the unmanned agricultural machinery terminals to perform corresponding services.

[0063] As described in S203 above, the bearer network and the core network are connected in communication, and the core network can send control commands to the bearer network.

[0064] In practical applications, control commands can be determined based on the operating status data of the unmanned agricultural machinery terminal, or they can be determined based on preset logic or user operation. Control commands are used to instruct the unmanned agricultural machinery terminal to perform corresponding tasks. For example, a status query command instructs the unmanned agricultural machinery terminal to perform corresponding status data queries and communications; a task command instructs the unmanned agricultural machinery terminal to perform corresponding tasks, such as harvesting in a specific area; and an equipment control command instructs the unmanned agricultural machinery terminal to perform corresponding equipment controls, such as starting and stopping.

[0065] S205: The carrier network sends control commands to the access network through the unmanned agricultural machinery dedicated network channel in the carrier network.

[0066] In this embodiment of the application, the bearer network receives control commands sent by the core network and sends the control commands to the access network through the unmanned agricultural machinery private network channel in the bearer network.

[0067] As described in S202 and S203 above, the access network and the bearer network are communicatively connected, and a dedicated network channel for unmanned agricultural machinery is deployed in the bearer network. This dedicated network channel for unmanned agricultural machinery refers to a data channel between the access network and the core network specifically used for transmitting data related to unmanned agricultural machinery terminals. In this way, the bearer network can also send control commands to the access network through the dedicated network channel for unmanned agricultural machinery within the bearer network.

[0068] In one possible implementation, the bearer network receives control commands sent by the core network and sends control commands to the access network through the command data channel in the bearer network.

[0069] The command data channel is deployed in the dedicated network channel for unmanned agricultural machinery.

[0070] Similarly, within the dedicated network channel for unmanned agricultural machinery, a sub-dedicated network channel, namely the command data channel, can be determined based on the transmission requirements of control commands. It can be understood that sending control commands to the access network through the command data channel in the bearer network can avoid obstruction of control command transmission during network congestion, thus improving network service quality.

[0071] S206: The access network sends control commands to the unmanned agricultural machinery terminal.

[0072] As described in step S201, the unmanned agricultural machinery terminal is communicatively connected to the access network. The unmanned agricultural machinery terminal can send its operating status data to the access network and / or receive data sent by the access network. In this way, the access network can receive control commands sent by the bearer network through the unmanned agricultural machinery dedicated network channel and send control commands to the unmanned agricultural machinery terminal.

[0073] In one possible implementation, the access network includes at least one base station, through which the access network sends control commands to the unmanned agricultural machinery terminal.

[0074] Similarly, the access network can establish a communication link with the unmanned agricultural machinery terminal through one base station in the access network, and send control commands to the unmanned agricultural machinery terminal through one base station; the access network can also establish a communication link with the unmanned agricultural machinery terminal through two or more base stations in the access network, and send control commands to the unmanned agricultural machinery terminal through at least one base station.

[0075] In one possible implementation, the access network is also used to communicate with the user's mobile device, and the access network sends control commands and / or operating status data of the unmanned agricultural machinery terminal to the user's mobile device.

[0076] Similarly, user mobile devices can access the communication network through the access network. For example, a user mobile device can access the access network by establishing a communication link with a 5G or 6G base station in the access network, thus realizing a communication connection between the user mobile device and the access network. In this way, the access network can send control commands and / or operating status data of the unmanned agricultural machinery terminal to the user mobile device, and the user can receive the control commands and / or operating status data of the unmanned agricultural machinery terminal sent by the access network through the user mobile device.

[0077] See Figure 3 This is a flowchart illustrating another communication method for an unmanned agricultural machinery service system provided in an embodiment of this application, as shown below. Figure 3 As shown, in Figure 2 Based on the method shown, after step S203, the following steps are also included.

[0078] S301: The core network sends the operating status data of the unmanned agricultural machinery terminal to at least one cloud control platform; In this embodiment, the system may further include at least one cloud control platform, with the core network communicatively connected to the at least one cloud control platform. In practical applications, the at least one cloud control platform may be a regional cloud control platform or an edge cloud control platform.

