[0002] New power system operations involve the precise control of distributed generation-grid-load-storage units, which are typical time-sensitive networks. For such time-sensitive networks, the latency between the access network and the core network during resource fusion and scheduling can significantly impact their operation. Excessive latency can lead to delayed responses from the time-sensitive network, making precise control impossible. Summary of the Invention

[0003] This application provides a method, apparatus, system, terminal, and medium for controlling distributed heterogeneous wireless networks, in order to reduce the latency of information transmission between the access network and the core network.

[0004] This application is achieved through the following technical solution:

[0005] In a first aspect, embodiments of this application provide a method for controlling a distributed heterogeneous wireless network, including:

[0006] The system acquires control information transmitted from the wireless mesh network to the core network via satellite, and acquires the first transmission delay. The control information represents the resource scheduling requirements between the access network and the core network, and the first transmission delay represents the information transmission delay of fiber optic backhaul or wireless backhaul between the core network and the access network.

[0007] Obtain each node in the wireless mesh network at the access network end, and obtain the mesh transmission delay between each node and the access network.

[0008] Based on multiple mesh transmission delays and the first transmission delay, a distributed heterogeneous wireless network control scheme is obtained. The distributed heterogeneous wireless network control scheme characterizes the way information is transmitted between the access network and the core network when the distributed heterogeneous wireless network needs to perform resource scheduling.

Specifically, this includes: obtaining the first transmission time between the core network and the satellite, and the second transmission time between the satellite and each node in the wireless mesh network. Based on the first transmission time, the second transmission time corresponding to each node, multiple mesh transmission delays, and the first transmission delay, a distributed heterogeneous wireless network control scheme is obtained.

[0010] In conjunction with the first aspect, among some possible implementations, a distributed heterogeneous wireless network control scheme is obtained based on the first transmission time, the second transmission time corresponding to each node, multiple mesh transmission delays, and the first transmission delay. Specifically, this includes: obtaining multiple wireless mesh transmission delays based on the first transmission time, the second transmission time corresponding to each node, and multiple mesh transmission delays, where the second transmission time and mesh transmission delays correspond one-to-one. Based on the multiple wireless mesh transmission delays and the first transmission delay, the minimum transmission delay is obtained, and the transmission scheme corresponding to the minimum transmission delay is the distributed heterogeneous wireless network control scheme.

[0011] In conjunction with the first aspect, in some possible implementations, the formula for calculating the latency of wireless mesh transmission is as follows:

[0012] c = c1 + c2 + c3

[0013] Where c is the wireless mesh transmission delay, c1 is the first transmission time, c2 is the second transmission time, and c3 is the mesh transmission delay corresponding to the second transmission time.

[0014] In conjunction with the first aspect, in some possible implementations, after obtaining the distributed heterogeneous wireless network control scheme based on multiple mesh transmission delays and a first transmission delay, the method further includes: obtaining the type of the access network and the types of all networks in the distributed heterogeneous wireless network; obtaining the transmission priority based on the types of all networks and the access network; and sending control information to the core network based on the transmission priority and the access network type.

[0015] In conjunction with the first aspect, in some possible implementations, control information is sent to the core network based on transmission priority and access network type. Specifically, this includes: when the access network type has the highest transmission priority, the control information for the access network is sent first. When the access network type has the second highest transmission priority, it is determined whether there is a type corresponding to the highest priority among all types. The control information for the access network corresponding to the highest priority is sent first, and then the control information for the access network corresponding to the second priority is sent.

[0016] Secondly, embodiments of this application provide a distributed heterogeneous wireless network control device, comprising:

[0017] The acquisition module is used to acquire the control information transmitted from the wireless mesh network to the core network via satellite, and to acquire the first transmission delay. The control information represents the resource scheduling requirements between the access network and the core network, and the first transmission delay represents the information transmission delay of fiber optic backhaul or wireless backhaul between the core network and the access network.

[0018] The latency module is used to obtain the latency of each node in the wireless mesh network at the access network end and to obtain the mesh transmission latency between each node and the access network.

[0019] The result module is used to obtain a distributed heterogeneous wireless network control scheme based on multiple mesh transmission delays and a first transmission delay. The distributed heterogeneous wireless network control scheme characterizes the way information is transmitted between the access network and the core network when the distributed heterogeneous wireless network needs to perform resource scheduling.

[0020] Thirdly, embodiments of this application provide a control terminal, including: a processor and a memory, the memory being used to store a computer program, wherein the processor executes the computer program to implement the distributed heterogeneous wireless network control method as described in any of the first aspects.