[0079] In practical applications, cloud control platforms are typically deployed as business platforms within data centers. They are generally used to process operational data from unmanned agricultural machinery terminals, including but not limited to aggregation, processing, and analysis. They can also generate monitoring interfaces and command decisions based on this operational data. The core network can communicate with the cloud control platform through its User Plane Function (UPF). The User Plane Function typically refers to the core network's data forwarding plane, used to route corresponding data to designated target platforms. Furthermore, the core network can communicate with at least one cloud control platform through at least one UPF within the core network.

[0080] It should be noted that the user plane function can be deployed at the network edge, connecting with the edge cloud control platform located in the edge data center. In this way, the core network can directly route the operational data of the unmanned agricultural machinery terminal to the edge cloud control platform through this edge user plane function, thus meeting low-latency processing requirements.

[0081] Furthermore, the core network can send the operating status data of the unmanned agricultural machinery terminals to one or more cloud control platforms. For example, the core network can send the operating status data of the unmanned agricultural machinery terminals to the edge cloud control platform responsible for real-time control and the regional cloud control platform responsible for coordinated scheduling, respectively. In this way, the operating status data of the unmanned agricultural machinery terminals can be sent to one or more service platforms for processing through the data routing capabilities of the core network.

[0082] S302: At least one cloud control platform determines control commands based on the operating condition data of the unmanned agricultural machinery terminal.

[0083] As described in S204 above, in practical applications, control commands can be determined based on the operating condition data of the unmanned agricultural machinery terminal. Furthermore, control commands can be determined by analyzing the operating condition data of the unmanned agricultural machinery terminal through at least one cloud control platform. For example, a return command upon completion of the task can be generated based on the operational status data of the unmanned agricultural machinery terminal; a path replanning command can be generated based on the environmental image data of the unmanned agricultural machinery terminal.

[0084] S303: At least one cloud control platform sends the control command to the core network.

[0085] It is understood that the core network can communicate with at least one cloud control platform through at least one UPF in the core network. In this way, at least one cloud control platform can send the control commands to the core network through the corresponding UPF.

[0086] Furthermore, such as Figure 3 As shown, in Figure 2 Based on the method shown, after step S303, the following steps are also included.

[0087] S304: At least one cloud control platform sends its own operating status data, control commands, and / or the operating status data of the unmanned agricultural machinery terminal to the central cloud control platform. In this embodiment, the system further includes a central cloud control platform, and at least one cloud control platform is communicatively connected to the central cloud control platform. The central cloud control platform is used to schedule the at least one cloud control platform.

[0088] In practical applications, a central cloud control platform typically refers to a business management platform deployed in a central data cloud. It is usually used to schedule the at least one cloud control platform. Specifically, the at least one cloud control platform may include, but is not limited to, an edge cloud control platform and / or a regional cloud control platform.

[0089] Furthermore, communication connections between the edge cloud control platform and / or regional cloud control platform and the central cloud control platform can be established via dedicated network lines, or via the internet. Through these connections, the edge cloud control platform and / or regional cloud control platform can send their own operational status data, generated control commands, and received operating condition data from unmanned agricultural machinery terminals to the central cloud control platform. The central cloud control platform can receive its own operational status data, generated control commands, and received operating condition data from the unmanned agricultural machinery terminals from the edge cloud control platform and / or regional cloud control platform.

[0090] Furthermore, the central cloud control platform can schedule edge cloud control platforms and / or regional cloud control platforms. For example, it can adjust the computing logic or task execution strategy of the edge cloud control platforms and / or regional cloud control platforms by modifying configuration parameters or issuing policy adjustment commands. Specifically, the central cloud control platform can determine the scheduling of at least one cloud control platform based on the data received by the central cloud control platform. Alternatively, it can determine the scheduling of at least one cloud control platform based on other preset rules.

[0091] In some possible implementations, the central cloud control platform may further include a model library. Edge cloud control platforms and / or regional cloud control platforms can call the model library, which typically includes at least one business model. This business model can be used to determine corresponding control commands based on the operating condition data of the unmanned agricultural machinery terminal. For example, the model library of the central cloud control platform includes a job path planning model. The regional cloud control platform can call the job path planning model and, based on the operating condition data of the unmanned agricultural machinery terminal, obtain the corresponding job path control command as output. That is, the central cloud control platform also includes a model library, which includes at least one business model used to determine corresponding control commands based on the operating condition data of the unmanned agricultural machinery terminal.

[0092] It should be noted that, in this way, step 302 can specifically include: the at least one cloud control platform receiving the operating condition data of the unmanned agricultural machinery terminal and calling at least one business model in the model library of the central cloud control platform; the at least one cloud control platform determining control instructions based on the operating condition data of the unmanned agricultural machinery terminal and at least one business model in the model library.

[0093] In some possible implementations, the central cloud control platform can be used to aggregate the aforementioned data and provide users with data display or interaction. Specifically, it can grant data access to authorized users through API interfaces or web service portals for data display. Alternatively, the central cloud control platform can also construct a digital twin of the unmanned agricultural machinery service system based on the received data, enabling the display or interaction of unmanned agricultural machinery terminal operating data.

[0094] Understandably, the central cloud control platform can receive operating data from unmanned agricultural machinery terminals of various business flow types, such as the location and equipment status of the unmanned agricultural machinery terminals. When necessary, the central cloud control platform can also receive images of the surrounding environment of the unmanned agricultural machinery and display the data.

[0095] Of course, the edge cloud control platform and / or regional cloud control platform can also process the operating data of the unmanned agricultural machinery terminal before sending it to the central cloud control platform. The central cloud control platform can receive the processed operating data sent by the edge cloud control platform and / or regional cloud control platform. For example, the regional cloud control platform determines the operation progress of the unmanned agricultural machinery terminal through information such as the preset trajectory, historical trajectory, and current location of the unmanned agricultural machinery terminal, and sends the operation progress of the unmanned agricultural machinery terminal to the central cloud control platform; the central cloud control platform receives the operation progress of the unmanned agricultural machinery terminal sent by the regional cloud control platform and displays the data.

[0096] See Figure 4 This is a flowchart illustrating another communication method for an unmanned agricultural machinery service system provided in an embodiment of this application, as shown below. Figure 4 As shown, in Figure 2Based on the method shown, before step S203, the following steps are also included.

[0097] S401: The core network sends a command to the bearer network to create a private network channel for unmanned agricultural machinery.

[0098] In practical applications, the command to create a dedicated network channel for unmanned agricultural machinery is typically a control signaling generated by the core network. This signaling instructs the bearer network to establish a dedicated data channel between the access network and the core network for transmitting data related to the unmanned agricultural machinery terminal. Furthermore, the command to create a dedicated network channel for unmanned agricultural machinery may also include specific configurations for the dedicated network channel, including but not limited to bandwidth requirements, latency metrics, or routing strategies.

[0099] S402: The bearer network responds to the command to create a private network channel for unmanned agricultural machinery and creates a private network channel for unmanned agricultural machinery.

[0100] In this embodiment of the application, the bearer network and the core network are communicatively connected. The core network can send an instruction to the bearer network to create an unmanned agricultural machinery private network channel. The bearer network receives and responds to the instruction sent by the core network to create an unmanned agricultural machinery private network channel and creates the unmanned agricultural machinery private network channel.

[0101] Specifically, a dedicated network channel for unmanned agricultural machinery can be established through network slicing technology. For example, an isolated channel can be established in the bearer network through hard slicing of Flexible Ethernet (FlexE) technology, that is, a dedicated network channel for unmanned agricultural machinery can be established.

[0102] To more clearly illustrate the technical solutions of the embodiments of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings and a complete embodiment.