[0021] Fourthly, embodiments of this application provide a computer-readable storage medium storing a computer program that, when executed by a processor, implements the distributed heterogeneous wireless network control method as described in any of the first aspects.

[0023] The wireless mesh network is set up on the access network side. There are multiple nodes in the wireless mesh network, and each node is connected to the access network.

[0024] Satellites are used to receive control information and then transmit it to the core network.

[0025] Both fiber optic backhaul lines and wireless backhaul lines are used for communication between the core network and the access network. The first transmission delay characterizes the delay when the fiber optic backhaul line or the wireless backhaul line transmits information.

[0026] The control terminal is set on the access network side. The control terminal is used to calculate the control scheme of the distributed heterogeneous wireless network based on the first transmission delay and the mesh transmission delay between each node in the wireless mesh network and the access network.

[0027] The access network sends control information to the core network according to the distributed heterogeneous wireless network control scheme.

[0028] It is understood that the beneficial effects of the second to fifth aspects mentioned above can be found in the relevant descriptions in the first aspect mentioned above, and will not be repeated here.

[0029] The beneficial effects of the embodiments in this application compared with the prior art are:

[0030] This application compares the latency of three schemes—wireless mesh network combined with satellite transmission, fiber optic backhaul, and wireless backhaul—to determine the optimal transmission method. This prevents high latency caused by busy transmission of a particular method. By selecting the optimal transmission method, high latency can be avoided. When the latency of one scheme is too high, a low-latency transmission method is matched to reduce the information transmission latency between the access network and the core network. For time-sensitive networks, this can improve their precise control capabilities and enable timely responses.

[0043] New power system operations involve precise control of distributed source-grid-load-storage units, which are typical time-sensitive networks (TSNs). For such TSNs, the latency between the access network and the core network during resource fusion scheduling significantly impacts their performance. Excessive latency leads to delayed responses from the TSN, hindering precise control. To address this issue, this application proposes a distributed heterogeneous wireless network control method. By selecting the information transmission method with the minimum latency between the access network and the core network, the latency of typical TSNs is reduced, enabling them to respond promptly and achieve precise control.

[0044] Figure 1 This is a flowchart illustrating a distributed heterogeneous wireless network control method according to an embodiment of this application, referring to... Figure 1 The detailed description of the control method for this distributed heterogeneous wireless network is as follows:

[0045] Step 101: Obtain the control information transmitted by the wireless mesh network to the core network via satellite, and obtain the first transmission delay. The control information represents the resource scheduling requirements between the access network and the core network, and the first transmission delay represents the information transmission delay of fiber optic backhaul or wireless backhaul between the core network and the access network.

[0046] Step 102: Obtain each node in the wireless mesh network of the access network and obtain the mesh transmission delay between each node and the access network.

[0047] Specifically, for this method, such as Figure 2 As shown, there are three communication methods for control information to be transmitted from the access network to the core network. The first is that the control information is transmitted to the core network via fiber optic backhaul lines. The second is that the control information is transmitted to the core network via wireless backhaul lines. The third is that the control information is first transmitted to nodes in the wireless mesh network, the nodes transmit the control information to the satellite, and then the satellite transmits the control information to the core network. The transmission direction of the control information is from the access network to the core network.

[0048] Step 103: Based on multiple mesh transmission delays and the first transmission delay, a distributed heterogeneous wireless network control scheme is obtained. The distributed heterogeneous wireless network control scheme characterizes the way information is transmitted between the access network and the core network when the distributed heterogeneous wireless network needs to perform resource scheduling.

[0049] For example, a distributed heterogeneous wireless network control scheme is obtained based on multiple mesh transmission delays and a first transmission delay. Specifically, this includes: obtaining the first transmission time between the core network and the satellite, and the second transmission time between the satellite and each node in the wireless mesh network. Based on the first transmission time, the second transmission time corresponding to each node, multiple mesh transmission delays, and the first transmission delay, a distributed heterogeneous wireless network control scheme is obtained.

[0050] For example, based on the first transmission time, the second transmission time corresponding to each node, multiple mesh transmission delays, and the first transmission delay, a distributed heterogeneous wireless network control scheme is obtained. Specifically, this includes: obtaining multiple wireless mesh transmission delays based on the first transmission time, the second transmission time corresponding to each node, and the multiple mesh transmission delays, wherein the second transmission time and the mesh transmission delays correspond one-to-one. Based on the multiple wireless mesh transmission delays and the first transmission delay, the minimum transmission delay is obtained, and the transmission scheme corresponding to the minimum transmission delay is the distributed heterogeneous wireless network control scheme.

[0051] Specifically, choosing the transmission scheme with the minimum transmission delay helps typical time-sensitive networks respond promptly to demand and achieve precise control.

[0052] For example, the formula for calculating the latency of wireless mesh transmission is as follows:

[0053] c = c1 + c2 + c3

[0054] Where c is the wireless mesh transmission delay, c1 is the first transmission time, c2 is the second transmission time, and c3 is the mesh transmission delay corresponding to the second transmission time.

[0055] For example, after obtaining the distributed heterogeneous wireless network control scheme based on multiple mesh transmission delays and a first transmission delay, the method further includes: obtaining the type of the access network and the types of all networks in the distributed heterogeneous wireless network; obtaining the transmission priority based on the types of all networks and the access network; and sending control information to the core network based on the transmission priority and the access network type.

[0056] For example, based on transmission priority and access network type, control information is sent to the core network, specifically including: when the access network type has the highest transmission priority, the control information of the access network is sent first. When the access network type has the highest transmission priority, it is determined whether there is a type corresponding to the highest priority among all types. The control information of the access network corresponding to the highest priority is sent first, and then the control information of the access network corresponding to the second priority is sent.

[0057] The aforementioned distributed heterogeneous wireless network control method compares the latency of three schemes—wireless mesh network combined with satellite transmission, fiber optic backhaul, and wireless backhaul—to determine the optimal transmission method. This prevents high latency caused by busy transmission of a particular method. By selecting the optimal transmission method, high latency can be avoided. When the latency of one scheme is too high, a low-latency transmission method is matched to reduce the information transmission latency between the access network and the core network. For time-sensitive networks, this can improve their precise control capabilities and enable timely responses.

[0058] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0061] Optionally, the acquisition module 301 is used to acquire the control information transmitted by the wireless mesh network to the core network via satellite, and to acquire the first transmission delay, wherein the control information represents the resource scheduling requirements between the access network and the core network, and the first transmission delay represents the information transmission delay of fiber optic backhaul or wireless backhaul between the core network and the access network.

[0062] Optionally, the delay module 302 is used to obtain each node in the wireless mesh network at the access network end, and to obtain the mesh transmission delay between each node and the access network.

[0063] Optionally, the result module 303 is used to obtain a distributed heterogeneous wireless network control scheme based on multiple mesh transmission delays and a first transmission delay. The distributed heterogeneous wireless network control scheme characterizes the way information is transmitted between the access network and the core network when the distributed heterogeneous wireless network needs to perform resource scheduling.

[0064] For example, the result module 303 is further configured to: obtain the first transmission time between the core network and the satellite, and the second transmission time between the satellite and each node in the wireless mesh network. Based on the first transmission time, the second transmission time corresponding to each node, multiple mesh transmission delays, and the first transmission delay, a distributed heterogeneous wireless network control scheme is obtained.

[0065] For example, the result module 303 is further configured to: obtain multiple wireless mesh transmission delays based on the first transmission time, the second transmission time corresponding to each node, and multiple mesh transmission delays, wherein the second transmission time and the mesh transmission delays correspond one-to-one. Based on the multiple wireless mesh transmission delays and the first transmission delay, the minimum value of the transmission delay is obtained, and the transmission scheme corresponding to the minimum value of the transmission delay is the distributed heterogeneous wireless network control scheme.

[0066] For example, the formula for calculating the latency of wireless mesh transmission is as follows:

[0067] c = c1 + c2 + c3

[0068] Where c is the wireless mesh transmission delay, c1 is the first transmission time, c2 is the second transmission time, and c3 is the mesh transmission delay corresponding to the second transmission time.

[0069] For example, after obtaining the distributed heterogeneous wireless network control scheme based on multiple mesh transmission delays and a first transmission delay, the result module 303 is further configured to: obtain the type of the access network and the types of all networks in the distributed heterogeneous wireless network; obtain the transmission priority based on the types of all networks and the access network; and send control information to the core network based on the transmission priority and the access network type.

[0070] For example, the result module 303 is further configured to: when the access network type has the first priority in the transmission priority, prioritize sending the access network control information. When the access network type has the second priority in the transmission priority, determine whether there is a type corresponding to the first priority among all types, send the control information of the access network corresponding to the first priority first, and then send the control information of the access network corresponding to the second priority.