[0103] See Figure 5 This is a schematic diagram of the network architecture of an unmanned agricultural machinery service system provided in an embodiment of this application, as shown below. Figure 5 As shown, the unmanned agricultural machinery service system 520 includes an access network 521, a bearer network 522, a core network 523, and a cloud control platform 524. The access network 521 includes a first base station 5211 and a second base station 5212; the bearer network 522 includes a dedicated unmanned agricultural machinery network channel 5221; the core network 523 includes an edge UPF 5231 and a regional UPF 5232; and the cloud control platform 524 includes an edge cloud control platform 5241, a regional cloud control platform 5242, and a central cloud control platform 5243.

[0104] Furthermore, the first base station 5211 and the second base station 5212 are communicatively connected to the unmanned agricultural machinery dedicated network channel 5221 in the bearer network; the unmanned agricultural machinery dedicated network channel 5221 in the bearer network is communicatively connected to the edge UPF 5231 and the regional UPF 5232 in the core network 523; the edge UPF 5231 and the regional UPF 5232 in the core network 523 are communicatively connected to the edge cloud control platform 5241 and the regional cloud control platform 5242, respectively; the edge cloud control platform 5241 and the regional cloud control platform 5242 are communicatively connected to the central cloud control platform 5243.

[0105] The unmanned agricultural machinery terminal 510 includes a first unmanned agricultural machinery 511, a second unmanned agricultural machinery 512, and a third unmanned agricultural machinery 513. Specifically, the first base station 5211 in the access network 521 establishes communication links with the first unmanned agricultural machinery 511, the second unmanned agricultural machinery 512, and the third unmanned agricultural machinery 513, respectively; the second base station 5212 establishes communication links with the third unmanned agricultural machinery 513 and the user mobile device 530, respectively.

[0106] In this embodiment of the application, the core network 523 can send a command to the bearer network 522 to create a private network channel for unmanned agricultural machinery. After responding to the command, the bearer network 522 creates a private network channel 5221 for unmanned agricultural machinery through network slicing technology (such as FlexE hard slicing).

[0107] The unmanned agricultural machinery terminal 510 first sends its own operating status data to the access network 521. The access network 521 receives the operating status data through the first base station 5211 and the second base station 5212. Among them, the first unmanned agricultural machinery 511 to the third unmanned agricultural machinery 513 communicate with the first base station 5211, and the third unmanned agricultural machinery 513 can also communicate with the second base station 5212. The unmanned agricultural machinery terminal 510 can generate a communication key through the identity authentication module, and establish a secure communication link after being authenticated by the access network 521. Subsequently, the access network 521 sends the operating status data to the bearer network 522, and the bearer network 522 transmits it to the core network 523 through the unmanned agricultural machinery private network channel 5221. If the operating status data contains multiple service flow types, the bearer network 522 can also deploy matching service flow channels within the unmanned agricultural machinery private network channel 5221 to achieve differentiated data transmission. After receiving the operating condition data, the core network 523 sends the operating condition data to the edge cloud control platform 5241 or the regional cloud control platform 5242 through the edge UPF 5231 or the regional UPF 5232. The cloud control platform then aggregates and analyzes the data.

[0108] The edge cloud control platform 5241 and the regional cloud control platform 5242 generate control commands based on operating condition data and send them to the core network 523. The core network 523 sends the control commands to the access network 521 via the unmanned agricultural machinery dedicated network channel 5221 of the bearer network 522 or the command data channel in the unmanned agricultural machinery dedicated network channel 5221. Then, the first base station 5211 or the second base station 5212 of the access network 521 distributes the commands to the unmanned agricultural machinery terminal 510. At the same time, the access network 521 can send control commands or operating condition data to the user's mobile device 530. In addition, the edge cloud control platform 5241 and the regional cloud control platform 5242 can also report their own operating condition data, control commands, and unmanned agricultural machinery terminal operating condition data to the central cloud control platform 5243. The central cloud control platform 5243 can schedule the edge cloud control platform 5241 and the regional cloud control platform 5242.
